Description
Technical Field
The utility model relates to an audio amplifier field especially relates to a novel audio amplifier of making an uproar falls.
Background
The sound box refers to a device capable of converting an audio signal into sound, and in popular speaking, the sound box refers to a sound box main unit box body which is provided with a power amplifier or an external power amplifier, and the sound box generates sound after the audio signal is amplified, so that the sound of the sound box becomes louder. Loudspeaker devices are used in many situations, such as lectures, concerts, large shows, exhibitions, and the like. When a horn in the loudspeaker box makes a sound, air flow is generated, and the air flow impacts on the inner wall of the cabinet to make noise, so that the air flow needs to be led out. The air outlet in the existing sound box is usually linear, which can generate noise and influence the sound effect of the sound box playback.
Accordingly, the prior art is deficient and needs improvement.

Furthermore, the left side wall and the right side wall of the box body are cambered surfaces which are inwards concave.
Further, the box top surface is equipped with the frame roof beam, the frame roof beam is located between the lateral wall around the air guide plate and the box of the left and right sides, the apron is located frame roof beam top surface, the top surface of air guide plate with the apron parallel and level.
Furthermore, the top surface of the partition board is provided with an air guide box, the air guide box is provided with a plurality of air guide holes, and the cover plate is provided with air holes corresponding to the air guide box.
Furthermore, a plurality of threaded holes are formed in the frame beam, counter bores are formed in the positions, corresponding to the threaded holes, of the cover plate, and screws penetrate through the counter bores and are locked in the threaded holes so as to fix the cover plate on the frame beam.
By adopting the scheme, the utility model discloses following beneficial effect has:
(1) the utility model arranges the flow guide cavities at the two sides of the horn, the air flow generated by the horn can be discharged from the air guide box above and can be discharged from the flow guide cavities at the two sides, thus realizing more efficient energy conversion;
(2) the utility model discloses establish the left and right sides wall of box into the cambered surface to the indent, the design of cambered surface can reduce the windage to the noise reduction.
Drawings

Fig. 2 is a top view of the present invention.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and fig. 2, the present invention provides a novel noise reduction speaker, including: the box 1, locate the apron 2 of 1 top surfaces of box, locate baffle 3 in the middle of the box 1, locate the mounting panel 4 of the 3 left and right sides face of baffle and locate loudspeaker 5 on the mounting panel 4. The inside wall of the left and right sides of box 1 is equipped with support 6, be equipped with air guide plate 7 on support 6, support 6 is used for fixed air guide plate 7. The air guide plate 7 is parallel to the partition plate 3, the bottom surface of the air guide plate 7 does not extend to the bottom surface of the box body 1, an air guide cavity 100 is formed between the air guide plate 7 on the left side and the left side wall of the box body 1, the air guide plate 7 on the right side and the right side wall of the box body, the air guide cavity 100 is communicated with the outside, and partial air flow generated by the horn 5 enters the air guide cavity 100 from the lower part of the horn 5 and is then discharged to the outside. The width of the support frame 6 is the width of the gas guide chamber 100.
The left side wall and the right side wall of the box body 1 are inwards concave cambered surfaces 200, and the design of the concave cambered surfaces 200 can reduce wind resistance, so that noise is reduced.
The top surface of the box body 1 is provided with a frame beam 8, the frame beam 8 is positioned between the front and rear side walls of the air guide plate 7 on the left side and the rear side wall of the box body 1, the cover plate 2 is arranged on the top surface of the frame beam 8, and the top surface of the air guide plate 7 is flush with the cover plate 2. Specifically, a plurality of threaded holes are formed in the frame beam 8, counter bores are formed in the positions, corresponding to the threaded holes, of the cover plate 2, and screws penetrate through the counter bores and are locked in the threaded holes to fix the cover plate 2 on the frame beam 8.
