Preferably, the method comprises the following steps: the mounting seat is of a hollow structure. The above structure is adopted to facilitate the layout of the lines.

Preferably, the method comprises the following steps: the two ends of the headrest body are bent towards the same direction and form the earphone mounting parts respectively. By adopting the structure, the distance between the sound production plane of the loudspeaker array and the human ear is closer.

Compared with the prior art, the invention has the beneficial effects that:

the automobile seat headrest with the privacy communication function provided by the invention has the advantages of novel structure, easiness in realization and ingenious design, and can adjust the loudspeaker array according to the actual position of the ear of a passenger to adjust the posture through deflection so as to aim at the ear of the passenger, accurately send the sound into the ear canal of the passenger, prevent other passengers in an automobile from hearing the communication content and realize the privacy communication.
