On the other hand, for PDAs, notebook computers, and IMT2000 communication terminals, etc., the user listens to the reproduced sound at a distance from the device. Such portable devices cater to the miniaturization of the overall size and weight and reduce their size, so the miniature speakers used also need to be continuously reduced in size. Moreover, with the development of wireless network technology and the construction of IMT2000, these micro-plastic speakers need to be easy to accept music files, and like the theater speakers, need high-input/high-output, and high-pitched to high-frequency reproduction. 201016040 The first figure is an exploded perspective view showing an example of a technical microspeaker, and the second figure is a cross-sectional view showing the vibration plate of the first figure. The structure of the conventional microspeaker will be described with reference to the first and second figures as follows. The conventional microspeaker 100 includes a yoke 20 having a groove 22 formed at the center, a magnet 3 插入 inserted at a certain interval from the inner wall of the groove 22, a plate 32 mounted on the magnet, and a main body connected to the outside of the yoke 20 to form a main body Rack 10; vibrating plate 5〇 supported by the inner end of the frame; voice coil 40·' and protective plate 7G attached to the lower surface of the vibrating plate and sandwiched between the magnetic wheel 20 and the magnet 30 to vibrate up and down It covers the open upper portion at the upper end of the frame, and is formed with at least one sound-receiving hole 72. Further, a terminal for supplying an external signal to the voice coil 40 is formed on one side of the holder 1 (). In the microspeaker of such a configuration, the voice coil 40 that receives the external signal interacts with the plate 32 that is magnetized by the magnet 30, and the like, thereby vibrating up and down 'because the vibration' is connected to the vibrating plate 5 below the voice coil.

The polymer compound of the mono-(10) is pressure-bonded to the remainder (four), thereby forming the same: - a polymer compound of the vibrating plate. That is, the vibrating plate 5 is used. : Medium shape' thus reluctant structural strength. However, the problem of large distortion of the sound is caused by the single-component vibrating plate 2010ο 201016040. In order to solve such a problem, a method of fabricating the vibrating plate 50 according to the steps shown in the third and fourth figures is proposed: a light-weight and high-strength rigid member 1〇2 is laminated on the central crucible 111b of the polymer compound film lu.

Further, after the rigid member 102 is bonded to the upper diaphragm 101 (S54) and adhered to the lower diaphragm 103 (S55), the rigid member 102 to which the diaphragms 1〇1, 1〇3 201016040 are bonded is punched. Cut the polymer contact member (10) thus produced. The rigid member 1〇2 of 101, 103 is adhered, 111 and bonded to the diaphragm to complete the vibration plate 110. - After 'drying (S57), However, as shown in the fourth figure, the problem of chemical resistance and moisture resistance of the vibration plate 110 due to the side surface of the rigid member 102 is not satisfactory. As described in the fifth figure, Since the production, the lamination and bonding of rigid members, and the like, the process of the polymer compound film is complicated, the manufacturing process is complicated.
