发明名称 MICRO SPEAKER
摘要 PROBLEM TO BE SOLVED: To provide a micro speaker that can enhance the assembly and the performance of the product by eliminating restrictions in a conventional micro speaker such that a winding end of a voice coil of the micro speaker is led out from an adhered section of the voice coil to a diaphragm or adhered to a lower face of the diaphragm. SOLUTION: A recessed part 1d is formed around a part at which the winding end 9 is led out from the voice coil 5 by providing a notch on a cylindrical part of a yoke 2 and a sink on a bottom of an inner face of a case 1 in contact with the notch. Passing the winding end through the recessed part to lead the winding end to the outside of the case eliminates the need for placing the end along a lower side of the diaphragm because of provision of a space margin, and the winding end may be extracted from a free end of the voice coil. Thus, it is possible to make the voice coil close to the diaphragm while being fitted to a winding axis and to join the voice coil so as to facilitate automated assembling thereby preventing the winding end from contacting the surrounding components because of a narrow space.
