Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] In the induction technology, the binaural short-sound stimulation signal is to control the output frequency of the left and right channels in turn according to the set alpha wave frequency of the input short-sound audio signal, and then act on the left and right sides of the human body respectively. The right two ears form a changing sound field in the left and right auditory organs of the user, and the purpose of inducing the user's brain wave synchronization is achieved through the changing frequency of the sound field. As we all know, the hearing of the left ear stimulates the right brain, and the hearing of the right ear stimulates the left brain. This sound field that changes according to the set frequency between the left and right brai...

Abstract

The invention relates to a bone conduction earphone based on dual-channel frequency difference and short sound stimulation double actions; wherein a control circuit comprises an input interface of a sound frequency analog signal, two analog-to-digital converters for carrying out analog-to-digital conversion to an interface output signal, a sound frequency signal processor which receives the output of the analog-to-digital converters and carries out segment treatment of frequency difference of left and right sound channels and short sound stimulation, two digital-to-analog converters, a power amplifier and two bone conduction earphones; the sound frequency signal processor is a field programmable gate array and is connected with a liquid crystal display, a keyboard and a memorizer, and carries out display control to the liquid crystal display and makes response to a control signal of the keyboard respectively. The earphone utilizes the comprehensive effect of combination of the frequency difference of the dual channels and the short sound stimulation to induce brain waves of users, and can be used as a sound frequency broadcasting device matched with a computer or a learning machine, so as to lead students to study effectively under relax state, and other auditory systems are not damaged.

Description

technical field [0001] The present invention relates to a bone conduction earphone with a novel structure and hearing protection function, to be precise, it relates to a brain wave-induced bone conduction based on the combination of binaural frequency difference and short tone stimulation. An earphone belongs to the technical field of audio output equipment. Background technique [0002] There is a magnetic field in everyone's body. When a person is thinking, the magnetic field will change, forming a magnetic field through which biological currents pass, that is, "brain waves." According to the current research results, the frequency of this spontaneous rhythmic nerve electrical activity ranges from 1 to 30 Hz, and can be divided into the following four bands. [0003] The 6 waves with a frequency of 0.4 to 4 Hz have the effect when they are the dominant brain waves: people are in a deep sleep and unconscious state, that is, a dreamless sleep state. [0004] The theta wave...
