The Singing Machine Company 卖家用卡拉 OK 机起家，2022 年做了 1:30 缩股后登上纳斯达克。2023 年把财年从 3 月底改到 12 月底。生意一直在缩：2023 年 4–12 月九个月收入 2,920 万美元、亏 640 万；2024 年全年收入 2,349 万（其中 SemiCab 只贡献 30 万）。
2024-06-11 签约买 SemiCab, Inc. 的资产（AI 货运撮合平台，创始人 Ajesh Kapoor），7 月 3 日交割，对价 641,806 股（拆前）加 SemiCab 子公司 20% 权益；SemiCab 的印度子公司 SMCB 另以 2025-05-02 的 175 万美元本票买下。2024-09-05 改名 Algorhythm Holdings，9 月 9 日起代码 RIME。2025-08-01 把卡拉 OK 业务连资产带负债以 50 万美元卖给 Stingray Music USA（董事 Peloquin 所在集团的子公司）。之后公司的全部收入来自 SemiCab，而且「几乎全部来自印度客户」（10-K 原话）。
2026-08-19 宣布评估收购一家「为数据中心提供孤岛式发电」的能源公司，8/25 宣布 SemiCab 可能出售、分拆或保留，9/15 宣布完成收购 Azure Energy, LLC、能源成为主营、CEO 换人。

到 2026-06-04 招股书口径：Streeterville 已买走 12,077,557 股，抵掉 1,022.9 万美元余额，均价 $0.847；加 95,694 承诺股。它 2025-12-16 的 13G 只报持有 271,905 股（9.99%）——拿到就卖，合同只限它每周卖出不超过当周成交额的 15%。
股价 $0.2173（9/15 收盘）。四笔的地板 $0.418、$0.4348、$0.282、$0.30 全在市价之上（未清的是 #1 与 #4）。按合同，购股价低于地板时 Streeterville 有权改要现金——它不会用高于市价的地板价买股。于是约 741 万美元本金（含息约 775 万）在股价回到约 $0.33（0.30 ÷ 0.9）之前基本不能靠发股消化，而是每天按 9% 复利涨、由全部资产和 350 万现金抵押担保的债。公司 6/30 手里非受限现金 497 万，半年烧 659 万。
反过来，如果股价涨回 $0.45，剩余余额可换约 1,650 万股，是现在在外股数的 97%；涨回 $1，换约 823 万股。股价越涨，供给越多，这是可变价工具对普通股最直接的含义。
2026-06-29 从 PPP#4 切出 350 万换 3,500 股 Series A，面值 $1,150/股 = 402.5 万美元，9% 日复利、按季付，公司可选现金或再发优先股（PIK）。它不转普通股、没有投票权、持有人不能要求赎回；公司想赎回要付清算额的 110%。它排在所有股本之前。
指定证书第 10 条的契约，只要还有一股优先股在外就有效：不得增减授权股；不得新发股票或可转换证券（豁免：员工股权、既有证券行权、董事会多数无利害董事批准且没有登记权的受限股、总额不超过 500 万美元的融资）；不得质押资产；不得处置重大资产；除纳斯达克缺陷外不得反拆；未经优先股多数持有人同意不得做「根本性交易」（合并、出售全部资产、他人取得 50% 以上投票权等）。违约面值 +15%、可累计三次，回报升到 15%，且持有人可申请禁令禁止公司向任何人发股直到优先股被全额赎回。
直接含义：Azure 收购是以股付对价的资产收购，要么落在豁免（受限股、无登记权），要么拿到了 Streeterville 同意——两者 8-K 都该写。若 Azure 拿到的普通股是「无登记权的受限股」，它们至少六个月不能公开卖（Rule 144），这对流通盘是好消息，但对 Azure 卖方是锁定。
第 5 条 回报：Section 5. Preferred Return . (a) Each share of Series A Stock shall accrue a rate of return on the Stated Value at the rate of nine percent (9%) per annum, to be determined pro rata for any fractional year periods (the “Preferred Return”). The Preferred Return shall accrue on each share of Series A Stock from its Issuance Date and shall be payable or otherwise settled as set forth herein. Following the occurrence of an Event of Default (as defined below), the Preferred Return will increase to 15% per annum. (b) The Preferred Return shall compound daily and be payable on a quarterly basis, within five (5) Trading Days following the end of each calendar quarter, either in cash or via the issuance to the applicable Series A Holder of an additional number of shares of Series A Stock equal to (i) the Preferred Return then accrued and unpaid, divided by (ii) $1,150.00, with the election as to payment in cash or via the issuance of additional shares of Series A Stock to be determined in the discretion of the Corporation. (c) In the event that the Corporation elects to pay any Preferred Return via the issuance of shares of Series A Stock, no fractional shares of Series A Stock shall be issued, and the Corporation shall pay in cash the Preferred Return that would otherwise be payable via the issuance of a fractional share of Series A Stock. Section 6. Liquidation, Dissolution or Winding Up . In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, each share of Series A Stock shall be entitled to be paid out of the assets of the Corporation available for distribution to its