Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker and an integrated rubber edge sealing structure thereof. Background Art

[0002] A speaker is a transducer device that converts electrical signals into sound signals. The performance of the speaker has a great impact on the sound quality. In existing ordinary speakers, the frame and its internal components are usually installed on the outer shell first, and then a sealing ring is used to seal the connection between the frame and the outer shell.

[0003] The above-mentioned existing speakers use a rubber edge and a sealing ring that are set separately. Usually, the rubber edge is first installed on the basin frame, and then the rubber edge and the basin frame are installed on the shell, and finally the sealing ring is set on the rubber edge for sealing. In this arrangement, since the material of the rubber edge is relatively soft, the rubber edge is easily squeezed by the sealing ring and the basin frame and deformed, which causes the position of the diaphragm set on the rubber edge to shift, so that the cotton thread is easy to hit the diaphragm during the vibration process, which will generate noise, thereby affecting the overall sound effect of the speaker.

[0024] In one embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the integrated rubber edge sealing structure 10 includes: a rubber edge 100, a sealing ring 200 and a basin frame 300; the sealing ring 200 is arranged around the rubber edge 100, and the sealing ring 200 and the rubber edge 100 are integrally formed, and a sound outlet 110 is opened in the middle of the rubber edge 100, and the sound outlet 110 is used to place the diaphragm 500; the basin frame 300 has a cavity 310, the side wall of the sound outlet 110 is arranged in the cavity 310, and the sound outlet 110 is connected to the cavity 310, and the rubber edge 100 and the sealing ring 200 are both connected to the basin frame 300.

[0025] Specifically, by forming the rubber edge 100 and the sealing ring 200 in an integrated manner, when the rubber edge 100 and the basin frame 300 are installed on the housing, it is no longer necessary to install the sealing ring 200 at the connection between the basin frame 300 and the housing, thereby saving installation steps. At the same time, by forming the rubber edge 100 and the sealing ring 200 in an integrated manner, it is possible to prevent the rubber edge 100 from being deformed by the squeezing of the sealing ring 200 and the basin frame 300, thereby ensuring that the rubber edge 100 can maintain its existing shape, and further ensuring that the diaphragm 500 can be accurately arranged on the rubber edge 100, thereby preventing the diaphragm 500 from being hit by the cotton thread 400 during vibration and making noise, thereby ensuring that the speaker can sound normally without generating other noise.

[0026] In one embodiment, the rubber edge 100 and the sealing ring 200 are made of the same material, and the rubber edge 100 and the sealing ring 200 are integrally formed. The above configuration facilitates the production of the integrally formed rubber edge 100 and the sealing ring 200.

[0027] In order to accurately install the rubber edge 100 and the sealing ring 200 at the specified position of the basin frame 300, in one embodiment, as shown in FIG. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a mounting boss 320 is protrudingly provided on the basin frame 300, and the mounting boss 320 is connected to the sealing ring 200. Specifically, the mounting boss 320 is protrudingly provided at the edges of the basin frame 300, and the mounting boss 320 is protrudingly provided in the middle of the basin frame 300 to form a mounting groove 350. When the rubber edge 100 and the sealing ring 200 are installed on the basin frame 300, part of the rubber edge 100 will be located in the mounting groove 350 of the basin frame 300, and the sealing ring 200 is connected to the mounting boss 320. Through the above arrangement, the rubber edge 100 and the sealing ring 200 can be accurately installed on the basin frame 300.

[0028] In order to prevent the adhesive edge 100 from deforming, in one embodiment, Figure 2 As shown, a groove 210 is provided on the side of the sealing ring 200 facing the basin frame 300, and a gap 330 is provided between the mounting boss 320 and the rubber edge 100, and the groove 210 and the gap 330 are communicated. Specifically, by providing the groove 210 on the sealing ring 200, when the rubber edge 100 is installed, the gap 330 is left between the rubber edge 100 and the mounting boss 320, so that when the sealing ring 200 is installed on the basin frame 300, or when the sealing ring 200 is squeezed, the sealing ring 200 has a certain deformation space, and then the sealing ring 200 will only deform in the space of the groove 210 and the gap 330, so as not to affect the rubber edge 100, and ensure that the rubber edge 100 will not deform.

[0029] In one embodiment, Figure 4 As shown, the width of the groove 210 is equal to the width of the gap 330. Specifically, through the above configuration, the width of the groove 210 is equal to the width of the gap 330 to ensure that the sealing ring 200 has a suitable deformation space, thereby reducing the influence of the deformation of the sealing ring 200 on the rubber edge 100.

