Description
Technical field
The present invention relates to the anti-sound of a kind of miniature bone conduction device and reveal sound insulation chamber.
Background technology
The operation principle of bone conduction earphone is the vibration of contact skin portion, promote tissue, the seismaesthesia produced directly is transferred to antennal nerve thus hears sound, but the part not contacting human epidermal also can promote air, thus creating air-borne sound, this air sound is leakage sound.Reveal sound and generally can not have influence on other people; but in some occasion; such as to protect individual privacy when using bone conduction device communication, or not think that this time " anti-sound leakage " just seems very important because " leakage sound " has influence on other people too greatly.Existing miniature bone conduction device does not all arrange this type of anti-acoustic device.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides the anti-sound of a kind of miniature bone conduction device and reveals sound insulation chamber, can solve the problems of the technologies described above completely.
The technical scheme solved the problems of the technologies described above is as follows:
The anti-sound of miniature bone conduction device reveals sound insulation chamber, comprise the anti-sound leakage device of inner cover, strutting piece, the anti-sound leakage device of outer cover and air barrier, the anti-sound leakage device of described inner cover comprises base and cambered surface, described base is circular configuration, described cambered surface is vertically arranged along the circumference on base, and the base described in surrounding, the anti-sound leakage device of inner cover described in described outer cover anti-sound leakage device surrounds, described inner cover anti-sound leakage device is connected by strutting piece with the upper end of the anti-sound leakage device of outer cover, the lower end of described inner cover anti-sound leakage device and the anti-sound leakage device of outer cover forms air barrier.
Described strutting piece is loop configuration.
The anti-sound leakage device of described inner cover is composite noise-absorbing material.
The anti-sound leakage device of described inner cover is nylon.
Structure of the present invention is simple, and being the anti-sound leakage device about preventing bone conduction earphone and other wearable device sound of osteoacusis from revealing, being mainly used in the shell of bone conduction earphone, this device adopts multilayer material, can effectively reduce the leakage sound of bone conduction device.
Wherein, the anti-sound leakage device of inner cover, adopt composite noise-absorbing material, this material can effectively reduce the sound produced by bone-conduction speaker vibration promotion air, be connected by strutting piece on the top of inner cover anti-sound leakage device with the anti-sound leakage device of outer cover, the effect of this strutting piece is to isolate the anti-sound leakage device of outer cover, makes to form air barrier in the middle of built-in anti-sound leakage device and the anti-sound leakage device of outer cover.The effect of outer cover anti-sound leakage device is: sound is after the anti-sound leakage device of inner cover and air barrier, and sound and seismaesthesia are all effectively decayed.
Bone-conduction speaker is when work, seismaesthesia promotes air thus produces sound, although the anti-sound leakage device of inner cover adopts composite noise-absorbing material, but the seismaesthesia produced when bone-conduction speaker work still can drive the anti-sound leakage device of inner cover produce resonance and send faint sound and seismaesthesia, and the faint sound that strutting piece can effectively prevent the anti-sound leakage device of inner cover from producing because of bone-conduction speaker vibration directly conducts to the anti-sound leakage device of outer cover.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is cross-sectional view of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is bone-conduction speaker equipment sounding effect simulation schematic diagram;
In figure: 1 is the anti-sound leakage device of inner cover, 2 is strutting piece, 3 is the anti-sound leakage device of outer cover, 4 is air barrier, and 5 is base, and 6 is cambered surface, 11 is bone-conduction speaker audible devices, be sound generation source, 12 is that the anti-sound of miniature bone conduction device of the present invention is revealed every sound cavity apparatus, and 13 be that to simulate radius be the sense of hearing of 30cm.
Embodiment
The anti-sound of the miniature bone conduction device of one as shown in Figure 1-2 reveals sound insulation chamber, comprise the anti-sound leakage device 1 of inner cover, strutting piece 2, the anti-sound leakage device 3 of outer cover and air barrier 4, the anti-sound leakage device 1 of described inner cover comprises base 5 and cambered surface 6, described base 5 is circular configuration, described cambered surface 6 is vertically arranged along the circumference on base 5, and the base 5 described in surrounding, described outer cover anti-sound leakage device 3 surrounds the anti-sound leakage device 1 of described inner cover, described inner cover anti-sound leakage device 1 is connected by strutting piece 2 with the upper end of the anti-sound leakage device 3 of outer cover, described inner cover anti-sound leakage device 1 forms air barrier 4 with the lower end of the anti-sound leakage device 3 of outer cover.
Described strutting piece 2 is loop configuration.
The anti-sound leakage device 1 of described inner cover is composite noise-absorbing material.
The anti-sound leakage device 1 of described inner cover is nylon.
Be bone-conduction speaker equipment sounding effect simulation schematic diagram shown in Fig. 3, in figure, 11 is bone-conduction speaker audible devices, is sound generation source, and 12 be that the anti-sound of miniature bone conduction device of the present invention is revealed every sound cavity apparatus, and 13 is that to simulate radius be the sense of hearing of 30cm.
From in Fig. 3, seismaesthesia and sound are maximum, and when revealing every sound cavity apparatus 12 through the anti-sound of miniature bone conduction device, sound is decayed; As can be seen from simulation schematic diagram, sound and seismaesthesia are when revealing every sound cavity apparatus 12 through the anti-sound of miniature bone conduction device, and sound has obvious decay.
It can also be seen that in simulation schematic diagram, revealing every sound cavity apparatus 30cm place apart from anti-sound, almost can't hear bone conduction device and vibrating sent sound in atmosphere.
In all bone-conduction speaker equipment, the shell of bone conduction device is closed, so sound source is all closed in the enclosure, the present embodiment is the leakage sound that sound-inhibiting sends at bone-conduction speaker rear, the anti-sound of miniature bone conduction device reveals sound insulation chamber to be by noise reduction material and to be compoundly designed to one, thus obviously reduces bone conduction device and to leak sound.
Structure of the present invention is simple, and being the anti-sound leakage device about preventing bone conduction earphone and other wearable device sound of osteoacusis from revealing, being mainly used in the shell of bone conduction earphone, this device adopts multilayer material, can effectively reduce the leakage sound of bone conduction device.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention, every according in technical spirit of the present invention to any simple modification, equivalent variations that above embodiment is done, all fall within protection scope of the present invention.
