Problems solved by technology

[0007] Here, it can be seen that significant surface tension occurs inside the short connection portion 44 arranged on the short side of the suspension 40, and therefore, cracks may easily occur in the conductive pattern 50 formed on the surface of the suspension 40.

Embodiment Construction

[0030] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0031] Figure 5 is a view showing the structure of the lead-in wire of the voice coil provided in the high-power microspeaker according to the first embodiment of the present invention. The voice coil 100 provided in the high power microspeaker according to the first embodiment of the present invention is formed in a rectangular shape like a conventional rectangular coil 10 . However, there is a difference between the voice coil 100 provided in the high-power microspeaker of the present invention and the voice coil 10 of the prior art in the drawing directions of the lead wires 120 and 140 . The lead wires 120 and 140 of the voice coil 100 are not arranged side by side on the same side of the rectangular shape, but drawn out from opposite diagonal sides. Preferably, the leads 120 and 140 are drawn from the ends of the two longer sides...

Abstract

The invention relates to a suspension structure for a high-power micro speaker, in particular to the shape of a suspension. By the shape of the suspension, the lightweight and high reliability of the suspension and a conductive pattern for applying an electrical signal are ensured. The invention provides a suspension for the high-power micro speaker. The suspension comprises a peripheral part, a center part and connecting parts, is provided with the conductive pattern, and is rectangular, wherein welding parts for the welding or fusion of incoming lines of a voice coil are formed on the long connecting parts which are arranged on long edges.

Description

technical field [0001] The present invention relates to a suspension structure for a high-power microspeaker, and more particularly, to a shape of a suspension that ensures light weight of the suspension as well as high reliability and conductive patterns for applying electric signals. Background technique [0002] The sound reproduction technology of mobile multimedia has been improved along with the development of mobile communication technology, therefore, micro speakers are required to have high performance, high sound quality and high power. [0003] In most cases, a conventional microspeaker does not use a specific suspension to ensure the lightness of the diaphragm, and connects the leads of the voice coil to the diaphragm via bonding to apply an external electric signal to the voice coil. Therefore, due to the lack of suspension, there is often unbalanced vibration, and the lead wires of the coil often fail due to tension under high power, which makes it difficult fo...
