Further, as shown in fig. 2, the earphone box 100 provided by the embodiment of the present disclosure may further include a box cover 140 and a power supply unit 160. The cover 140 may be coupled to the case body 110, and the cover 140 may be used to cover the accommodating portion 111 of the case body 110, so as to prevent the earphone placed in the accommodating portion 111 from being lost or damaged. The cover 140 may be provided at one side of the opening of the receiving portion 111 of the case body 110. The power supply unit 160 is used for supplying power when the headset is charged, and the power supply unit 160 may include a second power source 161 and a charging circuit, through which an electrical signal of the second power source 161 is transmitted to the headset during charging. The power supply unit 160 may be disposed at a side of the case body 110 away from the opening of the accommodating part 111.
The following will describe each part of the earphone box provided by the embodiment of the present disclosure in detail:
the case 110 may be in the shape of a cuboid, sphere, hemisphere, or ellipsoid. The case 110 is provided with a receiving portion 111 having an opening, and the receiving portion 111 receives the earphone. Since the number of the earphones is usually two, the accommodating portion 111 includes a first accommodating portion and a second accommodating portion disposed on the case body 110, a magnetron unit 120 is disposed on a sidewall of the first accommodating portion, and a magnetron unit 120 is disposed on a sidewall of the second accommodating portion. In practical applications, one or two earphones can be disposed in the same accommodating hole.
The shape of the containing hole can be matched with that of the earphone. For example, the earphone may include an earplug 211 and a body 212, and an earplug 211 receiving region and a body 212 receiving region may be disposed in the corresponding receiving holes. The receiving area of the ear plug 211 is disposed at an end close to the opening, the receiving area of the body 212 is disposed at an end close to the power supply unit 160, and the receiving areas of the ear plug 211 and the body 212 are communicated with each other. The cross-sectional area of the receiving area of the earplug 211 is larger than the cross-sectional area of the receiving area of the body 212. The axes of the first and second receptacles may be parallel.
The cover 140 is disposed at one side of the opening of the receiving portion 111 of the case body 110, and the cover 140 can be hinged (e.g., connected by a hinge or a hinge) to the case body 110. The box body 110 and the box cover 140 may further be provided with a buckle structure and a spring, the spring may be disposed on the connecting shaft, and the buckle structure is disposed at one end of the box body 110 or the box cover 140 away from the connecting shaft.
The material of the case body 110 and the case cover 140 may be plastic, metal, or glass. The materials of the case body 110 and the cover 140 may be the same or different, for example, the materials of the case body 110 and the cover 140 may be both plastic, or the material of the case body 110 may be glass, and the material of the cover 140 may be plastic.
When the case 110 includes the first accommodating portion and the second accommodating portion, the magnetic control units 120 are respectively disposed at corresponding positions of the first accommodating portion and the second accommodating portion. When each magnetic control unit 120 corresponds to one earphone, that is, when the corresponding earphone with the magnetic member 220 is inserted into the containing hole, the magnetic control unit 120 corresponding to the containing hole is triggered. However, since the two accommodating holes are close to each other, the magnetic fields of the two earphones may affect each other, which results in inaccurate detection results, for example, only one earphone enters the accommodating hole, and the magnetic field generated by the magnetic member 220 of the earphone affects both the magnetic control units 120 corresponding to the two accommodating holes. In order to solve this problem, a magnetic shield layer 150 may be provided on the case body 110, the magnetic shield layer 150 being provided between the first accommodating part and the second accommodating part.
The magnetic shielding layer 150 may be embedded in the case body 110 and between the first accommodating portion and the second accommodating portion in the case body 110. The magnetic shielding layer 150 is used for shielding or weakening a magnetic field, so that the magnetic field on one side of the magnetic shielding layer 150 is prevented from influencing a magnetic control switch on the other side of the magnetic shielding layer 150, and the magnetic control switch is prevented from being triggered by mistake. The magnetic shield layer 150 may be a metal mesh such as an iron mesh or a copper mesh, etc. Or the magnetic field can be shielded by an electrified conductor, when the magnetic control unit 120 is triggered, the magnetic shielding layer 150 is electrified, and at this time, the on-off state of the magnetic control unit 120 on both sides of the magnetic shielding layer 150 is continuously detected. When the magnetic shielding layer 150 is powered on and the magnetic control unit 120 is still in the triggered state, the earphone with the correct detection result is considered to be placed in the box. When the magnetic shielding layer 150 is powered on and the magnetic control unit 120 is still disconnected, the earphone with the wrong detection result is considered not to be put into a box.
