Abstract

The invention relates to ultrasonic equipment and aims at providing an ultrasonic transducer with a quantitative amplitude feedback system. An amplitude detector is embedded in the transducer. The amplitude detector comprises a voltage generating piece, a rectifying circuit, an acceleration sensor, a storage circuit and a wireless transmitting circuit which are sequentially connected through a wire, or comprises a wireless receiving and transmitting circuit, a rectifying circuit, an acceleration sensor and a storage circuit which are sequentially connected through a wire. According to the ultrasonic transducer, a battery is not arranged, and power generation and power supply can be achieved automatically; the acceleration sensor is used for directly measuring the amplitude, and the amplitude can be accurately calibrated; the amplitude and frequency signals are transmitted wirelessly, use of an external wire is avoided, and the equipment is more convenient to use; both the absolute value and the relative value of the amplitude can be given, and monitoring is facilitated; and by cooperation use of the transducer and a driving power source storage chip, matched original parameters can be stored. Alarming can be carried out immediately if the matched parameters given by a power source are not right, and thus technological parameters can be conveniently controlled.

Description

technical field [0001] The present invention relates to ultrasonic equipment, in particular to ultrasonic transducers with quantitative amplitude feedback systems. Background technique [0002] In the existing ultrasonic transmission system, the core components are the driving power supply and the transducer. Its working principle is: the driving power supply sends out high-frequency high-power excitation current, and drives the transducer to vibrate and emit ultrasonic waves. The transducer either directly emits ultrasonic waves, or pushes the horn, the emitter head, and finally the emitter head emits ultrasonic waves. It is the amplitude of the emitting head that determines the intensity of ultrasonic emission. The larger the amplitude, the stronger the ultrasound. The greater the current flowing through the transducer, or the higher the excitation voltage applied to the transducer, the stronger the vibration of the transducer and the greater the amplitude. [0003] In...
