Problems solved by technology

[0004] Since each manufacturer independently develops the audio equipment based on the traffic earphone, it seldom considers compatibility with other manufacturers' expansion equipment, which leads to smart devices needing to load the drivers based on the traffic earphone interface of different manufacturers, and the communication of the traffic earphone interface is different from that of USB, etc. For other interfaces, it can confirm that the driver and the audio device match only through the communication between the loaded driver and the audio device. When there are a large number of audio device drivers in the smart device, the polling time of the smart device will be longer

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] see figure 1 As shown, the embodiment of the present invention provides a method for identifying an audio device, including the following steps:

[0030] S1: Plug the audio device into the earphone interface of the smart device; preset the designated time in the smart device, and the designated time is 200ms; preset the first designated time, the second designated time and the third designated time in the audio device , the first specified time, the second specified time and the third specified time are all 20ms.

[0031] S2: The smart device sends a square wave with a fixed frequency of 200ms to the audio device, and the fixed frequency does not exceed 44.1KHz.

[0032] S3: The smart device judges whether the audio device receives the fixed frequency square wave, if not, re-execute step S2, otherwise go to step S4.

Abstract

The invention discloses an audio device recognition method and system, and relates to the field of mobile terminal devices. The method includes the following steps that an intelligent device sends square waves with the fixed frequency to an audio device in the preset time period; the audio device receives the square waves with the fixed frequency and then conducts binary coding on an audio device number, bit separators are set between every two adjacent bits in the binary coding process, the binary codes provided with the bit separators are converted into variable-frequency square waves, and the variable-frequency square waves are sent to the intelligent device; the intelligent device decodes the variable-frequency square waves according to the variable-frequency square wave frequency rule after receiving the variable-frequency square waves, the audio device number is obtained, and an audio device driver corresponding to the audio device number is loaded according to the audio device number. By means of the audio device recognition method and system, the time spent on training the intelligent device in a rotation mode is reduced, and the loading speed of the audio device driver is increased.

Description

technical field [0001] The present invention relates to the field of mobile terminal equipment, in particular to an identification method and system for audio equipment. Background technique [0002] The rapid development of the information age has made smart devices more and more widely used, among which more representative devices such as smart phones and tablet computers have become necessary supplies for people's daily use. [0003] With the wide application of smart devices, the expansion devices with their interfaces have also developed rapidly. At present, the expansion interfaces available for the smart device mainly include a USB (Universal Serial Bus, Universal Serial Bus) interface, a Bluetooth interface, a traffic earphone interface, and the like. Among them, the traffic earphone interface can transmit data signals instead of only transmitting audio signals before, making it widely used as a new expansion interface. Various manufacturers have launched audio equ...
