Abstract

The invention discloses a microphone testing device, and relates to the technical field of microphone detection equipment. The microphone detection device comprises an oscillation feeder convenient for conveying microphones, and further comprises a feeding adjustment module convenient for adjusting the placement angle of the microphones and improving the detection efficiency of the microphones; and the screening test mechanism is convenient for detecting and screening different types of microphones. According to the invention, through mutual cooperation of the angle adjusting motor, the turbine, the angle adjusting base, the test module and the image collection element, the device is convenient to adjust the placement angle of the microphone, is convenient to test different types of microphones, avoids manual test of pin type microphones, improves the test efficiency of the microphones, and reduces the cost. And through mutual cooperation of a material jacking air cylinder, a limiting ring, a first sliding way, a second sliding way and a screening guide plate, the device can conveniently screen different types of microphones, the application range of the device is widened, and the device is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of microphone testing equipment, in particular to a microphone testing device. Background technique [0002] The microphone is an energy conversion device that converts sound signals into electrical signals, and is a device that is exactly the opposite of the speaker. The microphone and the speaker are the two terminals of the sound equipment. The microphone is the input terminal, and the speaker is the output terminal. It is usually composed of diaphragm, electret, rear plate, field effect tube and other components. The microphone is connected to the outside The method can be divided into: solder point microphone and pin microphone. [0003] After the microphone is manufactured, in order to ensure the quality of the product, it is usually necessary to use a test device to perform various performance tests on the microphone such as sensitivity test, background noise test, signal-to-noise ratio test and low-...
