Abstract

The invention discloses a portable headphone amplifier casing for improving bandage stability. The portable headphone amplifier casing includes a casing body, first fixing grooves which are mutually symmetrically distributed are formed in the upper and lower ends of one side of the bottom of the casing, clamping plates are disposed in the first fixing grooves, the inner side of each first fixing groove is provided with a second fixing groove communicated with the first fixing groove, a first rotating wheel and a second rotating wheel which are symmetrically distributed are disposed in each second fixing groove, the first rotating wheel is connected with the second rotating wheel through a fixing belt, one side of the fixing belt is connected with the inner side of the clamping plate, the second rotating wheels are connected with a rotating shaft in the form of gear meshing, the upper end of the bottom of the casing is provided with a first adjusting groove, and an adjusting gear is arranged in the first adjusting groove. The other side of the bottom of the casing is provided with a first clamping groove clamped with the clamping plate, and the joint of the fixing belt and the clamping plate is provided with an elastic belt. The inner side of the fixing belt is provided with anti-sliding rubber, the anti-sliding rubber is distributed in a segmented mode, and the length of the anti-sliding rubber is equal to the width of the casing. The design is simple to operate, and the portable headphone amplifier casing is high in comprehensive practicality and easy to popularize and use.

Description

[0001] Technical field: [0002] The invention relates to the technical field of electronic digital products, in particular to a portable amp shell that improves the stability of a fixing band. [0003] Background technique: [0004] Headphone Amplifier is the headphone power amplifier. Because the relatively large headphones have high impedance, the small Walkman cannot be carried or pushed, so the headphone amplifier is needed. The active one is connected between the sound source and the headphones. [0005] The impedance of ordinary earphones is generally 16-32 ohms. In order to obtain a better low-frequency response, mid-to-high-end HIFI fever earphones often use high-density coils and long-stroke designs. At this time, the impedance of the earphones will be as high as 200-600 ohms. Or the power amplifiers are all low-impedance output designs. When encountering such high-impedance headphones, the output power will be doubled and the frequency response curve will be destroye...
