Description

Technical Field

[0001] This invention relates to the field of audio technology, and in particular to a modular top-mounted embedded speaker. Background Technology

[0002] Speakers are a common amplification tool in daily life, and they can be categorized into ceiling-mounted, wall-mounted, and floor-standing types based on their installation method. Ceiling-mounted speakers typically do not require additional floor space, wall hooks, or special brackets, thus preserving the aesthetics of the decor. They also offer greater freedom in placement and a wider sound projection range.

[0003] However, existing ceiling-mounted speakers typically use bolts to connect the speaker's mounting structure to the ceiling. This method is not only labor-intensive but also prone to damaging the ceiling structure. Furthermore, because the mounting structure is usually an integral part of the speaker itself, it's impossible to replace the speaker or its mounting structure separately, resulting in poor adaptability. Disassembly and reassembly require the entire speaker and its mounting structure to be disassembled, and partial damage necessitates replacement of the entire unit, leading to high repair costs. Additionally, existing ceiling-mounted speakers, limited by the installation environment, suffer from insufficient low-frequency sound output and poor bass performance.

[0004] Therefore, how to design a modular top-mounted embedded speaker that allows for easy disassembly and assembly, enables individual replacement of the speaker module to reduce maintenance costs, and provides better bass performance is a technical problem that designers and developers need to solve. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a modular top-mounted embedded speaker that, while enabling convenient assembly and disassembly, allows for the individual replacement of the speaker module, reducing maintenance costs, and also delivers better bass performance.

[0006] The objective of this invention is achieved through the following technical solution:

[0014] In one embodiment, there are multiple snap-fit ​​structures, which are integrally formed with the base body and are elastic. The holding part is an annular protruding ridge structure that cooperates with the snap-fit ​​structure.

[0015] In one embodiment, the housing has a stepped groove at the edge of the auxiliary window, and the resonant diaphragm has a central portion and an edge portion, with the edge portion conforming to the inner wall of the stepped groove.

[0016] In one embodiment, the auxiliary window is located on the top wall, and the center of the auxiliary window coincides with the central axis of the receiving cavity.

[0017] In one embodiment, there are multiple auxiliary windows, which are located on the sidewall and are evenly spaced.

[0018] In one embodiment, the amplification component includes a first mesh cover disposed on the resonant diaphragm, the first mesh cover having a plurality of first vent holes; the sound-generating component includes a cone diaphragm and a second mesh cover disposed on the cone diaphragm, the second mesh cover having a plurality of second vent holes.

[0019] In one embodiment, the base body has an outer edge, and the base body is provided with a plurality of limiting members for cooperating with the outer edge. The plurality of limiting members are evenly distributed on the base body, and each limiting member is provided with a torsion spring. The limiting member is rotatably mounted on the base body by the torsion spring.

[0020] In one embodiment, the audio module includes an annular elastic sheet disposed at the edge of the sound outlet, and the base body has a mounting groove at the end of the through hole, with the elastic sheet being clamped between the housing and the groove wall of the mounting groove.

[0036] This invention provides a modular top-mounted embedded speaker 10, which, while enabling convenient disassembly and assembly, allows for the individual replacement of the speaker module 100, reducing maintenance costs. Figures 1 to 3As shown, the modular top-mounted embedded speaker 10 includes a speaker module 100 and a base module 200, with the speaker module 100 being detachably mounted on the base module 200.

[0037] The audio module 100 includes a housing 110, a sound-generating component 120, and an amplifying component 130. The housing 110 has a receiving cavity 111, which has a sound outlet 1111 and an auxiliary window 1112. The sound outlet 1111 faces the through hole 220, and the auxiliary window 1112 is away from the sound outlet 1111. The sound-generating component 120 is housed in the receiving cavity 111 and is located at the sound outlet 1111.

