Embodiment Construction

[0025] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

[0026] image 3 is an exploded perspective view showing a microspeaker having a terminal structure according to an embodiment of the present invention. In the microspeaker having the terminal structure according to one embodiment of the present invention, a magnetic circuit is provided in the frame 100, and a vibration unit is provided on the frame 100, which vibrates due to mutual electromagnetic force with the magnetic circuit and produce sound. A protector 600 positioned on the vibration unit is coupled to the frame 100 to protect the magnetic circuit and the vibration unit. In addition, a terminal 700 is coupled to the frame 100, the terminal 700 being in contact with an external power source to transmit an electric signal to the micro speaker.

Abstract

The present invention relates to a terminal structure of the micro-speaker. More specifically, relates to a terminal structure of the micro-speaker. The terminal is connected to the frame structure and is in contact with the external power supply to deliver an electrical signal to a vibration unit in a frame.

Description

technical field [0001] The invention relates to a terminal structure of a micro speaker. More particularly, the present invention relates to a terminal structure of a microspeaker coupled to a frame and in contact with an external power source to transmit an electric signal to a vibration unit in the frame. Background technique [0002] figure 1 is an exploded perspective view showing a conventional microspeaker, and figure 2 is a cross-sectional view of a conventional microspeaker. In a conventional microspeaker, the yoke 21, the inner ring magnet 22, the outer ring magnet 23, the inner ring top plate 24 and the outer ring top plate 25 are arranged in the frame 10, and the voice coil 30 is arranged on the inner ring magnet 22 and the outer ring magnet 23. and vibrate vertically when power is applied to the voice coil 30 . The voice coil 30 is installed on the bottom surface of the hanger 50 , and the side diaphragm 41 and the center diaphragm 42 are disposed on the top...
