Abstract

The present invention relates to a method for coupling a frame and a yoke, in which an assembly process is improved, and to a speaker using same. The speaker of the present invention comprises: a vibration plate which generates sound through vibration; a voice coil attached to the vibration plate to vibrate the vibration plate when a current is applied thereto; a frame, including an upper housing for supporting the vibration plate and a lower housing with a space for accommodating a yoke; the yoke, which is hooked to the space of the lower housing of the frame; a magnet attached to the center of the yoke; and a plate stacked on the magnet. The yoke is inserted in the space of the lower housing of the frame in such a manner that the hook that protrudes from the end of the side wall of the yoke gets caught by the edge of the lower housing of the frame or by the protrusion formed at the lower housing.

Description

Technical field [0001] The present invention relates to a speaker, and in particular, to a method of combining a frame and a yoke that can reduce manufacturing costs by improving the assembly process, and a speaker using the method. Background technique [0002] Generally, a speaker is an audio device in which the voice coil attached to the diaphragm is located in the gap (Gap) between the plate and the yoke in a magnetic circuit composed of a plate, a magnet and a yoke, and an electric signal flows in the voice coil At this time, the vibrating plate vibrates to generate density waves in the air, thereby generating sound waves. [0003] In a micro speaker used in a portable electronic product such as a mobile phone, the U-shaped yoke forming the magnetic circuit is supported by being combined with the inner space of the frame, and the vibration plate is also supported by the frame. At this time, in the microspeaker, the existing method of coupling the frame and the speaker is as f...
