[0029] In order to more clearly illustrate the technical solutions of the embodiments of this specification, the accompanying drawings required for the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some examples or embodiments of this specification. For those of ordinary skill in the art, without creative efforts, this specification can also be applied to other similar scenarios according to these drawings. Unless obvious from the language context or otherwise stated, the same reference numerals in the drawings represent the same structure or operation.

[0030] For the existing speaker to install the speaker mesh, it is necessary to install the speaker mesh on the mesh frame and then install the mesh frame on the speaker, which will result in additional connection structures. And in order to ensure that the speaker mesh will not sag and cause the problem of vibration, the speaker mesh needs to be kept flat. Since the speaker mesh cannot be adjusted after being connected to the mesh frame, when connecting the speaker mesh to the mesh frame, it is necessary to select an elastic material and make the speaker mesh in a tensioned state to ensure the flatness of the speaker mesh. This results in a small selection range of the speaker mesh and a high cost of the speaker mesh. And the speaker mesh can only cover the speaker opening, and the coverage range of the speaker mesh is limited, making it difficult to protect multiple sides of the speaker.

[0031] In view of this, in some embodiments of this specification, it is desired to provide an improved speaker, sleeving the speaker mesh on the side of the speaker, and fixing the speaker mesh to the speaker by using a bead to simplify the connection structure. And increase the coverage area of the speaker mesh on the speaker and increase the protection range of the speaker mesh.

[0032] Figure 1 It is an exploded structure schematic diagram of a speaker according to some embodiments of this specification. Figure 2 It is an overall structure schematic diagram of a speaker according to some embodiments of this specification. Figure 3 It is a connection schematic diagram of the bead and the box body according to some embodiments of this specification.

[0033] As Figure 1 、 Figure 2 shown, the speaker 10 may include a speaker mesh 130 and a box body 110. The speaker mesh 130 may be sleeved on the box body 110.

[0034] The cabinet 110 refers to the housing of the speaker 10. In some embodiments, a speaker may be mounted on the cabinet 110. For example, a speaker is mounted on one of the sides of the cabinet 110. In some embodiments, a signal conversion device may be provided inside the cabinet 110, and the signal conversion device may be used to convert an electrical signal into a sound signal. The signal conversion device may be connected to the speaker and transmit the sound signal to the speaker, causing the speaker to amplify and broadcast the sound signal.

[0035] In some embodiments, the cabinet 110 may include various shapes. For example, at least one of a prismatic shape, a cylindrical shape, etc.

[0036] In some embodiments, at least one mounting groove 111 is provided on the side surface of the cabinet 110.

[0037] The mounting groove 111 refers to a groove-shaped structure that is concave inward with respect to the side surface of the cabinet 110. In some embodiments, the length direction of the mounting groove 111 may be parallel to the length direction of the cabinet 110 (e.g., Figure 1 , Figure 2 the Z direction in

[0038] In some embodiments, when the cabinet 110 is prismatic, the mounting groove 111 may be provided at the corner of two adjacent side surfaces of the cabinet 110.

[0039] In some embodiments, at least a part of the speaker mesh 130 may be located inside the mounting groove 111.

[0040] In some embodiments, at least one pressing strip 120 is connected to the mounting groove 111.

[0041] The pressing strip 120 may include a strip-shaped structure. In some embodiments, the pressing strip 120 may press at least a part of the speaker mesh 130 into the mounting groove 111. In some embodiments, the length of the pressing strip 120 may be approximately equal to the length of the mounting groove 111.

[0042] For more information about the speaker mesh 130, please refer to the relevant description below.

[0043] In some embodiments, the pressing strip 120 and the mounting groove 111 may be connected in various ways. For example, at least one of snap connection, screw connection, etc.

[0044] In some embodiments, the depth of the bead 120 located in the mounting groove 111 can be adjusted, so as to exert different degrees of extrusion on the speaker mesh 130. This is beneficial to keep the speaker mesh 130 taut and flat, and avoid the phenomenon of vibration noise. In some embodiments, the bead 120 and the box body 110 can be connected by at least one screw 121. The screw 121 can pass through the bead 120 and be threadedly connected to the box body 110. By adjusting the screwing in or out of the screw 121, the depth of the bead 120 located in the mounting groove 111 can be adjusted. Using screws can improve the stability of the bead 120 and prevent the bead 120 from loosening.

