Description

Technical field: [0001] The invention relates to the technical field of electronic digital products, in particular to a portable amp shell that can flexibly adjust the degree of tightness. 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, because ...
