Embodiment

[0026] This embodiment provides a magnetic levitation bluetooth speaker, which suspends the speaker above the base 1 as a suspension body 4, so as to avoid resonance caused by contact with objects during audio playback, thereby affecting the sound quality.

[0027] Such as image 3 As shown, the magnetic levitation bluetooth speaker with adjustable levitation height includes a magnetic levitation base 1 and a speaker. Wherein the coil 2 is fixed on the coil assembly 3, the coil assembly 3 is fixed on the suspension body 4, the coil assembly 3 is provided with a Hall sensor, the base 1 includes an annular permanent magnet substantially horizontally arranged in the base, and an annular permanent magnet located in the base The four solenoid coils of the inner ring and the horizontal control unit connected to the solenoid coils. When the suspension 4 deviates from the reference position, it is controlled to return to the reference position.

[0028] In this embodiment, a method ...

Abstract

The invention discloses a magnetic suspension device. The magnetic suspension device comprises a base and a suspension body, wherein the base is internally provided with an annular magnet; an electromagnetic coil is arranged in the annular magnet; the electromagnetic coil is connected with a control device; the suspension body comprises a power supply, a magnetic field sensing circuit, a circuit control unit and a single electromagnetic coil; the power supply supplies power to the magnetic field sensing circuit, the circuit control unit and the electromagnetic coil; the magnetic field sensing circuit and the electromagnetic coil are connected to the circuit control unit respectively; the magnetic field sensing circuit is used for detecting a magnetic field direction in the base in a movement process of the suspension body, and transmitting a signal to the circuit control unit; and the circuit control unit is used for regulating a current direction of the electromagnetic coil according to the received signal so that the magnetic field direction of the electromagnetic coil and the magnetic field direction of the base keep consistent. Compared with an existing magnetic suspension system, the magnetic field direction and size of the circuit can be controlled through the electromagnetic coil, and the storage difficulty can be reduced; and the suspension height of the suspension body is adjustable.

Description

technical field [0001] The invention relates to a magnetic levitation device, in particular to a magnetic levitation device capable of adjusting the magnetic field direction and levitation height of a levitation body. Background technique [0002] Existing magnetic levitation products basically use manual methods to store suspended matter. The base of the magnetic levitation system is generally composed of a ring magnet and an electromagnetic adjustment coil. The direction of the magnetic field in a predetermined area of ​​the inner circle of the ring is the same as that of the suspension. However, when the suspension is located in the area between the inner ring and the outer ring of the ring magnet, the direction of the magnetic field of the suspension itself is opposite to the direction of the magnetic field at this time, and the base will generate suction to the suspension, which will affect the hand feeling during placement. , making the operability of the experience d...
