Description
Technical Field
The utility model relates to a broadcasting equipment technical field, in particular to high-fidelity stereo set that broadcasting was used.
Background
In broadcasting, the sound quality of a sound box directly influences the receiving effect and the sensory effect of listeners, and because broadcasting is directed to vast listeners, a larger sound box is generally adopted, the larger the sound box is, the more complex the structure is, and the amplitude of sound is large, so that resonance of other parts is easily caused, and thus noise is generated to influence the sound quality and cause distortion.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a can reduce the high-fidelity stereo set that produces the noise because of resonance.
The technical scheme of the utility model is that:
the high-fidelity sound box for broadcasting is characterized in that the side wall of the sound box is provided with at least one sound amplification round hole, an annular cavity is arranged behind the sound amplification round hole, the bottom of the annular cavity is sealed, a sound production loudspeaker is suspended in the annular cavity through a damping column, and the front end of the sound production loudspeaker and the rear wall of the round hole are sealed through a flexible pad; the panel of stereo set all compounds to bond has the damping coating, and all fills up the flexblepad between the panel of continuous connection, the damping post is formed by spaced elastic layer and rigid layer complex.
Furthermore, the damping column is formed by compounding soft rubber and hard rubber at intervals.
Further, the damping coating is water-based damping paint.
Furthermore, the flexible pad adopts butyl rubber damping pad.
Furthermore, a circle of damping columns are arranged on the peripheral wall of the sounding horn, and two circles of damping columns are annularly arranged on the bottom side of the sounding horn.
The utility model discloses an useful part lies in:
the utility model discloses main sound production position (sound production loudspeaker) at the audio amplifier has carried out institutional advancement, and it is in unsettled state, and the damping post can greatly subdue sound production loudspeaker's self vibration transmission to the audio amplifier body, reduces resonance, and secondly the panel of stereo set all compounds bonding has the damping coating, and all fills up between the panel of continuous connection has the flexible pad, increases the damping of vibration, reduces its vibration range to avoid the production of noise, promote the high fidelity of audio amplifier.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the suspension of the bottom of the acoustic horn;
fig. 3 is a schematic view of the damping column structure.
In the figure: the sound production device comprises a sound production loudspeaker 1, an annular cavity 2, a damping column 3, an elastic layer 31, a rigid layer 32, a sound amplification round hole 4, a flexible cushion 5, a damping coating 6 and a plate 7.
Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1-3:
the high-fidelity sound box for broadcasting is characterized in that the side wall of the sound box is provided with at least one sound amplification round hole 4, an annular cavity 2 is arranged behind the sound amplification round hole 4, the bottom of the annular cavity 2 is sealed, a sound production loudspeaker 1 is suspended in the annular cavity through a damping column 3, and the front end of the sound production loudspeaker 1 and the rear wall of the round hole are sealed through a flexible pad 5; the panel 7 of stereo set all compounds and bonds and has damping coating 6, and all fills up flexible pad 5 between the panel 7 of continuous connection, damping post 3 is formed by the complex of spaced elastic layer 31 and rigid layer 32.
Specifically, the damping column 3 is formed by compounding soft rubber and hard rubber at intervals, and the structure has the advantages of slowing down the transmission of vibration, ensuring enough supporting strength and reducing the vibration amplitude.
The damping coating 6 is a water-based damping coating which is prepared by adding a proper amount of filler and auxiliary materials into high molecular resin, is safe and environment-friendly because water is used as a dispersion medium, can be coated on the surfaces of various metal plate-shaped structures and has vibration reduction, heat insulation and certain sealing performance, and is convenient to construct because the coating can be directly sprayed on the surfaces of the structures.
Specifically, the flexible pad 5 is a butyl rubber damping pad.
Specifically, a circle of damping columns 3 is arranged on the peripheral wall of the sounding horn 1, and two circles of damping columns 3 are annularly arranged on the bottom side of the sounding horn.
The utility model discloses main sound production position (sound production loudspeaker 1) at the audio amplifier has carried out institutional advancement, it is in unsettled state, damping post 3 can greatly subdue self vibration transmission to the audio amplifier body of sound production loudspeaker 1, reduce resonance, secondly the equal complex bonding of panel 7 of stereo set has damping coating 6, and all fill up flexible pad 5 between the panel 7 of continuous connection, increase the damping of vibration, reduce its vibration range, thereby avoid the production of noise, promote the high fidelity of audio amplifier.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