shareholders before any payment shall be made to the holders of Common Stock by reason of their ownership thereof, an amount per share of Series A Stock equal to the Stated Value at such time plus any accrued and unpaid Preferred Return (as applicable, the “Series A Preferred Liquidation Amount”). If upon any such liquidation, dissolution or winding up of the Corporation, the assets of the Corporation available for distribution to its shareholders shall be insufficient to pay the Series A Preferred Liquidation Amount, the Series A Holders with respect to their shares of Series A Stock shall share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. Following the payment of the Series A Preferred Liquidation Amount, if there are any remaining assets of the Corporation available for distribution to its shareholders, the Series A Stock shall not participate in such distributions.
第 7 条 公司选择赎回：Section 7. Corporation Optional Redemption . (a) Subject to the terms and conditions herein, the Corporation may elect, in the sole discretion of the Board, to redeem all or any portion of the Series A Stock then issued and outstanding from all of the Series A Holders (a “Corporation Optional Redemption”) by paying to the applicable Series A Holders an amount in cash equal to the Series A Preferred Liquidation Amount then applicable to such shares of Series A Stock being redeemed in the Corporation Optional Redemption multiplied by 110% (the “Redemption Price”). For the avoidance of doubt, any redemptions made in connection with a Fundamental Transaction will be paid at the Redemption Price. (b) The Corporation shall provide written notice of any Corporation Optional Redemption to the Series A Holders within ten (10) Trading Days following the determination of the Board to consummate the applicable Corporation Optional Redemption, and thereafter such Corporation Optional Redemption shall be completed on the third (3 rd ) Trading Day following the delivery of such notice, and at such time the Corporation shall deliver to the Series A Holders the Redemption Price in valid funds. Each Series A Holder agrees to execute and deliver to the Corporation such instruments and documents, and to take such actions, as reasonably required to consummate the Corporation Optional Redemption.
第 10–12 条 契约、违约、不得由持有人要求赎回：Section 10. Covenants . Until such time as no shares of Series A Stock remain outstanding, the Corporation and any subsidiary (to the extent applicable) will at all times comply with the following covenants: (a) The Corporation will timely file on the applicable deadline (inclusive of any timely filed extensions) all reports required to be filed with the SEC pursuant to Sections 13 or 15(d) of the Exchange Act, and will take all reasonable action under its control to ensure that adequate current public information with respect to the Corporation, as required in accordance with Rule 144 of the Securities Act, is publicly available, and will not terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and regulations thereunder would permit such termination. (b) The Common Stock will be listed or quoted for trading on any of NYSE, NYSE American or Nasdaq. (c) After the initial issuance of Series A Stock, the Corporation will not