Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.
A kind of acoustic apparatus structural representation that Fig. 1 provides for the utility model embodiment.
This acoustic apparatus comprises loud speaker bass unit 6 and loud speaker voice unit 2, and the middle position of the vibrating diaphragm 4 of loud speaker bass unit 6 is provided with phase plug 5; The vibrating diaphragm of loud speaker voice unit 2 is just placed phase plug 5 at a certain distance.It should be noted that, because also not all loud speaker bass unit all comprises phase plug, the technical program requires the bass unit with phase plug.This is because phase plug is not together vibrated with vibrating diaphragm, and under equivalent constructions, use the vibrating diaphragm of the bass unit of phase plug closer to piston vibration, sensitivity is higher; And phase plug effectively can improve the heat radiation of voice coil loudspeaker voice coil, especially metal phase plug is inherently conducive to inner heat conduction out.And traditional dustproof cover structure, because dust cap can form an air cavity behind, diaphragm oscillations meeting reverse compression or this air cavity that stretches, thus reduce the efficiency of loud speaker.Therefore compared to dust cap, phase plug structure has high sensitivity, the advantage of easy heat radiation.
Wherein, the distance between the vibrating diaphragm of loud speaker voice unit 2 and phase plug 5 can regulate according to applicable cases, such as, and can according to the distance between loudspeaker high frequency energy directive property range regulation loud speaker voice unit 2 and phase plug 5.
Above-mentioned acoustic apparatus passes through the scattering object of the phase plug of loud speaker bass unit as the radiation of loud speaker voice unit high-frequency energy, realize being uniformly distributed of loud speaker voice unit high-frequency energy, and by regulating the distance between the vibrating diaphragm of loud speaker voice unit and phase plug, adjust the scope of loud speaker voice unit high-frequency energy directive property.
The scenario-frame of the utility model embodiment is simple, cost is low, can effectively reduce the volume of acoustic apparatus, improve portability.
As Fig. 1-Fig. 3 jointly shown in, the shape of phase plug 5 can comprise centrum shape, spheroid form, spheroid shape; Obviously these shapes are only schematic, are not particularly limited in the utility model to the shape of phase plug.
In an embodiment of the present utility model, phase plug 5 can carry out the distortion of structure and height according to concrete application demand, to regulate and control high-frequency energy distribution.As shown in Figure 4, be a kind of schematic diagram of control phase cone height, in actual applications, can according to the height of concrete application demand control phase cone 5.
It should be noted that; the utility model embodiment is including, but not limited to the phase plug of above-mentioned shape; as long as the user demand of loud speaker bass unit can be met, simultaneously again can the equally distributed phase plug of high-frequency energy of additional loudspeaker voice unit all in protection range of the present utility model.
In another monogon embodiment of the present utility model, the top of phase plug 5 flushes with vibrating diaphragm 4 edge of loud speaker bass unit 6, to make the structure of acoustic apparatus more compact.It should be noted that, according to actual needs, the top of phase plug also can below or above the vibrating diaphragm edge of loud speaker bass unit, and this use new embodiment is including, but not limited to the layout type of above-mentioned phase plug and loud speaker bass unit vibrating diaphragm.
In a specific embodiment of the present utility model, loud speaker voice unit is ball top type voice unit 2 fixing bottom, and acoustic apparatus also comprises convex ball ceiling hold 1; The bottom of described loud speaker voice unit 2 is fixed on convex ball ceiling hold 1.The main effect of this convex ball ceiling hold makes loud speaker bass unit acoustic energy to surrounding homogeneous radiation, and can also be used for fixing loud speaker voice unit.But it should be noted that; loud speaker voice unit is not limited to ball top type; ball ceiling hold is also not limited to convex; as long as loud speaker bass unit acoustic energy can be made to surrounding homogeneous radiation, other shapes that can reach the acoustical behavior of practical application are also in protection range of the present utility model.
Loud speaker bass unit 6 comprises ring 3, and ring 3 is connected with the vibrating diaphragm 4 of loud speaker bass unit 6, with the vibration of the vibrating diaphragm 4 of additional loudspeaker bass unit 6; The installed part of ring-type is had with fixing loud speaker bass unit 6 in the external mounting of ring 3.
In the present embodiment, the operation principle of acoustic apparatus is: when the signal of telecommunication acts on acoustic apparatus, along with the transient change of the signal of telecommunication, the voice coil loudspeaker voice coil of loud speaker bass unit 6 and loud speaker voice unit 2 promotes corresponding vibrating diaphragm respectively and does corresponding vibration, wherein loud speaker bass unit 6 by conversion after acoustical signal after the convex ball ceiling hold 1 of acoustic apparatus acts on, to surrounding homogeneous radiation.Simultaneously, loud speaker voice unit 2 by conversion after acoustical signal after the phase plug 5 of loud speaker bass unit 6 acts on, to surrounding homogeneous radiation, to reduce the decay of high-frequency energy, improve the high-frequency energy distribution of acoustic apparatus, 360 ° that realize horizontal or vertical direction are pointed to entirely.
A kind of sound box system structural representation that Fig. 5 provides for the utility model embodiment.
This sound box system comprises voice box casing 7 and the acoustic apparatus described at least one technique scheme.
Wherein, voice box casing 7 is for supporting and fixing loud speaker voice unit 2 and loud speaker bass unit 6.Particularly, loud speaker voice unit 2 is fixed on voice box casing 7 by convex ball ceiling hold 1, and loud speaker bass unit 6 is fixed on voice box casing 7 by the ring-type installed part of ring 3 external mounting.
In sum, the utility model discloses a kind of acoustic apparatus and a kind of sound box system.By the middle position of the vibrating diaphragm at loud speaker bass unit, phase plug is set, as the scattering object of loud speaker voice unit high-frequency energy radiation, the dust cap that replacement traditional scheme is set of this phase plug, the volume of sound box system can not be increased, and phase plug with the vibration of membrane and vibrating of shaking of loud speaker bass unit, can not can improve the sensitivity of loud speaker bass unit vibrating diaphragm; And by the vibrating diaphragm of loud speaker voice unit is just placed phase plug at a certain distance, when signal of telecommunication effect, loud speaker voice unit can by the phase plug effect backward surrounding homogeneous radiation of the acoustical signal after conversion through loud speaker bass unit, reduce the decay of high-frequency energy, realize being uniformly distributed of sound box system high-frequency energy, and then the best tonequality of expansion audio amplifier listens to region, improves spatial impression and the sense of reality of playback sound.Acoustic apparatus structure of the present utility model is simple, volume can be effectively reduced, reduce production cost, improve portability, and by arranging one or more acoustic apparatus of the present utility model in sound box system, 360 ° that can realize sound box system high-frequency energy are pointed to entirely.
The foregoing is only preferred embodiment of the present utility model, be not intended to limit protection range of the present utility model.All do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., be all included in protection range of the present utility model.
