Description

Technical Field

[0001] This utility model relates to a stereo Bluetooth speaker, specifically a self-rotating stereo Bluetooth speaker. Background Technology

[0002] A Bluetooth speaker is a speaker with a built-in Bluetooth chip and wireless receiving capabilities. It pairs and connects to devices such as mobile phones, tablets, and computers via Bluetooth technology, wirelessly transmitting audio signals to the speaker to play various audio content including music, radio, and voice messages. Bluetooth speakers are portable, compact, and lightweight, making them easy to carry and suitable for use in various scenarios such as home, office, and outdoors, providing people with a convenient audio playback experience.

[0003] A self-rotating Bluetooth speaker is an audio device that incorporates a unique rotating function into a traditional Bluetooth speaker. Its rotation methods are diverse. Some rely on magnetic levitation technology to allow the speaker body to rotate in mid-air, using electromagnetic force to counteract gravity, freeing the speaker from physical constraints and allowing it to play music while rotating at a constant speed. This enables the sound to resonate with the air 360° omnidirectionally, bringing an ethereal and melodious auditory experience. Others use a motor to drive a rotating shaft, causing the speaker body to rotate clockwise or counterclockwise in the horizontal direction, thereby achieving arbitrary adjustment of the playback angle on the horizontal plane. Self-rotating Bluetooth speakers are suitable for various scenarios; in a home environment, they can be a powerful tool for enhancing the ambiance.

[0004] Traditional speakers have fixed speaker positions, resulting in a limited sound field radiation angle and range, making it difficult to create a layered spatial acoustic distribution and leading to insufficient immersion and envelopment in the sound. Secondly, most speakers have fixed function modes, making it difficult to adjust flexibly according to different scenario needs. They are not suitable for both entertainment scenarios that pursue dynamic sound effects and background playback scenarios that require a stable sound field, resulting in poor scenario adaptability. Thirdly, although traditional self-rotating speakers have the advantage of a 360° sound field, the sound emission angle is still limited by the fixed structure, resulting in uneven audio coverage and differences in the listening experience at different positions. Utility Model Content

[0005] The purpose of this invention is to provide a self-rotating stereo Bluetooth speaker to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A self-rotating stereo Bluetooth speaker includes a support base, a cavity formed on the top of the support base, and a speaker housing rotatably mounted on the cavity. A drive motor and a self-rotating component connected to the output shaft of the drive motor for driving the speaker housing to rotate are fixedly mounted on the cavity. A connecting plate is provided between the speaker housing and the self-rotating component. A sliding cavity and a speaker mechanism slidably mounted on the sliding cavity are formed on the speaker housing. A retractable guide mechanism is fixedly connected to one end of the speaker mechanism. A guide mechanism is fixedly mounted on the top of the cavity.

[0008] The guiding mechanism includes a limiting guiding mechanism fixedly installed on the top of the cavity for driving the speaker mechanism to reciprocate up and down, and the limiting guiding mechanism is provided with an adjustable mechanism.

[0009] The self-rotating stereo Bluetooth speaker as described above: the speaker mechanism includes guide rods disposed on both sides of the sliding cavity and a Bluetooth speaker module slidably mounted on the guide rods, the Bluetooth speaker module being slidably mounted on the sliding cavity.

[0011] The self-rotating stereo Bluetooth speaker as described above: the retractable guide mechanism further includes a ball bearing that is rolled on the mounting universal joint, the ball bearing being disposed at one end of the connecting cylinder.

[0012] The self-rotating stereo Bluetooth speaker as described above: the limiting and guiding mechanism includes a guide post fixedly installed on the cavity and a corrugated guide groove formed on the guide post. The guide post is hollow, and the ball bearing is slidably installed on the corrugated guide groove.

[0013] The self-rotating stereo Bluetooth speaker as described above: the adjustable mechanism includes a rotating handle disposed in the guide post and a lead screw fixedly mounted on the rotating handle, the lead screw being rotatably mounted in the guide post.

The arc-shaped cylinder fits against the outer wall of the guide column and is in a ball bearing compression fit.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the self-rotating stereo Bluetooth speaker innovatively adopts a sliding connection structure between the speaker module and the speaker housing. During the overall rotation of the speaker, the speaker module can simultaneously achieve up-and-down reciprocating motion. Through the combined motion of rotation and up-and-down displacement, the speaker module can dynamically change the sound field radiation angle and range, forming a more layered spatial acoustic distribution in conjunction with the stereo architecture, effectively enhancing the sense of immersion and envelopment of the sound effect.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figures 1-10 As an embodiment of this utility model, the self-rotating stereo Bluetooth speaker includes a support base 1, a cavity 2 formed on the top of the support base 1, and a speaker housing 6 rotatably mounted on the cavity 2. A drive motor 3 and a self-rotating component 4 connected to the output shaft of the drive motor 3 for driving the speaker housing 6 to rotate are fixedly mounted on the cavity 2. A connecting plate 5 is provided between the speaker housing 6 and the self-rotating component 4. A sliding cavity 7 and a speaker mechanism slidably mounted on the sliding cavity 7 are formed on the speaker housing 6. A retractable guide mechanism is fixedly connected to one end of the speaker mechanism. A guide mechanism is fixedly mounted on the top of the cavity 2.

