Embodiment 1

[0045] see figure 1 , figure 1 It is a schematic flowchart of an audio channel detection method provided in this embodiment. Such as figure 1 As shown, this audio channel detection method is applied to user equipment, including the following steps:

[0046] S101. Control the pressure field microphone of the user equipment to output audio, and the audio is transmitted through the audio channel to be detected.

[0047] In this embodiment, the pressure field microphone may be a built-in device in the user equipment.

[0048] In this embodiment, the pressure field microphone can be a device or device associated with the user equipment, because it is associated with the user equipment, and the audio channel in the user equipment is the object to be detected, so the pressure field microphone can be understood as belonging to the user equipment a device. Similarly, the microphone may also be a device that belongs to the user equipment but is not set in the user equipment.

Embodiment 2

[0076] see figure 2 , figure 2 It is a schematic flowchart of an audio channel detection method provided by an embodiment of the present invention. Such as figure 2 As shown, the detection method of the audio channel includes the following steps:

[0077] S201. Control the pressure field moving iron microphone of the user equipment to output audio, and the audio is transmitted through the audio channel to be detected.

[0078] In this embodiment, the pressure field moving iron microphone is a moving iron type pressure field microphone, and the moving iron type microphone is a microphone that is transmitted to the center point of a diaphragm through a connecting rod with a precise structure, so as to generate vibration and sound. In essence, the moving iron microphone uses an electromagnet to generate an alternating magnetic field. The vibration part is an iron piece suspended in front of the electromagnet. When the signal passes through the electromagnet, the magnetic fi...

Embodiment 3

[0103] see image 3 , image 3 It is a schematic structural diagram of an audio channel detection device provided by an embodiment of the present invention.

[0104] Such as image 3 As shown, the audio channel detection device 300 is applied to user equipment, including:

[0105] The control module 301 is configured to control the pressure field microphone of the user equipment to output audio, and when a receiving instruction is detected, control the microphone of the user equipment to receive audio; wherein the audio is transmitted through the audio channel to be detected.

[0106] In this embodiment, the pressure field microphone can be set in the user equipment, and the microphone can also be set in the user equipment; at the same time, both the pressure field microphone and the microphone can also be set in the user equipment, but belong to It is specific to the user equipment, and can make the pressure field microphone, audio channel and microphone form an external s...

Abstract

The invention provides a detection method for an audio channel, which is applied to user equipment. The method includes the following steps: controlling a pressure field microphone of the user equipment to output audio frequency, and transmitting the audio frequency through a to-be-detected audio channel; controlling a transmitter of the user equipment to receive the audio frequency, and processing the received audio frequency to obtain measurement frequency response information; and comparing the measurement frequency response information with preset frequency response information to obtain adetection result, and determining whether the audio channel of the user equipment has a leakage according to the detection result. Therefore, the detection method and device for the audio channel provided by embodiments of the invention can simply, quickly, and accurately detect the audio channel, thereby avoiding a situation of the occurrence of a problem in the audio channel when manufacturingof a mobile phone is completed.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to a method and device for detecting an audio channel. Background technique [0002] At present, with the development of society, mobile phones are constantly improving their functions or improving their appearance. However, in the process of continuous improvement, mobile phones will still include the middle frame, battery, various original devices and display screens. Among them, the middle frame is the basic frame of the mobile phone, and its production requirements are usually relatively high. [0003] With the demand for waterproof performance, when focusing on waterproof mobile phones, the production of the middle frame is usually given priority, because once the middle frame is cracked or damaged, it will affect the use of waterproof mobile phones. Among them, the audio channel included as the middle frame is particularly easy to be damaged, so the leak...
