Description

Technical Field

[0001] This application belongs to the field of audio equipment technology, and specifically relates to a liftable loudspeaker. Background Technology

[0002] In loudspeaker applications, the rationality of the installation structure directly affects equipment compatibility and sound field optimization. Traditional loudspeaker installations often employ exposed fixing methods, primarily achieved through expansion screw fastening, metal bracket welding, and direct bolt tightening. This involves directly fixing the loudspeaker body or its mounting frame to the surface of a carrier such as a wall, ceiling, or independent bracket, resulting in a completely exposed installation. This type of fixing method, due to the absence of complex transmission structures, offers advantages such as low processing costs and simple assembly processes, and was widely used in early indoor installation scenarios. However, once the height of a speaker is fixed, it cannot be adjusted according to actual usage needs, resulting in insufficient sound field adaptability. Specifically, the sound propagation range of a speaker is directly related to its height. For example, in a large conference room, if the seating arrangement of the audience changes, or if it is necessary to optimize sound coverage for people of different heights, a speaker of fixed height cannot adapt to the sound field requirements by adjusting its position, resulting in some areas having weak sound or echoes, affecting the listening experience and increasing the difficulty of scene switching.

[0003] If the height of a traditional exposed loudspeaker needs to be adjusted, it requires disassembling expansion screws and cutting welding points, which not only consumes a lot of time, but also causes irreversible damage such as holes and scratches to the mounting surfaces such as walls and brackets. Subsequent reinstallation requires repositioning and drilling, further increasing the operating cost. The equipment compatibility is limited and the flexibility of auditory adjustment is poor. Utility Model Content To address the shortcomings of the prior art, this application provides a liftable speaker. Through the design of the lift component, the height of the speaker can be flexibly adjusted according to the needs of the scenario, effectively improving the sound field adaptability and greatly enhancing the listening experience.

A horn assembly includes an inner shell and a horn component, wherein the horn component is embedded and connected to the inner shell, the outer shell is sleeved on the inner shell, and the lower end of the inner shell is fixedly connected to the driving component. The lifting assembly is used to move the horn assembly up and down within the outer casing, so that the horn assembly is at different heights.

[0005] In some implementations, the driving component includes a motor and a gear, with the driving end of the motor being driven by the gear and the mounting end of the motor being fixedly connected to the lower end of the inner shell.

[0006] In some implementations, the transmission component is a rack and pinion transmission component, which meshes with the gear.

[0007] In some implementations, a guide rail is provided on the outer side of the inner shell corresponding to the limiting rail, and the guide rail is wrapped around the limiting rail.

[0008] In some implementations, the horn assembly further includes a control component connected to the upper end of the inner shell and electrically connected to the lifting assembly and the horn assembly.

[0009] In some implementations, the control component includes: The storage shell is connected to the upper end of the inner shell, and the storage shell has a storage cavity inside; A control board, located in the storage cavity and electrically connected to the lifting assembly and the horn component, is used to control the state of the lifting assembly and the horn component; and The control board cover is attached to the upper end of the housing and is electrically connected to the control motherboard for operating the control motherboard.

[0010] In some implementations, the control component further includes a wireless charging module, which is integrated on the control motherboard; the wireless charging module is used to wirelessly power external electrical devices.

[0011] In some implementations, a limiting plate is provided at the lower end of the inner shell, and a transistor signal sensor is provided inside the limiting plate. The transistor signal sensor is electrically connected to the control motherboard. A strong magnetic block is embedded in the upper part of the outer shell.

[0012] In some implementations, a push-button switch is provided at one end of the storage shell corresponding to the outer shell portion, and the push-button switch is electrically connected to the control motherboard; The upper end of the outer casing is provided with a protrusion, which is positioned opposite to the push-button switch.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0026] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0027] Example 1: Please see the appendix Figure 1-2 The liftable loudspeaker of this application includes a lift assembly 1, a fixing assembly 2, and a speaker assembly 3. The lift assembly 1 includes a drive component 11 and a transmission component 12, with the drive component 11 and the transmission component 12 being drivenly connected. The fixing assembly 2 includes a housing portion 21, with a limiting rail 211 provided inside the housing portion 21, and the transmission component 12 being embedded and connected within the limiting rail 211. The speaker assembly 3 includes an inner housing portion 31 and a speaker component 32, with the speaker component 32 being embedded and connected to the inner housing portion 31. The outer housing portion 21 is fitted onto the inner housing portion 31, and the lower end of the inner housing portion 31 is fixedly connected to the drive component 11. The lift assembly 1 is used to drive the speaker assembly 3 to move up and down within the housing portion 21, so that the speaker assembly 3 is in different height states.

