Description
Technical field
Present invention system is relevant with loudspeaker defined in international classification number H04R, specifically refers to a kind of loudspeaker, its
It conveniently can adjust or change the passive radiator for being configured inside loudspeakers.
Background technology
Passive radiator is also known as passive type vibrating diaphragm, and it is typically the electroacoustic device that such as sound equipment is co-located on monomer
Audio amplifier in, and allow the shared back of the body chamber of monomer and passive type vibrating diaphragm.When monomer sounding, monomer can pass in the air that back of the body chamber is compressed
Passive type vibrating diaphragm is handed to, and then drives passive type vibrating diaphragm sounding indirectly.Therefore for the back of the body the less electroacoustic device of chamber volume and
Speech, can simultaneously it add by the help of the counterweight of different weight in passive type vibrating diaphragm, the low-frequency resonant frequency of dive output sound
The resonating effect of strong back of the body chamber, and then optimize the performance of overall sound field and the spatial impression of electroacoustic device.
However, traditional electroacoustic device, the passive radiator set by it is fixedly arranged in the housing of electroacoustic device mostly
Portion, therefore traditional electroacoustic device is when dispatching from the factory, i.e., it is determined that it can be output the low-frequency resonant frequency of sound, therefore user
Or genuine is the characteristic for being difficult to simply mix suitable output sound with demand according to the hobby of indivedual users, this is right
Hindered for the trend of personalization of product is stressed at present.
The content of the invention
In view of this, it is passive set by inside the electroacoustic device it is an object of the invention to provide a kind of electroacoustic device
Radiator can easily adjustment position or replacing, use the characteristic for conveniently adjusting out suitable output sound.
In order to reach above-mentioned purpose, the invention provides a kind of electroacoustic device, it includes a housing, one is arranged at housing
Interior monomer and a passive radiator.Wherein housing is to offer a slot and one first sound hole, and monomer is jointly fixed with housing
Justice goes out the ante-chamber towards first sound hole and the back of the body chamber relative to the ante-chamber, and passive radiator is movably to be arranged at the housing
In interior back of the body chamber, and towards the monomer.
The first preferable scheme is that the passive radiator is movably to be adjusted towards or away from the direction of the monomer
It is whole.Electroacoustic device obtained by the program can easily adjust the distance between passive radiator and monomer, and then can be changed without
The output audio of electroacoustic device is adjusted on the premise of passive radiator.
A kind of specific implementation based on above-mentioned preferable scheme is：The housing is included outside the first enclosing cover and second
Lid, the two is socketed by screw thread, and the monomer and passive radiator are respectively arranged in the first enclosing cover and the second enclosing cover, by first
The adjustment of distance between passive radiator and monomer is realized in turn between enclosing cover and the second enclosing cover.Further, the housing
The first annular part and the second annular element that can mutually screw togather can also be included, first enclosing cover and the second enclosing cover are respectively with first
Annular element and the connection of the second annular element.
The first preferable scheme is：The passive radiator is inserting position by the slot positioned at the one of the back of the body intracavitary
Put and one outside the back of the body chamber leaves and moves between position.The program causes passive radiator to be convenient for changing or repair, finally
Reach the purpose of adjustment electroacoustic device output audio.
A kind of specific implementation based on second of preferred scheme is：The housing includes a rotating bar, is inserted on housing
The edge placement of groove sets jack, and axis hole is also correspondingly arranged in passive radiator, and the rotating bar is plugged in the jack, makes the passive spoke
Emitter can the rotating bar be that axis rotation and then realize is moved between position in insertion position and leaving.
Second of specific implementation based on second of preferred scheme be：The housing, which is provided with a chute, makes this passive
Radiator can be slidedly arranged on the chute, and passive radiator can slide in and out relative to housing.
The third specific implementation based on second of preferred scheme is：The housing includes the first box part and second
Box part, the two is to the both ends for being socketed in a string of fittings, it is single to be respectively equipped with one in the first box part and the second box part
Body and a slidable passive radiator, two passive radiators can slide in and out relative to the first box part.
In above-mentioned each scheme, passive radiator can use following concrete structure：The passive radiator includes a carrying
Disk, a vibrating diaphragm and a counterweight, the carrier are provided with a perforate, the vibrating diaphragm in perforate, counterweight located at the vibrating diaphragm it
On.
In above-mentioned each scheme, also settable second sound hole on the housing, second sound hole connection is described to carry on the back chamber and the external world.
Beneficial effects of the present invention are as follows：When being intended to adjust the characteristic of electro-acoustic product output sound, user or genuine
The position of movable radiator can be adjusted easily, or passive radiator is moved to an off into open position from the insertion position of script
Put to change passive radiator or part therein, whole Renewal process is relatively easy and conveniently.

Body 71 be from the first box part 711 and the second box part 712 to concatenating the both ends of part 713 and being formed to being socketed in an annular,
And communicated inside three.A monomer 72 is equiped with respectively in first box part 711 and the second box part 712, and the two is also all opened
Provided with a slot 73 so that passive radiator 74 slideably plugs wherein, it so also may achieve the effect provided for simple replacement of.
It should be noted that the side of annular concatenation part 713 outwardly also offers one the 3rd sound hole 714, the 3rd sound hole 714
Covered and connected by a tuning net 715.And when in use, can be with the first box of telescopic moving part 711 and the second box part 712
The two concatenates the region to be overlapped between part 713 with annular, thereby adjusts the outside area of the 3rd sound hole 714 to change in housing 71
The output of air and disengaging efficiency between portion and outside, and then adjust the table acoustically such as spatial impression of audio amplifier output sound
It is existing.
The fourth embodiment of the present invention, and the electroacoustic device are applied to an embodiment of audio amplifier, refer to Figure 11.This
In embodiment, housing 81 is arranged with a slot 811 so that passive radiator 82 plugs, and when passive radiator 82 is positioned at insertion
During position, the vibrating diaphragm 821 of passive radiator 82 is towards monomer 83.Side of the housing 81 away from monomer 83 offers the 4th sound hole
812, the 4th sound hole 812 is also covered and connected by tuning net 813, and making can be by the 4th sound hole with outside air inside audio amplifier
812 communicate.
It should be noted that the tuning net in each embodiment is can be changed to use wire netting depending on being actually needed.
The specific implementation of above-described embodiment only present invention, therefore its description is more specific and detailed, but can not be
And it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, not
On the premise of departing from present inventive concept, various modifications and improvements can be made, these obvious alternative forms belong to
Protection scope of the present invention.
