Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

A first aspect of the embodiments of the present disclosure provides an electronic device for preventing sound leakage, and the electronic device can be selected from a mobile phone, a tablet computer, a wearable device, and the like.

FIG. 1 is a schematic structural diagram of an electronic device for preventing sound leakage according to an exemplary embodiment. As shown in FIG. 1 , an embodiment of the present disclosure provides an electronic device for preventing sound leakage. The electronic device includes a body 1 and a bone conduction module 2 installed in the body 1 . The fuselage 1 includes a display surface 11 , a back cover 12 , and a side edge 13 . The back cover 12 and the side edge 13 enclose a cavity with one side open, and the cavity is used for installing the bone conduction module 2 . The bone conduction module 2 is used for outputting the first sound signal conducted through the solid body. In addition, the display surface 11 is connected with the side edge 13 to block the open surface of the cavity to form a complete fuselage 1 . The display surface 11 is provided with a contact portion X for transmitting the first sound signal output by the bone conduction module 2 .

When using the electronic device provided by the embodiment of the present disclosure, the user presses the contact part X against the ear bone or the skull, and the first sound signal output by the bone conduction module 2 is transmitted to the user's ossicles through the contact part X, and is then transmitted to the ossicles of the user. received by the auditory nerve, when the user hears the sound.

Usually, when a user answers a call or plays audio in a handset mode, it is customary to press the upper part of the display surface 11 of the electronic device against the ear. Therefore, the contact portion X is provided on the upper portion of the display surface 11 . The upper part of the display surface 11 is the part above the center line along the longitudinal direction of the display surface 11 . In addition, the contact portion X is centrally provided along the width direction of the display surface 11 . This not only satisfies the user's usage habits, but also facilitates the contact part X to be in place, so as to reduce the number of times that the user adjusts the electronic device.

In addition, the contact portion X is protruding from the portion of the display surface 11 adjacent to the contact portion X, and the protruding contact portion X helps to stick to the user's facial skeleton to ensure effective conduction of the first sound signal.

In the embodiment of the present disclosure, the first sound signal output by the bone conduction module 2 is conducted through a solid body, so the first sound signal can only be transmitted when the contact portion X abuts against the user's ear bone or skull. In the case where the first sound signal cannot be conducted by air, there will be no sound leakage when the electronic device is used to output audio, which significantly improves the security performance of the electronic device and ensures user privacy.

It should also be noted that when using the electronic device in the related art, the airflow between the user and the fuselage will generate noise, so that the user cannot hear clear audio, which affects the user experience. In the electronic device provided by the embodiment of the present disclosure, the first sound signal conducted by the solid body is output through the bone conduction module 2 and the contact part X, which is no longer affected by the airflow, and the user experience is optimized.

FIGS. 2 to 5 are schematic structural diagrams of electronic devices according to different embodiments, wherein the solutions shown in FIGS. 2 to 4 use the same implementation of the contact portion X, and FIG. 2 is shown according to an exemplary embodiment. Cross-sectional views of the electronic device, FIG. 3 is a front view of the electronic device according to FIG. 2 , and FIG. 4 is a front view of the electronic device according to another exemplary embodiment. The solution shown in FIG. 5 adopts another implementation manner of the contact portion X.

In one embodiment, as shown in FIGS. 2 and 3 , the display surface 11 is provided with a mounting hole 111 , and the mounting hole 111 communicates with the inside and the outside of the fuselage 1 . The bone conduction module 2 includes a conducting member 21 extending from the mounting hole 111 to the body 1 , and the portion of the conducting member 21 extending out of the mounting hole 111 forms a contact portion X. The shapes of the mounting hole 111 and the conducting member 21 are not specifically limited, for example, the mounting hole 111 is a circular hole, a square hole, or a strip hole;

In this embodiment, the bone conduction module 2 directly contacts the user through the conduction member 24 to realize the transmission of the first sound signal. In this way, the first sound signal has a higher directivity, and can reduce the loss of the first sound signal during the propagation process, improve the clarity of the first sound signal, and optimize the signal quality. Wherein, the conducting member 21 can be selected as a vibrator in the bone conduction module 2, so as to further reduce the loss of the first sound signal during the propagation process.

Optionally, a protective layer 241 is provided on the portion of the conducting member 24 protruding from the mounting hole 111 , and the protective layer 241 protects the structure of the contact portion X and avoids wear.