As shown in fig. 4, the magnetic control unit 120 may include a first power source 121 and a magnetic sensitive switch 122, one end of the magnetic sensitive switch 122 is connected to the first power source 121, the other end of the magnetic sensitive switch 122 is connected to the processing unit 130, when the magnetic sensitive switch 122 is in a magnetic field, the magnetic sensitive switch 122 is turned on, and the first power source 121 outputs a trigger signal to the processing unit 130.
The first power source 121 may be connected to the second power source 161, the second power source 161 may be a battery provided to the case 110, and the first power source 121 may include a voltage-reducing circuit 1211. When detecting whether the magnetron unit 120 is turned on, only a small voltage or current is required. Therefore, in order to avoid the influence of the impact of the large current or the voltage signal on the electrical devices such as the processing unit 130 and the like, the voltage of the signal output by the battery (the second power source 161) can be reduced through the voltage reduction circuit (the first power source 121), so that the energy consumption can be reduced, and the duration of the earphone box is facilitated.
The voltage-reducing circuit 1211 may be a charge pump voltage-reducing circuit or a BUCK circuit. The charge pump step-down circuit can step down the voltage output by the battery by times. For example, the charge pump step-down circuit may implement a 2-fold step-down or a 4-fold step-down, etc.
As shown in fig. 6, the 2-fold buck charge pump may include a first transistor M1, a second transistor M2, a third transistor M3, a fourth transistor M4, a first capacitor C1, and a second capacitor C2. A first terminal of the first transistor M1 is connected to the second power source 161, and a control terminal of the first transistor M1 is connected to the processing unit 130; the first end of the second transistor M2 is connected to the second end of the first transistor M1, and the control end of the second transistor M2 is connected to the processing unit 130; a first end of the third transistor M3 is connected to the second end of the second transistor M2, and a control end of the third transistor M3 is connected to the processing unit 130; a first terminal of the fourth transistor M4 is connected to the second terminal of the third transistor M3, a control terminal of the fourth transistor M4 is connected to the processing unit 130, and a second terminal is grounded; a first end of the first capacitor C1 is connected to the second end of the first transistor M1, and a second end of the first capacitor C1 is connected to the second end of the third transistor M3; the first terminal of the second capacitor C2 is connected to the second terminal of the second transistor M2, and the second terminal of the second capacitor C2 is grounded.
In the write phase, the processing unit 130 controls the first transistor M1 and the third transistor M3 to be turned on, and controls the second transistor M2 and the fourth transistor M4 to be turned off, so as to charge the first capacitor C1 and the second capacitor C2;
in the output stage, the processing unit 130 controls the first transistor M1 and the third transistor M3 to turn off, and controls the second transistor M2 and the fourth transistor M4 to turn on, and outputs the reduced-voltage charging signal.
Of course, in practical applications, the step-down charge pump may also be other step-down multiples, and the embodiment of the disclosure is not limited thereto.
Certainly, in practical applications, the magnetic control unit 120 may also be directly connected to the second power source 161 (battery), and the second power source 161 directly supplies power to the magnetic control unit 120, so that the number of devices in the earphone box can be reduced, and the cost of the earphone box can be controlled.
As shown in fig. 5, the earphone box provided in the embodiment of the present disclosure may further include a switching circuit 170 and an earphone charging circuit 162, where the earphone charging circuit 162 is used to charge the earphone. The switching circuit 170 is connected to the voltage reducing circuit 170, the magnetic control unit 120, the second power source 161 and the earphone charging circuit 162. The switching circuit 170 switches the voltage reducing circuit 1211 to be conducted with the magnetic control unit 120 when the earphone is in the box detection mode, and the switching circuit 170 switches the voltage reducing circuit 1211 to be conducted with the earphone charging circuit 162 when the earphone is in the charging mode, or switches the second power source 161 to be directly conducted with the earphone charging circuit 162 when the earphone is in the charging mode. Therefore, the voltage reduction circuit 1211 is shared in the earphone in-box detection and battery charging modes, the number of electronic devices is saved, and the cost of the earphone box is reduced.
As shown in fig. 3, the magnetic sensitive switch 122 includes: the first magnetizable shrapnel 1221 and the second magnetizable shrapnel 1222, the second magnetizable shrapnel 1222 and the first magnetizable shrapnel 1221 are arranged oppositely, the first magnetizable shrapnel 1221 and the second magnetizable shrapnel 1222 are normally open, and when the magnetic sensitive switch 122 is in a magnetic field, the first magnetizable shrapnel 1221 and the second magnetizable shrapnel 1222 are closed.
