Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. 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.

In order to better understand the present invention, the working principle of the sound generator and the camera involved in the embodiment of the present invention will be briefly described below.

The basic principle of the sounder is: when the diaphragm of the sounder vibrates, it pushes the air to move. When the frequency of the diaphragm vibration of the sounder falls within the frequency range of auditory perception of the human ear, the corresponding sound can be heard.

The basic principle of the camera is: collect external light through a set of lenses of the lens module, focus the collected light on the photosensitive component and then form an image. The fine-tuning of the front and rear positions means that the lens module needs to move back and forth.

In some embodiments of the present invention, an assembly structure is provided, as shown in FIGS. 1 to 5 , including:

magnet 10;

a coil assembly 40, the coil assembly 40 is arranged in the magnetic field formed by the magnet 10;

The coil assembly 40 is provided with a sounder diaphragm 20 and a camera lens module 30 , and the coil assembly 40 drives the sounder diaphragm 20 and the lens module 30 to move when moving in the magnetic field.

Here, the assembly structure integrates the sounder and the camera, the sounder diaphragm 20 and the camera lens module 30 share the magnet 10, the sounder diaphragm 20 and the camera lens module 30 are arranged on the coil assembly 40, and the coil assembly 40 When the magnet 10 moves in the magnetic field formed, it drives the diaphragm 20 of the sounder and the lens module 30 to move, so as to realize the sounding function of the sounder and the shooting function of the camera.

Wherein, the coil assembly 40 includes at least one coil, the sounder diaphragm 20 and the camera lens module 30 are arranged on at least one coil, and the coil is arranged in the magnetic field formed by the magnet 10. When a current passes through the coil, the coil will generate an induction. The electromotive force pushes the coil to move up or down under the action of an external magnetic field, so that the speed and amplitude of the coil movement can be controlled by controlling the direction and magnitude of the current, thereby controlling the speed and amplitude of the vibration of the sounder diaphragm 20, and the lens mode The speed and magnitude of group 30 moves.

Wherein, the sounder can be a receiver or a loudspeaker.

The assembly structure of the embodiment of the present invention can greatly reduce the space requirements of the two devices by combining the sounder and the camera into one, reduce the space occupation, and have more advantages in structure and layout than the previous independent devices; and the sounder and the camera are shared The magnet reduces the hardware cost; and the sounder and the camera do not need to keep a safe distance, and the space occupied by the two is reduced, so the size of the sounder and the camera can be larger, thereby improving the performance of the sounder and the camera.

Optionally, the assembly structure also includes:

The bracket 50 is fixedly connected with the magnet 10 , the peripheral bracket of the sounder and the peripheral bracket of the camera respectively.

At this time, the sounder, the camera and the magnet 10 can be fixed together by the bracket 50 . The bracket 50 can also fix the sounder and other non-moving parts of the camera.

Wherein, the bracket 50 is provided with leakage holes.

Here, a leakage hole is set on the bracket 50, which avoids the sounder diaphragm 20 and the camera lens module 30 forming a sealed environment in the bracket 50, which is unfavorable for the problem that the sounder diaphragm 20 and the camera lens module 30 move, ensuring Sounder and camera work properly.

Specifically, a leakage hole may be provided at the position of the support 50 corresponding to the back of the sound generator diaphragm 20 , or a leakage hole may be provided at the position of the support 50 corresponding to the back of the lens module 30 .

Optionally, the coil assembly 40 includes a first coil 41 and a second coil 42;

The sounder diaphragm 20 is arranged on the first coil 41, and the first coil 41 drives the sounder diaphragm 20 to move when moving in the magnetic field;

The lens module 30 is arranged on the second coil 42 , and the second coil 42 drives the lens module 30 to move when it moves in the magnetic field.

At this time, the sounder and the camera use independent coils respectively, but share the magnet 10 and the bracket 50, wherein the first coil 41 drives the sounder diaphragm 20 to move when moving in the magnetic field, and can realize the sounding function of the sounder. The second coil 42 When moving in the magnetic field, the lens module 30 is driven to move, and the camera shooting function can be realized.

In the embodiment of the present invention, the sounder and the camera can also share a coil, that is, the coil assembly 40 includes a coil, the sounder diaphragm 20 and the camera lens module 30 are all arranged on the coil, and the coil drives the sound when it moves in the magnetic field The diaphragm 20 and the lens module 30 move.

In the embodiment of the present invention, the sounder and the camera can be arranged in opposite directions, or the sounder and the camera can be arranged in the same direction.

Optionally, as shown in FIG. 1 , the magnet 10 is located between the sound generator diaphragm 20 and the lens module 30 .

