[0002] At present, conventional mobile phones have the function of playing music. Therefore, many music lovers store their favorite music in the mobile phone, but due to the limitation of mobile phone design, usually, the sound effect of the loudspeaker on the mobile phone is not as good as that of the audio equipment.

In order to utilize the audio equipment to play the music stored in the mobile phone, the existing method is to connect the mobile phone to the audio equipment through the connection interface on the audio equipment, so as to realize the use of the audio equipment to play the music in the mobile phone. Connected to an audio device, the user cannot use the mobile phone to do other things while listening to music, and when the user needs to answer the call, the user has to disconnect the phone from the audio device

[0003] Of course, with the development of Bluetooth technology, many mobile phones have Bluetooth transmitter modules, and Bluetooth audio equipment is also very common. By establishing a Bluetooth wireless connection between mobile phones and Bluetooth audio equipment, Bluetooth audio equipment can be used to play music in mobile phones, but Bluetooth transmission There is a certain limit to the distance. Usually, in order to ensure the smoothness of the Bluetooth audio device playing the music in the mobile phone, the mobile phone cannot be too far away from the Bluetooth audio device.
