Some existing mobile terminals (such as mobile phones and tablet computers) that can make calls and take pictures are generally equipped with a handset module and a camera module, and the front of the mobile terminal corresponds to the handset module and the camera module, respectively. A functional hole (ie, the earpiece hole and the light-transmitting hole) is provided. The earpiece hole is used to transmit the sound generated by the earpiece module. When the user is close to the earpiece hole, the sound can be heard.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

According to one aspect of the embodiments of the present invention, a combination device of an earpiece and a camera (hereinafter referred to as a combination device) is provided, which is applied to a mobile terminal having an earpiece function and a camera function, and the mobile terminal includes but is not limited to a mobile phone and a tablet computer. , laptops, PDAs, and wearables.

As shown in FIG. 1 , the combined device at least includes: an annular earpiece diaphragm 101 , a toroidal coil 102 , a magnet 103 (such as a permanent magnet 1 ), a lens module 104 and a switch 106 .

Among them, the earpiece diaphragm 101 plays a role in producing sound by vibrating, and is arranged on the display screen cover 114 of the mobile terminal, so that the user can listen to the sound. The membrane 101 is disposed in the through hole 109 as shown in FIG. 5 .

The toroidal coil 102 is correspondingly disposed below the earpiece diaphragm 101 , and is connected to a power-on terminal 105 for electrical connection of the audio circuit 107 or the camera motor drive circuit 108 (hereinafter referred to as the motor drive circuit 108 ).

Wherein, the lens module 104 is used for collecting external images, is located in the central hole of the toroidal coil 102 , and is fixedly connected to the toroidal coil 102 . In the embodiment of the present invention, the lens module 104 is disposed opposite to the hole in the middle of the earpiece diaphragm 101 , so that the lens module 104 can collect external images through the hole in the middle of the earpiece diaphragm 101 .

The magnets 103 are arranged around the toroidal coil 102 to provide a magnetic field environment, and a magnetic field force in a certain direction can be generated when the coil is energized. Specifically, when the coil is energized, the magnetic field generated by the coil changes, which in turn changes the magnetic force between the magnet 103 and the coil, thereby changing the distance between the magnet 103 and the coil.

Wherein, the switch 106 is not only electrically connected to the power-on terminal 105 on the toroidal coil 102, but also electrically connected to the audio circuit 107 or the motor driving circuit 108, for electrically connecting the toroidal coil 102 to the audio circuit 107 or to the motor driving circuit 108 connect.

The combined device provided by the embodiment of the present invention can realize both the earpiece function and the camera function, and its working principle is as follows:

When the combined device works in the earpiece working mode, the switch 106 conducts the power-on terminal 105 and the audio circuit 107 to electrically connect the loop coil 102 and the audio circuit 107 . Wherein, in the earpiece working mode, the toroidal coil 102 collides with the earpiece diaphragm 101, the toroidal coil 102 receives the audio signal of the audio circuit 107, and drives the earpiece diaphragm 101 to emit sound according to the audio signal, that is, the audio signal drives the toroidal coil 102 moves in a small amplitude, and the ring coil 102 which moves in a small amplitude drives the ring diaphragm to vibrate, so that the ring diaphragm emits sound, and different currents produce different vibrations, so that the ring diaphragm emits different sounds. It should be noted that although the toroidal coil 102 and the earpiece diaphragm 101 are not fixedly connected together, the vibration between the toroidal coil 102 and the earpiece diaphragm 101 is only a small-amplitude vibration, which is very small. Therefore, it is only necessary to satisfy the The toroidal coil 102 is in contact with the earpiece diaphragm 101 , so that the continuous contact between the toroidal coil 102 and the earpiece diaphragm 101 can be ensured.

