In the current earphone structure, the sound film and the front cover form a front cavity, the sound film and the U cup form a first-stage back cavity, and the U cup and the inner cavity of the earphone case form a secondary back cavity. The speaker is the sounding unit of the earphone, and the inner cavity of the earphone casing affects the sound field of the speaker, which directly changes the sound effect felt by the ear. At present, the headphone tuning needs to roughly debug the speaker frequency response curve, and then repeatedly debug after installing the earphone to eliminate the uncertain effect of the inner cavity of the earphone shell. However, in many cases, the effect of the inner cavity on the sound field of the horn is fatal, so that the design of the entire earphone shape is rejected.
