Abstract
The utility model relates to a long distance sound wave controller. The long distance sound wave controller includes a housing and an audio frequency generation device disposed in the housing. The audio frequency generation device mainly includes a digital signal processing module, a power amplification module and an energy transducer module. A taper-shaped resonator is disposed between the audio frequency generation device and the front end of the housing. The conical degree of the resonator is adjustable. A space between the audio frequency generation device and the front end of the housing is adjustable. The adjustable resonator is formed between the audio frequency generation device and the front cover of the housing, such that the vibration at the lowest resonant frequency can be converted in a highly efficient manner to be discomposed into the relatively low-intensity resonance in two frequency ranges at the lowest resonant frequency. A hearing sound is made in the minimum resonant frequency to form a sound wave cluster angle, thereby achieving optimum focusing, orientation and penetrating effects. The resonator is adjusted according to the needs, and therefore, the emission direction is adjusted in a certain extent. The scope adjustment is more convenient.

Utility model content
The technical problems to be solved in the utility model is: the angle that overcomes the audio emission direction of prior art medium and long distance sound wave controlled device is fixed, and the technical matters that can not adjust according to actual conditions provides a kind of remote sound wave controlled device.
The utility model solves the technical scheme that its technical matters adopts: a kind of remote sound wave controlled device, comprise housing and be arranged on the audio frequency generating means in housing, described audio frequency generating means mainly comprises digital signal processing module, power amplifier module and transducer module, it is characterized in that: between described audio frequency generating means and the front end of housing, there is tapered resonant cavity, the tapering of described resonant cavity is adjustable, spacing between audio frequency generating means and the front end of housing is adjustable, can the angle of the transmit direction of sound wave be changed by adjusting, to meet actual use needs.
Further, described resonant cavity is elastic cavity, the big opening end of described resonant cavity is fixedly connected on housing, the osculum end of resonant cavity is connected on the transducer of audio frequency generating means, and described housing is provided with pull bar that audio frequency generating means is moved along housing fore-and-aft direction and the clip of steady brace.Regulate the spacing of audio frequency generating means and housing front end by pull bar, thereby regulate the angle of acoustic emission direction.
Further, for ease of audio frequency generating means mobile adjusting in housing, be provided with the guide pole that at least one be arranged in parallel in described housing, described audio frequency generating means is provided with the orienting sleeve matching with guide pole.
Have, the quantity of described guide pole is two.
For reducing the divergence of sound wave to surrounding, reduce the impact on operating personnel, the front end of described housing is provided with the back-up ring of adjustable-angle.
The beneficial effects of the utility model are: remote sound wave controlled device of the present utility model arranges an adjustable resonant cavity between audio frequency generating means and the protecgulum of housing, vibration Efficient Conversion in addition like this can be by lowest resonant frequency time, make it to be decomposed in upper and lower two frequency ranges of this frequency compared with the resonance of small intensity, make to send audible sounds under MIN resonance frequency, form acoustic wave bundle angle, realize best focusing, orientation is penetrated effect with wearing, resonant cavity can regulate as required, thereby transmit direction is regulated within the specific limits, sensing scope is adjusted more convenient.
