Description

Novel microphone horn for earphone

Technical Field

The utility model relates to an earphone technical field, concretely relates to a novel microphone loudspeaker reaches for earphone.

Background

Earphones (ears; heads-sets; ears) are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers near the ears.

The existing earphone is mostly used for mobile phones, and most of the existing earphones have the functions of answering communication calls, answering voice calls, answering video calls and the like. And the earphone with the listening function is internally provided with a corresponding microphone and a corresponding loudspeaker. The main function of the loudspeaker is to convert electrical signals into sound, and the loudspeaker is a main device in various earphones at present. The horn will be placed closest to the ear opening or in the ear canal through which sound is transmitted into the ear. Meanwhile, the existing earphones are internally provided with a microphone in the structure and used for receiving voice signals. The speech signal is converted into an electrical signal.

In the general design, a wire control box is arranged on an earphone wire of the wired hands-free earphone, a microphone is placed in the wire control box, and the wire control box is close to the mouth of a person and used for receiving voice. The position of the microphone is basically consistent with that of the wired hands-free earphone. The bluetooth headset may have a microphone disposed in the headset body, and the microphone may be directed to the mouth as much as possible to receive voice.

Although the existing earphones can be used for receiving voice so as to realize telephone answering, the following disadvantages exist:

1. the position of the microphone is not fixed, the voice receiving effect is influenced by the distance, and particularly, the voice sound pressure of a real wireless Bluetooth headset is small;

2. the microphone is in an open environment, and can receive external noise while receiving voice, so that the phenomenon of unclear listening can occur. Although there is an ENC voice noise reduction algorithm in a bluetooth headset, the external noise interference problem cannot be fundamentally solved. The real wireless Bluetooth earphone is difficult to distinguish between external noise and voice due to the fact that the distance from the mouth is far. The conversation voice is unclear, the noise is large, and the Bluetooth voice call is a pain point of the true wireless Bluetooth.

Therefore, the novel microphone horn for the earphone is clear in conversation voice, low in noise and small in influence of external noise, and needs to be explored urgently.
