Description

Technical Field

[0001] The utility model relates to the technical field of speakers, and in particular to a microphone placement structure of an intelligent speaker. Background Art

[0002] A speaker is an electronic device that can produce sound, usually used to amplify and play audio signals. With the development of technology, simple sound playback speakers can no longer meet the needs of users, and speakers with microphones that can be used for karaoke have emerged.

[0003] Existing karaoke speakers come with a built-in microphone for user use. A storage structure is provided on the speaker body for the microphone, making it convenient to store it when not in use. Existing storage structures typically consist of a hole, into which the microphone is inserted. To place the microphone, align one end of the microphone with the hole and release it, allowing it to fall naturally. However, during this process, the microphone accelerates due to gravity. When it reaches the bottom of the hole, it collides with the bottom support with a strong force, producing a sound. This prevents silent placement of the microphone and can cause damage to the microphone, shortening its service life. Utility Model Content

[0044] One embodiment of the present invention proposes a microphone placement structure for a smart speaker, referring to Figure 1, including a sleeve assembly 2 for inserting a microphone 1, the sleeve assembly 2 being fixedly connected to the speaker box, and an elastic buffer assembly provided on the inner sidewall of the sleeve assembly 2 for contacting the surface of the microphone 1. The elastic buffer assembly includes a plurality of elastic members arranged along the length of the sleeve assembly 2. When the surface of the microphone 1 is covered with other structures (such as anti-slip fabric), the surface of the microphone 1 should be understood as the surface of the other structure on the surface of the microphone 1. It should be noted that this embodiment improves the microphone 1 placement structure of the existing speaker. An elastic buffer assembly is arranged on the inner wall of the sleeve assembly 2. When the microphone 1 is placed into the sleeve assembly 2, the side wall of the microphone 1 will abut against the elastic buffer assembly, and the outer wall of the microphone 1 squeezes the elastic buffer assembly to cause it to deform. Correspondingly, the elastic buffer assembly applies a reaction force to the outer wall of the microphone 1, thereby providing a certain friction force for the microphone 1 inserted into the sleeve assembly 2, decelerating and buffering it. At the same time, the elastic buffer assembly includes a number of elastic parts arranged along the length direction of the sleeve assembly 2, which can perform multi-level buffering and deceleration on the microphone 1, thereby effectively avoiding a large force collision between the end of the microphone 1 and the bottom of the sleeve assembly 2 at the moment the microphone 1 is installed in place, thereby avoiding damage to the microphone 1 and realizing silent placement of the microphone 1.

[0045] Specifically, the elastic member is configured as an annular protrusion 31 circumferentially arranged along the inner side wall of the sleeve assembly 2. In this embodiment, the elastic member is an annular protrusion 31 structure, and multiple annular protrusions 31 are evenly arranged along the length direction of the sleeve assembly 2. During the process of inserting the microphone 1 into the sleeve assembly 2, each annular protrusion 31 is squeezed in turn. Correspondingly, each annular protrusion performs multiple friction decelerations on the microphone 1 during the insertion process. In this way, by setting different numbers of annular protrusions 31, the movement speed of the microphone 1 at the moment before the microphone 1 is installed in place can be adjusted. Preferably, at the moment before the microphone 1 is installed in place, its speed is zero. In this embodiment, the number of annular protrusions 31 is set to three, and the three annular protrusions 31 are evenly arranged along the length direction of the sleeve assembly 2.

[0046] Specifically, the annular protrusion 31 is configured as a solid protrusion formed on the inner sidewall of the sleeve assembly 2. In this embodiment, the annular protrusion 31 is a solid structure, which has strong structural rigidity, a subtle deformation effect, and a high elastic force. Therefore, it exerts a greater contact force on the surface of the microphone 1, has a longer elastic fatigue life, and has a better deceleration effect on the microphone 1. In this embodiment, the annular protrusion 31 can be supported by an existing elastic material, such as silicone. The annular protrusion 31 can be formed separately from the inner sidewall of the sleeve assembly 2 or integrally formed with the sleeve assembly 2, without limitation.

