Acoustic testing method for electroacoustic transducer compound antenna module

Abstract

The invention relates to the field of testing, and in particular relates to an acoustic testing method for an electroacoustic transducer compound antenna module. In the prior art, as the electroacoustic transducer compound antenna module is added with a plurality of factor problems such as a sound cavity, a damper and an ultrasonic process in view of a semi-finished product, the analysis of bad problems of the electroacoustic transducer compound antenna module is extremely complex and results in a long period of problem analysis by an engineer. Due to the non-maintainability of the own process of the electroacoustic transducer compound antenna module, all assemblies are discarded as useless in case of a defective product and the production cost can be increased. Hence, the semi-finished product of the electroacoustic transducer compound antenna module is assembled with a sound listening jig for simulating the sound cavity of the electroacoustic transducer compound antenna module, and the obtained product to be tested is capable of simulating the finished product of the electroacoustic transducer compound antenna module; the assembled product to be tested is acoustically tested so that the defective product can be screened out as early as possible; after the screening of the step, the yield of the finished module can be increased and the overall material and labor loss of subsequent processes can be reduced.

Description

technical field [0001] The invention relates to the field of testing, in particular to a method for acoustic testing of an electroacoustic converter composite antenna module. Background technique [0002] An electroacoustic converter is a device that converts sound energy into electrical energy or electrical energy into sound energy. Microphones, loudspeakers and earphones in electroacoustic engineering are the most typical devices that convert electric energy and sound energy, collectively referred to as electroacoustic converters. , also known as electroacoustic transducer. [0003] The current production process of the factory is: each component is combined into an electro-acoustic converter composite antenna module by ultrasonic and dispensing process, and the acoustic performance test and other related performance tests are performed after the electro-acoustic converter composite antenna module is assembled. [0004] The disadvantage of the above-mentioned existing pro...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the above-mentioned existing production process is: because the process of the composite antenna module of the electroacoustic transducer itself is not maintainable, when defective products appear in the composite antenna module of the electroacoustic transducer, it can only be scrapped as a whole, but often Only some small local problems lead to defects, so this kind of scrapping will cause the components of the electro-acoustic converter composite antenna module to be scrapped, and the production cost is seriously wasted.
