Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to a speaker mounting structure. Background Technology

[0002] A speaker is a device that converts audio signals into sound. A speaker typically includes a speaker housing and a horn installed inside the speaker housing. In the current technology, the horn can usually only emit sound in one direction of the speaker (such as in front of the speaker) and cannot emit sound in all directions of the speaker. This results in a narrow sound coverage and poor stereo effect, which cannot meet the surround sound field requirements of a conference setting.

[0003] With technological advancements, speakers capable of emitting sound in all directions have gradually emerged. See Chinese patent document CN119789002A, which discloses a speaker comprising a speaker housing, a speaker mounted within the housing, a platform connected to the top of the housing, and a ring of sound outlets arranged around the outer periphery of the platform. The speaker's sound output direction is upward, and the sound emitted by the speaker is output from the sound outlets on the outer periphery of the platform. Because the platform reflects sound waves, and the sound outlets are arranged in a ring around the outer periphery of the platform, this speaker can emit sound in all directions, providing good stereo sound and meeting the surround sound requirements of conference settings.

[0004] However, the speaker structure disclosed in the Chinese patent document CN119789002A has the following problems: (1) The speaker is directly installed inside the speaker housing. When the speaker makes a sound, it will vibrate, which will cause the speaker to loosen due to vibration. At the same time, when the speaker is loose, the sound cavity inside the speaker housing will leak air. When the sound cavity leaks air, it will directly reduce the sound effect of the speaker; (2) The speaker needs to be set with a more complex connecting ring. Multiple connecting holes are set on the connecting ring. Then, screws are passed through the connecting holes of the connecting ring and screwed into the speaker housing. The overall connection structure is more complex. When the speaker is installed, it needs to be processed twice. First, the connecting ring is assembled on the speaker, and then the connecting ring is installed inside the speaker housing. The assembly process is more cumbersome. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a speaker mounting structure for a speaker box. The speaker of this mounting structure can reflect sound waves to the outside of the speaker box, providing a good stereo effect and meeting the surround sound field requirements of conference scenarios. Furthermore, the speaker mounting structure can prevent the speaker from loosening and leaking due to vibration. The speaker mounting structure has high assembly efficiency, requiring no secondary processing and can be directly assembled in one step.

[0006] To solve the above technical problems, the technical solution of the present utility model is: a speaker mounting structure for a speaker, comprising a speaker lower housing, a speaker, a sealing ring, a speaker upper housing and a plurality of screws. There is a speaker inner cavity inside the speaker lower housing, and a speaker mounting opening is provided at the upper end of the speaker lower housing. An annular convex ring is provided on the inner wall of the speaker mounting opening. The outer edge portion of the speaker is mounted on the annular convex ring and the sound emitting direction of the speaker faces upward. The sealing ring is placed between the annular convex ring and the outer edge portion of the speaker. The speaker upper housing and the speaker lower housing are arranged at intervals, and there is a sound emitting opening for the speaker to emit sound between the speaker upper housing and the speaker lower housing. The speaker upper housing is connected with a plurality of connecting feet, and each connecting foot is provided with a connecting hole. A plurality of screw holes corresponding to the connecting holes are provided at the upper end of the speaker lower housing. The screws pass through the connecting holes and are screwed with the screw holes, so that the connecting feet are fixedly connected with the speaker lower housing. The connecting feet of the speaker upper housing simultaneously press on the outer edge portion of the speaker to firmly fix the speaker.

[0007] In the above technical solution, the sealing ring is an EVA sealing ring.

[0008] In the above technical solution, the speaker comprises a chassis and a paper cone mounted on the chassis. The outer edge portion of the chassis is mounted on the annular convex ring. The sealing ring is placed between the annular convex ring and the outer edge portion of the chassis. The connecting feet of the speaker upper housing simultaneously press on the outer edge portion of the paper cone.

[0009] In the above technical solution, the speaker upper housing is connected with 3 connecting feet. The 3 connecting feet are arranged in a "pin" shape, and the 3 connecting feet divide the sound emitting opening into 3 sound emitting opening parts.

[0010] In the above technical solution, the connecting feet of the speaker upper housing are hollow connecting feet. The upper end of the connecting foot is open, and the connecting hole is provided at the lower end of the connecting foot.

[0011] In the above technical solution, a reflecting surface for reflecting sound waves is provided on the lower side of the speaker upper housing. This reflecting surface can reflect sound waves 360 degrees to the outside of the four sides of the speaker. The reflecting surface is an inverted conical reflecting surface, or an inverted pyramid-shaped reflecting surface, or a rotating curved surface reflecting surface.

