wherein said lead wire (¶[0026]: terminal lead 110) remains at a single surface of said membrane (FIG. 1: the surface of the coupler 114 which is a part of the diaphragm 108) without perforating said membrane (FIG. 1: the terminal lead 110 remains at the surface of the coupler 114 and does not perforate the diaphragm 108); however Little is silent to a lead wire configured to be directly guided to said voice coil, and wherein the lead wire is connected to the voice coil at a location of a voice coil former.
Zheng teaches a loudspeaker (FIG. 1: loudspeaker 1) comprising a wire (wire 91, fig. 3) connected to a voice coil (¶[0048]: voice coil 33) at a location of a voice coil former (¶[0049]: a conductive sheet 34 is fixedly disposed on the outer bobbin 31, and alternatively, the conductive sheet 34 is a tin foil, and the tin foil is welded to the outer bobbin 31. The coil 33 is electrically connected to the conductive sheet 34, and circuit leads 91 are provided on the damper 9, the conductive sheet 34 is electrically connected to the circuit leads 91, and the circuit leads 91 are configured to be electrically connected to external devices).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to utilize the teachings of Zheng into the teachings of Little in order to provide an ultra-thin speaker, Ultra-thin speakers are required for ultra-thin electronic products such as ultra-thin liquid crystal displays.
Regarding claim 18, Little in view of Zheng teaches the loudspeaker as in claim 17.
Little further teaches wherein said holders (¶[0028]: coupler 114) are disposed at said back surface of said membrane (¶¶[0031], [0037]: the diaphragm 108 may be fabricated with coupler 114 integrally formed on its lower surface).