[0045] In some embodiments, one or more mounting grooves 111 can be provided. For example, 2, 3 or more. When multiple mounting grooves 111 are provided, they can be evenly distributed in the circumferential direction of the box body 110. The number of beads 120 can be the same as the number of mounting grooves 111.

[0046] In some embodiments, the bead 120 can include at least one splicing unit, and multiple splicing units can be connected to each other. For example, end-to-end connection, etc. By connecting multiple splicing units, beads 120 of different lengths can be formed to adapt to mounting grooves 111 of different lengths. Ensure that the speaker mesh 130 in the mounting groove 111 can be compacted.

[0047] In some embodiments, multiple splicing units can be connected in various ways. For example, at least one of snap connection, clamping connection, threaded connection, etc. In some embodiments, multiple splicing units can include the same structure, so as to facilitate unified production, improve production efficiency and reduce production costs.

[0048] In some embodiments, the bead 120 can be connected to a housing (not shown in the figure).

[0049] The housing can cover and block at least part of the bead 120 and / or the box body 110. For example, covering the mounting groove 111 with the housing can prevent impurities such as dust and liquid from entering the mounting groove 111. In some embodiments, at least part of the outer surface of the housing can be arc-shaped, and at least part of the outer surface of the housing can be tangent to the side surface of the box body 110 to avoid forming sharp protrusions.

[0050] In some embodiments, the housing and the bead 120 can be connected in various ways. For example, at least one of snap connection, clamping connection, threaded connection, etc.

[0051] In some embodiments, as Figure 3 shown, at least one connecting protrusion 124 is provided on the outer side surface of the bead 120, and a connecting groove adapted to the connecting protrusion 124 can be provided on the housing. The connecting protrusion 124 can be snap-connected to the connecting groove. By adopting snap connection, the housing can be quickly loaded and unloaded conveniently.

[0052] The speaker grille cloth 130 can cover at least part of the outer surface of the cabinet 110. For example, it covers the side where the horn opening is located on the cabinet 110. In some embodiments, the speaker grille cloth 130 can be arranged in a ring shape circumferentially around the cabinet 110 to cover multiple sides of the cabinet 110, so as to enhance the protection effect of the speaker grille cloth 130 on the cabinet 110. In some embodiments, at least part of the speaker grille cloth 130 can extend beyond the end of the cabinet 110 along the length direction of the cabinet 110 (e.g., Figure 1 , Figure 2 the Z direction in

[0053] In some embodiments, the speaker grille cloth 130 can be made of a variety of materials. For example, elastic fabric or non-elastic fabric. Increasing the range of materials that the speaker grille cloth 130 can choose from enables the use of lower-cost materials to reduce the production cost of the speaker.

[0054] In some embodiments, at least one end of the cabinet 110 can be connected with an end cap. The end cap can be used to block and protect the end of the cabinet 110. In some embodiments, the end of the speaker grille cloth 130 can extend into the corresponding end cap.

[0055] For the speaker shown in some embodiments of this specification, pressing the speaker grille cloth into the installation groove by means of a pressing strip can eliminate the need for a mesh frame, which is beneficial to reducing the production cost and reducing the production process. And the depth of the pressing strip pressed into the installation groove can be used to control the tightness of the speaker grille cloth, thereby adjusting the flatness of the speaker grille cloth. The range of materials for the speaker grille cloth is large to reduce the use cost of the speaker grille cloth.

[0056] Figure 4 is a schematic structural diagram of the speaker grille cloth shown in some embodiments of this specification. Figure 5 is another schematic structural diagram of the speaker grille cloth shown in some embodiments of this specification.

[0057] In some embodiments, as Figure 4 shown, the speaker grille cloth 130 can be in a cylindrical shape. The speaker grille cloth 130 can be directly sleeved on the cabinet 110 and cover the side of the cabinet 110, which has the effect of convenient installation.

[0058] In some embodiments, the speaker grille cloth 130 can be made in a variety of ways.

[0059] In some embodiments, as Figure 4 shown, the speaker grille cloth 130 can be integrally formed with fabric.

