Embodiment Construction

[0035] The present invention provides a method and system for detecting that the sound inlet hole of a microphone is blocked. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] See figure 1 , figure 1 It is a flowchart of a preferred embodiment of a method for detecting that a microphone sound inlet is blocked in the present invention, and the method specifically includes steps:

[0037] S1. The smart terminal stores the voice signal of the preset duration sent by the user to it, and detects the high-frequency cut-off point Fh' of the voice signal;

[0038] S2. Calculate the absolute value of the difference between the high-frequency cut-off point Fh' and the preset standard high-frequency cut-off ...

Abstract

The invention provides a method and system for detecting the blocking of microphone sound holes. The method comprises the steps that an intelligent terminal storage user issues a voice signal with a preset time length, and detects the high frequency cut-off point Fh' of the voice signal; the absolute value of the difference between the high frequency cut-off point Fh' and the preset standard high frequency cut-off point Fh, and the case whether or not the absolute value of the difference is greater than the preset difference threshold value DeltaF is evaluated; when the absolute value of the difference is greater than the preset difference threshold value DeltaF, the user is reminded that the sound hole of the microphone is blocked. The method is simple and convenient, can detect in real time whether or not the sound test holes of the microphone in the intelligent terminal are blocked, to make it easy for users to find the problem that the sound holes of the microphone are blocked, and avoid the poor call quality disturbances and inconveniences caused by the described problems.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and system for detecting that a sound inlet hole of a microphone is blocked. Background technique [0002] The microphone acts as a microphone on the smart terminal. The voice signal sent by the user enters the microphone sound inlet on the smart terminal, is collected by the microphone and sent to the other party, so that the other party hears the sound. However, in some cases, the sound inlet of the microphone may be blocked, resulting in poor call quality. For example, improper holding posture will block the sound inlet of the microphone; or when the smart terminal is placed on the blanket randomly during the hands-free call, the sound inlet is blocked by the blanket; or the sound inlet of the microphone is blocked by dust and foreign objects, and is stuck by a transparent sticker wait. The blocking of the sound inlet hole of the above-mentioned microp...
