Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

According to an aspect of the embodiments of the present invention, there is provided a combined device of an earpiece and a camera (hereinafter, referred to as a combined device) applied to a mobile terminal having an earpiece function and a camera function, where the mobile terminal includes, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a palm computer, a wearable device, and the like.

As shown in fig. 1, the combination device at least comprises: an annular earphone diaphragm 101, an annular coil 102, a magnet 103 (such as a permanent magnet 1), a lens module 104 and a switch 106.

Wherein, earphone vibrating diaphragm 101 plays the vocal function through the vibration, and it sets up on mobile terminal's display screen apron 114 to the user carries out the listening of sound, specifically is: a through hole 109 is formed in the display cover 114, and the earphone diaphragm 101 is disposed in the through hole 109, as shown in fig. 5.

The loop coil 102 is correspondingly disposed below the earphone diaphragm 101, and is connected with an energizing terminal 105 for electrically connecting an audio circuit 107 or a camera motor driving circuit 108 (hereinafter referred to as a motor driving circuit 108).

The lens module 104 is used for acquiring an external image, is located in a central hole of the annular coil 102, and is fixedly connected with the annular coil 102. In the embodiment of the present invention, the lens module 104 is disposed opposite to the hole in the middle of the receiver diaphragm 101, so that the lens module 104 can collect an external image through the hole in the middle of the receiver diaphragm 101.

The magnet 103 is disposed around the annular coil 102 and is configured to provide a magnetic field environment, so that when the coil is powered on, a magnetic field force in a certain direction can be generated. Specifically, when the coil is energized, the magnetic field generated by the coil changes, and further the magnetic force between the magnet 103 and the coil changes, so that the distance between the magnet 103 and the coil changes.

The changeover switch 106 is electrically connected not only to the energizing terminal 105 of the loop coil 102 but also to the audio circuit 107 or the motor drive circuit 108, and electrically connects the loop coil 102 to the audio circuit 107 or the motor drive circuit 108.

The combined device provided by the embodiment of the invention can realize the functions of a receiver and a camera, and the working principle is as follows:

when the combination device operates in the earpiece mode, the switch 106 connects the power-on terminal 105 and the audio circuit 107, and electrically connects the loop coil 102 and the audio circuit 107. When the receiver is in the working mode, the annular coil 102 is abutted to the receiver diaphragm 101, the annular coil 102 receives an audio signal of the audio circuit 107, the receiver diaphragm 101 is driven to sound according to the audio signal, namely the audio signal drives the annular coil 102 to move in a small amplitude, the annular coil 102 moving in a small amplitude drives the annular diaphragm to vibrate, the annular diaphragm is made to sound, different currents generate different vibrations, and the annular diaphragm is made to send different sounds. It should be noted that, although the annular coil 102 and the earphone diaphragm 101 are not fixedly connected together, because the vibration between the annular coil 102 and the earphone diaphragm 101 is only a small amplitude vibration, which is very small, it is only necessary to satisfy that the annular coil 102 is in contact with the earphone diaphragm 101, and thus the continuous contact between the annular coil 102 and the earphone diaphragm 101 can be ensured.

When the combination device operates in the camera operation mode, the changeover switch 106 turns on the energizing terminal 105 and the motor drive circuit 108, and electrically connects the toroidal coil 102 and the motor drive circuit 108. When the camera is in the working mode, the loop coil 102 is separated from the earpiece diaphragm 101, the loop coil 102 receives a focusing driving signal of the motor driving circuit 108, and according to the focusing driving signal, the loop coil 102 is driven to move towards a direction close to the display screen cover plate 114 or away from the display screen cover plate 114 (i.e. towards the earpiece diaphragm 101 or away from the earpiece diaphragm 101). It should be noted that, in order to avoid the contact between the loop coil 102 and the earphone diaphragm 101 during the focusing process, the initial focusing position of the lens module 104 is designed as follows: the annular coil 102 is spaced apart from the earphone diaphragm 101 by a first predetermined distance, and a closest focusing distance (i.e., a maximum focusing distance in a direction close to the display screen cover plate 114) of the lens module 104 does not exceed the first predetermined distance, which can be designed according to a focusing requirement 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, which can realize both earpiece function and camera function, and in a form of separately arranging the earpiece structure and the camera structure in the prior art, the combined device can reduce the occupation of the internal space of the mobile terminal, and meanwhile, since the earpiece diaphragm 101 and the loop coil 102 are both annular, the lens module 104 can collect images through the hole between the loop coil 102 and the earpiece diaphragm 101, so only one functional hole needs to be opened on the display screen cover plate 114, which can meet the use requirements of the earpiece and the camera, reduce the number of holes on the display screen cover plate 114, and is more beneficial to the development of a full-screen.

