[Detailed Description of the Invention] The present invention has 314 vibration models on its
entire surface. It is an @ room type speaker Q, and it is detailed in the history.) This is a Yori
made of soft magnetic material such as iron. In the ring-shaped magnet, its magnetic poles
alternate, and the whiteness is inverted to form one concentric circle (pole open face G of the
magnetic circuit disposed separately, outside the air gap; /// "" "" "" "2 The present invention
relates to an electrodynamic speaker in which a vibrating membrane in which a voice coil is
formed by printing a conductor such as aluminum in the form of a vortex and having an
electrical insulating property exclusively for polyester and having a high tension. In the
electrodynamic speaker of this structure, one end 12 of the input end of the voice coil 5 is an
outer peripheral portion of the diaphragm 4 (one end 9 is a central portion of the diaphragm 4 as
shown in FIG. 1). The lead wire 6 not only cuts out the front of the diaphragm 4 to disturb signal
pressure but also disturbs the reproduced sound pressure, as well as shooting in the central area
of the lively LIJI Osaka 4 in a row, in a row or in a row 6 There is a drawback that the motion is
transmitted and a vibration mode like a string is generated to disturb the vibration characteristics
of the moving plate. In addition, there is a defect that the noise of the lead wire changes in a
rough manner depending on the quality, shape, and history of the lead wire and provides an
electrodynamic speaker of constant quality. The present invention has been made to solve the
problem of acupuncture and its aim is to provide a moving-center-type speaker with stable
characteristics without disturbing the vibration characteristics of the vibrating membrane. 3 and
4 as shown in FIG. 3 and FIG. 4, the vibrating film is coiled of aluminum on the back surface of
the polyester film 4 '(the center of the voice coil 5' made of this material). A wire is formed
between the aluminum foil 7 and one end 12 of the outer periphery of the voice coil 5 'by
connecting the one end 9 of the portion and the aluminum layer 7' laminated on the front
surface of the polyester film 4 '. It is a dynamic electrodynamic speaker In the case of the Eshaped speaker of this structure, since the polyester film 4 'and the aluminum layer 7' are
integrally picked up in proportion to the signal current, the isodynamic characteristic is not
disturbed. become. In addition, a vibrating membrane in which an aluminum mini-lam layer 7 'is
laminated on a polyester film 4' has an aluminum layer compared to the polyester film 4 '.
Because the ratio of 7 'Young's modulus and inter-filament ratio is large, there are many points
such as Lii 4 I that are wide in the adjustment range, so it can be a destructive vibrating film and
practical improvement such as improvement of electroacoustic conversion efficiency It is an
excellent device that has a positive effect.
