Abstract
The utility model discloses a novel horn which sequentially comprises a baseplate, an expanding part and an opening. The opening takes the shape of a regular octagon frame and is parallel with the baseplate; the center line of the baseplate and that of the opening are in the same straight line; a central hole is formed on the baseplate; and the expanding part comprises eight identical exponential type curved surfaces with side edges sequentially connected, further one end of each exponential type curved surface is connected with the central hole and the other end is connected with one side edge of the opening. Since the regular octagon opening is adopted in the novel horn, and the eight exponential type curved surfaces are arranged, both frequency response and directive control are considered, performance characteristics of both square horn and round horn are integrated, directive control and smooth response curve are reasonably combined, and sound field and timbre are unified and in harmony, thereby improving the quality of the horn and obtaining better tone quality effect.
Description
Technical field
The utility model relates to the acoustic product field, particularly a kind of novel bugle that combines the performance characteristics of square and circular bugle.
Background technology
In the prior art, bugle amplifies product as sound, is generally used in the public address equipments such as audio amplifier, loudspeaker.General bugle all has the enlarging section of a taper, and this enlarging section is conical usually.During work, sound wave passes through from the enlarging section, thereby makes in the sound set, makes it can propagate into farther place.Bugle is to the quality of whole public address equipment to the sound tonequality of external diffusion, and distortion etc. has a very important role.So in the acoustic product manufacturing industry, the design developer of bugle is also constantly improveing the structure of bugle,, thereby obtain better acoustical quality in the hope of the quality of raising bugle.
The utility model content
The purpose of this utility model is, a kind of novel bugle reasonable in design is provided, this novel bugle adopts the octagon opening, be provided with eight exponential curved surfaces, take into account frequency response and directive property control, combine the performance characteristics of square and circular bugle, the reasonable combination of the control of realization directive property and level and smooth response curve constitutes the harmony of sound field and tone color.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of novel bugle, it comprises substrate, enlarging section and opening successively, described opening is an octagon frame shape, this opening is parallel with substrate, and the center line of this substrate and opening is on same straight line, and this substrate is provided with center pit, and the exponential curved surface that described enlarging section is identical by eight and side links to each other is successively formed, described exponential curved surface one end is connected with center pit, and the other end of this exponential type curved surface is connected with a side of opening.
As further improvement of the utility model, be cylindric between the outer peripheral face bottom of described enlarging section and the substrate.
As further improvement of the utility model, rounded, square or other regular polygons of described substrate.
As further improvement of the utility model, be respectively equipped with one in described octagon opening two adjacent side intersections and be convenient to this novel bugle and be fixed to through hole on other objects.
As further improvement of the utility model, this novel bugle is formed in one.
The beneficial effects of the utility model are: the utility model adopts the octagon opening, be provided with eight exponential curved surfaces, take into account frequency response and directive property control, combine the performance characteristics of square and circular bugle, the reasonable combination of the control of realization directive property and level and smooth response curve, constitute the harmony of sound field and tone color, thereby can improve the quality of bugle, obtain better acoustical quality.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.

Embodiment
Embodiment: see Fig. 1, Fig. 2 and Fig. 3, a kind of novel bugle of the utility model, it comprises substrate 1, enlarging section 2 and opening 3 successively, described opening 3 is an octagon frame shape, this opening 3 is parallel with substrate 1, and the center line of this substrate 1 and opening 3 is on same straight line, this substrate 1 is provided with center pit 11, the exponential curved surface 21 that described enlarging section 2 is identical by eight and side links to each other is successively formed, described exponential curved surface 21 1 ends are connected with center pit 11, and the other end of this exponential type curved surface is connected with a side of opening 3.
Be cylindric 12 between the outer peripheral face bottom of described enlarging section 2 and the substrate 1.
Described substrate 1 rounded, square or other regular polygons.
Be respectively equipped with one is convenient to this novel bugle and is fixed to through hole 31 on other objects in 3 liang of adjacent sides of described octagon opening intersection.
In the present embodiment, this novel bugle is formed in one.
The utility model adopts octagon opening 3, be provided with eight exponential curved surfaces 21, take into account frequency response and directive property control, combine the performance characteristics of square and circular bugle, the reasonable combination of the control of realization directive property and level and smooth response curve, constitute the harmony of sound field and tone color, sound can propagate fartherly, and tonequality is better via the center pit on the substrate 1 11, enlarging section 2 and opening 3 spread outs.
As described in the utility model embodiment, with other novel bugles of the same or similar structure of the utility model, all in the utility model protection domain.