At this time, the magnet 10 is located between the sounder diaphragm 20 and the lens module 30 , that is, the sounder diaphragm 20 and the lens module 30 are located on opposite sides of the magnet 10 , and the sounder and the camera are oppositely arranged.

However, when the sound generator and the camera head are arranged oppositely, the first coil 41 and the second coil 42 are also located on opposite sides of the magnet 10, and since there are two sets of coils, the thickness of the assembly structure will obviously increase.

In order to reduce the thickness of the assembly structure, optionally, the magnet 10 extends toward the first side of the sounder diaphragm 20 into the space surrounded by the first coil 41; the magnet 10 faces toward the lens The second side of the module 30 extends into the space surrounded by the second coil 42 .

At this time, the first side and the second side of the magnet 10 are respectively extended into the first coil 41 and the second coil 42, reducing the thickness of the common part, making the sounder diaphragm 20 and the camera lens module 30 relatively close, thereby The thickness of the assembly structure is reduced, making the assembly structure lighter and thinner, and reducing the space occupied.

For example, as shown in Figure 2, a magnet 10 with a special shape is used, and the two sides of the magnet 10 protrude outwards, respectively extending into the first coil 41 and the second coil 42, reducing the thickness of the common part, thereby reducing the assembly. The thickness of the structure.

Certainly, the shape of the magnet 10 is not limited to the shape shown in FIG. 2 , and any suitable shape of magnet can be used in the embodiment of the present invention. Specifically, the shape of the magnet can be adjusted and adapted according to the actual structural requirements, so as to better adapt to the working requirements of the sound generator and the camera.

The reverse arrangement of the sounder and the camera is more suitable for the rear camera. At this time, the rear camera and the sounder of the mobile terminal can be integrated together. The rear camera and the sounder share the magnet 10, and the magnet 10 is located on the diaphragm of the sounder. 20 and the camera lens module 30, reducing the space occupied by the rear camera and the sound generator.

When the sounder and the camera are set in opposite directions, the layout of the camera can be prioritized, and the camera can be placed according to the layout designed for the mobile terminal. Because the layout of the camera is preferred, and it is generally used in full-screen devices, the sound outlet of the sound generator will be set on the upper or top of the whole machine. At this time, after the assembly structure is installed on the whole machine, the sound generator will generally not be aligned with the sound output. mouth.

In order to ensure that the sound generated by the sound generator is exported to the correct position, optionally, the assembly structure also includes:

A sound guide channel, one end of the sound guide channel communicates with the sound output channel of the sound generator, and the other end communicates with the sound output port of the mobile terminal.

At this time, the sound output channel of the sound generator can be exported to the sound output port of the mobile terminal through the sound guide channel, so as to ensure that the sound generated by the sound generator can be exported to a correct position.

Wherein, in order to meet the requirement of back leakage when the sounder is working, a leakage hole can be provided at the position of the support 50 corresponding to the back of the sounder diaphragm 20 to ensure the normal operation of the sounder.

Optionally, the signal line of the sounder and the signal line of the camera are arranged on a flexible circuit board; the flexible circuit board is connected to the main board of the mobile terminal through a board-to-board BTB connector.

At this time, the signal line in the sounder circuit and the signal line of the camera circuit are set on the flexible circuit board FPC, and then the FPC is connected to the main board of the mobile terminal through the BTB connector, thereby protecting the circuit of the sounder and the camera, ensuring that the sounder and normal use of the camera.

The signal line of the sounder and the signal line of the camera can use the same FPC, for example, the signal line of the sounder can be set on the original FPC of the camera, and then connected to the main board through the BTB connector.

Wherein, when the sound generator and the camera are installed in opposite directions, since the assembly structure is a double-sided structure, when the assembly structure is placed on the main board of the mobile terminal, the main board can be designed to be broken for easy placement.

It should be noted that, in the assembly structure shown in FIG. 1 and FIG. 2 , the center line of the sounder diaphragm 20 and the camera lens module 30 overlap along the horizontal direction, but it is not limited thereto. The sounder diaphragm 20 and the camera lens module The centerlines of the lens modules 30 along the horizontal direction can also be staggered. For example, as shown in FIG. 3 , the sound generator diaphragm 20 and the camera lens module 30 are arranged side by side in the vertical direction.

Optionally, as shown in FIG. 4 , the lens module 30 is located between the magnet 10 and the sound generator diaphragm 20 .

At this time, the lens module 30 is located between the magnet 10 and the sounder diaphragm 20, that is, the sounder diaphragm 20 and the lens module 30 are located on the same side of the magnet 10, and the sounder and the camera are arranged in the same direction.

