[0036] 2. An identity identification module: each TX internally stores a unique identity code (ID). The ID can be fixed at the time of production, or assigned and written by the RX at the first pairing.
[0037] 3. A master control module: located in the RX and / or TX, used for executing control logic. The RX master control module is used to send identification instructions; the TX master control module is used to receive instructions and control the local feedback unit.

[0042] In the embodiments of the present application, the operation of the entire identification system of the present application follows a clear closed-loop data flow, the core of which is the initiation, transmission, analysis and execution of instructions. The following is a detailed step breakdown: Step 1: Identification trigger instruction initiation: Processing logic: The user initiates an identification request through a pre-set interactive interface (such as a physical button on the receiver RX, a function key on the charging box, or a virtual button on the terminal software).
[0043] Data flow: The user's interactive action (such as pressing a button, clicking on a terminal operation interface, etc.) generates an electrical signal.
[0044] Data content: The signal is captured by the master module of the RX (or charging compartment) and generates a structured digital control instruction. The instruction contains at least two key data fields: Target TX identity ID: Specifies the transmitter that needs to respond (such as TX_ID_1).
[0045] Action instruction code: Specifies the action required to be executed (such as CMD_BLINK, CMD_VIBRATE, CMD_BEEP, or a general CMD_IDENTIFY).
[0046] Step 2: Instruction transmission via downlink channel: Processing logic: The device that generates the instruction (RX or charging box) sends the above-mentioned digital control instruction through its wireless communication module.
[0047] Data flow: The digital instruction is encoded and modulated and broadcast or sent point-to-point in the form of radio waves through the wireless audio communication link.
[0048] Data content: The transmitted is a packaged wireless data packet, and the payload (Payload) is the control instruction generated in step 1.
[0049] In some optional implementations of the embodiments of the present application, the wireless audio communication link is a 2.4GHz private protocol or a BLE downlink control channel.
[0050] Step 3: Target TX receives and parses the instruction: Processing logic: The wireless receiving module of the two TXs continuously monitors the communication channel. When a data packet is received, the internal MCU will demodulate and decode the data packet.
[0051] Data flow: Radio signal -> Receiving module (transmission module) -> Digital signal -> TX master MCU (execution module).
[0052] Data content: The MCU parses the target TX identity ID field in the data packet and compares it with the identity code stored in itself. (This scheme is a preset form of broadcast reception) Logical judgment: If the ID matches, continue to parse the action instruction code and prepare for execution; if the ID does not match, ignore the instruction and continue standby.
[0053] Step 4: Target TX master module drives feedback unit to execute: Processing logic: The target TX's master MCU calls the corresponding bottom layer driver program according to the parsed action code, and sends control signals to the specified feedback unit.
[0054] Data flow: MCU -> Drive circuit (such as LED drive IC, motor drive IC, audio power amplifier) -> Physical feedback unit.
[0055] Data content: The specific form of the drive signal varies depending on the feedback unit.
[0056] In the embodiment of the present application, a transmitter identification prompting method applied to a wireless microphone system is provided. The wireless microphone system is composed of at least two transmitters connected with a receiver through a wireless audio communication link. The method comprises the following steps: the receiver receives a transmitter identification request carrying a target transmitter identification; the receiver generates a digital control instruction according to the target transmitter identification, wherein the digital control instruction comprises the target transmitter identification and an action instruction; the receiver sends the digital control instruction to the transmitter; the transmitter receives the digital control instruction and performs identification analysis on the digital control instruction to obtain the target transmitter identification; the transmitter performs identification matching on the target transmitter identification according to the transmitter's own identification information to obtain a matching result; if the matching result is matching, the transmitter performs instruction analysis on the digital control instruction to obtain the action instruction and executes the action instruction; if the matching result is not matching, the transmitter performs an end operation. Compared with the prior art, the transmitter identification information and the target transmitter identification are matched in the present application, so that only the target transmitter can identify and execute the corresponding instruction, effectively avoiding misoperation. In addition, the identification of the target transmitter and the execution of the instruction can be quickly and accurately completed, thereby improving the response speed and efficiency of the system.
[0057] In some optional implementation ways of the embodiment of the present application, the transmitter comprises a master MCU, an audio driving circuit and an audio sounding unit. If the matching result is matching, the transmitter performs instruction analysis on the digital control instruction to obtain the action instruction and executes the action instruction, which specifically comprises the following steps: The master MCU generates an audio signal according to the action instruction; The audio driving circuit performs power amplification on the audio signal to obtain a power-amplified electrical signal; The audio sounding unit converts the power-amplified electrical signal into a sound wave for sound playing operation.
[0058] In some optional implementation ways of the embodiment of the present application, the step of generating an audio signal by the master MCU according to the action instruction specifically comprises the following steps: The master MCU generates a PWM wave of a preset frequency according to the passive buzzer to obtain the audio signal.

[0062] In the embodiment of the application, the transmitter comprises: 1) Audio generating unit: responsible for generating the prompt tone to be played. There are two mainstream implementation methods: ① Passive buzzer: requires external provision of a specific frequency square wave signal to sound. The tone is single, and complex audio cannot be directly played.
[0063] ② Active buzzer: internally integrated with an oscillation circuit, and only needs to give a level signal to sound, and the tone is fixed.
[0064] ③ Micro loudspeaker + audio codec (advanced scheme: built-in speaker): can play complex pre-stored audio segments (such as sound effects and voice).
[0065] 2) Audio driving circuit: this is the key module, in which: ① For the buzzer: a simple triode or MOSFET amplifier circuit is usually enough, because the GPIO port of the MCU is sufficient to drive the required current.
[0066] ② For the loudspeaker: an audio power amplifier (Audio Amp) is needed to amplify the weak audio signal to drive the loudspeaker to emit a large enough sound.
[0067] 3) Storage unit: (only required for advanced scheme) an SPI Flash or other storage, used to store pre-recorded audio files (such as WAV format “Channel One” prompt tone).
[0068] 4) Master MCU: needs to have PWM output (for driving passive buzzer) or DAC output (for generating analog audio signal to drive speaker), or I2S interface (connect external audio codec).