[0030] The guiding mechanism includes a limiting guiding mechanism fixedly installed on the top of the cavity 2 for driving the speaker mechanism to reciprocate up and down, and the limiting guiding mechanism is provided with an adjustable mechanism.

[0031] In this embodiment, the self-rotating stereo Bluetooth speaker innovatively adopts a sliding connection structure between the speaker module and the speaker housing. The speaker housing 6 is rotatably mounted on the top of the support base 1. The drive motor 3 and the self-rotating component 4 drive the connecting plate 5 and the speaker housing 6 to rotate. During the rotation of the speaker housing 6, the limiting guide mechanism can limit the vertical movement of the speaker mechanism. During the overall rotation of the speaker, the speaker module can simultaneously achieve vertical reciprocating motion. Through the combined motion of rotation and vertical displacement, the speaker module can dynamically change the sound field radiation angle and range, forming a more layered spatial acoustic distribution in conjunction with the stereo architecture, effectively enhancing the sense of immersion and envelopment of the sound effect.

[0032] Simultaneously, the adjustable mechanism can drive the retractable guide mechanism on one side of the speaker mechanism to retract, causing the speaker mechanism to disengage from the limiting guide mechanism, thereby eliminating the limitation on the speaker mechanism. Considering different usage scenarios and user needs, this design allows users to freely turn off the up-and-down movement mode of the speaker module. When users need a more stable and focused sound field performance, they can choose to turn off this function, so that the speaker module only rotates, thereby simplifying the system movement mode, improving operational stability, and reducing mechanical wear and energy consumption.

[0033] As a further embodiment of this utility model, the speaker mechanism includes guide rods 8 disposed on both sides of the sliding cavity 7 and a Bluetooth speaker module 9 slidably mounted on the guide rods 8, wherein the Bluetooth speaker module 9 is slidably mounted on the sliding cavity 7.

[0034] In this embodiment, the Bluetooth speaker module 9 has a built-in Bluetooth chip and wireless receiving function. The Bluetooth speaker module 9 is slidably mounted on the sliding cavity 7 via guide rods 8 on both sides.

[0035] As a further embodiment of this utility model, the retractable guide mechanism includes a connecting cylinder 10 fixedly installed on one side of the Bluetooth speaker module 9 and a spring 11 fixedly installed on the connecting cylinder 10, with one end of the spring 11 connected to a universal joint.

[0036] In this embodiment, the connecting cylinder 10 is fixed to the rear end of the Bluetooth speaker module 9, the spring 11 is elastically disposed inside the connecting cylinder 10, and the mounting universal joint is fixed to one end of the spring 11.

[0037] As a further embodiment of this utility model, the retractable guide mechanism further includes a ball bearing 12 that is rolled on the mounting universal joint, and the ball bearing 12 is disposed at one end of the connecting cylinder 10.

[0038] In this embodiment, the ball bearing 12 is rolled on the mounting universal joint, and the ball bearing 12 can retract into the interior of the connecting cylinder 10.

[0039] As a further embodiment of this utility model, the limiting and guiding mechanism includes a guide post 13 fixedly installed on the cavity 2 and a corrugated guide groove 14 formed on the guide post 13. The guide post 13 is hollow, and the ball bearing 12 is slidably installed on the corrugated guide groove 14.

[0040] In this embodiment, a corrugated guide groove 14 is formed on the outer wall of the connecting cylinder 10, and the corrugated guide groove 14 guides the movement of the ball 12.

[0041] As a further embodiment of this utility model, the adjustable mechanism includes a rotating handle 15 disposed in the guide post 13 and a lead screw 16 fixedly mounted on the rotating handle 15, wherein the lead screw 16 is rotatably mounted in the guide post 13.

[0042] In this embodiment, the rotating handle 15 is fixedly sleeved on the bottom end of the lead screw 16, and the top of the lead screw 16 is rotatably connected to the guide post 13.

[0043] As a further embodiment of this utility model, the lead screw 16 is threaded with an internal thread moving part 17 and an arc-shaped cylinder 18 fixedly mounted on the internal thread moving part 17. The arc-shaped cylinder 18 fits against the outer wall of the guide post 13 and is in a compression fit with the ball bearing 12.

[0044] In this embodiment, as the Bluetooth speaker module 9 rotates with the speaker housing 6, the ball bearing 12 at one end of the Bluetooth speaker module 9 is slidably mounted on the corrugated guide groove 14. When the Bluetooth speaker module 9 rotates, the ball bearing 12 slides towards the corrugated guide groove 14, simultaneously achieving up-and-down reciprocating motion. Through this combined rotational and vertical displacement motion, considering different usage scenarios and user needs, the rotating handle 15 at the bottom of the rotating support base 1 can drive the lead screw 16 to rotate. The lead screw 16 then drives the internally threaded moving part 17 to slide up and down. The threaded moving part 17 drives the arc-shaped cylinder 18 to move upward. At the same time, the arc-shaped cylinder 18 first squeezes the ball 12 into the connecting cylinder 10 and compresses the spring 11. Then, the arc-shaped cylinder 18 covers the corrugated guide groove 14, so that the ball 12 moves out of the corrugated guide groove 14. The up and down movement mode of the speaker module can be freely turned off. When the user needs a more stable and focused sound field performance, this function can be turned off, so that the speaker module only rotates, thereby simplifying the system movement mode, improving the operational stability, and reducing mechanical wear and energy consumption.

[0045] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
