DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the construction
of the tamper which mounts the speaker. The structure of the tamper is as shown in FIG. 1 (this,
between the center outer edge of the imaging plate 13 and the frame 11 (an adhesive having a
solid solid key, 5-12). One-character correction etc. (Stabilized by this, tamper 12 supports voice
1 o ? q ? ? 2 coil 14 and vibration & 13 at a predetermined center position, and needs a
function to facilitate vibration deviation of the entrance diaphragm 13 Do. However, (the tamper
12 is concentric 1,-town-4) in order to facilitate the vibration & 13 vibration deviation, the life is
given in the form of a j circle. Although this wedge functions to correct the shape of the tamper
and support the voice coil 14 and the diaphragm 13 at a predetermined center position, the
function to support the center position is still insufficient. A cloth base material used for the
damper is impregnated with a thermosetting resin liquid, for example, phenol resin liquid, and
the mold is concentrically formed with a mold made of 17iTjT metal, and the shape retention is
imparted by the mold. Means are used to double the action of supporting the position and to
provide a tamper resistant tamper. Such tamper 12 radially radiates the displacement vibration
generated by the diaphragm 13i (this attachment is transmitted to the frame 11 and reflected in
the city, causing a reflected wave from the removing portion toward the central portion). It is a
harmful vibration that excites the plate 13. In this case (this vibration to transfer the crowbar 12
shell is the material and shape of the crowbar 12, especially nourishment! Revised d part (it is
absorbed but it is still satisfactory and there is no -2-'3). The present invention is made to
improve such a drawback of the conventionally known speaker damper mounting structure, and
the damper mounting structure in the speaker of the present invention is shown in FIG. As shown
in the embodiment, an outer edge vertical portion 22a of the tamper 22 is provided, and between
the vertical portion 22a and the frame 21 (a ring 26 of rectangular rectangular cross section
made of a foam that absorbs vibration such as urethane foam is parallel The glued tapper tongue
is a structured loudspeaker. According to this configuration, the deflection vibration generated in
the diaphragm 23 is propagated in the radial direction of the tamper 22 to reach the annular
ring 26 + two, and the annular ring 26 (this generates a shear force in a direction substantially
perpendicular to it and is deformed. Such shear deformation (therefore, stress of deflection
vibration can be stored in the ring 26 to measure absorption of vibration. The ring 26 may be a
foam of a structure that absorbs vibration, and this foam can increase the shear deformation as
the rigidity is smaller than that of the Tampa 22 and has the effect of absorbing the stress of
deflection vibration. It will be great.
In this way (this, the ring 26i fully absorbs the offset vibrational stress of the Dan 4 bar 22 so
that the generation of harmful vibrational stress due to the reflected wave is extremely reduced,
and a speaker that reproduces good sound. You can get
