Detailed Description
Referring to fig. 1 to 16, the present embodiment provides a magnetic suspension type vibration isolation device, including a magnetic suspension system 1 and a speaker module 2, where the magnetic suspension system 1 is used to keep the speaker module 2 suspended; the magnetic levitation system 1 includes a first magnetic body 110, a second magnetic body 120, and a third magnetic body 130; the magnetization directions of the first magnetic body 110 and the second magnetic body 120 are the same; the third magnetic body 130 is located between the first magnetic body 110 and the second magnetic body 120, and a floating active region 140 is located between the third magnetic body 130 and the first magnetic body 110 and the second magnetic body 120; the third magnetic body 130 has a magnetization direction opposite to the magnetization directions of the first and second magnetic bodies 110 and 120; the speaker module 2 is provided with a connecting part connected with the third magnetic body 130; at least one of the first magnetic body 110, the second magnetic body 120, and the third magnetic body 130 is an electromagnet.
The loudspeaker works to vibrate, the emitted energy is transmitted by waves, and the propagation characteristic of the waves is that a front mass point drives a rear mass point to vibrate in the medium in sequence along the propagation direction of the waves; forming energy waves which are diffused towards the periphery of the loudspeaker by taking the loudspeaker as a wave source; when the wave is transmitted to such a medium in the air, it becomes a sound wave of a sound that the human ear can hear; when waves are transmitted to solid media such as a cabinet, a shell and other electronic components which are connected with the loudspeaker in a mounting way, mechanical vibration, shaking and noise which are not expected by a user can affect the using experience of the user.
Because the loudspeaker vibrates to produce the motive force when broadcasting the audio frequency, when the weak magnetic force that the electro-magnet of the magnetic levitation system 1 is electrified to produce causes the magnetic part of the magnetic levitation system 1 each other repulsion force is smaller, namely the loudspeaker die set is because of the sounding vibration of the loudspeaker, make the loudspeaker die set 2 under the lift of the magnetic levitation system 1, when it is easier to move about, the compliance of the levitation system is big at this moment, the resonant frequency of the system is small, can avoid vibrating to spread outwards through the reaction force effectively, the die set amplitude is great, this kind of situation is the phenomenon produced when the electric current to the electro-magnet is appropriate small current;
when the suspension system compliance is little, the electro-magnet of magnetic suspension system 1 lets in the heavy current promptly, produces the powerful magnetic field, promotes to lift rigidity to the speaker module, when making the speaker module be difficult to remove, and the vibration isolation performance to the speaker module is relatively poor under this kind of condition, but speaker broadcast efficiency is higher. Therefore, the device adjusts the value of the direct current electrified to the electromagnet in the magnetic suspension system 1 in real time correspondingly according to the frequency and amplitude of the audio signal aiming at audio playing, when the frequency and amplitude of the input signal enable the loudspeaker to vibrate greatly, the direct current supplied to the electromagnet is reduced, the magnetic force of the electromagnet is controlled to keep the loudspeaker module suspended, when the frequency and amplitude of the input signal enable the loudspeaker to vibrate less, the direct current supplied to the electromagnet is increased, the electromagnet is controlled to output strong magnetic force to suspend the loudspeaker module, namely the compliance of the suspension system is controlled, and the optimal audio playing effect is achieved.
Further, when the loudspeaker is in standby, the small current direct current which supplies power to the electromagnet controls the magnetic force of the electromagnet to keep the loudspeaker module suspended.
When the loudspeaker is in standby, the loudspeaker module is kept in a suspension state, otherwise, the electromagnet is powered off, and when the electromagnet and the permanent magnet are arranged in the magnetic suspension system 1, the permanent magnet can adsorb the loudspeaker module to any side; when the magnetic suspension system 1 is provided with electromagnets, the loudspeaker module 2 falls down along the gravity or external force direction under the action of gravity and is not suspended again;
therefore, the magnetic suspension system 1 is deviated, and when the power is switched on again, the permanent magnet or the electromagnet in the magnetic suspension system 1 cannot fall into the magnetic field trap, so that the loudspeaker module 2 cannot be suspended successfully, or the loudspeaker module 2 is deviated in suspension, so that the vibration isolation function is influenced;
when the speaker standby is cut off the power supply, still make the electromagnet in magnetic suspension system 1 and last the circular telegram, and the direct current of this circular telegram is little to only can make magnetic force and repulsion that the electromagnet produced can overcome speaker module gravity to guarantee that the speaker module is not off normal, speaker module suspension part still falls into the design range, when the speaker module need output audio frequency during operation, can continue normal suspension after the speaker module circular telegram.
Because the speaker module of different specifications can have different weight, receives different gravity, consequently leads to the electric current size that obtains the electromagnet in the magnetic levitation system 1 and need pass through the check and calculate the affirmation, makes the magnetic force that the electromagnet produced and repulsion can overcome speaker module gravity to guarantee the current minimum of speaker module off normal.
This magnetic levitation formula vibration isolation device makes speaker module 2 suspend through magnetic levitation system 1, it rises speaker module 2, will originally directly with speaker module 2 and the inside inner wall connection of electronic product or adjust for speaker module 2 no longer contacts through traditional vibration isolation packing ring 5 and electronic product internal connection's face contact, like this at speaker module 2 work sound production, when vibration takes place, break through the restriction that 5 compliance complete dependence material physical properties of vibration isolation packing ring of current design, greatly avoided the transmission of speaker module 2 vibration to electronic product box or casing, neighbouring speaker module 2 other parts, avoid arousing the unexpected vibration of user.
