[0038] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0039] The present invention is based on the inventor's discovery and understanding of the following facts and problems:

[0040] When an electronic device adopts a dual-speaker symmetrical stereo design, the upper speaker located on the top is used for both the sound of the call receiver and the external projection of the speaker. In order to adapt to the different usage methods of the upper speaker, the top of the electronic device in the related art is usually also provided with an upper sound hole and a narrow slit hole for the screen receiver. The upper sound hole is mainly used for the external projection of the sound of the upper speaker, and the sound emitted is usually louder, while the narrow slit hole is mainly used for the sound of the upper speaker used as the call receiver, and the sound emitted is smaller than that of the upper sound hole.

[0041] However, the upper sound hole and the narrow slit hole in the related art usually share a sound cavity, that is, the sound outlet channels 13 of the upper sound hole and the narrow slit hole overlap, which makes the sound of the user leak out from both the upper sound hole and the narrow slit hole at the same time during a call. The sound leaking out from the upper sound hole causes the problem of loud external sound and poor privacy of the call.

[0042] The sound output module of an embodiment of the present invention is described below.

[0043] The sound output module of the embodiment of the present invention comprises a housing 1 and a sound-blocking component 2. The housing 1 is provided with a first hole 11 and a second hole 12, wherein the first hole 11 is used for the sound output of the speaker, and the second hole 12 is used for the sound output of the receiver during a call.

[0044] like Figure 1 As shown, both the first hole 11 and the second hole 12 can be provided at the top of the housing 1, wherein the first hole 11 can be a circular hole and can be provided in plurality, and the plurality of first holes 11 can be arranged at intervals along the left-right direction, so as to ensure the volume of the sound output. The second hole 12 can be a linear long narrow slit hole, and the second hole 12 can also extend along the left-right direction.

[0045] The sound-blocking component 2 has a first form and a second form. In the first form, at least a portion of the sound-blocking component 2 blocks the first hole 11 so that the sound during a call can only be emitted from the second hole 12. In the second form, the sound-blocking component 2 releases the blockage of the first hole 11 so that the sound during non-calls can be emitted from the first hole 11 and the second hole 12.

[0046] For example, the sound insulation component 2 can be installed in the housing 1 and can be located below the first hole 11. The overall shape of the sound insulation component 2 is variable, and the variable form of the sound insulation component 2 includes a first form and a second form.

[0047] Specifically, the height of the sound-proofing component 2 in the vertical direction is adjustable. When the height dimension of the sound-proofing component 2 becomes smaller, the sound-proofing component 2 can be switched to the second state. Figure 2 As shown, the upper part of the sound-blocking component 2 will move downward and can be separated from the shell 1 above the sound-blocking component 2, that is, the sound-blocking component 2 does not block the first hole 11. At this time, the external sound of the speaker can leak out through the first hole 11 and the second hole 12, thereby ensuring the need for external sound with a larger volume.

[0048] When the height dimension of the sound-proof component 2 becomes larger, the sound-proof component 2 can be switched to the first state. Figure 3 As described, the upper part of the sound-blocking component 2 will move upward and come into contact with the shell 1 above the sound-blocking component 2, that is, the sound-blocking component 2 will block the first hole 11 on the shell 1. At this time, the sound of the speaker serving as the earpiece during a communication call can only leak out from the second hole 12, thereby avoiding the problem of loud external sound caused by the sound of the earpiece leaking out of the first hole 11, thereby improving the privacy of the call and avoiding the leakage of call information.

[0049] In some embodiments, the sound insulation component 2 includes a movable component 21 and a fixed component 22. The movable component 21 has a first position and a second position. In the first form, the movable component 21 is located at the first position and blocks the first hole 11. In the second form, the movable component 21 is located at the second position to release the blockage of the first hole 11. The fixed component 22 is connected to the movable component 21 and is used to drive the movable component 21 to switch between the first position and the second position.

[0050] For example, Figure 2 and Figure 3 As shown, both the movable component 21 and the fixed component 22 can be assembled in the housing 1 , wherein the movable component 21 can be located above the fixed component 22 and between the fixed component 22 and the first hole 11 on the housing 1 .

[0051] The movable part 21 can move up and down relative to the fixed part 22, and in the process of the movable part 21 moving up and down, the movable part 21 has a first position and a second position. The fixed part 22 is connected to the movable part 21 and can drive the movable part 21 to switch back and forth between the first position and the second position. The fixed part 22 can be a device with a driving function such as a rope fixed part 22, a gear fixed part 22, etc.

[0052] like Figure 3 As shown, when in use, the fixed component 22 can drive the movable component 21 to move upward, and the movable component 21 switches to the first position. At this time, the position change of the movable component 21 will also make the sound-proof component 2 switch to the first form as a whole, so that the first hole 11 can be blocked during a call.

[0053] When the fixed part 22 drives the movable part 21 to move downward, Figure 2 As shown, the movable part 21 is switched to the second position. At this time, due to the change in the position of the movable part 21, the sound-blocking component 2 is also switched to the second form as a whole, thereby releasing the blockage of the first hole 11 in the non-call situation.

