Abstract
The utility model discloses a kind of five equal part linear arrays to divide bugle, including ontology, described ontology one end is equipped with air inlet, the other end of the ontology is equipped with the mouth that amplifies in open state, the air inlet and the mouth that amplifies is interconnected, it is equipped with hemispherical concave cavity between the air inlet and the mouth that amplifies, is additionally provided with the baffle that the space that amplifies inside one or two is divided into five equal parts along airflow direction on the concave cavity.The advantage is that: the cavity that amplifies is divided into five equal parts by setting baffle, to allow sound by being got more careful, the especially propagation of high pitch when the bugle, it can be discharged by compression, oscillation space is reduced, avoids high pitch from being distorted or generates noise, so as to reach farther radiation length.
Description
Technical field
The utility model relates to a kind of speaker bugles, and in particular to a kind of five equal part linear arrays segmentation bugle.
Background technique
Bugle loudspeaker is made of vibrational system (high pitch head) and bugle two parts.Vibrational system and cone loudspeaker phase
Seemingly, its vibrating diaphragm not instead of cone, a top dome shape diaphragm unlike.Vibration of membrane of shaking passes through bugle (passing through two secondary reflections)
The radiative acoustic wave into air.Its frequency is high, gives great volume, and is usually used in outdoor and square field public address.The bugle loudspeaker of the prior art
Most of to be arranged in single pass funnel-form, mechanical strength is lower, when the voice unit of speaker issues the sound of high frequency, high pitch
Directly expanded by loudspeaker bugle, but such bugle can generate biggish vibration, largely effect on the quality of high pitch, is occurred high
The failures such as sound distortion or noise, and the loudspeaker of this type cannot be compressed due to there is biggish space that high pitch is allowed to spread
It concentrates, after sound output, diffusion dies down quickly, and transmitting range is very close, and target is indefinite, is easy to be dropped significantly by external interference
The low pronunciation special efficacy of loudspeaker.
Utility model content
In order to solve the above-mentioned problems of the prior art, the utility model aim is to provide a kind of five equal part linear arrays point
Cut bugle.It is more careful that the utility model can get sound, and high pitch is compressed from the cavity that amplifies, and has better sound quality
With farther away propagation distance.
A kind of five equal parts linear array described in the utility model divides bugle, including ontology, described ontology one end be equipped with into
Port, the other end of the ontology are equipped with the mouth that amplifies in open state, and the air inlet and the mouth that amplifies are interconnected, described
Air inlet and the mouth that amplifies between be equipped with hemispherical concave cavity, be additionally provided with inside one or two the sky that amplifies on the concave cavity
Between the baffles of five equal parts is divided into along airflow direction.
Preferably, there are two the air inlets and arranged side by side, one of air inlet tilts down, another air inlet
Mouth inclination upwards, the concave cavity and air inlet correspond.
Preferably, the ontology includes the first type body and second type body being detachably connected, the first type body and
Second type body is identical integral structure.
Preferably, the air inlet section is circle, and mouthful section that amplifies is rectangle.
Preferably, the air inlet and with body contacts part be integrally formed be provided with reinforcing rib.
A kind of five equal parts linear array described in the utility model divides bugle, the advantage is that, setting baffle is the cavity that amplifies
Five equal parts are divided into, to make sound more careful by being got when the bugle, the especially propagation of high pitch can be released by compression
It puts, reduces oscillation space, avoid high pitch from being distorted or generate noise, so as to reach farther radiation length.
Loudspeaker bugle generally can connect driver in air inlet, by the special setting of the air inlet of the utility model,
Sound is allowed to be divided further into two opposite radiation directions, so that sound be allowed to be further compressed and concentrated radiation.And this
Device is spliced to form mutually by two identical structures, and the positions such as intermediate cavity that amplifies facilitate the maintenance and replacement of baffle.

Specific embodiment
As shown in Figures 1 to 4, a kind of five equal part linear arrays of the utility model divide bugle, including ontology 1,1 one end of ontology are set
There is air inlet 11, the other end of ontology 1 is equipped with the mouth 12 that amplifies in open state, and air inlet 11 and the mouth 12 that amplifies are interconnected, into
It is equipped with hemispherical concave cavity 13 between port 11 and the mouth 12 that amplifies, 4 is additionally provided on concave cavity 13, inside is amplified sky
Between the baffles 14 of five equal parts is divided into along airflow direction.The utility model setting 14 cavitys that amplify of baffle are divided into five equal parts,
To allow sound by being got more careful, the especially propagation of high pitch when the bugle, it can be discharged by compression, it is empty to reduce vibration
Between, it avoids high pitch from being distorted or generates noise, so as to reach farther radiation length.Being divided into five equal parts can allow high pitch to be compressed again
Respectively to external radiation after internal reflection, if continue subdivision be likely to result in baffle 14 the thickness effect space that amplifies it is big
It is small, and the bugle that amplifies is had an impact.
In the present embodiment, there are two air inlets 11 and arranged side by side, one of air inlet 11 tilts down, another
Air inlet 11 tilts upwards, and concave cavity 13 and air inlet 11 correspond.Loudspeaker bugle generally can connect drive in air inlet
Dynamic device allows sound to be divided further into two opposite radiation directions by the special setting of the air inlet 11 of the utility model,
To allow sound to be further compressed and concentrated radiation.Ontology 1 includes the first type body 15 and second type body 16 being detachably connected,
First type body 15 and second type body 16 are identical integral structure.The present apparatus splices mutually shape by two identical structures
At the positions such as intermediate cavity that amplifies facilitate the maintenance and replacement of baffle 14.11 section of air inlet is circle, and amplify 12 section of mouth
For rectangle.After sound enters the device by circular air inlet 11, reflected in the cavity that amplifies, gradually by the mouth 12 that amplifies of rectangle
Radiate, by circular flat sound wave be converted into being not susceptible to interference effect etc. phases rectangle plane sound wave, improve acoustic
Quality, the especially present apparatus can be further avoided interfering in this way, more clearly listened by be allowed audience by two 11 collective effects of air inlet
To the sound of horn.Air inlet 11 and the integrated molding of 1 contact portion of ontology is provided with reinforcing rib 17, keeps ontology 1
Fastness prevents the vibration of sound from deviate ontology 1, facilitates the connection of the present apparatus and driver.
For those skilled in the art, it can make other each according to the above description of the technical scheme and ideas
The corresponding change of kind and deformation, and all these changes and deformation all should belong to the guarantor of the utility model claims
Within the scope of shield.
