Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0038] The following combination Figures 1-10 An electronic device according to an embodiment of the present application is described.

[0039] It should be noted that the electronic device of the present application can be a mobile electronic device, such as a mobile phone, tablet computer, watch or smart wearable device, etc.; it can also be a non-mobile electronic device, such as a PC, etc.

[0040] like Figure 1 As shown, the electronic device according to some embodiments of the present application includes: a speaker 110, a cam mechanism 120 and a driving device 130.

[0041] In this embodiment, the speaker 110 may be a directional speaker for directionally propagating a sound source, such as propagating the sound in a narrowband sound beam along a specified direction.

[0042] The speaker 110 can control the propagation direction of the sound source and the coverage range of the sound waves.

[0043] The speaker 110 is rotatably connected to the electronic device.

[0044] Specifically, the speaker 110 may be rotatably connected to the frame 170 of the electronic device.

[0045] The speaker 110 may be a sheet-like structure with a sound outlet provided on its outer surface. The outer surface faces the outside of the electronic device, and the inner surface faces the inside of the electronic device.

[0046] Specifically, the inner surface of the speaker 110 is rotatably connected to the electronic device.

[0047] The cam mechanism 120 cooperates with the driving device 130 to drive the speaker 110 to rotate.

[0048] like Figure 4-Figure 6 As shown, the cam mechanism 120 may be a disc-shaped cam, wherein Figure 4 For the front view, Figure 5 This is a schematic diagram of the back side. Figure 6 It is a side view.

[0049] like Figure 1 and Figure 2As shown, in some embodiments, the cam profile of the cam mechanism 120 contacts the speaker 110 . During the rolling process of the cam mechanism 120 , the cam profile and the inner surface of the speaker 110 move relative to each other, thereby driving the speaker 110 to deflect.

[0050] The driving device 130 is connected to the cam mechanism 120 in a power-connected manner and is used to drive the cam mechanism 120 to rotate.

[0051] For example, the driving device 130 may be a motor or an electrical machine, etc., which is not limited in this application.

[0052] like Figure 5 As shown, the connection point between the driving device 130 and the cam mechanism 120 is the center of the base circle of the cam mechanism 120 .

[0053] One cam mechanism 120 corresponds to one driving device 130 .

[0054] In the present application, the number of the cam mechanism 120 may be one or more.

[0055] During actual implementation, the driving device 130 drives the cam mechanism 120 to rotate around the center of the base circle with the center of the base circle as the rotation center point, so that the cam mechanism 120 drives the speaker 110 to move relative to it.

[0056] It can be understood that during the rotation of the cam mechanism 120, the position of the center of the base circle remains unchanged, and during the rotation of the cam mechanism 120, the distance between the point where the cam profile contacts the speaker 110 and the center of the base circle changes with the rotation of the cam mechanism 120, realizing a movement from short to long (or from long to short), so as to drive the speaker 110 in contact with the cam profile to realize a follower movement from low to high (or from high to low), thereby changing the orientation of the outer surface of the speaker 110.

[0057] During the research and development process, the inventor discovered that there is a technology in the related art that adjusts the direction of the speaker based on a connecting rod mechanism, but the connecting rod mechanism can only adjust the direction of the speaker within a certain range, and the scope of application is small; in addition, the connecting rod mechanism requires a large space and is limited by the volume of electronic equipment. Therefore, this technology cannot be applied to electronic equipment.

[0058] In the present application, by using a cam mechanism 120 to adjust the orientation of the speaker 110, directional adjustment within a wider range can be achieved with higher control accuracy; in addition, the structure provided in the present application involves fewer components and occupies less volume, and can be flexibly arranged in electronic devices (especially smaller mobile electronic devices), with universality and flexibility.

