Embodiment Construction

[0060] Hereinafter, example embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0061] figure 1 is a perspective view of a speaker 1 according to an example embodiment. figure 2 is along figure 1 A cross-sectional view of the loudspeaker 1 taken by the line A-A'. image 3 is an exploded perspective view of the speaker 1 according to an example embodiment.

[0062] like Figures 1 to 3 As shown, the speaker 1 includes a frame 10 formed in a hollow shape, a magnetic circuit unit 20 arranged in the frame 10 , and a vibration unit 30 arranged to vibrate due to the magnetic circuit unit 20 .

[0063] The frame 10 constitutes the appearance of the loudspeaker 1 and has a rectangular shape in plan view, wherein the appearance of the frame 10 has a major axis and a minor axis. An elliptical through hole 11 is formed in the center of the frame 10, and a plurality of grooves 13 are formed in a lower portion of the frame ...

Abstract

A speaker includes: a diaphragm having a major and a minor axis; and a damper configured to adjust vibration of the diaphragm and including a first and second metal plates, wherein the damper further includes first and second deformation prevention members disposed on rear surfaces of the first and second metal plates, respectively, and wherein first and second deformation prevention members protrude towards the rear of the speaker and extend along a major-axis direction of the diaphragm, and the first and second deformation members are configured to prevent deformation of diaphragm caused by a load perpendicular to the plane of the diaphragm.

Description

technical field [0001] An apparatus according to example embodiments relates to a slim type speaker, and more particularly, to a speaker capable of reinforcing strength. Background technique [0002] The speaker is a sound output device in which the electrical signal output from the audio amplifier is converted into the vibration of the vibration unit, which generates density waves in the air, thereby generating sound waves. According to the working principle of the speaker, the speaker is classified into different types such as magnetic speaker, dynamic speaker, electrostatic speaker, piezoelectric speaker and ceramic speaker. [0003] In the prior art, a loudspeaker includes: a magnetic circuit unit including a magnet for generating magnetic flux, a yoke portion for providing a path for the magnetic flux; and a bobbin on which a voice coil is wound; a frame (frame) and a vibrometer including a diaphragm vibrating according to the movement of the bobbin, a damper for adjus...
