1. A headrest having a speaker, the headrest comprising:

a headrest frame having a rear surface to which a driving module is coupled so that the headrest frame is movable forwards, rearwards, or vertically in response to operation of the driving module, the headrest frame having a front surface formed with a mounting space recessed rearwards and a mounting hole provided in the front surface of the headrest frame;

a speaker, inserted and fastened into the mounting space surrounded by the headrest frame, provided with an output portion facing forwards and configured to output sound, the speaker having a rear side closed by the headrest frame;

a foam pad mounted on the front surface of the headrest frame so as to cover both the headrest frame and the speaker, the foam pad having formed therein a first through hole configured to output sound forwards at a position corresponding to the output portion; and

a covering configured to cover a front surface of the foam pad and forming a front exterior of the headrest,

a headrest stay configured to connect the headrest frame to a seat, and

a headrest connector having a terminal, the terminal being coupled into the headrest connector and connected to an electric wire inserted into the headrest stay, such that the electric wire is coupled to an end of the headrest stay via the terminal so as to be connectable from outside the headrest stay,

wherein the speaker is provided with a speaker connector penetrating the mounting hole of the headrest frame and extending rearwards from the headrest frame so as to allow electrical signals and power to be applied thereto.

2. The headrest according to claim 1 , wherein:

the foam pad has a front side formed with an indent indented inwards, and

the headrest further comprises a slab pad seated in the indent of the foam pad so as to be coupled to the foam pad, the slab pad having formed therein a plurality of second through holes arranged radially at a position corresponding to the first through hole, wherein each second through hole has a smaller diameter than the first through hole.

3. The headrest according to claim 2 , wherein the covering has a front side formed with cover holes, each having a smaller diameter than the second through holes and arranged in a predetermined pattern including a gradation pattern or a radial pattern.

4. The headrest according to claim 1 , wherein the mounting space is recessed further rearwards than the speaker so as to serve as a sound box of the speaker.

5. The headrest according to claim 1 , further comprising a sound absorption pad acting as a shield between the speaker and the headrest frame so as to prevent sound leakage.

6. The headrest according to claim 1 , wherein:

the output portion of the speaker is provided as a pair of output portions spaced apart in a leftward-and-rightward direction in the headrest frame, and

the first through hole is provided as a pair of first through holes so as to correspond to the pair of output portions.

7. The headrest according to claim 6 , wherein the pair of output portions provided to be spaced apart in the leftward-and-rightward direction is integrated in the speaker, and the speaker is mounted in the headrest frame in a form extending in vertical and horizontal directions.

8. The headrest according to claim 1 , wherein the speaker is mounted in a lower portion of the headrest frame and has the output portion positioned in a lower front portion of the headrest frame.

9. The headrest according to claim 1 ,

wherein the driving module interconnects the headrest frame with the headrest stay so as to move the headrest forwards, rearwards, or vertically.

10. The headrest according to claim 1 , further comprising a headrest cover coupled to a rear surface of the headrest frame so as to enclose the driving module and configured to block rearward output of sound from the speaker.
