Abstract
A headphone has a shell, a speaker received in the shell for making sound, a covering element fixed on the shell. A top of the shell is recessed to form a receiving cavity. A damping plate is received in the receiving cavity for separating the receiving cavity and the resonance cavity. The damping plate smoothes the frequency response of the sound pressure level in the resonance cavity while the speaker making sound, which adjusts the sound and achieves a better sound effect. It is convenient to change the damping plate. As the damping plates made of different materials have the different sound effects, users can change the damping plate for changing the sound effect. So, the user can enjoy different sound effects by only changing the damping plate.
Claims3
A headphone, comprising:
- a speaker for making sound;
- a shell receiving the speaker having a top thereof recessed to form a receiving cavity, a supporting plate formed at a bottom of the receiving cavity, a damping vent formed at the supporting plate, a damping plate received in the receiving cavity and supported on the supporting plate to separate the receiving cavity and the resonance cavity for smoothening the frequency response of the sound pressure level in the resonance cavity while the speaker making sound;
- and
- a covering element fixed on the shell for pressing the damping plate in the receiving cavity, the covering element having a through hole going therethrough and corresponding to the damping vent.