[0012] The beneficial effects of this utility model are: (1) Since the speaker is installed at the upper end of the lower shell of the speaker box and the speaker’s sound output direction is upward, the upper shell of the speaker box and the lower shell of the speaker box are spaced apart, and there is a sound outlet for the speaker to output sound between the upper shell of the speaker box and the lower shell of the speaker box, the sound emitted by the speaker can be reflected by the upper shell of the speaker box and emitted from the sound outlet to the surrounding area. The sound coverage of the speaker box is wide and the stereo effect is good, which can meet the surround sound field requirements of the conference scene; (2) Since there is a seal between the annular convex ring and the outer edge of the speaker in this utility model, Therefore, the sealing ring can prevent the speaker from loosening and leaking due to vibration; (3) Since the connecting feet of the upper shell of the speaker are pressed on the outer edge of the speaker to fix the speaker, on the one hand, the speaker does not need to be connected to the lower shell of the speaker; on the other hand, through the one-time assembly process of the connecting feet of the upper shell of the speaker and the lower shell of the speaker, the speaker and the lower shell of the speaker can achieve a stable positioning, so that the assembly efficiency of the speaker mounting structure is high, no secondary processing is required, and it can be directly assembled in one step. In addition, in the preferred embodiment of the present invention, the lower side of the upper shell of the speaker is provided with a reflective surface for reflecting sound waves. The reflective surface can reflect sound waves 360 degrees to the outside of the speaker. This structure can enable the present invention to expand the coverage range and enhance the stereo effect through sound wave reflection, which is suitable for the surround sound field requirements of the conference scene.

[0020] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, this utility model is a speaker mounting structure for a speaker enclosure, including a lower speaker shell 1, a speaker 2, a sealing ring 3, an upper speaker shell 4, and several screws 5. The lower speaker shell 1 has an inner cavity 11, and the upper end of the lower speaker shell 1 has a speaker mounting port 12. The inner wall of the speaker mounting port 12 has an annular protrusion 13. The outer edge of the speaker 2 is mounted on the annular protrusion 13, and the sound output direction of the speaker 2 faces upward. The sealing ring 3 is placed between the annular protrusion 13 and the outer edge of the speaker 2. The upper speaker shell 4 and the lower speaker shell 5 are connected to the lower speaker enclosure. The lower shell 1 is spaced apart, and there is a sound outlet 6 between the upper shell 4 and the lower shell 1 for the speaker 2 to emit sound; the upper shell 4 is connected with a number of connecting feet 41, each connecting foot 41 is provided with a connecting hole 411, and the upper end of the lower shell 1 is provided with a number of screw holes 14 corresponding to the connecting holes 411. The screw 5 passes through the connecting holes 411 and is screwed into the screw holes 14, so that the connecting feet 41 are fixedly connected to the lower shell 1; the connecting feet 41 of the upper shell 4 press on the outer edge of the speaker 2 to press and fix the speaker 2. The sound emitted by the speaker 2 of this invention can be reflected by the upper shell 4 of the speaker box and emitted from the sound outlet 6 in all directions. The sound box has a wide sound coverage and good stereo effect, which can meet the surround sound field requirements of the conference scene. The sealing ring 3 of this invention can prevent the speaker 2 from loosening and leaking due to vibration. Since the connecting feet 41 of the upper shell 4 of this invention press on the outer edge of the speaker 2 to fix the speaker 2, on the one hand, the speaker 2 does not need to be provided with a separate speaker 2 fixing part for connecting to the lower shell 1 of the speaker box. On the other hand, through the one-time assembly process of the connecting feet 41 of the upper shell 4 and the lower shell 1 of the speaker box, the speaker 2 and the lower shell 1 of the speaker box can achieve a stable positioning. Therefore, the assembly efficiency of the speaker 2 mounting structure is high, and no secondary processing is required. It can be directly assembled in one step.

[0022] In a preferred embodiment of this invention, the sealing ring 3 is an EVA sealing ring.

[0023] like Figure 3 As shown, the speaker 2 of this utility model includes a frame 21 and a paper cone 22 mounted on the frame 21. The outer edge of the frame 21 is mounted on an annular convex ring 13. The sealing ring 3 is placed between the annular convex ring 13 and the outer edge of the frame 21. The connecting foot 41 of the speaker housing 4 presses on the outer edge of the paper cone 22.

[0024] like Figures 1-4As shown, the speaker upper shell 4 is connected with three connecting feet 41. The three connecting feet 41 are arranged in a "pin" shape, and the three connecting feet 41 divide the sound outlet 6 into three sound outlet parts. This structure, on the one hand, can fix the speaker upper shell 4 simultaneously from three positions, making the installation of the speaker upper shell 4 stable; on the other hand, it can press the edge part of the speaker 2 simultaneously from three positions, making the installation of the speaker 2 stable.

[0025] As Figure 2 and Figure 4 shown, the connecting feet 41 of the speaker upper shell 4 are hollow connecting feet 41. The upper end of the connecting feet 41 is open, and the lower end of the connecting feet 41 is provided with the connecting holes 411. This structure can make the screw installation convenient.

[0026] As Figure 1 , Figure 4 , Figure 5 and Figure 6 shown, as a preferred mode of the present invention, a reflecting surface 42 for reflecting sound waves is provided on the lower side of the speaker upper shell 4. This reflecting surface 42 can reflect sound waves 360 degrees to the outside of the four sides of the speaker. This structure can enable the present invention to expand the coverage range and enhance the three-dimensional sense through sound wave reflection, meeting the requirements of the surrounding sound field in the conference scene. Preferably, the reflecting surface 42 is an inverted conical reflecting surface, or an inverted pyramidal reflecting surface, or a rotating curved surface reflecting surface; the reflecting surface 42 is most preferably an inverted conical reflecting surface, which can reflect the sound waves S evenly 360 degrees to the outside of the four sides of the speaker.

[0027] The above are only the preferred embodiments of the present invention. Any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical solutions of the present invention shall fall within the scope of the technical solutions of the present invention.
