Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 1 , FIG. 1 is a structural sectional view of a motor provided by an embodiment of the present invention. As shown in Figure 1, the motor consists of:

Wherein, the pronunciation assembly 1 includes an assembly with a pronunciation function, and the vibration assembly 2 includes an assembly with a vibration function, for example, a loudspeaker with a pronunciation function and a linear motor with a vibration function are placed in the housing 3 at the same time; or in the housing 3 The setup includes the sounding assembly of the coil and the diaphragm, and the vibrating assembly including the magnet and elastic components.

In this embodiment, the sounding assembly 1 and the vibrating assembly 2 are simultaneously arranged in the hollow chamber inside the casing, and the casing can protect the sounding assembly and the vibrating assembly and prevent the sounding assembly and the vibrating assembly from being damaged. Wherein, the housing 3 may be formed by a combination of one or more components, and the shape of the housing 3 may be specifically designed according to the internal space of the mobile terminal, such as a cylinder or a cuboid to improve space utilization. In addition, the sound producing component 1 and the vibrating component 2 are located in the casing, which facilitates the installation of the motor.

The above-mentioned first electrical signal can be a current signal with a current frequency close to the resonance frequency of the sounding component 1 , and when the motor receives the first electric signal, the sounding component 1 vibrates and sounds, which can improve the sounding effect. The second electrical signal can be a current signal whose current frequency is close to the resonance frequency of the vibration component 2. When the motor receives the second electrical signal, the vibration frequency of the vibration component 2 reaches the resonance frequency, which can improve the vibration effect.

In this way, the motor of the present invention can control the motor to achieve sound or vibration effects by inputting different electrical signals to the motor. The implementation method is simple and the production cost can be reduced. Since the motor of the present invention combines the sounding component and the vibrating component into one device, it is convenient to manufacture and install the motor, which can improve production efficiency and reduce production cost.

The structural form of the vibrating membrane 12 can be referred to as shown in FIG. 2 , but is not limited thereto. The coil 11 is also electrically connected to the circuit board, and when the current is input to the coil, the coil 11 vibrates, which can drive the vibrating membrane 12 to vibrate, thereby emitting sound.

For the vibration assembly 2 , one side of the elastic component 22 can be connected to the magnet 21 , and the other side of the elastic component 22 can be connected to the housing 3 . Wherein, the position of the magnet 21 can be close to the position of the coil 11 , and there is a certain gap between the position of the magnet 21 and the coil 11 .

When the coil 11 receives a first electrical signal, for example, a high-frequency current, the coil 11 generates a magnetic field, and the coil 11 drives the vibrating membrane 12 to vibrate, thereby causing the surrounding air to vibrate and generate sound. Wherein, the first electrical signal may be a current signal with a current frequency close to the resonance frequency of the vibrating membrane 12 . When the current frequency of the first electrical signal is much higher than the resonance frequency of the vibrating component 2 , when the first electrical signal is input, the vibration frequency of the vibrating membrane 12 reaches the resonant frequency to make a sound, while the vibrating component 2 vibrates weakly.

When the coil 11 receives the second electrical signal, for example, low-frequency current, the coil 11 generates a magnetic field, causing the magnet 21 to vibrate, thereby driving the elastic component 22 to vibrate, and further driving the mobile terminal to vibrate. Wherein, the second electric signal can be a current signal whose current frequency is close to the resonant frequency of the vibrating component 2, and the current frequency is quite different from the resonant frequency of the vibrating membrane 12, so that when the vibrating component 2 vibrates, the sounding component 1 does not make a sound .