[0060] In some embodiments, as Figure 5As shown, the speaker grille 130 can be made of at least one planar grille 131. When using a single grille 131, the opposite ends of the grille 131 are connected to curl the grille 131 into a cylindrical speaker grille 130. When using two or more grilles 131, the multiple grilles 131 are connected end to end in a ring to form a cylinder.

[0061] In some embodiments, a gap 133 can be reserved at the connection of the grille 131. When the pressure strip 120 and the cabinet 110 are connected by screws 121, the screws 121 can pass through the gap 133 to avoid damage to the grille 131 by the screws 121.

[0062] In some embodiments, the grille 131 can be connected in various ways. For example, at least one of bonding, stitching, etc. Among them, bonding can include bonding through at least one magic tape 132.

[0063] In some embodiments, the speaker grille 130 and the cabinet 110 can be connected by at least one pasting structure. This helps to improve the position accuracy of the speaker grille 130 relative to the cabinet 110 and increase the connection strength between the speaker grille 130 and the cabinet 110. It avoids phenomena such as wrinkles and damage to the speaker grille 130 caused by relative displacement between the speaker grille 130 and the cabinet 110.

[0064] In some embodiments, the pasting structure can include adhesive strips.

[0065] The adhesive strip refers to a strip structure with bonding ability. The adhesive strip can be made of an adhesive. For example, double-sided tape, etc.

[0066] In some embodiments, the adhesive strip can be disposed on at least one surface of the mounting groove. By using the adhesive strip, the speaker grille 130 and the mounting groove 111 can form a surface contact, which can improve the connection strength between the grille 130 and the cabinet 110. And a flexible connection is formed between the speaker grille 130 and the mounting groove 111. When the cabinet 110 undergoes thermal expansion and contraction, the influence of the thermal expansion and contraction of the cabinet 110 on the speaker grille 130 can be eliminated.

[0067] In some embodiments, the adhesive strip can be disposed at the corners of the cabinet 110. This further increases the connection strength between the speaker grille 130 and the cabinet 110.

[0068] Figure 6 It is another schematic structural diagram of the speaker grille according to some embodiments of this specification.

[0069] Figure 7 It is another schematic structural diagram of the speaker grille according to some embodiments of this specification.

[0070] Such as Figure 6 、Figure 7 As shown, at least one end of the speaker mesh 130 is provided with a contraction structure, and the contraction structure is configured to control the size of the end of the speaker mesh 130.

[0071] By reducing the opening size of the speaker mesh 130, when the end cap is connected to the box body 110, it can prevent the speaker mesh 130 from falling off and make the end of the speaker mesh 130 easier to be covered by the end cap.

[0072] In some embodiments, such as Figure 6 , Figure 7 As shown, the contraction structure includes an annular channel 134 and a contraction rope 135.

[0073] The annular channel 134 refers to a channel provided on the speaker mesh 130. The annular channel 134 can provide an installation space for the contraction rope 135 and play a certain restrictive role on the contraction rope 135 to prevent the contraction rope 135 from detaching from the speaker mesh 130.

[0074] In some embodiments, the annular channel 134 can be provided at the end of the speaker mesh 130 along the circumferential direction of the speaker mesh 130. In some embodiments, the annular channel 134 can be connected to the speaker mesh 130 in various ways. For example, at least one of integral forming, sewing, etc.

[0075] In some embodiments, at least a part of the contraction rope 135 can be threaded through the annular channel 134.

[0076] In some embodiments, such as Figure 6 As shown, the contraction rope 135 can be elastic. The contraction rope 135 can adopt an annular structure. The circumference of the contraction rope 135 in the natural state can be smaller than the circumference of the annular channel 134. When the contraction rope 135 is in the natural state, the contraction rope 135 can automatically reduce the end of the speaker mesh 130. When it is necessary to expand the opening at the end of the speaker mesh 130, the user can apply a pulling force to the contraction rope 135 to make the circumference of the contraction rope 135 larger, thereby loosening the end of the speaker mesh 130.

[0077] By adopting an elastic annular contraction rope, it is possible to automatically reduce the end of the speaker mesh, which has the advantage of convenient use.

[0078] In some embodiments, such as Figure 7 As shown, at least one inlet / outlet 136 can be provided on the annular channel 134. One end of the contraction rope 135 can enter the annular channel 134 from the inlet / outlet 136. When the contraction rope 135 passes through the annular channel 134, it leaves the annular channel 134 from the inlet / outlet 136. By simultaneously pulling out both ends of the contraction rope 135, the annular channel 134 can be tightened, thereby reducing the opening size of the end of the speaker mesh 130.