[0059] According to the electronic device of the embodiment of the present application, a cam mechanism 120 is provided in contact with the speaker 110, and a driving device 130 is used to drive the cam mechanism 120 to rotate to drive the speaker 110 to deflect, thereby changing the orientation of the outer surface of the speaker 110 to accurately control the propagation direction of the sound source, thereby improving the flexibility of the voice playback of the electronic device. The structure is simple, occupies a small space and is easy to implement.

[0060] like Figure 4 As shown, according to some embodiments of the present application, the profile of the cam mechanism 120 includes a straight line segment and a curved line segment.

[0061] In this embodiment, the cam mechanism 120 is a disc cam, wherein one end of a straight segment is connected to one end of a curved segment, and the other end of the straight segment is connected to the other end of the curved segment.

[0062] The curved segment is used to contact the speaker 110 .

[0063] It should be noted that the number of curve segments can be one, or two or more.

[0064] In some embodiments, the number of curved segments is one, one end of the straight line segment is connected to one end of the curved segment, the other end of the straight line segment is connected to the other end of the curved segment, and the distance from a point on the curved segment to the center of the base circle of the cam mechanism 120 gradually decreases from one end to the other end of the curved segment.

[0065] In other embodiments, the curve segment includes a first sub-curve segment and a second sub-curve segment, wherein the distance from a point on the first sub-curve segment to the center of the base circle of the cam mechanism 120 gradually decreases from one end to the other end of the first sub-curve segment, and the second sub-curve segment is an arc with the center of the base circle as the center, and one end of the second sub-curve segment is connected to the end of the first sub-curve segment where the point closest to the center of the base circle is located.

[0066] like Figure 2 As shown, at this time, the cam mechanism 120 is in the initial position, and the cam mechanism 120 begins to rotate around the center of the base circle. For example, when rotating counterclockwise around the center of the base circle, the contact position between the cam mechanism 120 and the speaker 110 gradually moves from the point on the second sub-curve segment with the shortest distance from the center of the base circle (i.e., the point corresponding to the initial position) to the point on the second sub-curve segment with the longest distance from the center of the base circle, as shown in FIG. Figure 1 As shown, it eventually reaches the position of the point on the second sub-curve segment that is the longest distance from the center of the base circle (not shown in the figure), thereby driving the speaker 110 to move from the low position to the middle position and finally to the highest position.

[0067] According to the electronic device of the embodiment of the present application, by setting the distances between the points on the curved segments in the profile of the cam mechanism 120 and the center of the base circle to unequal distances, adjustment of any height within a certain range can be achieved, thereby enabling the speaker 110 to be deflected at any angle within a certain range, with high adjustment accuracy and strong flexibility.

[0068] Continue to refer Figure 1 or Figure 2 According to some embodiments of the present application, the speaker 110 is provided with a stepped surface.

[0069] In this embodiment, a side of the stepped surface of the speaker 110 that faces away from the outer surface of the speaker 110 contacts the cam profile of the cam mechanism 120 .

[0070] During actual implementation, the cam mechanism 120 rotates around the center of the base circle, and the height of the point where the cam profile contacts the step surface changes accordingly, thereby driving the speaker 110 to move accordingly, so that the outer surface of the speaker 110 can achieve deflection at different angles.

[0071] According to the electronic device of an embodiment of the present application, a step surface is set on the speaker 110, and the cam profile is in contact with the step surface so that the cam profile rolls along the step surface, thereby limiting the area in which the cam profile moves relative to the speaker 110 to improve the accuracy of control.

[0072] According to some embodiments of the present application, there are at least two cam mechanisms 120 .

[0073] In this embodiment, the speaker 110 is rotatably connected to the electronic device via a ball joint structure, such as being connected to the frame 170 of the electronic device via the ball joint structure.

[0074] The ball joint structure is used to fix the speaker 110 so that it does not separate from the electronic device, and is used to ensure that the speaker 110 can be rotated or flipped in any direction.

[0075] Specifically, the inner surface of the speaker 110 is connected to the electronic device via a ball joint structure.

