Description
Technical field
The utility model relates to sound technique field, refers to a kind of combined type loudspeaker box device especially.
Background technology
The rigidity of audio amplifier and density are all moderate, then tonequality is optimum, the audio amplifier that reason is, low-frequency gain should be improved, because the vibrating diaphragm of loudspeaker can move forward and backward when sounding, and then the air in compression loudspeaker and audio amplifier, therefore the bleeder port buffer air that the larger loudspeaker of power have more needed is to obtain suitable damping, make low frequency enough, but sound can not the distortion because of compressed-air actuated resistance.
The inner surface of current casing on the market obtains the loudspeaker box structure of suitable damping without available buffer (diffusion, reflection or dispersion standing wave point) air.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of combined type loudspeaker box device, to solve the problems of the technologies described above.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of combined type loudspeaker box device, comprising: an outer sound box bodies, has a upper plate, a lower plate, pair of side plates, a header board and a rear plate, forms a resonant cavity therebetween; Described header board has at least one containing hole; One sounding component, is located at described containing hole; One endothecium structure, has plate after in lower plate in upper plate in, pair of inside plate and; Described interior upper plate, described interior lower plate, described described upper plate, described lower plate, the described inner surface to side plate and rear plate are located at respectively to interior plate and described interior rear plate; When described sounding component is sounded, described endothecium structure produces diffusion, reflection to the sound in described resonant cavity and disperses the harmonic inhabitation effect of standing wave point, reaches preferably audio amplifier resonating effect.
Also comprise: an internal partition, to be located between described interior upper, described interior lower plate and between described sounding component and described lower plate; A low frequency cavity is separated out between in described resonant cavity; At least one low frequency sound hole, penetrates and is located on described header board, and between described sounding component and described lower plate, described low frequency cavity is communicated with described resonant cavity and described low frequency sound hole; The bass that described sounding component sends in described resonant cavity, sends out from described low frequency sound hole through described low frequency cavity.
The beneficial effect of technique scheme of the present utility model is as follows:
The utility model can improve tonequality by harmonic inhabitation.The utility model arranges endothecium structure in sound box bodies inside outside, and when described sounding component sends the bass of different range towards described resonant cavity, endothecium structure can spread, reflects and disperse the harmonic inhabitation effect of standing wave point to bass.

Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figures 1 to 5, embodiment of the present utility model provides a kind of combined type loudspeaker box device, and it comprises: an outer sound box bodies 10, has upper plate 11, lower plate 12, pair of side plates 13, header board 14 and a rear plate 15, forms a resonant cavity 10A therebetween; Described header board 14 has at least one containing hole 141; At least one sounding component 20, is located at described containing hole 141; One endothecium structure 30, to have in one plate 34 after in lower plate 32 in upper plate 31, pair of inside plate 33 and; Described interior upper plate 31, described interior lower plate 32, described described upper plate 11, described lower plate 12, the described inner surface to side plate 13 and rear plate 15 are located at respectively to interior plate 33 and described interior rear plate 34; When described sounding component 20 is sounded, described endothecium structure 30 produces diffusion, reflection to the sound in described resonant cavity 10A and disperses the harmonic inhabitation effect of standing wave point, reaches preferably audio amplifier resonating effect.
Described endothecium structure 30 is timber structure.The utility model also comprises: an internal partition 41, to be located between described interior upper, described interior lower plate 31 and 32 and between described sounding component 20 and described lower plate 32; A low frequency cavity 41A is separated out between in described resonant cavity 10A; At least one low frequency sound hole 42, penetrates and is located on described header board 14, and between described sounding component 20 and described lower plate 32, described low frequency cavity 41A is communicated with described resonant cavity 10A and described low frequency sound hole 42; The bass that described sounding component 20 sends in described resonant cavity 41A, sends out from described low frequency sound hole 42 through described low frequency cavity 41A.
Good audio amplifier can improve low-frequency gain, reason is that the vibrating diaphragm of loudspeaker can move forward and backward when sounding, and then the air compressed in loudspeaker and audio amplifier, therefore the bleeder port buffer air that the larger loudspeaker of power have more needed is to obtain suitable damping, make low frequency enough, but sound can not the distortion because of compressed-air actuated resistance.
Loudspeaker are when sounding, the front/rear side of vibrating diaphragm can have sound, and just phase place is the phase place of 180 degree, and the two can cancel each other, so we will determine that front and back sound field separates, the air of circulation can not be had to contact, in order to avoid canceling sound, in addition, namely sound be vibration, loudspeaker also must firm being fixed in mechanism, and appropriateness add the material that can spread, reflect or disperse standing wave point a bit, vibration during sounding can be avoided to form noise.And sender is more, perforate is more large better.
When described sounding component 20 sends the bass of different range towards described resonant cavity 10A, described resonant cavity 10A planted agent is with the bass of the corresponding different range of different air pressure, just can make described sounding component 20 in the different frequency range of frequency response, have desirable audio presentation.
The utility model arranges described endothecium structure 30 at described outer sound box bodies 10 inner surface, when making described sounding component 20 send the bass of different range towards described resonant cavity 10A, bass can be offset (pressure change by described endothecium structure 30, harmonic inhabitation) about 40%, make described sounding component 20 play desirable audio presentation.
The beneficial effects of the utility model are as follows:
The utility model can improve tonequality by harmonic inhabitation.The utility model arranges endothecium structure in sound box bodies inside outside, and when described sounding component sends the bass of different range towards described resonant cavity, endothecium structure can spread, reflects and disperse the harmonic inhabitation effect of standing wave point to bass.
It is more than preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