[0079] In some embodiments, after the ends of the speaker mesh 130 are narrowed, knots can be tied at both ends of the contraction rope 135, so that the ends of the speaker mesh 130 remain in a contracted state. In some embodiments, the two ends of the contraction rope 135 can also be connected by other means. For example, snaps, etc.

[0080] By adopting the annular channel and the contraction rope, the user can manually adjust the opening size of the end of the speaker mesh according to needs, which has the advantage of high flexibility.

[0081] In some embodiments, the pressure strip 120 is provided with a pressing portion.

[0082] The pressing portion refers to the structure that contacts the speaker mesh 130 and transmits pressure to the speaker mesh 130. In some embodiments, the pressure strip 120 applies pressure to the speaker mesh 130 through the pressing portion.

[0083] In some embodiments, the pressing portion and the speaker mesh 130 can be in contact in a variety of ways. For example, at least one of point contact, line contact, surface contact, etc.

[0084] In some embodiments, the projected area of the pressing portion on the speaker mesh 130 can be larger than the projected area of the pressure strip 120 on the speaker mesh 130. In this way, when ensuring that the speaker mesh 130 is effectively pressed, the size of the pressure strip 120 itself is small, which is beneficial to reducing the weight of the pressure strip and the production cost.

[0085] Figure 8 It is a schematic structural diagram of the pressure strip shown in some embodiments of this specification.

[0086] In some embodiments, as Figure 8 shown, the pressing portion can include at least two arc-shaped wing plates 140.

[0087] The arc-shaped wing plate 140 refers to a plate-like structure that extends outward relative to the side surface of the pressure strip 120. During the process of pressing the pressure strip 120 into the installation groove 111, the arc-shaped wing plate 140 contacts the speaker mesh 130 and transmits pressure to the speaker mesh 130, so that the speaker mesh 130 can be tensioned. In some embodiments, the arc-shaped wing plate 140 can be in contact or not in contact with the box body 110. In some embodiments, the arc-shaped wing plate 140 can be made of an elastic material. For example, at least one of rubber, spring steel, brass, etc.

[0088] In some embodiments, the sides of at least two arc-shaped wing plates 140 close to the speaker mesh 130 are concave arc surfaces. When the arc-shaped wing plates 140 are in contact with the box body 110, the pressing strip 120 can be continuously pressed. The arc-shaped wing plates 140 are deformed under pressure and continue to provide space for the movement of the pressing strip 120, so that speaker meshes 130 of larger sizes can be adapted, expanding the scope of application. It can also further enhance the elasticity of the arc-shaped wing plates 140.

[0089] In some embodiments, at least two arc-shaped wing plates 140 can be symmetrically distributed on both sides of the pressing strip 120. This is beneficial to expanding the coverage range of the arc-shaped wing plates 140 and enhancing the effect of the arc-shaped wing plates 140 in tensioning the speaker mesh 130.

[0090] In some embodiments, the pressing part can also include wing plates of other shapes. For example, flat wing plates and the like.

[0091] In some embodiments, the pressing part and the pressing strip 120 can be connected in various ways. For example, at least one of integral molding, detachable connection, etc. Among them, the detachable connection can include at least one of snap connection, threaded connection, etc.

[0092] In some embodiments, as Figure 8 shown, the pressing part includes a plurality of convex columns 150.

[0093] The convex column 150 refers to a columnar structure protruding relative to the structural surface. In some embodiments, a plurality of convex columns 150 can be arranged on the side of the pressing strip 120 close to the speaker mesh 130. When the pressing part applies pressure to the speaker mesh 130, the arc-shaped wing plates 140 are gradually deformed until the convex columns 150 come into contact with the speaker mesh 130. The convex columns 150 can increase the contact area and friction between the pressing part and the speaker mesh 130, and can play an anti-slip role. When the convex columns 150 are in contact with the box body 110, a part of the speaker mesh 130 is pressed on the box body 110 by the convex columns 150, and the stability of the speaker mesh 130 can also be improved, which is beneficial to preventing the speaker mesh 130 from loosening.

