## Abstract

The present application provides an audio transmission method and an electronic device. When the audio transmission method is performed by a first electronic device, the audio transmission method includes: obtaining target audio; and transmitting an audio signal of the target audio to a first channel playback apparatus or a second channel playback apparatus of a second electronic device through an Ultra Wide Band transport protocol.

## Claims

### Claim 1

An audio transmission method, performed by a first electronic device that is connected to a second electronic device through wireless connections, wherein the second electronic device comprises a first channel playback apparatus and a second channel playback apparatus, and the audio transmission method comprises:
obtaining target audio;
decoding the target audio into a first channel audio signal and a second channel audio signal; and
transmitting an audio signal of the target audio to the first channel playback apparatus through an Ultra Wide Band transport protocol or a Bluetooth transport protocol, wherein the audio signal comprises an indication signal and a combination of the first channel audio signal and the second channel audio signal, wherein the indication signal instructs the first channel playback apparatus to transmit the first channel audio signal to the second channel playback apparatus through the Ultra Wide Band transport protocol.

### Claim 2 (depends on 1)

The audio transmission method according to claim 1, wherein the transmitting an audio signal of the target audio to the first channel playback apparatus through an Ultra Wide Band transport protocol comprises:
calling media access control (MAC) and a physical layer (PHY) in the Ultra Wide Band transport protocol through an alternate medium access control/physical layer (AMP) controller and a protocol adaptation layer (PAL) in the Bluetooth transport protocol; and
transmitting the audio signal of the target audio to the first channel playback apparatus.

### Claim 3 (depends on 1)

The audio transmission method according to claim 1, wherein the transmitting an audio signal of the target audio to the first channel playback apparatus comprises:
transmitting, when a transmission bandwidth required for transmitting the audio signal of the target audio is greater than a preset bandwidth, the audio signal of the target audio to the first channel playback apparatus through the Ultra Wide Band transport protocol.

### Claim 4 (depends on 3)

The audio transmission method according to claim 3, wherein the transmitting an audio signal of the target audio to the first channel playback apparatus:
transmitting, when the transmission bandwidth required for transmitting the audio signal of the target audio is less than or equal to the preset bandwidth, the audio signal of the target audio to the first channel playback apparatus or the second channel playback apparatus through the Bluetooth transport protocol.

### Claim 5

An electronic device, wherein the electronic device is a first electronic device connected to a second electronic device through wireless connections, wherein the second electronic device comprises a first channel playback apparatus and a second channel playback apparatus, wherein the electronic device comprises:
a memory storing a computer program; and
a processor coupled to the memory and configured to execute the computer program, wherein the computer program, when executed by the processor, causes the processor to perform operations comprising:
obtaining target audio;
decoding the target audio into a first channel audio signal and a second channel audio signal; and
transmitting an audio signal of the target audio to the first channel playback apparatus through an Ultra Wide Band transport protocol or a Bluetooth transport protocol, wherein the audio signal comprises an indication signal and a combination of the first channel audio signal and the second channel audio signal, wherein the indication signal instructs the first channel playback apparatus to transmit the first channel audio signal to the second channel playback apparatus through the Ultra Wide Band transport protocol.

### Claim 6 (depends on 5)

The electronic device according to claim 5, wherein the transmitting an audio signal of the target audio to the first channel playback apparatus through an Ultra Wide Band transport protocol comprises:
calling media access control (MAC) and a physical layer (PHY) in the Ultra Wide Band transport protocol through an alternate medium access control/physical layer (AMP) controller and a protocol adaptation layer (PAL) in the Bluetooth transport protocol; and
transmitting the audio signal of the target audio to the first channel playback apparatus.

### Claim 7 (depends on 5)

The electronic device according to claim 5, wherein the transmitting an audio signal of the target audio to the first channel playback apparatus comprises:
transmitting, when a transmission bandwidth required for transmitting the audio signal of the target audio is greater than a preset bandwidth, the audio signal of the target audio to the first channel playback apparatus through the Ultra Wide Band transport protocol.

### Claim 8 (depends on 7)

The electronic device according to claim 7, wherein the transmitting an audio signal of the target audio to the first channel playback apparatus:
transmitting, when the transmission bandwidth required for transmitting the audio signal of the target audio is less than or equal to the preset bandwidth, the audio signal of the target audio to the first channel playback apparatus or the second channel playback apparatus through the Bluetooth transport protocol.

### Claim 9

A non-transitory computer-readable storage medium, storing a computer program to be executed by a processor of a first electronic device that is connected to a second electronic device through wireless connections, wherein the second electronic device comprises a first channel playback apparatus and a second channel playback apparatus, wherein the computer program, when executed by the processor of the first electronic device, causes the processor to perform operations comprising:
obtaining target audio;
decoding the target audio into a first channel audio signal and a second channel audio signal; and
transmitting an audio signal of the target audio to the first channel playback apparatus through an Ultra Wide Band transport protocol or a Bluetooth transport protocol, wherein the audio signal comprises an indication signal and a combination of the first channel audio signal and the second channel audio signal, wherein the indication signal instructs the first channel playback apparatus to transmit the first channel audio signal to the second channel playback apparatus through the Ultra Wide Band transport protocol.

### Claim 10 (depends on 9)

The non-transitory computer-readable storage medium according to claim 9, wherein the transmitting an audio signal of the target audio to the first channel playback apparatus through an Ultra Wide Band transport protocol comprises:
calling media access control (MAC) and a physical layer (PHY) in the Ultra Wide Band transport protocol through an alternate medium access control/physical layer (AMP) controller and a protocol adaptation layer (PAL) in the Bluetooth transport protocol; and
transmitting the audio signal of the target audio to the first channel playback apparatus.

### Claim 11 (depends on 9)
