Test device used for buzzer

Abstract

The invention discloses a test device used for a buzzer. The test device comprises a bracket, a decibel meter, a plurality of thimbles, a test platform, a plurality of vertically-arranged guide rods, a press block and a driving device, wherein the thimbles are electrically connected with a power supply and are used for conducting a buzzer power supply; the test platform is used for bearing a buzzer base plate; the press block is arranged just above the input end of the buzzer power supply; the driving device is used for driving the pressing block to downwards move; the thimbles are arranged into one row to be fixed on a mounting seat; the row of thimbles is correspondingly arranged just below the input end of the buzzer power supply; the upper end of the bracket is provided with a strut used for installing the decibel meter; the upper ends of the guide rods are all fixedly connected with the test platform; the lower ends of the guide rods are in sliding fit in the through hole of the mounting seat; the outer circumstance of each guide rod is sheathed and provided with a spring; one end of the spring is abutted against the test platform; and the other end of the spring is abutted against the mounting seat. The test device used for the buzzer has the advantage of being simple in structure, convenient to operate, safe and reliable.

Description

technical field

[0001] The invention relates to the field of testing devices, in particular to a testing device for buzzers. 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. . Since the buzzer acts as an alarm, it is necessary to test the decibels of the sound it emits before leaving the factory. Existing buzzer tests generally use a hand-held decibel meter or hang the decibel meter at about 20cm directly above the buzzer for testing. Pay attention to the reading on the decibel meter, which is time-consuming and labor-intensive. And because the decibel meter has a distance requirement during the test, it is very inconvenient for the operator to look up at the reading on the display screen of the decibel meter, and beca...
