Abstract
The utility model relates to a long-distance directional audiphone belonging to a single sensor applying a device with the function of sound reflection, diffraction, directionalism or guidance, particularly a long-distance directional audiphone. The utility model provides the long-distance directional audiphone which can high sensitively collect long-distance sounds from the right front and can greatly weaken the interference of lateral sounds. The utility model is provided with a straight tubular earpiece, wherein one end of the earpiece is an opening end and the other end is a closed end. The inner side surface of the closed end is a parabolic surface, or a spheric surface or an arc surface, a sound pickup or a microphone is arranged at the center or the focal point of the inner side surface of the closed end and the outer side surface of the closed end is provided with an earphone interface which is electrically connected with the sound pickup and the microphone. A sound-absorbing material is arranged on the inner wall of the earpiece, therefore by utilizing the sound-absorbing material on the inner wall of the earpiece to absorb lateral sound waves, the interference that remote forward sound waves receive is reduced. The utility model has the advantages of strong unidirectivity and capability of more clearly monitoring long-distance sounds. The utility model can be applied to monitoring shouts of athletes on football playgrounds, directionally monitoring highway conditions for traffic police, monitoring long-distance sounds for armed police to track, etc.
Description
Technical field
The utility model relates to the single-sensor that a kind of application has sound reflecting, diffraction, orientation or guider, especially a kind of long-range directed audiphone.
Background technology
Usually,, then can be subjected to disturbing, particularly when needing the long-range sound of audiometry, generally all can be flooded and go out in various sound interference from all directions listening if sound is amplified.Notification number provides a kind of sound-conducting apparatus for the patent of invention of CN1089540C, and sound-conducting apparatus has along with the directionality main shaft quadrature of each soniferous element, and at least 3 soniferous elements of the distance configuration of the regulation of being separated by; And to carry out the adder of add operation from the output signal of above-mentioned each soniferous element.Each soniferous element is made of single directionality soniferous element respectively, simultaneously, sound collecting surface with respect to sound source towards same direction, and with roughly uniformly-spaced the configuration.This sound-conducting apparatus can be realized the directionality of the input unit of voice recognition device in the desired acumen of middle register, can collect from positive sound input with high sensitivity, and seldom collect from the noise component(s) of side.
Summary of the invention
The utility model aims to provide a kind of long-range sound from the dead ahead of can collecting with sensitivity, the long-range directed audiphone of the side direction sound interference that can decay significantly.
The utility model is provided with 1 straight tube-like receiver, one end of receiver is an openend, the other end is a blind end, the blind end medial surface is parabolical face or spherical or arcwall face, center or focus place at the blind end medial surface are provided with pick-up or microphone, establish earphone interface at the blind end lateral surface, earphone interface is electrically connected with pick-up or microphone; The receiver inwall is provided with sound-absorbing material.
It is parallel and connect that the utility model can be established many receivers simultaneously.
Said sound-absorbing material can be selected filament or fiber suede etc. for use.
The utility model utilizes the absorption of receiver inwall sound-absorbing material to the side direction sound wave, and the suffered interference of long-range forward sound wave is reduced, and one-way is strong, and more clearly audiometry is to the sound at a distance.The utility model can be applicable to the athletic cry of venues for football audiometry, traffic police to the orientation of road conditions monitor, the People's Armed Police is to the audiometry of following the trail of sound at a distance etc.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1, the utility model is provided with 1 straight tube-like receiver 1, one end of receiver 1 is an openend 11, the other end is a blind end 12, blind end 12 medial surfaces are spherical 13, center at the inboard spherical 13 of blind end is provided with pick-up or microphone 2, establishes earphone interface 3 at the blind end lateral surface, and earphone interface 3 is electrically connected with pick-up or microphone 2; The receiver inwall is provided with sound-absorbing material 4, and sound-absorbing material can be selected filament or fiber suede etc. for use.
Claims (3)
