What Is a Headphone Amp?

Headphone Amplifier (English: Headphone Amplifier) is a kind of amplifier. It is an audio amplifier specially designed to drive headphones. Headphone amplifiers generally appear as integrated circuits in electronic devices, music players, and televisions, but there are also separate headphone amplifiers.

Headphone Amplifier

Amplifier (English: Amplifier ), commonly known as a speaker , generally refers to any device that can use less energy to control larger energy

Headphones, also called earphones or earphones , are a pair of conversion units.

Integrated circuit (English: integrated circuit, abbreviation: IC; German: integraler Schaltkreis), also known as microcircuit , microchip, chip / chip (chip) in electronics is a kind of circuit (mainly including Semiconductor devices, including passive components, etc.) are miniaturized and often manufactured on the surface of semiconductor wafers.

The aforementioned integrated circuit in which a circuit is manufactured on the surface of a semiconductor chip is also referred to as a thin-film integrated circuit. Another type of thick-film integrated circuit (hybrid integrated circuit) is a miniaturized circuit composed of independent semiconductor devices and passive components integrated into a substrate or a circuit board.

From 1949 to 1957, Werner Jacobi, Jeffrey Dummer, Sidney Darlington, Yasuo Tarui all developed Prototype, but modern integrated circuits were invented by Jack Kilby in 1958. He was awarded the 2000 Nobel Prize in Physics, but Robert Noyce, who also developed modern practical integrated circuits at the same time, died as early as 1990. ^[1]
