Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a wide-range speaker that spreads the sound of the speakers over a wide area, and headphones that can always adjust the volume of the left and right speakers equally regardless of where you are seated in a circular music venue.

Conventional speakers have the disadvantage that the sound can only be transmitted from the front, so most people who are not in front of the speaker cannot hear it.

(T) Furthermore, at a venue such as a concert, are the front left and right sides? Even if these speakers come to the venue, the majority of people may not be able to hear true stereo music.

The structure is such that a funnel-shaped ceramic resonator is installed to diffuse the sound from the speaker over a 360° or wide area.

In addition, the present invention provides headphones that use ceramics for the reverberant body and adjust the sound volume of sea bream etc. at the bottom so that it is always even.

(3) Structure of the invention The present invention will be explained as follows based on the drawings.

(A) Whole-area speaker with a bowl-shaped reverberant installed Figure 1 is a cross-sectional view of the bowl-shaped ceramic reverberant of the present invention installed in the front of the speaker, with a circular sound quality improving member (2) made of copper or the like at the bottom. ) bowl-shaped ceramic reverberant (1)
This is a full-area speaker that is installed in front of the speaker cone and can spread the sound from the speaker over a 360° area.

A cylindrical noise prevention band (3) is installed around the outer periphery between the speaker and the reverberant (1) to prevent noise, and the reverberant (1) is fixed to the speaker with screws. . FIG. 2 is a partially cutaway view of the noise prevention band (3).

Conventional speakers are directional, so the sound can only be transmitted from a certain angle in front of the radio, but with the all-area speaker of this invention, the sound is spread over 360 degrees around the radio. Everyone can hear the audio.

In addition, in order to convey news from government offices using speakers, several speakers at different angles are installed on a single pillar to communicate to residents in the area, but if the whole area speaker of this invention is used, With just one speaker, it is possible to reach residents throughout the area.

At schools, companies, venues, temples, churches, etc., if you install this wide area speaker on the ceiling in the center of the room, you can give lessons, guidance, etc.
This allows everyone to fully listen to lectures and sermons, which has the effect of improving academic performance, efficiency, and moral sense.

As shown in FIG. 5A, a radio equipped with this wide area speaker is effective not only for listening to broadcasts and music, but also as a decoration.

As shown in Figure 5B, a compact disc or cassette tape is attached to a radio equipped with this wide area speaker and placed on a Shinto altar or Buddhist altar to record books, scriptures, prayers, etc.
When visiting a shrine while following the scriptures, both adults and children naturally develop a sense of religion and morality, and have the advantage of being able to recite the scriptures well. In this case, it would be even more effective to decorate the top of the radio with flowers, etc., and to engrave the emblem of a member of each religion or family on the front lid for compact discs or tapes.

As shown in Figure 4, in a music venue, the wide-area speaker of the present invention is installed in the center, and music is played from the right direction, and several speakers placed on the outer periphery play music from the left direction. By arranging the seats so that the wide-area speaker is on the right and the outer speaker is on the left, viewers can hear true three-dimensional sound.

This area-wide speaker not only diffuses the sound over the entire area, but also uses ceramics for the bowl-shaped reverberant (1) and copper on the bottom to improve the sound quality, so you can enjoy excellent sound quality. I can listen to things such as If this sound quality improving body (2) is made of an alloy of gold and copper, the sound quality will be further improved dramatically.

(b) Wide-area speaker equipped with a funnel-shaped resonator Figure 6 is a cross-sectional view of a wide-area speaker equipped with a funnel-shaped ceramic reverberant (1'). Circular sound quality improver (2') made of copper or other material with a circular hole drilled in it
is attached, and a truncated conical noise prevention shade (
3') and secure the speaker and the reverberant (1') with screws.

FIG. 7 is a partially cutaway view of the noise prevention shade (3') of this wide area speaker.

This wide-area speaker has a funnel-shaped reverberant (1'), and as shown in Figure 7.8, the reverberator (1') comes out in front of the speaker box board, so the sound from the speaker can be heard both in front and to the side. It has the characteristic of being diffused in different directions, and stereos and radio-cassette players equipped with this speaker have a further expanded sound spread, allowing you to hear three-dimensional sound with a sense of realism.

If an alloy of copper and gold is used for the reverberant (1'), the sound quality will be dramatically improved.

(1) Volume Adjustable Headphones As shown in Figure 9, these are headphones that allow you to freely adjust the volume from the left and right speakers to the left and right sides.

Several crescent-shaped thin plates (7) made of plastic or other materials that do not vibrate at all even when exposed to sound waves are assembled in a ring shape and installed on the left and right headphones (6), and the adjustment knobs (7) installed on the outer periphery of the headphones (6) These volume-adjustable headphones have a structure in which the size of the hole in the headphones (6) can be freely adjusted by rotating the headphone (8). A circular hole is formed in the outer part of the head system (6) so that the sound from the speaker directly enters.

As shown in Figure 4, when you listen to music at a seat in the center of both the left and right speakers in a circular music venue, etc., you get true 3D sound, but when the seats are more biased to either the left or right, The volume from the speakers closer to you is louder, and the volume from the speakers farther away is lower, creating an imbalance between the volumes in your left and right ears and preventing true 3D sound.

In such a case, if you wear the volume adjustment headphones of this invention and turn the volume adjustment knobs (8) of the left and right headphones (6) to adjust the volume to the optimal level for your ears, you can adjust the volume to the left and right no matter where your seat is. Since the volume of the speakers can be adjusted to a well-balanced volume that suits each viewer, all viewers can be immersed in wonderful three-dimensional music.

(4) Effects Since the wide-area speaker of this invention is installed on the entire surface of the bowl-shaped or funnel-shaped ceramic reverberant speaker cone, it has the effect of dispersing the sound over the entire 360'' area or over a wide area in the front and lateral directions. Furthermore, the sound quality is particularly excellent because the reverberant body is made of ceramics and a sound quality improving material such as copper is installed at the bottom.

(a) A full-area speaker with a bowl-shaped reverberant has a sound output of 36
Since it is diffused at 0°, it is effective when used in schools, companies, venues, temples, etc.

Furthermore, when using this area-wide speaker in municipalities to notify residents, there is the advantage that only one speaker can be used to notify the entire area, whereas conventionally several speakers were installed on the same pole.

A radio equipped with this area-wide speaker can of course be used as a general radio, but it can also be placed on a Shinto altar, Buddhist altar, etc., decorate the top with flowers, etc., and install a tape or compact disc in the casing, and play scriptures, prayers, etc. when worshiping. It is valid.

In a circular music venue, etc., place this wide-area speaker in the center to output music from the right direction, and a few speakers on the periphery to output music from the left direction, so that the right ear can hear the sound from the left direction. If you arrange your seat so that you can hear the sound with your left ear, you will be able to hear true 3D sound.

(b) A wide-range speaker with a funnel-shaped reflector has the advantage that the sound is diffused both forward and sideways, so if it is installed in a stereo or radio-cassette player, the sound range will be further expanded and you will be able to hear true three-dimensional sound.

(c) When listening to music in a circular music venue, you can hear true 3D sound if your seat is in the center of both speakers, but you can hear true 3D sound if your seat is biased towards one of the speakers. can't hear it.

In such cases, if you wear the volume-adjustable headphones of this invention, you can use the sound fit adjustment knob to adjust the volume of both speakers to the optimal sound level for you, no matter what seat you are assigned to. The wonderful 3D sound has a hypnotic effect.
