Problems solved by technology

[0003] For multimedia devices with a single MIC, theoretically, the single MIC should be connected to the Tx1 audio channel. At this time, the ADSP processor does not need to perform an echo cancellation operation on the audio signal. However, due to the hardware connection, there may be a single MIC connected to the auxiliary audio channel. In this case, the audio signal collected by the MIC will be sent to the auxiliary audio channel, while the main audio channel has no audio signal transmission, so that there is no signal input to the signal receiving port of the ADSP processor. According to the internal logic of the ADSP processor, it is impossible to reference The audio signal received by the receiving end is transmitted, so that the audio signal cannot be transmitted to the receiving end, which reduces the user experience

Abstract

The present application discloses an audio channel switching device, which is applied to electronic equipment. The electronic device includes a processor, a main audio channel, an auxiliary audio channel, and an audio acquisition device. The main audio channel is connected to a signal input port of the processor. The audio channel The switching device includes: a monitoring device, configured to switch the audio signal to the main audio channel for transmission when monitoring the presence of an audio signal in the auxiliary audio channel, so that the processor transmits the audio signal received by the signal input port to the receiver; wherein the audio signal is transmitted to the receiver; The signal is the audio signal collected by the audio collection device. The present application can ensure that the audio signal collected by the single-audio collection device is transmitted to the receiver, thereby improving the user experience. The present application also discloses an audio channel switching method, device and electronic device, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of multimedia equipment, and in particular, to an audio channel switching device, method, device and electronic device. Background technique [0002] Now many multimedia devices, the ALSA (Advanced Linux SoundArchitecture, Advanced Linux Sound Architecture) Audio audio input system of the communication chip platform supports two-channel (including Tx1 audio channel and Tx2 audio channel) stereo by default. Generally, for a dual-MIC multimedia device, one MIC is connected to the Tx1 audio channel, and the other MIC is connected to the Tx2 audio channel. , the Tx1 audio channel is used as the main audio channel and is connected to the signal receiving port of the ADSP (Advanced Digital Signal Processor) processor. The ADSP processor performs processing on the audio signal received by the signal receiving end according to the preset processing logic. Process and transmit the processed audio signal to the recei...
