Fig. 1 is a schematic structural view of a sound-leakage-preventing electronic apparatus shown according to an exemplary embodiment. As shown in fig. 1, an embodiment of the present disclosure provides an anti-sound-leakage electronic apparatus, including: the bone conduction module comprises a body 1 and a bone conduction module 2 installed in the body 1. The main body 1 includes a display surface 11, a rear cover 12, and a side 13. The back cover 12 and the side 13 enclose a cavity with one open side, and the cavity is used for installing the bone conduction module 2. The bone conduction module 2 is used for outputting a first sound signal conducted through a solid. And, the display surface 11 is connected with the side 13 to block the open surface of the cavity to form the complete body 1. The display surface 11 is provided with a contact portion X for transmitting the first audio signal output from the bone conduction module 2.

When the electronic equipment provided by the embodiment of the disclosure is used, the user abuts the contact part X against the ear bone or the skull, the first sound signal output by the bone conduction module 2 is transmitted to the ossicle of the user through the contact part X, and then is received by the auditory nerve, and at the moment, the user hears the sound.

Since it is common practice for a user to place the upper part of the display surface 11 of the electronic device against the ear when he is receiving a call or playing audio in the earpiece mode. Therefore, the contact portion X is provided on the upper portion of the display surface 11. The upper portion of the display surface 11 is a portion above a center line along the longitudinal direction of the display surface 11. The contact portion X is provided centrally in the width direction of the display surface 11. Therefore, the use habit of the user is met, and the contact part X is attached to the position conveniently, so that the times of adjusting the electronic equipment by the user are reduced.

In addition, the contact portion X is disposed to protrude from the display surface 11 at a portion adjacent to the contact portion X, and the protruding contact portion X helps to abut against the facial skeleton of the user, thereby ensuring 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 by a solid body, so that the transmission of the first sound signal can be realized only when the contact portion X abuts against the ear bone or the skull of the user. Under the condition that first sound signal can't rely on the air conduction, the condition of leaking sound can no longer appear when using this electronic equipment output audio frequency, is showing improvement electronic equipment security performance, guarantee user privacy safety.

In the electronic equipment provided by the embodiment of the disclosure, the first sound signal conducted by the solid is output through the bone conduction module 2 and the contact part X, so that the influence of air flow is avoided, and the user experience is optimized.

Fig. 2 to 5 are schematic structural diagrams of electronic devices respectively shown according to different embodiments, wherein the schemes shown in fig. 2 to 4 employ the same implementation of the contact portion X, fig. 2 is a sectional view of the electronic device shown according to an exemplary embodiment, fig. 3 is a front view of the electronic device shown according to fig. 2, and fig. 4 is a front view of the electronic device shown according to another exemplary embodiment. The solution shown in fig. 5 uses another implementation of the contact portion X.

In one embodiment, as shown in fig. 2 and 3, the display surface 11 is provided with a mounting hole 111, and the mounting hole 111 communicates the inside and the outside of the body 1. The bone conduction module 2 includes a conduction member 21 extending from the mounting hole 111 out of the body 1, and a portion of the conduction member 21 extending out of the mounting hole 111 forms a contact portion X. The shapes of the mounting hole 111 and the conductive element 21 are not particularly limited, for example, the mounting hole 111 is a circular hole, a square hole, or a strip-shaped hole; the conductive material 21 has a cylindrical shape, a cubic shape, or the like.

In this embodiment, the bone conduction module 2 directly contacts the user through the conduction element 21, so as to realize the transmission of the first sound signal. By adopting the mode, the first sound signal has higher directivity, the loss of the first sound signal in the transmission process can be reduced, the definition of the first sound signal is improved, and the signal quality is optimized. Wherein, the transmitter 21 can be selected as a vibrator in the bone conduction module 2 to further reduce the loss of the first sound signal during the transmission process.

Optionally, a protective layer 211 is disposed on a portion of the conductive element 21 protruding out of the mounting hole 111, and the contact portion X is protected from abrasion by the protective layer 211.

Further, the protective layer 211 may be used to provide the touch portion X with a different tactile sensation from other portions of the display surface 11. For example, the protection layer 211 has a frosted structure to remind the user of the contact portion X being stuck in place by the tactile sensation difference when using the sound leakage prevention electronic apparatus.

Wherein the optional protective layer 211 is only provided on the end of the conductive member 21 protruding out of the mounting hole 111, or the protective layer 211 covers the portion of the conductive member 21 protruding out of the mounting hole 111.

It should be noted that, in this embodiment, the conduction element 21 is integrally packaged with other components in the bone conduction module 2, and in this case, 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 conductive element 21. In this case, the electronic apparatus further includes an earpiece module 3 disposed in the main body 1, the earpiece module 3 being disposed corresponding to the gap 112 for outputting a second sound signal, the second sound signal being propagated through the gas.

In this embodiment, the gap 112 between the transmitter 21 and the mounting hole 111 serves as a sound outlet of the earpiece module 3. Make the user can select solid transaudient mode or gaseous transaudient mode through setting up bone conduction module 2 and earphone module 3 simultaneously, richen electronic equipment's use mode. In addition, the mounting hole 111 matched with the conduction piece 21 is used as a sound outlet hole, so that an additional hole is prevented from being formed in the display surface 11, and the structural stability of the machine body 1 is improved.

The electronic device further comprises a controller 4 arranged in the body 1, wherein the controller 4 is used for controlling the bone conduction module 2 to output a first sound signal and controlling the earphone module 3 to output a second sound signal. During the use, controller 4 can control bone conduction module 2 and earphone module 3 output sound signal simultaneously, perhaps alternative control bone conduction module 2 and earphone module 3 output sound signal.

It can be understood that the switching of the two sound transmission modes of the solid sound transmission mode and the gas sound transmission mode is realized by switching and starting the bone conduction module 2 and the earphone module 3 through the controller 4, so that a user can select the sound transmission mode according to the requirement. In this embodiment, the electronic device is used as follows.

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

Alternatively, the correspondence between different preset use conditions and the sound transmission mode is stored in the controller 4. For example: the voice call with the contact a (preset use condition) corresponds to the solid-state sound transmission mode, and the voice call with the contact B (preset use condition) corresponds to the gas-state sound transmission mode.

When the controller 4 detects the preset use condition, the currently adopted sound transmission mode can be determined according to the corresponding relation, and then the bone conduction module 2 and/or the earphone module 3 are/is started 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 a 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 body 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 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 to protrude from the flat portion 113. In this case, the contact portion X is a part of the display surface 11. Wherein, the contact part X can be a strip shape, an arc shape or a block-shaped bulge.

Optionally, the contact portion X and the flat portion 113 are in smooth transition, 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, where the contact portion X has both functions of transmitting the first sound signal and displaying information. In order to simplify the processing difficulty of the display surface 11, a contact portion X is formed at an upper edge of the electronic device.

By adopting the electronic device provided by the embodiment, a through hole does not need to be formed in the display surface 11, which is beneficial to optimizing the structural stability of the display surface 11. Meanwhile, the design without through holes on the display surface 11 optimizes the dustproof and waterproof performance of the electronic equipment.