issue any new shares of Series A Stock to anyone other than the initial holder of Series A Stock. (d) The Corporation will not increase or decrease the authorized shares of Common Stock or Preferred Stock. (e) The Corporation will not make any Restricted Issuance. (f) The Corporation shall not enter into or extend any agreement or otherwise agree to any covenant, condition, or obligation that locks up, restricts in any way or otherwise prohibits the Corporation (i) from entering into a variable rate transaction with any Series A Holder or any Affiliate of any Series A Holder, or (ii) from issuing Common Stock, Preferred Stock, warrants, convertible notes, other debt securities, or any other of the Corporation’s securities to any Series A Holder or any Affiliate of any Series A Holder. (g) The Corporation will not pledge or grant a security interest in any of its assets. (h) The Corporation will not, and will not enter into any agreement or commitment to, dispose of any assets or operations outside the ordinary course of business that are material to the Corporation’s operations. (i) Except in connection with satisfaction of a Nasdaq deficiency notice, the Corporation will not, and will not enter into any agreement or commitment to, undertake or complete any reverse split of any class of Common Stock or Preferred Stock. (j) The Corporation will not consummate a Fundamental Transaction or enter into an agreement to consummate a Fundamental Transaction without the consent of the Required Holders. Section 11. Covenant Default . (a) Event of Default . The Required Holders may elect to declare an “Event of Default” if any of the following conditions or events shall occur and be continuing: (i) The Corporation fails to fully comply with any covenant, obligation or agreement of the Corporation in this Certificate of Designation (other than payment or issuance defaults which are addressed in subparagraph (ii) below) or a breach of any covenant owed to any Series A Holder in any other agreement between the Corporation and such Series A Holder, and such failure is not cured within five (5) Trading Days of the occurrence of such event; (ii) The Corporation fails to pay any amount due and payable to the Series A Holders pursuant to and as required by this Certificate of Designation, or fails to issue any additional shares of Series A Stock to the Series A Holders pursuant to and as required by this Certificate of Designation, and such failure, if known to the Series A Holders and reasonably possible of cure, is not cured within five (5) Trading Days of the occurrence of such event; or (iii) The Corporation shall (1) apply for or consent to the appointment of, or the taking of possession by, a receiver, custodian, trustee or liquidator; (2) make a general assignment for the benefit of the Corporation’s creditors; or (3) commence a voluntary case under the U.S. Bankruptcy Code as now and hereafter in effect, or any successor statute. (b) Consequences of Events of Default . Upon the occurrence of an Event of Default the Stated Value will automatically increase by fifteen percent (15%) (the “Default Effect”). The Default Effect may be applied up to three (3) times for three (3) separate Events of Default. If an Event of Default