Description

The Miniaturized Communications device

[technical field]

The utility model relates to a kind of communicator, relates in particular to a kind of Miniaturized Communications device that can be applicable to portable devices such as mobile phone.

[background technology]

Fast development along with wireless telecommunications, Global Mobile Phone is more and more, people are not limited only to basic conversation to the requirement of mobile phone, more require it to have multiple amusement function and miniaturization concurrently, be easy to carry about with one, this just requires the distribution of its inner components and parts more reasonable, to reach the effect of optimizing space resources.So, under the prerequisite that guarantees electro-acoustic element superperformances such as mobile phone, it is progressively developed to extra small ultra-thin direction, be a problem demanding prompt solution.

Near-field communication (Near Field Communication, NFC) technology is a kind of emerging technology of develop rapidly recent years, propose by Sony, Philips and Nokia company, it not only can make two electronic communication devices that contain the NFC function can directly carry out the communication of short distance, can also realize multinomial functions such as audio-visual transmission, amusement search, photography are taken pictures, navigator fix, and be easy to be arranged in the electronic product, it is convenient for carrying.So can satisfy the electronic technology of most of user's requests, NFC also becomes one of requisite element of communicator.

In the communicator of prior art, the product that has the NFC function all is that portion is NFC device independent allocation space, especially a NFC coil within it, must depend on certain space and places.Consider that again speaker unit and audio power amplify chip and also all independently have communicator inside, can waste the inner space of communicator so widely, make its structural design compact inadequately, be unfavorable for that very it develops to extra small ultra-thin, portable direction.

Therefore, be necessary to provide a kind of new technical scheme to solve the problems referred to above.

[utility model content]

The technical problem that the utility model need solve is to provide a kind of microminiaturization, portable Miniaturized Communications device.

The utility model solves above-mentioned technical problem by such technical scheme:

A kind of Miniaturized Communications device, wherein, this Miniaturized Communications device comprises pedestal, with the pedestal winding and form the loam cake of spatial accommodation, the active circuit unit that is provided with phonation unit, near field communication unit in the described spatial accommodation and electrically connects with phonation unit and near field communication unit.

As a kind of improvement of the present utility model, described nearly electric field communication unit is provided with nearly electric field communication coil, and this nearly electric field communication coil is provided with lead-in wire, and described wire bonds is to the active circuit unit.

As a kind of improvement of the present utility model, described nearly electric field communication coil is formed in the electrodeposited coating of base interior.

As a kind of improvement of the present utility model, described active circuit is integrated with the power amplification chip on the unit.

As a kind of improvement of the present utility model, described active circuit unit is provided with the lead terminal of output signal.

As a kind of improvement of the present utility model, be covered with a breach on described, described lead terminal stretches out by breach and links to each other with outside mainboard.

Compared with prior art, the utlity model has following advantage: because near field communication unit, phonation unit and active circuit unit are integrated in the spatial accommodation, into a single integrated structure, can save the inner space of Miniaturized Communications device, be beneficial to it and develop to microminiaturized, portable direction.

Fig. 2 is the three-dimensional exploded view of the utility model Miniaturized Communications device.

[embodiment]

The utility model is described in further detail below in conjunction with drawings and embodiments.

See also Fig. 1 and Fig. 2, Miniaturized Communications device 10 comprises pedestal 11, forms loam cake 12, the phonation unit 13 that is positioned at spatial accommodation, active circuit unit 14 and the near field communication unit 15 of spatial accommodation 121 with pedestal 11 windings.

Pedestal 11 comprises bottom surface 110 and side 111, and phonation unit 13, active circuit unit 14 and near field communication unit 15 lay respectively on the bottom surface 110.Phonation unit 13 is provided with loud speaker 130, and this loud speaker 130 is provided with magnetic circuit system, vibrational system, and accommodates the basin frame of magnetic circuit system and vibrational system.Under the effect in magnetic circuit system magnetic field, can cause the vibration of vibrational system, thereby loud speaker 130 is sounded, realize the electroacoustic translation function.

Active circuit unit 14 is provided with wiring board 140, and this wiring board 140 is used for providing the signal of telecommunication to the inner member of Miniaturized Communications device 10.Wiring board 140 is provided with lead terminal 141 and the power amplification chip (figure does not mark) that is used for signal output.Described power amplification chip is the power amplification that is used for sound signal, and sound is transmitted better.In the present embodiment, the power amplification chip is arranged on the position near lead terminal 141, after making things convenient for lead terminal 141 to receive the signal of telecommunication of cell phone mainboard, it is inputed to the power amplification chip handle, and pass to loud speaker 130.

Near field communication unit 15 is provided with near-field communication coil 150, and this nearly electric field communication coil 150 is provided with lead-in wire (not marking among the figure), and this lead-in wire is connected with active circuit unit 14 in the mode of welding.Described nearly electric field communication coil 150 is to be made by any one or its alloy material in aluminium foil, copper, silver, gold and the plumbous material, it is reception and/or the emission that is used for being implemented in the communication process signal of communication, be operated in the 13.56MHz frequency range, in several centimetres of the transmission ranges.In the present embodiment, nearly electric field communication coil 150 is to adopt electroplating technology to combine with the pedestal 11 of Miniaturized Communications device 10, make it to be integrated on the sidewall 111 of pedestal 11, and can certainly be the electrodeposited coating that is positioned at the phonation unit outside.

Loam cake 12 is provided with a breach 120, and this breach 120 is used to accommodate the lead terminal 141 of source circuit unit 14, lead terminal 141 is stretched out by breach 120 and links to each other with outside mainboard.

To sum up, into a single integrated structure because near field communication unit, phonation unit and active circuit unit are integrated in the spatial accommodation, can save the inner space of Miniaturized Communications device, be beneficial to it and develop to microminiaturized, portable direction.
