Problems solved by technology

Because the size of the ferrite core coil that meets NFMI requirements (5.5mm*2.0mm*2.0mm) is large, many TWS earphone products cannot achieve NFMI communication, or the communication effect is caused by insufficient clearance to meet the layout and wiring rules. not good

Embodiment Construction

[0054] The technical solution in this application will be described below with reference to the accompanying drawings.

[0055] Such as figure 1 Shown is a schematic diagram of a communication system 100 involved in the earphone in the embodiment of the present application. Such as figure 1 As shown, the communication system 100 may include communication between two headsets, such as figure 1 The communication between the earphone 110 and the earphone 120 is shown; the communication system 100 may also include the communication between the earphone and the terminal device, such as figure 1 Shown is the communication between the headset 110 and the terminal device 130 , or the communication between the headset 120 and the terminal device 130 . Wherein, the communication between the earphone and the earphone, or between the earphone and the terminal device mainly completes the audio signal forwarding through BT or NFMI.

[0056] Wherein, the terminal device may include a han...

Abstract

The invention provides an earphone, and the earphone comprises a battery which is disposed in an ear handle of the earphone, and forms a cylindrical body; an antenna which is electrically connected with the battery and used for transmitting or receiving signals by using power provided by the battery, wherein the antenna comprises a flexible printed circuit (FPC) coil, a radiator serving as the antenna and arranged on the side surface of the battery, the winding axis of the FPC coil is perpendicular to the height direction of the battery, and after the side surface of the battery is unfolded, the FPC coil is kept in a state of winding the coil and is flatly laid on a plane formed by unfolding the side surface. Therefore, the headphone is ensured to have enough clearance, the requirements oflayout and wiring in the headphone can be met, the communication effect of the headphone is improved, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of electronic equipment, and more specifically, to an earphone. Background technique [0002] True wireless stereo (TWS) earphones completely abandon the way of wire connection. There are three types of existing TWS earphones to establish wireless connections: dual transmission scheme, monitoring scheme, and forwarding scheme. In existing TWS earphone products, audio signals are forwarded mainly through Bluetooth (BT) or near field magnetic induction (NFMI) between the left earphone and the right earphone. Because the BT forwarding method has the disadvantages of large head-through loss and large environmental interference, the NFMI forwarding audio signal has gradually become the mainstream technology due to its advantages of low power consumption, low absorption rate, and anti-interference. Because the size of the ferrite core coil that meets NFMI requirements (5.5mm*2.0mm*2.0mm) is large, many TWS earpho...
