new earphones

technical field

The utility model relates to a sound output device, in particular to a novel earphone.

Background technique

Existing earphone structure comprises earplug, earphone plug, and earplug and earphone plug are connected by wire. People who like to listen to music with earphones know that when people wear earphones to listen to music, the sound of the outside world is basically inaudible, and some important information will be missed at this time.

Contents of the invention

The utility model provides a novel earphone in order to overcome the defect that the existing earphone cannot hear external sound while listening to music.

The utility model is realized by adopting the following technical scheme: a new type of earphone, including earplugs, earphone plugs, a control box with a built-in electric signal amplifier connected between the earplugs and the earphone plug, and an external sound microphone and an external sound switch are arranged on the upper surface of the control box , There is an external volume controller on one side of the control box, and an additional power supply box on the back of the control box. When the external sound switch is turned on, the external sound microphone works, and the external sound signal is converted into an electrical signal. The microphone stops working, the earphones only play music, and the purpose of free switching can be achieved by using the external sound switch.

One end of the new earphone control box is also equipped with a clip, which can facilitate the fixing of the earphone and further increase the effect of external sound conversion.

The new earphone described in the utility model converts the external sound into the audio output of the earphone by adding an external sound microphone and an amplifying circuit on the basis of the existing earphone, so that people can listen to the external sound and music at the same time, so that people do not have to worry about missing important external sounds. The sound brings great convenience to friends who like to wear headphones to listen to music.

Detailed ways

The new earphones include earplugs 1, earphone plugs 6, a control box 5 with a built-in electric signal amplifier connected between the earplugs 1 and the earphone plugs 6, the upper surface of the control box 5 is provided with an external sound microphone 2, an external sound switch 4, and a control box 5 One side is provided with an external volume controller 3, the back of the control box 5 is provided with an additional power supply box 7, and one end of the control box 5 is provided with a clip 8. The production method of the new earphone is the same as that of the existing earphone. The production of the external sound microphone and the electric signal amplifier are all existing technologies. The production method of the hearing aid can be referred to. The additional power supply uses a larger model of silver-zinc button battery. The new earphone can realize the free switching of the listening mode through the external sound switch 4. When the external sound switch 4 is turned on, the external sound and music can be listened to at the same time; when the external sound switch 4 is turned off, the earphone only plays music.