[0030] In order to ensure that the sealing ring 200, the rubber edge 100 and the basin frame 300 can be stably mounted on the housing, in one embodiment, Figure 1 and Figure 2 As shown, the sealing ring 200 is provided with a plurality of first mounting holes 220, and the first mounting holes 220 penetrate the sealing ring 200. The basin frame 300 is provided with a plurality of second mounting holes 340, and each first mounting hole 220 is aligned with and connected to a second mounting hole 340. Specifically, the second mounting hole 340 penetrates the basin frame 300. Through the above arrangement, bolts can be used to pass through the first mounting holes 220 and the second mounting holes 340 in sequence, and the bolts can be screwed to the housing, so that the sealing ring 200, the rubber edge 100 and the basin frame 300 can be stably mounted on the housing.

[0031] In one embodiment, Figure 2As shown, the aperture of the first mounting hole 220 is larger than the aperture of the second mounting hole 340. Specifically, the aperture of the first mounting hole 220 is larger than the width of the head of the bolt, and the aperture of the second mounting hole 340 is smaller than the width of the head of the bolt. Through the above arrangement, the threaded portion of the bolt can pass through the first mounting hole 220 and the second mounting hole 340 in sequence, so that the threaded portion of the bolt can be screwed with the side wall of the screw hole of the housing; and the head of the bolt will be stuck in the first mounting hole 220, so that the sealing ring 200, the rubber edge 100 and the basin frame 300 can be firmly installed on the housing through the bolt.

[0032] In one embodiment, Figure 3 and Figure 4 As shown, the rubber edge 100 has a folding ring portion 120, a connecting portion 130 and an opening portion 140, the first end of the folding ring portion 120 is connected to the opening portion 140, the sound outlet 110 is provided on the opening portion 140, the second end of the folding ring portion 120 is connected to the first end of the connecting portion 130, the second end of the connecting portion 130 is connected to the sealing ring 200, and the connecting portion 130 is provided with a buffer groove 131 at a position close to the folding ring portion 120. Specifically, by providing the buffer groove 131 on the connecting portion 130, the buffer groove 131 can effectively buffer the influence of the deformation of the sealing ring 200 on the rubber edge 100, thereby reducing the deformation of the opening portion 140 of the rubber edge 100, and further ensuring that the diaphragm 500 provided at the opening portion 140 can be in an accurate position, thereby preventing the diaphragm 500 from being hit by the cotton thread 400 during vibration.

[0033] In one embodiment, Figure 2 and Figure 4 As shown, the buffer groove 131 is an annular groove, and the buffer groove 131 is arranged around the folding ring portion 120. Specifically, by setting the buffer groove 131 in a circular ring shape, and surrounding the folding ring portion 120, the buffer groove 131 can better play a buffering role, fully protect the opening portion 140 of the rubber edge 100, and prevent the opening portion 140 from deformation.

[0034] In one embodiment, Figure 4As shown, the side wall of the buffer groove 131 close to the folding ring portion 120 is the first side wall 132, and the side wall of the buffer groove 131 arranged opposite to the first side wall 132 is the second side wall 133. The first side wall 132 is perpendicular to the bottom of the buffer groove 131, and the second side wall 133 is gradually inclined toward the sealing ring 200 from one end close to the bottom of the buffer groove 131 to one end away from the bottom of the buffer groove 131. Specifically, the first side wall 132 of the buffer groove 131 is perpendicular to the bottom of the buffer groove 131, and the second side wall 133 of the buffer groove 131 is inclined relative to the bottom of the buffer groove 131. Through the above arrangement, the second side wall 133 of the buffer groove 131 can more easily absorb the effect caused by the deformation of the sealing ring 200 when the sealing ring 200 is deformed, thereby better playing a buffering role.

[0035] In one embodiment, a speaker includes the integrated rubber edge sealing structure 10 described in any one of the above embodiments. Specifically, by providing the integrated rubber edge sealing structure 10 on the speaker, when installing the basin frame 300 and other components on the housing, it is only necessary to align the sealing ring 200 with the housing for installation, and no additional sealing ring 200 needs to be installed, thus saving installation steps. At the same time, by integrating the rubber edge 100 and the sealing ring 200, it is possible to prevent the rubber edge 100 from being deformed by being squeezed by the sealing ring 200 and the basin frame 300, thereby ensuring that the rubber edge 100 can maintain its existing shape, and further ensuring that the diaphragm 500 can be accurately set on the rubber edge 100, thereby preventing the diaphragm 500 from being hit by the cotton thread 400 during vibration and making noise, and ensuring that the speaker can make sound normally without generating other noise.
