DESCRIPTION JPS61113397
[0001]
TECHNICAL FIELD The present invention relates to a diaphragm of a square speaker applied to
general audio equipment. Prior Art Conventionally, the diaphragm of this type of square speaker
has a structure as shown in FIG. 4 to FIG. That is, the bonded portion 3 with the edge 2 bonded to
the peripheral surface of the diaphragm main body 1 has a structure in which the peripheral
surface is bonded with a substantially uniform width. If the configuration of this diaphragm is the
problem that the invention is intended to solve, anti-resonance occurs because the corner portion
of the diaphragm main body 1 is weak when incorporated and operated as a speaker. Although it
is conceivable to increase the weight of the diaphragm in order to eliminate this problem, the
problem of a decrease in efficiency occurs. Therefore, the present invention is to provide a
diaphragm of a square speaker in which corner portions can be strengthened and anti-resonance
can be reduced without increasing the weight of the diaphragm. Means for Solving the Problem
In order to solve the problem, the present invention is to form a corner of the square diaphragm
by making the inner diameter of the edge bonding portion circular and octagonal at the bonding
portion of the diaphragm and the edge. It reinforces. In the case of a square diaphragm, the
shape of the cross section of the diaphragm is different for each angle, and the length from the
temporary vibration center to the periphery of the diaphragm is different compared to the
circular diaphragm for operation. Since the inner diameter of the edge bonding portion is made
circular and octagonal and is bonded to the diaphragm, the corner portion becomes strong and
distortion can be reduced. EXAMPLE A diaphragm of a square speaker according to an example
of the present invention will be described below. As shown in FIGS. 1 to 3, although a rectangular
edge 5 is adhered to the circumferential surface of the diaphragm main body 40 having a
rectangular structure, the edge of the diaphragm 5 is strengthened in order to strengthen the
corner portion of the diaphragm main body 4. The corner portion of the square cone is
reinforced by bonding to the diaphragm main body 4 the circular and hexagonal inner diameter

of the bonding portion 6. Effects of the Invention As described above, the present invention can
reinforce anti-resonance without increasing the weight of the diaphragm by reinforcing the
corner portion of the rectangular diaphragm body with an edge, and can be reliable with respect
to amplitude. Also improve.
