| titleOfInvention | Low-noise monolithic integrated amplifier |
| abstract | The utility model discloses a monolithic integrated amplifier of low noise, including the amplifier main part, the amplifier main part is arranged in the box, the box includes bottom plate, curb plate and movable roof, the equal fixedly connected with rubber layer in top of curb plate, the outside of bottom plate, curb plate and movable roof is provided with the shell, the internal connection of shell has the acoustic celotex board, the inside of acoustic celotex board is provided with the sound-absorbing layer, and forms the amortization chamber between sound-absorbing layer and the acoustic celotex board, the through-hole has evenly been seted up on the sound-absorbing layer. The utility model discloses a set up the sound absorbing layer at the box inner wall, carry out the preliminary absorption to the noise, set up the amortization chamber in the sound absorbing layer, the amortization intracavity sets up the damping plate of interval symmetry, sets up protruding piece between the adjacent damping plate in the outside, extension noise sound wave route, the noise reduction, the amortization chamber outside sets up the acoustic celotex board, further carries out the separation to the noise, and noise reduction is effectual. |