Further, in the embodiment of the present invention, in order to ensure that the annular coil 102 can sufficiently abut against the receiver diaphragm 101 in the receiver operating mode, a height of the lens module 104 facing the end surface of the receiver diaphragm 101 is smaller than a height of the annular coil 102 facing the end surface of the receiver diaphragm 101, that is, the lens module 104 is located in the central hole of the annular coil 102, and the end surface of the lens module 104 facing the receiver diaphragm 101 is not exposed outside the central hole.

Further, in the embodiment of the present invention, for the initial state (i.e., the non-energized state) of the combined apparatus, the annular coil 102 may be designed to be in contact with the earpiece diaphragm 101, or a second preset distance may be spaced between the annular coil 102 and the earpiece diaphragm 101, where the second preset distance is greater than, equal to, or smaller than the first preset distance, and the specific situation may be designed according to actual requirements.

In the embodiment of the present invention, the initial state of the combination device is preferably: the ring-shaped coil 102 is abutted to the receiver diaphragm 101, so that when a receiver on the mobile terminal is started to work, the ring-shaped coil 102 can directly drive the receiver diaphragm 101 to vibrate according to an audio signal of the audio circuit 107, the ring-shaped coil 102 is not required to be firstly controlled to be abutted to the receiver diaphragm 101, then the receiver is used for sounding, and the time delay is reduced. Of course, the initial state of the combination device can also be selected as follows: the annular coil 102 and the receiver diaphragm 101 are separated by a first preset distance, so that when the camera is started to work, focusing can be directly performed according to a focusing driving signal of the motor driving circuit 108, and the annular coil 102 does not need to be controlled to drive the lens module 104 to move to an initial focusing position of the lens module 104, so that rapid focusing is realized, and time delay is reduced. It will be appreciated that the initial state of the combination device may also be selected to be: the ring coil 102 is located at a compromise position between the initial focusing positions of the earphone diaphragm 101 and the lens module 104, and the specific situation can be designed according to actual requirements.

Wherein, when the initial state (i.e. the non-power-on state) of the combination device is: when the annular coil 102 is abutted against the earphone diaphragm 101, before the annular coil 102 receives a focusing driving signal of the motor driving circuit 108 and drives the lens module 104 to move towards or away from the display screen cover plate 114 for focusing according to the focusing driving signal, the circuit control method further includes:

the loop coil 102 receives a first initial driving signal of the motor driving circuit 108, and moves a first preset distance in a direction away from the display screen cover 114 according to the first initial driving signal, so as to form an initial focusing position of the lens module 104.

That is, when the camera is started to work, the motor driving circuit 108 first applies a certain current (i.e., a first initial driving signal) to the loop coil 102, pulls the loop coil 102 away from the receiver diaphragm 101, stops pulling the loop coil 102 when the loop coil 102 is spaced from the receiver diaphragm 101 by a first predetermined distance, and records the current position as the initial focusing position of the lens module 104. After that, the motor driving circuit 108 sends a focusing driving signal to the loop coil 102, and controls the loop coil 102 to drive the lens module 104 to move in a larger amplitude, so as to achieve focusing.

