Detailed Description

Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present disclosure and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the disclosure include all alternatives, modifications, and equivalents as may be included within the spirit and scope of the appended claims.

The sounding module is a moving-coil loudspeaker, which plays an extremely important role in the terminal equipment, but along with the higher sensitivity of the sounding module, the impedance of the sounding module is lower, and when the sounding module and the receiving module are combined, the impedance of the sounding module is changed from original 32 ohms to 6 ohms. Moreover, as the integration level of the terminal equipment is higher, the distance between the sounding module and other devices is closer.

When the large current fluctuates and the magnetic field changes near the sounding module, the sounding module can generate induced electromotive force, and under the condition that the impedance is reduced, the induced current in the sounding module can correspondingly become large, and the larger induced current leads to larger sounding interference of the sounding module, so that the use requirement is difficult to meet.

In the related embodiment, a switch is connected between the power amplifier and the sounding module and between the sounding module, and a resistor of about 26 ohms is introduced when the sounding module is used, and the resistor is switched to zero impedance when the sounding module is used, but the whole circuit structure is more complex due to the mode, and the use cost of the sounding module is higher.

To solve the above technical problems, as shown in fig. 1 and fig. 2, the embodiment of the disclosure provides a sounding module 1, which includes a magnetic component 11 and a vibrating diaphragm 12, wherein the magnetic component 11 is used for forming a magnetic field arranged along a first direction, the vibrating diaphragm 12 is disposed in the magnetic field, the vibrating diaphragm 12 includes a plurality of bending lines 121 and a plurality of metal conductors 122, the plurality of bending lines 121 and the plurality of metal conductors 122 are sequentially distributed at intervals along a second direction, and the second direction and the first direction are at a first preset angle, and the plurality of metal conductors 122 are sequentially connected end to end, so that induced currents generated by adjacent metal conductors 122 are mutually reduced.

It can be appreciated that, because the plurality of metal conductors 122 are sequentially connected end to end, and the plurality of bending lines 121 and the plurality of metal conductors 122 are sequentially and alternately distributed along the second direction, the current directions between the adjacent metal conductors 122 are opposite, therefore, when the plurality of metal conductors 122 are energized with alternating current, the adjacent metal conductors 122 are subjected to electromagnetic forces with opposite directions in the magnetic field generated by the magnetic assembly 11, so that the adjacent bending lines 121 are mutually close to or far away from each other in the second direction, and further continuous folding and unfolding of the vibrating diaphragm 12 are realized, and the sounding requirement is met.

Meanwhile, when large current fluctuation exists near the sounding module 1 and a magnetic field is changed, the adjacent metal conductors 122 generate induced electromotive forces with opposite directions under the action of the magnetic field, and the opposite induced electromotive forces are mutually reduced, so that the induced current in the sounding module 1 is effectively reduced, the electromagnetic interference resistance of the sounding module 1 is improved, and the sounding module 1 with higher performance is further ensured to meet the use requirements of users.

In addition, the arrangement mode of the plurality of metal conductors 122 reduces the induced current in the sounding module 1, avoids the arrangement of circuit elements such as a change-over switch and the like, thereby avoiding the complexity of a circuit and further reducing the use cost of the sounding module 1.

It should be noted that, the magnetic assembly 11 is used to form the magnetic field arranged along the first direction, and the specific type of the magnetic assembly 11 may be set according to actual needs, which is not limited.

The first direction may be any direction, and for example, when the sound emitting module 1 is applied to a terminal device, the first direction may be a thickness direction, a length direction, a width direction, and the like of the terminal device.

The magnetic field arranged along the first direction means that the magnetic pole direction of the magnetic field is the first direction, i.e. the direction from the N pole to the S pole or the direction from the S pole to the N pole of the magnetic field is the first direction.

The bending lines 121 are used for bending the diaphragm 12, and since the plurality of bending lines 121 and the plurality of metal conductors 122 are sequentially spaced apart along the second direction, the metal conductors 122 are disposed on both sides of each bending line 121, so to speak, the bending lines 121 are disposed on both sides of each metal conductor 122.

The second direction may be any direction, and for example, when the sound emitting module 1 is applied to a terminal device, the second direction may be a thickness direction, a length direction, a width direction, and the like of the terminal device. And, the first preset angle may be ninety degrees, or an angle approaching ninety degrees.

The specific type of metal conductor 122 may be set according to actual needs, and is not limited thereto, and the metal conductor 122 may be a metal trace printed on a flexible circuit board, for example.

The mutual cancellation of the induced currents generated by the adjacent metal conductors 122 means that the induced currents generated by the adjacent metal conductors 122 are partially or completely cancelled, so that the induced currents in the sounding module 1 are reduced below the hearing threshold.

As shown in fig. 2, in some embodiments, the metal conductor 122 includes a body portion 1221, a first electrode 1222 and a second electrode 1223, the plurality of bending lines 121 and the plurality of body portions 1221 are sequentially spaced apart in a second direction, and the length direction and the second direction of the body portion 1221 are at a second predetermined angle, the first electrode 1222 is disposed at a first end of the body portion 1221, and the second electrode 1223 is disposed at a second end of the body portion 1221, wherein the first electrode 1222 and the second electrode 1223 between adjacent metal conductors 122 are connected.

It should be noted that the main body portion 1221 is used for conducting current, and the specific type of the main body portion 1221 may be set according to actual needs, which is not limited thereto, and the main body portion 1221 may be a metal trace printed on a flexible circuit board, for example. And, the second preset angle may be ninety degrees, or an angle near ninety degrees.

Wherein, the larger the width of the main body 1221, the larger the conducted current, and the larger the stress of the metal conductor 122 in the magnetic field generated by the magnetic component 11, thereby ensuring that the sounding module 1 has a stronger sounding capability.

The first electrode 1222 and the second electrode 1223 are also used for conducting current, and specific types of the first electrode 1222 and the second electrode 1223 may be set according to actual needs, which is not limited thereto, and the first electrode 1222 and the second electrode 1223 may be metal traces printed on a flexible circuit board, wherein the length directions of the first electrode 1222 and the second electrode 1223 may be perpendicular to the length direction of the main body portion 1221.

It can be appreciated that when the plurality of metal conductors 122 are energized with alternating current, the adjacent metal conductors 122 are subjected to electromagnetic forces with opposite directions in the magnetic field generated by the magnetic steel 111, so that the adjacent bending lines 121 are close to or far away from each other in the second direction, thereby realizing continuous folding and unfolding of the diaphragm 12 and meeting the requirement of sound production.

Meanwhile, by arranging the first gap 112 between the magnetic steel 111 and the diaphragm 12, a certain movable space is provided for folding and unfolding the diaphragm 12, so that stable sounding of the diaphragm 12 is ensured.
