Loudspeaker unit, loudspeaking device and orientated sound wave bird driving device

Abstract

The invention discloses a loudspeaker unit, a loudspeaking device and an orientated sound wave bird driving device, wherein the loudspeaking device comprises a mounting base, one or more loudspeaker units, loudspeakers and front reflecting pieces, wherein the one or more loudspeaker units include reflection-type radiators; the loudspeakers are mounted in the cavities of the reflection-type radiators; the front reflecting pieces are arranged in front of the loudspeakers. On the other hand, the orientated sound wave bird driving device comprises a sound source supplying circuit module for generating one or more first bird driving audio signals, an audio processing circuit module for carrying out signal processing on the first bird driving audio signals to obtain a first digital modulated audio data stream, a power processing circuit module for amplifying and filtering the first digital modulated audio data stream and converting the first digital modulated audio data stream into second bird driving audio signals and the loudspeaking device for outputting the second bird driving audio signals. Through the invention, an effect of effectively and remotely driving birds can be achieved.

Description

Speaker unit, speaker device and directional sound wave bird repelling device technical field The invention relates to the field of sound wave generation and application, in particular to a loudspeaker unit, a loudspeaker device and a directional sound wave bird repelling device. Background technique With the enhancement of people's awareness of protecting the environment, loving birds, and protecting birds, the number of birds has increased year by year. At the same time, the scope of human activities has continued to expand, which has greatly reduced the natural environment suitable for birds to live, inhabit, and reproduce. Airports have become birds. An ideal place to live, inhabit and reproduce. Therefore, the incidents of birds endangering flight safety are increasing year by year, causing more and more losses. Once a bird strike occurs, it will cause certain economic losses at least, and the aircraft will be destroyed or even killed. In the existing related techn...
