DESCRIPTION JPS61137498
[0001]
FIELD OF THE INVENTION This invention relates to speakers. Prior Art A conventional
loudspeaker will be described with reference to FIG. In FIG. 3, (1) is a voice coil, (2) is a steel foil
thread wire of the voice coil (1), and (3) is a lower plate. (4) is a magnet, (5) is a top plate, (6) is a
damper, (7) is a frame, (8) is a cone, and (9) is a terminal. Thus, the voice coil (1) to which the
steel foil thread wire (2) is attached is very excellent in terms of solderability and the like, and its
application to various speakers is being developed. However, in the speaker using the
conventional steel foil yarn (2), the steel foil yarn (2) oscillates in space, so that the cone (8) of
the peripheral portion, There is a problem that it hits the damper (6), the frame (), etc. and
generates an abnormal sound. In addition, although life breakage occurs due to the life breakage
due to excessive pulling of the steel foil yarn wire (2) and the forming shape of the steel foil yarn
wire (2), there is a problem that forming of forming jig is difficult. An object of the present
invention is to provide a speaker which solves the above-mentioned problem. Means for Solving
the Problem In order to solve the above-mentioned problem, a speaker according to the present
invention is a damper in which a steel foil film is fixed which is connected to a terminal attached
to a wire μ frame of a voice coil. In the above configuration, the steel foil film is used instead of
the steel foil wire, and since the steel foil film is fixed on the damper instead of being oscillated in
space, as a wire from the voice coil to the terminal The steel foil film can prevent abnormal noise
generated by hitting the peripheral components due to the vibration amplitude at the time of the
speaker operation, and can prevent breakage in life due to the length of the steel foil film and the
badness of forming . Embodiment An embodiment of the present invention will be described
below with reference to FIGS. 1 and 2. FIG. FIG. 1 is a cross-sectional view of the right half of the
speaker according to an embodiment of the present invention. The same components as those
shown in FIG. 1st ri! In (I), (io) is a steel foil film, and this steel foil film (10) is a biscolloid (acrylic
polymer) containing a flexible silicon adhesive or plasticizer on a damper (6) It is fixed by etc.

Also, as shown in FIG. 2, this steel foil film (10) is a film (11) in which a steel foil (12) is
embedded, and the steel foil (12) needs to be changed depending on the input of the speaker ,
About 0.01 to 0.2 (ml).
Further, the film (11) is preferably a polyester type that can be folded into one elasticity, and the
thickness needs to be 0.05 to 0.5 [■]. Thus, instead of using steel foil wire (2), use steel foil film
(10), and instead of vibrating steel foil film (10) in space, use flexible material on damper (6) The
steel foil film (10) as a relay wire from the wire of the voice coil (1) to the terminal (9) is an
abnormal sound generated when it hits peripheral components by vibration and amplitude at the
time of speaker operation. While being able to prevent, it is possible to prevent breakage in life
due to the wrinkles of the steel foil film (10) and the badness of forming. Effect of the Invention
As described above, according to the present invention, it is possible to completely prevent
abnormal sound at the time of speaker operation. In addition, the steel foil film is assisted by the
elasticity of the film, and the steel foil does not cut even with large amplitude. The speaker life
can be extended, and unlike steel foil wire, one side is covered with a film, so that the risk of
short circuit with a frame or the like can be prevented.
