Problems solved by technology

However, it is difficult to obtain large vibrations with a reduced hammer size
On the other hand, when the hammer is enlarged, a larger vibration can be obtained, but the start-up time before the vibration becomes longer

Abstract

The utility model provides a vibration generation device. The vibration generation device comprises a motor, a hammer and a pair of springs. The motor makes a keeping body supported to rotate with a hypothetical central axis as the center to conduct reciprocating rotational motion within a specified rotation angle range. The hammer is kept by the keeping body in the state that the hammer is eccentric relative to the hypothetical central axis. One spring in the springs applies force to the keeping body in the keeping body rotation direction, and the other spring applies force to the keeping body in the direction opposite to the keeping body rotation direction. The vibration generation device is characterized in that the spring constants of the springs, the mass of the hammer and the vibration frequency of reciprocating rotational motion are set to be values making the keeping body resonate respectively.

Description

technical field [0001] The present invention relates to a vibration generating device, and more specifically relates to a vibration generating device in which a holding body holding a hammer rotates back and forth at a predetermined rotation angle to generate vibration. Background technique [0002] Vibration generating devices are used in various electronic devices such as mobile phones, portable terminal devices, and tablet PCs. For example, a vibration generating device built into a mobile phone notifies the user of an incoming call by generating vibrations. In addition, the vibration generating device built into the tablet computer can confirm whether the operation to be performed is surely performed by generating vibration when a finger or a pen is in contact with the screen. Various techniques have been proposed so far for such a vibration generating device. [0003] The vibration generating device described in Japanese Laid-Open Publication No. 2010-179295 is a line...
