Viscoelastic material
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement
of the frame portion of a loudspeaker. In general, the frame of the speaker supports the
transmission WjJ board so that it can vibrate, and the installation of the steering wheel of the
speaker also comes, and if the speaker board of the speaker is manufactured, the frame may
cause parasitic vibration . Therefore, the object of the present invention is to leave the
mechanical strength of the frame as it is and to prevent its parasitic vibration by other means.
That is, as shown in the figure, the speaker 11 according to the present invention has a structure
in which the viscoelastic material 14) is attached to the frame 131 supporting the diaphragm
12+ in a vibrating manner. Here, the visco-elastic material (4 is made of a mixture of rubber,
sponge, rubberized asphalt 7) and these mixtures. Then, the visco-elastic material 14), the first
speaker +1) is partially exposed on the surface and the back of the frame (the entire surface of
the surface 31 and the frame 13 in v4-N in FIG. 2). In the embodiment of 61, the legs of the
perforated frame 13) are attached in such a way as to surround them. In any case, in the sticking
position! A node of jA motion is formed as a middle part t. (2) Nona In the present invention,
since the viscoelastic material does not form a node in the frame even if the vibration is
performed by the vibration plate and the vibration is transmitted to the frame, the frame is
moved. Can be prevented. Therefore, the present invention is effective in improving the sound of
Nakajima range. When the present invention is used, even if the material of the frame is not
converted to Kft, there is also the possibility that it can be configured as it is with cast-iron, iron,
synthetic llk etc.
