Including outer frame body and main part, the main part sets up the sound chamber and assembles loudspeaker in the sound chamber, the back and four sides of main part all are provided with a plurality of and are the top arch that the triangle-shaped position was arranged, the main part counterpoint is laid in the outer frame body, the terminal top of top arch touches in the inner wall of outer frame body, form the clearance between main part and the outer frame body. The utility model discloses with establish the sound chamber in the main part and install loudspeaker in the sound chamber, satisfy the structure of conventional audio amplifier, and establish an outer frame body at the main part overcoat to and through the protruding area of contact as supporting of a plurality of top between main part and the outer frame body, form the clearance and reduce main part and outer frame body between outer frame body and main part, reach the effect of damping, its simple structure, the equipment is convenient, has very strong practicality.
Description
Technical Field
The utility model belongs to the technical field of the audio amplifier technique and specifically relates to a damping audio amplifier suitable for black glue record player.
Background
As is well known, a black matrix disc player, also called a gramophone, is an original playback device in which the sound is stored in an arc-shaped groove that is acoustically engraved in the black matrix plane of a turntable. The record is placed on a turntable and rotated under a stylus. Since vinyl records can be easily reproduced in large quantities and the playback time is longer than that of most of the cylindrical recording media, the vinyl record player is also known as one of the most popular inventions of edison.
At present, current vinyl record machine does not rely on a loudspeaker to carry out sound and sends out outward, but adopts the audio amplifier to play, utilizes the volume advantage of audio amplifier, and the effectual whole volume that has reduced, however, the audio amplifier is when the sound of sending out, and self can produce the vibration, and the existence of this kind of vibration often can influence the friction emergence between stylus and the vinyl record, and then brings the destruction on tone quality, and the product experience to the user brings not good influence.
Disclosure of Invention
To the not enough of existence among the above-mentioned prior art, the utility model aims to provide a damping audio amplifier suitable for black glue record player.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a damping audio amplifier suitable for black gel record player, includes outer frame body and main part, the main part sets up the sound chamber and assembles loudspeaker in the sound chamber, the back and four sides of main part all are provided with a plurality of and are the top arch that the triangle-shaped position was arranged, the main part is laid in the frame to the counterpoint, the terminal top of top arch touches in the inner wall of outer frame body, form the clearance between main part and the outer frame body.
Preferably, the apex is in the shape of a triangular prism.
Since the technical scheme is used, the utility model discloses with establish the sound chamber in the main part and install loudspeaker in the sound chamber, satisfy the structure of conventional audio amplifier, and establish an outer frame body at the main part overcoat to and through the protruding contact area who regards as the support of a plurality of top between main part and the outer frame body, form the clearance and reduce main part and outer frame body between outer frame body and the main part, reach the effect of damping, its simple structure, the equipment is convenient, has very strong practicality.
Drawings
Fig. 1 is a schematic diagram of the structural principle of the embodiment of the present invention.
Fig. 2 is a schematic combined structure diagram according to an embodiment of the present invention.
Fig. 3 is a schematic structural diagram of the outer surface of the main body according to the embodiment of the present invention.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
As shown in fig. 1 to 3, the vibration-damping sound box suitable for a black matrix compact disc player provided by this embodiment includes an outer frame 1 and a main body 2, the main body 2 is provided with a sound cavity 3 and a speaker 4 is assembled in the sound cavity 3, the back and four sides of the main body 2 are respectively provided with a plurality of top protrusions 5 arranged in a triangular direction, the main body 2 is placed in the outer frame 1 in a para-position, the tail ends of the top protrusions 5 are in contact with the inner wall of the outer frame 1, and a gap is formed between the main body 2 and the outer frame 1.
Further, the top protrusions 5 are triangular prism-shaped.
During the operation of the concrete application, the outer frame body 1 is used for being fixed in the black tape record player, and with the sound chamber 3 in the main part 2 and install loudspeaker 4 in the sound chamber 3, satisfy the structure of conventional audio amplifier, and establish an outer frame body 1 in the main part 2 overcoat, and through a plurality of top protruding 5 as the support between main part 2 and the outer frame body 1, form the clearance and reduce the area of contact of main part 2 and outer frame body 1 between outer frame body 1 and main part 2, thereby attenuate in the transmission process of vibration, hinder the transmission of vibration, and then reach the effect of damping.
The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
