[0029] The microphone is used to collect the human voice signal and transmit it to the audio processing module;

[0030] The audio processing module is used to receive the accompaniment audio and the human voice signal for audio processing, generate a first audio signal and a second audio signal, the first audio signal is transmitted to the headset through the communication module, and the second audio signal is transmitted to a second intelligent device through the communication module for recording or playing.

[0031] In this embodiment, the sound transmission chamber is used for two purposes: one is to store the headset, and the other is to process and transmit audio data. Specifically, the audio data (accompaniment audio) from the music APP in the first intelligent device and the human voice signal collected by the microphone are transmitted into the audio processing module of the sound transmission chamber, and after sound effect processing, mixing and other processing, a first audio signal and a second audio signal are generated and sent to the headset and the second intelligent device respectively; a recording software such as a recording studio APP is provided in the second intelligent device to record or play the second audio signal to achieve the effect of karaoke. At the same time, the first audio signal is transmitted to the headset to achieve monitoring. The first intelligent device and the second intelligent device in this embodiment are two independent devices, and in other embodiments, they can also be the same intelligent device.

[0032] As described above, the accompaniment audio is various music audios from the first intelligent device. The accompaniment audio is various audio data in various music APPs and is used for accompaniment during karaoke.

[0033] Further, the first audio signal and the second audio signal are human voice signals + accompaniment audio, or human voice signals, or accompaniment audio. The first audio signal and the second audio signal generated within the audio processing module are both generated by performing some processing on the human voice signal and the accompaniment audio, so they include human voice signals or accompaniment audio.

[0034] Furthermore, the communication module within the sound transmission chamber includes a Bluetooth wireless module and a USB sound card module.

[0037] After the audio processing module of the sound transmission chamber processes the human voice signal and the accompaniment audio data, it distributes the data through two channels. One channel is sent to the Bluetooth earphone for playback through the Bluetooth wireless protocol (HFP or A2DP). Specifically, the left earphone receives the left channel (human voice signal + accompaniment audio), and the right earphone receives the right channel (human voice signal + accompaniment audio). The other channel is sent to the second smart device for recording or playback through the USB wireless protocol of the USB sound card module; the audio processing module of the sound transmission chamber mixes the human voice signal and the accompaniment audio data and sends them to the second smart device as the left channel (human voice signal + accompaniment audio) and the right channel (human voice signal + accompaniment audio).

[0038] The second smart device is equipped with a recording system that can record and play the first audio signal; the recording studio APP within the second smart device can perform recording of recording works and playback of sound data, etc.
