Embodiment

[0024] refer to figure 1 As shown, the present invention discloses a bluetooth earphone system based on audio distortion compensation technology, which includes a bluetooth receiving module, an electronic frequency division module, several loudspeakers and several physical frequency adjustment parts.

[0025] Wherein, the bluetooth receiving module receives the digital audio signal and converts the digital signal into an analog signal.

[0026] The electronic frequency division module is connected with the bluetooth receiving module, and the electronic frequency division module decomposes the analog signal into a very high-pitched electric signal, a high-pitched electric signal, a mid-range electric signal and a low-pitched electric signal.

[0027] The electronic frequency division module is provided with a resistor for adjusting the sound intensity and a capacitor for adjusting the lower limit of the sound frequency. Resistors can limit the amount of current, which determin...

Abstract

The invention discloses a Bluetooth headset system based on an audio distortion compensation technology, comprising a Bluetooth receiving module, wherein the Bluetooth receiving module receives the digital signal of the audio frequency and converts the digital signal into an analog signal; an electronic frequency dividing module connected with a Bluetooth receiving module, wherein the electronic frequency dividing module decomposes the analog signal into a very high-pitch electric signal, a high-pitch electric signal, a middle-pitch electric signal and a low-pitch electric signal; a pluralityof loudspeakers respectively connected with an electronic frequency dividing module to generate sounds of different frequency bands according to the extremely high-pitch electric signal, the high-pitch electric signal, the middle-pitch electric signal and the low-pitch electric signal; a plurality of physical frequency adjusting sections are respectively connected to the rear ends of the respective loudspeakers and used for controlling the sound producing frequency of the loudspeakers. The invention can compensate the sound distortion of the Bluetooth headset and realize the high-quality soundoutput of the Bluetooth headset.

Description

technical field [0001] The invention relates to the technical field of bluetooth earphones, in particular to a bluetooth earphone system based on audio distortion compensation technology. Background technique [0002] Bluetooth headset is to apply Bluetooth technology to hands-free headsets, so that users can avoid annoying wires and talk easily in various ways. Since the advent of Bluetooth headsets, it has been a good tool for mobile business families to improve efficiency. At present, with some mobile phones canceling the 3.5 headphone jack, and the pursuit of convenience and speed, people are becoming more and more enthusiastic about Bluetooth headsets. [0003] However, the Bluetooth transmission process easily causes audio signal loss and distortion; and due to the insufficient driving capability of the Bluetooth circuit, this further aggravates the sound distortion and cannot achieve high-quality HIFI sound characteristics. Contents of the invention [0004] The t...