[0094] In some embodiments, through holes are provided at positions corresponding to the plurality of convex columns 150 on the pressing strip 120. That is, the through holes can penetrate the convex columns 150. By passing a plurality of screws 121 through the corresponding through holes, the pressing strip 120 is connected to the box body 110. Making the through holes correspond to the convex columns 150 can increase the surface area of the through holes, thereby increasing the projected area of the through holes on the screws 121, and can use the through holes to limit the partial rotational freedom of the screws 121, which is beneficial to aligning the screws 121 with the threaded holes on the box body 110.

[0095] In some embodiments, as Figure 3 shown, at least one guiding hole 122 is provided on the pressing strip 120.

[0096] The guiding hole 122 can be used to guide the screw 121 through the through hole on the pressing strip 120. In some embodiments, the guiding hole 122 and the protruding post 150 can be respectively located on opposite sides of the pressing strip 120. In some embodiments, the guiding hole 122 can be coaxially arranged with the protruding post 150. In some embodiments, the guiding hole 122 and the through hole can form a stepped hole, and at least part (such as the nut part, etc.) of the screw 121 cannot pass through the through hole.

[0097] In some embodiments, the guiding hole 122 can adopt an annular structure.

[0098] By adopting the guiding hole 122, before the screw 121 is connected to the box body 110, the screw 121 can be quickly positioned on the pressing strip 120 conveniently, and it is beneficial to prevent the screw 121 from loosening from the pressing strip 120. During the process of connecting the screw 121 to the box body 110, it can also provide support for at least part of the screw 121 to prevent the screw 121 from slipping.

[0099] Figure 9 It is a schematic structural diagram of a speaker mesh according to some embodiments of this specification.

[0100] In some embodiments, as Figure 9 shown, a plurality of mesh holes 136 for the screw 121 to pass through are provided on the speaker mesh 130. When the screw 121 is connected to the box body 110, the screw 121 can pass through the mesh hole 136 and be connected to the box body 110. It can prevent the screw 121 from piercing the speaker mesh 130, resulting in irregular wounds on the speaker mesh 130 and being easily damaged.

[0101] In some embodiments, as Figure 3 shown, a plurality of reinforcing ribs 123 are provided on the pressing strip 120.

[0102] The reinforcing ribs 123 can be used to increase the structural strength of the pressing strip 120. The pressing strip 120 can adopt a thin-walled structure, which is beneficial to reducing the materials used for manufacturing the pressing strip 120, thereby reducing the production cost.

[0103] In some embodiments, the reinforcing ribs 123 can be connected to the guiding hole 122. The reinforcing ribs 123 are used to support both the pressing strip 120 and the guiding hole 122 at the same time, increasing the strength of the overall structure of the pressing strip 120.

[0104] Figure 10 It is a schematic connection diagram of the installation groove and the pressing strip according to some embodiments of this specification.

[0105] As Figure 10As shown, slide rails 1111 can be provided on at least one surface of the installation groove 111, and sliding grooves 1211 adapted to the slide rails 1111 are provided on the pressure strip 120. The sliding grooves 1211 can be slidably engaged with the slide rails 1111. In some embodiments, the speaker mesh 130 can be disposed between the sliding grooves 1211 and the slide rails 1111, and the speaker mesh 130 is further clamped by the cooperation of the sliding grooves 1211 and the slide rails 1111.

[0106] In some embodiments, the cross-section of the slide rail 1111 can include various shapes. For example, at least one of an arc shape, a rectangular shape, etc. The cross-section of the sliding groove 1211 is adapted to the cross-section of the slide rail 1111.

[0107] In some embodiments, the slide rail 1111 can be made of an elastic material. For example, rubber, etc. When installing the pressure strip 120, the pressure strip 120 can be used to squeeze the slide rail 1111, causing the slide rail 1111 to undergo elastic deformation until the slide rail 1111 is aligned with the sliding groove 1211, and the slide rail 1111 returns to its original shape and forms a snap connection with the sliding groove 1211.

[0108] By using the cooperation of the sliding groove 1211 and the slide rail 1111, the rotational freedom and part of the translational freedom of the pressure strip 120 and the box body 110 can be restricted. When the end cover is connected to the box body 110, the end cover can restrict part of the translational freedom of the pressure strip 120 (for example, Figure 1 the freedom in the Z direction), so that the pressure strip 120 is kept fixed. In this way, the use of the screw 121 can be omitted, and the frequent rotation of the screw 121 can be avoided, making the use more convenient.

