However, the design is not limited thereto, and in other embodiments, the coil assembly 1 may be only reused as a receiving coil or a transmitting coil in the wireless charging process on the premise that it can be used as a driving coil of the vibration motor.
It should be further noted that, when the coil assembly 1 can be used as a driving coil of a vibration motor and a transmitting coil used for a wireless charging process, a low-frequency alternating-current power supply circuit and a high-frequency alternating-current power supply circuit which are connected in parallel can be generally arranged in the electronic terminal, and the coil assembly 1 is selected to be connected with one of the low-frequency alternating-current power supply circuit and the high-frequency alternating-current power supply circuit through a switch device, specifically, when the coil assembly 1 is connected with the low-frequency alternating-current power supply circuit through the switch device, the coil assembly 1 is supplied with low-frequency alternating current; and when the coil assembly 1 is connected with a high-frequency alternating current power supply circuit through a switching device, the coil assembly 1 is supplied with high-frequency alternating current. However, the design is not limited thereto, and in other embodiments, the electronic terminal may also be provided with a fast transient power supply having independent high-frequency and low-frequency path signals to meet the requirement that the coil assembly 1 inputs low-frequency alternating current and high-frequency alternating current respectively corresponding to different functions.
In the technical scheme of the invention, the coil component 1 is used as a driving coil of a vibration motor and is also used as a receiving coil and/or a transmitting coil in a wireless charging process, namely, only one coil component 1 is needed for realizing vibration feedback and wireless charging, so that the electronic terminal only needs to be provided with an installation structure for the coil component 1, the structure of the electronic terminal can be simplified, the assembly of the electronic terminal is simpler, and the assembly precision is favorably improved; in addition, only one coil assembly 1 is needed for realizing vibration feedback and wireless charging, so that one (even two) coil assemblies 1 can be saved, the cost of the electronic terminal is reduced, the installation space of one (even two) coil assemblies 1 can be saved, the size required by the electronic terminal can be reduced, and the miniaturization of the electronic terminal is facilitated.

It can be understood that the iron core 12 and the coil 11 form an electromagnet structure, which can generate a stronger magnetic field, and is beneficial to better driving the vibrator 4 to generate vibration.
Further, the vibrator 4 includes two magnets 41, and the coil block 1 is disposed between the two magnets 41. It will be appreciated that the coil assembly 1, in cooperation with the two magnets 41, can improve the electrical efficiency of vibration. In this embodiment, one magnet 41 is connected to one end of the iron core 12 through one elastic connection member 5, and the other magnet 41 is connected to the other end of the iron core 12 through the other elastic connection member 5. Without loss of generality, the magnetizing directions of both magnets 41 face the iron core 12.
In this embodiment, optionally, a mounting cavity is disposed in the housing, and two ends of the iron core 12 are respectively and fixedly disposed on two opposite cavity walls of the mounting cavity. Of course, the cavity wall is usually provided with an avoiding hole corresponding to the elastic connector 5, so that the elastic connector 5 can be installed through the avoiding hole to connect with the magnet 41. However, the present design is not limited thereto, and in other embodiments, the electronic terminal may further include a bridge bracket, one end of which is fixedly connected to the housing, and the other end of which is fixedly connected to the iron core 12.

In this embodiment, by additionally providing the connection pad 42, the elastic sheet 51 is connected to the connection pad 42, and the connection pad 42 is connected to the magnet 41, so that the elastic sheet 51 is indirectly connected to the magnet 41.
In this embodiment, optionally, the elastic sheet 51 is welded to the connection pad 42; the welding mode can provide strong bonding force, and the connection is more reliable. Further alternatively, the connection pad 42 is bonded to the magnet 41; it can be understood that the bonding surface between the connection pad 42 and the magnet 41 can be larger than that between the elastic sheet 51 and the magnet 41, so as to ensure that the bonding force is larger, and thus the connection reliability is ensured.
It should be noted that, in the embodiment shown in fig. 1, the elastic connecting member 5 is configured as an elastic sheet 51. However, the design is not limited thereto, and in other embodiments, the elastic connecting element 5 may also be configured as a spring.

Further alternatively, the elastomer 52 may be, but is not limited to, be provided as a ring that is injection molded or adhesively secured to the core 12. Alternatively, bridge 53 may be a rigid member, such as but not limited to a steel sheet, or may be a member having some elasticity.
Further, the vibrator 4 further includes a mass (not shown) fixedly connected to the magnet 41. It can be understood that the additional arrangement of the mass block is beneficial to improving the vibration feedback effect of the electronic terminal. Of course, in other embodiments, the mass may not be added if the mass of the magnet 41 itself is already capable of generating effective vibration. In this embodiment, optionally, the mass block is fixed to the magnet 41 by bonding, which is easy to implement and reliable in connection; however, the design is not limited to this, in other embodiments, the mass block may be molded integrally with the magnet 41, the injection molding process is favorable for realizing batch production of products, and can improve production efficiency, and in addition, the magnet 41 and the mass block molded integrally have higher reliability of combination therebetween.
