Embodiment
The utility model is described in further detail with reference to embodiments, but the utility model is not limited to these implementations Example.
A kind of headphone for supporting wireless charging includes inverted T-shaped stent, and the inverted T-shaped stent is main Including base 1 and supporting rod 2;The base 1 and supporting rod 2 are connected;Two magnetic inductors are installed in the base 1, point Wei not the first magnetic inductor and the second magnetic inductor;First transmitting coil 3 is installed in first magnetic inductor, described second Second transmitting coil 4 is installed in magnetic inductor;First transmitting coil, the 3 place plane is parallel to the ground, second hair 4 place plane of ray circle is parallel to the ground.Above-mentioned setting is to match use with the headphone of each support wireless charging When, each transmitting coil is used in parallel with corresponding receiving coil, obtains the magnetic flux of maximum as far as possible, and then is obtained as far as possible most Big magnetic coupling amount.
A kind of headphone for supporting wireless charging, has further included U-shaped head beam 6 and 2 power supply modules;During charging, institute U-shaped head beam 6 is stated to ride upon on the supporting rod 2;2 power supply modules are respectively the first power supply module and the second power supply module;Institute One end that the first power supply module is installed on U-shaped head beam 6 is stated, second power supply module is installed on the other end of U-shaped head beam 6; First receiving coil 7 is installed in first power supply module, the second receiving coil 8 is installed in second power supply module; First receiving coil, the 7 place plane is parallel to the ground, and the 8 place plane of the second receiving coil is parallel to the ground.Charging When, the magnetic induction line energy almost all that the first transmitting coil 3 produces passes through the first receiving coil 7, the sense that the second transmitting coil 4 produces Line energy almost all is answered to pass through the second receiving coil 8, it is this to be arranged in parallel, charging distance can be increased and improve charge efficiency.
It were it not for and set 5,1 receiving coil of magnetic isolation plate to receive from the transmitting coil of 2 even more than 2 Magnetic induction line, the magnetic induction line from 2 or the transmitting coil of more than 2 are offset, and reduce the electromotive force that receiving coil can receive, magnetic Coupling effect is very poor, causes charge efficiency low.It can be seen that, it is necessary to each set transmitting coil and receiving coil are separated into use, that is, sent out Ray circle can be matched with corresponding transmitting coil, separate use with other set of transmitting coils and receiving coil, mutually not Interference.The utility model is provided with magnetic isolation plate 5 in supporting rod 2, and the magnetic isolation plate 5 runs through whole supporting rod 2, and magnetic isolation plate will be each The complete transmitting coil used and receiving coil separate so that often covering transmitting coil and receiving coil can be used alone, and not influence Other set of transmitting coils and receiving coil.As it can be seen that the setting of magnetic isolation plate 5, helps to improve charge efficiency.User can also root According to demand, more set of transmitting coils and receiving coil, and corresponding extension supporting bar are added, magnetic isolation plate is set in supporting rod 5, greater number of headphone can be supported to charge.
