Embodiment Construction

[0026] Such as image 3 As shown, it is a wireless noise-cancelling earphone based on an intelligent mobile terminal of the present invention, including: a main body that transmits data by wireless signals between the wireless earphone part 10 and the intelligent terminal part 20;

[0027] (1) The wireless earphone part 10 includes a microphone 101 and a first signal sending module 102 electrically connected to the microphone 101, and a receiver 103, a signal playing module 104, and a first signal receiving module 105 electrically connected in turn;

[0028] The microphone 101 is used to collect noise signals, music and / or voice signals in the earphone, and sends them out of the earphone in a wireless manner through the first signal sending module 102; composite audio signal, and play in the earphone through the signal playing module 104 and the receiver 103;

[0029] (2) The smart terminal part 20 includes a second signal receiving module 201, a signal filtering module 202, ...

Abstract

The invention discloses a wireless noise reduction earphone based on an intelligent mobile terminal. The wireless noise reduction earphone comprises a wireless earphone portion and a mobile terminal portion, an acoustical signal including noise is picked up through a sound pick-up device built in the earphone and is sent to a mobile phone through a first signal sending module, signal processing is intelligently performed in the mobile phone through software, a noise signal is recognized, inverse phase and amplification control is conducted on the noise signal, meanwhile the amplitude, frequency response characteristic and other parameters of the signal can be further controlled, inverse noise signal and music signal superposition is obtained through processing, and the noise signal is sent back to the earphone along with the music signal in a wireless mode and is replayed along with the music signal through a loudspeaker. Therefore, the actively sent inverse noise signal is mutually offset with an environmental noise signal, and accordingly the noise reduction purposes are achieved.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a wireless noise reduction earphone based on an intelligent mobile terminal. Background technique [0002] The basic principle of traditional active noise reduction headphones is as follows: figure 1 shown. The external environmental noise (1) is picked up by the pickup (2) into an electrical signal, and then reversed and amplified by the controller (3), and then the loudspeaker (4) is used to replay a sound that is the same in size as the environmental noise (1) and opposite in phase. signal (5), the two signals cancel each other out, thereby eliminating the noise reaching the human ear. [0003] If the ANC headphones are small earbuds, such as figure 2 , because the space is limited and the controller cannot be placed inside the earphone (8), the controller will be placed on the signal line (6) to make an independent control box (7). [0004] Currently known noise-cancel...
