Abstract
A loudspeaker comprises an enclosure (2) having a baffle (7) surrounding a drive unit (4), characterised by means (3) mounting the drive unit in the enclosure (2) remote from the baffle (7).
Description
The present invention relates to a kind of loud speaker, relate more specifically to a kind of loud speaker, comprise a box-shaped box, it is cube or other shape, contains one or more loudspeaker drive units.
The purpose of this invention is to provide a kind of loud speaker that has improved.Specifically the purpose of this invention is to provide a kind of loud speaker, wherein settle the dividing plate of driver element usually, isolate with at least one driver element.
The purpose of this isolation be to stop because the output of unintentional dividing plate or owing to be installed in driver element on the same dividing plate (for example, bass driver element) output from another one and produce and a high pitch driver element for example by unintentional) the distortion that mixes the sound of exporting that causes.
But this isolation can not be repelled driver element and directly link to each other by the support or the base plate of casing with the supporting loud speaker.
For avoiding the existing people's suggestion of the problems referred to above that the several devices of high pitch are installed in the independent casing, this casing separates with the casing that contains middle pitch and bass driver element.This set comprises an additional construction expenditure and considers spendable space, might not be possible during enforcement.
By the invention provides a loudspeaker box, it has the dividing plate that encases driver element, also has in addition driver element is installed in device in the casing, be located at dividing plate away from locating.Dividing plate also can directly be installed a for example high pitch driver element, and mid that matches and/or bass driver element are not directly installed on the dividing plate.The most handy elastic sealing device between dividing plate and driver element, for example pad is as unique connection.
Cabinet design is become conventional cube box-like, and one of them driver element places on the casing rear wall, and the driver element that described separation is installed can be placed in from outstanding one or several of casing rear wall, on preferably a plurality of columns.This column is preferably taper, makes the standing wave that can be used in help decomposition (elimination) casing.Column and casing rear wall can be made into integral body, and for example can be and form by the polypropylene that is added with mica filler is molded.
High pitch loudspeaker can be contained in the mode of its mounting board between dividing plate and one or more column in the casing, thereby does not need to use securing member.
Also available at least one column comes supporting clapboard.
With reference to accompanying drawing embodiments of the invention are described, in the accompanying drawing:
Fig. 1 is the side sectional view that decomposes by loud speaker of the present invention;
Fig. 2 is the side sectional view of Fig. 1 loud speaker;
Fig. 3 shows the details A that amplifies among Fig. 2.
Illustrated loud speaker comprises a housing of being made up of cube box-shaped box 2, and casing 2 is by 7 sealings of a dividing plate, and they are all formed as the polypropylene that is added with mica filler is molded by plastic material.Be formed with several (for example 4) unitary tapered post or column 3 in casing 2 inside, it is given prominence to from casing rear wall 9 and passes casing, and its free end 12 is positioned near casing 2 leading edges 11.Tapered pole 3 can be used for eliminating the standing wave in (decomposition) casing.Low frequency drive unit 4 usefulness securing member for example bolt 16 are installed on the post 3, make it be surrounded by the hole on the dividing plate 7 13 but with the hole certain distance are arranged.An elastic sealing element 5 is inserted in 13 in hole on driver element 4 and dividing plate 7, thereby driver element 4 separates with dividing plate.Insert an elastomeric isolation sealing device at dividing plate 7 and 10,11 of casing 2 respective edges, dividing plate and casing are separated.
High frequency drive unit 8 by securing member as following closely 15 holes 14 that directly are mounted on the enclosed baffle 7.
Be equipped with Active crossover network 1 on the casing rear wall 9.
Above-mentioned design not only can be produced the loud speaker that a main driver element and dividing plate are isolated on acoustics, but also is convenient to install.Because casing in the back, thereby loudspeaker assembly can be in place easily, perhaps is automatically to install, and just can detect this loud speaker before loading onto dividing plate.
Low frequency drive unit is directly installed on can guarantees good being connected with casing that is support on the casing squab panel, this support helps to absorb the power of loud speaker.
High frequency drive unit is installed in anterior dividing plate can be guaranteed and being rigidly connected of support.Two driver element sound travels separate can guarantee when the high and low frequency unit respectively with base plate when rigidly connected, at least one the interlayer order between them.
No matter have or not high frequency drive unit, the isolation of bass driver element and preceding dividing plate to reduce the audio amplifier noise that causes owing to the dividing plate acoustic radiation.
Place a loud speaker on the common diaphragm to compare with all driver elements, above-mentioned loud speaker has the performance of having improved.
