The present application does not limit the type of the antenna radiator. The length of the antenna radiator is equal to the wavelength corresponding to one working frequency band of the antenna radiator. Because the antenna radiator can normally communicate in one working frequency band or a plurality of working frequency bands, the antenna radiator can optionally select one working frequency band from the working frequency bands when the antenna radiator normally communicates, select any one frequency point in the working frequency bands, substitute the frequency point into a formula c f lambda, and calculate to obtain the wavelength. Wherein f is a frequency point and has a unit of Hertz (Hz). λ is the wavelength and the unit is meter (m). c is the speed of light, and c × m/Hz, so the present application can set the length of the antenna radiator to 1/4 of this wavelength.

The position and the form of the first connecting part are not limited in the application. The first connecting part is the main ground of the Bluetooth headset, and the grounding end of the control module, the first connecting part and the grounding point b on the FPC are grounded together. And the length of the first connecting part is 1/4 of the wavelength, and the first connecting part is used for forming a radiating body of the antenna radiating body, so that the total length of the antenna radiating body and the first grounding wire jointly meets the requirement of 1/4 wavelength, and the communication process of the Bluetooth headset is realized. The grounding point b is located at the ear handle part, and the grounding point b is away from the feeding point a by a preset distance. The preset distance may be set according to a design rule of the antenna, which is not limited in the present application. The position of the docking point b is not limited in the present application. Optionally, the grounding point b is located at the ear stem. For convenience of explanation, the grounding point b is illustrated as being located outside the feeding point a.

The second connecting portion can be arranged by adopting manufacturing processes such as in-mold injection molding, metal coating, flexible circuit board (steel sheet) or LDS (laser direct structuring), and the like, and is positioned on the lug portion. The position and the form of the second connecting part are not limited in the application. Because the grounding end of the grounding point b, the first connecting part and the grounding end of the control module are grounded, and the grounding end of the microphone is electrically connected with the grounding point b through the second connecting part, in the Bluetooth headset, the microphone and the control module can be grounded together, and the common ground interference is reduced to the minimum.

The processor, memory, storage, network devices, and/or power supply may be physically located around the display, and/or within the housing, for example. For example, the power source may include batteries coupled in parallel and held in the bottom of the electronic assembly. In another aspect, the power source may include batteries connected in parallel and sized to surround the display in the enclosure. Further, it is contemplated that components of the device, such as the processor, memory, storage, and/or networking equipment, may be mounted via one or more flexible circuits (or flex boards) so as to surround the display. The flexible circuit may be mounted directly to the display. The flexible circuit may include a malleable plastic substrate, such as a polyimide material, to facilitate placement of the flexible circuit on one or more sides and/or sides of the display. Flexible circuits may be disposed along the top and side edges of the display. In addition, the processor, memory, and storage devices may all be mounted on a flexible circuit. The processor, memory, and storage device may be electrically coupled by a flexible circuit, and further, for example, the processor may also be electrically coupled to a display. Additionally, a power source (in the form of a parallel battery) may be electrically and physically coupled to the flexible circuit (and to the processor, memory, and storage devices illustrated), as illustrated in the figures. In this way, the internal components of the electronic assembly may be disposed around the display to minimize the total surface area used by the device. It should further be noted that the flexible circuit may additionally or alternatively be physically coupled to the chassis while being electrically coupled to the display.

In summary, the present invention provides a mobile terminal with reduced lower black edge, wherein the mobile terminal comprises: a front housing; an extension structure disposed at the front case; the touch screen cover plate structure is arranged on the front shell; wherein, the extension structure can be connected with the touch screen cover plate structure. In the utility model, the purpose of increasing the glue position for dispensing on the front shell is realized by adopting the arrangement mode that the front shell is provided with the inclined top, so that the black edge area of the touch screen cover plate structure is correspondingly reduced, and the effect of effectively and easily reducing the width of the black edge at the lower end of the mobile phone is achieved.

It is to be understood that the utility model is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the utility model as defined by the appended claims.
