Figures 1-6 Preferred embodiments of the present invention are given herein. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0024] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] In one embodiment of this utility model, such as Figures 1-6 As shown, a Bluetooth speaker is provided, including a stand module 10, a speaker housing 20, a speaker module 30, and an electronic control module 40. The stand module 10 has an inductor 11 built-in and a placement surface 12 for placing items. The placement surface 12 covers the inductor 11. The inductor 11 receives music played from the speaker of an electronic device (such as a mobile phone) and amplifies the volume, allowing the electronic device (such as a mobile phone) to amplify the volume without needing to connect to Bluetooth. The speaker housing 20 is connected to one end of the stand module 10 via a rotatable connection, and the speaker housing 20 has a mounting cavity 21 inside. The speaker module 30 is installed in the mounting cavity 21 of the speaker housing 20 and is positioned close to the stand module 10. The electronic control module 40 is located inside the mounting cavity 21 and at the end of the speaker housing 20 away from the speaker module 30. Both the inductor 11 and the speaker module 30 are electrically connected to the electronic control module 40, and the electronic control module 40 has a Bluetooth module that can connect with electronic devices via Bluetooth (setting up a Bluetooth module inside the speaker to achieve Bluetooth interconnection with electronic devices such as mobile phones is a very mature existing technology, which will not be elaborated here).

[0027] Specifically, after the electronic control module 40 is connected to a power source, it receives and processes external audio signals, while simultaneously providing adaptive current to the speaker module 30 and the inductor 11. The speaker module 30 vibrates and produces sound under the signal drive of the electronic control module 40, thus realizing the audio playback function. The inductor 11 and the electronic control module 40 form a circuit loop, which can help optimize the filtering and anti-interference performance of the audio signal and improve the sound quality. The mounting surface 12 of the bracket module 10 serves as a support structure, allowing the placement of small items such as mobile phones and tablets. The mounting surface 12 covers the inductor 11, protecting it from external damage without affecting its circuit function.

[0028] The stand module 10 can hold and fix electronic devices, such as mobile phones and tablets. On one hand, combined with inductor coupling technology, by setting an inductor 11 on the stand module 10, when the user places the mobile phone on the stand module 10, the inductor 11 can couple with the inductor coil inside the mobile phone, realizing the transmission of audio signals. When the mobile phone is placed on the stand module 10, the speaker plays music; when the mobile phone is removed from the stand module 10, the mobile phone plays music. On the other hand, the speaker has a Bluetooth connection mode, which can connect to the mobile phone via the Bluetooth module of the electronic control module 40 to play music. Thus, this Bluetooth speaker integrates storage and audio functions, providing users with convenient storage space while saving space in various usage scenarios, and offering a new way to use the device, thus enhancing its practicality.

[0029] The support module 10 includes a hinge 13, a storage component 14, and a limiting component 15. One end of the hinge 13 is pivotally connected to the speaker housing 20, and the other end is pivotally connected to the storage component 14. An inductor 11 is disposed within the storage component 14, and the side of the storage component 14 facing away from the hinge 13 forms a storage plane 12. The limiting component 15 is disposed on the storage component 14 and works together with the storage plane 12 to limit the placement of the item. Specifically, one end of the hinge 13 is pivotally connected to the speaker housing 20, and the other end is pivotally connected to the storage component 14, allowing the storage component 14 to rotate relative to the speaker housing 20 around the hinge 13 to adjust its angle. The limiting component 15 is directly fixed to the storage component 14, forming an integral structure with the storage plane 12 of the storage component 14, together constituting the item limiting space. The inductor 11 inside the storage component 14 is connected to the terminal of the electronic control module 40 inside the speaker housing 20 via a hidden wire. The wire can be arranged along the reserved channel of the hinge 13 to avoid being pulled when flipped.

[0030] Furthermore, the shelf surface 12 is provided with multiple anti-slip protrusions 16, which are evenly spaced and rectangular in shape. The anti-slip protrusions 16 increase the friction of the shelf surface 12, making it less likely for electronic devices to slip when placed on it. The anti-slip protrusions 16 can also be circular, prismatic, or irregular in shape. The shelf surface 12 can be made of rubber material, further enhancing the friction.

[0031] The storage component 14 is provided with a groove 141 for accommodating the limiting component 15. The limiting component 15 is disposed in the groove 141 and is rotatably connected to the storage component 14. Specifically, the groove 141 and the limiting component 15 are adapted to each other. The limiting component 15 and the storage component 14 can be connected by a torsion spring / rotating shaft, etc., so that the limiting component 15 and the storage component 14 can be flipped. The flipping angle between the limiting component 15 and the storage component 14 is between 0° and 90°.

[0032] Furthermore, one end of the limiting member 15 is provided with a limiting part 151 perpendicular to the limiting member 15, and the limiting part 151 is located at the end of the limiting member 15 away from the end that is rotatably connected to the placement member 14. The limiting part 151 further ensures the stability of the item placed on the placement member 14.

