Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a vibration generator that allows a human body to sense vibration generated by a combination of an electromagnet and a permanent magnet for external information.

[0002]

2. Description of the Related Art Conventionally, there are two methods of detecting the reception of external information such as radio waves by sound and those by vibration, and the sound is notified by a high frequency sound such as a piezoelectric buzzer. He is harassed for reasons such as giving trouble to others. In addition, the only thing that can be notified by vibration is a pager motor that has a "weight" attached to the tip of the motor shaft so that there is only one type of vibration.

[0003]

[Problems to be solved by the invention]

I. The method of notifying by sound as a method of detecting reception of radio waves causes annoyance to others. B. When a method of notifying the reception of electric waves by vibration is used, that is, when a pager motor is used, the bearing portion of the motor is easily worn and there is a problem in terms of durability. C. The frequency cannot be changed. D. Noise is likely to occur. E. There are many parts. The present invention has been made to solve the above drawbacks.

[0004]

[Means for Solving the Problems] A wire (2) having good conductivity is wound around a ferromagnetic core (1) to form an electromagnet. A permanent magnet (4) is placed in a non-magnetic material container (3), and a non-magnetic material vibrating plate (5) is attached near the magnetic poles of an electromagnet. The switch is turned on by catching radio waves and other external information, and at the same time, the N, S conversion circuit of the electromagnet is activated to generate vibration. The present invention is a miniature vibration generator having a combination of an electromagnet and a permanent magnet having the above structure.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION When the present invention is used, external information such as radio waves can be caught and vibrations can be sensed by receiving the device alone or by simply installing it in a mobile phone or pager. It is a form to convey.

[0006]

Embodiments of the present invention will be described below. (A) A wire (2) having good conductivity and coated with urethane, varnish or the like is wound around the ferromagnetic core (1) to form an electromagnet. (B) A permanent magnet (4) is placed in a container (3) made of a non-magnetic material such as plastic, and non-magnetic vibrating plates (5) are provided above and below it. (C) Install a container containing a permanent magnet near the magnetic poles of the electromagnet. (D) The present invention is installed alone or in a mobile phone or pager. (E) A circuit is incorporated in which the switch is turned on by simultaneously catching radio waves and other external information, and at the same time, the N and S poles of the electromagnet are converted. (F) When the control signal is input to the oscillator circuit (6), the phase-shifted pulse signals of the A-phase (9) and the B-phase (10) are alternately turned on and off at a constant cycle. When the A phase is turned on, the permanent magnet (4) has the S pole of the N pole electromagnet, and conversely S pole
Since the pole is attracted to the N pole, the permanent magnet (4) hits the vibrating plate (5) provided on the top and bottom of the non-magnetic container (3) holding the permanent magnet (4) to generate vibration.
See (Fig. 7). When phase B is ON, the magnetic pole of the electromagnet is A
Since it is the reverse of the case where the phase is turned on, it becomes as shown in FIG. As described above, while the control signal is being input to the transmitting circuit (6), the A phase (9) and the B phase (1
Since the pulse signal of 0) is alternately turned on and off, the N and S poles of the permanent magnet (4) are attracted to the S and N poles of the electromagnet along with the conversion of the N and S poles of the electromagnet, and the diaphragm ( Continue to vibrate against 5). (G) When the control signal input to the transmission circuit (6) is turned off, the pulse signals of the A-phase (9) and B-phase (10) are also stopped, so that the magnetic field lines do not occur in the electromagnet, so the permanent magnet (4)
Becomes stationary and does not vibrate. The present invention is a miniature vibration generator having a combination of an electromagnet and a permanent magnet having the above structure. When the present invention is used, it is switched on by catching radio waves and other external information by itself or by simply installing it in a mobile phone or pager, and at the same time, the N, S conversion circuit of the electromagnet is turned on. Activates to generate vibration. In addition, since the present invention can utilize various vibrations that are generated by catching various signals, converting the N and S poles of the electromagnet, and attracting the N and S poles of the permanent magnet, only the person concerned does not disturb others. Widely used in the fields that need to sense information.

[0007]

By using the present invention, external information such as reception detection of radio waves is caught and transmitted as vibration, so that it does not cause trouble to others as compared with the case of transmitting by sound. Also, compared to a pager motor that transmits by vibration, it is superior in terms of durability, less noise generation, variable frequency, and fewer parts.