[0028] Preferably, the crossover unit in the speaker component 32 adopts a combination of a 3-inch full-range speaker and a 3-inch woofer, paired with a racetrack-shaped 4Ω 20W 4580 speaker. The frequency response starts at F0 18KHZ, the distortion is strictly controlled to <5%, the sound pressure level can reach 85dB±3dB, the resonance frequency is stable at 150HZ±10%, the maximum power of a single speaker is 25W, and two sets of left and right channels are integrated internally to ensure stereo output effect. By cleverly combining the speaker component 32, the inner shell 31 and the drive component 11, a sealed state is achieved, which effectively reduces sound wave leakage, thereby significantly improving the fullness and depth of low frequencies, and enhancing the overall acoustic performance of the speaker.

[0029] In this embodiment, when the height of the speaker assembly 3 needs to be adjusted, the drive component 11 is activated. Since the transmission component 12 is connected to the limiting rail 211 and the lower end of the inner shell 31 is fixedly connected to the drive component 11, the drive end of the drive component 11 moves along the transmission component 12, thereby driving the inner shell 31 to perform a lifting action within the outer shell 21. This allows the speaker assembly 3 to rise or fall a certain height from the outer shell 21, and the height of the speaker assembly 3 can be flexibly adjusted according to the needs of scene switching, effectively improving the sound field adaptability.

[0030] Through the above technical solution, the speaker assembly 3 is designed to be raised and lowered within the outer casing 21 using the lifting component 1. When not in use, the speaker assembly 3 can be completely embedded within the outer casing 21, improving its protection. When needed, the speaker assembly 3 can be pushed out of the outer casing 21 to a certain height according to the specific scenario, improving sound field adaptability and providing a better listening experience for the audience. The overall structure uses the drive component 11 to flexibly adjust the height of the speaker assembly 3 without requiring extensive disassembly and reassembly. The overall operation is simple, the structure is easy to maintain, and it is highly practical and applicable to various scenarios.

[0031] In addition, in this structure, by using the limiting rail 211 to embed and fix the transmission component 12, the stability of the connection and placement of the transmission component 12 can be ensured, so that the transmission component 12 is stably placed in the vertical direction, avoiding the phenomenon of jamming of the horn assembly 3 due to the deviation of the movement direction, and ensuring the smoothness and stability of the horn assembly 3 in raising and lowering.

[0032] In some embodiments, please refer to the appendix Figure 2 The driving component 11 includes a motor 111 and a gear 112. The driving end of the motor 111 is connected to the gear 112, and the mounting end of the motor 111 is fixedly connected to the lower end of the inner shell 31. The transmission component 12 is a rack and pinion transmission component 12, which meshes with the gear 112. The horn assembly 3 rises or falls by the forward or reverse rotation of the motor 111.

[0033] Specifically, when the height of the horn assembly 3 needs to be adjusted, the motor 111 is started, which drives the gear 112 to rotate. Since the gear 112 and the rack and pinion drive 12 are meshed and connected, and the drive 12 is fixedly connected to the outer casing 21, the gear 112 moves up or down along the rack and pinion drive 12, thereby driving the horn assembly 3 to lift or lower. This structure is cleverly and simply designed, and is easy to maintain later.

[0034] With this multi-gear 112 reduction transmission structure, the motor 111 drives the gear 112, which in turn engages with the rack synchronously, achieving smooth lifting and lowering, improving lifting stability, and reducing the failure rate. Compared to traditional height-adjustable speakers, this structure effectively extends the speaker's lifespan.

[0035] In some embodiments, see Figure 3 The outer side of the inner shell 31 is provided with a guide rail 311 corresponding to the limiting rail 211, and the guide rail 311 is wrapped around the limiting rail 211. With this setting, when the inner shell 31 of the horn assembly 3 is raised and lowered by the lifting assembly 1, since the guide rail 311 is wrapped around the limiting rail 211, the inner side of the guide rail 311 moves along the outer side of the limiting rail 211, which further restricts the raising and lowering direction of the horn assembly 3, avoids the phenomenon of jamming caused by the raising and lowering deviation, and improves the smoothness and stability of the raising and lowering of the horn assembly 3.

[0036] Example 2: The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 4 The speaker assembly 3 in this embodiment also includes a control component 33, which is connected to the upper end of the inner shell 31 and electrically connected to the speaker assembly 32 of the lifting assembly 1. The control component 33 is used to control the activation of the speaker assembly 32 of the lifting assembly 1, and can control the lifting assembly 1 to raise and lower the speaker assembly 32. By placing the control component 33 at the upper end of the inner shell 31, it is convenient for the user to operate, achieving simple and convenient operation.

[0037] In some embodiments, see Figure 5 The control component 33 includes a storage shell 331, a control main board 332, and a control board cover 333. The storage shell 331 is connected to the upper end of the inner shell 31, and a storage cavity 3311 is provided inside the storage shell 3311. The control main board 332 is located in the storage cavity 3311 and is electrically connected to the horn component 32 of the lifting assembly 1, and is used to control the state of the horn component 32 of the lifting assembly 1. The control board cover 333 is placed on the upper end of the storage shell 331 and is electrically connected to the control main board 332, and is used to operate the control main board 332. The control board cover 333 can be a touch-sensitive cover.

