Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, specifically to an electronic device. Background Technology

[0002] A speaker assembly is a transducer that converts electrical signals into sound signals, and its performance greatly affects sound quality. Currently, speaker assemblies in consumer electronics products such as mobile phones generally use a fixed-volume acoustic cavity. However, when playing different types of audio-visual products, the inability to adjust the cavity volume leads to poor audio playback. Summary of the Invention

[0003] This application provides an electronic device that can improve audio playback quality, the electronic device comprising:

[0004] Fixed body;

[0005] A movable body, slidably connected to a fixed body, allows the electronic device to have an extended state where the movable body and the fixed body are far apart, and a retracted state where the movable body and the fixed body are close together; and

[0006] A speaker assembly includes a housing, a movable component, and a speaker. The housing is fixed to a fixed body and has a receiving space. The speaker is received within the receiving space and divides the receiving space into a front acoustic cavity and a rear acoustic cavity. The movable component is at least partially housed within the receiving space. When the electronic device switches between an unfolded state and a retracted state, the movable component can move within the receiving space under the action of the movable body, causing a change in the volume of at least one of the front acoustic cavity and the rear acoustic cavity.

[0007] The electronic device provided in this application includes a fixed body, a movable body, and a speaker assembly. The movable body is slidably connected to the fixed body, and the speaker assembly is mounted on the fixed body. When the electronic device switches between an unfolded state and a retracted state, the movable component in the speaker assembly can move with the movable body, thereby changing the volume of at least one of the front and rear acoustic cavities. Therefore, the acoustic cavity size of the electronic device provided in this application is adjustable. When the electronic device plays different types of audio-visual products, the size of the acoustic cavity can be adjusted according to the characteristics of the audio, thereby achieving a better audio playback effect.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] Please refer to Figure 1 and Figure 2 This application provides an electronic device 100, which may be, but is not limited to, a mobile phone (such as a slider phone), a tablet computer, a laptop computer, a monitor, a display screen, a television, an electronic badge, a speaker, etc. The embodiments in this application are illustrated using a mobile phone as an example.

[0029] For ease of explanation later, a spatial rectangular coordinate system XYZ is defined here, where the X-axis is parallel to the width direction of the electronic device 100, the Y-axis is parallel to the length direction of the electronic device 100, and the Z-axis is parallel to the thickness direction of the electronic device 100. The direction pointed to by the arrow on the X-axis is the positive X-axis, and the opposite direction is the negative X-axis. Please refer to this for the following description of the coordinate system.

[0030] It should be noted that the length and width of the aforementioned electronic device 100 are not distinguished by size. That is to say, the length of the electronic device 100 can be greater than or less than the width, and this application does not limit this.

[0031] Please refer to Figures 1 to 4 The electronic device 100 includes: a fixed body 10, a movable body 20, and a speaker assembly 30, which will be described below with reference to the accompanying drawings.

[0032] The movable body 20 is slidably connected to the fixed body 10, so that the electronic device 100 has an unfolded state in which the movable body 20 and the fixed body 10 are far apart from each other (see...). Figure 2 ) and the retracted state in which the movable body 20 and the fixed body 10 are close to each other (see Figure 1 In other words, when the electronic device 100 is in the unfolded state, the movable body 20 and the fixed body 10 are far apart from each other, and when the electronic device 100 is in the retracted state, the movable body 20 and the fixed body 10 are close to each other.

[0033] The loudspeaker assembly 30 includes a housing 31, a movable component 32, and a loudspeaker 33 (see...). Figures 3 to 4 The housing 31 is fixed to the fixed body 10 and has a receiving space Y1. The speaker 33 is received within the receiving space Y1 and divides the receiving space Y1 into a front acoustic cavity Y11 and a rear acoustic cavity Y12. The movable component 32 is at least partially housed within the receiving space Y1. When the electronic device 100 switches between the unfolded state and the retracted state, the movable component 32 can move within the receiving space Y1 under the action of the movable body 20, causing a change in the volume of at least one of the front acoustic cavity Y11 and the rear acoustic cavity Y12.

[0034] Specifically, the fixed body 10 and the movable body 20 slide together, allowing the electronic device 100 to be in an unfolded state and a retracted state. When the electronic device 100 is in the unfolded state, its width in the X-axis direction is H1. When the electronic device 100 is in the retracted state, its width in the X-axis direction is H2. Wherein, H1 > H2. During the transition between the unfolded and retracted states, the width of the electronic device 100 changes between H1 and H2. Optionally, the electronic device 100 can maintain a shape between the unfolded and retracted states; that is, the width of the electronic device 100 can be maintained at H3, where H3 satisfies H1 > H3 > H2.

[0035] Illustrated from another perspective: the movable body 20 has a first accommodation space X1, and the first accommodation space X1 is configured to accommodate at least a portion of the fixed body 10. When the electronic device 100 is in the unfolded state, the volume of the fixed body 10 accommodated in the first accommodation space X1 is V1. When the electronic device 100 is in the folded state, the volume of the fixed body 10 accommodated in the first accommodation space X1 is V2. Wherein, V1<V2. During the mutual conversion between the unfolded state and the folded state of the electronic device 100, the volume of the fixed body 10 accommodated in the first accommodation space X1 changes between V1 and V2.

[0036] Further, the fixed body 10 has a second accommodation space X2, and the speaker assembly 30 is disposed in the second accommodation space X2. The speaker assembly 30 is composed of at least a housing 31, a movable component 32 and a speaker 33. Wherein, the housing 31 is fixedly connected to the fixed body 10, and the fixing method can be, but is not limited to, bonding, clamping, buckling, etc., or connection via a connecting member (screw, etc.). The housing 31 has an accommodation space Y1, and the accommodation space Y1 is configured to accommodate the movable component 32 and the speaker 33. The movable component 32 abuts against a side wall of the accommodation space Y1, so that the accommodation space Y1 becomes a closed space. The speaker 33 is disposed in the closed space and divides the closed space into a front acoustic cavity Y11 and a rear acoustic cavity Y12.

[0037] During the conversion between the unfolded state and the folded state of the electronic device 100, the movable body 20 can drive the movable component 32 to move. That is, when the movable body 20 moves along the negative X-axis direction, the movable component 32 can move along the negative X-axis direction following the movable body 20; when the movable body 20 moves along the positive X-axis direction, the movable component 32 can move along the positive X-axis direction following the movable body 20. It can be understood that the movement of the movable component 32 means that the volume of the aforementioned closed space changes, that is, the volume of at least one of the front acoustic cavity Y11 and the rear acoustic cavity Y12 changes. In one embodiment, when the movable component 32, the housing 31 and the speaker 33 together form the front acoustic cavity Y11, the movement of the movable component 32 will change the volume of the front acoustic cavity Y11. In another embodiment, when the movable component 32, the housing 31 and the speaker 33 together form the rear acoustic cavity Y12, the movement of the movable component 32 will change the volume of the rear acoustic cavity Y12. The composition of the front acoustic cavity Y11 and the rear acoustic cavity Y12 will be specifically described in subsequent embodiments.

[0038] Further, switching between the folded state and the unfolded state of the electronic device 100 can be implemented manually or driven by electronic control, which is not limited in the present application.

[0039] Further, the contour of the side wall forming the accommodation space Y1 in the housing 31 can be substantially rectangular, circular, trapezoidal, or the like.

[0040] Furthermore, the number of speaker assemblies 30 can be one or more, where "multiple" means two or more. It is understood that providing multiple speakers 33 enables the electronic device 100 to have a stereo effect. For example... Figure 5 As shown, two speaker assemblies 30 can be provided, and the two speaker assemblies 30 are spaced apart at both ends of the fixed body 10 along the Y-axis direction.

[0041] In summary, the electronic device 100 provided in this application includes a fixed body 10, a movable body 20, and a speaker assembly 30. The movable body 20 is slidably connected to the fixed body 10, and the speaker assembly 30 is mounted on the fixed body 10. When the electronic device 100 switches between an unfolded state and a retracted state, the movable component 32 in the speaker assembly 30 can move with the movable body 20, thereby changing the volume of at least one of the front acoustic cavity Y11 and the rear acoustic cavity Y12. When the electronic device 100 plays different types of audio-visual products, the size of the acoustic cavity volume can be adjusted according to the characteristics of the audio, thereby achieving the best audio playback effect.

[0042] Please refer to Figures 1 to 4 The electronic device 100 also includes a display screen 50, which is supported by the fixed body 10 and the movable body 20. One end of the display screen 50 is fixed to the fixed body 10, and the other end of the display screen 50 is slidably connected to the movable body 20. That is, during the transition between the retracted and extended states of the electronic device 100, the display screen 50 will slide along the surface of the movable body 20, thereby changing the display area on one side of the electronic device 100. Specifically, the display screen 50 has a display surface 51 for displaying images (see...). Figure 1 and Figure 2 The electronic device 100 has a first side C1 and a second side C2 (see...). Figure 3 and Figure 4 When the electronic device 100 is in the retracted state, a portion of the display surface 51 is located on the first side C1, and a portion of the display surface 51 is located on the second side C2, with the area of ​​the display surface 51 on the first side C1 being S1. As the electronic device 100 transitions from the retracted state to the unfolded state, at least a portion of the display screen 50 located on the second side C2 gradually slides to the first side C1, causing the area of ​​the display surface 51 on the first side C1 to gradually increase. When the electronic device 100 is fully unfolded, the area of ​​the display surface 51 located on the first side C1 is S2, where S2 > S1.

[0043] Furthermore, the fixed body 10 has a sound outlet, which connects to the front sound cavity Y11 and is used to emit sound. It should be noted that, depending on actual needs, the sound outlet can be located on any side of the electronic device 100, and this application does not limit this. Taking a mobile phone as an example, the sound outlet can be located on the front, back, or side of the phone. Here, the front refers to the side of the phone with the display screen 50; the back refers to the side of the phone with the battery cover; and the side refers to the circumferential side of the phone. It is understood that the definitions of front, back, and side may differ depending on the type of electronic device 100; other types of electronic devices 100 will not be detailed here.

[0044] The following section, with reference to the accompanying diagrams, introduces three different configurations of the front acoustic cavity Y11 and the rear acoustic cavity Y12.

[0045] In the first implementation method, please refer to Figure 6 and Figure 7 The speaker 33 and the housing 31 together form the front acoustic cavity Y11 with a fixed volume. The movable component 32, the housing 31, and the speaker 33 together form the rear acoustic cavity Y12. When the movable component 32 moves with the movable body 20, the volume of the rear acoustic cavity Y12 changes.

[0046] Specifically, the housing 31 includes a main body 311 and a supporting part 312 connected to each other. The main body 311 constitutes the receiving space Y1. The main body 311 has a first side L1 and a second side L2, which are the sidewalls of the receiving space Y1. The supporting part 312 protrudes from the second side L2 and is spaced apart from the first side L1. The speaker 33 is supported on the supporting part 312. The movable component 32 always abuts against the first side L1 and the second side L2. The main body 311, the supporting part 312, and the speaker 33 together constitute a solid-volume front acoustic cavity Y11. The main body 311, the supporting part 312, the speaker 33, and the movable component 32 together constitute a variable-volume rear acoustic cavity Y12. During the movement of the movable body 20 along the positive X-axis, the movable component 32 moves away from the speaker 33 under the action of the movable body 20, and the volume of the rear acoustic cavity Y12 increases; during the movement of the movable body 20 along the negative X-axis, the movable component 32 moves closer to the speaker 33 under the action of the movable body 20, and the volume of the rear acoustic cavity Y12 decreases.

[0047] Generally, the size of the front acoustic cavity Y11 primarily affects the high-frequency range of the sound quality, while the size of the rear acoustic cavity Y12 primarily affects the low-frequency range. Within certain limits, the larger the rear acoustic cavity Y12, the more prominent the low frequencies, the wider the mid-frequency range, the louder the sound, and the better the bass. Currently, to meet user demands, many electronic products are designed with high performance and thinness in mind, resulting in limited space for the speaker assembly 30. Consequently, the size of the rear acoustic cavity Y12 is generally quite limited, leading to less than ideal low-frequency sound quality. In this embodiment, the size of the rear acoustic cavity Y12 can change with the movement of the movable body 20, thereby effectively improving the problem of unsatisfactory low-frequency sound in existing products.

[0048] Of course, in other embodiments, the positions of the front acoustic cavity Y11 and the rear acoustic cavity Y12 can also be interchanged. That is, the speaker 33 and the housing 31 together constitute the rear acoustic cavity Y12 with a fixed volume. The movable component 32, the housing 31, and the speaker 33 together constitute the front acoustic cavity Y11. When the movable component 32 moves with the movable body 20, the volume of the front acoustic cavity Y11 changes. In this embodiment, to interchange the positions of the front acoustic cavity Y11 and the rear acoustic cavity Y12, it is only necessary to flip the speaker 33 so that the sound-emitting surface of the speaker 33 and the movable component 32 together constitute the front acoustic cavity Y11, thereby making the volume of the front acoustic cavity Y11 variable. For other structural configurations, please refer to the corresponding examples. Figure 7 The corresponding implementation methods will not be described in detail here.

[0049] In the second implementation method, please refer to Figure 8 Both the front acoustic cavity Y11 and the rear acoustic cavity Y12 are jointly constituted by the speaker 33, the housing 31, and the movable component 32. When the movable component 32 moves with the movable body 20, the volumes of the front acoustic cavity Y11 and the rear acoustic cavity Y12 change, and the trends of change are opposite.

[0050] Specifically, the housing 31 includes a main body 311 and a supporting part 312 connected to each other. The main body 311 has a first side L1, a second side L2, a third side L3, and a fourth side L4 that are sequentially bent and connected to form the sidewall of the receiving space Y1. The supporting part 312 is disposed between the first side L1 and the second side L2 and spaced apart from the first side L1 and the second side L2. The supporting part 312 includes a first sub-part 3121 and a second sub-part 3122. The first sub-part 3121 is disposed between the third side L3 and the fourth side L4 and is spaced apart from the third side L3 and the fourth side L4, respectively. The second sub-part 3122 is connected to the fourth side L4 and is spaced apart from the first sub-part 3121. The speaker 33 is supported on the first sub-part 3121 and the second sub-part 3122. The movable component 32 is always in contact with the first side L1 or the second side L2 of the first sub-part 3121 and the main body 311. That is, the movable component 32 can be located between the first side L1 and the first sub-part 3121, or between the second side L2 and the first sub-part 3121. Furthermore, both the front acoustic cavity Y11 and the rear acoustic cavity Y12 are composed of the speaker 33, the movable component 32, the main body 311, the first sub-part 3121, and the second sub-part 3122. It is understood that in this embodiment, when the movable component 32 moves away from or closer to the speaker 33 under the action of the movable body 20, the volumes of both the front acoustic cavity Y11 and the rear acoustic cavity Y12 will change, and the trends of volume change are opposite. That is, when the volume of the front acoustic cavity Y11 increases, the volume of the rear acoustic cavity Y12 decreases, and when the volume of the front acoustic cavity Y11 decreases, the volume of the rear acoustic cavity Y12 increases.

[0051] In the third implementation method, please refer to Figure 9 The movable component 32 includes a first sub-component 321 and a second sub-component 322. Both the first sub-component 321 and the second sub-component 322 can move under the drive of the movable body 20. The first sub-component 321, the housing 31, and the speaker 33 together constitute the rear acoustic cavity Y12. The second sub-component 322, the housing 31, and the speaker 33 together constitute the front acoustic cavity Y11. When the first sub-component 321 and the second sub-component 322 move with the movable body 20, the volumes of the front acoustic cavity Y11 and the rear acoustic cavity Y12 both change, and the change trends are the same.

[0052] Specifically, the housing 31 includes a main body 311 and a supporting part 312 connected to each other. The main body 311 has a first side L1, a second side L2, and a fourth side L4 that are bent and connected in sequence and form the sidewall of the receiving space Y1. The supporting part 312 is disposed between the first side L1 and the second side L2 and spaced apart from the first side L1 and the second side L2. The supporting part 312 includes a first sub-part 3121 and a second sub-part 3122 spaced apart. The first sub-part 3121 is spaced apart from the fourth side L4, and the second sub-part 3122 is disposed on the side of the first sub-part 3121 near the fourth side L4 and is connected to the fourth side L4. The speaker 33 is supported on the first sub-part 3121 and the second sub-part 3122. The first sub-part 321 always abuts against the first side L1 and the first sub-part 3121. The second sub-part 322 always abuts against the second side L2 and the second sub-part 3122. When the movable body 20 moves along the positive or negative X-axis, the first sub-component 321 and the second sub-component 322 can move along with the movable body 20, and the volumes of the front acoustic cavity Y11 and the rear acoustic cavity Y12 change accordingly, and the volumes increase or decrease simultaneously.

[0053] It should be noted that in the above three implementation methods ( Figures 7 to 9 The positions of the front acoustic cavity Y11 and the rear acoustic cavity Y12 (as shown in the diagram) can be interchanged. The markings in the diagram are merely illustrative and should be determined according to actual design requirements. This application does not limit the specific implementation. It is understood that in addition to the three different implementation methods described above, there are other feasible implementation methods, which will not be detailed here.

[0054] The following description is based solely on the structure given in the first embodiment described above. Without contradiction, the features described below can also be applied to the second and third embodiments described above.

[0055] The connection relationship between the active component 32 and the active body 20 is described below with reference to the accompanying drawings.

[0056] In one implementation, please refer to Figure 3 and Figure 4The movable component 32 is fixedly connected to the movable body 20. Therefore, during the transition between the unfolded and retracted states of the electronic device 100, the movable component 32 and the movable body 20 will move synchronously, with the same stroke, and there will be no relative movement. Optionally, the movable body 20 includes a movable frame 21, which includes a plate-shaped portion 211 and a columnar portion 212, with the columnar portion 212 connected to one side of the plate-shaped portion 211. The plate-shaped portion 211 is spaced apart from the speaker assembly 30. When the electronic device 100 is in the retracted state, the columnar portion 212 is close to the fixed body 10; when the electronic device 100 is in the unfolded state, the columnar portion 212 is away from the fixed body 10. The movable component 32 has a first end D1 and a second end D2 that are opposite to each other (see...). Figure 7 In this configuration, the first end D1 is always located within the receiving space Y1 of the housing 31, and the second end D2 is fixedly connected to the columnar portion 212. The fixed connection between the second end D2 and the columnar portion 212 can be, but is not limited to, adhesive bonding, snap-fitting, or fastening, or can be achieved through connectors (screws, etc.). It is understood that fixing the movable component 32 to the columnar portion 212 maximizes the travel of the movable body 20 relative to the fixed body 10, thereby maximizing the area of ​​the display surface 51 located on the first side C1.

[0057] In another implementation, please refer to Figure 10 The movable component 32 and the movable body 20 are movable relative to each other. Therefore, the travel distances of the movable component 32 and the movable body 20 are different during the transition between the unfolded and retracted states of the electronic device 100. Specifically, the movable body 20 includes a movable frame 21 and a limiting member 22. The movable frame 21 includes a plate-shaped portion 211 and a columnar portion 212. For a description of the plate-shaped portion 211 and the columnar portion 212, please refer to the previous embodiment. The columnar portion 212 of the movable frame 21 has a first surface M1 facing the speaker assembly 30. The limiting member 22 is connected to the plate-shaped portion 211 of the movable frame 21. The limiting member 22 also has a second surface M2 facing the first surface M1. The movable component 32 has a first end D1 and a second end D2 that are opposite to each other (see...). Figure 7 The first end D1 is always located within the receiving space Y1 of the housing 31. The second end D2 of the movable component 32 has a first abutment surface N1 and a second abutment surface N2 disposed opposite to each other and located between the first surface M1 and the second surface M2. The distance d1 between the first surface M1 and the second surface M2 is greater than the distance d2 between the first abutment surface N1 and the second abutment surface N2. The first abutment surface N1 abuts against the first surface M1, and the second abutment surface N2 abuts against the second surface M2.

[0058] It is understandable that, since d1>d2, the movable component 32 will have a free travel during the transition between the extended and retracted states of the electronic device 100. This free travel means that the movable component 32 will not move in tandem with the movable body 20. Specifically, when the electronic device 100 is in the retracted state, the first surface M1 abuts against the first contact surface N1. At this time, the second end D2 of the movable component 32 is close to the speaker 33, and the volume of the rear acoustic cavity Y12 is at its minimum. During the transition from the retracted state to the extended state (i.e., the movable body 20 moves in the positive X-axis direction), the first surface M1 first separates from the first contact surface N1. The movable component 32 remains stationary for a period of time until the second surface M2 of the limiting member 22 abuts against the second contact surface N2 of the movable component 32. In the subsequent process, the limiting member 22 pushes the movable component 32 to move in the positive X-axis direction until the electronic device 100 is fully extended, at which point the volume of the rear acoustic cavity Y12 is at its maximum. Similarly, during the process of the electronic device 100 changing from the unfolded state to the retracted state (i.e., the movable body 20 moving in the negative X-axis direction), the second surface M2 first separates from the second contact surface N2, and the movable component 32 remains stationary for a period of time until the first surface M1 of the columnar portion 212 abuts against the first contact surface N1 of the movable component 32. In the subsequent process, the columnar portion 212 pushes the movable component 32 to move in the negative X-axis direction until the electronic device 100 is completely converted to the retracted state. It should be noted that... Figure 10 The rear acoustic cavity Y12 in the diagram is merely an example and can be replaced by the front acoustic cavity Y11.

[0059] As described above, because the movable component 32 is not fixed to the movable body 20 and has a free travel, the movement range of the movable component 32 is less than that of the movable body 20. Therefore, compared to the above-mentioned solution of fixing the movable component 32 to the movable body 20, the solution of having a free travel for the movable component 32 can reduce the length of the movable component 32 and the housing 31 in the X-axis direction, thereby reducing the overall size of the speaker assembly 30 in the X-axis direction. It can be understood that a smaller size of the speaker assembly 30 means a smaller space occupied, thus reserving more space for other electronic components within the electronic device 100. Conversely, the above-mentioned solution of fixing the movable component 32 to the movable body 20 can make the speaker assembly 30 larger, thereby increasing the range of variation in the volume of the front acoustic cavity Y11 and the rear acoustic cavity Y12, and thus making it easier to find the acoustic cavity volume size suitable for the audio characteristics.

[0060] Optional, please refer to Figure 11The electronic device 100 also includes a buffer 80, which is fixed to the first surface M1 or the first contact surface N1. The buffer 80 absorbs the impact when the first surface M1 and the first contact surface N1 come into contact. That is, the first surface M1 and the first contact surface N1 indirectly contact each other through the buffer 80, thereby preventing a large impact between the movable component 32 and the movable body 20. It is understood that in some special circumstances, such as when the electronic device 100 is dropped, the movable body 20 may be subjected to a large external force and instantly come into contact with the movable component 32, resulting in a large impact between the two, which may damage the movable component 32, the movable body 20, or other components. The buffer 80 provided in this embodiment can weaken the impact, thereby helping to extend the lifespan of the electronic device 100. Of course, the buffer 80 can also be provided on the second surface M2 or the second contact surface N2 to absorb the impact force when the second surface M2 and the second contact surface N2 come into contact. The buffer 80 can be a spring, or it can be made of elastic materials such as rubber or silicone.

[0061] Optionally, the limiting member 22 is made of an elastic material (rubber, silicone, etc.), so that the limiting member 22 itself can absorb the impact force when the second surface M2 and the second contact surface N2 come into contact.

[0062] Optional, please refer to Figure 10 Reference Figure 12 The fixed body 10 has an outer surface R that faces away from the speaker assembly 30. The distance from the housing 31 of the speaker assembly 30 to the outer surface R is a first distance h1. The distance from the limiting member 22 to the outer surface R is a second distance h2, wherein the first distance h1 is greater than the second distance h2. To illustrate from the opposite perspective, it can be understood that as the electronic device 100 gradually transitions to a retracted state (i.e., the movable body 20 moves in the negative X-axis direction), the limiting member 22 gradually approaches the housing 31 of the speaker assembly 30. If h2 is greater than or equal to h1, the limiting member 22 will collide with the housing 31, preventing the movable body 20 from moving further. In this embodiment, h1 is set to be greater than h2, thereby avoiding the collision between the limiting member 22 and the housing 31, allowing the size of the electronic device 100 in the X-axis direction to be further reduced.

[0063] Please refer to Figure 13The movable component 32 includes a movable element 3211 and a sealing element 3222. The movable element 3211 is used to connect to the movable body 20. The sealing element 3222 is sleeved on the outer periphery of the movable element 3211 and abuts against the side wall of the receiving space Y1 to seal the receiving space Y1. That is, one side of the sealing element 3222 abuts against the side wall of the receiving space Y1, and the other side of the sealing element 3222 abuts against the surface of the movable element 3211, thereby sealing the gap between the movable element 3211 and the housing 31. The sealing element 3222 is a closed ring to ensure that a seal can be achieved in the circumferential direction of the movable element 3211. The sealing element 3222 may be elastic and elastically abuts against the housing 31 and the movable element 3211, thereby achieving a more effective seal. The material of the sealing element 3222 may be, but is not limited to, rubber.

[0064] Optionally, the movable part 3211 is provided with a recessed groove, and the sealing member 3222 is disposed in the recessed groove. This arrangement can prevent the sealing member 3222 from slipping off the movable part 3211 during the movement of the movable part 3211.

[0065] Please refer to Figures 14 to 15 The movable component 32 has a first mating part P1, and the housing 31 has a second mating part P2. The shapes of the first mating part P1 and the second mating part P2 are adapted to each other. During the movement of the movable component 32 relative to the housing 31, the first mating part P1 and the second mating part P2 remain engaged and connected. It is understood that in some special circumstances, such as when the electronic device 100 is dropped or impacted, the relative position of the movable component 32 and the housing 31 may become misaligned. After several movements, the movable component 32 may experience uneven wear, leading to a decrease or even failure of the sealing effect at the worn portion. In this embodiment, the first mating part P1 and the second mating part P2 are engaged and connected, thereby standardizing the relative positional relationship between the movable component 32 and the housing 31. Furthermore, during the movement of the movable component 32, the first mating part P1 and the second mating part P2 remain engaged and connected, ensuring that the relative positional relationship between the movable component 32 and the housing 31 is always maintained at the theoretical position, thus avoiding relative misalignment. Additionally, it ensures that the movement path of the movable component 32 is a straight line and parallel to the movement direction of the movable body 20.

[0066] The following describes several structural forms of the first mating part P1 and the second mating part P2.

