Description

The present invention relates to a speaker device in which the outer periphery of the speaker body from the cone base portion to the tip peripheral portion of the speaker body is covered with tapered ceramics.

Conventionally, audio speaker bodies that are particular about sound quality have been developed. For example, the speaker body is housed in the front opening of a box-shaped cabinet, and the cabinet is made of a material such as stone to reduce resonance due to natural sound.

Conventionally, in order to improve the sound quality generated from the speaker body in this way, various ingenuity has been made to the speaker itself, an acoustic case containing the speaker body, and the like.

For example, Patent Document 1 is configured such that the upper end opening of a ceramic jar is closed with a speaker unit so that the sound generated from the unit can be reflected in a predetermined direction by a reflection adjusting plate provided above the unit. At the same time, the configuration in which the sound quality radiated from the unit can be controlled by providing an acoustic adjusting means such as porous urethane or cotton in the internal space of the jar is disclosed.

Further, in Patent Document 2, in a porcelain speaker unit, in order to use the porcelain exterior portion as a resonator, the speaker and the porcelain body are fixed with double-sided adhesive tape, so that the sound generation portion and the porcelain are formed. fixing the positional relationship between the parts discloses the structure to improve the sound quality.

However, in each case, the acoustic reaction inside the acoustic case that houses the speaker body is not sufficient, and the capacity of the speaker itself is increased or a high-performance acoustic speaker is used, but it does not satisfy the audience. There wasn't. It is considered that the cause is that the sound generated from the speaker is once transmitted to the acoustic space, and then the sound is generated in the sound room by sound amplification means.

Therefore, in the present invention, the sound is generated from the speaker body by surrounding the outer periphery of the space as close as possible to the cone part, which is the sound generating part of the speaker body, with a tapered tubular clay unglazed cover body for sound amplification and sound quality improvement. The purpose of the present invention is to provide a speaker device capable of producing a sound that has never been experienced before by improving the quality of the sound to be produced.

In the present invention, the acoustic case containing the speaker body having a tapered tubular clay unglazed cover on the outer circumference is a cylindrical acoustic case formed in a cylindrical shape, and an acoustic hole for acoustic diffusion is formed in the central peripheral wall thereof. It is characterized in that speakers with unglazed cases are arranged on both end surfaces of the cylindrical acoustic case.

In the present invention, the left and right sides of the acoustic holes are partitioned by a perforated wall having a plurality of acoustic flow holes in the cylindrical acoustic case, and the perforated adjustment plate having the adjustment acoustic flow holes overlapping the perforated wall is rotatable. It is characterized in that the acoustic flow amount can be adjusted by adjusting the coincidence between the acoustic flow hole of the perforated wall and the adjustment acoustic flow hole of the perforated adjustment plate.

The present invention is characterized in that the porous adjusting plate is configured to be operable from the outside of the cylindrical acoustic case via a gear meshing mechanism.

According to the speaker according to the present invention, the bass passes through the inside of the support cylinder base and the pottery case and is circulated to the outside. Has the effect of being able to. In addition, the sound emitted from the vibration of the cone base is absorbed by the fine holes of the tapered tubular clay unglazed cover body with front and rear openings, and at the same time, a soft reverberant sound is formed to prevent the generation of sharp and pointed sound. can.

Furthermore, due to the special material that is the soil material of the clay unglazed cover body, the bass that vibrates and oscillates at the cone base of the bass speaker body reverberates softly in the clay unglazed cover body and enters the acoustic case to enter the mid-high range. The sound quality is like an ensemble with a sense of realism mixed with the soft echoes of. At the same time, the soft bass is radiated upward from the support cylinder base, which has the effect of allowing the listener to fully feel the power of the bass.

The gist of the present invention is structured as follows. That is, the present invention is a speaker with a unglazed case configured by providing a tapered tubular clay unglazed cover body with front and rear openings on the outer periphery of the speaker body so as to cover from the cone base to the tip edge of the speaker body. The present invention relates to a speaker device characterized by.

Further, the clay unglazed cover body of the speaker with the unglazed case is characterized in that it is formed by baking the clay-molded vessel without glaze.

With the acoustic case containing the speaker body having on the outer periphery of the cover body of Te supermarkets cylindrical clay biscuit a cylindrical acoustic case formed in a cylindrical shape, in the center wall to form a sound hole of acoustic diffusion, cylindrical acoustic It is characterized in that speakers with unglazed cases are arranged on both end surfaces of the case.

Further, in the cylindrical acoustic case, the left and right sides of the acoustic holes are partitioned by a perforated wall having a plurality of acoustic flow holes, and a perforated adjustment plate having an adjustment acoustic flow hole overlapping the perforated wall is rotatably applied. It is characterized in that the acoustic flow amount can be adjusted by adjusting the coincidence between the acoustic flow hole of the perforated wall and the adjustment acoustic flow hole of the perforated adjustment plate.

Further, the porous adjustment plate is characterized in that it can be operated from the outside of the cylindrical acoustic case via a gear meshing mechanism.

Hereinafter, examples of the present invention will be described in detail with reference to the drawings.
