Based on the above, the embodiment of the application provides an antenna module applicable to the electronic product to solve the above problems. In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings.
The terminology used in the following examples is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless expressly specified otherwise.
For example, referring to fig. 2a, the structure of the antenna module provided by the present application may include a circuit board 1, a flexible antenna 2, a ferromagnetic block 31 and a first magnetic member 32, where the ferromagnetic block 31 and the first magnetic member 32 cooperate to electrically connect the circuit board 1 and the flexible antenna 2. Since the antenna module is applied to an electronic product, its structure and function are also attached to the electronic product, and therefore, a part of the structure of the electronic product (e.g. the back cover 10 of the electronic product) is also introduced.
The circuit board 1 carries radio frequency signals of the antenna module, which can be a circuit board of an electronic product or can be a part of a circuit board of the electronic product, and when the antenna module is applied to other terminals, the circuit board 1 can be a part of circuit control hardware of the terminal or electrically connected with the circuit control hardware. An electrical connection portion is disposed on the circuit board 1 and is used for being electrically connected with the flexible antenna 2, so as to conduct signals received by the flexible antenna 2 to the circuit board 1 or conduct signals sent by the circuit board 1 to the flexible antenna 2 to radiate into space. The flexible antenna 2 has an antenna section 21 and a connection section 22, the antenna section 21 being fixed to the inside of the rear cover 10 of the electronic product by means of a back adhesive, it being understood that the inside of the rear cover 10 herein is shown in relation to the structure of the electronic product, the portion of the rear cover 10 which, in use, is outside the overall structure of the electronic product corresponding to the outside of the rear cover 10 and the portion which is inside the overall structure of the electronic product corresponding to the inside of the rear cover 10. In order to make contact with the electrical connection portion on the circuit board 1 to achieve electrical connection, the connection section 22 has a metal exposure area a, and when the metal exposure area a does not form a ring shape around the circumference of the connection section 22, the metal exposure area a is located at a side of the connection section 22 facing the circuit board 1.

The first magnetic member 32 and the ferromagnetic block 31 generate magnetic attraction to ensure the contact stability between the exposed metal area a and the electrical connection portion.

When the flexible antenna 2 is close to the circuit board 1, the first magnetic element 32 will generate a magnetic attraction effect with the second magnetic element 33, so as to press the flexible antenna 2 onto the ferromagnetic sheet 12, so that the metal exposed area a on the connection section 22 is in close contact with the surface of the ferromagnetic sheet 12 (contact point P), as shown in fig. 8b, which is equivalent to close contact between the metal exposed area a and the electrical connection portion, so that the flexible antenna 2 is electrically connected with the circuit board 1, and a function of feeding radio frequency signals from the circuit board 1 to the flexible antenna 2 or a function of feeding radio frequency signals from the flexible antenna 2 to the circuit board 1 are achieved.
