Description
[technical field]
The utility model relates to a kind of receiver, relates in particular to a kind of receiver that is used in the portable type electronic product field.
[background technology]
In the process of mobile portable communication device fast developments such as mobile phone, as one of the necessary element of mobile portable communication device receiver, expressed more and more higher requirement.
Simultaneously, the short distance wireless communication technology is also used more and more widely, also is a kind of emerging technology of develop rapidly recent years, and this technology makes two electronic communication devices directly can carry out the communication of short distance.Come from consumer's active demand to the exchanges data between the electronic installation in the space, near field, the close range wireless communication module correspondence also becomes one of necessary element of mobile portable communication device.In order to realize the microminiaturization of each communicator, must reduce the quantity of components and parts as far as possible, make necessary components and parts have multifunction, just give birth to so have the receiver of communication function thereupon.
The receiver of correlation technique comprises the basin frame, is supported on vibrational system and magnetic circuit system on the described basin frame, described basin frame comprises the top and the back relative with described top of supporting described vibrational system, described vibrational system comprises voice coil loudspeaker voice coil, and described voice coil loudspeaker voice coil is as the voice signal incoming end.Described receiver also comprises the communication coil at the back that is arranged on described basin frame, thereby realizes radio communication function.Yet in the receiver of correlation technique, communication coil is arranged on its back, thereby makes described communication coil keeping in mind apart from bigger when signal of communication is read in reception, even can produce certain time-delay, thereby has influenced the performance of the receiver of correlation technique.
Therefore, be necessary to provide a kind of have near field communication (NFC) function with the receiver of realizing multifunction to address the above problem.
[utility model content]
The technical problem that the utility model need solve provides a kind of receiver with more excellent communication function.
According to above-mentioned technical problem, designed a kind of receiver, its objective is such realization: a kind of receiver, it comprises the basin frame, be supported on vibrating diaphragm on the described basin frame and lid is located at protecgulum on the described basin frame.Described protecgulum comprises the vocal hole that runs through on it, the lower surface of close described vibrating diaphragm and the upper surface that is oppositely arranged with described lower surface.Wherein, described receiver also comprises the communication coil of the upper surface that is arranged on described protecgulum.
Preferably, described communication coil is the upper surface engraving formation at described protecgulum.
Preferably, the upper surface of described protecgulum is provided with to the accepting groove of accommodating described communication coil of described lower surface direction depression, and described communication coil is fixed in the described accepting groove.
Preferably, the degree of depth of described accepting groove is greater than the thickness of described communication coil.
Preferably, described communication coil and the moulding of described protecgulum integrated through injection molding.
Preferably, described communication coil is the NFC coil.
Preferably, described communication coil be the annular and around described vocal hole setting.
Compare with correlation technique, the utility model receiver has the more excellent communication function of performance.
[description of drawings]
Fig. 1 is the three-dimensional structure diagram of a kind of execution mode of the utility model receiver.
Fig. 2 is the part stereochemical structure exploded view of Fig. 1.
Fig. 3 is the part stereochemical structure exploded view of the another kind of execution mode of the utility model receiver.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As Figure 1-3, a kind of receiver 10, it comprises basin frame 1, is supported on the vibrational system 2 on the basin frame 1 and is housed in the magnetic circuit system 3 in the basin frame 1 and covers the protecgulum 4 that is located on the basin frame 1, and protecgulum 4 is made for plastic material, which is provided with the vocal hole 41 that runs through on it.Vibrational system 2 comprises the vibrating diaphragm 21 that is supported on the basin frame 1 and the voice coil loudspeaker voice coil 22 that drives vibrating diaphragm 21 vibrations.Protecgulum 4 comprises near the lower surface 42 of vibrating diaphragm 21 and the upper surface 43 that is oppositely arranged with lower surface 42.Wherein, receiver 10 also comprises the communication coil 5 of the upper surface 43 that is arranged on protecgulum 4.When being used on the mobile communication equipment such as mobile phone when receiver 10, its communication coil 5 can with mobile phone in communication chip be used, thereby realize communication function.Communication coil 5 set in the utility model receiver 10 can be bluetooth line circle, Wi-Fi(Wireless Fidelity) coil, IrDA(Infrared Data Association) signal of wireless communication technology of this class of infrared data communication coil and ZigBee coil etc. reads and the coil of launching, in the present embodiment, communication coil 2 specifically is set to NFC(Near Field Communication) the near-field communication coil.
In the utility model receiver 10 communication coil 5 is arranged on the upper surface 43 of protecgulum 4, can reduces the distance that communication coil 5 reads signal of communication, improve the communication time performance, make receiver 10 have more excellent communication function.In the utility model receiver 10, communication coil 5 is made as annular and arranges around vocal hole 41.In fact, communication coil 5 also can arrange and be other shape, does not also really want to arrange around vocal hole 41, can also only be arranged on a side of vocal hole 41, and this all is feasible, but its principle is all the same.
Specify with the structure setting at the upper surface 43 of protecgulum 4 of two kinds of specific embodiments to communication coil 5 below:
First kind of execution mode joined shown in Figure 3ly, and communication coil 5 is that upper surface 43 engraving at protecgulum 4 forms.Use can be made material such as copper, the iron etc. of communication coil, be fixed on plastic material protecgulum 4 upper surface 43 and carve out communication coil 5.This engraving mode can be made the high communication coil of precision 5, and has saved the finished product communication coil 5 that will make and be fixed to protecgulum 4 steps, thus the phenomenon of defective communication coil 5 when having avoided fixedly.
Second kind of execution mode, shown in ginseng Fig. 1-2, the upper surface 43 of protecgulum 4 is provided with to the accepting groove of accommodating communication coil 5 44 of lower surface 42 directions depression, and communication coil 5 is fixed in the accepting groove 44.This structure can not increase the whole height of receiver 10 self, is conducive to the microminiaturization of receiver 10.More excellent; in the present embodiment, the degree of depth of accepting groove 44 is greater than the thickness of communication coil 5, and this structure makes 44 pairs of communication coils 5 of accepting groove play a protective role; cause the damage to communication coil 5 when having avoided because of installation receiver 10, improved receiver 10 stability.More excellent, communication coil 5 and protecgulum 4 integrated through injection molding moulding.
Compare with correlation technique, after communication coil on the utility model receiver is arranged on the protecgulum upper surface, reduced the distance that communication coil reads signal of communication, greatly degree has shortened the time of delay of reading signal of communication, improve the time performance of communication function, made the utility model receiver have more excellent communication function.
Above-described only is execution mode of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
