Embodiment Construction
[0031] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0032] The present invention aims at the problem that the sound quality of the audio signal transmitted through the Type-C interface is not up to standard in the prior art, and provides an audio data processing method, which can be applied to terminals, such as figure 1 shown, including:
[0033] Step 11: When it is detected that an external audio playback device is connected to the terminal through a double-sided pluggable interface, and there is audio data to be output, convert the audio data to be output into a digital signal.
[0034] That is, when it is detected that an external audio playback device is plugged into the terminal through the double-sided pluggable interface, if audio data to be output is detected, the output audio data is converted i...

The invention provides an audio data processing method, a terminal and audio outwards-playing equipment. The audio data processing method comprises the steps of converting to-be-output audio data into a digital signal when it is detected that the audio outwards-playing equipment is connected with the terminal through a double-face pluggable port, and the to-be-output audio data exists; sending the digital signal to the audio outwards-playing equipment through a first pin of the double-face socketable port, wherein the first pin is a D+ / D- pin, and the audio outwards-playing equipment can decode the digital signal into an analog signal. According to the audio data processing method, the terminal and the audio outwards-playing equipment, the transmission path of the analog signal can be reduced, and the tone quality is promoted; the problem in the prior art that the audio signal which is transmitted through a Type-C port does not reach the standard in tone quality is well solved.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to an audio data processing method, a terminal and an audio playback device. Background technique [0002] The double-sided pluggable Type-C interface defines the function of audio analog signal transmission, and the audio signal is transmitted through the Type-C interface, which can cancel the 3.5mm headphone jack on the mobile phone; and the multiplexing of this interface can ensure the integrity of the structure And reduce the probability of failure to a certain extent; therefore, it has become a trend for the Type-C interface to replace the 3.5mm headphone jack. [0003] However, in the solution of using the Type-C interface to transmit analog signals, since the analog signals are susceptible to interference during transmission, especially the USB interface is located at the lower end of the mobile phone and is close to the antenna; this makes the sound quality rec...
