Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below.

Please refer to fig. 1 and fig. 2, wherein fig. 1 is a perspective assembly structure diagram of a headset according to the present invention, and fig. 2 is a perspective exploded diagram of the headset shown in fig. 1. The headset 10 is intended for use in a user's head-mounted manner. The headset 10 includes a first ear cup 11, a second ear cup 13, and a bridge 15. The first earmuff 11 and the second earmuff 13 are symmetrically arranged at two suspension ends of the head beam 15. When the user uses, wherein the head roof beam 15 butt user's top of the head, first ear muff 11, second ear muff 13 paste respectively and locate user's left ear and right ear, realize that auditory signal spreads into people's ear.

Referring to fig. 3, an exploded view of the earmuff shown in fig. 1 is shown. The first ear cup 11 includes a front shell 111, a rear shell 113, and an electroacoustic conversion unit 115. The front case 111 and the rear case 113 enclose a receiving space to receive the electroacoustic conversion unit 115. The electroacoustic conversion unit 115 generates a sound signal to be transmitted to the human ear through the front case 111.

The rear housing 113 includes a groove 1131, a light-transmitting slit 1133 and a pivot hole 1135. The groove 1131 is disposed near the rear case 113 near the side surface of the receiving space. The light-transmitting slit 1133 is in the shape of a slit and penetrates through the rear housing 113, so that the headset 10 generates a light-emitting effect when in a working state. The pivot hole 1135 is disposed on a side surface of the rear housing 113 near the end of the head beam 15, and one end of the head beam 15 penetrates through the pivot hole 1135 and extends into the accommodating space.

The second ear cup 13 is identical to the first ear cup 11, and the only difference is that the two ear cups are symmetrically arranged relative to the head beam 15. The other end of the head beam 15 passes through the pivot hole (not shown) of the second ear cup 13 and extends into the second ear cup 13.

Please refer to fig. 4, which is another angle diagram of the head beam shown in fig. 1. The head beam 15 includes a body 151, a first connection end 153, and a second connection end 155. The body 151 is in a curved elongated arc configuration. The first connection end 153 and the second connection end 155 are respectively located at two opposite ends of the body 151. The head beam 15 has a through hole passing through the first connection end 153, the body 151, and the second connection end 155 in sequence. The first earmuff 11 and the second earmuff 13 are electrically connected to each other through a wire (not shown), and the wire (not shown) penetrates through the through hole of the head beam 15, so as to prevent the wire from being exposed to the environment.

Referring to fig. 5, a side cross-sectional view of the first connecting portion and the first earmuff shown in fig. 4 is shown. The first connection end 153 includes a shaft 1531, a rubber gasket 1533, a sliding abutting stop 1535, a cover 1537 and a rotating abutting stop 1539.

The shaft body 1531 is a hollow cylinder, and the hollow structure thereof forms the through hole and penetrates the head beam 15. The rubber gasket 1533 is sleeved outside the shaft body 1531 and is correspondingly accommodated in the groove 1131. The sliding abutment stop 1535 is disposed on an outer surface of the shaft body end portion and limits the stroke of the shaft body 1531 sliding up and down along the pivot hole 1135. The cover 1537 is correspondingly disposed at the location of the groove 1131, and cooperates with the rear case 113 to form a closed cavity to accommodate the shaft 1531 therein. The rotation stop 1539 is also disposed on an outer surface of the end of the shaft body 1531, and is received in the closed cavity to limit the first earmuff 11 from rotating in a radial direction within a predetermined rotation angle.

When the first connecting end 153 is assembled with the first earmuff 11, it comprises the following steps:

step S01, providing the rubber gasket 1533 to be sleeved on the outer side of the shaft body 1531;

step S02, the shaft body 1531 penetrates through the pivot hole 1135 to the closed cavity surrounded by the cover body 1537 and the rear shell 113, so as to complete the assembly of the first connection end 153 and the first earmuff 11.

When it is necessary to extend the length of the head beam 15 or to contract the length of the head beam 15, the user applies an external force along the extending direction of the shaft body 1531, so that the first earmuff 11 can slide up and down along the extending direction of the shaft body 1531 under the action of the external force due to the friction action of the rubber gasket 1533 and the loose fit of the shaft body 1531 relative to the pivot hole 1135; when the external force is removed, the rubber gasket 1533 ensures that the two are relatively stationary due to friction. The range of the up-and-down sliding stroke of the shaft body 1531 in the closed cavity is between the upper end or the lower end of the sliding abutting-stopping member 1535 abutting against the upper end or the lower end of the groove 1131, that is, the length of the groove 1131 limits the stretching or shrinking length of the head beam 15 relative to the first earmuff 11, thereby realizing the length adjustment of the user on the headphone 10.

On the other hand, the headset 10 is divided into an open mode and a storage mode according to different operation states thereof. When the headset 10 is in the open mode, the electroacoustic conversion unit 115 correspondingly generates a light beam passing through the light-transmitting slit 1133, indicating that it is in the working state. When the headphone 10 is in the storage mode, the electroacoustic conversion unit 115 stops operating. For the user, when the user needs to switch from the opening mode to the storage mode, the first ear cup 11 is manually rotated by ninety degrees, so that the working surface of the first ear cup 11 faces outwards, and the storage is convenient. In the rotating process, the rotating abutting-against stopping piece 1539 is formed on the outer surface of the end portion of the shaft body 1531, the shaft body 1531 rotates to drive the rotating abutting-against stopping piece 1539 to rotate relative to the groove body 1131, and when the rotating abutting-against stopping piece 1539 abuts against the side wall of the groove body 1131, the rotation is stopped, so that the limited rotation of the shaft body 1531 relative to the first earmuff 11 is realized.

In summary, the shaft body 1531 slides up and down relative to the groove body 1131 and rotates within a set angle, so as to extend, contract and stretch the first connecting end 153 relative to the first earmuff 11 and rotate within a set angle.

Referring to fig. 4 again, a flexible material is adhered to the inner side surface of the main body 151, and when the headphone 10 is worn on the head of a user, the flexible material abuts against the head of the user to improve comfort.

Accordingly, the second connecting end 155 is identical to the second earmuff 13 in structure and operation, the only difference being that it is symmetrically arranged with respect to the head rail 15. When the user needs to adjust the relative position relationship between the head beam 15 and the second earmuff 13, the second earmuff 15 can extend or contract relative to the second connecting end 155 by pulling correspondingly due to the application of external force, so as to realize relative movement between the two; further, based on different operating conditions, the second earmuff is correspondingly rotated relative to the rotation angle of the head beam 15, so that the use or the storage of the second earmuff is facilitated.

Compared with the prior art, in the headphone 10 of the present invention, the two opposite ends of the head beam 15 are respectively provided with the rotation abutting stop member and the sliding abutting stop member to limit the relative sliding and rotation between the shaft body and the groove body, so as to control the relative stretching, shrinking and rotation between the head beam 15 and the cover bodies 11 and 13, so that the headphone 10 is convenient to use, adjust and store in a non-working state in different working states.
