Embodiment 1
[0056] Embodiment 1: as Figure 1-12 As shown, the present invention provides a technical solution, a power amplifier sound with long service life, including a sound base 1, a groove 2 is opened in the middle of the bottom end of the sound base 1, and a rectangular plate 3 is bonded to the middle of the inside of the groove 2. The middle part of the bottom end of the plate 3 is bonded with a protective plate 4, and the middle part of the bottom end of the protective plate 4 is provided with a limiting groove 5, and the middle part of the inner wall of the limiting groove 5 is bonded with a rubber pad 6, and the bottom edge of the audio base 1 is located inside the protective plate 4. The rubber pad 6 is located inside the limiting groove 5. The shape of the rubber pad 6 is the same as that of the limiting groove 5, which facilitates the installation of the rubber pad 6 and reduces the installation difficulty of the rubber pad 6. The top of the protective plate 4 corresponds to ...

Abstract
The invention discloses a power amplifier sound box with a long service life. The box comprises a sound box base body, and a groove is formed in the middle of the bottom end of the sound box base body; a rectangular plate is adhered to the middle part of the interior of the groove; a protective plate is adhered to the middle part of the bottom end of the rectangular plate; a limiting groove is formed in the middle of the bottom end of the protective plate; a rubber pad is adhered to the middle part of the inner wall of the limiting groove; and the top end of the protective plate is provided with a rectangular groove corresponding to the edge of the bottom end of the sound box base body. The structure is scientific and reasonable, safe and convenient use, the sound box comprises the sound box base body, the groove, the rectangular plate, the protective plate, the limiting groove, the rubber pad and the rectangular groove. According to the invention, the friction force between the soundbox base body and the plane can be increased, the sound box base body is prevented from sliding on the plane, the bottom of the sound box base body is protected, and the direct collision between the bottom of the sound box and an object is prevented, so that the sound box base body is protected, and the service life of the sound box base body is prolonged.
Description
technical field [0001] The invention relates to the field of audio technology, in particular to a power amplifier audio with long service life. Background technique [0002] But the sound system generally includes: sound source equipment: (list: DVD, CD, MP3, MP4, computer, mobile phone, microphone and other sound source output devices), audio signal dynamic processing equipment (compressor, effector, mixer, etc.) , audio processor, equalizer and other audio signal processing equipment), audio signal amplification equipment (pre-stage power amplifier, post-stage power amplifier, digital power amplifier and other analog power amplifiers, equipment), sound restoration equipment (full-range speakers, ceiling speaker, sound column, line array speaker, array speaker, tweeter, subwoofer, etc.), the development history of technology can be divided into four stages: tube, transistor, integrated circuit, field effect tube; [0003] However, when the existing speakers are in use, the...
