Abstract

(57) [Summary] [Purpose] A vibration generating motor that generates vibrations that can be felt by the human body by rotating a weight as the drive motor rotates. It is an object of the present invention to obtain a vibration generating motor that has a low weight rotation noise. [Structure] A weight 1 made of a material with a high specific gravity and having a semicircular shape is attached to a coil support plate 2 that is fixed to the inner peripheral surface of the tip of the coil 3 that forms the rotor part of the drive motor. This is a vibration generating motor that is attached to one half of the support plate 2 and has a rotor part that is entirely enclosed and sealed with an outer peripheral case.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a vibration generation mode for a mobile transmitter/receiver that uses the human body to sense vibrations and make calls. This is related to data.

0002

[Conventional technology]

The conventional vibration generating motor is a cylindrical drive motor with a long tube, as shown in Figure 3. A rotor that protrudes from the end surface 6 of the outer case 5 that surrounds and seals the entire rotor part. A weight 1 having a semicircular shape is fixed to a shaft 4, and the rotational movement of the weight 1 causes It generates vibration.

0003

[Problem that the idea aims to solve]

In conventional vibration generating motors, the mounting point of the weight that generates vibration is Because the drive motor is placed outside the outer case, the length of the vibration-generating motor is , the problem was that it was longer and larger than the driving motor. . In addition, the rotation noise generated by the rotation of the weights is transmitted directly to the surrounding area, making it unpleasant for the people around you. There was a problem with giving a feeling.

0004 This invention has a compact shape with a length comparable to that of the drive motor, and has a low weight rotation noise. The purpose is to provide a motor that generates small vibrations.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, in the vibration generating motor of the present invention, the drive motor It is fixed to the inner peripheral surface of the tip of the coil that makes up the rotor part of the motor, and is attached to the rotating shaft of the motor. A semicircular weight is attached to a fixed cylindrical coil support plate.

[0006] In other words, the vibration generating motor of the present invention rotates the weight in conjunction with the rotation of the drive motor. In vibration-generating motors that generate vibrations that can be detected by the human body, A semicircular weight made of a material with a high specific gravity is attached to the tip of the coil of the drive motor. It is characterized by being attached to one half of the coil support plate that is fixed to the inner peripheral surface of the This is a vibration generating motor.

[0007]

[Effect]

In conjunction with the rotation of the coil of the vibration generating motor configured as above, the conventional coil The semicircular weight attached to the coil support plate, which is fixed to the coil, rotates. The vibration generation motor vibrates due to the rotational movement of the Occurs on a regular basis. In addition, the rotor part, which consists of a coil support plate with weights attached, etc. The entire structure is enclosed and sealed by the outer case of the vibration generating motor, so the sound of the rotating weight is removed from the outside. This prevents information from being transmitted to other departments.

【Example】

Embodiments of the present invention will be described with reference to the drawings. Figure 1 shows the vibration generated by this invention. It is a perspective view of the rotor part of a motor. In Figure 1, the rotor section of the drive motor is configured. The coil support plate 2 is fixed to the inner peripheral surface of the tip of the coil 3 wound into a cylindrical shape. Attach a weight 1 made of tungsten with a large specific gravity and having a semicircular shape. There is. Further, a rotating shaft 4 is fixed to the center of the coil support plate 2 by passing through the coil support plate 2. It is worn.

[0009] Figure 2 shows the installation of the rotor part with weights attached to the coil support plate of the present invention. FIG. 2 is a perspective view of a vibration generating motor according to the present invention; The entire rotor portion is surrounded and sealed by a cylindrical outer peripheral case 5.

[Effect of the idea]

Since the present invention is configured as explained above, the following be effective. The coil support plate that makes up the rotor of the drive motor is A vibration-generating motor that generates vibrations by attaching a weight that generates vibrations. The length of the motor is the same as that of a conventional drive motor, allowing the vibration generating motor to be made smaller. Ru. In addition, the weight attached to the coil support plate is surrounded by an outer case and sealed. This prevents the rotation noise generated by the rotation of the weight from being transmitted to the outside. Therefore, the shape is small, the rotation noise is low, and the vibration generates vibrations that can be detected by the human body. We can provide a generating motor.