[0038] The base module 200 includes a base body 210, which has a through hole 220 and a snap-fit ​​structure 230. The audio module 100 is mounted on the end of the through hole 220 via the snap-fit ​​structure 230. The sound waves generated by the audio module 100 can be transmitted to the outside through the through hole 220.

[0039] During the packaging and transportation process, the audio module 100 and the base module 200 can be packaged and transported separately. Compared with packaging and transporting the audio module 100 and the base module 200 together, this method allows for more flexible packaging and transportation, occupies less space, and reduces transportation costs.

[0040] In practical use, users can fix the modular top-mounted recessed speaker 10 to the ceiling, bracket, or other desired installation locations. The following description uses the ceiling as an example. During installation, the base module 200 is first installed on the ceiling, and then the speaker module 100 is combined with the base module 200. When replacing, only the speaker module 100 or the base module 200 needs to be replaced, without the need for complete disassembly and replacement, thus reducing maintenance costs.

[0041] In some embodiments, a lamp can be used to replace the speaker module 100, that is, the speaker module 100 is removed from the base module 200 and the lamp is installed on the base module 200 to achieve the lighting function. Users can choose to install either the speaker module 100 or a lamp according to the actual situation, which expands the application range of the modular top-mounted embedded speaker 10.

[0042] To facilitate the assembly and disassembly of the audio module 100 and the base module 200, this invention features a specially designed connection structure between the two. For example... Figures 3 to 8 As shown, the housing 110 has a retaining part 112 at the sound outlet 1111, and the retaining part 112 is movably connected to the latching structure 230. Understandably, the latching structure 230 needs to be at least partially elastic to clamp the retaining part 112 and prevent the audio module 100 from detaching from the base module 200. This design can be implemented in various ways. Specifically,

[0043] In one embodiment, such as Figure 7 As shown, the snap-fit ​​structure 230 has a main body 231 and at least one elastic part 232. The main body 231 is annular and is fixedly connected to the base body 210. The elastic part 232 is mounted on the main body 231. After the audio module 100 and the base module 200 are assembled, the elastic part 232 can abut against the retaining part 112 and apply a downward force to the retaining part 112, thereby limiting the audio module 100. Preferably, the retaining part 112 is an annular protruding ridge structure that cooperates with the elastic part 232. This avoids the problem of needing to adjust the angle multiple times to align the retaining part 112 and the elastic part 232 during installation, and will not disengage due to the vibration and rotation of the audio module 100, ensuring the stability of the connection.

[0044] In another embodiment, such as Figure 8 As shown, there are multiple snap-fit ​​structures 230, which are integrally formed with the base body 210 and are elastic. After the audio module 100 and the base module 200 are assembled, the snap-fit ​​structures 230 can abut against the holding part 112 and apply a downward force to the holding part 112, thereby limiting the audio module 100. Multiple snap-fit ​​structures 230 can simultaneously abut against the holding part 112, effectively ensuring the stability of the connection between the audio module 100 and the base module 200.

[0045] Furthermore, during the combined use of the audio module 100 and the base module 200, the following problems still exist, such as unreliable connections and abnormal noises caused by vibration. Therefore, as... Figures 3 to 5 As shown, the audio module 100 has an annular elastic sheet 140, which is located at the edge of the sound outlet 1111. The base body 210 has a mounting groove 214 at the end of the through hole 220, and the elastic sheet 140 is clamped between the housing 110 and the groove wall of the mounting groove 214. This design has the following advantages:

[0046] Firstly, due to unavoidable processing errors, there may be a problem of loose connection caused by excessive gap between the snap-fit ​​structure 230 and the holding part 112. After setting the elastic sheet 140, the elastic sheet 140 can produce elastic deformation when squeezed, thereby compensating for the processing error, eliminating the gap between the snap-fit ​​structure 230 and the holding part 112, and ensuring the reliability of the connection.

