Abstract

The embodiment of the invention provides a terminal, a noise reduction earphone and an earphone noise reduction method. The terminal comprises a first microphone and a processor, and is characterized in that the first microphone is used for acquiring noise in the environment and converting the noise into external noise signals; the processor is used for receiving reference audio signals sent by the noise reduction earphone, wherein the reference audio signals are acquired according a reference audio frequency, and the reference audio frequency is an audio frequency, which is acquired by a second microphone arranged in an earmuff of the noise reduction earphone, in the earmuff; the processor is further used for generating noise correction signals according to the reference audio signals and the external noise signals and generating play signals according to input audio signals and the noise correction signals; and the processor is also used for sending the play signals to the noise reduction earphone so as to enable the noise reduction earphone to convert the play signals into a play audio frequency. According to the invention, the cost and the weight of the noise reduction earphone can be reduced.

Description

technical field [0001] The invention relates to signal processing, in particular to a terminal, a noise reduction earphone and a noise reduction method for the earphone. Background technique [0002] Earphones are a conversion unit that converts electrical signals into audible sound waves. One of the benefits of using earphones is that they can isolate the noise of the surrounding environment. In people's various listening environments, the sound greater than 90dB and which people cannot accept subjectively is generally called noise. The generation and existence of noise is inevitable, and noise will seriously affect the feelings and mood of the audience. [0003] Noise-cancelling headphones can eliminate noise to a certain extent and improve people's listening experience. Noise-cancelling headphones are divided into passive noise-cancelling headphones and active noise-cancelling headphones. Passive noise-cancelling headphones usually use special sound-insulating materials ...
