Abstract

The invention relates to the technical field of testing devices and discloses a testing device for buzzer production, which solves a problem that the use performance of the existing buzzer testing equipment cannot meet the use requirements. The device comprises a testing box body, wherein a placement opening is formed in the middle of one end of the testing box body, and a sealing door is rotatably mounted in the placement opening; sliding rods are installed on the two sides of a lower portion of an inner cavity of the test box body, a moving block is slidably installed between surfaces of the two sliding rods, a placing plate is fixedly installed at the top of the moving block, a buzzer clamping assembly is installed in the middle of the top of the placing plate, and a heater is installed at the top of the test box body. The testing device for buzzer production has good sealing performance, and can perform decibel detection in the high temperature detection process, effectively ensures accuracy of high temperature detection and decibel detection data, and avoids influence of high temperature and high pitch on detection personnel in the detection process.

Description

technical field [0001] The invention belongs to the technical field of testing devices, in particular to a testing device for buzzer production. Background technique [0002] The buzzer is an electronic sounder with an integrated structure. It is powered by DC voltage and is widely used as a sounding device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, and timers. The buzzer is mainly divided into two types: piezoelectric buzzer and electromagnetic buzzer; the buzzer uses the letter "H" or "HA" in the circuit. [0003] The patent application with notification number CN210513406U discloses a high-temperature sound wave testing device for the production of electromagnetic buzzers, which is heated by heating equipment, and the heat is transported to the inside of the main box by means of a through pipe, a connecting pipe and an air intake pipe, so that the The top and bottom of the buzzer are ...