[0076] The included angle between the axes of at least two cam mechanisms 120 is α, and 0°<α<180°.

[0077] For example, the angle between the axes of the two cam mechanisms 120 may be 90° or 60°, etc., which is not limited in this application.

[0078] In some embodiments, the speaker 110 may be a rectangular parallelepiped structure; then at least two cam mechanisms 120 may be respectively disposed at adjacent sides of the speaker 110 , and the movement of the at least two cam mechanisms 120 may drive the speaker 110 to deflect in different planes.

[0079] For example, by controlling the rotation of the cam mechanism 120 disposed in front of the speaker 110, the speaker 110 can be driven to flip forward and backward; by controlling the rotation of the cam mechanism 120 disposed on the right side of the speaker 110, the speaker 110 can be driven to flip left and right. Driven by the two cam mechanisms 120, the speaker 110 can be driven to flip forward and backward and left and right at the same time, thereby driving the speaker 110 to deflect in different planes.

[0080] According to the electronic device of the embodiment of the present application, by providing at least two cam mechanisms 120 and limiting the angle between the axes of the at least two cam mechanisms 120 to between 0-180°, the speaker 110 can be simultaneously flipped forward and backward and left and right, achieving multi-sided flipping, thereby enabling it to face the desired direction more accurately, significantly improving the precision and accuracy of control.

[0081] like Figure 3 As shown, according to some embodiments of the present application, there may be four cam mechanisms 120 .

[0082] In this embodiment, four cam mechanisms 120 are respectively disposed around the speaker 110 , and the four cam mechanisms 120 are symmetrically arranged at equal distances.

[0083] For example, the speaker 110 can be a rectangular structure, and the four cam mechanisms 120 are respectively arranged near the four sides of the speaker 110. The cam mechanisms 120 arranged near the front and rear sides drive the speaker 110 to deflect forward and backward, and the cam mechanisms 120 arranged near the left and right sides drive the speaker 110 to deflect left and right.

[0084] For another example, the speaker 110 may be a pancake-shaped structure, and the four cam mechanisms 120 may be equidistantly disposed on the circumference of the speaker 110 .

[0085] According to the electronic device of the embodiment of the present application, by symmetrically disposing four cam mechanisms 120 around the speaker 110 , it helps to improve the driving stability, thereby achieving stable deflection of the speaker 110 .

[0086] like Figure 8 As shown, according to some embodiments of the present application, the electronic device may further include: a positioning device and a mainboard 140 .

[0087] In this embodiment, the positioning device is used to determine the user's location.

[0088] Furthermore, the user location may include a face location.

[0089] The positioning device may include: a positioning device based on sound, a positioning device based on image recognition, a positioning device based on Bluetooth or other positioning devices.

[0090] For example, when the positioning device is a sound-based positioning device, the positioning device may include a microphone for collecting user sound waves and then determining the user's position based on information such as the propagation direction or attenuation degree of the user's sound waves.

[0091] For another example, in the case where the positioning device is a positioning device based on image recognition, the positioning device may include an image sensor, and identify the user's position by identifying the user (or face, etc.) through the image sensor.

[0092] For another example, when the positioning device is a Bluetooth-based positioning device, the user can be allowed to wear Bluetooth-related accessories (such as Bluetooth glasses) and the user's location can be determined through Bluetooth positioning and other technologies.

[0093] In actual use, you can freely choose the best positioning method based on the actual scenario, and this application does not limit it.

[0094] The main board 140 may be a printed circuit board (PCB).

[0095] The mainboard 140 is electrically connected to the positioning device and the driving device 130 respectively, and is used to receive the user position sent by the positioning device, generate a control instruction for controlling the rotation of the driving device 130 based on the user position, and send the control instruction to the driving device 130.

[0096] The control instruction is used to control the driving device 130 to rotate so as to drive the cam mechanism 120 to drive the outer surface of the speaker 110 to move toward a direction corresponding to the user's position.

