Abstract
The utility model discloses the two unit Piezoelectric anisotropy type full frequency speaker of an Artenkreis sheet, comprise moving-coil part, piezoelectric vibrator, framework and sound cover, described sound cover is fixedly mounted on the top of framework, described piezoelectric vibrator is fixed on the step of close sound cover on framework, cavity between described sound cover and piezoelectric vibrator is the ante-chamber of piezoelectric vibrator, moving-coil partial fixing is positioned on the step below piezoelectric vibrator at framework, and the cavity between described piezoelectric vibrator and moving-coil part is the back cavity of piezoelectric vibrator.The utility model, by the mode adopting piezoelectric vibrator the frequency response of moving-coil speaker to be carried out to full range compensation, makes the audio of loud speaker be increased dramatically, make user's audio experience be improved significantly, thus promote that the sales volume progress of coil-moving speaker expands.
Description
Technical field
The utility model relates to a kind of full frequency speaker, particularly the two unit Piezoelectric anisotropy type full frequency speaker of an Artenkreis sheet
Background technology
Present common coil-moving speaker just starts to decline about 8KHz frequency response, even high-end coil-moving speaker also can also start quick decline at 9.5KHz, there is now the structure (structure of the two unit of circle iron) of the coil-moving speaker adopting dynamic iron unit to compensate, realize promoting the frequency response width of loud speaker, but dynamic iron unit exists defects such as price is high, volume large (In-Ear loud speaker cannot be used for).
At present in order to realize cost effective method, reach the object of widening Hz-KHz, therefore employing cost is low, structure simple and the piezoelectric vibrator of reliability high carries out full range compensation to the frequency response of moving-coil speaker.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of two unit Piezoelectric anisotropy type full frequency speaker of defect circle sheet effectively making up the frequency response deficiency of existing moving-coil speaker high band.
The utility model in order to the technical scheme solving its technical problem and adopt is: the two unit Piezoelectric anisotropy type full frequency speaker of an Artenkreis sheet, comprise moving-coil part, piezoelectric vibrator, framework and sound cover, described sound cover is fixedly mounted on the top of framework, described piezoelectric vibrator is fixed on the step of close sound cover on framework, cavity between described sound cover and piezoelectric vibrator is the ante-chamber of piezoelectric vibrator, moving-coil partial fixing is positioned on the step below piezoelectric vibrator at framework, and the cavity between described piezoelectric vibrator and moving-coil part is the back cavity of piezoelectric vibrator.
As further improvement of the utility model, described piezoelectric vibrator is sticked to form by sheet metal and piezoelectric patches, and described sheet metal and piezoelectric patches are connected with wire.
As further improvement of the utility model, described piezoelectric vibrator is arranged on the front end of moving-coil part.
As further improvement of the utility model, described piezoelectric vibrator is bonded on the step of framework.
The beneficial effects of the utility model are: the utility model carries out the mode of full range compensation to the frequency response of moving-coil speaker by employing piezoelectric vibrator, the audio of loud speaker is increased dramatically, make user's audio experience be improved significantly, thus promote coil-moving speaker sales volume progress expand.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Indicate in figure: 1-moving-coil part; 2-piezoelectric vibrator; 3-framework; 4-sound cover; 5-sheet metal; 6-piezoelectric patches.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection range.
Fig. 1 illustrates a kind of execution mode of the two unit Piezoelectric anisotropy type full frequency speaker of the utility model one Artenkreis sheet, comprise moving-coil part 1, piezoelectric vibrator 2, framework 3 and sound cover 4, described sound cover 4 is fixedly mounted on the top of framework 3, described piezoelectric vibrator 2 is fixing on the frame 3 on the step of sound cover 4, cavity between described sound cover 4 and piezoelectric vibrator 2 is the ante-chamber of piezoelectric vibrator 2, moving-coil part 1 is fixed on the step that framework 3 is positioned at below piezoelectric vibrator 2, and the cavity between described piezoelectric vibrator 2 and moving-coil part 1 is the back cavity of piezoelectric vibrator 2.Described piezoelectric vibrator 2 is sticked to form by sheet metal 5 and piezoelectric patches 6, and described sheet metal 5 and piezoelectric patches 6 are connected with wire.Described piezoelectric vibrator 2 is arranged on the front end of moving-coil part 1.Described piezoelectric vibrator 2 is bonded on the step of framework 3.The loud speaker employing coil-moving speaker of this structure and being composited of piezoelectric vibrator, define one and cover full range sounding loudspeaker.This loud speaker has total frequency response, structure is simple, cost is low, reliability is high and make the features such as simple, is convenient to realize mass production, has the market competitiveness.
