Abstract
The present invention relates to a woofer loudspeaker system which is composed of the woofer speaker unit and cavity. The woofer loudspeaker system is characterized in that the woofer speaker is positioned behind the cavity so as to form the postpositional woofer speaker. The method can prevent the loudspeaker from harms effectively. Also, it helps to raise low frequency response of the system.
Description
Technical field
The present invention relates to a kind of woofer system, be made up of woofer unit and cavity, it is characterized in that the woofer unit places the cavity back side, vibrating membrane is outside, forms rearmounted woofer.
Background technology
Existing woofer system, its loudspeaker unit mostly places the front of cavity, also has to place the side.The shortcoming of making is outside loudspeaker unit is directly exposed to like this, and its paper disc face and dust cap are stabbed, break easily, even is deliberately pressed flat by curious child.The design that also has is with woofer unit placed face down, but this mode needs to load onto suspension column below the casing of system: to get enough sound reproduction spaces discard.
Summary of the invention
The object of the invention is to provide a kind of woofer system schema of rearmounted loudspeaker unit.
According to the solution of the present invention, the woofer unit places the cavity back side, and vibrating membrane is outside, forms rearmounted woofer.The way of this woofer unit postposition can avoid loud speaker to come to harm effectively, but also helps to improve the LF-response of system.
For attractive in appearance, binding post and lead-in wire are all rearmounted usually, so the back of system kept a part of space usually and between the house sidings, thereby have reserved enough sound reproduction spaces for rearmounted loudspeaker unit.If lead-in wire and binding post need be located at the cavity front, just correspondingly set up isolation structure, make between loud speaker and the wall and keep at a distance.Allow some leeway when perhaps putting.
The present invention can be combined into the full range speaker system with other speaker systems, and specific practice is to set up one or more separate speaker unit or speaker system in the front of its cavity, formation multichannel loudspeaker system.Such speaker system compound mode, more effectively broadening frequency band, realized the sound reproduction of whole audiorange.
According to a scheme of the present invention, described cavity and woofer unit among the present invention add paraphase hole, constitute single chamber or multi-cavity resonance body woofer system, are called the cavity body structure of inverted phase type or multistage inverted phase type again.Sound absorption thing, vibration damping baffle and support column can be installed in the described cavity, shake and standing wave to remove harmful case.Paraphase hole can be located at the front of cavity, also can be located at the back of cavity.
According to a scheme of the present invention, the described cavity among the present invention is a kind of cavity body structure of sealing, does not have sender, and it and woofer unit constitute closed woofer system.Sound absorption thing, vibration damping baffle and support column can be installed in the described cavity, shake and standing wave to remove harmful case.
According to a scheme of the present invention, described cavity and woofer unit among the present invention add upper channel and sender, constitute horn formula woofer system.The sectional area of horn changes, and obeys the Bessel function rule along the variation of the exhibition direction of wriggling.The cross sectional shape of this horn can be circular, also can be rectangle, and each cross section can be wide (in the exhibition middle section of wriggling long-pending change but width does not change), also can be not wide; The path of the exhibition of wriggling can be straight, also can be designed to folding mode.Modal is " wide collapsible horn ", can directly be spliced in audio amplifier with baffle plate in design.Above various forms is the same substantially from acoustic efficiency.Sound absorption thing, vibration damping absorption version and support column can be installed in the described cavity, can adhere to the sound absorption thing on the conduit wall, shake and standing wave to remove harmful case.Described sender can place the cavity front, also can be located at back or other faces of cavity.
According to a scheme of the present invention, described cavity and woofer unit among the present invention add upper channel and sender, constitute labyrinth type woofer system, be called " labyrinth audio amplifier " again, it is some baffle plates that have been crisscross arranged in audio amplifier, from the side section, seem the passage of having adorned complications at the rear of loud speaker, its channel cross-sectional area is kept constant in the exhibition of wriggling substantially.Sound absorption thing, vibration damping baffle and support column can be installed in the described cavity, can adhere to the sound absorption thing on the conduit wall, shake and standing wave to remove harmful case.Described sender can place the cavity front, also can be located at back or other faces of cavity.
