Abstract

The invention discloses an acoustic testing device which comprises a fixed bracket, and a lug and an artificial mouth fixedly arranged on the fixed bracket, wherein an installation groove for arranging an artificial ear is formed in the lug; a sound emitting hole is formed in the artificial mouth; and a terminal fixing assembly for fixing a to-be-detected terminal is arranged on the fixed bracket. The acoustic testing device comprises the fixed bracket, and the lug and the artificial mouth arranged on the fixed bracket; the installation groove for arranging the artificial ear is formed in the lug; the terminal fixing assembly is arranged on the fixed bracket; the fixed bracket plays a support connection role; and the terminal fixing assembly plays a role in fixedly arranging the to-be-detected terminal. The acoustic testing device has the advantages of being simple in structure, low in fabrication cost, convenient to operate and high in testing efficiency.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to an acoustic testing device. Background technique [0002] With the continuous development of science and technology, the mobile terminal is changing from a simple communication tool to a comprehensive information processing platform, gradually becoming an indispensable necessity in people's daily life. When testing the performance of a finished product of a mobile terminal, its sound emitting performance and sound receiving performance are one of the important criteria for measuring whether the production quality of the mobile terminal is qualified. [0003] At present, when testing the sound performance of mobile terminal products, its testing system includes a head and shoulders simulator and a mobile terminal testing device. Among them, the head and shoulders simulator, for example, the application number is "201020211216.X" and the name is "a head and shoulders simu...
