Description

Technical Field

[0001] This invention relates to the field of audio technology, and more particularly to a Bluetooth speaker and audio components. Background Technology

[0002] Currently, most existing speakers use wired charging methods such as USB-micro ports and Type-C ports. The charging ports of speakers are basically located at the bottom. When you need to charge and play music at the same time, the charging cable connected to the bottom of the speaker will seriously affect the stability of the speaker, thus affecting the sound output. Moreover, charging and discharging require two hands to plug and unplug the charging cable, which is not convenient. Summary of the Invention

[0003] In order to overcome the shortcomings mentioned in the background art, this application provides a Bluetooth speaker and speaker assembly.

[0004] A Bluetooth speaker includes a housing, wherein an induction coil is disposed inside the housing and the induction coil is electrically connected to a speaker power supply inside the housing.

[0005] As one embodiment, the housing is provided with a charging interface that is electrically connected to the audio power supply, and the housing is provided with a protective cover for protecting the charging interface.

[0006] As one embodiment, the protective cover is a waterproof cover.

[0007] In one embodiment, the housing includes a base plate, the induction coil is close to the base plate and their axes coincide, and the base plate is provided with a magnetic attachment component for attaching the speaker to the wireless charger.

[0008] In one embodiment, the magnetic attraction assembly includes a magnetically conductive shell, a cylindrical magnet, and a non-magnetically conductive sheet. The magnetically conductive shells are arranged in pairs and are fixedly installed on the upper side of the base plate. The cylindrical magnets are movably installed inside the corresponding and paired magnetically conductive shells. The N pole and S pole of the cylindrical magnets are both semi-cylinders. The non-magnetically conductive sheet is located between the corresponding and paired magnetically conductive shells. A gear is provided at one end of the cylindrical magnet extending out of the magnetically conductive shell. A rotating assembly for rotating the gear is provided on the base plate.

[0009] In one embodiment, the rotating assembly includes a rotating ring, which is rotatably disposed on the upper side of the base plate, and the rotating ring is provided with teeth that mesh with the gear.

[0010] As one embodiment, the rotating ring is equipped with a lever to facilitate its rotation.

[0011] As one embodiment, a reset spring for resetting the toggle block is provided between the toggle block and the housing.

[0012] As one embodiment, four magnetic suction components are equidistantly arranged around the axis of the base plate.

[0013] An audio component includes a wireless charger and a Bluetooth speaker. The wireless charger includes a protective case with a power interface. Power coils are provided at the top and bottom of the protective case. The power interface is electrically connected to the power coils. The power coils at the top and bottom of the protective case are wound in opposite directions. Permanent magnets for mutual attraction with the magnetic component and the electronic device are provided at the top and bottom of the protective case, respectively.

[0014] The beneficial effects of this application are: This invention incorporates an induction coil inside the casing, which is electrically connected to the speaker's power supply. This allows the speaker to charge when placed on a wireless charger, thus avoiding interference from the speaker when it is wired.

[0015] Other technical solutions of the present invention can also achieve the following technical effects: By installing a protective cover on the base plate, which is a waterproof cover, the charging port can be blocked to prevent water from entering, thus achieving an IP7 waterproof rating.

[0016] By incorporating a magnetic component on the base plate, the speaker can be magnetically attached to the wireless charger, thereby improving the speaker's stability during charging.

[0017] By setting a pair of magnetically conductive sleeves on the base plate, with a non-magnetic sheet installed between the pairs of magnetically conductive sleeves, and a columnar magnet movably installed inside the magnetically conductive sleeve, the N and S poles of the columnar magnet are both semi-cylinders. A gear is set on the end of the columnar magnet that extends out of the magnetically conductive sleeve. A rotating ring is set on the base plate, and the rotating ring has teeth that mesh with the gear. When the speaker is charging on the wireless charger, the magnetically conductive sleeve is in a magnetized state, and the speaker can be firmly attached to the wireless charger, ensuring the stability of the speaker during charging and preventing the speaker from accidentally separating from the wireless charger. When it is necessary to remove the speaker from the wireless charger, the rotating ring drives the gear to rotate 90° through its teeth, the magnetically conductive sleeve is demagnetized, and the magnetic attraction between the speaker and the wireless charger is reduced. At this time, the user can remove the speaker more easily.

