The magnetic circuit unit 120 includes a plate 121 coupled to the bottom surface of the support plate 115, a magnet 123 coupled to the bottom surface of the plate 121, and a support plate 125a and a base plate coupled to the bottom surface of the magnet 123. It includes a yoke 125 having a pole 125b protruding from the center of the 125a. Communication holes 121a and 123a are formed at the centers of the plate 121 and the magnet 123 so as to face the through holes 116, and the poles 125b are the communication holes 121a and 123a and the through holes 116, respectively. It is located inside of. At this time, a gap is formed between the inner circumferential surface of the communication holes 121a and 123a and the outer circumferential surface of the pole 125a.

The vibrator 130 is formed in a track shape and the outer peripheral surface side of the damper 131 is adhesively bonded to the support plate 115, the lower side is located in the gap of the magnetic circuit unit 120, the central side is the inner peripheral surface of the damper 131 The upper side is coupled to the upper end of the voice coil 133 and the outer peripheral surface is located on the upper side of the damper 131 and the upper edge of the support frame 111 and the upper side of the voice coil 133 is coupled to the inner peripheral surface It has a diaphragm 135.

Thus, when external power is supplied to the voice coil 133, the voice coil 133 vibrates in the vertical direction of the frame 110 by the action of the voice coil 133 and the magnetic circuit unit 120, the diaphragm 135 Vibrate. Then, the diaphragm 135 vibrates in the vertical direction of the frame 110 to reproduce sound.

The damper 131 prevents the voice coil 133 from flowing from side to side to prevent the vibration plate 135 from flowing from side to side, and simultaneously supports the voice coil 133 and the vibration plate 135 from vibrating smoothly. .

The slim speaker according to the present exemplary embodiment supports the voice coil 133 using a relatively large damper 131 so that the vibrator 130 may vibrate more smoothly.
