Detailed Description

Embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

Headphones (earphone, also known as headphone, head-set, earpiece) may be used as an accessory to a terminal device, including but not limited to a handheld device, a car device, a wearable device, a computing device, or other processing device connected to a wireless modem, for a conversation or other audio playback scenario. The terminal devices may include cellular phones (cellularphone), smart phones (smart phones), personal Digital Assistants (PDA) computers, tablet computers, laptop computers (lap computers), car computers, smart watches (SMART WATCH), smart bracelets (smart wristband), pedometers (pedometer), and other terminal devices with talk functions. The terminal device in the embodiment of the application can also be called a terminal. Audio playback scenes include, but are not limited to, indoor scenes, outdoor scenes, in-vehicle scenes. The audio playback scenes may also include quiet scenes, noisy scenes (e.g., street, mall, airport, station, worksite, in the rain, watch games, concerts, etc.), riding scenes, outdoor windy scenes, monaural scenes, binaural scenes, and others. The earphone can be a pair of conversion units, which are used for receiving the electric signals sent by the media player or the receiver and converting the electric signals into audible sound waves by using a loudspeaker close to the ears.

Headphones can be generally classified into wired headphones (wired headphone or WIREDHEADSET) and wireless headphones (WIRELESS HEADSET). The wired earphone is provided with two earphones and a connecting wire, wherein the left earphone and the right earphone are connected through the connecting wire. The wired earphone may be inconvenient to wear and needs to be connected with the terminal device through an earphone jack, and electric quantity of the terminal device needs to be consumed in the working process. The wireless earphone can communicate with the terminal device by utilizing a wireless communication technology (such as Bluetooth technology, infrared radio frequency technology, 2.4G wireless technology, ultrasonic wave and the like), compared with a wired earphone, the wireless earphone is more convenient to use because the wireless earphone gets rid of the constraint of a physical wire rod, and is rapidly developed. Wherein, wireless headset's left earphone can be through bluetooth connection right earphone.

Bluetooth is a low-cost high-capacity short-interval wireless communication standard, the Bluetooth standard adopts microwave frequency band operation, the transmission rate can be 1 Mbyte per second, the maximum transmission interval can be 10 meters, and the maximum transmission interval can reach 100 meters after adding transmitting power. With the elimination of earphone jacks and popularization and version update of the Bluetooth technology of part of terminal equipment, various wireless Bluetooth earphones are introduced into the market, from early business type single-ear Bluetooth earphones for conversation scenes, stereo Bluetooth earphones capable of supporting music playing, and true wireless Bluetooth earphones which completely abandon wires, the functions of the wireless earphone are more and more abundant, and the application scenes are more and more.

The existing wireless earphone is usually designed as an ear-hanging type, and the ear-hanging type refers to that the earphone is mainly hung on the auricle of a human body by means of an ear-hanging part (an ear-hanging component in the application), and in order to adapt to the modeling of the auricle of the human body, the ear-hanging part is usually designed in a curve modeling mode by the modeling of the auricle of the human body. When the ear-hook part is hung on the auricle, the inner side surface of the earphone main body is clung to the outer surface of the auricle, and the earphone is fixed on the auricle by the clamping force formed between the ear-hook and the earphone main body part.

On the basis of the above, the ear-hanging earphone adopting the wireless communication technology is generally designed as an open earphone, a semi-open earphone and a closed earphone. The above classification modes are mainly distinguished according to the fact that the earphone sound outlet Kong Shifou is plugged into the auditory canal, the open earphone refers to the fact that the earphone sound outlet hole is positioned outside the external auditory canal, and the closed earphone refers to the fact that the earphone sound outlet hole is completely plugged into the external auditory canal.

The embodiment of the application provides a novel open earphone, wherein when the earphone is worn, the earphone main body part can be accommodated in the concha cavity and supported by the concha cavity so as to improve the wearing stability. Meanwhile, when the earphone is worn, the earphone main body part avoids the tragus, so that wearing comfort is improved.