[0097] In actual implementation, the user's location (e.g., face location) can be identified through location recognition technologies such as the direction of user voice propagation and attenuation, or location recognition technologies such as Bluetooth technology, or location recognition technologies such as cameras.

[0098] Through the identified user position, the program built into the mainboard 140 determines the optimal deflection angle (i.e., target direction) of the speaker 110 based on the identified user position, and controls the driving device 130 to adjust the deflection angle of the speaker 110 to achieve directional sound conduction to the user position area.

[0099] In other embodiments, the mainboard 140 can also adjust the control instructions in real time based on changes in the user's position, so that the speaker 110 changes its direction accordingly based on changes in the user's position, thereby providing a directional sound conduction function that realizes position tracking based on changes in the user's position.

[0100] The following combination Figure 10 , the control logic of the electronic device of this application is specifically described.

[0101] like Figure 10 As shown, during normal operation of the electronic device, the positioning device in the electronic device determines the user's position information (such as the face position) and sends the position information to the main board 140;

[0102] The mainboard 140 determines a target orientation of the speaker 110 based on the position information, and generates a control instruction for adjusting the orientation of the speaker based on the target orientation;

[0103] The driving device 130 drives the cam mechanism 120 to rotate based on the received control instruction, so as to drive the speaker 110 to deflect toward the target direction.

[0104] Continue to refer Figure 10 In some embodiments, when the user's position changes, the mainboard 140 recognizes the change in the user's position, updates the position information, and adjusts the control instructions accordingly based on the updated position information to adjust the rotation of the driving device 130 and then adjust the deflection direction of the speaker 110, so that the speaker 110 can track the change in the user's position and change accordingly.

[0105] According to the electronic device of the embodiment of the present application, the deflection angle of the speaker 110 is determined by the original positioning device in the electronic device and the main board 140, and the driving device 130 drives the cam mechanism 120 to rotate based on the deflection angle to adjust the deflection angle of the speaker 110, so that the sound is directionally transmitted to the direction corresponding to the user's position, which not only avoids the discomfort caused by the use of headphones, but also ensures the privacy of the sound, avoids sound pollution to others, improves the user experience, and has a lower design cost.

[0106] like Figure 7 As shown, according to some embodiments of the present application, the electronic device may further include a bearing 150 .

[0107] In this embodiment, the driving device 130 is fixedly connected to the electronic device via a bearing 150 . The bearing 150 is used to fix the driving device 130 , thereby fixing the cam mechanism 120 .

[0108] Continue to refer Figure 8 According to some embodiments of the present application, a power cord 160 is provided inside the bearing 150 , and the driving device 130 is electrically connected to the mainboard 140 through the power cord 160 .

[0109] During actual implementation, the control signal generated by the mainboard 140 is transmitted to the driving device 130 through the power line 160 , so that the driving device 130 drives the cam mechanism 120 to rotate based on the control signal.

[0110] Of course, in other embodiments, the driving device 130 and the mainboard 140 may be connected via wireless communication to reduce the number of wires and save space.

[0111] Continue to refer Figure 8 According to some embodiments of the present application, the electronic device may further include a frame 170 .

[0112] In this embodiment, an opening 190 is provided on the side of the frame 170 , and the cross-sectional area of ​​the opening 190 should not be less than the cross-sectional area of ​​the speaker 110 .

[0113] The speaker 110 is placed in the opening 190 , and the periphery of the speaker 110 is not connected to the edge of the opening 190 , so as to ensure that the speaker 110 can deflect freely in the opening 190 .

[0114] Continue to refer Figure 7 According to some embodiments of the present application, there are at least two speakers 110.

[0115] In this embodiment, at least two openings 190 are provided on the side of the frame 170 , and at least two speakers 110 are respectively disposed in the at least two openings 190 , and the at least two speakers 110 are disposed on the same side of the electronic device.

