Description

Vibrator structure of electronic device

The present invention relates to a vibrator structure of an electronic device.

The inside of the electronic device is generally provided with a vibration motor, which can generate vibration when an incoming call is made, so as to avoid interference with other people due to ringing of the incoming call in some occasions. Conventional electronic devices generally connect the vibration motor directly or indirectly on the main circuit board, and the electrical connection terminals of the vibration motor are electrically connected to the circuit of the main circuit board. For example, as shown in FIG. 1, a method for assembling a common vibration motor into a mobile phone by stacking a vibration motor on a circuit board and forming a guide between the vibration motor and the circuit board is shown in Chinese Patent No. 02399514.8. In addition, as shown in FIG. 3, the patent itself also introduces a method of assembling a vibration motor to a circuit board by connecting an vibration motor and a circuit board by using an electrical connector.

However, since the thickness of the vibration motor itself is large, stacking on the circuit board can increase the overall thickness of the electronic device. Therefore, the assembly method of the vibration motor stacked on the circuit board is disadvantageous to the overall thickness reduction of the electronic device. It is not conducive to the manufacture of thin and light electronic devices; in addition, since the vibration motor is stacked on the circuit board, it occupies a limited board space of the circuit board, which is disadvantageous for the layout of other electronic components, so that the space utilization rate of the circuit board is low.

In view of the above, it is necessary to provide an electron that can reduce the overall thickness of the electronic device. The vibrator structure of the device.

A vibrator structure of an electronic device includes a casing, a primary circuit board and a vibration motor. The casing is provided with a main circuit board and the vibration motor, and the vibration motor and the main circuit board of the electronic device are not formed. Stacked, the secondary circuit board is disposed on one side of the vibration motor and electrically connected to the vibration motor.

Compared with the prior art, the present invention can reduce the thickness of the electronic device and greatly save the surface of the circuit board by arranging the vibration motor on one side of the main circuit board and connecting the one side of the vibration horse through the primary circuit board. The layout space.

1 is an exploded view of a vibrating structure of an electronic device according to a preferred embodiment of the present invention; and FIG. 2 is an assembled view of a vibrating structure of the electronic device in accordance with a preferred embodiment of the present invention.

1 and 2, a vibrating structure 100 of an electronic device according to a preferred embodiment of the present invention includes a lower housing 10, a main circuit board 20, a vibration motor 30, a primary circuit board 40, and an upper housing 50.

A receiving slot 12 and a clamping slot 14 are defined in the lower housing 10 . The accommodating groove 12 is spaced apart from the clamping groove 14 by a partition wall 16 .

The main circuit board 20 is a printed circuit board that is received in the receiving slot 12 .

The vibration motor 30 can be accommodated in the clamping groove 14 . The vibration motor 30 includes a motor body 32 and an eccentric wheel 34 connected to the motor body 32 via a rotating shaft. One side of the motor body 32 is formed with two elastic pieces 322 for electrically connecting the vibration motor 30 to the secondary circuit board 40.

The secondary circuit board 40 is a flexible circuit board that is bendably supported by the partition wall 16 and has two electrical connection points (not shown) formed at one end thereof, and the two electrical connection points are used for The two elastic pieces 322 of the vibration motor 30 are connected to electrically connect the secondary circuit board 40 and the vibration motor 30 housed in the clamping groove 14. The other end of the secondary circuit board 40 is connected to the main circuit board 20 to turn on the main circuit board 20 and the vibration motor 30.

The upper casing 50 is configured to cooperate with the lower casing 10 such that the main circuit board 20, the vibration motor 30, and the secondary circuit board 40 are assembled between the upper casing 50 and the lower casing 10.

When the vibration structure 100 of the electronic device is assembled, the main circuit board 20 is first placed in the accommodating groove 12, and then one end of the secondary circuit board 40 is connected to the main circuit board 20, and the other end is connected. Bending on the side wall of the clamping groove 14 on the side of the partition wall 16, then placing the vibration motor 30 in the clamping groove 14, and the elastic piece 322 of the vibration motor 30 abuts against the secondary circuit board 40 Two electrical connection points.

Finally, the upper casing 50 and the lower casing 10 are assembled to securely assemble the main circuit board 20, the vibration motor 30, and the secondary circuit board 40.

In this way, the vibration motor 30 is disposed on one side of the main circuit board 20, and is electrically connected to the vibration motor 30 through the secondary circuit board 40, thereby reducing the thickness of the electronic device and greatly saving the main circuit board 20 board. The layout of the surface.

In summary, the creation meets the requirements of the invention patent, and the patent application is filed according to law. However, the above-mentioned ones are only preferred embodiments of the present invention.
