Description
Technical field
The utility model belongs to the transducer that a kind of signal of telecommunication is converted to acoustical signal, particularly relates to a kind of electroacoustic transducer being applied to the tow sides sounding of earphone.
Background technology
Along with the high speed development of the communication technology, audio frequency and video and each intelligent terminal, particularly smart mobile phone in recent years is universal, and the tonequality that people pursue high-quality is more enjoyed, and this proposes requirements at the higher level to the core component electroacoustic transducer of earphone.For earphone, space structure is little, needs the wearing custom taking into account people simultaneously, the size of phonation unit is general all smaller, particularly In-Ear earphone, the size of phonation unit is less, and phonation unit can not ideally to be reset the sound of the whole frequency band of low, middle and high frequency usually by size restrictions.In the supporting sound equipment of traditional multimedia, generally for the sound of whole frequency band of resetting very well, the combining form of multiple loud speaker can be adopted realize, the specific frequency band of different speaker playbacks, the acoustic constituents of such as woofer and high pitch loudspeaker just playback low frequency and HFS respectively, but in the application scenario in less space, such as earphone, particularly In-Ear Headphones, adopt the combining form of multiple unit to realize the sound of whole frequency band reset, too many space can be taken undoubtedly, affect the outward appearance of whole product and wear comfortableness.
Summary of the invention
The purpose of this utility model is to provide a kind of electroacoustic transducer that can realize tow sides sounding simultaneously, especially the voice signal of tow sides playback different frequency section can be realized, double-edged signal by radiateing after superposition, improves efficiency and the acoustical quality of electroacoustic transducer again.
The purpose of this utility model is achieved through the following technical solutions:
An electroacoustic transducer for tow sides sounding, comprises annular stent, annular pcb board and cup-shaped magnetic cup, it is characterized in that,
In the annulus through hole of support, magnetic cup is installed, sound-generating element and rear sound-generating element before the two sides of magnetic cup is separately installed with; Rear sound-generating element to be connected with reverse side protecgulum to combine by being enclosed within the reverse side magnet steel of magnetic cup cup outside, reverse side magnetic conduction sheet, reverse side voice coil loudspeaker voice coil, reverse side vibrating diaphragm successively; Front sound-generating element to be connected with front protecgulum to combine by being arranged on the front magnet steel of magnetic cup cup inside, front magnetic conduction sheet, front voice coil loudspeaker voice coil, front vibrating diaphragm successively; Pcb board, is enclosed within the outside of reverse side protecgulum, and connects reverse side voice coil loudspeaker voice coil and front voice coil loudspeaker voice coil by holding wire.
In order to obtain better technique effect, the bottom of cup of magnetic cup has through hole; Magnetic cup, between reverse side magnet steel and reverse side magnetic conduction sheet, be formed with reverse side magnetic gap; Magnetic cup, between front magnet steel and front magnetic conduction sheet, be formed with front magnetic gap; Support, between magnetic cup and reverse side magnet steel, be formed with structure air gap, and structure air gap communicates with reverse side magnetic gap.
The utility model structure is simple, utilize a magnetic cup and arrange two sound-generating element in magnetic cup both sides, decrease a magnet in sound-generating element, decrease taking up space of two sound-generating element, and further structure air gap is set between magnetic cup and support, sound-generating element, be convenient to acoustical signal that rear sound-generating element sends be transmitted to front sound-generating element by structure air gap and achieve the acoustical signal mixing sent with front sound-generating element preferably, reach the object realizing different frequency acoustical signal in an earphone, and user can not be given obvious sound difference.
Accompanying drawing explanation
Fig. 1 is the part composition schematic diagram of the utility model structure electroacoustic transducer;
Fig. 2 is the profile of the utility model structure electroacoustic transducer.
Embodiment
Contrast accompanying drawing below in conjunction with example the utility model structure is described further.
As shown in Figure 1, 2, a kind of electroacoustic transducer of tow sides sounding, comprise annular stent 1, annular pcb board 2 and cup-shaped magnetic cup 3, the magnetic cup 3 that bottom has through hole is installed, sound-generating element and rear sound-generating element before the two sides of magnetic cup 3 is separately installed with in the annulus through hole of support 1; Rear sound-generating element to be connected with reverse side protecgulum 11 to combine by being enclosed within the reverse side magnet steel 15 of magnetic cup 3 cup outside, reverse side magnetic conduction sheet 14, reverse side voice coil loudspeaker voice coil 13, reverse side vibrating diaphragm 12 successively, magnetic cup 3, is formed with reverse side magnetic gap 16 between reverse side magnet steel 15 and reverse side magnetic conduction sheet 14; Support 1, between magnetic cup 3 and reverse side magnet steel 15, be formed with structure air gap 4, and structure air gap 4 communicates with reverse side magnetic gap 16; Front sound-generating element to be connected with front protecgulum 21 to combine by being arranged on the front magnet steel 25 of magnetic cup 3 cup inside, front magnetic conduction sheet 24, front voice coil loudspeaker voice coil 23, front vibrating diaphragm 22 successively; Magnetic cup 3, between front magnet steel 25 and front magnetic conduction sheet 24, be formed with front magnetic gap 26; Pcb board 2, is enclosed within the outside of reverse side protecgulum 11, and connects reverse side voice coil loudspeaker voice coil 13 and front voice coil loudspeaker voice coil 23 by holding wire.
The utility model electroacoustic transducer, double-edged front sound-generating element and rear sound-generating element can distinguish sounding, and as optimization, front sound-generating element is different with the occurrence frequency of rear sound-generating element.
When pcb board 2 connects the signal of telecommunication, reverse side vibrating diaphragm 12 and front vibrating diaphragm 22 is excited to send acoustical signal respectively by reverse side voice coil loudspeaker voice coil 13 and front voice coil loudspeaker voice coil 23;
