Abstract

The invention relates to an electronic horn for a motor vehicle or a motor boat. The electronic horn for the motor vehicle or the motor boat comprises a booster circuit, a piezoelectric induction unit, a feedback circuit and a horn unit, wherein the booster circuit is used for carrying out boost processing on input voltage to generate boosted driving voltage, the piezoelectric induction unit is used for receiving the driving voltage generated by the booster circuit to drive a vibrating diaphragm of the horn unit to vibrate so as to give out a sound, and generating induction voltage with the oscillation frequency, the feedback circuit is used for receiving the induction voltage, and building oscillation switch-on and switch-off according to the induction voltage to control the working state of the booster circuit, the horn unit is used for vibrating to give out a sound together with the piezoelectric induction unit when the piezoelectric induction unit is driven by the driving voltage, when operation is carried out, the feedback circuit is controlled by the induction voltage to carry out switch-on and switch-off according to the oscillation frequency, and the booster circuit generates the driving voltage with the oscillation frequency. The electronic horn for the motor vehicle or the motor boat is high in electroacoustic conversion efficiency, improves the energy utilization rate, and is beneficial to energy saving and environmental protection.

Description

technical field [0001] The invention relates to an electroacoustic device, in particular to an electronic horn for motor vehicles and ships. Background technique [0002] The horn is an electroacoustic transducer that converts electrical signals into acoustic signals and spreads them into the air. Since the birth of the automobile in 1886, the car horn has become one of the parts that must be installed on the car. During the driving process of the car, the driver sends out the necessary sound signals according to the needs and regulations to warn pedestrians and attract the attention of other vehicles to ensure traffic safety. [0003] With the development of automobile technology, many parts of automobiles are developing in the direction of electronics, and car horns have also undergone various improvements, and have experienced generations of advancements such as manual, pneumatic, electric, and electronic. In addition to pneumatic horns, whether it is an electromechanic...