[0047] refer to Figure 3, the annular protrusion 31 is configured as a concave structure formed on the outer wall of the sleeve assembly 2. In this embodiment, the annular protrusion 31 is a hollow structure, and its structural rigidity is weaker than that of a solid structure, but the deformation effect is obvious. Therefore, the abutting force applied to the surface of the microphone 1 is lower than that of the solid structure, which can better protect the microphone 1 and prevent its surface from being scratched, but its elastic fatigue life is lower than that of the solid structure. In this embodiment, the annular protrusion 31 can be supported by an existing elastic material, such as silicone, etc. The annular protrusion 31 can be molded separately on the inner wall of the sleeve assembly 2, or it can be integrally molded with the sleeve assembly 2, and there is no limitation here. Further, refer to Figure 4 The concave structure can also be arranged in a wave shape. The wave shape structure can increase the contact area between the annular protrusion 31 and the microphone 1, thereby wrapping the microphone 1 more stably.

[0048] It should be noted that, in the above two embodiments, the end portion of the annular protrusion 31 that is used to abut against the surface of the microphone 1 can be configured as a curved surface, thereby reducing the risk of scratching the surface of the microphone 1 .

[0049] Furthermore, the elastic member is configured as a plurality of protrusions 32 arranged circumferentially along the inner wall of the sleeve assembly 2. In this embodiment, the elastic member is a plurality of protrusions 32 arranged circumferentially along the inner wall of the sleeve assembly 2, and the connection line of each protrusion 32 forms a complete annular structure, and the protrusions 32 are arranged in groups, each group of protrusions 32 is arranged along a ring, and multiple groups of protrusions 32 are arranged along the length direction of the sleeve assembly 2; according to different forming methods, they can be arranged in a group horizontally, and the forming method can be formed by roller hot pressing with protrusions, or they can be arranged in a group vertically, such as Figure 6 As shown, the formation method can be formed by hot pressing a straight plate with convex points. This structure is simpler and saves materials compared to the continuous annular protrusion 31. Figure 2 In this embodiment, the head of the microphone 1 has a plurality of grooves 12, and each groove 12 extends in the circumferential direction. There are connecting members 11 between the grooves along the length direction of the microphone 1. If an elastic member in the shape of an annular protrusion 31 is used, when the user makes an error and installs the head downward, since there are connecting members 11 between the grooves 12 in the length direction (there is a part of continuity between two adjacent grooves), this structure can make the head of the microphone 1 more smoothly inserted into the sleeve assembly 2, and will not remind the user that the microphone 1 is placed upside down; if a convex point 32 structure is used, when the microphone 1 is placed in the right direction, the convex point 32 will engage with the grooves 12 on the head, which will provide the user with a continuous stuck feeling, thereby reminding the user that the microphone 1 is installed in the wrong direction.

[0050] Similarly, during the process of inserting the microphone 1 into the sleeve assembly 2, each group of protrusions 32 is squeezed in turn. Correspondingly, each group of protrusions 32 performs multiple friction decelerations on the microphone 1 during the insertion process. In this way, by setting different groups of protrusions 32, the movement speed of the microphone 1 at the moment before the microphone 1 is installed in place can be adjusted. Preferably, the speed of the microphone 1 is zero at the moment before the microphone 1 is installed in place. In this embodiment, the protrusions 32 are set to three groups, and the three groups of protrusions 32 are evenly arranged along the length direction of the sleeve assembly 2.

[0051] Furthermore, the protrusion 32 is configured as a solid protrusion formed on the inner sidewall of the sleeve assembly 2. Similarly, in this embodiment, the protrusion 32 is a solid structure, which has strong structural rigidity, a subtle deformation effect, but a high elastic force. Therefore, it exerts a greater contact force on the surface of the microphone 1, has a longer elastic fatigue life, and has a better deceleration effect on the microphone 1. In this embodiment, the protrusion 32 can be supported by an existing elastic material, such as silicone. The protrusion 32 can be formed separately on the inner sidewall of the sleeve assembly 2 or integrally formed with the sleeve assembly 2, without limitation.