[0054] By means of the arrangement of the movable part 21 and the fixed part 22, the sound-blocking component 2 can switch to different modes in the calling and non-calling situations, thereby realizing the automation of control and meeting the needs of use.

[0055] In some embodiments, the fixed component 22 drives the movable component 21 to switch between the first position and the second position through magnetic force. For example, the movable component 21 can be kept in the second position by a spring or other components under normal conditions, thereby meeting the need for sound to be emitted through the first hole 11 and the second hole 12 under normal conditions.

[0056] When making a call, the fixed component 22 can generate magnetism by passing an electric current or the like. At this time, the magnetic force of the fixed component 22 can repel the movable component 21 upward, thereby switching the movable component 21 to the first position. During the call, the sound of the earpiece can only leak out from the second hole 12, thereby ensuring the privacy of the call.

[0057] In some embodiments, there is a magnetic attraction between at least a portion of the movable component 21 and at least a portion of the fixed component 22, and the sound-absorbing component 2 can be maintained in the second form under the action of the magnetic attraction.

[0058] For example, the movable part 21 may be magnetic, and the fixed part 22 may be a magnetic conductor 211, so that under normal conditions, there is always a magnetic attraction between the movable part 21 and the fixed part 22, and the movable part 21 can be kept in the second position under the action of the magnetic attraction, that is, Figure 2The position shown by the movable part 21 meets the need of using the sound outside when not making a call under normal circumstances.

[0059] In some embodiments, one of the movable part 21 and the fixed part 22 includes a magnet 211 for generating magnetic attraction, and the other includes a coil 221. When current is passed through the coil 221, a magnetic repulsion force can be generated between the coil 221 and the magnet 211. Under the action of the magnetic repulsion force, the sound-absorbing component 2 can switch from the second form to the first form.

[0060] For example, Figure 4 and Figure 6 As shown, the magnet 211 can be arranged on the movable part 21, and the coil 221 can be arranged on the fixed part 22. When in use, the magnet 211 can generate a magnetic attraction between the movable part 21 and the fixed part 22, so that the movable part 21 can be kept in the second position. When a communication call is required, a current can be passed into the coil 221. At this time, the coil 221 can generate a magnetic force, and the magnetic force generated by the coil 221 and the magnetic force of the magnet 211 are a pair of magnetic repulsion forces, that is, when the N pole of the magnet 211 is facing downward, the N pole of the magnetic force generated by the coil 221 is facing upward. By means of the magnetic repulsion between the coil 221 and the magnet 211, the magnet 211 can be pushed upward, thereby facilitating the switching of the movable part 21 from the second position to the first position, and then the sealing and blocking of the first hole 11 can be achieved.

[0061] In some other embodiments, the coil 221 may also be provided on the movable component 21, and the magnet 211 may be provided on the fixed component 22. Under normal circumstances, the coil 221 may be maintained in the first position by components such as springs. When the sound needs to be played outward, current may be passed through the coil 221, and the movable component 21 may be switched to the second position by the magnetic attraction between the coil 221 and the magnet 211.

[0062] In some embodiments, Figures 4 to 6 As shown, the movable component 21 includes a sound-proof plate 212 for sealing the first hole 11. The sound-proof plate 212 can be roughly rectangular and can be made of sound-proof material. When in use, the upper surface of the sound-proof plate 212 can be in contact with the inner wall surface of the shell 1, thereby sealing the first hole 11.

[0063] like Figure 5 As shown, the sound-proof plate 212 is provided with a first annular groove 2121, which can be provided at the bottom side of the sound-proof plate 212, and the first annular groove 2121 can be in a square ring shape, and the magnet 211 can also be in a square ring shape and embedded in the first annular groove 2121. Specifically, as Figure 4 As shown, the upper surface of the magnet 211 may be provided with a first adhesive 213 , and the magnet 211 may be bonded and fixed in the first annular groove 2121 by the first adhesive 213 .

[0064] The setting of the sound-proofing plate 212 can enhance the sound-proofing effect and further avoid the situation where the sound is too loud. The setting of the first annular groove 2121 facilitates the installation and fixation of the magnet 211, and can also make use of the internal space of the sound-proofing plate 212, thereby avoiding the situation where the height dimension of the movable part 21 in the up and down direction is large, which is not conducive to lightweight and miniaturized design.

[0065] In some embodiments, Figure 6 and Figure 7 As shown, the fixed component 22 includes a driving shell 222, which can be generally in the shape of a rectangular parallelepiped. The driving shell 222 is magnetic or magnetically conductive. The driving shell 222 is used to generate a magnetic attraction force with the movable component 21, so that the movable component 21 can be kept in the second position under normal conditions, thereby facilitating the external projection of sound.

[0066] It should be noted that the driving housing 222 can be made of magnetically conductive materials such as steel. In some other embodiments, the driving housing 222 itself can also have a certain degree of magnetism, so that the movable part 21 can be better attracted to the driving housing 222, but the magnetic attraction force is smaller than the magnetic repulsion force generated between the coil 221 and the magnet 211 after the coil 221 is energized by current.

