Amplifiers; audio-frequency electric

HS v2017 Code: 851840

About amplifiers; audio-frequency electric

hs code 851840 covers a crucial component in the audio and electronics industry - audio-frequency electric amplifiers. These devices play a vital role in boosting and modulating electrical signals, enabling the amplification of sound, music, and various electronic signals. As a key part of sound systems, audio equipment, and communication technologies, amplifiers described by this code are essential for the proper functioning and performance of a wide range of consumer and industrial products.

Production process

The production of audio-frequency electric amplifiers involves several key steps. First, the core electronic components, such as transistors, resistors, and capacitors, are assembled onto a printed circuit board. The circuit design is carefully engineered to provide the desired amplification characteristics. The housing or casing is then manufactured, often from durable materials like metal or plastic, to protect the internal components. Finally, the amplifier is tested, calibrated, and prepared for distribution.

Production inputs

The main inputs required for the production of 851840 Amplifiers; audio-frequency electric include electronic components like transistors, integrated circuits, resistors, and capacitors. Specialized manufacturing equipment, such as circuit board assembly machines and testing equipment, are also essential inputs. Additionally, the industry relies on raw materials like metals, plastics, and other materials used in the construction of the amplifier housing and casing.

Production outputs

The primary output of the 851840 Amplifiers; audio-frequency electric industry is, of course, audio-frequency electric amplifiers. These amplifiers are then consumed by a wide range of industries, including 852110 (Television receivers (including video monitors and video projectors), whether or not incorporating radio-broadcast receivers, sound-recording or sound-reproducing apparatus), 851810 Microphones and stands therefor, 851830 Headphones, earphones and combined microphone/speaker sets, and 851920 Transmission apparatus for radio-telephony, radio-telegraphy, radio-broadcasting or television, whether or not incorporating reception apparatus or sound recording or reproducing apparatus; television cameras; digital cameras and video camera recorders.