[0047] Secondly, during operation, the speaker module 100 emits sound and vibrates, which can cause it to collide with the base module 200, resulting in abnormal noise and affecting sound quality, thus reducing the user experience. By setting the elastic sheet 140, the collision between the speaker module 100 and the base module 200 can be effectively reduced, thereby avoiding abnormal noise and improving sound quality and user experience.

[0048] Third, the elastic sheet 140 is deformed under compression, thereby tightly fitting the shell 110 and the groove wall of the mounting groove 214, effectively ensuring the sealing of the connection between the shell 110 and the base body 210, and avoiding the problem of some sound waves escaping from the connection and affecting the sound quality.

[0049] Furthermore, the modular top-mounted embedded speaker 10 of the present invention also has better bass performance. For example... Figure 4 and Figure 5 As shown, the amplification component 130 is disposed on the housing 110 and located at the auxiliary window 1112. The amplification component 130 includes a resonant diaphragm 131, which blocks the auxiliary window 1112, and the sound-generating component 120 blocks the sound outlet 1111, so that the receiving cavity 111 forms a closed cavity.

[0050] It should be noted that the sound-generating assembly 120 includes a cone diaphragm 121. The sound-generating assembly 120 generates sound waves by vibrating the cone diaphragm 121 to push air. Since the resonant diaphragm 131 and the cone diaphragm 121 are located in the same enclosed cavity 111, when the cone diaphragm 121 vibrates, the air pressure inside the cavity 111 changes. This air pressure change drives the resonant diaphragm 131 to vibrate accordingly. That is, the resonant diaphragm 131 also vibrates to generate sound, thereby enhancing the bass effect and making the sound emitted by the audio module 100 more three-dimensional.

[0051] In existing ceiling-mounted speakers, the inner wall of the sound cavity is usually formed by multiple straight walls connected directly. Therefore, there are often sharp angles and transitions, such as right angles and acute angles, which cause right-angle reflections or standing waves when sound waves propagate within the sound cavity. Standing waves can cause uneven stress on the resonant diaphragm 131, resulting in unstable vibration and affecting bass sound quality.

[0052] To address this problem, the present invention reduces the number of bends within the receiving cavity 111. Specifically, as shown below... Figure 6 As shown, the housing 110 has a top wall 114 and a side wall 115. The top wall 114 is opposite to the sound outlet 1111. A circular arc transition surface 116 connects the top wall 114 and the side wall 115, achieving a curved surface connection. This design has the following advantages:

[0053] Firstly, the reduction of the bend structure within the cavity 111 allows the arc transition surface 116 to guide sound waves to diffuse evenly along the tangent direction of the arc transition surface 116, reducing the formation of standing waves and avoiding uneven stress on the resonant diaphragm 131 caused by standing waves, which can lead to mixed sound quality. For example, when there is only one resonant diaphragm 131, some areas of the single resonant diaphragm 131 may vibrate more strongly than others, resulting in unstable vibration and thus mixed sound quality. When there are multiple resonant diaphragms 131, due to their different stress conditions, the vibration amplitudes of the multiple resonant diaphragms 131 may differ, leading to mixed sound quality.

[0054] Secondly, by reducing the formation of standing waves, the abnormal amplification or attenuation of specific frequencies caused by standing waves is avoided, thus preventing problems such as muddy sound quality and blurred layers, and ensuring that the resonant sound generated in the cavity 111 is clear.

[0055] Thirdly, it avoids the situation where the air flowing rapidly in the cavity 111 with the vibration of the diaphragm 121 suddenly turns and forms turbulence when passing through the turning structure during the sound production process, thereby reducing the generation of noise and ensuring the purity of the sound.

[0056] Furthermore, such as Figures 4 to 6 As shown, the housing 110 has a stepped groove 113 at the edge of the auxiliary window 1112. The resonant diaphragm 131 has a central portion 1311 and an edge portion 1312, with the edge portion 1312 fitting against the inner wall of the stepped groove 113. At this time, the resonant diaphragm 131 forms a state of "fixed periphery, suspended center," meaning the edge portion 1312 is connected to the stepped groove 113, while the central portion 1311 is suspended. This minimizes contact between the central portion 1311 and other structures, preventing vibrational energy from being absorbed or lost by other structures. When the cone diaphragm 121 vibrates, the central portion 1311 can freely follow its vibration, allowing for a larger amplitude and higher transmission efficiency, thus more effectively enhancing the bass effect.

