Problems solved by technology

[0006] However, in addition to the need for an expensive spot welding machine, spot welding also needs to remove the dross or burrs generated during welding to prevent the dross or burrs from adversely affecting the circuit operation or the rotation of the motor.
In particular, when the motor housing is deformed by spot welding, it hinders the rotation of the motor
[0007] On the other hand, in recent years, miniaturization, thinning, and weight reduction are gradually required for portable communication devices or game machines. Vibration motors are also required to be miniaturized without exception, but there is a limit to miniaturization in order to generate the necessary amount of vibration

Embodiment Construction

[0035] Embodiments of the present invention will be described below using the drawings.

[0036] FIG. 1 is a perspective view showing a disassembled structure in which a vibration motor used for generating vibrations of a portable communication device is held on a circuit board.

[0037] In Fig. 1, 1 is the vibrating motor main body that surrounds with cylindrical motor frame, and 10 is the eccentric weight that the vibration generation that is fixed on the rotating shaft 11 of vibrating motor main body 1 uses, and 2 is to surround vibrating motor main body 1. The retainer that is held in a peripheral manner, the vibration motor main body 1 is held by surrounding the whole with the retainer 2 from the outside in the state where the eccentric weight 10 is installed, and is inserted and installed in the cutout space 31 of the circuit board 3 . Resin bracket 12 is fixed on the rear end (right end in the figure) of vibration motor main body 1, and external terminal 13 of conducti...

Abstract

There is provided a holding structure to hold a vibration motor on a circuit board with a sufficient holding strength using an inexpensive and simple means such as caulking and bonding and a vibration motor held on a circuit board using the holding structure. The holding structure having a holder clamps a vibration motor body having an eccentric weight at an end of the rotation shaft around the outer periphery from the outside and supports the vibration motor at the lower part.

Description

technical field [0001] The present invention relates to a holding structure of a vibration motor which is built in a portable communication device such as a mobile phone or a PHS or a game machine, and which generates vibration for somatosensory use, and a vibration motor provided with the holding structure. Background technique [0002] It is known that when a portable communication device has an incoming call, a ringtone is sent to notify the carrier of the call. In addition, there is a method of making the carrier feel the vibration caused by the rotation of the eccentric weight of the built-in vibration motor to notify the caller. method, they can be switched as needed. In addition, among game machines, there are machines that transmit vibrations generated by vibration motors in the machines to the operator in accordance with the progress of the game to improve entertainment. [0003] This kind of vibration motor is fixed on the circuit board in the machine, and the vib...
