Earphone
An earphone including a case, a case extension unit, a plate, a cover, a first speaker and a second speaker is provided. The first speaker is disposed on a supporting portion of the plate and is disposed on a first plane different from a second plane where the second speaker is located. A distance exits in the position of the first speaker and the position of the second speaker corresponding to a direction of the sound from the earphone to the user who wears the earphone. The distance variation can make the sound field have more special effects and have better frequency response in some frequency domain. The distance variation can also avoid the interference of different sound fields generated by the speakers inside the earphone, and thus improves the performance of the whole sound field.
1. An earphone, comprising:
a case;
a case extension unit extending from the case;
a plate disposed on the case extension unit and forming a space for being as a main sound field with the case;
a cover disposed on the case extension unit and located on an external side of the plate, in opposite to the space for covering the case;
a first speaker and a second speaker, wherein the first speaker is disposed on a supporting portion of the plate and the second speaker is disposed directly on the plate, wherein the supporting portion is protruding from a surface of the plate and is extended into the extension chamber of the case extension unit and the first speaker is disposed in the extension chamber of the case extension unit, wherein the first speaker is disposed on a first plane different from a second plane where the second speaker is located to form a distance in the position of the first speaker and the position of the second speaker corresponding to a direction of the sound from the earphone to the user who wears the earphone, so as to avoid interference inside the earphone, wherein the position of the first speaker is closer to an ear of the user than the second speaker.
