Fig. 2 is the cutaway view of the utility model electro-acoustic element.
[embodiment]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, for the three-dimensional exploded view of the utility model electro-acoustic element, a kind of electro-acoustic element 100 with communication function, it comprises and has the frame 3 surrounding receiving space 33 by sidewall 31, the vibrational system 2 being contained in the magnetic circuit system 1 in the receiving space of frame 3 and being immobilizated in frame 3.In other embodiments, this electro-acoustic element 100 also can be not containing the boundless frame loud speaker of frame.
Described magnetic circuit system 1 comprises the magnetic bowl 13 be contained in frame 3, be fixed on the magnet steel 11 on magnetic bowl 13 and be attached at the pole piece 12 on magnet steel 11 surface.It should be noted that, described magnetic bowl, can be bowl-shape, also can for having slab construction or being combined, as long as the element with the base plate of placement magnet portion (as magnet steel) all can be referred to as magnetic bowl by side plate that is dull and stereotyped and that extended by flat board.In the present embodiment, described magnetic bowl comprises flat board 131 and the side plate 132 from described dull and stereotyped 131 bending extensions.Described magnet steel 11 is positioned at the described central authorities of dull and stereotyped 131.Described dull and stereotyped 131 and side plate 132 be permeability magnetic material, being uniformly distributed of magnetic field can be ensured.Magnetic gap 14 is formed between described magnet steel 11 and the side plate 132 of magnetic bowl 13.In other modes selectable, described magnetic circuit system also can be the system with multiple magnet steel, being positioned at the main magnet steel of central authorities and the secondary magnet steel around main magnet steel, also can implementing as having.
The vibrating voice coil 22 that described vibrational system 2 comprises the vibrating diaphragm 21 be immobilizated in frame 3, drive vibrating diaphragm 21 to vibrate and being connected on vibrating diaphragm 21 and the listening help circle 23 be contained in the receiving space of frame 3.One end of vibrating voice coil 22 is connected on vibrating diaphragm 21, and its other end inserts in magnetic gap 14.Vibrating voice coil 22 produces electromagnetic force after being energized and vibrates along direction of vibration to drive vibrational system 2 under the effect in the magnetic field of magnetic gap 14.Listening help circle 23 is loop configuration, arranges around vibrating voice coil 22, and the inner side of listening help circle 23 is relative with the outside of vibrating voice coil 21 and be separated by and arrange.Listening help circle 23 is positioned at receiving space and is connected with vibrating diaphragm, thus decreases the volume of electro-acoustic element entirety, makes it be easy to realize microminiaturized, ultrathin.Preferably, vibrating diaphragm 21 comprise be positioned at central authorities ball top 211, around and the ring portion 212 be connected with ball top 211 and the edge part 213 be connected with ring portion 212.Edge part 213 is overlapped on the sidewall 31 of frame 3.Vibrating voice coil 22 is connected on ball top 211, and listening help circle 23 to be connected on edge part 213 and to be contained in the receiving space of frame 3.To be connected on edge part due to listening help circle and to be positioned at the downside of edge part, avoid ring portion, thus considerably reduce the impact on diaphragm oscillations, also enable listening help circle be positioned as close to protecgulum, can measuring distance be effectively reduced in product test link, improve measuring accuracy.Certainly, in other execution modes selectable, described ball top can be also other structures such as circular arc, and ball top for be separated and the structure be connected, also can be able to be structure as a whole with ring portion.
Vibrating diaphragm 21 can also be provided with the oscillating plate 24 playing the effect of reinforcement diaphragm oscillations be covered on described ball top 211.In the present embodiment, described vibrational system also comprises the protecgulum 4 be covered on vibrating diaphragm 21, and it comprises the vocal hole run through on it.
Frame 3 comprises the receiving space 33 in order to accommodate magnetic circuit system 1 surrounded by sidewall 31.Sidewall 31 comprises upper surface 311 and lower surface on the other side (non-label) and from upper surface 311 relief portion 32 that is recessed to form of surface direction downwards.Relief portion 32 is through with receiving space 33.In other examples, as in boundless frame loud speaker, this relief portion is opened in position corresponding with this listening help circle in magnetic circuit system.
During assembling, the edge part 213 of vibrating diaphragm 21 is bonded on the upper surface 311 of sidewall 31, and listening help circle 23 is connected on edge part 213, is suspended at the top of relief portion 32 and arranges near sidewall 31.When vibrational system 2 is vibrated along direction of vibration, relief portion 32 provides oscillation space for listening help circle 23.In addition, because listening help circle is sticked as far as possible on frame sidewall, effectively increase the size of listening help circle, add the swept area of listening help circle.
Described electro-acoustic element 100 is also provided with the conducting terminal 5 embedding frame 3.Described conducting terminal 5 one end and described vibrating voice coil 22 and listening help circle 23 are electrically connected, and the other end and extraneous power supply are electrically connected.In the present embodiment, voice coil loudspeaker voice coil is driven to be connected to same conducting terminal with listening help circle and to be connected with external power source by conducting terminal, in other execution modes selectable, also multiple conducting terminal can be had, drive voice coil loudspeaker voice coil to be connected with external power source respectively with listening help circle, also can implement.
Listening help circle described in electro-acoustic element of the present utility model is connected with vibrating diaphragm and is positioned at below vibrating diaphragm, thus reduces the volume of electro-acoustic element, realizes microminiaturized, ultrathin.
Above-described is only better embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite not departing from the utility model creation design; improvement can also be made, but these all belong to protection range of the present utility model.