The first magnetizable elastic piece 1221 and the second magnetizable elastic piece 1222 are in a non-magnetized state in a non-magnetic field environment, and the first magnetizable elastic piece 1221 and the second magnetizable elastic piece 1222 are in a normally open state. When in a magnetic field environment, the first magnetizable clip 1221 and the second magnetizable clip 1222 are magnetized, and the polarity of the first magnetizable clip 1221 is opposite to the polarity of the second magnetizable clip 1222. The first magnetizable elastic piece 1221 and the second magnetizable elastic piece 1222 are magnetized and then attracted to each other by magnetic force, and the magnetic sensitive switch 122 is closed. When the magnetic field disappears (the earphone moves out), the first magnetizable elastic piece 1221 and the second magnetizable elastic piece 1222 are demagnetized, and the magnetic sensitive switch 122 is turned off.
The box body 110 is provided with a receiving cavity, and the first magnetizable elastic sheet 1221 and the second magnetizable elastic sheet 1222 are disposed in the receiving cavity. The holding cavity is a sealed cavity and is filled with inert gas or is a vacuum holding cavity. By arranging the accommodating cavity on the box body 110, the first magnetizable elastic sheet 1221 and the second magnetizable elastic sheet 1222 are arranged in the accommodating cavity, so that the need of separately manufacturing the shell of the magnetic control unit 120 is avoided, the space of the box body 110 can be saved, and the miniaturization of the earphone box is facilitated. The holding cavity is a sealed cavity and is filled with inert gas or is a vacuum holding cavity.
When the earphone 200 includes the ear plug 211 and the body 212, the housing 110 has an ear plug 211 receiving area and a body 212 receiving area, and there is a step between the ear plug 211 receiving area and the body 212 receiving area. Namely, the side walls of the first accommodating part and the second accommodating part are provided with steps. A receiving cavity for receiving the magnetic sensitive switch 122 may be provided in the step.
For example, when the earphones 200 are stored in the earphone case 100, the earplugs 211 of the two earphones may be disposed opposite to each other, and in this case, the step in the first accommodating portion may be disposed at a side of the first accommodating portion close to the second accommodating portion, and the step in the second accommodating portion may be disposed at a side of the second accommodating portion close to the first accommodating portion. That is, the two magnetic switches 122 are disposed at the middle position of the earphone box, and since the two magnetic switches 122 are close to each other, the magnetic shielding layer 150 needs to be disposed between the two magnetic switches 122.
Alternatively, when the earphones 200 are stored in the earphone case 100, the earplugs 211 of the two earphones may be disposed oppositely, and in this case, the step in the first accommodating portion may be disposed on a side of the first accommodating portion away from the second accommodating portion, and the step in the second accommodating portion may be disposed on a side of the second accommodating portion away from the first accommodating portion.
Alternatively, when the earphones 200 are stored in the earphone case 100, the earplugs 211 of the two earphones may face in the same direction (the front direction of the earphone case or the back direction of the earphone case), and the steps in the first accommodating portion and the steps in the second accommodating portion may be located on the same side of the earphone case.
Of course, in practical applications, the magnetic sensitive switch 122 may also include a packaging case, and the first magnetizable clip 1221 and the second magnetizable clip 1222 may be packaged in the packaging case. The two ends of the package housing may be provided with a first conductive pin, and the first conductive pin is connected to the first magnetizable elastic sheet 1221 and the second magnetizable elastic sheet 1222, respectively. At this time, the case 110 may be provided with a mounting portion for mounting the magnetic switch 122. Two second conductive pins matched with the first conductive pins are arranged on the mounting part, wherein one second conductive pin is connected with the second power supply 161 (the output end of the step-down power supply), and the other second conductive pin is connected with the processing unit 130.
The second power source 161 and the processing unit 130 are disposed on the side of the box body 110 away from the opening of the accommodating portion 111, the box body 110 is provided with a first wire hole 112 and a second wire hole 113, the first wire hole 112 extends from the magnetron unit 120 to the second power source 161, and the second wire hole 113 extends from the magnetron unit 120 to the processing unit 130.
Illustratively, the first wire hole 112 may extend from a second conductive pin to the second power source 161, and the second wire hole 113 extends from another magnetron unit 120 to the processing unit 130. And wires can be arranged in the first wire routing hole and the second wire routing hole so as to be connected with corresponding electrical components.
