5VDC 85dB Pin Buzzer application scenarios and pain point solutions

1. Smart Home Devices

Scene: Intelligent Door Lock unlock prompt, intelligent socket power reminder, sweeping robot status feedback.

Pain Point Solution: 5V low-voltage Adapter Battery or USB power supply, 85dB clear sound is not harsh, to avoid disturbing the user's life.

2. Consumer Electronics

Scene: electronic toy sound effect, hand-held thermometer sound, small alarm.

Pain Point Solution: compact size to fit the small interior space, quick response to ensure instant operational feedback, enhanced user interaction experience.

3. Industrial Auxiliary Equipment

Scene: small instrument prompt, equipment running status monitoring.

Pain Point Solution: -10 °C low temperature stable work, to adapt to the complex industrial environment, Pin-type design for rapid installation and maintenance.

Pin Buzzer vs SMD Buzzer

Installation convenience: the Pin-type buzzer uses the pin-straight insertion method, which is convenient for maintenance and replacement, while the ordinary SMD Buzzer needs to be fixed on the circuit board by welding. If it fails, the replacement process is more complicated, it is also more technically demanding.

Voltage Adaptability: Pin-type buzzer such as 5VDC model, can directly adapt to common battery power supply, without additional step-down module; SMD Buzzer Additional buck modules may be required to meet the work requirements, which not only increases the cost, but also takes up board space.

Sound pressure stability: the sound pressure fluctuation of the pin-type buzzer is small, such as the sound pressure fluctuation of the above products is ≤3 db, and the sound is uniform; the sound pressure fluctuation of the ordinary SMD Buzzer is relatively large, generally ≤5 db, a little less steady in the sound.

Application: Pin-type buzzer due to its installation and structural characteristics, more suitable for limited space, frequent maintenance equipment; The ordinary SMD Buzzer is often used in ultra-thin electronic products with strict requirements on the thickness of the circuit board.
