The turning point of the cavity that amplifies corresponding with the stitching position of the first type body and second type body.
Preferably, the air inlet section is circle, and mouthful section that amplifies is rectangle.
Preferably, the air inlet and the mouth that amplifies are integrally formed with body contacts part and are provided with reinforcing rib.
A kind of corner circular arc linear array bugle described in the utility model, the advantage is that, make vibrating diaphragm spoke by the cavity that amplifies
The wave surface for the sound penetrated becomes larger, and is made eventually by biggish amplify mouth and Space Coupling due to the turnover for the cavity that amplifies
Acoustic radiating impedance increases and is pure resistance, therefore the present apparatus is high-efficient, distortion is small, transient response is good.Moreover, in the cavity that amplifies
Turning point is similar parabolical shape, is more suitable middle pitch and Horn, improves sound transmission efficiency.
The present apparatus is made of three dismountable type bodies, facilitates processing and fabricating, while allowing the first type body and second type body
Split form the cavity that amplifies of similar crescent shape, make sound in the cavity that amplifies by bigger radiation impedance, can be more
Secondary reflection forms distinctive tone color, Larger Dynamic, sound inertia, air sense, in terms of outclass common speaker.

Specific embodiment
As shown in Figures 1 to 4, a kind of corner circular arc linear array bugle of the utility model, including ontology 1, ontology 1 include successively
The air inlet 11 of connection, amplify cavity 13 and the mouth 12 that amplifies, and the mouth 12 that amplifies is in open state, and the cavity 13 that amplifies extends along direction
Longitudinal cross-section is in " 7 " font, and 13 turning point of cavity that amplifies is arc-shaped.The utility model makes vibrating diaphragm spoke by the cavity 13 that amplifies
The wave surface for the sound penetrated becomes larger, eventually by biggish amplify mouth 12 and Space Coupling, due to turning for the cavity 13 that amplifies
Folding makes acoustic radiating impedance increase and be pure resistance, therefore the present apparatus is high-efficient, distortion is small, transient response is good.Moreover, amplifying
The turning point of cavity is similar parabolical shape, is more suitable middle pitch and Horn, improves sound transmission efficiency.
In the present embodiment, amplify the crescent that the cross section of cavity 13 surrounds by two camber lines, and amplify cavity 13
Turnover direction is extended to the center of circle direction of two camber lines.The cavity 13 that amplifies is formed by shape and is more suitable for spoke with Hi-Mid
It penetrates, since turning point is by bigger radiation impedance, and also the interior length for extending the cavity 13 that amplifies in a limited space, sound
Distinctive tone color can be formed by multiple reflections, Larger Dynamic, sound inertia, air sense, in terms of outclass other sounds
Case number (CN) angle.The cross-sectional area of cavity 13 of amplifying is gradually expanded from air inlet 11 to the mouth 12 that amplifies, and the mouth 12 that amplifies is far from air inlet
The development length of 11 sides is greater than the development length of the other side.Because the overbending direction for the cavity 13 that amplifies, makes sound in the present apparatus
The cavity 13 that amplifies guidance under, can to far from air inlet 11 side extend, and the setting for the mouth 12 that amplifies can then allow sound into
One step obtains multiple reflection, while balancing the reflection probability of two sides, avoids the sound of radiation to amplify mouth 12 and bugle
Interference is generated at aditus laryngis and influences sound quality.
In the present embodiment, ontology 1 includes the first type body 14, second type body 15 and the third type body 16 being detachably connected,
First type body 14 and second type body 15 are spliced to form air inlet 11, the corresponding cavity 13 that amplifies on the first type body 14 and second type body 15
Position be equipped with curved surface, two curved surface bending directions are consistent, and third type body 16 includes amplifying mouth 12, and third type body 16 and the
The turning point of the corresponding cavity 13 that amplifies of the stitching position of one type body 14 and second type body 15.Such setting makes to make processing
The cavity 13 that amplifies for being spliced to form rounding off between convenient and various body.Amplify cavity 13 leading portion by two curved surfaces
Composition has the function of the reflection preferably compressing and concentrating sound and sound is enable to pass through multiple non-scheduled service, reinforces
Bugle to the efficiency of acoustic radiating, meanwhile, shape of the section similar to hyp shape cooperation turning point section parabolically, energy
Further adapt to the transmission frequency and radiation efficiency of Hi-Mid.11 section of air inlet is circle, and 12 section of mouth that amplifies is rectangle.Sound
After sound enters the device by circular air inlet 11, reflects in the cavity that amplifies, is gradually radiated by the mouth 12 that amplifies of rectangle,
By circular flat sound wave be converted into being not susceptible to interference effect etc. phases rectangle plane sound wave, improve the quality of acoustic.Air inlet
Mouth 11 and the mouth 12 that amplifies are provided with reinforcing rib 17 with the integrated molding of 1 contact portion of ontology.Since the present apparatus needs various arcs
The cooperation in face and curved surface could form the shape of the special cavity 13 that amplifies, to guarantee to improve tone color and sound quality, therefore, shape
It is simple in order to make, need to be arranged multiple cambered surfaces, and the effect of reinforcing rib 17 is exactly the intensity improved at cambered surface, avoids abrasion etc.
The vibration of ontology 1 is caused, to affect the sound quality of bugle, effectively avoids the generation of noise.
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.
