Problems solved by technology

[0005] However, in the vibration motor of Patent Document 1, since the eccentric weight is fixed on the top end of the motor shaft, the length of the eccentric weight (dimension along the motor shaft) is limited, and in order to obtain sufficient vibration, a certain volume must be ensured. , so the radial size of the eccentric hammer should exceed the radial direction of the motor
For this reason, there is a problem that the installation space of the vibration motor will be too large
[0006] On the other hand, once the radial direction of the eccentric hammer is reduced, the weight of the eccentric hammer will be reduced, and it may not be possible to obtain sufficient vibration.

Embodiment Construction

[0039] Below, refer to the attached Figure 1 ~ Figure 4 , the first embodiment of the present invention will be described in detail. The vibrating device 1 according to the first embodiment is a vibrating device mounted in a mobile phone or the like that generates vibrations.

[0040] This vibration device 1 such as figure 1 and figure 2 As shown, there is a casing 5 and a motor 7 and an eccentric weight 9 held in the casing 5 .

[0041] The casing 5 is divided into a front casing portion 5 a and a rear casing portion 5 b, and these are fitted and fixed to form an annular casing 5 . The front side casing part 5a is comprised by the front side wall part 6a, and the left and right side wall parts 6b, 6c which protrude from the front side wall part 6a at right angles to the rear side. Fitting recesses 6d are formed on the left and right side wall portions 6b, 6c. Similarly, the rear cabinet part 5b is comprised from the rear side wall part 8b, and the left and right side w...

Abstract

The present invention provides a vibration device and a mobile terminal. When horizontally arranging a motor, the space of the height direction can be reduced, and enough vibration can be obtained. The invention is provided with a motor body (19), a motor shaft (21) for configuring the motor body (19), an eccentric weight (9), a weight shaft (23) for fixing the eccentric weight (9), and shaft bearings(13a,17a) of the weight shaft (23). The motor shaft (21) and the weight shaft (23) are arranged in parallel, the motor body (19) and the eccentric weight (9) are arranged in parallel, the motor shaft (21) is connected with the weight shaft (23) through the transmission mechanism (3) to transmit rotation of the motor shaft (21) to the weight shaft (23).

Description

technical field [0001] The present invention relates to a vibration device that generates vibration when a mobile phone or the like receives a call, and is used in a game device or the like, and a mobile terminal equipped with the vibration device. [0002] The so-called mobile terminal device includes a mobile phone, a PDA, a notebook computer, and the like. Background technique [0003] Patent Document 1 (JP 2008-199754 A) discloses a vibration motor in which an eccentric weight is fixed to the tip of a motor shaft. [0004] For this type of vibrating motor, it is required to be more miniaturized, especially when the motor is placed on a horizontal position, the height of the motor is reduced when it is installed on the machine. [0005] However, in the vibration motor of Patent Document 1, since the eccentric weight is fixed on the top end of the motor shaft, the length of the eccentric weight (dimension along the motor shaft) is limited, and in order to obtain sufficien...