[0067] like Figure 6 and Figure 7 As shown, the driving housing 222 is provided with a second annular groove 2221, which can be provided at the bottom side of the driving housing 222, and the coil 221 and the second annular groove 2221 can both be square ring-shaped, and the coil 221 is embedded in the second annular groove 2221. This facilitates the installation and fixation of the coil 221, avoids the situation where the coil 221 is exposed to the outside, and improves the protection effect.

[0068] In some embodiments, the fixing component 22 further includes a cover 223, the shape of which matches the shape of the notch of the second annular groove 2221, that is, the cover 223 may be in a square ring shape, and the cover 223 may seal and block the notch of the second annular groove 2221, thereby shielding and fixing the coil 221. Optionally, the cover 223 may be connected and fixed to the driving housing 222 by means of snaps, bonding, etc.

[0069] In some embodiments, Figure 4 and Figure 6 As shown, the sound insulation component 2 includes a damping member 23, which acts between the movable part 21 and the fixed part 22. The damping member 23 can be a spring or the like. The damping member 23 can be fixed between the sound insulation plate 212 and the driving housing 222. For example, the top end of the damping member 23 can be connected to the sound insulation plate 212, and the bottom end of the damping member 23 can be connected to the driving housing 222.

[0070] The damping member 23 is used to generate a damping effect during the switching process of the movable component 21 between the first position and the second position to buffer the relative movement of the movable component 21 and the fixed component 22. This avoids the situation where the movable component 21 rigidly touches other components and ensures the smoothness of movement.

[0071] In some embodiments, one of the movable component 21 and the fixed component 22 is provided with a shaft body 2122, and the other is provided with a sleeve 2222. The shaft body 2122 is plugged into the sleeve 2222 to realize the sliding assembly of the movable component 21 and the fixed component 22, and the damping member 23 is sleeved on the outer peripheral side of the shaft body 2122 and the sleeve 2222.

[0072] For example, Figure 5 As shown, the shaft body 2122 can be integrally formed and arranged on the bottom side of the sound-proof plate 212. The shaft body 2122 can be cylindrical, and there can be multiple shaft bodies 2122, specifically, there can be two, three, four, etc. Figure 8 As shown, the shaft sleeve 2222 can be integrally formed on the top side of the driving housing 222 , the shaft sleeve 2222 can be annular and cylindrical, and the number of the shaft sleeves 2222 can be the same as the number of the shaft bodies 2122 .

[0073] When assembling the movable part 21 and the fixed part 22, multiple shaft bodies 2122 can be plugged into the sleeve 2222 in a one-to-one manner, so that the sliding assembly of the movable part 21 and the fixed part 22 can be achieved, and the guiding property of the movement of the movable part 21 can be improved by the limiting cooperation between the shaft body 2122 and the sleeve 2222, thereby ensuring the accuracy of the movement of the movable part 21 and further ensuring the sealing effect of the first hole 11.

[0074] It is understandable that, in some other embodiments, the shaft body 2122 may also be disposed on the driving housing 222 , and the shaft sleeve 2222 may also be disposed on the sound insulation plate 212 .

[0075] Optionally, a plurality of damping members 23 may be provided, and the plurality of damping members 23 may be sleeved on the outer circumference of the corresponding shaft body 2122 and shaft sleeve 2222 in a one-to-one correspondence.

[0076] In some embodiments, the fixing component 22 is fixedly connected to the housing 1, specifically, as Figure 6 As shown, the bottom side of the fixed component 22 may be provided with a second adhesive 224, and the fixed component 22 may be bonded and fixed to the housing 1 by the second adhesive 224. The movable component 21 is movably assembled with the fixed component 22 by means of sliding or the like, so that the shape of the sound-damping component 2 can be adjusted by changing the position of the movable component 21.

[0077] In some embodiments, Figures 2 to 4As shown, the sound output module also includes a sealing bracket 3, which is arranged in the housing 1. The sealing bracket 3 is provided with a third hole 31, and the third hole 31 is arranged opposite to and connected with the first hole 11. In the first form, the movable part 21 is in contact with the sealing bracket 3 and blocks the third hole 31. The setting of the sealing bracket 3 can play a role in filling the gap of the housing 1, thereby ensuring the compactness and closedness of the structure.

[0078] In some embodiments, Figure 2 and Figure 3 As shown, the housing 1 is provided with a channel 13, the channel 13 is used to propagate sound, the first hole 11 and the second hole 12 are both connected to the channel 13, and the sound-blocking component 2 and the sealing bracket 3 are both arranged in the channel 13. The provision of the channel 13 facilitates the directional propagation of sound on the one hand, and also provides installation space for the sound-blocking component 2, etc., and improves the convenience of installation.

[0079] In some embodiments, the sound module includes a sound generating component 4, such as Figure 2 and Figure 3 As shown, the generating component can be a speaker, the sound-generating component 4 is arranged in the channel 13 and is used to generate sound, and the first hole 11, the sound-blocking component 2, and the sound-generating component 4 can be arranged in sequence from top to bottom, so as to ensure the volume of the external sound, and the second hole 12 and the sound-generating component 4 can be staggered in the left and right directions, which is beneficial to reduce the volume of the sound leaked from the second hole 12.
