Apparatus and electronic device for inducing brain wave

A brain wave inducing apparatus, comprising:

• a crystal oscillator configured to generate clock signals;
• a frequency convertor configured to convert frequencies of the clock signals into a predetermined range to generate electrical signals;
• an output unit configured to receive and transmit the electrical signals from the frequency convertor;
• at least one sensor electrically coupled to the frequency convertor via the output unit and attached to a human body, the at least one sensor configured to generate vibration at a predetermined frequency in response to the electrical signals transmitted from the output unit, and transfer the vibration to the human body to induce a human brain attached to the human body to generate brain waves with substantially the same frequency of the electrical signals and the vibration.

An electronic device, comprising:

• a main body configured to generate electrical signals, the main body comprising:
• a crystal oscillator configured to generate clock signals;
• a frequency convertor configured to convert frequencies of the clock signals into a predetermined range to generate the electrical signals;
• an output unit configured to receive and transmit the electrical signals from the frequency convertor;
• and
• an earphone detachably and electrically coupled to the frequency convertor via the output unit, the earphone comprising an earpiece and at least one sensor attached to the earpiece, the at least one sensor generating vibration with a frequency in the predetermined range in response to the electrical signals.