Further, when the initial state of the combination device is: when the annular coil 102 and the earpiece diaphragm 101 are spaced by a second preset distance, before the annular coil 102 receives a focusing driving signal of the motor driving circuit 108 and drives the lens module 104 to move toward or away from the display screen cover plate 114 for focusing according to the focusing driving signal, the circuit control method further includes:

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

That is, when the camera is started to work, the motor driving circuit 108 first supplies a certain current (i.e., a second initial driving signal) to the loop coil 102, so that the loop coil 102 drives the lens module 104 to move in a direction away from or close to the display screen cover plate 114, and when the loop coil 102 and the earpiece diaphragm 101 are separated by a first preset distance, the loop coil 102 stops moving, and the current position is recorded as the initial focusing position of the lens module 104. After that, the motor driving circuit 108 sends a focusing driving signal to the loop coil 102, and controls the loop coil 102 to drive the lens module 104 to move in a larger amplitude, so as to achieve focusing.

If the second preset distance is greater than the first preset distance, the annular coil 102 is controlled to drive the lens module 104 to move towards the direction close to the display screen cover plate 114; if the second preset distance is smaller than the first preset distance, the annular coil 102 is controlled to drive the lens module 104 to move in a direction away from the display screen cover plate 114; if the second predetermined distance is equal to the first predetermined distance, the toroidal coil 102 remains stationary.

In order to ensure the user experience, in the embodiment of the present invention, when the lens module 104 is in the initial focusing position, the display screen of the mobile terminal is controlled to display the image collected by the lens module 104, so as to avoid the situation that the image collected by the camera is displayed on the display screen and the display screen is unstable when the lens module 104 is driven by the loop coil 102 to be in the initial focusing position.

Wherein, when the initial state of the combination device is: when the annular coil 102 and the receiver diaphragm 101 are spaced by a second preset distance, before the annular coil 102 receives an audio signal of the audio circuit 107 and drives the receiver diaphragm 101 to vibrate according to the audio signal to sound, the circuit control method further includes:

the loop coil 102 receives a third initial driving signal from the audio circuit 107, and moves in a direction approaching the earpiece diaphragm 101 according to the third initial driving signal, so as to interfere with the earpiece diaphragm 101.

That is, when the receiver is activated, the audio circuit 107 first applies a certain current (i.e., a third initial driving signal) to the loop coil 102, so that the loop coil 102 moves in a direction approaching the display cover 114, and the loop coil 102 interferes with the receiver diaphragm 101. After that, the audio circuit 107 sends an audio signal to the ring coil 102, and controls the ring coil 102 to drive the earphone diaphragm 101 to vibrate, so as to realize sound production.

Further, as shown in fig. 1, the lens module 104 includes: the lens 1042 is fixedly connected to the carrier 1041 and the lens 1042 arranged on the carrier 1041, that is, the lens 1042 is fixedly connected to the ring coil 102 through the carrier 1041, so that the ring coil 102 drives the lens 1042 to move toward or away from the display cover 114.

Further, as shown in fig. 2, the combination device further includes: the first elastic sheet 111 and/or the second elastic sheet 112. The first elastic piece 111 is disposed on one side of the lens module 104 facing the receiver diaphragm 101, and the second elastic piece 112 is disposed on one side of the lens module 104 facing away from the receiver diaphragm 101. The specific structural shapes of the first elastic sheet 111 and the second elastic sheet 112 may be selected according to actual requirements, which is not limited in the embodiments of the present invention.

