The central portion of the lower surface of the second plate-like elastic body 2 has a size that is located between the two sides and can be arranged at a location where the magnetic flux density of the magnetic field generator 7 including the yoke 3 and the plate-like magnet 4 is high. It projects from below.

されている。A pulse signal for repeating energization and de-energization is applied from the CPU 10 to the transistor 9, and a current having the same frequency as the frequency of the pulse signal flows through the rectangular cylinder coil 5. When the rectangular tube coil 5 is energized in this manner, the plate magnet 4
The yoke 3 provided with and the rectangular tube coil 5 vibrate by electromagnetic force, and as a result, the first vibrating system and the second vibrating system vibrate. The CPU 10 is configured so that the frequency of the pulse signal can be selected from a first frequency that resonates the first vibration system and a second frequency that resonates the second vibration system.

しを行うことが可能となる。When the CPU 10 applies a pulse signal of the first frequency to the transistor 9 to cause the vibration generator to vibrate at 100 Hz in accordance with the resonance frequency of the first vibration system, the first plate-shaped elastic body 1 The device itself resonates in synchronism with the above-mentioned resonance frequency via the, and sensation vibration is generated. As a result, it is possible to make a silent call that does not disturb others.

作用を営む。On the other hand, the CPU 10 gives a pulse signal of the second frequency to the transistor 9, so that the vibration generator is set to 2.7 in accordance with the resonance frequency of the second vibration system.
When vibrating at a frequency of kHz, the device itself resonates in synchronization with the resonance frequency, generates a ringing sound, and functions as a speaker.

かつ振動発生装置の質量の大部分を占める磁界発生体７
が第１の振動系に属するために、第１の振動系の質量が
大きくなっているからである。Here, the resonance frequency of the first vibration system is the second frequency.
Is lower than the resonance frequency of the vibration system, the spring constant of the first plate-like elastic body 1 forming the first vibration system is small,
And the magnetic field generator 7 that occupies most of the mass of the vibration generator
Is belonging to the first vibration system, the mass of the first vibration system is large.

め、第２の振動系の質量が小さいからである。On the contrary, the reason why the resonance frequency of the second vibration system is relatively high is that the second plate-shaped elastic body 2 constituting the second vibration system is used.
This is because the second vibrating system has a large spring constant and the second vibrating system is composed of only the rectangular tube coil 5 having a small mass and the second vibrating system, and thus the second vibrating system has a small mass.

のみ身体に伝えることができるからである。It is preferable to set the resonance frequency of each vibrating system so that the frequency of the body vibration caused by the first vibrating system is 250 Hz or less and the frequency of the ringing sound is 600 Hz or more in the second vibrating system. . The reason why the frequency is set to 600 Hz or more is that ISO 226 (196)
This is because, based on the equal loudness curve of 1), it is possible for human ears to hear at a low sound pressure level when vibrating at 600 Hz or higher. That is, a sound that can be heard by the human ear can be generated with low vibration energy. Further 250Hz
The following is based on the same loudness curve as well.
This is because vibrations of 0 Hz or less cannot be heard by the human ear and only mechanical vibrations can be transmitted to the body.

Then, for example, the pager carrier can be configured to select either the ringing sound or the sensible vibration with the changeover switch. It is also possible to alternately generate the pulse signal of the first frequency and the pulse signal of the second frequency from the CPU 10 at regular time intervals so that both the ringing sound and the sensory vibration are generated alternately. .
