an acousto-optic amplifier

Abstract

The invention discloses an acousto-optic amplifier. The device comprises a body and a round rotating column, a winding device is fixedly mounted on the lower side of the right end of the machine body;the winding device comprises a cylindrical part, a winding groove, silica gel rings, a sliding block, a conical sliding block and a first spring, the silica gel rings are symmetrically bonded to theleft side and the right side of the interior of the winding groove, and a wool fiber layer, a silicon nitride ceramic layer, an aluminum foil layer, a magnesium layer, a polypropylene layer and a solid wood layer are arranged in the machine body. The machine body is enclasped and turned over in a front-and-back way, the angle of the body is changed, the inserting rod is inserted into the positioning groove; the machine body angle can be conveniently and temporarily changed; the plug cord is separated from the sliding block and enters the coiling groove, and the plug cord is further limited tobe separated from the coiling groove outwards through the closed sliding block, so that the machine body looks more regular, the polypropylene layer and the solid wood layer are low in distortion rate and good for expressing various types of sounds, and when the volume of the machine body is large, the sound emitted by the machine body is more fidelity.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to an acousto-optic amplifier. Background technique [0002] Acousto-optic amplifier, also known as loudspeaker, is a conversion device that converts electrical energy into sound. When different electronic energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes paper The disk vibrates, because the electronic energy changes at any time, the coil of the speaker will move forward or backward, so the paper disk of the speaker will move accordingly, and this action changes the density of the air to produce sound. [0003] The existing acousto-optic amplifier is installed on the wall with a fixed-angle mounting bracket, and then the body is hung on the mounting bracket so that the body maintains a certain inclination angle. Perfect, the installation brackets are often designed with different ang...

Problems solved by technology

[0003] The existing acousto-optic amplifier is installed on the wall with a fixed-angle mounting bracket, and then the body is hung on the mounting bracket so that the body maintains a certain inclination angle. Perfect, often design mounting brackets with different angles, so that a single mounting bracket cannot be used in different spaces. At the same time, the shell of the body is mostly made of alloy pressed layer, but when the actual volume of the body is loud, the shell of the body will also vibrate. This kind of vibration will be a little different from the actual sound, which will cause the actual sound from the body to be distorted. At the same time, in order to meet the needs of connecting power sockets with different distances, the plug wire will be designed very long. When the power socket is very close to the body, the plug is connected to the power supply. When plugged into the socket, the plug wire is in a hanging state, which looks very irregular
