DESCRIPTION JPS63151297
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
diaphragm of a full drive speaker and a method of manufacturing the same. (Prior art and its
problems) A flat plate substrate constituting a diaphragm of a full drive speaker is a diaphragm
substrate which is practically sufficient because of its lightweight physical properties and high
rigidity. The present condition is that you can not obtain (Means for Solving the Problems) The
present invention has been proposed to solve the above problems, and it is a lightweight and
highly elastic vibration applying an electrolytic deposition method (hereinafter referred to as an
electrodeposition method). It aims to provide a board. That is, in order to achieve the above
object, the present invention is a vibration plate of a full drive speaker, in which the diaphragm
base is formed of a ceramic and the conductor is formed of aluminum. A plate is a summary, and
one side of an aluminum flat plate is masked with a resist agent, a ceramic layer is formed on the
other side of the aluminum flat plate by electrolytic deposition, the resist is removed, and then
exposed aluminum Method of manufacturing a diaphragm of a full drive speaker characterized in
that a conductor pattern is masked on the surface using a photoresist agent, and an aluminum
flat plate is immersed in a solution of acid or alkali to form an aluminum conductor in the
ceramic layer. Is the gist. (Operation) The present invention forms a ceramic layer on one side of
an aluminum plate by electrodeposition, applies a mask of a conductor pattern to the other side
of the aluminum plate, dissolves and removes the aluminum plate, and forms a conductor pattern
on the ceramic layer. A lightweight and highly elastic diaphragm can be obtained by the method
of manufacturing the diaphragm in which (Example) As an electrolytic bath composition, a resist
agent is coated on one side of an aluminum plate in an aqueous solution of potassium silicate
200 a / l, the aluminum plate is used as an anode, and an iron plate is used as a cathode. Direct
current flows continuously while holding at / dm2. The anodic current density was applied for
20 minutes to 1 A / c 1 m 2 to form a ceramic layer of silicon oxide having a thickness of 30 to

40 μm on the aluminum plate. The thickness of the ceramic layer is a thickness desired
according to the size of the diaphragm and other conditions. After the ceramic layer is formed,
the resist agent is removed, and the exposed aluminum surface is masked with a photoresist
layer according to a desired conductor pattern. Next, the aluminum flat plate is immersed in an
acid or alkali solution of aluminum to dissolve and remove aluminum other than the mask
portion.
Through the above-described steps, a diaphragm of a full drive speaker in which a conductor
pattern made of an aluminum conductor is formed on the ceramic layer is obtained. Next, the
diaphragm of the present invention will be described. The figure is a cross-sectional view of a full
drive loudspeaker to which the diaphragm obtained by the manufacturing method of the present
invention is applied. In the figure, 1 is a diaphragm substrate of ceramics formed by the
electrodeposition method, 2 is a conductor of aluminum formed on the surface of the diaphragm
substrate, 3 is a magnet, 4 is a magnetic plate, and is a conductor parallel to the diaphragm
substrate 1 Form a magnetic circuit that generates a magnetic field that intersects two. The
diaphragm base 1, the magnet 3 and the magnetic plate 4 are integrally held by the fixing
member 5, and the diaphragm base 1 vibrates up and down in the figure to reproduce the audio
signal applied to the conductor 2 as a speaker Do. (Effects of the Invention) As described above,
according to the present invention, one side of an aluminum flat plate is masked with a resist
agent, and a ceramic layer is formed on the other side of the aluminum flat plate by electrolytic
deposition. After removing the agent, the conductor pattern is masked by using Photoresist i to
the exposed surface of aluminum, and the aluminum plate is immersed in a solution of acid or
alkali to form an aluminum conductor in the ceramic layer, so that it is lightweight And, a
diaphragm of a high-elasticity full-field drive type speaker is obtained.