[0038] Specifically, the operator can control the lifting assembly 1 and the horn assembly 3 via the control panel cover 333. This can be achieved by double-tapping the horn assembly 3 with a touch sensor to raise or lower it. The main control board 332 can be designed to stop operation immediately with a single touch, and includes a one-button stop protection function. Different lifting heights can also be set, allowing for user customization.

[0039] Additionally, a protective function can be designed. If the horn assembly 3 encounters unexpected external interference during lifting, it will automatically stop and initiate a protective rebound. The principle behind this protective function is as follows: During the ascent and descent of the horn assembly 3, the chip in the control motherboard 332 determines the normal ascending and descending AD value. When the output voltage and current of the motor 111 suddenly change or exceed the range, the voltage fluctuates, the AD value changes, and the control system detects interference. It then stops operation and reverses the flow for one second, thus achieving the anti-pinch purpose. Understandably, the above design can be implemented using existing designs of the control motherboard 332 according to customer requirements.

[0040] The above settings enable intelligent control of the raising and lowering of the speaker assembly 3, improving ease of use and operation. At the same time, the functional design enhances safety during use.

[0041] In some embodiments, the control component 33 further includes a wireless charging module, which is integrated on the control motherboard 332; the wireless charging module is used to wirelessly power external electrical devices.

[0042] Specifically, the control board cover 333 forms a planar charging area, automatically detecting objects near the coil, such as mobile phones. Placing a phone with wireless charging capability on the control board cover 333 will initiate charging. This design effectively adds extra functionality to the speaker, facilitating phone charging and improving usability. Furthermore, the lifting and automatic charging functions are independent, ensuring that the charging and lifting processes do not interfere with each other and are controlled independently, effectively enhancing the speaker's practicality.

[0043] In some embodiments, see Figure 6 The lower end of the inner shell 31 is provided with a limiting plate 312, and a transistor signal sensor is provided inside the limiting plate 312. The transistor signal sensor is electrically connected to the control main board 332. A strong magnetic block 214 is embedded in the upper end of the outer shell 21.

[0044] Specifically, when the limiting plate 312 at the lower end of the inner shell 31 is rising, when the transistor signal sensor inside the limiting plate 312 approaches and senses the strong magnetic block 214 at the upper end of the outer shell 21, it will give a disconnect signal to stop the rising of the speaker assembly 3, which is at its maximum height. This setting enables intelligent disconnection, avoids damage to the speaker due to excessive rising, ensures timely disconnection, and guarantees the durability of the speaker.

[0045] In some embodiments, see Figure 7-8 The storage housing 331 has a push-button switch 3312 at one end corresponding to the outer casing 21. The push-button switch 3312 is electrically connected to the control main board 332. The upper end of the outer casing 21 has a protrusion 212, which is positioned opposite to the push-button switch 3312. The push-button switch 3312 can be a soft push-button switch 3312, which is more sensitive to operation.

[0046] Specifically, when the speaker assembly 3 descends to the bottom, the protrusion 212 at the upper end of the outer casing 21 abuts against the push-button switch 3312 of the storage shell 331, giving a disconnect signal and stopping the descent. At this point, the speaker assembly 3 is fully embedded in the outer casing 21, which is the lowest position of the speaker assembly 3. With this setting, the speaker assembly 3 can be disconnected in time when it moves to the bottom, avoiding excessive descent, effectively protecting the speaker assembly 3, ensuring the speaker's performance, and improving its durability.

[0047] Example 3: The difference between this embodiment and Embodiment 2 is that, please refer to... Figure 9 The fixing component 2 in this embodiment also includes a locking member 22, the inner wall of which is provided with an internal thread; the upper end of the outer shell 21 is provided with an external thread 213 that is adapted to the internal thread; the locking member 22 is used to lock the fixing component 2 to the mounting surface. The locking member 22 has connecting holes arranged in a ring along its edge for screws to pass through, thereby achieving locking and fixing with the mounting surface.

[0048] In this embodiment, the speaker installation process is as follows: First, the speaker assembly 3 is fully embedded into the housing 21. Then, a hole is made on the mounting surface. Next, the speaker is inserted into the mounting hole so that the uppermost end of the speaker assembly 3 can be placed on the mounting surface. Then, the locking member 22 is put on from the bottom end of the housing 21. The locking member 22 is screwed in counterclockwise along the external thread 213 of the housing 21 through the internal thread and is close to the bottom of the mounting surface. Finally, the screw passes through the locking member 22 and is fixedly connected to the mounting surface, thereby completing the speaker installation.

[0049] Through the aforementioned technical design, the overall installation process is simple and quick, reducing installation difficulty and allowing operators to quickly master the process, thus improving installation efficiency. Furthermore, the adjustable engagement between the locking element 22 and the external thread 213 of the housing 21 allows for adaptation to slight differences in mounting surface thickness, enhancing installation compatibility. Finally, the screw fixing further strengthens the connection, ensuring the speaker remains stable during long-term use and indirectly reducing resonance and noise problems caused by unstable installation, thus contributing to the stability of acoustic performance.
