Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides electronic equipment. The electronic device may be a smart phone, a tablet computer, or other devices, and may also be a game device, an AR (Augmented Reality) device, an automobile, an audio playing device, a video playing device, a notebook computer, a desktop computing device, or other devices.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device 100 according to an embodiment of the present disclosure.

The electronic device 100 includes a housing 20 and a speaker assembly 40.

The housing 20 forms, among other things, the overall outline of the electronic device 100, as well as various electronic components and functional components for housing the electronic device 100. A speaker assembly 40 is mounted within the housing 20.

The speaker assembly 40 is used to generate sound and output the sound to the outside to implement a sound emission function of the electronic device 100. For example, the speaker assembly 40 may be used to convert an electrical signal into a sound signal to generate and output sound in a scene where a user makes a call, listens to music, watches video, plays games, and the like. It can be understood that the housing 20 may be provided with sound holes through which the speaker assembly 40 communicates with the outside, so that the sound generated by the speaker assembly 40 can be smoothly transmitted to the outside.

Referring to fig. 2 and 3 together, fig. 2 is a schematic perspective view of a speaker assembly 40 according to an embodiment of the present disclosure, and fig. 3 is a cross-sectional view of the speaker assembly 40 shown in fig. 2 along the direction M1-M2.

The speaker assembly 40 includes a cabinet 42, a speaker 44, a mover 46, and a driving device 48. The speaker 44 and the moving member 46 are connected to the cabinet 42, and the driving device 48 is connected to the moving member 46.

Cabinet 42 forms the overall outline of speaker assembly 40. The cabinet may also be referred to by other names such as speaker box. The material of the box 42 may include a material such as plastic. The case 42 may be integrally formed by injection molding or the like.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a cabinet 42 of a speaker assembly according to an embodiment of the present disclosure. Wherein case 42 includes side walls 422. Side walls 422 enclose a cavity 424, and cavity 424 may be a semi-enclosed space within cabinet 42. A through hole 426 is formed in the side wall 422, and the through hole 426 communicates with the cavity 424.

A speaker 44 is disposed within the cavity 424 and is coupled to the housing 42. For example, the speaker 44 may be fixed to the side wall 422 of the cabinet 42 by means such as screws, and the speaker 44 is located in the cavity 424 to close the opening of the cavity 424. Thus, a closed space can be formed in the cabinet 42 by the speaker 44. The sound generated by the speaker 44 can be transmitted to the outside through the cavity 424 and the through hole 426.

The mover 46 abuts against the side wall 422 of the casing 42. For example, the moving member 46 may abut the sidewall 422 and be disposed opposite the through-hole 426. Wherein, the moving element 46 is formed with a sound channel, and the sound channel can be used for sound transmission. The sound outlet passage may communicate with the through hole 426 to allow sound generated from the speaker 44 to be transmitted to the outside; the sound outlet channel may also be offset from the through-hole 426, so that the through-hole 426 is closed.

Wherein the mover 46 has a first state and a second state. The mover 46 is movable between a first state and a second state. For example, the mover 46 can rotate or slide between the first state and the second state. In the first state, the sound outlet passage of the moving member 46 communicates with the through hole 426, so that the cavity 424 of the case 42 communicates with the outside, and thus the sound can be transmitted to the outside. In the second state, the sound outlet passage of the moving member 46 is offset from the through hole 426, so that the cavity 424 of the casing 42 is isolated from the outside.

In the description of the present application, it is to be understood that terms such as "first", "second", and the like are used merely to distinguish one similar element from another, and are not to be construed as indicating or implying relative importance or implying any indication of the number of technical features indicated.

In some embodiments, referring to fig. 5, 6 and 7, fig. 5 is a first structural schematic diagram of the moving element 46 of the speaker assembly provided in the embodiment of the present application, fig. 6 is a second structural schematic diagram of the moving element 46 of the speaker assembly provided in the embodiment of the present application, and fig. 7 is a cross-sectional view of the moving element 46 shown in fig. 6 along a direction M3-M4.

The moving member 46 may be a rotor. The rotor 46 has an axis X about which the rotor 46 can rotate to go from the first state to the second state, or from the second state to the first state. Wherein rotor 46 includes an outer wall 462. The outer wall 462 encloses a cavity 464. The outer wall 462 has first 466 and second 468 spaced apart openings formed therein. The first opening 466, the cavity 464 and the second opening 468 are sequentially communicated to form a sound outlet channel on the moving member 46. It is understood that the first and

second openings

466, 468 may be one or more. For example, the first openings 466 may be 1 as shown in fig. 5, and the second openings 468 may be 4 as shown in fig. 6.

It will be appreciated that rotor 46 may be rotated about axis X to align or misalign first opening 466 with throughbore 426 of housing 42. When the first opening 466 is aligned with the through-hole 426, the first opening 466 communicates with the through-hole 426. Meanwhile, when the rotor 46 rotates around the axis X, the second opening 468 may be communicated with or separated from the outside.