[0033] A connecting wiring channel is provided between the storage component 14, the hinge component 13, and the speaker housing 20. A wire connects the inductor 11 to the electronic control module 40 through the wiring channel. Specifically, corresponding positions of the storage component 14, the hinge component 13, and the speaker housing 20 have pre-reserved adaptation structures (such as holes) to form a through wiring channel. The wire passes through the wiring channel connecting the storage component 14, the hinge component 13, and the speaker housing 20, with one end fixedly connected to the terminal of the inductor 11 inside the storage component 14, and the other end electrically connected to the corresponding interface of the electronic control module 40 inside the mounting cavity 21 of the speaker housing 20. The user can rotate the storage component 14 to a suitable angle by pivoting the hinge component 13. The wiring channel deforms and adapts synchronously with the rotation of the components, and the internal wires always remain within the channel, without affecting the angle adjustment operation. The wiring channel hides and stores the wires connecting the inductor 11 and the control module 40, preventing the wires from being pulled, bent, or worn during the flipping and adjustment, reducing the risk of open circuits and poor contact, and extending the service life of the equipment.

[0034] The speaker housing 20 includes a top cover 22, a middle tube 23, and a base 24. The top cover 22 is pivotally connected to the bracket module 10. One end of the middle tube 23 is connected to the top cover 22, and the other end is connected to the base 24. The speaker module 30 is fixed to the middle tube 23. The electronic control module 40 is mounted on the base 24. Specifically, the top cover 22 and one end of the middle tube 23 are fixedly connected by a snap or thread, and the other end of the middle tube 23 is securely assembled to the base 24 in the same way. The three together form a complete mounting cavity 21. A hole is reserved at the pivot point between the top cover 22 and the hinge 13 for wiring of the inductor 11. The three-section housing facilitates disassembly and assembly, and makes later maintenance (such as replacing the speaker module 30 and repairing the electronic control module 40) more convenient. The speaker module 30 and the electronic control module 40 are placed at opposite ends in the mounting cavity 21 to avoid mutual heat interference during operation and extend the service life of the components. The top cover 22 has multiple through-type slots.

[0035] The electronic control module 40 includes a circuit board 41, LEDs (not shown in the attached diagram), and an amplifier board (not shown in the attached diagram); the LEDs, amplifier board, speaker module 30, and inductor 11 are all electrically connected to the circuit board 41; the circuit board 41 is fixed to the bottom of the speaker housing 20. Specifically, the circuit board 41 is fixed to the base 24 by fasteners, and the LEDs and amplifier board are fixed to preset positions on the circuit board 41 by welding or clipping, forming an integrated electronic control unit. The light-amplifying plate 25 is arranged opposite to the LEDs on the circuit board 41.

[0036] Furthermore, the electronic control module 40 also includes a battery 42, which is disposed on the base 24 and electrically connected to the circuit board 41 to provide power.

[0037] Furthermore, the electronic control module 40 also includes a power interface 43, which is located on one side of the middle cylinder 23 and can provide power to the circuit board 41 via a power connection.

[0038] Furthermore, the electronic control module 40 also includes a button 44, which is located on one side of the middle tube 23 and connected to the circuit board 41. The button 44 can be used to adjust the audio mode and the light of the LED beads.

[0039] The speaker housing 20 also includes a horn-shaped, outwardly flared light-amplifying plate 25. The light-amplifying plate 25 is disposed within the mounting cavity 21 and close to the electronic control module 40. The light-amplifying plate 25 is made of a semi-transparent or transparent material. Specifically, one side of the outer edge of the light-amplifying plate 25 abuts against the base 24, and the other side abuts against the middle tube 23, thus securing the light-amplifying plate 25. The light-amplifying plate 25 is equipped with LED beads, and the circuit board 41 can control the LED beads to emit light. The light is diffused through the semi-transparent / transparent light-amplifying plate 25, achieving soft illumination. Even without illumination, the light-amplifying plate 25 can reflect the sound waves from the speaker module 30, assisting in optimizing the sound field distribution without obstructing heat dissipation of internal components. The light-expanding plate 25 is provided with a wiring post 251 extending toward the upper cover 22, and a wiring hole 252 is provided in the wiring post 251. Specifically, the wire connecting the inductor 11 and the electronic control module 40 passes through the channels of the storage component 14, the hinge component 13, the upper cover 22, the middle cylinder 23 and the wiring hole 252 of the light-expanding plate 25 in sequence, and its two ends are fixedly connected to the terminal of the inductor 11 and the interface of the circuit board 41, respectively. The wire is limited by the wiring post 251 to prevent displacement.

[0040] A connecting post 253 is provided on the side of the light-amplifying plate 25 facing away from the wiring post 251. The connecting post 253 extends toward the base 24 and is connected to the base 24 via a connector. Specifically, the circuit board 41 is provided with holes to allow the connecting post 253 to pass through it and connect to the base 24. On the one hand, the connecting post 253 can limit / position the circuit board 41 to ensure the stability of the circuit board 41. On the other hand, the connecting post 253 can fix the light-amplifying plate 25 to the base 24 to ensure the stability of the structure.

[0041] Furthermore, the bottom of the base 24 is provided with an arc-shaped groove, in which an anti-slip pad 50 is installed. The arc-shaped groove also has a hole for a screw to pass through, through which the screw is threaded onto the connecting post 253 to securely connect the light-amplifying plate 25 to the base 24. The anti-slip pad 50 covers the screw, preventing it from loosening and falling out. The anti-slip pad 50 also provides friction, ensuring the speaker is placed stably.

[0042] The central tube 23 is made of semi-transparent or transparent material. Specifically, the transparent / semi-transparent central tube 23 can display the light and shadow of the internal LED beads, which, together with the diffusion effect of the light diffuser 25, creates ambient lighting, combining practicality and decoration, and adapting to the aesthetic needs of various scenarios.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