[0052] Alternatively, refer to Figure 5 , the protrusion 32 is configured as a concave structure formed on the outer wall of the sleeve assembly 2. In this embodiment, the protrusion 32 is a hollow structure, and its structural rigidity is weaker than that of a solid structure, but the deformation effect is obvious. Therefore, the abutment force applied to the surface of the microphone 1 is lower than that of the solid structure, which can better protect the microphone 1 and prevent its surface from being scratched, but its elastic fatigue life is lower than that of the solid structure. In this embodiment, the protrusion 32 can be supported by existing elastic materials, such as silicone, etc. The protrusion 32 can be formed separately on the inner wall of the sleeve assembly 2, or it can be integrally formed with the sleeve assembly 2, and there is no restriction here. Specifically, the concave structure can be formed by existing injection molding, stamping, hot pressing, cold pressing and other forming methods. The wall thickness of the sleeve assembly should not be too thin, and the depth of the concave structure should not be too deep, otherwise it is easy to damage the sleeve assembly and fail to form a protrusion or annular protrusion. The wall thickness of the sleeve assembly should not be too thick, and the depth of the concave structure should not be too shallow, otherwise it will waste the internal space and material of the speaker. The value range of thickness a is 0.85~1.5mm, for reference Figures 8 to 10 The wall thickness of the sleeve assembly is set to a, the concave depth of the protrusion is set to b, and the end wall thickness of the protrusion is set to c, wherein the thickness a ranges from 0.85 to 1.5 mm, the depth b ranges from 1.5 to 2.5 mm, and the thickness c ranges from 0.35 to 1 mm. Preferably, the wall thickness of the sleeve assembly is set to thickness a = 1.2 mm, the concave depth of the protrusion is set to depth b = 2.3 mm, and the end wall thickness of the protrusion is set to thickness c = 0.5 mm.

[0053] It should be noted that, in the above two embodiments, the end of the protrusion 32 for abutting against the surface of the microphone 1 can be set to a curved surface, thereby reducing the risk of scratching the surface of the microphone 1 .

[0054] Further, refer to Figure 7 In this embodiment, the elastic buffer component is configured as an elastic layer covering the inner wall of sleeve assembly 2. This elastic layer can be made of existing elastic materials, such as silicone. The elastic layer can be molded separately from the inner wall of sleeve assembly 2 or integrally molded with sleeve assembly 2, without limitation. The thickness of the elastic layer gradually increases along the insertion direction of microphone 1. After the inner wall of sleeve assembly 2 is covered with the elastic layer, the aperture for inserting microphone 1 gradually decreases from the end to the bottom, thereby effectively buffering and decelerating microphone 1.

[0055] Further, refer to Figure 11 , an elastic support member 211 is provided at the bottom of the sleeve assembly 2, which abuts against the bottom of the microphone 1. In this embodiment, in order to further prevent the end of the microphone 1 from colliding with the bottom of the sleeve assembly 2, an elastic support member 211 is further added to the bottom of the sleeve assembly 2. Before the end of the microphone 1 is installed in place, it first abuts against the elastic support member 211, thereby achieving soft contact between the end of the microphone 1 and the bottom of the sleeve assembly 2, further buffering them, thereby achieving effective protection. In addition, the elastic support member 211 has a certain amount of interference and can absorb part of the abutting force through its own deformation, so that the end of the microphone 1 does not contact the main hard structure of the sleeve assembly 2, further reducing the risk of impact.

[0056] Furthermore, the elastic support member 211 is configured as a ring structure. In this embodiment, on the basis of simplifying the structure and saving materials, effective contact between the end face of the microphone 1 and the bottom of the sleeve assembly 2 is ensured. In this embodiment, the elastic support member 211 can be made of existing elastic materials, such as foam, without limitation.

