Problems solved by technology

When this structure is adopted, the two sides of the counterweight are heavy and the middle structure is relatively weak. During the production process, it is easy to break in the middle position, which makes it difficult to form the counterweight, and the finished product of the counterweight is not rigid enough, so it falls poor reliability

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Figure 1-3 A vibration motor 100 in one embodiment of the present invention is shown. like Figure 1-3 As shown, the vibrating motor 100 generally includes a casing 10 with a receiving space (not labeled), and a fixing component 20 , a vibrating component 30 and an elastic connecting member 40 accommodated in the casing 10 . Wherein, the housing 10 includes a housing 11 and a cover plate 12 covering the housing 11 to cooperate with the housing 11 to form a receiving space. The fixing assembly 20 is fixed on the cover plate 12 . The vibrating assembly 30 is suspended in the accommodating space through the elastic connecting piece 40, and is perpendicular to the length direction of the cover plate 12 (see Figure 2-3 In the Y direction) reciprocating vibration.

[0027] Specific as Figure 2-3 As shown, in this embodiment, the fixing assembl...

Abstract

The invention provides a vibration motor comprising a shell, a fixing component and a vibration component which are accommodated in the shell, and an elastic connecting member which suspends the vibration component in the shell. The fixing component comprises a coil which is fixed in the shell. The vibration component comprises a counterweight block and a magnetic steel component which is fixed on the counterweight block. The counterweight block comprises a main body part, a first side part and a second side part which are respectively arranged at the two sides of the main body part, and a groove which is formed by the main body part, the first side part and the second side part through enclosing and used for arranging the magnetic steel component. The main body part is also provided with a reinforcing rib which is arranged in the groove. The vibration motor is high in rigidity, high in falling reliability and easy to form.

Description

【Technical field】 [0001] The invention relates to vibration motor technology, in particular, to a vibration motor suitable for portable consumer electronic products. 【Background technique】 [0002] With the development of electronic technology, portable consumer electronic products are becoming more and more popular, such as mobile phones, handheld game consoles, navigation devices or handheld multimedia entertainment equipment, etc. These electronic products generally use vibration motors for system feedback. Such as mobile phone call prompts, information prompts, navigation prompts, vibration feedback of game consoles, etc. [0003] The vibrating motor of the related art has a vibrating assembly, and the vibrating assembly includes a counterweight with two sides connected to each other by a column. When this structure is adopted, the two sides of the counterweight are heavy and the middle structure is relatively weak. During the production process, it is easy to break at ...
