Description

Asymmetric horn and loudspeaker

Technical Field

The embodiment of the utility model provides an audio equipment technical field is related to, specificly relate to an asymmetric bugle and loudspeaker.

Background

According to the traditional symmetrical horn, sound wave transmission is carried out in a mode of being symmetrical up and down and left and right in the axis direction, and under the condition of fixed installation, the sound wave is easy to reflect and consume with the surrounding environment in the transmission process, even phase cancellation is caused, and a large amount of energy loss is caused.

SUMMERY OF THE UTILITY MODEL

An embodiment of the utility model provides an asymmetric bugle for solve the problem that traditional type symmetric bugle can cause a large amount of losses of energy.

In order to solve the technical problem, the embodiment of the utility model provides a following technical scheme:

the asymmetric horn comprises a horn body, wherein the upper side wall of the diffusion surface of the horn body is asymmetric with the lower side wall of the diffusion surface of the horn body, and the left side wall of the diffusion surface of the horn body is symmetric with the right side wall of the diffusion surface of the horn body.

Furthermore, the degree of the included angle between the upper side wall of the diffusion surface of the horn body and the horizontal plane is smaller than the degree of the included angle between the lower side wall of the diffusion surface of the horn body and the horizontal plane.

Furthermore, the edge positions of the four sides of the horn body are provided with horn fixing holes.

Further, the horn fixing holes are 4 in number.

The embodiment of the utility model provides a loudspeaker is still provided, including the aforesaid asymmetric bugle, with loudspeaker unit fixed plate and fixed mounting that asymmetric bugle is connected are in loudspeaker unit on the loudspeaker unit fixed plate.

Further, the horn unit fixing plate is in threaded connection with the asymmetric horn.

The embodiment of the utility model provides a beneficial effect who reaches is: the asymmetric bugle in this embodiment can reach the controllable directive purpose of sound wave, reduces the echo interference among the sound propagation process, and then reduces the loss of energy, lets the energy concentrate more and effectively controls audio amplifier loudspeaker cover directive property.

Detailed Description

The preferred embodiments of the present invention will be described hereinafter with reference to the accompanying drawings, and it should be understood that the preferred embodiments described herein are merely for purposes of illustration and explanation, and are not intended to limit the present invention.

As shown in fig. 1-6, an embodiment of the present invention provides an asymmetric horn, including: bugle body 1. The upper side wall 2 of the diffusion surface of the horn body 1 is asymmetric with the lower side wall 3 of the diffusion surface of the horn body 1, and the left side wall 4 of the diffusion surface of the horn body 1 is symmetric with the right side wall 5 of the diffusion surface of the horn body.

In an exemplary embodiment, the angle a between the upper side wall 2 of the diffusing surface of the horn body 1 and the horizontal plane is less than the angle b between the lower side wall 3 of the diffusing surface of the horn body 1 and the horizontal plane, i.e. a < b.

In the present embodiment, the specific number of degrees of the angle a between the upper side wall 2 of the diffusion surface of the horn body 1 and the horizontal plane and the specific number of degrees of the angle b between the lower side wall 3 of the diffusion surface of the horn body 1 and the horizontal plane can be determined by referring to the vertical axis beam simulation parameter diagram shown in fig. 6 according to the directivity required in practice.

In an exemplary embodiment, in order to fix the horn, horn fixing holes 6 are formed at edge positions of four sides of the horn body 1.

In an exemplary embodiment, the number of the horn fixing holes 6 is 4. In other embodiments, the number of the horn fixing holes 6 may be more or less than 4.

In an exemplary embodiment, the asymmetric horn further comprises a horn unit fixing plate 7 connected to the horn body 1. Wherein, the loudspeaker unit fixing plate 7 is used for fixing the loudspeaker unit.

In an exemplary embodiment, the horn unit fixing plate 7 is screwed with the horn body 1.

The utility model provides a theory of operation at asymmetric bugle: the acoustic wave beam is deflected by changing the curvature radius of the upper and lower side walls near the entrance of the horn to generate a diffraction groove, and the directivity angle controlled by the asymmetric horn is larger when the curvature change of the upper and lower side walls is slow and the change span is larger.

The utility model provides an asymmetric bugle, set up to the asymmetry through the last lateral wall with the diffusion face of bugle body and the lower lateral wall of the diffusion face of bugle body, set up the left side wall of the diffusion face of bugle body and the right side wall of the diffusion face of bugle body into the symmetry, thereby can reach the vertical deflection at control driver (loudspeaker unit) beam center and reach the controllable directional purpose of sound wave, reduce the echo interference of sound propagation in-process, and then reduce the loss of energy, let the energy concentrate more and effectively control audio amplifier loudspeaker cover directive property.

The embodiment of the utility model provides a loudspeaker, above-mentioned asymmetric bugle, install loudspeaker unit in the asymmetric bugle.

In an exemplary embodiment, to increase the acoustic efficiency, the driver (horn unit) may be given a configured acoustic impedance.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