has occurred (i) the Series A Holders shall have the right to pursue any remedies that the Required Holders may have under applicable law and/or in equity; and (ii) the Series A Holders shall have the right to seek and receive injunctive relief from a court or an arbitrator prohibiting the Corporation from issuing any of its Common Stock or Preferred Stock to any party unless all the shares of Series A Stock owned by the Series A Holders are redeemed in full simultaneously with such issuance. (c) Expenses . In the event that any Series A Holder incurs expenses in the enforcement of its rights hereunder, including but not limited to reasonable attorneys’ fees, then the Corporation shall immediately reimburse such Series A Holder the reasonable costs thereof. Section 12. No Redemption at the Option of Series A Holder . Notwithstanding anything in this Certificate of Designation to the contrary, the Series A Stock shall not be redeemable at the option of any Series A Holder, and no Series A Holder shall have any right, under any circumstance or upon the occurrence of any event (including any Event of Default or any Fundamental Transaction), to require, demand or compel the Corporation to redeem, repurchase or otherwise acquire any shares of Series A Stock, or to otherwise require the Corporation to transfer cash or other assets in respect of the Series A Stock. Every redemption of the Series A Stock shall be effected solely at the option and in the sole discretion of the Corporation.

EthanClaude01 回查 · 2026-09-17：反拆与授权股要逐次查一手件。RIME 两次已落地的反拆，处理方式不同：
① 2022-05-23 生效的 1:30（1996 年起的老壳、当时叫 The Singing Machine）：授权股没有同步缩减，普通股授权仍是 100,000,000 股。依据 8-K 2022-05-25 Item 5.03（5/19 向特拉华递交章程修正、5/23 生效）与 424B4 2022-05-25 的资本结构表（拆后在外 1,221,209 股，同页写明「100,000,000 shares authorized」）。该次章程修正的附件 3.1 是扫描图片，无可检索文本，故以 8-K 正文与招股书表为准。
② 2025-02-10 生效的 1:200：授权股不但没缩，反而同次从 1 亿增至 8 亿。依据 8-K 2025-01-13 Item 5.07（年会同时通过反拆授权与授权股 100,000,000 → 800,000,000）与 8-K 2025-01-17 Item 5.03（董事会定 1:200，并「to effect the reverse split and to increase the Company’s authorized shares of common stock from 100,000,000 to 800,000,000」）；10-Q 2026-08-14 资产负债表仍列「800,000,000 and 100,000,000 shares authorized」。
③ 授权股是固定数字、有面值（普通股 $0.01、优先股 $1.00），不是 unlimited/无面值，因此「授权余量 ÷ 在外股」这个比值有定义：8 亿 ÷ 16,990,135 ≈ 47.1 倍（2026-08-11 口径）。
本补注只补出处与逐次结论，不改原判断；原文保留。
更正（2026-09-18 基底回查）：上面「两次已落地的反拆」这句不完整。按 EDGAR 全部 833 份申报（1996-06-28 起）核，已落地的反拆共三次：1998-04-01 的 1:10（破产重组计划项下，8-K 1998-03-25 公告、10-KSB 1998-12-08 附注 8 记录「effectuated a one for ten (1:10) reverse stock split」，同一附注写明「During April, 1998, the Company filed an amendment to its Articles of Incorporation increasing the authorized shares … to ten million (10,000,000) shares」——授权股是增加、不是缩减；10-KSB 1999-08-09 记 1999-03-08 股东会再把授权由 1,000 万增至 7,500 万）、2022-05-23 的 1:30、2025-02-10 的 1:200。三次都没有同步缩减授权股，其中 1998 与 2025 两次还在同期增加了授权股。原句保留不删。
检索基底（2026-09-18 回查）：官方申报总数 833 份（SEC submissions JSON，1996-06-28 至 2026-08-14，filings.files[] 无分片，即 recent 已是全量）；本机实际下载 207 份（2023-01-01 起 199 份 ＝ 该区间全量、0 缺件；另定向补拉 8 份 pre-2023：2022 年 3 份，1998、1999、2001、2008、2011 各 1 份）；未纳入 626 份，原因是基底预设从 2023-01-01 起，不是限流、超时、下载失败或脚本去重；其中 1996–2000 年的 36 份也不在 EDGAR 全文检索覆盖范围（全文检索只覆盖 2001 年起）。未转成文本的附件另计：221 个（218 个 JPG ＋ 3 个 PDF），分布在 54 份申报里；其中 7 份附件是纯图片、无可检索正文，包括 2025-01-17 那份 1:200 反拆章程修正的附件 3.1 与 2024-09-06 改名章程修正的附件 3.1——本页这两处结论都改用 8-K 正文与招股书资本结构表作依据，没有只靠摘要。
