Abstract

An earphone and audio amplifier integrated with a DAC and a sound effect processing circuit, comprising an interface part and a control part. The interface part comprises a data line and a MICROUSB male plug or a TYPE-C plug connected to the outer end of the data line; the control part comprises a decoding sound effect processing circuit and a sound reduction device, and the sound reduction device is connected to an earphone speaker or an AUX input end; the decoding sound effect processing circuit comprises a decoding output circuit and a sound effect processing circuit. The earphone and audio amplifier is reasonable in design, and the product requires no lithium battery or charging, thereby not only reducing the design cost, but also being green and environmentally-friendly. The production and assembly are convenient, the production efficiency can be greatly improved, the production reject ratio is reduced, and the production cost is reduced. The earphone and audio amplifier is high in practicability and thus is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of electronic products, and more specifically relates to an earphone integrating a DAC and a sound effect processing circuit. Background technique [0002] In 2016, with the global launch of the iphone7, there was a function change in Apple smartphones, which had to attract our attention. Apple took the lead in canceling the 3.5 headphone socket, in order to enhance the waterproof function. Following this trend, other brands of smartphones may also follow this concept and change their designs. [0003] After the cancellation of the 3.5 headphone jack, people's daily usage habits have been changed. Some people may choose Bluetooth headsets, but as we all know, Bluetooth headsets are high-frequency wireless audio receiving products. They are worn on the ears and relatively close to the human head. Due to the large electromagnetic wave radiation, they have an impact on human health. Contents of the invention [0004]...
