Technical Field
The invention relates to the field of biomedicine and music, in particular to a Bluetooth headset for playing alpha wave music.
Background
Brain waves are the signals of potential changes produced by the spontaneous rhythmic neuroelectrical activity of a large number of neurons of the cerebral cortex. Brain waves can be divided into four categories, i.e., delta waves, theta waves, alpha waves, and beta waves:
beta brain waves: 14-40 Hz, the brain is in a tense state, is sensitive to the surrounding environment, is difficult to concentrate, and is easy to fatigue. Most people are in this state while awake;
alpha brain waves: 8-14Hz, the brain is in a relaxed state, is awake and relaxed, is easy to concentrate on learning and work, is not easily interfered by external objects, and is not easy to be tired. The general people need to train for a long time to adjust the alpha wave state, otherwise, the alpha wave state is difficult. The alpha brain wave frequency band is currently concerned by enhancing memory, improving learning effect and treating insomnia;
theta brain waves: 4-8Hz, the computer is in a deep and relaxed state, the attention is highly concentrated, the inspiration is increased, and the creativity is high. The general people can be consciously adjusted to the theta state after long-term training, otherwise, the theta state is difficult to adjust;
delta brain waves: 0.5-4 Hz, the computer is in a sleep state, and people can appear in a deep sleep state.
Obviously, the influence of music on brain waves can be achieved by music and brain wave adaptation. Particularly, by adding or simulating alpha brain waves in music, it is possible to improve the work efficiency and creativity of the brain, reduce tension, stress and anxiety, improve immunity, etc. through the alpha brain waves and music stimulation.
The alpha wave music can bring people into an alpha brain wave state, and can be used for developing brains, enhancing memory, exciting potential, improving concentration, stabilizing emotion, improving sleep, eliminating fatigue and coordinating body and mind.
The α waves are subdivided into three categories:
slow α wave: 8-9 Hz, a state of being in a loss of mind before sleep;
intermediate alpha wave: 9-12 Hz, inspiration, intuition or click can exert the state of power, and the body and mind are relaxed and the attention is focused;
fast alpha wave: 12-14 hz, high alertness, and absence of patronage.
In order to solve the above problems, the present invention discloses an alpha wave music bluetooth headset for generating and playing alpha waves and combining the alpha wave music with the played music to form an alpha wave music effect, thereby enabling a music appreciator to achieve mental benefits obtained by enhancing personal alpha brain waves while listening to alpha wave music.