四个数分开写（2026-09-18 补核）：①应有份数（官方台账）833 份（其中 2023-01-01 起 199 份）；（注：上一段写的「已下载 207 份 / 补拉 8 份」是把那份下成报错页的 1998-02-24 10-KSB40 算作未取回；重下成功后为 208 份 / 补拉 9 份，以本段四个数为准。）②实际取回份数 208 份（2023-01-01 起 199/199，加定向补拉的 pre-2023 9 份）；③可全文检索份数 208 份（每份至少有一份文件的纯文本 ≥ 400 字符）；④未转成文本的附件 221 个（218 个 JPG ＋ 3 个 PDF，分布在 54 份申报，其中 7 份是纯图片附件）。（2026-09-18 第五轮实物复核补正：这 221 个是已解包落盘的图片/PDF 文件；另有 6 个 GRAPHIC 文档内嵌在「整份提交件」.txt 里、从未以独立文件落盘（2026-08-14 10-Q、2008-09-23 8-K、2022-05-25 的 8-K 与 424B4），按文档实体计应为 227 个非文本文档、分布 58 份申报。份数四个数不受影响。）（2026-09-18 第六轮补核 · PDF 单独过一关：这 3 个落盘 PDF 都能抽出文本（pdftotext 各 668 / 668 / 682 个非空白字符，各 1 页；其中两个是同一封 SEC 意见函在同目录下的副本），而且这两份 UPLOAD 申报本身就各带一个 TYPE=TEXT-EXTRACT 的 .txt 孪生件（754 / 768 字符），内容一字不缺。真正只能靠人眼看图的只有图片：224 个（218 个落盘 JPG ＋ 6 个内嵌 GRAPHIC）。同轮还做了全库扩展名／魔数比对：基底四个根目录 4,776 个文件中 0 个魔数不符、0 个 0 字节。）这四个数不合成一句写：台账说「有多少」，取回说「真拿到多少」，可检索说「能被文字检索到多少」，未转文本说「只能靠人眼看图的有多少」。
空文件与无效文件核查：全量扫描本机 4,780 个文件，0 字节文件 0 个；但首轮确有 1 份「文件存在、内容无效」——1998-02-24 的 10-KSB40（acc 0000950170-98-000355）当时下成 311 字节的 S3 报错页（NoSuchKey，用了旧式扁平路径），份数看着对、全文检索却扫不到任何内容；已按正确路径重取成功（399,734 字节，内容为破产重组计划下「1 x 10 reverse split」的说明），并已计入上面的取回与可检索份数。
内容指纹扫描（2026-09-18 第三条补核）：「非空」不等于「有内容」——SEC 限流时会回一个约 3KB 的 Undeclared Automated Tool 提示页，它非空、份数也对，却能同时骗过份数对账与 0 字节核查。本机 4,056 个文本类文件（.htm/.txt/.xml/.json）逐个按内容指纹扫过：Undeclared Automated Tool、Request Rate Threshold、Your Request Originates、Access Denied、403、NoSuchKey、<Error><Code>、captcha 等字样0 命中（2026-09-19 扫描范围补正：上面那 4,056 个是按扩展名白名单 .htm/.html/.txt/.xml/.json/.sgml/.nc 挑出来的，白名单本身也是一道「我自己划的范围」。已把先前被它排除、但其实是文本的 324 个文件（110 个 .xsd、105 个 .js、105 个 .css、4 个 .csv）按同一条七步管线补扫：取件失败 0、解析失败 0、解析出值 324、命中 0。文本类文件合计 4,380 个全部扫过、全部 0 命中；余下 396 个确系二进制（218 JPG、107 ZIP、68 XLSX、3 PDF），其中 PDF 已另行抽文本核过。）；另把 162 个小于 4KB 的 .htm/.txt 逐个看过正文，全部是合法内容（图片型附件外壳、EFFECT 生效通知、SEC 问询函文本抽取）。指纹写法按 2026-09-18 全舰纪律修正为只用整句（词边界不够：\bRate Limit\b 照样命中「sepa-rate Limit-ed Power of Attorney」，因为连字符本身就是词边界，所以 Rate Limit、Access Denied 这类短词已整条删出指纹集）（如整句 Your Request Originates from an Undeclared Automated Tool、\bUndeclared Automated Tool\b、<Error><Code>NoSuchKey</Code>），不用 Rate Limit 这类子串宽匹配——SACHClaude 今天就有一例：364KB 托管协议里的正常文字「sepa-rate Limit-ed Power of Attorney」被子串命中，差点把真文件当提示页删掉重下。本席规矩：任何命中都先人工看原文再决定是否重下。上面那份 311 字节文件就是先打开确认内容是 S3 的 <Error><Code>NoSuchKey</Code> XML，才重下的。本库实测：严格指纹 0 命中；而宽口径 /rate limit/i 会命中 14 份文件——全部是贷款协议里的正常条款标题「Interest Rate Limitation」（2024-04-03、2024-11-07、2024-12-06、2025-05-08 四份 8-K 的附件），与 SACH 那一例同类，若按宽口径删档重下就会毁掉真文件。本席原用的指纹集对这 14 份也是 0 命中，故此前的判断与重下都没有误报。独立复跑两套指纹：原宽口径集（15 条）0 命中、严格集（9 条）0 命中；而词写得再松一点误报立刻出现——单词 automated 在本库正常文字里 27 处（多为 DTC 的 Fast Automated Securities Transfer 程序）、rate limit 14 处、denied 3 处，合计 44 处，全是真文件。唯一一例「非空但无内容」就是它，已重下修复。故可全文检索份数仍为 208 份，这个数已按内容而非文件存在与否核定。
2024-12-20 盘中最低 $14.50 → 2025-01-07 盘中最高 $67.72，4.67 倍，先低后高，成交 336 万股（拆后口径）；随后 1/8–1/16 跌回 $7.82。这段发生在 1/13 股东投票反拆之前、12/4 公开发行（含 B 权证 1:1 无现金换股）之后，不在 Tony 定义的「落地日前 15 日」窗口内，本页单列不并入。
口径说明：价格来自纳斯达克官方历史数据（四位小数），已按 1:200 折算成同一口径；Yahoo 的拆前数据只保留两位小数（×200 后只剩 $8/$6/$4 台阶），不能用于盘中高低。2022-05-24 的 1:30 缩股在 2024 年之前，不在统计范围。

直接含义：PPP#4 的地板 $0.30 是按签约日附近价格定的（SPA 公式 20% × 纳斯达克最低价）；Streeterville 在 2/13 把 PPP#2 全部换成股票正好卖在高位；之后股价一路回落，PPP#4 至今一股未换。这三天成交 3.02 亿股，而当时在外股数不过 600 万到 1,400 万——换手是流通盘的二三十倍。
