[0018] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used in the specification is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0019] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, a smartphone capable of receiving television signals includes a phone frame 1 and a phone middle frame 2. A circuit board is fixedly installed inside the phone middle frame 2. A battery 3 and a screen 4 are also provided on the phone middle frame 2. The battery 3 and the screen 4 are electrically connected to the circuit board. The battery 3 is used to power the smartphone, and the screen 4 is used to display information for the user to view.

[0022] The phone frame 1 is fitted onto the outer periphery of the phone mid-frame 2, and the phone frame 1 and the phone mid-frame 2 are fixedly connected by screws. The phone frame 1 has an installation notch, on which a metal antenna 5 is installed. The metal antenna 5 can be used to receive wireless TV signals. The metal antenna 5 is fixedly connected to the phone mid-frame 2, and both ends of the metal antenna 5 are connected to the phone frame 1. The metal antenna 5 is electrically connected to the circuit board. The metal antenna 5 can receive wireless TV signals and transmit them to the circuit board. The circuit on the circuit board processes the wireless TV signals and displays them on the screen 4, so that the smartphone can directly watch live TV without the need for the network, which can reduce the user's usage cost.

[0023] Specifically, the circuit board includes an RF receiving module, a signal processing module, an intermediate frequency (IF) demodulation module, and a transmission module. When using this smartphone to play live TV, the RF receiving module receives the DTMB signal (low-frequency signal) through the metal antenna 5. The signal processing module then filters and amplifies the signal before down-converting it to the IF frequency. The IF signal enters the IF demodulation module, where it undergoes demodulation and channel decoding to obtain a transport stream (TS stream) containing audio and video data. The TS stream is transmitted to the mobile phone system via the transmission module, where an app decodes and plays it, enabling the viewing of live TV. In other embodiments, the processing of the signal received by the metal antenna 5 can be done in other ways, as long as it ensures that the live TV can be viewed on the screen 4.

[0024] The smartphone features an installation notch on the phone frame 1 to accommodate the metal antenna 5. This design avoids excessive structural clutter and simplifies the overall mechanical structure compared to a telescopic antenna, enhancing the phone's aesthetics and improving user experience.

[0025] In this embodiment, the mobile phone frame 1 is made of plastic material, and the metal antenna 5 is integrally injection molded with the mobile phone frame 1 using a plastic-encapsulated metal process. By integrally molding the mobile phone frame 1 and the metal antenna 5, the mobile phone frame 1 and the metal antenna 5 become a single part, which facilitates assembly and further enhances the aesthetics of the smartphone.

[0026] In this embodiment, the circuit board includes a first circuit board 6 and a second circuit board 7. The first circuit board 6 and the second circuit board 7 are stacked and disposed within the mobile phone frame 2. The first circuit board 6 and the second circuit board 7 are electrically connected, and the metal antenna 5 is electrically connected to the first circuit board 6. By setting two circuit boards, the volume of each circuit board can be reduced, thereby reducing the overall size of the smartphone, making it easier to use, and also improving the aesthetics of the phone.

[0027] To enable the metal antenna 5 to connect to the first circuit board 6, a first protrusion 51 and a second protrusion 52 are provided on the metal antenna 5, and a first elastic contact 61 and a second elastic contact 62 are provided on the first circuit board 6. The first elastic contact 61 abuts against the first protrusion 51, and the second elastic contact 62 abuts against the second protrusion 52. Through the contact between the two protrusions and the two elastic contacts, the metal antenna 5 can be electrically connected to the first circuit board 6, so that the television signal received by the metal antenna 5 can be transmitted to the first circuit board 6. In other embodiments, the metal antenna 5 and the first circuit board 6 can also be connected by other methods that can achieve electrical conduction, such as soldering or wire connection.

[0028] In this embodiment, a limiting groove 21 is provided inside the mobile phone frame 2. The limiting groove 21 is adapted to the size of the metal antenna 5. One side of the metal antenna 5 is inserted into the limiting groove 21, and the metal antenna 5 is fixedly engaged with the limiting groove 21. By providing a limiting groove 21 inside the mobile phone frame 2, the metal antenna 5 can be fixedly engaged with the mobile phone frame 2, preventing the metal antenna 5 from shifting during use and improving stability.

[0029] To further enhance the structural stability of the smartphone, multiple snap-fit ​​slots 22 are provided within the limiting groove 21. Snap-fit ​​blocks 53 are respectively provided at corresponding positions on the metal antenna 5 corresponding to the snap-fit ​​slots 22, and the snap-fit ​​blocks 53 are snapped into and fixed to the corresponding snap-fit ​​slots 22. During assembly, the snap-fit ​​blocks 53 on the metal antenna 5 are aligned with the snap-fit ​​slots 22 within the limiting groove 21, and then the metal antenna 5 is snapped into the limiting groove 21. The cooperation between the snap-fit ​​blocks 53 and the snap-fit ​​slots 22 allows the metal antenna 5 to be snapped into and fixed to the phone's mid-frame 2.

[0030] In this embodiment, there are 5 snap-fit ​​blocks 53 and 5 snap-fit ​​slots 22, and the two are set in a one-to-one correspondence. In other embodiments, the number of snap-fit ​​blocks 53 and snap-fit ​​slots 22 can be any other number, as long as it is ensured that the two are set in a one-to-one correspondence.

[0031] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
