Description

[0001] Audio Apparatus for Health care [0002]

The present invention relates to an audio apparatus for a healthcare, and more particularly, to an audio apparatus for a healthcare, and more particularly, to a sound apparatus for a healthcare apparatus which reproduces a sound in which various components are combined with ultrasonic components, And an audio apparatus for a health care having an excellent effect for improving concentration.

The human brain is known to emit different frequencies according to each state. If a signal of a certain frequency is continuously received from the outside, such as sound or light, the brain waves have the effect of synchronizing with the input frequency. In general, when the human brain is meditating, the mind and body are relaxed, and when the mind is concentrating, the brain becomes active.

Clinical experiments have revealed that the human brain produces different frequencies during activity, sleep, and meditation. These frequencies are generally referred to as brain waves and include alpha waves having a frequency range of 7 Hz to 11 Hz, beta waves having a frequency range of 15 Hz to 23 Hz and frequency ranges of 4 Hz to 6 Hz A delta wave? Having a frequency range of 0.4 Hz to 4 Hz is known.

Beta waves (β) are mainly observed when humans are active, and theta (θ) are mainly observed when humans are drowsy, and delta Wave (δ) is a waveform that appears mainly when a person is in a sleeping state or in a coma. Among these, it has been reported that the alpha-papa (alpha) has a predetermined therapeutic effect for modern people who are tired of various stresses, and there have been many attempts to artificially induce alpha papa (alpha) to help human activities.

Conventionally, as one of such attempts, a device for repeatedly generating a single tone sound has been developed in order to induce an alpha wave. However, in order to induce an alpha wave, a device having a frequency of 200 Hz to 1 KHz People started to show monotony and repulsion. In order to solve this problem, a device has been developed that mixes alpha or high frequency signals with a music signal so that the user can more effectively tune the brain function of the listener by listening to the music signal. However, due to the alpha or high frequency signals mixed in the music signal, However, there was a problem that it was distorted and perceived by the user.

In addition, in recent years, there is an attempt to utilize natural ultrasonic sound as another technique for inducing alpha waves. Ultrasound is a sound in the non-audible range and can not be heard in everyday life. Ultrasonic waves refer to frequencies above 22 kHz and these components are also called ultrasonic components. Ultrasound is divided into artificial and naturally occurring ultrasonic waves. The sound of waves is known to induce a sense of stability and alpha waves to humans. This is because the sound of waves is very supersonic. When these ultrasonic waves are combined with the sound of a wave, a very high frequency effect, which is a phenomenon that gives pleasure and increases the alpha wave and decreases the beta wave, appears.

However, in the case of using the natural sound including the ultrasonic wave to induce the ALPHA wave, there is a limit to continuous use due to boredom and monotony when it is repeatedly heard.

Although the music signal reproduced in the healthcare audio apparatus has been described as being stored in the memory unit 200 in the form of a music file, the music signal may be stored in the memory unit 200 in addition to the music file stored in the memory unit 200, It can be replaced. In this case, the selection unit 400 selects one of the music signal selected in the memory unit 200 and the external sound source signal 230 inputted from the outside according to the control of the control unit 100, .

The ultrasonic equalizer 900 is a component for setting a pass band of a selected ultrasonic signal in the memory unit 200 or for emphasizing or reducing a specific ultrasonic wave band component. More specifically, the ultrasonic wave equalizer 900 includes a memory unit 200 and an output unit 700, A passband is set so as to pass only a specific ultrasonic wave component among the ultrasonic components of the first ultrasonic signal selected in the first memory 210 of the memory unit 200, And provides it to the input of the output unit 700 after emphasizing or reducing the component. By using the ultrasonic equalizer 900, the user can more finely control the component of the ultrasonic signal reproduced together with the music signal.
