[Purpose] Sound pressure is generated when the diaphragm itself, which is the diaphragm of the
horn driver, vibrates, but because the attached portion is a soft resin such as plastic, it causes
deflection and unnecessary vibration to cause deterioration in sound quality. In order to prevent
that, a metal frame is made and a sound quality is improved by reinforcing an attachment part. A
diaphragm (1) is attached to a screw to a speaker body (2), and a metal fitting such as 4 is
produced and tightly fixed in order to reinforce the attachment portion (3). [Selected figure]

Diaphragm stabilizer for horn driver
In the present invention, by attaching an instrument to a fixed portion of a diaphragm which is a
vibration plate of a horn driver, it is possible to improve sound quality by making it possible to
firmly fix closely. Conventionally, the diaphragm (diaphragm) is made of a resin such as plastic
and fixed with a few screws, but since it is a resin, it is soft, and deflection and vibration occur,
which may have an adverse effect on the sound. The present invention aims to improve the
sound quality by fixing the diaphragm more firmly. In the prior art, the diaphragm (diaphragm) 2
is fixed to the horn driver main body 1 with a few screws 3. However, it is preferable to hold the
diaphragm fixing place with a thicker metal frame 4 In order to be fixed. [0004] In this way, the
diaphragm is firmly fixed, and unnecessary vibration and deflection are eliminated, whereby the
sound quality is improved. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional
