[0036] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0037] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0038] In this application, the term "and / or" describes the relationship between related objects, indicating that five relationships can exist. For example, A and / or B can represent five possibilities: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0039] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0040] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0041] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0042] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0043] like Figures 1 to 6As shown, this embodiment provides a speaker, which includes a support frame 100 and a protective cover 200. The support frame 100 has a front sidewall 110 extending vertically, and the front sidewall 110 is an arc shape protruding forward. The support frame 100 has a receiving cavity, and the front sidewall 110 has a front opening communicating with the receiving cavity. The protective cover 200 includes a transparent front panel 210, which is attached to the front sidewall 110 and covers the front opening of the receiving cavity.

[0044] The above configuration causes the front panel 210 to form a forward-convex structure when it is mounted on the support frame 100. This structure can be superimposed on the inward-convex visual effect it creates, so that from the outside, the front side wall 110 of the support frame 100 appears to be a flat structure. This improves the user experience, reduces the probability of complaints, and enhances the product's reputation.

[0045] In some embodiments, the height of the highest point of the front sidewall 110 ranges from 0.20 mm to 0.30 mm. For example, the protrusion height of the front sidewall 110 is 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, or 0.25 mm. In other embodiments, the protrusion height of the front sidewall 110 can be reasonably set according to the refractive index, length, width, and thickness of the front panel 210, as long as it ensures that the front sidewall 110 appears as a flat structure to the user from the outside.

[0046] The support frame 100 includes a left side wall 120 and a right side wall 130 arranged at intervals. One end of the front side wall 110 is connected to the left side wall 120, and the other end is connected to the right side wall 130. From the left side wall 120 to the right side wall 130, the height of the front side wall 110 first increases and then decreases, with a smooth transition. This arrangement makes the entire front side wall 110 relatively smooth and allows it to fit snugly against the front panel 210, improving connection stability. The support frame 100 also has a rear side wall 140 extending vertically and arranged opposite to the front side wall 110. The support frame 100 is cubic in shape.

[0047] In some embodiments, the protective cover 200 includes a left panel 220 and a right panel 230, with one end of the front panel 210 connected to the left panel 220 and the other end connected to the right panel 230; the included angle between the left side wall 120 and the right side wall 130 is a first angle; the front panel 210 is elastic, and the protective cover 200 has a first state before installation and a second state after installation. When the protective cover 200 is in the first state, the front panel 210 is a rearward-curved arc plate, and the included angle between the left panel 220 and the right panel 230 is a second angle, which is greater than the first angle; when the protective cover 200 is in the second state, the front panel 210 is attached to the front side wall 110 and bends backward; and the left panel 220 and the left side wall 120 are parallel and fixedly connected, and the right panel 230 and the right side wall 130 are parallel and fixedly connected. The above configuration allows the front panel 210 to remain in contact with the front side wall 110 through its own elasticity when the protective cover 200 is in the second state. Without mounting holes in the front panel 210, there will be no gap between the front panel 210 and the front side wall 110, which helps to improve the aesthetics of the speaker.

[0048] The left side wall 120 has a left opening communicating with the receiving cavity, and the right side wall 130 has a right opening communicating with the receiving cavity. The left panel 220 covers the left opening, and the right panel 230 covers the right opening. Both the left and right openings communicate with the front opening.

[0049] For example, the range of the second angle α is 15° to 25°. For example, the first angle is 0°, that is, the left side wall 120 and the right side wall 130 are parallel, and the second angle is 20°. In other embodiments, the first angle is 0°, and the second angle is 18°, 19°, 21°, or 22°. The specific angle can be determined by combining the distance between the left side wall 120 and the right side wall 130 and the elastic properties of the front panel 210, as long as it ensures that the front panel 210 does not break when it is attached to the front side wall 110.

[0050] To reduce the stress on the front panel 210, in some embodiments, the speaker also includes a buffer 300, which is sandwiched between the front panel 210 and the front sidewall 110 and surrounds the outer periphery of the front opening. The buffer 300 may be adhesive-backed, which can reduce the stress on the front panel 210 while also improving the connection strength.

[0051] In some embodiments, the left panel 220 has a left mounting hole 221, through which a left screw passes and is screwed into a left threaded hole 121 on the left side wall 120; the right panel 230 has a right mounting hole 231, through which a right screw passes and is screwed into a right threaded hole 131 on the right side wall 130. In other embodiments, the left panel 220 can be glued or snapped onto the left side wall 120, and the right panel 230 can be glued or snapped onto the right side wall 130.

[0052] To ensure reliable connection, specifically, the left panel 220 is provided with at least three left mounting holes 221, which are arranged at intervals along the vertical direction to reduce the probability of gaps appearing between the left panel 220 and the left side wall 120. Three left screws are provided, and they are arranged one-to-one with the three left mounting holes 221. (Reference) Figure 1 As shown, the vertical direction is the up-down direction.

[0053] Similarly, the right panel 230 is provided with at least three right mounting holes 231, which are arranged at intervals in the vertical direction to reduce gaps between the right panel 230 and the right side wall 130. Three right screws are provided, and they are arranged in a one-to-one correspondence with the three right mounting holes 231.

[0054] To further reduce the number of screws, in some embodiments, the left panel 220 is elastic and has a left mounting hole 221. The left mounting hole 221 is located at the end of the left panel 220 away from the front panel 210 and is vertically oriented. The left mounting hole 221 is located in the middle of the left panel 220. The left panel 220 has a third state and a fourth state. In the third state, the left panel 220 is an arc-shaped plate and bends away from the left side wall 120. In the fourth state, the left panel 220 is parallel to the left side wall 120. The above arrangement allows the left panel 220 to be flattened onto the left side wall 120 after the left screw in the middle is tightened. It should be noted that when the left panel 220 is in the third state, both the upper and lower corners away from the front panel 210 bend towards the left side wall 120.

[0055] The right panel 230 is elastic and has a right mounting hole 231 located at the end of the right panel 230 away from the front panel 210 and in a vertical direction. The right mounting hole 231 is located in the middle of the right panel 230. The right panel 230 has a fifth state and a sixth state. In the fifth state, the right panel 230 is an arc-shaped plate and bends away from the right side wall 130. In the sixth state, the right panel 230 is parallel to the right side wall 130. The above arrangement allows the two right screws in the middle to press the right panel 230 flat onto the right side wall 130 after tightening. It should be noted that when the right panel 230 is in the fifth state, both the upper and lower corners away from the front panel 210 bend towards the right side wall 130.

[0056] In other embodiments, the left panel 220 is elastic and has two left mounting holes 221. The left mounting holes 221 are located at the end of the left panel 220 away from the front panel 210 and are vertically oriented. The two left mounting holes 221 are spaced apart at both ends of the left panel 220. The left panel 220 has a third state and a fourth state. In the third state, the left panel 220 is an arc-shaped plate and bends towards the left side wall 120. In the fourth state, the left panel 220 is parallel to the left side wall 120. The above arrangement allows the left panel 220 to be flattened onto the left side wall 120 after the two left screws at both ends are tightened. It should be noted that when the left panel 220 is in the third state, both the upper and lower corners away from the front panel 210 are bent away from the left side wall 120.

[0057] The right panel 230 is elastic and has two right mounting holes 231. The right mounting holes 231 are located at the end of the right panel 230 away from the front panel 210 and are vertically aligned. The two right mounting holes 231 are spaced apart at both ends of the right panel 230. The right panel 230 has a fifth state and a sixth state. In the fifth state, the right panel 230 is an arc-shaped plate and bends towards the right side wall 130. In the sixth state, the right panel 230 is parallel to the right side wall 130. This arrangement allows the two right screws at both ends to be tightened, pressing the right panel 230 flat onto the right side wall 130. It should be noted that when the right panel 230 is in the fifth state, both the upper and lower corners away from the front panel 210 bend away from the right side wall 130.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
