AI Technical Summary

Problems solved by technology

However, the disadvantages of existing loudspeakers and other ways to generate infrasound are that the infrasound generating device has a large volume and low energy conversion efficiency.
In particular, when infrasound is used in the medical field, existing laboratory infrasound wave generating devices have the problems of large structure, cumbersome use, complex structure, and high cost, and are not suitable for clinical operations.

Abstract

The invention discloses an infrasonic wave generating device driven by a stepping motor, and the device is characterized in that the device comprises a Bluetooth module, an MCU, a stepping motor controller, a stepping motor driver, and a stepping motor infrasonic horn. The intensity of infrasonic waves generated by the device is controlled by changing the advancing distance of the stepping motor or the aperture of a vibrating membrane of the infrasonic horn; the frequency of the generated infrasonic waves is changed by changing the commutation time interval of the stepping motor. The infrasonic wave generating device has the advantages of being simple in working principle, simple in structure, convenient to manufacture, small in size and compact in structure.

Description

technical field [0001] The invention relates to the technical fields of circuits, motors and infrasound, in particular to an infrasonic wave generator driven by a stepping motor. Background technique [0002] Infrasound is a wave below 20Hz that is lower than the low-frequency range of the human ear. Infrasound waves can be used in the medical field. For example, the infrasonic wave 8TM and infrasonic wave 8000 therapeutic instrument developed by CHI Company of the United States can randomly emit infrasound waves below 90dB and are approved by the US FDA. , has various functions such as improving microcirculation, enhancing immunity, reducing inflammation, relieving pain, and sedating and sleeping, and is widely used clinically. For another example, using alpha waves close to brain waves in the infrasound band and music together to generate alpha wave music sound fields, correspondingly providing memory and improving sleep have significant effects. With the deepening of res...
