Embodiment Construction

[0032] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present invention and has no specific meaning by itself. Therefore, "module" and "component" may be used mixedly.

[0034] The present invention considers that the noise in the body is mainly transmitted in the body through bone conduction, so the embodiment of the present invention mainly aims at this part of the noise in the body, and proposes an active noise reduction scheme, by measuring the size and change trend of the noise in the body , to predict the noise in the body at the next moment, and then make a noise reductio...

Abstract

The invention discloses a noise-reducing device, an earphone and a noise-reducing method. The noise-reducing device comprises a bone induction pickup, a processor, a vibration source and a bone induction player, wherein the bone induction pickup is used for measuring a noise value in user body and transmitting the noise value to the processor; the processor is used for acquiring a change curve of the noise in body on the basis of the noise value measured by the bone induction pickup, forecasting the noise value at the next moment according to the change curve, getting an invert phase noise value of the noise value and then transmitting to the vibration source; the vibration source is used for generating an invert phase noise according to the invert phase noise value; the bone induction player is used for transmitting the invert phase noise into user body in a bone conduction manner. According to the invention, the noise-reducing device acquires the noise in user body in the manner of bone conduction, generates an invert phase sound wave of the noise in body and then transmits to human body in the manner of bone conduction, so that the noise in body is reduced or counteracted.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a noise reduction device, earphones and a noise reduction method. Background technique [0002] In daily life, many people have the habit of using headphones to listen to audio, and they can often be seen on buses and on the runways of parks. However, after strenuous exercise, heavy breathing sounds can become an important noise source, which in turn affects the effect of listening to audio with headphones. [0003] Traditional noise-canceling earphones are designed to reduce noise from outside the body, and there is no noise-reduction technology for noise inside the body. Therefore, how to provide a solution for active noise reduction according to changes in internal noise, so as to achieve the purpose of offsetting internal noise, has become a technical problem to be solved by the present invention. Contents of the invention [0004] The main purpose of the pr...
