DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ti moving body
of a rigid dynamic telephone speaker in which a voice coil is provided on a bobbin and a
diaphragm is fixed to the bobbin. 1174.9〃ノフ′。 In conventional loudspeakers, firing of
the hobbin and diaphragm due to overheating of the voice coil and its lead wire has become a
problem, and various measures have been considered. For example, a diaphragm, a bobbin, etc.
were formed of a material having a self-retarding property, or a paper for fixing a voice coil on a
bobbin was formed of a fiberglass of a glass wool releasability, a paper sheet In the case of a
small book, the flame retardant material itself is not suitable as a diaphragm in physical
properties such as Young's modulus, internal loss, etc., or the bobbin mass is increased. It was
difficult to securely fix thin lead wires on a bobbin in a round shape made of hard material. The
present invention is made in view of the above-mentioned drawbacks, and it is also possible to fix
the lead wire on the bobbin with thin fire-retardant 1 # paper with K 11771; 1 light emperor Jl!
It is an object of the present invention to provide a vibrator of a speaker in which the fixing of
the lead wire and the fixing of the diaphragm are performed simultaneously and easily by the
adhesive contained therein, and an increase in the extra mass is prevented. Hereinafter, an
embodiment of the present invention will be described with reference to the drawings. The
electrodynamic bib's vibrator comprises a bopin 2 around which a voice coil 1 is wound, and an
& moving plate 3 bonded to the bobbin 2. Conventionally, the rounding sleeve [4] from which the
voice coil 1 is derived is wound on the bobbin 2 and fixed to the round band sheet SK, but in the
embodiment of the present invention, the band sheet i is flame retardant as shown in FIG. It is
desirable to use a quantity of an aromatic, non-woven fabric composed of a viscous polyamide
fiber and having a web-like structure, preferably 201-5 ° υ 讐 tt7s). The strip 5 is impregnated
with a polyamide or phenolic adhesive 6 which is compatible with the strip 5 and then wound
while holding the lead 4 on the bobbin 2. Further, the neck portion 3 & of the diaphragm 3 is
further superimposed on the band paper 5, and the band paper 5 itself, the fine lead 4 and the
diaphragm 3 are all firmly fixed on the hobin 2 by imaging of the adhesive 6. Ru. The adhesive 6
in this case may be impregnated in the band paper 5 in advance and wound around the bobbin 2
as described above, but may be coated and impregnated while the lead wire 4 is held. According
to this embodiment, the aromatic polyamide imperial cap 5 is self-extinguishing, non-melting,
carbonizes at about 426 ° C., and the voice coil 1 is overinput 9, lead 4, 117 C: )) 114 does not
burn even if it becomes red, and since the bonding between the bobbin and the diaphragm 3 is
performed via the aromatic polyamide strip 5 impregnated with the adhesive 6 inside, ordinary
paper It is more stable than the case where our band paper is used.
Furthermore, if the adhesive 6 impregnated in the paper band 5 is not brought into contact with
the lead edge 4, ignition from the adhesive also occurs more easily. The present invention is as
described above, since the lead wire is fixed on the bobbin by the band paper of &&, the spread
from the lead edge can be prevented, and since the band paper is non-woven, it is flexible. The
lead edge can be closely attached on the bobbin so that it can be fixed securely. Also, since the
paper is impregnated with an adhesive, the non-woven fabric itself may be thinned, and the
external pole accuracy of the voice coil can be enhanced and made into an amount of 1. The Kti
moving plate can also be fixed on this sheet by means of this adhesive 180)), and the
manufacturing process can be simplified. Brief Description of Section 4 Ji & 1 is a drawing of the
