Abstract

The invention belongs to the technical field of detection methods, and particularly relates to a method for detecting the dustproof property of an electroacoustic transducer of communication terminal equipment. The method comprises the following steps: testing the magnetic flux F1 of the electroacoustic transducer by a gauss meter; putting scrap irons with the particle size of 100-400 meshes into a box body, arranging the communication terminal equipment into the box body to vibrate the box body under the frequency of 5-100HZ for 10min-5h; taking out the communication terminal equipment, removing the scrap irons from the surface of the communication terminal equipment, testing a magnetic flux F2 of the electroacoustic transducer by the gauss meter, comparing F2 with F1, and estimating the dustproof property of the electroacoustic transducer. Compared with the prior art, the method disclosed by the invention has the advantages that the dustproof property of the electroacoustic transducer can be well tested and is adjusted and improved, so that the phenomena of cracking voice, hoarseness, noise, volume down, sand particle entering and the like can be reduced, and the confidence level of a user is increased.

Description

technical field [0001] The invention belongs to the technical field of detection methods, and in particular relates to a method for detecting the dustproof performance of an electroacoustic transducer device of a communication terminal device. Background technique [0002] Electroacoustic transducers are devices that convert electrical (acoustic) signal energy into corresponding acoustic (electrical) signal energy, including speakers, receivers, and microphones. Among them, the speaker, also known as "horn", is a transducer element that converts electrical signals into acoustic signals, and it can be seen in electronic and electrical equipment that emits sound. A receiver, also called a handset, is an electro-acoustic device that converts audio electrical signals into sound signals. It is widely used in communication terminal equipment such as mobile phones, fixed phones, and hearing aids to realize audio (voice, music) playback. [0003] In order to avoid the influence of ...