[0018] By setting energized coils and permanent magnets on both the top and bottom of the wireless charger's protective case, the wireless charger can simultaneously wirelessly charge electronic devices and Bluetooth speakers with wireless charging capabilities. Moreover, the wireless charger can also simultaneously attract electronic devices and Bluetooth speakers, ensuring the stability of electronic devices and Bluetooth speakers during charging.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] A Bluetooth speaker, such as Figure 1 and Figure 2As shown, the device includes a housing 1. Inside the housing 1, there is an induction coil 2 and a speaker power supply. The induction coil 2 is electrically connected to the speaker power supply. The center point of the induction coil 2 is close to the axis of the housing 1. The principle of the wireless charger charging the speaker is as follows: After the wireless charger is connected to the power supply, current flows through the coil inside the wireless charger, generating an alternating magnetic field around the coil. The induction coil 2, located within the alternating magnetic field, continuously cuts the magnetic field lines, causing the induction coil 2 to generate an induced current. This current enters the speaker power supply, achieving the charging effect. Wireless charging technology is a relatively mature technology among existing technologies and will not be elaborated further below.

[0023] In one embodiment, such as Figure 2 and Figure 3 As shown, the housing 1 is provided with a charging interface that is electrically connected to the audio power supply, and the housing 1 is provided with a protective cover 3, which is used to protect the charging interface.

[0024] In one embodiment, the protective cover 3 is a waterproof cover. The protective cover 3 can be made of rubber. The protective cover 3 can block the charging interface to prevent water from entering the charging interface. In addition, the internal circuit board and the bottom of the housing 1 are also provided with a silicone waterproof ring for sealing, thereby preventing water molecules from seeping in and achieving IP7 waterproof rating.

[0025] In one embodiment, such as Figure 3 As shown, the housing 1 includes a base plate 101, an induction coil 2 is close to the base plate 101 and their axes coincide, and a magnetic attraction component 4 is provided inside the housing 1. The magnetic attraction component 4 can be a permanent magnet. The permanent magnet is installed on the upper side of the base plate 101 and the permanent magnet can be ring-shaped. A protective cover 3 is installed on the base plate 101. The magnetic attraction component 4 is used to make the speaker attach to the wireless charger.

[0026] In one embodiment, such as Figures 4-7As shown, the magnetic attraction assembly 4 includes a magnetically conductive housing 401, a columnar magnet 402, and a non-magnetically conductive sheet 403. The magnetically conductive housings 401 are arranged in pairs and are fixedly installed on the upper side of the base plate 101. The magnetically conductive housings 401 can be made of silicon steel. The non-magnetically conductive sheet 403 is installed between two adjacent magnetically conductive housings 401. The non-magnetically conductive sheet 403 can be made of copper. The non-magnetically conductive sheet 403 and the two adjacent magnetically conductive housings 401 form a cylindrical cavity. The cylindrical magnet 402 is movably installed within the cylindrical cavity. The cylindrical magnet 402 can rotate within the cavity and can be pulled directly out when needed. The axis of the cylindrical magnet 402 is parallel to the horizontal plane. One half of the cylindrical magnet 402 is the N pole, and the other half is the S pole. The N and S poles of the cylindrical magnet 402 are two symmetrical semi-cylinders. In the initial state, the cylindrical magnet 402 is divided into N and S poles by a vertical plane. At this time, the magnetic field lines between the N pole and the S pole are blocked by the copper sheet. In order to form a closed loop, the magnetic field lines can only leave from the magnetically conductive sleeve 401, pass through the air to bypass the obstruction of the copper sheet, and return to the magnetically conductive sleeve 401, finally reaching the S pole to form a closed loop. At this time, the magnetically conductive sleeve 401 is in a magnetized state, causing the magnetically conductive sleeve 401 to generate magnetism itself. A gear 404 is installed at one end of the columnar magnet 402 that extends out of the magnetically conductive sleeve 401. The base plate 101 is provided with... The rotating assembly used to rotate the gear 404, when driving the corresponding cylindrical magnet 402 to rotate 90° via the gear 404, divides the cylindrical magnet 402 into N and S poles by a horizontal plane. At this time, the magnetic field lines of the cylindrical magnet 402 from the N pole to the S pole are not blocked by the copper sheet and form a closed circuit within the magnetically conductive sleeve 401. Due to the strong magnetic permeability of silicon steel, the magnetic field lines of the cylindrical magnet 402 are difficult to detach from the magnetically conductive sleeve 401, causing the magnetically conductive sleeve 401 to demagnetize. The principle of magnetization and demagnetization of the magnetically conductive sleeve 401 can be referred to in the existing technology of magnetic bases, and will not be elaborated further below.

[0027] In one embodiment, such as Figure 5 and Figure 6 As shown, the rotating assembly includes a rotating ring 501, which is rotatably mounted on the upper side of the base plate 101. The upper side of the rotating ring 501 is provided with teeth that mesh with the gear 404. When the rotating ring 501 rotates, the teeth on the rotating ring 501 drive the gear 404 to rotate, thereby switching the magnetization and demagnetization states of the magnetic housing 401.

[0028] In one embodiment, such as Figure 4 and Figure 5 As shown, a lever 502 is installed on the side of the rotating ring 501. The lever 502 is provided with anti-slip texture. By pushing the lever 502, the user can more easily rotate the rotating ring 501 and switch the magnetic state of the magnetic component 4.

