Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
When daily use earphone, if wireless earphone, because left earphone body and right earphone body are relatively independent, have the risk of losing easily, if wired earphone, have left earphone body and right earphone body and the complicated risk of earphone cord wire winding, consequently, in order to accomodate the earphone better, the utility model provides a magnetism inhales earphone.
The magnetic earphone of the present embodiment includes a left earphone body 10 and a right earphone body 20, wherein the left earphone body 10 and the right earphone body 20 both include speakers, and for the purpose of convenience of description, it is noted that the speaker in the left earphone body 10 is a first speaker (not shown), and the speaker in the right earphone body 20 is a second speaker (not shown).
Each loudspeaker comprises a magnet, a diaphragm and a voice coil, the first loudspeaker comprises a first magnet 11, a first diaphragm and a first voice coil 12, and the second loudspeaker comprises a second magnet 21, a second diaphragm and a second voice coil 22.
The first magnet 11 may be an electromagnet or a permanent magnet, and the second magnet 21 may be an electromagnet or a permanent magnet. Preferably, the first magnet 11 and the second magnet 21 are both selected to be permanent magnets in this embodiment.
In the conventional earphone, the structures and the arrangement positions of the first magnet 11, the first diaphragm, and the first voice coil 12 are the same as those of the second magnet 21, the second diaphragm, and the second voice coil 22.
That is, the polarities of the opposite sides of the first magnet 11 and the second magnet 21 are the same, and the magnetic field generated by the current in the first voice coil 12 and the magnetic field generated by the first magnet 11 drive the first diaphragm the same as the magnetic field generated by the current in the second voice coil 22 and the magnetic field generated by the second magnet 21 drive the second diaphragm, that is, the driving frequency and the driving amplitude are the same.
According to the principle of "homopolar repulsion and heteropolar attraction", the polarities of the opposite sides of the first magnet 11 and the second magnet 21 are changed from the same to opposite, so that the left earphone body 10 and the right earphone body 20 are magnetically attracted.
In order to ensure that the earphone can still work normally under the condition of changing the polarity, the magnetic field generated by the current in the voice coil needs to be matched with the magnetic field generated by the magnet.
It is assumed that opposite sides of the first magnet 11 and the second magnet 21 are both S-poles in the conventional earphone.
In the present application, the polarity of the side of the first magnet 11 opposite to the second magnet 21 may be changed to N-pole; alternatively, the polarity of the side of the second magnet 21 facing the first magnet 11 may be changed to the N-pole.
Referring to fig. 2 and fig. 3, they respectively show the structure diagrams of the first magnet 11, the first voice coil 12, the second magnet 21 and the second voice coil 22 in the magnetic suction earphone of this embodiment.
Fig. 2 and 3 respectively show that the polarity of the side of the second magnet 21 opposite to the first magnet 11 changes from S-pole to N-pole, wherein the sides of the first magnet 11 and the second magnet 21 opposite are marked with hatched portions.
For clarity, the wire carrier (not labeled) of the first voice coil 12 and the wire carrier (not labeled) of the second voice coil 22 are also shown in fig. 2 and 3, respectively, with dashed lines.
Since the current in the voice coil is an alternating current, the direction of the current changes in real time, and thus the current shown in fig. 1 and 2 is only the current at a certain moment.
Assuming that the earphone is normally used, at a certain time, the left earphone body 10 has the first magnet 11 as shown in fig. 2 (or fig. 3) and the first voice coil 12 having a current flow in the direction indicated by the arrow in fig. 2 (or fig. 3).
Then the magnetic field generated by the current in the second voice coil 22 needs to be changed accordingly to allow the right earphone body 20 to be used normally. That is, the magnetic field generated by the current in the second voice coil 22 is in the opposite direction to the magnetic field generated by the current in the first voice coil 12.
There are two ways to vary the magnetic field generated by the current in the second voice coil 22: firstly, changing the current direction of the second voice coil 22 without changing the winding direction thereof; second, the winding direction of the second voice coil 22 is changed without changing the current direction thereof.
Referring to fig. 1, the magnetic attraction earphone of the present embodiment further includes a main controller 30 and an audio processing unit 40 connected to the main controller 30, wherein the audio processing unit 40 can realize magnetic attraction of the earphone under the condition of changing the polarity of the opposite side of the second magnet 21 and the first magnet 11; similarly, the earphone magnetic attraction may be realized by changing the polarity of the side of the first magnet 11 facing the second magnet 21.
The audio processing unit 40 can realize the magnetic attraction of the earphone while changing the polarity of the side of the second magnet 21 opposite to the first magnet 11.
In the case where the winding direction of the first voice coil 12 is the same as the winding direction of the second voice coil 22, the audio processing unit 40 controls to change the current direction of the second voice coil 22 to be opposite to the current direction of the first voice coil 12; and in the case that the winding direction of the first voice coil 12 is opposite to the winding direction of the second voice coil 22, the audio processing unit 40 controls to change the current direction of the second voice coil 22 to be the same as the current direction of the first voice coil 12.
Referring to fig. 2, it is shown that the current direction of the second voice coil 22 is changed but the winding direction thereof is not changed, i.e., the winding direction of the second voice coil 22 is the same as the winding direction of the first voice coil 12, and the current direction thereof is opposite to the current direction of the first voice coil 12, as shown by the arrow direction in fig. 2.
Referring to fig. 3, it is shown that the winding direction of the second voice coil 22 is changed without changing the current direction, i.e. the winding direction of the second voice coil 22 (e.g. clockwise winding as shown in fig. 3) is opposite to the winding direction of the first voice coil 12 (e.g. counterclockwise winding as shown in fig. 3), and the current direction is the same as the current direction of the first voice coil 12, as shown by the arrow direction in fig. 3.
The magnetic earphone in this embodiment does not increase or decrease any hardware in the left earphone body 10 and the right earphone body 20, and only by changing the polarity of the opposite side of the second magnet 21 and the first magnet 11 and correspondingly changing the winding direction or current direction of the second voice coil 11, the magnetic field generated by the current in the second voice coil 22 can be matched with the magnetic field generated by the second magnet 21, so that the magnetic attraction of the earphone is realized under the condition that the volume and performance of the earphone are not changed, the earphone is convenient for a user to store and carry, and the user experience is improved; and the left earphone body 10 and the right earphone body 20 which are magnetically attracted together also avoid the earphone from being lost.
The magnetic earphone can be a wireless earphone or a wired earphone.
