Abstract

The invention discloses an audio playing device and method as well as a mobile terminal. The audio playing device comprises an audio processing chip, an audio amplifier, a loudspeaker and a receiver, wherein a first port of the audio processing chip is connected with an input end of the audio amplifier and the receiver respectively and connected to a speech current amplifier inside the audio processing chip; an output end of the audio amplifier is connected with the loudspeaker. When audio information is transmitted to the audio processing chip, the speech current amplifier inside the audio processing chip transmits the audio information to the audio amplifier through the first port and then transmits the audio information to the loudspeaker for playing after amplifying the audio information, so that the problem that the user experience is affected due to the fact that the volume of earphones increases suddenly is solved. According to the device, all that is required is to connect the audio amplifier and the loudspeaker to a circuit between the first port and the receiver instead of additionally configuring an analog switch and an earphone amplifier, so that the cost is saved.

Description

technical field [0001] The present invention relates to the field of electronic communication, in particular to an audio playback device, method and mobile terminal. Background technique [0002] In daily life, electronic devices, such as computers and mobile phones, are often used to listen to music. Since other people may be disturbed in power amplifier mode, users can use earphones to listen to music. However, when the user listens to music with earphones, other audio information may be received. For example, when listening to music with headphones plugged into the phone's headphone jack, you sometimes receive an incoming call ringtone. see figure 1 The structure diagram of the audio playing device shown in the mobile terminal has an audio processing chip, and the audio processing chip includes a voice current amplifier 1, an earphone left channel current amplifier 2, and an earphone right channel current amplifier 3. In the prior art, the earphone The left channel cur...
