Abstract
A loudspeaker system is composed of the woofer speaker unit and cavity. The character is 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
The present invention relates to a kind of speaker 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.
Existing speaker 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.
The object of the invention is to provide a kind of speaker system scheme 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.
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, 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, described cavity among the present invention and woofer unit constitute closed speaker 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 the horn loudspeaker system.The exhibition of the wriggling rule of its channel cross-sectional area is obeyed Bessel function, and 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, shakes 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 the labyrinth loudspeaker system.Its channel cross-sectional area is kept constant in the exhibition of wriggling substantially, and 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, shakes 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.
Accompanying drawing 2 has provided multichannel loudspeaker system schematic of the present invention, and the vibrating diaphragm back of woofer unit [1] butts up against cavity [2], and woofer unit [1] in the face of the wall [3] in room, binding post [4] and lead-in wire [5] all are positioned at the back of cavity.An independently speaker system [6] is set up in the front of cavity [2], constitutes the multichannel loudspeaker system.Here speaker system [6] is used for broadcasting 200Hz with upper frequency sound.
Accompanying drawing 3 has provided the speaker system schematic diagram of single chamber of the present invention inverted phase type, the vibrating diaphragm back of woofer unit [1] butts up against cavity [2], woofer unit [1] is in the face of the wall [3] in room, and binding post [4] and lead-in wire [5] all are positioned at the back of cavity.Be provided with a paraphase hole [7] on the front panel of cavity [2], the inwall of cavity has been set up sound absorption thing [8], vibration damping baffle [9] and support column [10].
Accompanying drawing 4 has provided enclosed speaker system schematic diagram of the present invention, and the vibrating diaphragm back of woofer unit [1] butts up against cavity [2], and woofer unit [1] in the face of the wall [3] in room, binding post [4] and lead-in wire [5] all are positioned at the back of cavity.The inwall of cavity has been set up sound absorption thing [8], vibration damping baffle [9] and support column [10]
Accompanying drawing 5 has provided the speaker system schematic diagram of horn formula of the present invention, for increasing sound pressure level, the quantity of woofer unit [1] is 2, its vibrating diaphragm back butts up against cavity [2], woofer unit [1] is in the face of the wall [3] in room, and binding post [4] and lead-in wire [5] all are positioned at the back of cavity.Cavity [2] is gone up and is connected road [11] and sender [12], constitutes the horn loudspeaker system.The exhibition of the wriggling rule of its cross-sectional area is obeyed Bessel function, and sender [12] places the front of cavity [2].
Accompanying drawing 6 has provided mazy speaker system schematic diagram of the present invention, and the vibrating diaphragm back of woofer unit [1] butts up against cavity [2], and woofer unit [1] in the face of the wall [3] in room, binding post [4] and lead-in wire [5] all are positioned at the back of cavity.Cavity [2] is gone up and is connected road [11] and sender [12], constitutes the labyrinth loudspeaker system.Its cross-sectional area is constant, and sender [12] places the front of cavity [2].
