Abstract

The invention discloses a portable headphone amplifier housing for improving the recovery efficiency of fixing bands. The portable headphone amplifier housing comprises a shell, symmetrically distributed first fixing grooves are formed in upper and lower ends of one side of the bottom of the shell, clamping plates are arranged in the first fixing grooves, second fixing grooves communicating with the first fixing grooves are formed in the inner sides of the first fixing grooves, first rotating wheels and second rotating wheels, which are symmetrically distributed, are arranged in the second fixing grooves, the first rotating wheels and the second rotating wheels are connected through the fixing band, one side of each fixing band is connected with the inner sides of the clamping plates, thesecond rotating wheels are connected with rotating shafts in a gear engagement manner, a first adjustment groove is formed in the upper end of the bottom of the shell, an adjustment gear is arrangedin the first adjustment groove, first necks clamped with the clamping plates are formed in the other side of the bottom of the shell, the second rotating wheels are connected with one ends of the fixing bands through ruler springs, and the design is simple in operation, high in comprehensive practicality, and is easy to popularize and use.

Description

Technical field: [0001] The invention relates to the technical field of electronic digital products, in particular to a portable amp shell that improves the recovery efficiency of a fixed belt. Background technique: [0002] 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. [0003] 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 destroyed, bec...
