Abstract

The utility model relates to a bijection-module wideband mobile phone antenna of an integrated speaker, in particular to a built-in antenna which integrates the speaker on an antenna support, and belongs to the technical field of wireless communication. The bijection-module wideband mobile phone antenna of the integrated speaker comprises a support, wherein the support is made from a PC (polycarbonate) material and a platable ABS (acrylonitrile butadiene styrene) material, and a metal layer is electroplated on the surface of a region formed by the platable ABS material. A sound cavity is arranged at the left side of the support, and the sound cavity is internally provided with a sound hole. The metal layer is divided into four regions, namely ARMI, ARMII, ARMIII and ARMIV. A first gap, a second gap and a third gap are formed between the metal layer. The bijection-module wideband mobile phone antenna of the integrated speaker provided by the utility model is simple, compact and reasonable in structure, high in production efficiency, small in product volume and complete in function, complies with the current mobile phone development trend and is applicable to an ultrathin multimedia smart phone design.

Description

The double injection mould wideband antenna for mobile phone of integral speakers

Technical field

The utility model relates to a kind of double injection mould wideband antenna for mobile phone of integral speakers, specifically a kind of loud speaker is integrated in built-in aerial on the antenna holder, belongs to wireless communication technology field.

Background technology

Development along with science and technology, increasing emerging electronic product has appearred, for example panel computer, handheld device, wireless headset, wireless sound box etc., simultaneously, the products such as picture mobile phone, notebook computer are also towards ultrathin, multifunction development, the paces that electronic product updates are also more and more faster, and just the wireless connections main devices---antenna is had higher requirement to traditional for this.

The built-in aerial of existing mobile phone products generally is positioned at mobile phone top or bottom, and mobile phone speaker, motor, the first-class electronic device of shooting all are required away from antenna, prevent to disturb.These electronic devices will keep the 5mm distance at least apart from antenna, otherwise will produce significant impact to the performance of antenna, reduce greatly the efficient of antenna.But now increasing Cell Phone Design all unavoidable needs is placed near the antenna, and this just allows mobile phone producer that demand and the cell phone appearance design of antenna performance have been produced contradiction, and the performance of need to making concession satisfies appearance requirement.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of double injection mould wideband antenna for mobile phone of integral speakers is provided, when being integrated in loud speaker on the antenna holder, guarantees that serviceability is still outstanding, can satisfy client's all technical, stable outstanding during use.

According to the technical scheme that the utility model provides, the double injection mould wideband antenna for mobile phone of integral speakers comprises support, and support is made by PC (Merlon) material and electrodepositable ABS material, wherein the area surfaces electroplated metal layer of electrodepositable ABS material formation.

Described support left side is provided with the sound chamber, and sound has sender in the chamber.Described rack surface is provided with a plurality of fore-sets.

Described metal level is provided with aerial signal contact FEED and connection of antenna place GND.

Described metal level is divided into ARMI, ARMII, ARMIII and four zones of ARMIV.

Form the first slit GAP, the second slit GAP and the 3rd slit GAP between the described metal level.

Compared with the prior art the utility model has the following advantages:

The utility model is simple, compact and reasonable for structure; Production efficiency is high, and small product size is little, and is multiple functional; Comply with current mobile phone development trend, be fit to ultra-thin intelligent multimedia mobile phone design.

Embodiment

Following the utility model is further described in connection with the embodiment in the accompanying drawing:

Shown in Fig. 1 ~ 3, the utility model comprises support 1, and support 1 is made by PC material and electrodepositable ABS material, the area surfaces electroplated metal layer 2 that consists of of electrodepositable ABS material wherein, and metal level 2 is as radiating element.During the manufacturing, first by the double injection mould injection molding machine, plastic pellet with two kinds of different plating performances of PC and ABS injects support 1, then support 1 is delivered to Electroplate Factory and carry out electroless plating, plate metal level 2 at the ABS material, form the radiating element of antenna, qualified after testing after, just finished the making of antenna.

Described support 1 left side is provided with sound chamber 5, has sender 7 in the sound chamber 5, and sound chamber 5 is used for installing mobile phone speaker, and sender 7 is as the sender of mobile phone speaker.Described support 1 surface is provided with a plurality of fore-sets 6, and fore-set 6 is used for protecting sound chamber 5 and radiating element, avoids contacting with phone housing.

Described metal level 2 is provided with aerial signal contact FEED3 and connection of antenna place GND4, and the radio circuit by aerial signal contact FEED3 is connected to mobile phone links to each other with the reference ground of cell phone mainboard by connection of antenna place GND4.

Described metal level 2 is divided into ARMI8, ARMII9, ARMIII10 and four zones of ARMIV11, can adjust the parameter of low-frequency resonant by the length of adjusting ARMI8, can adjust the resonant parameter of high band by the length of adjusting ARMII9.ARMIII10 can be coupled with the loud speaker sounding, adjusts the parameter of low-frequency range, and ARMIV11 and ARMI8 are coupled to adjust the bandwidth of high band.

Form the first slit GAP12, the second slit GAP13 and the 3rd slit GAP14 between the described metal level 2.By length, the width of adjusting the first slit GAP12, can regulate the bandwidth of low-frequency range.By adjusting the second slit GAP13, can regulate the resonance location of low-frequency range.By adjusting the 3rd slit GAP14, the bandwidth that can regulate high band.

By above each position length, the bandwidth requirement of height frequency range is adjusted in the variation of width, and adapts to the electromagnetic effect of loud speaker, thereby realizes all channel antenna performance of GSM4 frequency range and WCDMA2100 frequency range.

Electrodepositable ABS material can be: strange U.S. 727, strange U.S. 757, Japanese 3001M electroplates for plastic cement for these three kinds and commonly uses.Certainly and some contains PC's, for example: Baeyer T45,777 material etc., these are done the auto parts and components plating and often select.The electric equipment products electrodepositable ABS material that contains the material of prevent fires commonly used, the total electroplating effect the best of these ABS be still: strange U.S. 727, and strange U.S. 757, these three kinds of Japanese 3001M.