[0057] Furthermore, an elastic support assembly 21 is further provided at the bottom of the sleeve assembly 2, and the elastic support member 211 is installed on the elastic support assembly 21. Figure 11 and Figure 12In this embodiment, the bottom of the sleeve assembly 2 is used to support the microphone 1 through an elastic support assembly 21, which can further cushion the microphone 1. The elastic support assembly 21 includes a support 212, which can elastically expand and contract along the length of the sleeve assembly 2. A spring 215 is mounted on its outer wall to achieve automatic reset. A swing arm 213 is mounted on the support 212 and moves up and down with the support 212. The sleeve assembly 2 can be provided with a fixed locking member 214, and the bottom of the locking member 214 is provided with a slot that engages with the swing arm 213. When the bracket 212 carries the microphone 1, it descends under the pressure of the microphone 1, and the swing arm 213 descends together with the bracket 212. The end of the swing arm 213 moves in contact with the surface of the locking piece 214, and moves from the first position in the figure to the second position. The swing arm 213 is limited, so that the position of the bracket 212 is fixed; when the microphone 1 needs to be taken out, it is only necessary to press the microphone 1 further, and the swing arm 213 continues to descend. After releasing the pressing force on the microphone 1, the swing arm 213 and the bracket 212 rise under the elastic restoring force of the spring 215, and the surface of the locking piece 214 of the swing arm 213 moves, and moves from the second position in the figure to the third position, contacting the lock of the swing arm 213 and the locking piece 214. The bracket 212 continues to rise under the action of the spring 215, pushing the microphone 1 out of the sleeve assembly 2, making it convenient for the user to take the microphone 1 away. In this example, the sleeve assembly 2 is inserted into the speaker. When the sleeve assembly 2 accommodates the microphone 1, an elastic bracket assembly 21 can be set under the sleeve assembly 2 to perform reciprocating motion. At this time, the microphone 1 can be locked and unlocked by pressing.

[0058] Further, refer to Figure 1 The sleeve assembly 2 includes an elastic sleeve 22 and a bracket sleeve 23 connected in sequence, and the elastic buffer assembly is disposed within the elastic sleeve 22. In this embodiment, the sleeve assembly 2 is configured as a split structure, wherein the elastic sleeve 22 is located at the front end of the sleeve assembly 2 and first contacts the microphone 1 when the microphone 1 is installed. Due to its elastic structure, it can prevent the microphone 1 from being inserted at an angle due to the user not being able to install the microphone 1 and the sleeve assembly 2 at the same axis, causing scratches between the microphone 1 and the sleeve assembly 2, thereby damaging the microphone 1. In this embodiment, the elastic sleeve 22 can be made of an existing elastic material, such as silicone, and this is not a limitation here.

[0059] The sleeve assembly 2 can be formed separately from the speaker panel and connected by plugging during assembly. In this case, the elastic sleeve 22 and the bracket sleeve 23 are internal and external structures (such as Figure 15 As shown), it can also be an upper and lower structure (elastic sleeve 22 on top); Figure 14 The sleeve assembly 2 can also be integrally formed with the upper plate of the speaker, in which case the elastic sleeve 22 and the bracket sleeve 23 are internal and external structures (such as Figure 15 As shown), it can also be an upper and lower structure (elastic member is at the bottom).

[0060] Furthermore, a fixing assembly is provided at the bottom of the sleeve assembly 2, which locks the microphone 1 when the end of the microphone 1 moves into the sleeve assembly 2. The fixing assembly can be a magnetic assembly. Specifically, a magnetic assembly can be provided at the bottom of the sleeve assembly 2, and a corresponding magnetic assembly can be provided at the microphone 1. When the microphone 1 is inserted, the magnetic assembly fixes the microphone 1. A finger groove 24 is provided at the insertion port of the sleeve assembly 2. When the microphone needs to be removed, it can be removed by grasping the microphone head.

[0061] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