When the combination device works in the camera working mode, the switch 106 conducts the power-on terminal 105 and the motor driving circuit 108 to electrically connect the toroidal coil 102 and the motor driving circuit 108 . Wherein, in the working mode of the camera, the toroidal coil 102 is separated from the earpiece diaphragm 101, and the toroidal coil 102 receives the focus driving signal from the motor drive circuit 108, and drives the ring coil 102 to move closer to the display screen cover according to the focus driving signal. The plate 114 moves in the direction away from the display screen cover 114 (that is, in the direction close to the earpiece diaphragm 101 or away from the earpiece diaphragm 101 ). , the lens module 104 will also move toward the direction close to the display screen cover 114 or away from the display screen cover 114 to achieve focusing. It should be noted that, in order to avoid contact between the ring coil 102 and the earpiece diaphragm 101 during the focusing process, the initial focusing position of the lens module 104 is designed as follows: the ring coil 102 and the earpiece diaphragm 101 are separated by a first preset distance, and The closest focusing distance of the lens module 104 (ie, the maximum focusing distance in the direction close to the display screen cover 114 ) does not exceed the first preset distance, and the first preset distance can be designed according to the focusing requirements of the lens module 104 .

In the embodiment of the present invention, the earpiece structure and the camera structure are assembled together to form the combined device in the embodiment of the present invention. The combined device can realize both the earpiece function and the camera function, which is different from the earpiece structure in the prior art and the camera structure. The camera structure is arranged separately, the combination device can reduce the occupation of the internal space of the mobile terminal. At the same time, since the earpiece diaphragm 101 and the ring coil 102 are both annular, the lens module 104 can pass the ring coil 102 and the earpiece diaphragm 101. The hole in the middle captures images. Therefore, only one functional hole needs to be opened on the display cover 114 to meet the usage requirements of the earpiece and the camera, which reduces the number of openings on the display cover 114 and is more conducive to full-screen display. development of.

Further, in the embodiment of the present invention, in order to ensure that the toroidal coil 102 can fully conflict with the earpiece diaphragm 101 in the earpiece working mode, the height of the end face of the lens module 104 facing the earpiece diaphragm 101 is smaller than that of the toroidal coil 102 . The height of the end face facing the earpiece diaphragm 101 means that the lens module 104 is located in the central hole of the toroidal coil 102 , and the end face of the lens module 104 facing the earpiece diaphragm 101 is not exposed outside the central hole.

Further, in the embodiment of the present invention, for the initial state of the combined device (ie, the non-energized state), the annular coil 102 and the earpiece diaphragm 101 may be designed to conflict with each other, or the annular coil 102 and the earpiece diaphragm 101 may be designed to be separated by a second interval. The preset distance, wherein the second preset distance is greater than, equal to or smaller than the first preset distance, and the specific situation can be designed according to actual needs.

In the embodiment of the present invention, the initial state of the combined device is preferably: the toroidal coil 102 is in conflict with the earpiece diaphragm 101 , so that when the earpiece on the mobile terminal is started to work, the toroidal coil 102 can directly respond to the audio signal of the audio circuit 107 , drive the earpiece diaphragm 101 to vibrate, without first controlling the ring coil 102 to conflict with the earpiece diaphragm 101, and then the earpiece sounds, reducing the time delay. Of course, the initial state of the combination device can also be selected as: the ring coil 102 and the earpiece diaphragm 101 are separated by a first preset distance, so that when the camera is started to work, the focus can be directly performed according to the focus drive signal of the motor drive circuit 108, and It is not necessary to firstly control the annular coil 102 to drive the lens module 104 to move to the initial focusing position of the lens module 104, so as to achieve fast focusing and reduce time delay. It can be understood that the initial state of the combined device can also be selected as: the loop coil 102 is in a compromise position between the initial focus position of the earpiece diaphragm 101 and the lens module 104, and the specific situation can be designed according to actual needs.

Wherein, when the initial state of the combination device (ie, the power-off state) is: when the loop coil 102 is in conflict with the earpiece diaphragm 101, the loop coil 102 receives the focus drive signal of the motor drive circuit 108, and drives the lens according to the focus drive signal. Before the module 104 moves toward or away from the display screen cover 114 for focusing, the circuit control method further includes:

The loop coil 102 receives the first initial drive signal from the motor drive circuit 108 , and moves a first preset distance away from the display screen cover 114 according to the first initial drive signal to form the initial focus position of the lens module 104 .

