Description

A kind of sound body with Horn

Technical field

The utility model is related to a kind of sound equipment, more particularly to a kind of sound box bodies with Horn.

Background technology

In recent years, the bugle of linear array speaker high-pitched speaker is widely used in Specialty Hi-Fi, and sound wave shakes from smaller Film diameter aditus laryngis, a number mouth are radiated space, due to horn sectional area variation it is irregular, wave surface during gradually changing, The uneven frequency characteristic that will also influence loud speaker of radiation impedance, the area of bugle opening, influencing to write the bugle can produce Raw low-limit frequency cut off.Accordingly, it is determined that the shape of bugle forms it into pure resistance state and holds the resonance of horn to resetting Sound quality is particularly important.If bugle designs unreasonable, may be decreased the efficiency of high-pitched speaker, frequency response, diffusion wave mode, The factors such as diffusion angle, sensitivity all can be generated poor audio by serious influence.

Utility model content

The shortcomings that the purpose of the utility model is to overcome the prior arts and deficiency provide one kind and passing through hyperbolic surface launching song The bugle that face is formed reflects high frequency and is coupled with bass, to reach the sound body that clarity is more reinforced.

The purpose of this utility model is achieved through the following technical solutions：A kind of sound body with Horn, including case Body, subwoofer mounting hole and it is arranged in the high-pitched speaker installation position of box house, the front of the high-pitched speaker installation position is pacified Equipped with Horn, the Horn includes symmetrical and tilts installation：First bugle and the second bugle, described first Bugle, the second bugle shape all be outwardly convex arc-shaped curved surface, surrounded between the first bugle and the second bugle outward The cone space opened is equipped with the sound outlet channel of high-pitched speaker between the first bugle and the second bugle.

Preferably, first bugle and the second bugle are all fixed on by birch wood on babinet.

Preferably, the top of the box is equipped with connecting groove.

Preferably, the cross-sectional shape of the babinet is trapezoidal.

Preferably, the babinet both sides are equipped with carrying groove.

Preferably, the apex angle of the cone space is obtuse angle.

Preferably, the outermost end protrusion casing end face of first bugle, the second bugle.

The utility model has the following advantages compared with the existing technology and effect：High-frequency sound is by the first bugle, the After the reflection of two bugles, the reflective wave source of hyperboloid is formed, the reflective wave source of the hyperboloid controls refractive technique, energy by high frequency Cohesion is coupled well together with bass, the coherent medium-high frequency energy being horizontally or vertically arranged, and generate accurate and predictable Result.The reflective wave source of hyperboloid creates a virtual acoustic wave being located at except loudspeaker acoustic enclosure with acoustic reflection minute surface Source, its true sound source (high-pitched speaker) substantially any local and virtual sound source can then be located at the speaker back of the body inside speaker Afterwards, the measurement of wave source is made to show the correspondence of height between mathematical prediction and legitimate reading.

Description of the drawings

Fig. 2 is the internal structure chart of the utility model.

Specific implementation mode

The present invention will be further described in detail with reference to the embodiments and the accompanying drawings, but the implementation of the utility model Mode is without being limited thereto.

According to Fig. 1 and a kind of sound body with Horn shown in Fig. 2, including babinet 1, subwoofer mounting hole 2 with And the high-pitched speaker installation position 3 being arranged inside babinet 1, the front of the high-pitched speaker installation position 3 are equipped with Horn 4, The Horn 4 includes symmetrical and tilts installation：First bugle 41 and the second bugle 42, first bugle 41, The shape of second bugle 42 is all the arc-shaped curved surface of outwardly convex, surrounds between the first bugle 41 and the second bugle 42 and opens outward The cone space 43 opened is equipped with the sound outlet channel 44 of high-pitched speaker between the first bugle 41 and the second bugle 42.High-frequency sound passes through First bugle 41 and the second bugle 42 form the reflective wave source of hyperboloid, and the reflective wave source of the hyperboloid is controlled by high frequency and reflected Technology can couple cohesion well together with bass, the coherent medium-high frequency energy being horizontally or vertically arranged, and generate it is accurate and Predictable result.The reflective wave source of hyperboloid, with acoustic reflection minute surface, establishment one is located at virtual except loudspeaker acoustic enclosure Acoustics wave source, its true sound source (high-pitched speaker) can be substantially any local inside speaker and virtual sound source is then located at Speaker behind, makes the measurement of wave source show the correspondence of height between mathematical prediction and legitimate reading.

Most prominent advantage, is not break in sound and dramatically reduces multiple spot in the case of the coupling of element The time difference of sound source and the interference of phase improve the clarity and transparent feel of sound, so that linear array speaker can be used as very Positive line source provides smooth phase response and broader coverage area, and under all frequencies without any canceling sound or Loudspeaker high frequency directive property is interfered, so that the region sound that high-pitched speaker projects more is concentrated, is clear, more efficient, acoustic pressure bigger passes It obtains farther.It is assemblied in the structure babinet of the Horn and babinet unitary design for its special linear array speaker, appropriate mix Subwoofer detection debugging after, enhance the comprehensive performance of whole money speaker products.

In the present embodiment, first bugle, 41 and second bugle 42 is all fixed on by birch wood 5 on babinet.

Preferably, 1 top of the babinet is equipped with connecting groove 6.

Preferably, the cross-sectional shape of the babinet 1 is trapezoidal.

Preferably, 1 both sides of the babinet are equipped with carrying groove 7.

Preferably, the apex angle of the cone space 43 is obtuse angle, to make Horn 4 have broader spread scope.

Preferably, in order to keep the propagation distance of Horn 4 farther, first bugle 41, the second bugle 42 it is outermost End 1 end face of protrusion babinet.

Above-described embodiment is the preferable embodiment of the utility model, but the embodiment of the utility model is not by above-mentioned The limitation of embodiment, under other any Spirit Essences and principle without departing from the utility model made by change, modify, replace In generation, simplifies combination, should be equivalent substitute mode, is included within the scope of protection of the utility model.