[0067] In the first structural form, the first mating part P1 and the second mating part P2 are in a raised-groove type. Specifically, in one embodiment, please refer to... Figure 14In one embodiment, the first mating part P1 is a protrusion, and the second mating part P2 is a groove. The protrusion extends outward from the movable component 32, and the groove is located inside the housing 31, with the protrusion inserted within the groove. During the movement of the movable component 32 relative to the housing 31, at least a portion of the protrusion remains within the groove. In another embodiment, the first mating part P1 is a groove, and the second mating part P2 is a protrusion. The protrusion extends outward from the inner wall of the housing 31, and the groove is located on the outer side of the movable component 32, with the protrusion inserted within the groove. During the movement of the movable component 32 relative to the housing 31, at least a portion of the protrusion remains within the groove. In this first structural form, the groove can be, but is not limited to, a dovetail groove, a T-groove, etc.

[0068] In the second structural form, the first mating part P1 and the second mating part P2 are in a rod-hole mating type. In one embodiment, please refer to... Figure 15 In one embodiment, the first mating part P1 is rod-shaped, and the second mating part P2 has a mating hole P21. The first mating part P1 passes through the mating hole P21 of the second mating part P2, wherein the extension direction of the rod-shaped first mating part P1 is parallel to the movement direction of the movable body 20. In another embodiment, the second mating part P2 is rod-shaped, and the first mating part P1 has a mating hole P21. The second mating part P2 passes through the mating hole P21 of the first mating part P1, wherein the extension direction of the rod-shaped second mating part P2 is parallel to the movement direction of the movable body 20.

[0069] Of course, the first mating part P1 and the second mating part P2 can be other structural forms, which will not be described in detail here.

[0070] Please refer to Figure 5 The electronic device 100 further includes a drive assembly 40, which comprises a motor 41 and a driver 42. The motor 41 is fixed to the fixed body 10. The opposite ends of the driver 42 are respectively connected to the motor 41 and the movable body 20. The driver 42 can extend and retract under the drive of the motor 41 to drive the movable body 20 to move relative to the fixed body 10. That is, when the driver 42 extends, it pushes the movable body 20 away from the fixed body 10, and the electronic device 100 changes from a retracted state to an extended state. When the driver 42 retracts, it pulls the movable body 20 closer to the fixed body 10, and the electronic device 100 changes from an extended state to a retracted state. It can be understood that by controlling the switching between the retracted and extended states through the drive assembly 40, the movement of the movable component 32 in the speaker assembly 30 can be more precisely controlled, thereby more precisely adjusting the size of the acoustic cavity to adapt to the current audio characteristics.

[0071] Optional, please refer to Figure 16 The electronic device 100 further includes a controller 60 and a detector 70, the controller 60 being electrically connected to the detector 70 and the drive assembly 40. The detector 70 analyzes the characteristics of the current audio to generate an audio signal, which is then sent to the controller 60. In response to the audio signal, the controller 60 generates a control signal, which controls the drive assembly 40 to move the movable body 20. The movable body 20 then moves the movable assembly 32, causing the volume of the front acoustic cavity Y11 and / or the rear acoustic cavity Y12 to adapt to the current audio characteristics.

[0072] Optional, please refer to Figure 17 The speaker assembly 30 further includes an elastic element 34 made of an elastic material, which forms the front acoustic cavity Y11 and / or the rear acoustic cavity Y12. That is, at least one sidewall of the front acoustic cavity Y11 can be formed by the elastic element 34, and at least one sidewall of the rear acoustic cavity Y12 can also be formed by the elastic element 34 (e.g., Figure 17 (As described above). Because different audio qualities cause different vibration effects in the gas inside the acoustic cavity, the elastic element 34 expands and contracts differently under the influence of vibration waves, thereby achieving adaptive adjustment of the acoustic cavity volume to adapt to the current audio effect.

[0073] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application, and such improvements and refinements are also considered to be within the protection scope of this application.
