Audio processing and output circuit in mobile terminal

Abstract

The invention provides an audio processing and output circuit in a mobile terminal. The audio processing and output circuit is characterized by comprising an audio output circuit, a power amplification circuit and an audio signal processing circuit; the input end of the power amplification circuit is connected with the output end of the audio signal processing circuit; the output end of the power amplification circuit is connected with the input end of the audio output circuit; the audio signal processing circuit comprises a first audio signal processing circuit body and a second audio signal processing circuit body, and both the output end of the first audio signal processing circuit body and the output end of the second audio signal processing circuit body are in circuit connection with the input end of the power amplification circuit. The circuit is simple in structure, small in size and convenient for users to use.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an audio processing and output circuit in a mobile terminal. Background technique [0002] With the rapid development of electronic communication technology, mobile phones have become an indispensable tool in people's daily life. With the diversification of mobile phone brands and functions, the competition in the mobile phone market is becoming more and more fierce. Lower manufacturing costs, excellent performance and rich functions can enable mobile phone companies to have a higher market competitive advantage. In the prior art, in order to reduce the manufacturing cost of the mobile phone, a three-in-one audio device is often used to realize the functions of the speaker, earpiece and motor of the mobile phone. However, since the audio input circuit of the three-in-one device in the prior art only produces a single waveform, the use of the three-in-one device in the ...

Problems solved by technology

However, since the audio input circuit of the three-in-one device in the prior art only produces a single waveform, the use of the three-in-one device in the prior art cannot simultaneously realize the functions of the loudspeaker, receiver and motor, and can only be used in the above three functions. to switch

In this way, when a user receives an incoming call, he can only choose to output a ring tone or a separate motor vibration to prompt for answering, instead of using the mode of developing vibration while outputting the ring tone to prompt for answering, which reduces the ease of use of the mobile phone