In addition, the protective layer 241 can also be used to provide the contact portion X with a different tactile sensation from other parts of the display surface 11 . For example, the protective layer 241 has a frosted structure, so as to remind the user that the contact part X is in place by using the difference in tactile sensation when the electronic device for preventing sound leakage is used.

The optional protective layer 241 is only disposed on the end of the conducting member 24 extending out of the mounting hole 111 , or the protective layer 241 covers the portion of the conducting member 24 extending out of the mounting hole 111 .

It should be noted that, in this embodiment, the conductive member 24 is integrally packaged with other components in the bone conduction module 2, and at this time, the bone conduction module 2 has a special-shaped structure.

Further, in one embodiment, as shown in FIG. 4 , there is a gap 112 between the mounting hole 111 and the conducting member 24 . In this case, the electronic device further includes an earpiece module 3 disposed in the fuselage 1, the earpiece module 3 is disposed corresponding to the gap 112, and is used for outputting a second sound signal, and the second sound signal propagates through the gas.

In this embodiment, the gap 112 between the conducting member 24 and the mounting hole 111 is used as the sound outlet hole of the earphone module 3 . By setting the bone conduction module 2 and the earpiece module 3 at the same time, the user can choose the solid sound transmission mode or the gas sound transmission mode, thereby enriching the use of electronic equipment. Moreover, using the mounting hole 111 matched with the conducting member 24 as the sound outlet hole avoids opening additional holes on the display surface 11 , which helps to improve the structural stability of the fuselage 1 .

The electronic device further includes a controller 4 disposed in the body 1, the controller 4 is used to control the bone conduction module 2 to output the first sound signal, and the earpiece module 3 to output the second sound signal. When in use, the controller 4 can simultaneously control the bone conduction module 2 and the earpiece module 3 to output sound signals, or selectively control the bone conduction module 2 and the earpiece module 3 to output sound signals.

It can be understood that the switching of the bone conduction module 2 and the earpiece module 3 by the controller 4 realizes the switching of the two sound transmission modes of solid sound transmission and gas sound transmission, so that users can choose the expressive sound mode according to their needs. In this embodiment, the electronic device is used as follows.

Optionally, virtual keys corresponding to the solid sound transmission mode and the gas sound transmission mode are provided on the display surface 11 . The sound transmission mode corresponding to the currently triggered virtual key is determined by detecting the trigger operation, and then the controller 4 starts the bone conduction module 2 and/or the earpiece module 3 according to the determined sound transmission mode.

Optionally, the corresponding relationship between different preset usage conditions and sound transmission modes is stored in the controller 4 . For example, a voice call with contact A (preset usage conditions) corresponds to the solid-body sound transmission mode, and a voice call with contact B (preset usage conditions) corresponds to the gas sound transmission mode.

When the controller 4 detects the preset usage condition, it can determine the currently adopted sound transmission mode according to the corresponding relationship, and then activate the bone conduction module 2 and/or the earpiece module 3 according to the determined sound transmission mode.

In one embodiment, as shown in FIG. 5 , the bone conduction module 2 is disposed on the back side of the display surface 11 , and the portion of the display surface 11 corresponding to the bone conduction module 2 forms a contact portion X. In this embodiment, the bone conduction module 2 indirectly contacts the user through the display surface 11 .

It should be noted that the bone conduction module 2 will drive the display surface 11 to vibrate together, but since the display surface 11 is connected to the side 13 of the fuselage 1, it is difficult for the display surface 11 to output a strong first sound signal through vibration. In other words, even if the bone conduction module 2 is disposed against the display surface 11 , the sound leakage prevention effect can also be achieved.

Further, the display surface 11 further includes a flat portion 113 connected to the contact portion, and the contact portion X is disposed protruding from the flat portion 113 . In this case, the contact portion X serves as a part of the display surface 11 . Wherein, the contact portion X can be optionally a strip-shaped, arc-shaped, or block-shaped protrusion.

Optionally, the contact portion X and the flat portion 113 transition smoothly, so that the contact portion X forms a curved protrusion in the thickness direction of the electronic device, and the display surface 11 includes a flexible display screen. At this time, the contact portion X takes into account the transmission of the first sound signal. and the ability to display information. Also, in order to simplify the processing difficulty of the display surface 11, the contact portion X is formed at the upper edge of the electronic device.

With the electronic device provided in this embodiment, there is no need to open through holes on the display surface 11 , which helps to optimize the structural stability of the display surface 11 . At the same time, the design without through holes on the display surface 11 optimizes the dustproof and waterproof performance of the electronic device.