[0029] In one embodiment, such as Figure 4 As shown, a return spring 503 is provided between the lever 502 and the housing 1, with both ends of the return spring 503 fixedly connected to the lever 502 and the housing 1 respectively. When the speaker is charging on the wireless charger, the magnetic housing 401 is in a magnetized state, allowing the speaker to be firmly attached to the wireless charger, ensuring the stability of the speaker during charging and preventing the speaker from accidentally separating from the wireless charger. When it is necessary to remove the speaker from the wireless charger, the user can first move the lever 502. At this time, the return spring 503 is compressed under the squeezing action of the lever 502 and the housing 1, and the return spring 503 stores force. The lever 502 drives the rotating ring 501 to rotate, and the rotating ring 501 drives the gear 404 to rotate through its teeth. When the gear When 404 drives the cylindrical magnet 402 to rotate about 90°, the magnetic field lines of the cylindrical magnet 402 are almost entirely located inside the magnetic housing 401. The magnetic housing 401 is demagnetized, which reduces the magnetic attraction between the magnetic housing 401 and the wireless charger. At this time, the user can remove the speaker more easily. After removing the speaker, the user can release the lever 502. Under the action of the return spring 503, the lever 502 drives the rotating ring 501, gear 404 and cylindrical magnet 402 to reset. After resetting, the magnetic housing 401 is in a magnetized state.

[0030] In one embodiment, such as Figure 5 As shown, multiple magnetic components 4 are equidistantly distributed around the axis of the base plate 101. Multiple magnetic components 4 can improve the stability of the speaker on the wireless charger.

[0031] In one embodiment, such as Figure 5 As shown, there are four magnetic components 4. The four magnetic components 4 are connected to form a square. The number of magnetic components 4 should not be too many, so that the speaker can be stably attached to the wireless charger while the non-magnetic sheet 403 does not affect the charging efficiency of the speaker. This avoids the problem that too many non-magnetic sheets 403 will seriously affect the induction coil 2 to receive the magnetic field signal, thereby causing a serious reduction in charging efficiency.

[0032] An audio component, such as Figure 1 , Figure 4 , Figure 8 and Figure 9As shown, the device includes a wireless charger 6 and a Bluetooth speaker. The Bluetooth speaker includes an induction coil 2 and a magnetic component 4, but its structure is not limited to these and may include other components. The wireless charger 6 includes a protective shell 601 with a circular cross-section. The diameter of the protective shell 601 corresponds to the bottom diameter of the Bluetooth speaker, allowing the bottom surface of the Bluetooth speaker to fully conform to the protective shell 601. The protective shell 601 has a power interface for connecting to an external power source. Power coils 602 are located at the top and bottom of the protective shell 601, and the power interface is electrically connected to the power coils 602. A circuit board is located inside the protective shell 601, and the circuit board is connected to the power coils 602. The circuit board has an electrical interface for connection. LEDs are connected to the circuit board via leads. These LEDs can be embedded in the upper and lower edges of the protective housing 601, and their light can be exposed through external holes in the protective housing 601. Alternatively, the upper and lower edges of the protective housing 601 can be made transparent, allowing the LEDs to display their light without the external holes. Multiple LEDs can be arranged equidistantly around the axis of the protective housing 601, or the LEDs can be arranged in a ring shape, with one ring-shaped LED on each of the upper and lower edges of the protective housing 601. The energizing coils 602 at the top and bottom of the protective housing 601 are wound in opposite directions. Figure 9 Taking the direction shown as an example to explain the winding direction of the energized coil 602, the energized coil 602 at the top of the protective shell 601 is wound clockwise, and the energized coil 602 at the bottom of the protective shell 601 is wound counterclockwise. The top and bottom of the protective shell 601 are respectively provided with permanent magnets 603 for mutual attraction with the magnetic component 4 and electronic devices. The electronic devices can be mobile phones or tablets that can be wirelessly charged. The magnetic poles of the two sets of permanent magnets 603 inside the protective shell 601 are in the same direction. For example, the two permanent magnets 603 at the top and bottom of the protective shell 601 are both with an upper S pole and a lower N pole, or both are both with an upper N pole and a lower S pole, so that the Bluetooth speaker of the present invention and the wireless charging mobile phone on the market can be attracted to the upper and lower sides of the wireless charger 6. By setting two energized coils 602 inside the protective shell 601, the wireless charger 6 can wirelessly charge the Bluetooth speaker and the wireless charging mobile phone of the present invention at the same time. Moreover, when the Bluetooth speaker and the mobile phone are charging at the same time, by tilting the mobile phone upright, the Bluetooth speaker and the wireless charger 6 can be used as a mobile phone stand, making it convenient for the user to view the mobile phone screen.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
