Definitions

  • the present invention processes the collected and reproduced sound in a hyperbolic parabolic manner, and a processing method that satisfies the immersive four-dimensional stereoscopic effect. How to double the feeling. Background art
  • the present invention uses a total of 6 speakers, such as the 5.1 channel speaker, virtual sound system, 1 center speaker, 4 front and rear, 1 cab woofer, as seen in the mainstream Dolby Sound. While using the three-dimensional sound by utilizing the TA-E900 OES device, the digital technology and the audio technology of the TAEES device are decentralized, and the TAEES device is placed in a spherical structure. Separated functions are accommodated to reproduce a complete three-dimensional acoustic four-dimensional space with only two stereo speakers. (A)
  • (A) is a spherical structure, the surface and interior of which are installed in a container made of a sound-absorbing plate and a microporous material.
  • the speakers are arranged in two directions and the angle of arrangement is a hyperbolic paraboloid, and the sound is collected in a four-dimensional space while corresponding to the structure containing the TAEES device. As a result, the above-described high sense of presence and sound image localization are maintained.
  • the second important point of the present invention lies in the speaker.
  • the stream waves emitted from the newly designed 5-plane loudspeaker have their own angles that independently perform frequency correction and generate a difference signal.
  • the directional sound emission on the five surfaces is synthesized and generated in AUTOMATIC at a fixed point at a union point, creating a sound field full of three-dimensional feeling.
  • all speakers installed in each instrument use 5-plane directivity, so that sound is collected while performing frequency correction by themselves, and the stability of the volume level is controlled by sound output from each speaker. At the intersection, the listener will experience a immersive stereoscopic effect.
  • Figure 1 shows a pure audio amplifier and a Merck-type resistance signal switching relay (0-1, 0-2, 0-3) separated and connected to a five-way directional speaker to achieve hyperbolic sound.
  • This shows the structure, and for a linear directional sound emitted from a 5-plane directional loudspeaker 1, the stream waves emitted from 2, 5, and 6 perform frequency correction at 3, 4 and 7 and 8 generate the difference signal.
  • the sound collection device centered on the 9 ⁇ 10 ⁇ 11 position provides four-dimensional sound quality with a three-dimensional feeling and a sense of presence.
  • Figure 2 shows a new speaker structure that emits five-directional finger elements.
  • 1 is the original sound speaker (microporous film)
  • 2 is a guide plate that maintains the sound emission angle on both LEFT and RI GHT
  • 3 Is a guide plate protruding between the fine hole plates 5 and maintaining an angle of right and left sound separation
  • 4 is a guide plate having a needle-like tip for direct sound emission.
  • Supernatural sound quality can be provided for large screen sound. In this way, it is possible to participate in a wide range of businesses such as broadcasting stations (televisions and radios), music CDs, cinemas, DVDs, TV games, concerts, events, PC sound plasters, outdoor advertising, welfare, etc.

Abstract

L'emploi combiné d'un système sonore virtuel et d'un nouveau haut-parleur directif à cinq faces permet de surmonter les insuffisances des techniques existantes de reproduction du son. La qualité sonore stéréophonique obtenue bouleverse la production mécanique de sons utilisée jusqu'alors en mettant l'accent sur le traitement parabolique hyperbolique par l'angle de génération du son. Les ondes sonores produites par les cinq faces se déplacent selon des angles propres, des signaux différentiels sont produits, une correction de fréquence est obtenue par des débits sonores uniques et le son ainsi recueilli permet de reproduire un système sonore efficace en matière de son réel stéréophonique.