[0057] Preferably, such as Figure 4 As shown, the auxiliary window 1112 can be located on the top wall 114, and the center of the auxiliary window 1112 coincides with the central axis of the receiving cavity 111. Understandably, the resonant diaphragm 131 is relatively far away from the cone diaphragm 121, so that the resonant diaphragm 131 is subjected to overall force balance, thereby efficiently amplifying low-frequency energy and enhancing the bass effect.

[0058] In other embodiments, such as Figure 5As shown, multiple auxiliary windows 1112 can be located on the sidewall 115, and the multiple auxiliary windows 1112 are evenly spaced. Understandably, at this time, there are more resonant diaphragms 131, which can drive more air to form stronger sound waves. These sound waves have a more obvious impact on the human ear and a better listening experience.

[0059] like Figure 4 As shown, the amplification component 130 includes a first mesh cover 132, which is disposed on the resonant diaphragm 131. The first mesh cover 132 has multiple first vent holes 1321. The first mesh cover 132 protects the resonant diaphragm 131, and the multiple first vent holes 1321 ensure effective sound wave transmission. Simultaneously, it prevents air pressure changes in the space between the first mesh cover 132 and the resonant diaphragm 131, thus avoiding any impact on the vibration of the resonant diaphragm 131 and ensuring optimal sound output.

[0060] like Figure 4 and Figure 5 As shown, the sound-generating assembly 120 includes a second mesh cover 122, which is disposed on the diaphragm 121. The second mesh cover 122 has multiple second vent holes 1221. The function of the second mesh cover 122 is similar to that of the first mesh cover 132, which can protect the diaphragm 121 and prevent it from affecting the vibration of the diaphragm 121.

[0061] To enable quick assembly and disassembly of the base body 210 relative to the ceiling, such as Figure 7 and Figure 8 As shown, the base body 210 is provided with an outer edge 211, and the base body 210 is provided with a plurality of limiting members 212 for cooperating with the outer edge 211. The plurality of limiting members 212 are evenly distributed on the base body 210, and a torsion spring 213 is provided on the limiting member 212. The limiting member 212 is rotatably mounted on the base body 210 by the torsion spring 213.

[0062] In use, the user drills a mounting hole in the ceiling, the diameter of which is slightly smaller than the outer diameter of the outer edge 211. During installation, the user only needs to apply force to twist the limiting member 212, causing it to rotate under force; then, the base module 200 is inserted into the mounting hole until the limiting member 212 is inside the mounting hole, at which point the user can release the grip. At this point, the limiting member 212 automatically resets under the elastic force of the torsion spring 213, thus engaging with the outer edge 211 to secure it to the ceiling. When disassembly is required, simply apply force to twist the limiting member 212 and simultaneously remove the modular top-mounted recessed speaker 10 from the mounting hole. This allows for quick and easy installation and removal of the modular top-mounted recessed speaker 10 from the ceiling.

[0063] like Figure 2As shown, the through hole 220 has a first end 221 and a second end 222. The diameter of the first end 221 is smaller than the diameter of the second end 222. The through hole 220 is frustum-shaped, and the audio module 100 is disposed on the first end 221. In this way, the through hole 220 forms a speaker-like structure, thereby amplifying the sound emitted by the sound-generating component 120 and improving the propagation efficiency of the sound waves.

[0064] In summary, the modular top-mounted embedded speaker 10 provided by the present invention not only enables convenient disassembly and assembly, but also allows for the individual replacement of the speaker module 100, reducing maintenance costs, and provides better bass performance.

[0065] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
