Abstract
Integral type bugle, including wave guide portion and loudspeaker portion, wave guide portion includes on integrated into one piece's the wave guide casing under casing and the wave guide, the casing includes the flange on the wave guide, go up acoustic streaming cavity and last loudspeaker connecting portion, the casing includes the lower flange under the wave guide, lower acoustic streaming cavity and lower loudspeaker connecting portion, on the wave guide under casing and the wave guide casing fixed to closing, it forms flange portion with lower flange joint to go up the flange, go up the acoustic streaming cavity and connect formation acoustic streaming cavity with lower acoustic streaming cavity, go up the loudspeaker connecting portion and connect formation loudspeaker connecting portion with lower loudspeaker connecting portion. Because on the wave guide under casing and the wave guide casing be integrated into one piece's structure, the casing is to closing when fixing under casing and the wave guide on the wave guide, acoustic streaming cavity and loudspeaker connecting portion are an overall structure, it is better, more pleasing to the eye that the bugle structure of two parts formula before in is compared to the wholeness of wave guide portion, the connection structure performance is good, has reduced the influence of sound leakage, has also saved complicated technologies such as manual viscose, polishing, simple to operate.
Description
Technical field
This utility model is related to a kind of integral type bugle.
Background technology
Bugle is that a kind of sound amplifies product, is commonly used in the public address equipments such as audio amplifier, loudspeaker.It includes source of sound rear end
With the front end that amplifies, the front end that amplifies is the horn mouth of a taper.Operationally, bugle by sound wave by the horn mouth of taper by sound
Sound is concentrated, and can make the distant of sound biography.The structure design of bugle is to whole public address equipment to the sound timbre of external diffusion
Quality, whether distortion has a very important role.Existing bugle structure imperfection, existing bugle is typically by two parts group
Become, the straight end portion of bugle is generally glass steel material, and the crooked end of bugle is wooden material, in straight end portion with crooked end even
When connecing, then the general craft viscose glue that passes through is being screwed, and Joining Technology is complicated, is simultaneously connected with the low outward appearance of precision also not
Attractive in appearance, screw connection is insecure, easily causes sound leakage, and wood materials easily split simultaneously, will also result in sound leakage.
Content of the invention
The technical problems to be solved in the utility model is to provide that a kind of structure is simple, easy for installation, attachment structure performance is good
Integral type bugle.
In order to solve above-mentioned technical problem, this utility model includes waveguide pipe portion and flare, and described waveguide pipe portion includes
Integrally formed waveguide upper shell and waveguide lower house, waveguide upper shell includes upper flange, upper acoustic streaming cavity and upper loudspeaker
Connecting portion, waveguide lower house includes lower flange, lower acoustic streaming cavity and lower loudspeaker connecting portion, waveguide upper shell and waveguide
Lower house pairing is fixed, and upper flange is connected formation flange portion with lower flange, and upper acoustic streaming cavity and lower acoustic streaming cavity connect formation sound
Stream cavity, upper loudspeaker connecting portion and lower loudspeaker connecting portion connect formation loudspeaker connecting portion.Because waveguide upper shell and waveguide
The structure that lower house is formed in one, when waveguide upper shell and waveguide lower house pairing are fixing, acoustic streaming cavity and loudspeaker
Connecting portion is an overall structure, and the globality of waveguide pipe portion is more preferable compared to the bugle structure of former two-part, more beautiful
See, attachment structure performance is good, decreases the impact of sound leakage, also eliminates the complicated technologies such as manual viscose glue, polishing, easy for installation.
As further improvement of the utility model, described waveguide upper shell and waveguide lower house are bolted
Mode pairing fix.
As further improvement of the utility model, described waveguide upper shell is glass steel material, under described waveguide
Housing is glass steel material.
As further improvement of the utility model, waveguide upper shell is provided with sealed groove, in waveguide lower casing
Body is provided with the seal convexity matching with sealed groove.By the cooperation of seal convexity and sealed groove, further increase
The sealing that waveguide upper shell is connected with waveguide lower house, reduces the impact of sound leakage.
As further improvement of the utility model, upper loudspeaker connecting portion is provided with fixed lobe, connects in lower loudspeaker
Portion is provided with fixed lobe.
As further improvement of the utility model, the mode that described flare is bolted is with loudspeaker connecting portion even
Connect.
In sum, the utility model has the advantages that structure is simple, easy for installation, attachment structure performance is good.
Brief description
Come that the utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of waveguide upper shell of the present utility model.
Fig. 3 is the structural representation of waveguide lower house of the present utility model.
Specific embodiment
As shown in Figure 1 to Figure 3, this utility model includes waveguide pipe portion and flare 1, and described waveguide pipe portion includes integrally becoming
The waveguide upper shell 2 of type and waveguide lower house 3, described waveguide upper shell 2 is glass steel material, described waveguide lower casing
Body 3 is glass steel material, and waveguide upper shell 2 includes upper flange 4, upper acoustic streaming cavity 5 and upper loudspeaker connecting portion 6, under waveguide
Housing 3 includes lower flange 7, lower acoustic streaming cavity 8 and lower loudspeaker connecting portion 9, is provided with sealed groove 10 on waveguide upper shell 2,
The seal convexity 11 being matched with sealed groove 10, waveguide upper shell 2 and waveguide lower casing are provided with waveguide lower house 3
The mode pairing that body 3 is bolted is fixed, and upper flange 4 is connected formation flange portion 12, upper acoustic streaming cavity 5 He with lower flange 7
Lower acoustic streaming cavity 8 connects formation acoustic streaming cavity 13, and upper loudspeaker connecting portion 6 and lower loudspeaker connecting portion 9 connect formation loudspeaker connecting portion
14, upper loudspeaker connecting portion 6 is provided with fixed lobe 15, fixed lobe 15, described flare are provided with lower loudspeaker connecting portion 9
1 mode being bolted is connected with loudspeaker connecting portion 14.Because waveguide upper shell 2 and waveguide lower house 3 are integrated
The glass steel material structure of molding, when waveguide upper shell 2 and waveguide lower house 3 pairing are fixing, acoustic streaming cavity 13 and loudspeaker
Connecting portion 14 is an overall structure, and the globality of waveguide pipe portion is more preferable compared to the bugle structure of former two-part, more
Plus attractive in appearance, attachment structure performance is good, decreases the impact of sound leakage, also eliminates the complicated technologies such as manual viscose glue, polishing, installation side
Just.By the cooperation of seal convexity 11 and sealed groove 10, further increase waveguide upper shell 2 and waveguide lower house 3
The sealing connecting, reduces the impact of sound leakage.The upper and lower loudspeaker connecting portion 9 of upper loudspeaker connecting portion 6 is provided with fixed lobe 15,
Flare 1 so can be conveniently made to be connected with loudspeaker connecting portion 14.
