Problems solved by technology

[0005] However, the vibration direction of the vibrator of the above vibration motor is vertical, that is, perpendicular to the installation plane, because it is perpendicular to the installation plane, so it is necessary to provide a large vertical height to facilitate the vibrator to move up and down, so that the height of the entire motor increase, and is not conducive to the development of thin

Embodiment Construction

[0024] The content of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The invention is a flat linear vibrating motor, which is mainly used in consumer electronic products such as mobile phones and handheld game machines.

[0026] Please refer to Figure 1 to Figure 3 , the flat linear vibration motor 10 includes an upper cover 11 , a base 12 assembled with the upper cover 11 to form an accommodation space, an annular coil 13 , several elastic supports 14 , counterweights 15 and permanent magnets 16 .

[0027] The base 12 is provided with a plurality of side walls 121 and a bottom wall 122 vertically connected to the side walls 121. The coil 13 is positioned on the bottom wall 122 and its coil leads (not shown) are welded to the conductive sheet 123 positioned on the bottom wall 122. , in order to obtain alternating current from the outside, the elastic support 14 is positioned on the base 12, preferably on the si...

Abstract

A flat linear oscillation motor comprises an upper cover, a base matched with the upper cover to form a holding space, a coil which contained in the holding space and positioned on the base, an elastic supporting piece connected with the base and a permanent-magnet that is hung in the holding space by the elastic supporting piece; wherein, the base is provided with a plurality of side walls and a bottom wall being vertical to the side walls, the coil is arranged on the bottom wall and positioned in the center under the permanent-magnet, a gap is arranged between the coil and the permanent-magnet, the magnetic pole of the permanent-magnet just faces the coil, and the polarization direction of the magnetic pole of the permanent-magnet facing the coil is opposite, the elastic supporting piece is provided with a fixing part connected with the base, an elastic arm that extends out from and faces the fixing part and has the elastic deformation direction to be parallel to the bottom wall of the base, and a jointing part that extends out from the elastic arm and is connected with the permanent-magnet to lead the permanent-magnet to move along the direction being parallel to the bottom wall.

Description

【Technical field】 [0001] The invention relates to a vibration motor, in particular to a flat linear vibration motor used in portable consumer electronic products. 【Background technique】 [0002] Portable consumer electronic products, such as mobile phones, handheld game consoles, navigation devices, or handheld multimedia entertainment equipment, generally use vibration motors for system feedback, such as mobile phone call notifications, game console vibration feedback, etc., which are used There are several types of motors, such as cylindrical iron core motors, hollow cup motors and flat motors. [0003] With the development of consumer electronic products in the direction of thinner and lighter, various internal components also need to adapt to the trend of thinner and lighter. Motors are no exception. [0004] Linear vibration motor refers to the reciprocating motion in which the vibration direction of the vibrator is a straight line. Because of its stable vibration and...
