Detailed description of the invention
What refer in accompanying drawing is graphic, and wherein identical element numbers represents identical assembly.The following description is based on the illustrated specific embodiment of the invention, and it is not construed as other specific embodiment that the restriction present invention is not detailed herein.
Refer to the structural representation of the first preferred embodiment of the speaker system that Fig. 1, Fig. 1 are the present invention.The speaker system 10 of this preferred embodiment includes sound box body 11, speaker 12, main body vibrating diaphragm 13, soft drive circuit 14 and connects shell fragment 15.
An accommodation space 111 and the breach 112 connected with accommodation space 111 it is provided with in sound box body 11；Speaker 12 is arranged in accommodation space 111, and the face of speaking of speaker 12 is just to breach 112；Main body vibrating diaphragm 13 is arranged on breach 112 place, for strengthening the low-frequency effect of speaker 12；Soft drive circuit 14 is arranged on the bottom holding space 111, is used for driving speaker 12；Connect shell fragment 15 to be used for connecting soft drive circuit 14 and speaker 12.
Wherein being provided with the diaphragm of loudspeaker 121 on the face of speaking of speaker 12, the distance of the diaphragm of loudspeaker 121 and main body vibrating diaphragm 13 is more than the unilateral Oscillation Amplitude sum of the unilateral Oscillation Amplitude of the diaphragm of loudspeaker 121 and main body vibrating diaphragm 13.Here unilateral Oscillation Amplitude refers to that the diaphragm of loudspeaker 121 or main body vibrating diaphragm 13 are under the sound driver of speaker 12, upwards the ultimate range of vibration or vibration downwards.
For the vibration effectiveness of provider's vibrating diaphragm 13, this main body vibrating diaphragm 13 is preferably poroid vibrating diaphragm or thin film vibrating diaphragm.
When the speaker system 10 of this preferred embodiment uses, speaker 12 is driven by soft drive circuit 14 by connecting shell fragment 15, and speaker 12 can send the sound of various frequency range.Wherein the low-frequency sound in the sound of various frequency ranges can be strengthened by the diaphragm of loudspeaker 121 spoken on face of speaker 12.When the sound of various frequency ranges passes through the breach 112 of sound box body 11 subsequently, it is arranged on the main body vibrating diaphragm 13 on the breach 112 of sound box body 11 and can proceed the low-frequency sound in the sound of various frequency ranges to strengthen.So can effectively reduce the cut-off frequency of the low-frequency sound of speaker system 10, thus enhancing the sounding effect of the low-frequency sound of speaker system 10.
Preferably, the distance unilateral Oscillation Amplitude sum more than the unilateral Oscillation Amplitude of the diaphragm of loudspeaker 121 and main body vibrating diaphragm 13 of the diaphragm of loudspeaker 121 and main body vibrating diaphragm 13 is set here, to avoid the mutual sounding collision when vibration of the diaphragm of loudspeaker 121 and main body vibrating diaphragm 13, thus affecting the sounding effect of speaker system 10.
The speaker system of this preferred embodiment strengthens the low-frequency effect of speaker system by the setting of main body vibrating diaphragm, thus improving the result of broadcast of the middle bass of speaker system.
