An integrated device for directional sound propagation with target detection function

Abstract

The invention discloses an integrated voice directional propagation device with a target detection function. The integrated voice directional propagation device comprises a device shell, an ultrasonic transducer, a USB interface, a storage card slot, a switch button, an external audio input interface, a displayer, a detection distance rotary button, a volume rotary button, an audio switching button and an ultrasonic detection directional sounding integrated module, wherein the ultrasonic transducer is arranged on the front side of the device shell, the USB interface, the storage card slot, the switch button and the external audio input interface are arranged on the rear side of the device shell, the displayer, the detection distance rotary button, the volume rotary button and the audio switching button are arranged on the upper side of the device shell, and the ultrasonic detection directional sounding integrated module is arranged in the device shell. The integrated voice directional propagation device integrates the functions of target detection and directional voice propagation, effectively measures the distance, can control the propagated voice volume, does not generate noise interference to other areas, and lowers economic cost for people, and people can conveniently use the integrated voice directional propagation device.

Description

Technical field [0001] The invention belongs to the technical field of ultrasonic detection and high directivity, and specifically relates to an integrated sound directional propagation device with a target detection function. Background technique [0002] In recent years, the noise interference caused by horn devices used in automobiles and exhibition halls has become more and more serious. First of all, with the advent of the automobile age, cars use horn devices to whistle. This kind of horn sound transmission is divergent and has no directional This kind of device does not have the integrated function of detecting pedestrians and then directional sounding in the direction of the pedestrians. Secondly, the horn device used in the exhibition hall cannot automatically interpret specific groups of people in a small area without causing noise interference to other areas. . At present, how to truly realize the integrated sound directional propagation device with target detection f...

[0002] In recent years, the noise interference caused by horn devices used in automobiles and exhibition halls has become increasingly serious. First of all, with the advent of the automobile age, cars use horn devices to whistle. The sound propagation of this horn is divergent and does not have a directional And this kind of device does not have the integrated function of detecting pedestrians and then directional sounding in the direction of pedestrians. Secondly, the horn device used in the exhibition hall cannot automatically explain the work to specific groups of people in a small area without causing noise interference to other areas.
