Embodiment Construction

[0022] Below, use figure 1 , figure 2 and image 3 To represent the best embodiment of the present invention.

[0023] figure 1 Represents the overall perspective view of the multifunctional vibration actuator used in this embodiment, figure 2 express figure 1 A side sectional view of the A-A' section, image 3 represents an exploded perspective view, and Figure 4 express figure 2 An enlarged view of the periphery of the protrusion. in addition, figure 2 A part of the background line is omitted in .

[0024] From figure 1 , figure 2 and Figure 4 It can be seen that the multifunctional vibration actuator used in this embodiment has a structure in which the protrusion C of the suspension 5 and the case 4 protrude from the cover 11 . Therefore, when a load in the thickness direction is applied, the suspension 5 receives the load, and the protruding portion C can prevent the case 4 from sinking into the cover 11 due to deflection when an uneven load is applied....

Abstract

Provided is a multifunctional vibration actuator, which enables load resistance to be improved while preserving improvements to impact resistance and space-saving performance afforded by a thinner profile. An outer periphery section of a suspension is constructed so as to protrude from the housing, making it possible to improve load resistance against external pressure while retaining a thin profile. Configuring the suspension to be integrated with the housing additional yields the effect of reducing the quantity of components and the corresponding number of production requirements, and increasing durability as afforded by the integrated structure.

Description

technical field [0001] The present invention relates to a multi-functional vibration actuator, comprising a magnetic circuit part with a magnet and a vibrating film with a voice coil, the magnetic circuit part is supported in a casing by a suspension, and the above-mentioned vibration circuit is installed at the end of the casing The membrane has a function of generating somatosensory vibration based on the vibration of the magnetic circuit unit by input to the voice coil and performing sound reproduction based on the vibration of the vibrating membrane. Background technique [0002] Currently, mobile communication devices typified by mobile phones are provided with a sound reproduction function and a somatosensory vibration generation function for notifying a user of an incoming call by reproducing incoming tone or somatosensory vibration. Furthermore, in order to add these two functions with a single component, a multifunctional vibration actuator that shares a magnetic ci...