That is, when the camera is started to work, the motor drive circuit 108 will first give a certain current (ie, the first initial drive signal) to the loop coil 102, and pull the loop coil 102 away from the earpiece diaphragm 101. When there is a first preset distance, the toroidal coil 102 is stopped from being pulled, and the current position is recorded as the initial focus position of the lens module 104 . After that, the motor driving circuit 108 sends a focus driving signal to the toroidal coil 102 to control the toroidal coil 102 to drive the lens module 104 to move in a relatively large amount to achieve focusing.

Further, when the initial state of the combination device is: when there is a second preset distance between the loop coil 102 and the earpiece diaphragm 101, the loop coil 102 receives the focus drive signal of the motor drive circuit 108, and drives the lens according to the focus drive signal. Before the module 104 moves toward or away from the display screen cover 114 for focusing, the circuit control method further includes:

The loop coil 102 receives the second initial drive signal from the motor drive circuit 108 , and moves a third preset distance away from or close to the display screen cover 114 according to the second initial drive signal to form the initial focus position of the lens module 104 .

That is, when the camera is started to work, the motor driving circuit 108 will first give a certain current (ie, the second initial driving signal) to the loop coil 102, so that the loop coil 102 drives the lens module 104 to move away from or close to the display screen cover 114. When the ring coil 102 and the earpiece diaphragm 101 are separated by the first preset distance, the movement of the ring coil 102 is stopped, and the current position is recorded as the initial focus position of the lens module 104 . After that, the motor driving circuit 108 sends a focus driving signal to the toroidal coil 102 to control the toroidal coil 102 to drive the lens module 104 to move in a relatively large amount to achieve focusing.

Wherein, if the second preset distance is greater than the first preset distance, the loop coil 102 is controlled to drive the lens module 104 to move toward the direction close to the display screen cover 114; if the second preset distance is less than the first preset distance, then The loop coil 102 is controlled to drive the lens module 104 to move away from the display screen cover 114 ; if the second preset distance is equal to the first preset distance, the loop coil 102 remains stationary.

Among them, in order to ensure the user's experience, in the embodiment of the present invention, when the lens module 104 is in the initial focus position, the display screen of the mobile terminal is controlled to display the image collected by the lens module 104, so as to prevent the loop coil 102 from driving the lens module When the group 104 is in the initial focus position, the image captured by the camera is displayed on the display screen, and the display screen is unstable.

Wherein, when the initial state of the combined device is: when there is a second preset distance between the ring coil 102 and the earpiece diaphragm 101, the toroidal coil 102 receives the audio signal of the audio circuit 107, and drives the earpiece diaphragm 101 to vibrate according to the audio signal Before sounding, the circuit control method further includes:

The loop coil 102 receives the third initial drive signal from the audio circuit 107 , and moves toward the direction close to the earpiece diaphragm 101 according to the third initial drive signal, colliding with the earpiece diaphragm 101 .

That is, when the earpiece is started to work, the audio circuit 107 will first give a certain current (ie, the third initial driving signal) to the loop coil 102, so that the loop coil 102 moves in the direction close to the display screen cover 114, so that the loop coil 102 is connected to the earpiece. The diaphragm 101 collides with each other. After that, the audio circuit 107 sends an audio signal to the toroidal coil 102 to control the toroidal coil 102 to drive the earpiece diaphragm 101 to vibrate, so as to produce sound.

Further, as shown in FIG. 1 , the lens module 104 includes: a carrier 1041 fixedly connected to the toroidal coil 102 and a lens 1042 disposed on the carrier 1041 , that is, the lens 1042 is fixedly connected to the toroidal coil 102 through the carrier 1041 , Thus, the toroidal coil 102 drives the lens 1042 to move toward or away from the display screen cover 114 .

Further, as shown in FIG. 2 , the combined device further includes: a first elastic piece 111 and/or a second elastic piece 112 . The first elastic piece 111 is disposed on the side of the lens module 104 facing the earpiece diaphragm 101 , and the second elastic piece 112 is disposed on the side of the lens module 104 away from the earpiece diaphragm 101 . The specific structural shapes of the first elastic piece 111 and the second elastic piece 112 can be selected according to actual needs, which are not limited in the embodiment of the present invention.

