2. Description of the Related Art Small devices such as portable communication devices are provided with, for example, notification means for notifying an incoming call, notification of a predetermined time, and the like. Many. However, in recent years, in consideration of surrounding people, in addition to the sound notification means, a notification means by vibrating the device is built in, and depending on the situation, both notification means are used, or either of them is used. There is an increasing number of small devices that selectively use the notification means. For example, FIG.

In such a conventional technique, it is common that the sound notification means and the vibration notification means are respectively built in the device. In this case, two separate notification means are required, which hinders downsizing of the device. There was a problem of doing.

[0003] For this reason, the present applicant has invented a vibration generating device for notification having both functions of notification by sound and notification by vibration, and has already filed an application as Japanese Patent Application No. 8-161399.

In the present embodiment, the lower case 110a supporting the first vibration system
And an upper case 110b that supports the second vibration system and is coupled to the lower case 110a.
Two vibration systems are housed in a space formed inside by the connection of the upper case 110a and the upper case 110b. Upper case 11
An opening 111 for transmitting sound waves to the outside is open at the center of 0b.

The first vibrating system includes a first spring body 112 formed by using an elastic material such as a thin metal plate, rubber, resin, or the like so as to be deformable in a direction perpendicular to the surface, and a first vibrating body having a permanent magnet 113. The first vibrating body 116 is attached to the inner peripheral side of the first spring body 112 by bonding or the like.
The outer peripheral side of the first spring body 112 is attached to the lower case 110a by bonding or the like. Thus, the first vibration system can vibrate up and down with respect to the lower case 110a. The first vibrating body 116 including the permanent magnet 113 has a permanent magnet 113 to prevent leakage of a magnetic field to the outside and to efficiently generate an electromagnetic force acting by the interaction between a current and a magnetic field.
An upper yoke 114 and a lower yoke 115 are provided above and below, respectively, thereby forming a magnetic circuit. The permanent magnet 113 is formed in an annular shape such that the upper surface has an N pole and the lower surface has an S pole. The upper yoke 114 is formed in a ring shape having a vertical wall on the inner periphery. Is formed in a disk shape having a raised portion. Upper yoke 11
4 and the central ridge of the lower yoke 115,
A magnetic gap 121 is formed such that a second vibrating body 117 described later can move up and down.

On the other hand, the second vibration system includes a second spring body 122 formed by using the same elastic material as the first spring body 112 so as to be deformable in a direction perpendicular to the surface, and a second vibration system.
The second vibrating body 117 is attached to the inner peripheral side of the second spring body 122 by adhesion or the like, and the outer peripheral side of the second spring body 122 is attached to the upper case 110b by adhesion or the like. Thereby, the second vibrating body 1
17 can vibrate up and down with respect to the upper case 110b. The second vibrating body 117 includes a coil 118, the coil 11
8 and a vibration plate 120 for generating a sound wave. The bobbin 119 has a cylindrical shape, and is attached to the second spring body 122.
A coil 118 is wound around the outer periphery of the coil 19. Bobbin 1
A diaphragm 120 is provided on the upper surface of the module 19. Coil 1
18 and the hobbin 119 are provided so as to be movable in the magnetic gear 121 of the first vibrating body 116. Note that 123 is a terminal of the coil 118, and 124 is a cushioning material such as rubber.

[0007] As described above, the lower case 110a and the upper case 110b in which the respective vibration systems are provided are connected to each other, and the coil 1
The 18 terminals 123 are electrically connected to a circuit (to be described later, not shown in FIG. 6) for flowing a current having a set predetermined frequency. At this time, in the first vibrating body 116, the permanent magnet 1
13, a magnetic circuit including the upper yoke 114, the lower yoke 115, and the magnetic gap 121 is formed.
The magnetic field in 21 is radially inward. Also, coil 1
Assuming that the direction of the current flowing through 18 is counterclockwise as viewed from above, the interaction between the magnetic field and the current intersecting the magnetic field causes the first vibrating body 116 and the second vibrating body 11 to rotate.
Repulsion works between 7. Conversely, if the direction of the current flowing through the coil 118 is reversed, an attractive force acts between the first vibrating body 116 and the second vibrating body 117. Therefore, by periodically changing the value of the current supplied to the coil 118, a periodic electromagnetic force is applied as an external force to each of the first vibrating body 116 and the second vibrating body 117.
By means of the coil 13 and the coil 118, forced vibration can be generated in each of the first vibration system and the second vibration system.
Due to this forced vibration, the first vibration system causes the first vibration body 11
6 can be caused to collide with the case 110, or the vibration can be transmitted to the case 110 by the restoring force of the first spring body 112 to cause the device to vibrate, thereby providing notification by the vibration. Further, due to this forced vibration, the second vibration system causes the diaphragm 120 of the second vibrating body 117 to vibrate the air to generate a sound wave, which propagates to the outside through the opening 111 of the upper case 110b. I do. The frequency of the sound wave is in the audible range (about 20 Hz
If it is about 20 kHz), notification by sound can be realized.

FIG. 8 is a graph showing the amplitude characteristics of the vibrating body with respect to the frequency of the current flowing through the coil 118 in such a vibration generating apparatus. The first vibrating body 116 and the second vibrating body 117 are different from each other. It has a frequency and its amplitude is configured to be maximum at 100 Hz and 3 kHz, respectively.