However, when the sounder is set in the same direction as the camera, the sounder diaphragm 20 may block the lens of the camera, thereby affecting the shooting effect. In order to ensure that the shooting effect is not affected, the embodiment of the present invention provides the following solutions:

Mode 1, the first part 21 of the sounder diaphragm 20 can be made of a transparent material; the orthographic projection of the first part 21 on the plane where the magnet 10 is located is the same as that of the lens of the lens module 30 on the magnet. The orthographic projections on the plane where 10 is located coincide.

At this time, the first part 21 where the sounder diaphragm 20 overlaps with the lens is made of a transparent material, which ensures that the camera will not be affected by the sounder diaphragm 20 when it is working, ensures the photographing effect, and is simple to implement and low in cost.

In the second manner, the sounder diaphragm 20 may be provided with an opening, and the lens of the lens module 30 is inserted into the sounder diaphragm 20 through the opening.

At this time, the lens is integrated on the sounder diaphragm 20 to ensure that the camera will not be affected by the sounder diaphragm 20 when it is working, so as to ensure the photographing effect. At the same time, the zoom capability of the camera can be enhanced through double-coil adjustment.

The way that the sounder and the camera are set in the same direction is more suitable for the front camera. At this time, the front camera and the sounder of the mobile terminal can be integrated together. The front camera and the sounder share the magnet 10, and the camera lens module 30 is located on the magnet. Between 10 and the sounder diaphragm 20, the space occupied by the front camera and the sounder is reduced.

When the sounder and the camera are set in the same direction, the layout of the camera can be prioritized, and the camera can be placed according to the layout designed for the mobile terminal. Because the layout of the camera is preferred, and it is generally used in full-screen devices, the sound outlet of the sound generator will be set on the upper or top of the whole machine. At this time, after the assembly structure is installed on the whole machine, the sound generator will generally not be aligned with the sound output. mouth.

In order to ensure that the sound generated by the sound generator is exported to the correct position, the assembly structure may also include a sound guiding channel, one end of which is connected to the sound output channel of the sound generator, and the other end is connected to the sound output port of the mobile terminal. At this time, the sound output channel of the sound generator can be exported to the sound output port of the mobile terminal through the sound guide channel, so as to ensure that the sound generated by the sound generator can be exported to a correct position.

In addition, because there is a sounder diaphragm 20 at the front of the camera lens module 30, the front of the camera lens module 30 is sealed. Position the leak hole. At the same time, in order to meet the requirement of back leakage when the sounder is working, a leakage hole can be provided at the position of the bracket 50 corresponding to the back of the sounder diaphragm 20, so as to ensure the normal operation of the sounder.

When the sounder and the camera are set in the same direction, the signal line in the sounder circuit and the signal line of the camera circuit can be set on the flexible circuit board FPC, and then the FPC is connected to the main board of the mobile terminal through the BTB connector, thereby protecting the sounder and the camera. The circuit of the camera ensures the normal use of the sounder and the camera. The signal line of the sounder and the signal line of the camera can use the same FPC, for example, the signal line of the sounder can be set on the original FPC of the camera, and then connected to the main board through the BTB connector.

Wherein, when the sounder and the camera are arranged in the same direction, due to the thicker thickness, when the assembly structure is placed on the main board of the mobile terminal, the main board can be designed to be broken for easy placement.

It should be noted that, in the assembly structure shown in FIG. 4 , the center line of the sounder diaphragm 20 and the camera lens module 30 coincide in the horizontal direction, but it is not limited thereto. The sounder diaphragm 20 and the camera lens module 30 can also be arranged in a staggered manner along the center line in the horizontal direction. For example, as shown in FIG. 5 , the sound generator diaphragm 20 and the camera lens module 30 are arranged side by side in the vertical direction.

In the embodiment of the present invention, the lens module 30 of the camera and the photosensitive element itself can adopt any existing suitable structure. In the embodiment of the present invention, the driving structure of the lens module 30 is adjusted to a similar moving coil vibration adjustment method. In this way, the sounder and the camera can share the magnet 10, and at the same time, because the magnet 10 required by the sounder is relatively large, only a few coils required by the camera can realize the function of pushing.

In the embodiment of the present invention, since the sounder and the camera share the magnet 10, and the camera is mostly square, the shape and size of the sounder need to be adjusted and adapted. When the size of the sounder is small, it can be made into a receiver. When the size is larger, it can be made into a small speaker.

The assembly structure of the embodiment of the present invention can greatly reduce the space requirements of the two devices by combining the sounder and the camera into one, reduce the space occupation, and have more advantages in structure and layout than the previous independent devices; and the sounder and the camera are shared The magnet 10 reduces the hardware cost; and the sounder and the camera do not need to keep a safe distance, and the space occupied by the two is reduced, so the size of the sounder and the camera can be larger, thereby improving the performance of the sounder and the camera.
