Problems solved by technology

Because the existing power supply will be interfered by external induction to varying degrees, such as lightning strikes from nature, various communication broadcasts, radio transmissions, cars passing by nearby residents, electric equipment working, etc., all of which will affect the quality of our power supply
Indoors, the audio host and audio terminal equipment use insufficiently pure power, and the playback sound of the audio terminal equipment will be accompanied by certain noises, which will affect the listening effect
In the audio system in the car, the audio host is powered by the car battery. The power in the car battery is converted from the car engine to drive the power generation device, which is not pure enough, and its operating environment is much worse than the indoor operating environment. Audio The host is exposed to radiation for a long time, and the engine and other electrical equipment on the car simultaneously generate electromagnetic interference to the audio host, which seriously affects the replay quality

Abstract

The utility model discloses a processing circuit used for improving the performance of the audio equipment, and the processing equipment thereof. The processing equipment comprises a casing body, the input terminal interface of an audio host machine is arranged at one side of the casing body, the input terminal interface of a power supply is arranged at the other side of the casing body, a protective tube with filtering function is connected on the anode power wire of the input terminal of the audio host machine in series, and a capacitor is bridged between the anode power wire of the input terminal and the cathode power wire of the input terminal of the audio host machine. The processing equipment has the advantages that all sorts of harmful resonance in the circuit can be effectively restrained through the capacitor, and the capacitor plays the role of filtering; the protective tube with the filtering function can effectively restrain all sorts of harmful resonance in the circuit, and plays the role of filtering, reduces the impedance caused by vibration, and improves the degree of purity and the stability of the power supply, the higher harmonics components harmful to the signals are eliminated through the optimization of the quality of the power supply, and the powerful output capability is provided for the machine through the high-quality abundant electric current.

Description

technical field [0001] The invention relates to an audio processing device, in particular to a processing circuit and processing device for improving the performance of the audio device. Background technique [0002] The audio system includes an audio host, an audio signal line and an audio terminal device. The audio host is connected to the speaker terminal device through an audio signal line. The normal operation of the audio host requires an external power supply. The existing power supply will be interfered by external induction to varying degrees, such as natural lightning strikes, various communication broadcasts, radio transmissions, cars passing by near residents, electric equipment working, etc., all of which will affect the quality of our power supply. Indoors, the audio host and audio terminal equipment use an insufficiently pure power supply, and the playback sound of the audio terminal equipment will be accompanied by certain noises, which will affect the listen...
