PORTABLE DEVICE AND VIBRATION GENERATOR SYSTEM MOUNTED FOR THE STATE INFORMATION
Document Type and Number:
Japanese Patent JP2003145049
Kind Code:
A
Abstract:
To reliably transmit the vibration of a vibration generator body to a portable device.
The vibration generator system 3 having a vibration generator body 10 formed by attaching an eccentric weight 9 on the rotary shaft 8 of a motor 7 is installed inside a case 1 through an elastic body 6. An elastic modulus is set so that the elastic body 6 resonates with the vibration of the vibration generator body 10. Accordingly, the vibration of the vibration generator body 10 is transmitted to the case 1 in such a manner that the vibration is amplified by the resonance action of the elastic body 6.
