Specific embodiment

Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment Described in embodiment do not represent all implementations consistent with this disclosure.On the contrary, they be only with it is such as appended The example of the consistent device and method of some aspects be described in detail in claims, the disclosure.

It is only to be not intended to be limiting the disclosure merely for for the purpose of describing particular embodiments in the term that the disclosure uses. The "an" of the singular used in disclosure and the accompanying claims book, " described " and "the" are also intended to including majority Form, unless the context clearly indicates other meaning.It is also understood that term "and/or" used herein refers to and wraps It may be combined containing one or more associated any or all of project listed.

In the related technology, the grounding point of electronic equipment is grounded by elastic slice, in antenna low-frequency range (1GHz or less) electricity The radiation field of aerial of sub- equipment is to be motivated by the end of left and right two of antenna compartmentation strip to electronic equipment complete machine, works as people Hand can seriously affect antenna field excitation when holding electronic equipment two sides, so that aerial signal be made to decay.Fig. 1 is people in the related technology Hand holds the schematic diagram of a scenario of electronic equipment, and Fig. 2 is the schematic diagram of antenna field excitation in electronic equipment in Fig. 1, and wherein Fig. 2 a is The schematic diagram of the main view direction of casting of electronic device, Fig. 2 b are the schematic diagrames of the side-looking direction of casting of electronic device.It is electric in Fig. 2 a Sub- apparatus casing 1 is the first metal shell 11 and the second metal shell 12 by the partition of antenna compartmentation strip 13；In conjunction with shown in Fig. 2 b, day The end of left and right two that line mainly passes through antenna compartmentation strip 13 carries out field excitation (direction shown in arrow in figure), meeting when manpower is held The field excitation of antenna is influenced, so that aerial signal is decayed.

Therefore, the disclosure provides a kind of electronic equipment, can reduce manpower and hold the influence for making aerial signal decay.It is described Electronic equipment can be mobile communication terminal, removable computer or tablet computer, naturally it is also possible to be other with metal shell and The electronic equipment of antenna, herein with no restrictions.The disclosure is further described below in conjunction with shown in Fig. 3.

Fig. 3 is the schematic diagram of the shell of a kind of electronic equipment shown in one exemplary embodiment of the disclosure.The electronic equipment Including metal shell 3 and antenna, antenna is set to below the metal shell 3 and is fixed on mainboard.In the present embodiment, metal shell 3 be the rear cover of electronic equipment or a part of rear cover.Metal shell 3 is divided into the first metal shell 31 and second by partition grooves 33 Metal shell 32, antenna compartmentation strip can be filled in the partition grooves 33, which is located in the gripping area of electronic equipment.It changes Yan Zhi, when electronic device design is laid out, the second metal shell 32 is located at the bottom of electronic equipment, and the first metal is located at the second metal The top of shell 32, the volume of the second metal shell 32 is less than the first metal shell 31；The problems such as considering space, signal transmitting will Antenna is set to the end of electronic equipment；Such as upper end setting WIFI antenna and Bluetooth antenna, the lower end of electronic equipment are set It sets primary antenna (such as inverse-F antenna), each antenna can be by partition grooves 33 to electronic equipment external radiation, and due to user's use habit Primary antenna is located at hand grasp area, thus signal can be made to decay.Based on this, the disclosure is arranged a conductive structure 34 and connects the first metal Shell 31 and the second metal shell 32, and the conductive structure 34 is connect with the place of returning of antenna, so that low-frequency range is by leading Electric structure 34 carries out field excitation (direction shown in arrow in figure) to electronic equipment complete machine.

As shown in Figure 3, in the electronic equipment of the disclosure field excitation of antenna be predominantly located at conductive structure 34 and its near.It leads Electric structure 34 is arranged close to the feed point 35 of antenna, thus low-frequency resonant can be formed with antenna, is formed by low-frequency resonant meeting again Field excitation is carried out to metal shell.In the present embodiment, the electromagnetic wave that antenna is formed is by conductive structure 34 by the second metal shell 32 carry out field excitation to the first metal shell 31, wherein the first metal shell 31 can be used as the complete machine of electronic equipment, antenna is to electricity Sub- equipment complete machine is motivated to export as signal.The two sides of only contacting electronic equipments shell when manpower holds electronic equipment, The position on 34 place casting of electronic device of conductive structure will not be contacted, though human contact to the position, since antenna passes through The conductive structure 34 carries out field excitation, will not make antenna low frequency signals decay.

Further, the conductive structure 34 can be integrally formed with the shell of electronic equipment, and metal also can be used The muscle position of material is connected on the shell of electronic equipment.In one embodiment, conductive structure 34 is welded on the first gold medal using muscle position Belong on shell 31 and the second metal shell 32.The first metal shell 31 and the second metal shell are directly welded at using muscle bit architecture On 32, the processing technology of implementation is simple, without changing original production technology.In another embodiment, conductive structure 34 is formed in On first metal shell 31, the free end of conductive structure 34 connects the second metal shell 32.Alternatively, conductive structure 34 is formed in On two metal shells 32, the free end of conductive structure 34 connects the first metal shell 31.Make conductive structure 34 in process of production It is formed on one in the first metal shell 31 and the second metal shell 32, is connected on another by welding manner, it is only necessary to Change the micro-structure of a metal shell, it is simple process, easily operated.In another embodiment, conductive structure 34 with First metal shell 31 and the second metal shell 32 are integrally formed.Such as it when manufacturing mobile phone metal shell, is cut using CNC technique When cutting antenna partition grooves 33, a part of metal shell is reserved without cutting and as conductive structure 34, is hardly changed original The connection of two metal shells can be realized in production technology.

Further, conductive structure 34 is set in one preset range of side apart from metal shell, metal shell Side is conductive structure 34 at the edge of the plane of metal shell.In the embodiment shown in fig. 3, conductive structure 34 is apart from metal The side distance X of shell can be 25mm to 30mm.In such distance range, antenna, which can separate antenna compartmentation strip, is Low-frequency range and medium-high frequency section, antenna cooperation tuning circuit can carry out multiband communication, improve Antenna Operation efficiency.

The foregoing is merely the preferred embodiments of the disclosure, not to limit the disclosure, all essences in the disclosure Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of disclosure protection.