[0109] Figure 11 is another connection schematic diagram of the installation groove and the pressure strip shown according to some embodiments of this specification.

[0110] As Figure 11 shown, at least one side surface of the pressure strip 120 includes at least a partial cylindrical surface 125, and the installation groove 111 can be adapted to the cylindrical surface 125 of the pressure strip 120.

[0111] The pressure strip 120 can squeeze the speaker mesh 130 between the installation groove 111 and the pressure strip 120 through the cylindrical surface 125, thereby tensioning the speaker mesh 130. And the contact area between the speaker mesh 130 and the pressure strip 120 can be increased, thereby increasing the friction force between the speaker mesh 130 and the pressure strip 120 and preventing the phenomenon of slipping.

[0112] In some embodiments, the central angle corresponding to the contact surface between the installation groove 111 and the pressing strip 120 can be greater than 180°, which is beneficial to prevent the pressing strip 120 from detaching from the installation groove 111. In some embodiments, the central angle corresponding to the contact surface between the installation groove 111 and the pressing strip 120 can be less than 200°, which is beneficial to reduce the bending angle required for the speaker mesh 130 and is beneficial to prevent the speaker mesh 130 from being worn.

[0113] In some embodiments, the pressing strip 120 can be made of an elastic material. For example, at least one of rubber, silica gel, etc. This enables the pressing strip 120 to be snapped into the installation groove 111 from the opening of the installation groove 111 by utilizing its elasticity, which is beneficial to facilitate the installation of the pressing strip 120.

[0114] Figure 12 is another connection schematic diagram of the installation groove and the pressing strip shown according to some embodiments of this specification. Figure 13 is another connection schematic diagram of the installation groove and the pressing strip shown according to some embodiments of this specification.

[0115] As Figure 12 、 Figure 13 shown, the diameter of the installation groove 111 can be greater than the diameter of the cylindrical surface 125 of the pressing strip 120. A gap can be left between the installation groove 111 and the pressing strip 120. By adjusting the size of the gap between the installation groove 111 and the pressing strip 120, the tension of the speaker mesh 130 can be adjusted.

[0116] In some embodiments, the gap between the installation groove 111 and the pressing strip 120 can be adjusted in various ways.

[0117] In some embodiments, as Figure 12 shown, a screw 121 passing through the pressing strip 120 can be provided on the pressing strip 120, and the screw 121 can be threadedly connected to the installation groove 111. By screwing in or out the screw 121, the size of the gap can be adjusted.

[0118] In some embodiments, as Figure 13 shown, the pressing strip 120 can further include a clamping portion 126, and the cylindrical surface 125 is provided on one side of the clamping portion 126, and the cylindrical surface 125 can extend into the installation groove 111.

[0119] The clamping portion 126 can be made of an elastic material, and the width of the clamping portion 126 can be greater than the width of the opening of the installation groove 111, so that the clamping portion 126 can be stuck at the opening of the installation groove 111. When the gap needs to be adjusted, a pulling force or a pushing force can be applied to the clamping portion 126, thereby changing the size of the gap. In some embodiments, a part of the outer surface of the clamping portion 126 can be a cylindrical surface.

[0120] Figure 14It is another connection schematic diagram of the installation groove and the bead according to some embodiments of this specification.

[0121] In some embodiments, as Figure 14 shown, the bead 120 may include an elastic cylindrical structure. For example, a cylindrical structure made of rubber or silica gel. The diameter of the bead 120 may be greater than the width dimension of the installation groove 111. By using the elastic deformation of the bead 120, the speaker mesh cloth 130 can be clamped between the bead 120 and the installation groove 111. Thus, an additional connection structure can be saved, and the contact area and friction force between the bead 120 and the speaker mesh cloth 130 can be increased. The phenomenon of slipping can be avoided. By adjusting the depth of the bead 120 inserted into the installation groove 111, the tension degree of the speaker mesh cloth 130 can be adjusted. It has the advantages of a feasible usage scheme and reliable connection. The part of the bead 120 located outside the installation groove 111 may also form an arc-shaped protrusion, and the outer shell can be saved. This is beneficial to simplifying the structure.
