JP3132214U - Staggered multi double bass reflex type speaker - Google Patents

Abstract

[PROBLEMS] By setting a plurality of second cabinets to be set in a double bass reflex type, it is possible to set the frequency to be boosted in the low range in a stepwise manner. Without disturbing the sound image localization, high-quality and uniform reproduction in the low frequency range is possible.
SOLUTION: A single speaker unit enables high-quality low-frequency reproduction with no irregularities in the frequency band from a region called heavy bass to super-bass. In addition, the sound pressure level from the plurality of second ducts is slightly lower than that of the conventional type, so that a natural level heavy bass reproduction with less emphasis is realized.

Description

  The present invention provides a new proposal for the structure of a double bass reflex type enclosure aiming at high-quality reproduction of heavy bass sound in a speaker.

  The double bass reflex type is an effective method as a speaker that sufficiently reproduces the bass range that supports the musical tone, but until now the second cabinet has been set one-on-one with the first cabinet. A high reproduction level can be obtained at a frequency emphasized by the above, but on the other hand, a high-quality sound quality cannot be ensured in reproduction of a heavy bass range, for example, a level is lowered at a frequency higher than that band.

  In the double bass reflex cabinet for playing heavy bass with speakers, the bass playback area is expanded by emphasizing the sound behind the unit in two stages in the bass range, but it was set with the first and second ducts. The phenomenon in which the sound pressure decreases between frequencies is unavoidable, and it is a difficult task to continuously ensure good low-frequency reproduction. Further, if a plurality of units are used to solve this problem, there is a problem in that a disadvantage arises that reproduced sounds from the front face overlap and the sound image becomes unclear.

  By installing multiple second bass reflex type cabinets, you can set the frequency to be boosted in the low range step by step, and the sound image localization in the mid range can be achieved with one unit attached to the front. High quality and uniform reproduction in the low frequency range is possible without any interruption.

  A single speaker unit enables high-quality low-frequency reproduction with no irregularities in the frequency band over a region called heavy bass to ultra-low bass. In addition, the sound pressure levels from the plurality of second ducts are slightly lower than those of the conventional type, which realizes a natural level heavy bass reproduction with little emphasis.

Claims (1)

  In a double bass reflex type speaker, sound pressure is sent from the first cabinet to a plurality of second cabinets, and a plurality of second ducts are driven to continuously set a plurality of frequencies to be emphasized in the bass range, thereby increasing the heavy bass. A mechanism to play at level.