[0116] According to the electronic device of the embodiment of the present application, by providing at least two speakers 110, a dual-channel effect can be provided to improve the authenticity of the sound, which helps to improve the user experience.

[0117] The following combination Figure 9-10 , describes a control method of an electronic device according to an embodiment of the present application.

[0118] like Figure 9 As shown, the control method of the electronic device includes: step 910 and step 920.

[0119] Step 910: Obtain the location information of the target object;

[0120] In this step, the target object is an object to which directional sound transmission is required.

[0121] The location information is used to represent the location of the target object relative to the electronic device.

[0122] The location information may include: three-dimensional coordinate data, direction information of the target object relative to the electronic device, or relative location information of the target object relative to the electronic device, etc.

[0123] During actual execution, the location information of the target object may be obtained through a positioning device provided in the electronic device.

[0124] In some embodiments, step 910 may include:

[0125] Identify the facial information of the target object in the target area;

[0126] Determine location information based on facial information.

[0127] In this embodiment, the target area may be any area that can be covered by the sound waves of the speaker 110 .

[0128] During the actual execution process, facial information of the target object can be collected through an image sensor, and the facial information can include position data of the three-dimensional space corresponding to the face.

[0129] The position data in the three-dimensional space is determined as the position information of the target object.

[0130] According to the control method of the electronic device in the embodiment of the present application, the position information is determined based on the facial information of the target object, which can further narrow the positioning range and improve the positioning accuracy, so that the subsequent speaker 110 can accurately face the face direction of the target object rather than other directions, thereby further improving the effect of directional sound transmission.

[0131] Of course, in other embodiments, the location information may be determined in other ways.

[0132] For example, the sound waves of the target object are collected by a microphone, and then the position information of the target object is determined based on information such as the propagation direction or attenuation degree of the sound waves of the target object.

[0133] For example, the target object can be made to wear Bluetooth-related accessories (such as Bluetooth glasses) and the location information of the target object can be determined through Bluetooth positioning and other technologies; this application is not limited to this.

[0134] Step 920: Control the speaker 110 to rotate based on the position information.

[0135] In this step, after the position information of the target object is determined, the speaker 110 can be controlled to rotate toward the direction where the target object is located based on the position information to achieve directional sound transmission.

[0136] In some embodiments, step 920 may include:

[0137] Determine the target direction based on the position information;

[0138] The driving device 130 drives the cam mechanism 120 to rotate based on the target direction to drive the speaker 110 to rotate toward the target direction.

[0139] In this embodiment, the target orientation is the direction that the speaker 110 is intended to face.

[0140] For example, Figure 10 As shown, during normal operation of the electronic device, the positioning device in the electronic device determines the user's position information (such as the face position) and sends the position information to the main board 140;

[0141] The mainboard 140 determines a target orientation of the speaker 110 based on the position information, and generates a control instruction for adjusting the orientation of the speaker based on the target orientation;

[0142] The driving device 130 drives the cam mechanism 120 to rotate based on the received control instruction, so as to drive the speaker 110 to deflect toward the target direction.

[0143] Continue to refer Figure 10 In some embodiments, when the user's position changes, the mainboard 140 recognizes the change in the user's position, updates the position information, and adjusts the control instructions accordingly based on the updated position information to adjust the rotation of the driving device 130 and then adjust the deflection direction of the speaker 110, so that the speaker 110 can track the change in the user's position and change accordingly.

[0144] According to the control method of the electronic device in the embodiment of the present application, the rotation of the speaker 110 is controlled by the position information of the target object, so that the sound can be directionally transmitted to the direction corresponding to the user's position, which not only avoids the discomfort caused by the use of headphones, but also ensures the privacy of the sound, avoids sound pollution to others, and improves the user experience.

[0145] Continue to refer Figure 10 In some embodiments, before step 910, the method may include:

[0146] receiving a first input;

[0147] In response to the first input, a directional sound scene is entered.

[0148] In this embodiment, the first input is used to trigger and turn on the directional sound function.
