Abstract

The invention provides a high sound pressure alarm buzzer which comprises a buzzer and a control circuit. The control circuit comprises 11 resistors, 6 electrolytic capacitors, 6 triodes, a diode and a transformer. The high sound pressure alarm buzzer provided by the invention has the advantages of high sound pressure level, rushed sound, strong sense of urgency, small volume and light weight, and is applicable to all kinds of alarm situations. The stability and the safety of a device are improved.

Description

Technical field [0001] The invention relates to an alarm buzzer, in particular to a high sound pressure alarm buzzer. Background technique [0002] At present, the existing alarm buzzer is limited in size and cannot provide high sound pressure. It is not suitable for some specific occasions, such as anti-theft, fire prevention, gas leakage, emergency rescue, call for help, and strong reminders. Sound equipment, etc., cause the person who needs to be reminded to be unable to hear the prompt sound, and then unable to take due protective measures, causing losses. Therefore, develop a small size and high sound pressure. An alarm buzzer with a stable circuit is particularly important. Summary of the invention [0003] The purpose of the present invention is to provide a high sound pressure alarm buzzer, which solves the problem that the alarm buzzer cannot emit high sound pressure. [0004] The present invention provides a high sound pressure alarm buzzer, including a buzzer and a con...