In the first state, the first opening 466 is in communication with the through hole 426, and the second opening 468 is in communication with the outside, so that the cavity 424 on the box 42 is in communication with the outside, and the sound can be transmitted to the outside. In the second state, the first opening 466 is offset from the through-hole 426 and/or the second opening 468 is isolated from the outside, so as to isolate the cavity 424 on the casing 42 from the outside. It will be appreciated that in the second state, the first opening 466 is offset from the through-hole 426, so as to isolate the cavity 424 of the box 42 from the outside; second opening 468 may also isolate chamber 424 from the environment while isolating chamber from the environment; the first opening 466 may be offset from the bore 426 and the second opening 468 may be spaced from the exterior to isolate the cavity 424 in the housing 42 from the exterior.

In some embodiments, the surface of the outer wall 462 of the mover 46 is a smooth surface to prevent foreign substances such as dust from accumulating on the surface of the outer wall 462. Thus, even if the outer wall 462 of the moving member 46 is exposed to the outside, i.e., the outer wall 462 is in contact with the outside, the accumulation of the foreign objects on the outer wall 462 is not caused during the use of the electronic apparatus 100.

In practical applications, when the electronic device 100 needs to play sound, for example, in a scene where a user makes a call, listens to music, watches video, plays games, and the like, at this time, the speaker 44 enters the working mode, the electronic device 100 can control the rotor 46 to rotate to the first state, so that the first opening 466 is communicated with the through hole 426, and the second opening 468 is communicated with the outside, so that the cavity 424 on the box 42 is communicated with the outside, and thus the sound generated by the speaker 44 can be transmitted to the outside through the cavity 424, the through hole 426, the first opening 466, the cavity 464, and the second opening 468 in sequence, and therefore the electronic device 100 can normally output sound to the outside. It can be understood that, in practical applications, the time required for the electronic device 100 to play the sound is relatively short compared to the time required for not playing the sound, and the probability of foreign objects entering the electronic device is small. Furthermore, when the electronic device 100 plays the sound, the user is usually using the electronic device 100, so that the user can further avoid the external foreign object from entering the electronic device through the subjective processing of the user.

When the electronic device 100 does not need to play sound, for example, the electronic device 100 is in a standby state or a user uses the electronic device to browse a web page, watch an electronic novel, and the like, at this time, the speaker 44 exits from the operating mode, and the electronic device 100 may control the rotor 46 to rotate to the second state, so that the first opening 466 is staggered from the through hole 426 and/or the second opening 468 is separated from the outside, so as to separate the cavity 424 on the box 42 from the outside. At this time, since the electronic device 100 does not need to play sound, when the cavity 424 on the box 42 is isolated from the outside, the normal function of the electronic device 100 is not affected, and the external foreign object is prevented from entering the electronic device 100.

In some embodiments, referring to fig. 8, fig. 8 is a schematic structural diagram of a dust screen 48 of a speaker assembly according to an embodiment of the present disclosure.

The speaker assembly 40 also includes a dust screen 48, among other things. The dust screen 48 may be a net shape having a large number of small holes distributed therein so as to block foreign objects. The dust screen 48 is connected to the moving member 46 and is disposed opposite to the sound outlet passage of the moving member 46. Therefore, when the sound outlet channel is communicated with the outside, the dust screen 48 can prevent foreign objects from entering the electronic device 100, thereby improving the dust-proof effect of the electronic device 100.

With continued reference to fig. 6 and 7, the moving member 46 is provided with a mounting slot 470 therein. The mounting groove 470 is disposed opposite to the sound outlet channel of the moving member 46, for example, the mounting groove 470 is disposed opposite to the second opening 468. Wherein the dust screen 48 may be installed in the installation groove 470. For example, the dust screen 48 may be adhered to the wall of the mounting groove 470, i.e., the outer wall 462 of the moving member 46.

In some embodiments, with continued reference to fig. 2, a drive device 48 is coupled to the moving member 46. The driving device 48 is used for driving the moving member 46 to move between the first state and the second state. For example, when the moving member 46 is a rotor, the driving device 48 may be a motor. The driving device 48 is connected to the rotor 46 to drive the rotor 46 to rotate around the axis X. For example, when the driving device 48 is a motor, the motor may be fixedly connected to an end of the rotor 46, and when the motor rotates, the rotor 46 may be driven to rotate around the axis X.

For example, when the electronic device 100 needs to play sound and the speaker 44 enters the working mode, the processor of the electronic device 100 may send a first driving signal to the driving device 48, and the driving device 48 drives the moving element 46 to move to the first state according to the first driving signal. When the electronic device 100 does not need to play sound and the speaker 44 exits the operating mode, the processor of the electronic device 100 may send a second driving signal to the driving device 48, and the driving device 48 drives the moving element 46 to move to the second state according to the second driving signal.

Therefore, in the electronic device 100 provided in the embodiment of the present application, the moving element 46 is disposed in the speaker assembly 40, and the moving element 46 can move between the first state and the second state, so as to communicate or separate the cavity 424 inside the box 42 with the outside, thereby ensuring a normal sound generating function of the electronic device 100, and effectively avoiding external foreign objects from entering the electronic device 100 to block a sound channel, thereby improving a sound generating effect of the electronic device 100.

The speaker assembly and the electronic device provided by the embodiments of the present application are described in detail above. The principles and implementations of the present application are described herein using specific examples, which are presented only to aid in understanding the present application. Meanwhile, for those skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
