headphone system.

Background Technology

Earphones are one of the commonly used devices for playing music, especially headphones

are becoming more and more popular because of their sound quality. Conventional headphones

are usually connected to devices such as mobile phones through audio cables. As most mobile

phones started to cancel the 3.5mm interface, the frequency of using headphones connected to

audio sources through wireless technology is increasing. However, most wireless headphones are

still charged through a cable, users often forget to connect the cable to charge their headphones,

and the headphones cannot be turned on due to low battery.

An objective of the present disclosure is to provide a headphone system with simplified

charging operation.

In order to achieve the above objective, the present disclosure provides a headphone system,

including a headphone body and a headphone base. The headphone body is equipped with a

battery therein, and includes two earpieces and a head band connecting the two earpieces. One of

the earpieces is provided with a receiving coil module for wireless charging which is connected

to the battery. The headphone base includes a supporting plate, and a positioning block and a

transmitting coil module for wireless charging arranged on the supporting plate. The positioning

block is located above the transmitting coil module for wireless charging so that the receiving

coil module and the transmitting coil module for wireless charging are paired with each other

when the head band is placed on the positioning block, thereby realizing wireless charging.

Further, an upper surface of the positioning block is in an arc shape matching a shape of the

head band.

Further, the supporting plate also includes a fixing block located above the positioning block,

and surfaces of the fixing block and the positioning block facing each other are both matched

with the shape of the head band, so as to form a groove with a shape matching the shape of the

head band between the fixing block and the positioning block.

Further, the headphone base also includes a case body located below the positioning block,

and the transmitting coil module for wireless charging is accommodated in the case body.

Further, the transmitting coil module for wireless charging includes a transmitting coil, and a

charging control circuit connected to an external power source through a charging cable, the

transmitting coil is connected to the charging control circuit.

Further, a charging indicator is provided on the headphone base, and the charging indicator

is connected with the charging control circuit to indicate a charging status.

Compared with the prior art, the headphone system of the present disclosure is provided

with a receiving coil module for wireless charging in an earpiece of the headphone body, and a

transmitting coil module for wireless charging on the supporting plate of the headphone base.

When charging is required, the head band of the headphone body is placed on the positioning

block, and induction charging is carried out through pairing of the receiving coil module and the

transmitting coil module for wireless charging, thereby realizing wireless charging of the

headphone. This does not require any cable, and is easy to operate, which may avoid the

situation that users forget to connect the headphone with the cable to charge the headphone, and

the headphone cannot be turned on due to low battery.

The present disclosure will become clearer through the following description in conjunction

with the accompanying drawings. These drawings are used to explain embodiments of the

present disclosure.

Brief Description of the Drawings

Fig. 1 is a partially cross-sectional view of a headphone system according to an embodiment

of the present disclosure.

Detailed Description

The technical solutions in the embodiments will be clearly and completely described below

in conjunction with the drawings in the embodiments of the present disclosure. Similar reference

numbers in the drawings represent similar components. Obviously, the embodiments to be

described below are merely a part of the embodiments of the present disclosure, rather than all

the embodiments. Based on the embodiments of the present disclosure, all other embodiments

obtained by a person of ordinary skill in the art without creative work shall fall within the scope

of protection of the present disclosure.

Referring to Fig. 1, Fig. 1 is a partially cross-sectional view of a headphone system 1

according to an embodiment of the present disclosure. In the embodiment shown in the

accompanying drawing, the headphone system 1 includes a headphone body 10 and a headphone

base. The headphone body 10 is equipped with a battery therein, and includes two earpieces 101

and a head band 102 connecting the two earpieces 101. One of the earpieces 101 is provided

with a receiving coil module for wireless charging 103 which is connected to the battery. The

headphone base includes a supporting plate 201, and a positioning block 2022 and a transmitting

coil module for wireless charging 203 arranged on the supporting plate 201. The positioning

block 2022 is located above the transmitting coil module for wireless charging 203 so that the

receiving coil module and the transmitting coil module for wireless charging 103 and 203 are

paired with each other when the head band 102 is placed on the positioning block 2022, thereby

realizing wireless charging to the headphone body 10. In the present embodiment, preferably, an

upper surface of the positioning block 2022 is in an arc shape matching a shape of the head band

102. The receiving coil module for wireless charging 103 is located close to a rear cover of the

earpiece 101, and the battery is located inside the earpiece 101. Based on the above design, the

headphone body 10 is positioned on the supporting plate 201 of the headphone base by the
