1.  Description

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, timers and other electronic products . The buzzer is mainly divided into two types of piezoelectric buzzer and electromagnetic buzzer. The buzzer is represented by the letter "H" or "HA" in the circuit (the old standard is "FM", "ZZG", "LB", "JD", etc.).

Note: (1) After the product passes through the reflow soldering machine, all electrical properties should be kept within the
specifications.
(2) The operating temperature of reflow soldering must be within the recommended range. If it exceeds the range, it may affect the performance of the product.

Reliability test

After any of the following tests, the following standards must be met. The appearance and electrical performance (except for sound pressure) must not have any defects or attenuation, and the sound pressure cannot be less than 10dB of the minimum sound pressure in the specification.
6.1 Life test
Place the test piece at a temperature of 25 ± 10 ° C and input a resonance frequency square wave with a rated voltage and a duty ratio of 1/2 to test for 96 hours.
6.2 High temperature test
The test piece was stored at + 80 ° C for 96 hours, taken out and placed at normal temperature for 3 hours, and then tested.
6.3 Low temperature test
The test piece is stored at a temperature of -30 ° C for 96 hours, taken out and placed at normal temperature for 3 hours, and then tested.
6.4 Humidity test
Put the test piece under the condition of temperature + 40 ± 3 ℃ and humidity 90% ~ 95% for 48 hours, then put it at room temperature for 3 hours and then test.
6.5 Temperature shock test
Put the test piece under the following temperature change conditions: 60 ℃ 1 hour → 25 ℃ 3 hours → -20 ℃ 1 hour → 25 ℃ 3 hours (1 cycle), after completing a cycle experiment, continue after 1 hour One experiment, the total number of test cycles: 10 cycles.
6.6 Floor test
After standard packaging of the test piece (3 sides and 6 sides of the box), it falls from a height of 75 cm onto a thick wooden board or a 5 cm thick hard board
6.7 Mechanical vibration test
Test again after the experiment under the following conditions: vibration speed: 1000 times / min; amplitude: 1.5 mm; time: 1 hour to change the direction of one degree of freedom for a total of 3 degrees of freedom.
note:
It is necessary to avoid irrelevant materials from entering the product, such as magnetic materials, water-soluble materials, corrosive gases, etc. Because these irrelevant materials will affect the electrical performance of the product.
