DETAILED DESCRIPTION OF THE INVENTION In the present invention, a diaphragm obtained by
kneading a ceramic particle and a synthetic resin (acrylic emulsion resin) is coated by spraying or
coating, and the diaphragm is partially or entirely coated. By giving weight, even divided
vibration in the low frequency range appropriately, the frequency characteristics can be reduced
to reduce peaks and valleys, the efficiency of the speaker can be reduced, and the damping effect
of the diaphragm side effect has been clarified. The present invention relates to a speaker having
a diaphragm coated with a pottery particle-kneaded resin, which is characterized in that the
sound is reproduced. Conventionally, in the manufacture of speakers, a wide variety has been
studied. That is because there is a considerable change in the performance depending on the
shape, size, material, etc. of the diaphragm in the speaker. . If the diaphragm is made of a light
material, the difference between peaks and valleys of the frequency characteristics is large, and if
a heavy material is used, the difference between the peaks and valleys becomes relatively small.
姥, γ 忰 \ From this, it has become possible to apply 2 $ tri-stick to a part of the surface or
whole surface of the diaphragm in recent years. However, it is difficult to adjust the weight of the
diaphragm by such a method, and it has been impossible to produce a consistent highperformance speaker linked to mass production. j (in the form of sicom and synthetic wR, etc.),

performance decreases. From the above, the present invention studies these drawbacks and
advantages, and is an excellent speaker. It will be as follows if this is explained in detail. The
bottom of the frame (4) of the speaker is provided with a magnetic 101 circuit (5) at the rear of
the frame (4) and a wedge-shaped diaphragm (2) fixed at the front of the frame (4) It is
something which applies or sprays in the necessary amount or the necessary form on the inner
surface of the bowl-like diaphragm (2) except the provided protector (3). . The ceramic particlekneaded resin is obtained by kneading a ceramic particle and a synthetic resin (acrylic-based
emulsion / yron resin) produced by high-temperature firing and a clay. By spraying or coating a
mixture of ceramic particles and acrylic emulsion 4 tree mouth effect and clay on a part or the
entire surface of the diaphragm in this way, it is possible to make division vibrations particularly
in the middle and high tones of the speaker appropriate. Can be
In particular, the control sound given to the elastic diaphragm with the effect of "synthetic tree"
is used to make the reproduced sound clear and damp. Moreover, since it is mainly made of
pottery particles by high-temperature firing, there is almost no deterioration or deformation.
Therefore, the sound quality emitted from the speaker does not change permanently, and the
ceramic particles are present in the film in the form of a ring, so that the fluctuation of the
frequency characteristic caused by the action of the reflected sound can be eliminated. is there.
In addition, the fluctuation of the frequency characteristic caused by the interference of the
reflected sound wave occurring in the cabinet can be almost eliminated by applying on both sides
or the whole surface of the diaphragm. When making this pamphlet of the present invention,
during the production process of the diaphragm, it is possible to easily form an oil film for 5
ceramic particles by spraying or by brushing, 6 that is, it is adhered to the conventionally molded
diaphragm The rubber, the foamed resin, etc. are adhered by the agent, but the rubber adhered
to the diaphragm, the foamed resin, etc. greatly affect the weight or the performance of the
speaker. Since the slight difference in weight affects the performance of the speaker, it is
troublesome to remove or add the adhered rubber and the foamed resin. However, since the
present invention is spraying or brushing, it can be easily increased or decreased in weight.
Moreover, the above-mentioned ceramic particle resin has a high degree of waterproofing at the
same time as complete coating, and is not susceptible to deterioration by moisture or the like.
1イ。 Moreover, it is excellent in durability and flame retardance in combination with the
excellent adhesion of the synthetic resin, and since it is liquid, it can be used easily and easily. As
described above, the present invention can fully exhibit the performance of a bass speaker, in
particular, by using the pottery granular resin, and can bring about an effect almost the same as
natural sound. 6 recent years, radio, television, stereo, etc. is remarkable, especially in stereo,
technological advances, quality improvements are remarkable, and it is natural for consumers to
want better functionality It is The present invention provides what has been researched to meet
these needs, and is convinced that the excellent sound quality contributes to the excellent music
in the field of mental health of people.