Among them, the first elastic piece 111 and the second elastic piece 112 can play the role of balancing the electromagnetic force to adjust the moving position of the lens module 104 to achieve the micro-distance adjustment of the lens 1042, adjust the focus plane, and achieve the purpose of clear image. For example, when two shrapnel are installed, when the lens module 104 moves toward the direction close to the display screen cover 114, the first shrapnel 111 can generate a force on the lens module 104 opposite to the movement direction of the lens module 104, The second shrapnel 112 can also generate a force on the lens module 104 opposite to the moving direction of the lens module 104 , and the electromagnetic force is balanced by the sum of the acting forces of the first shrapnel 111 and the second shrapnel 112 to avoid excessive movement of the lens module 104 Moving toward the direction close to the display screen cover 114 causes the toroidal coil 102 to collide with the earpiece diaphragm 101 . Similarly, when the lens module 104 moves away from the display screen cover 114 , the first elastic piece 111 can exert a force on the lens module 104 opposite to the moving direction of the lens module 104 , and the second elastic piece 112 also A force opposite to the moving direction of the lens module 104 can be generated on the lens module 104 to balance the electromagnetic force and prevent the lens module 104 from moving too far away from the display screen cover 114 . Of course, it can be understood that the direction of the force of the first elastic piece 111 on the lens module 104 and the direction of the force of the second elastic piece 112 on the lens module 104 are not necessarily the same. The status of compression is determined. And which shrapnel to set in the combined device can also be selected according to actual needs.

Wherein, in the embodiment of the present invention, the first elastic piece 111 and/or the second elastic piece 112 can also be used to better control the conflict between the toroidal coil 102 and the earpiece diaphragm 101. For example, in the initial state of the combined device, in the Under the action of the first elastic piece 111 and/or the second elastic piece 112, the toroidal coil 102 and the earpiece diaphragm 101 can be better kept in a state of conflict, or in the earpiece working mode, the first elastic piece 111 and/or the first elastic piece 111 and/ Or under the action of the second elastic piece 112, the continuous conflict between the toroidal coil 102 and the earpiece diaphragm 101 can be better controlled.

Wherein, the combination device further includes: a casing covering the lens module 104, the casing plays a protective role for the lens module 104, and at the same time it also has the function of conducting magnetism, so as to improve the effective use of the magnet 103 and prevent the Magnetic flux leakage. Wherein, a lens through hole is formed on the casing, which corresponds to the lens 1042 in the lens module 104, so as not to affect the lens 1042 to collect external images.

Wherein, as shown in FIG. 2 , the combined device further includes: a bracket 113 that plays a supporting role. The bracket 113 can carry other structures in the combined device, such as the magnet 103 , the toroidal coil 102 , the lens module 104 and the like.

Specifically, the first elastic piece 111 is disposed between the lens module 104 and the housing. The first elastic piece 111 can be fixedly connected to the lens module 104 or the housing, and can also be connected to the lens module 104 and the housing, respectively. Shell connection, the specific situation, can be selected according to actual needs. In the embodiment of the present invention, it is preferable that the first elastic piece 111 is fixedly connected to the housing, so that when the lens module 104 moves up and down, it is not necessary to drive the first elastic piece 111 to move all the time, thereby reducing power consumption.

Specifically, the second elastic piece 112 is disposed between the lens module 104 and the bracket 113. The second elastic piece 112 can be fixedly connected with the lens module 104, or can be fixedly connected with the bracket 113, and can also be connected with the lens module 104 and the bracket 113, respectively. The bracket 113 is connected, and the specific situation can be selected according to actual needs. In the embodiment of the present invention, it is preferable that the first elastic piece 111 is fixedly connected with the bracket 113, so that when the lens module 104 moves up and down, it is not necessary to drive the second elastic piece 112 to move all the time, thereby reducing power consumption.

Further, in the embodiment of the present invention, the ring-shaped earpiece diaphragm 101 may be integrally formed; it may also be composed of two semi-ring diaphragms 1011, as shown in FIG. 3, specifically: the earpiece diaphragm 101 includes: two Half-ring diaphragm 1011, two semi-ring diaphragms 1011 are connected together by connecting glass 1012.
