It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

Referring to fig. 1 to 8, an embodiment of the present application provides a headrest that may be used as a support means on a seat of a vehicle such as a vehicle or an airplane to provide excellent support for a head and a neck of a passenger, the headrest including:

headrest body 1 and acoustics module 2, headrest body 1 is inside to have the cavity, is provided with two at least sound outlet 11 and two at least sound receiving hole 12 on the headrest body 1, and acoustics module 2 sets up in the cavity. The acoustic module 2 includes a speaker component 21 and a sound receiving component 22, the speaker component 21 radiates sound outwards through the sound outlet hole 11, and the sound generated by the speaker component 21 can be transmitted to the ear of the passenger through the sound outlet hole 11; the sound receiving member 22 collects sound through the sound receiving hole 12, and the sound receiving member 22 can obtain external sound from the sound receiving hole 12, for example, the sound of a user speaking can be obtained by the sound receiving member 22 through the sound receiving hole 12.

Referring to fig. 3, the speaker assembly 21 comprises a first speaker 211 and a second speaker 212, and the angle between the sound emission direction of the first speaker 211 and the sound emission direction of the second speaker 212 is in the range of 10 ° to 170 °, for example the angle may be 10 °, 20 °, 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, 90 °, 100 °, 110 °, 120 °, 130 °, 140 °, 150 °, 160 °, or 170 °.

Specifically, the sound-producing direction of the first speaker 211 and the sound-producing direction of the second speaker 212 form an included angle therebetween to provide a three-dimensional sound-producing effect for the passenger, and the included angle between the sound-producing direction of the first speaker 211 and the sound-producing direction of the second speaker 212 is controlled to improve the sound-producing effect and the directivity of the speaker assembly 21, so that the sound-producing angle of the first speaker 211 and the sound-producing angle of the second speaker 212 conform to the listening experience of human-machine functionality after being matched, and the effect of listening for the passenger is improved.

Referring to fig. 7, a minimum angle α 1 between the sound emission direction of the first speaker 211 and the sound emission direction of the second speaker 212 may be 10, and a maximum angle α 2 between the sound emission direction of the first speaker 211 and the sound emission direction of the second speaker 212 may be 170 °. When the included angle between the sound emitting direction of the first speaker 211 and the sound emitting direction of the second speaker 212 is too small, the sound emitting direction of the first speaker 211 and the sound emitting direction of the second speaker 212 directly face the back of the head of the passenger and cannot be received by the ears of the user, so that the listening loudness and the listening quality of the user are reduced; and when the included angle between the sound production direction of first speaker 211 and the sound production direction of second speaker 212 is too big, can make the sound production of first speaker 211 and the sound production of second speaker 212 keep away from the passenger, and the passenger can't acquire the effectual sound production of first speaker 211 and second speaker 212, can reduce user's hearing experience equally.

In addition, after the sound receiving assembly 22 obtains the external sound from the sound receiving hole 12, the sound of the passenger can be conveniently picked up, the voice command of the passenger can be accurately received, and then the corresponding operation can be executed, for example, the passenger can send out the command of adjusting the inclination angle of the headrest and the wrapping degree of the headrest to the sound receiving assembly 22.

The headrest that this application embodiment provided includes headrest body 1 and acoustics module 2, and headrest body 1 is inside to have a cavity, is provided with two at least sound outlet 11 and two at least sound receiving holes 12 on the headrest body 1, and acoustics module 2 sets up in the cavity. The acoustic module 2 includes a speaker component 21 and a sound receiving component 22, and the speaker component 21 can be opposite to the sound outlet 11. Loudspeaker subassembly 21 includes first speaker 211 and second speaker 212, and the contained angle scope between the sound production direction of first speaker 211 and the sound production direction of second speaker 212 is 10-170, through the contained angle adjustment of the sound production direction between first speaker 211 and the second speaker 212, not only can reduce loudspeaker subassembly 21's sound production noise, has still improved loudspeaker subassembly 21's sound production effect and directive property, has guaranteed that the sense of hearing of passenger on the headrest is experienced.

Further, the sound emission direction of the first speaker 211 and the sound emission direction of the second speaker 212 may be included at an angle ranging from 30 ° to 160 °. When the included angle of the sounding direction is too small, the sound is too concentrated; when the sound production direction contained angle is too big, sound dispersion relatively, this application in the contained angle within range, loudspeaker component 21's stereo effect is the best.

Alternatively, referring to fig. 7, the sound emission direction of the first speaker 211 and the sound emission direction of the second speaker 212 are close to each other.

Specifically, the sound emission direction of the first speaker 211 may be within an angle range of L1 as shown in fig. 7, that is, the sound emission direction of the first speaker 211 is close to the second speaker 212, and the sound emission direction of the second speaker 212 may be within an angle range of L2 as shown in fig. 7, that is, the sound emission direction of the second speaker 212 is close to the first speaker 211, so that the sound emission direction of the first speaker 211 and the sound emission direction of the second speaker 212 are close to each other. When the sound emission direction of the first speaker 211 and the sound emission direction of the second speaker 212 are converged to form a minimum included angle α 1 and a maximum included angle α 2 as shown in fig. 7, and the sound emission direction of the first speaker 211 and the sound emission direction of the second speaker 212 are between the minimum included angle α 1 and the maximum included angle α 2, on one hand, the sound emission of the first speaker 211 and the sound emission of the second speaker 212 can be matched with each other, so as to ensure the listening loudness and the listening quality of the passenger; on the other hand, the stereo sound field formed between the first speaker 211 and the second speaker 212 can be enhanced, and the stereo sound effect of the speaker assembly 21 can be ensured.