The first elastic sheet 111 and the second elastic sheet 112 can balance the electromagnetic force to adjust the moving position of the lens module 104, so as to adjust the micro-distance of the lens 1042 and adjust the focusing plane, thereby achieving the purpose of clear image. For example, when both the elastic pieces are disposed, when the lens module 104 moves toward the display cover 114, the first elastic piece 111 may generate an acting force to the lens module 104 opposite to the moving direction of the lens module 104, and the second elastic piece 112 may also generate an acting force to the lens module 104 opposite to the moving direction of the lens module 104, and the sum of the acting forces of the first elastic piece 111 and the second elastic piece 112 balances the electromagnetic force, so as to prevent the lens module 104 from excessively moving toward the display cover 114, which may cause the loop coil 102 to collide with the earphone diaphragm 101. Similarly, when the lens module 104 moves away from the display cover 114, the first resilient tab 111 can generate an acting force on the lens module 104 opposite to the moving direction of the lens module 104, and the second resilient tab 112 can also generate an acting force on the lens module 104 opposite to the moving direction of the lens module 104, so as to balance the electromagnetic force and prevent the lens module 104 from excessively moving away from the display cover 114. It is understood that the direction of the force applied by the first elastic sheet 111 to the lens module 104 and the direction of the force applied by the second elastic sheet 112 to the lens module 104 are not necessarily the same, and in particular, the directions may be determined according to the stretching or compressing states of the two elastic sheets. And which shrapnel is arranged in the combined device can be selected according to actual requirements.

In the embodiment of the present invention, the first elastic sheet 111 and/or the second elastic sheet 112 may be further used to better control the loop coil 102 to abut against the earphone diaphragm 101, for example, in an initial state of the combination device, under the action of the first elastic sheet 111 and/or the second elastic sheet 112, the loop coil 102 may be better kept in an abutting state with the earphone diaphragm 101, or in an earphone working mode, under the action of the first elastic sheet 111 and/or the second elastic sheet 112, the loop coil 102 may be better controlled to continuously abut against the earphone diaphragm 101.

Wherein, this composite set still includes: the casing that the cover was located on the lens module 104, this casing plays the guard action to lens module 104, and it still has the effect of magnetic conduction simultaneously, improves the effective utilization of magnet 103, prevents the magnetic leakage. The housing has a lens through hole corresponding to the lens 1042 of the lens module 104, so as to prevent the lens 1042 from capturing an external image.

Wherein, as shown in fig. 2, the combination device further comprises: a bracket 113 for supporting. The bracket 113 may carry other structures of the assembly, such as the magnet 103, the toroidal coil 102, the lens module 104, etc.

Specifically, the first elastic sheet 111 is disposed between the lens module 104 and the housing, and the first elastic sheet 111 may be fixedly connected to the lens module 104, the housing, or both, and may be respectively connected to the lens module 104 and the housing, and the specific situation may be selected according to actual requirements. In the embodiment of the invention, the first elastic sheet 111 is preferably fixedly connected with the shell, so that the first elastic sheet 111 does not need to be driven to move all the time when the lens module 104 moves up and down, and the power consumption is reduced.

Specifically, the second elastic sheet 112 is disposed between the lens module 104 and the bracket 113, and the second elastic sheet 112 may be fixedly connected to the lens module 104, the bracket 113, or both the lens module 104 and the bracket 113, and may be selected according to actual requirements. In the embodiment of the invention, the first elastic sheet 111 is preferably fixedly connected with the bracket 113, so that the second elastic sheet 112 does not need to be driven to move all the time when the lens module 104 moves up and down, and the power consumption is reduced.

Further, in the embodiment of the present invention, the annular earphone diaphragm 101 may be integrally formed; or may be composed of two half-ring diaphragms 1011, as shown in fig. 3, specifically: the earpiece diaphragm 101 includes: two half-ring diaphragms 1011, the two half-ring diaphragms 1011 being connected together by a connecting glass 1012.

In summary, the combined device provided in the embodiments of the present invention can achieve both the receiver function and the camera function, because the receiver diaphragm 101 and the ring coil 102 are both annular, and the lens module 104 can collect images through the hole between the ring coil 102 and the receiver diaphragm 101, only one functional hole needs to be opened on the display screen cover plate 114, so that the usage requirements of the receiver and the camera can be met, the number of holes opened on the display screen cover plate 114 is reduced, which is more beneficial to the development of a full-screen, and meanwhile, the combined device can also reduce the occupation of the internal space of the mobile terminal.
