Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to a multifunctional head-mounted earphone. Background Art

[0002] Headphones are sound-transmitting devices that convert electrical signals from a sound source into audible sound through the principle of electroacoustic conversion. Based on how they are worn, they are primarily categorized as earbuds, earhook types, in-ear types, and headphones. Earbuds and in-ear headphones can easily cause discomfort to the user's ears, while earhook types are not suitable for users with eye problems. Headphones, on the other hand, have a wide range of applicability. Most users have two main requirements for headphones: 1. Because the distance from each user's ear to the top of the head varies, the speaker arm needs to be extendable to meet each user's wearing comfort needs. 2. Ergonomically, the ear is at a certain angle relative to the head; in order for headphones to fit the user's ear, the speaker portion needs to be able to swing a certain amount. Existing headphones can meet both the first and second requirements, but few can meet both requirements simultaneously.

[0003] Therefore, the applicant believes that it is necessary to provide a headset that can simultaneously meet the first and second requirements mentioned above. Utility Model Content

[0004] The main purpose of the present invention is to provide a multifunctional headset, aiming to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention proposes a multifunctional headset, comprising an earband and speakers arranged at both ends of the earband, wherein the end of the earband can be pivotally mounted with a connecting arm for connecting to the speaker, and the connecting arm can drive the speaker to swing relative to the earband, and the housing of the speaker is provided with a slot for the connecting arm to be inserted, and the slot has teeth on opposite sides extending along the length direction of the connecting arm, and the free end of the connecting arm is provided with a pair of first elastic parts with teeth, and the two first elastic parts are respectively engaged with the teeth on both sides through the teeth, and when the connecting arm moves in the direction of insertion into or withdrawal from the slot, the first elastic part can be forced to be locally deformed by the guiding cooperation of the teeth and the teeth to withdraw from the teeth.

[0006] Preferably, the connecting arm is made of plastic or metal.

[0007] Preferably, the first elastic part is made of plastic or metal.

[0008] Preferably, the slot is directly formed with the tooth groove or the slot is provided with a rack having the tooth groove.

[0009] Preferably, the rack is fixed in the slot by glue, screw locking or a snap-fit ​​structure.

[0010] Preferably, a pivot joint is provided at one end of the connecting arm away from the speaker, and a pivot groove suitable for the pivot joint is provided at the end of the ear band, a pin is provided in the pivot groove, and the pivot joint is pivotally sleeved on the pin to achieve pivotal cooperation between the connecting arm and the ear band.

[0011] Preferably, the side wall of the pivot joint is provided with a recess, and a second elastic part with a protrusion is provided at a position corresponding to the groove of the pivot groove. The protrusion is adapted to the recess, and when the connecting arm swings, the recess is driven to contact the protrusion and forces the second elastic part to deform locally so that the protrusion exits the recess.

[0012] Preferably, the surface wall of the protrusion is a curved surface.

[0013] Preferably, a relief hole is provided at a position of the pivotal slot corresponding to the second elastic portion, for evading deformation of the second elastic portion.

The connecting arm can be fixed in the slot by engaging the tooth portion and the tooth groove. When the connecting arm moves in the direction of inserting into or withdrawing from the slot, the first elastic part can be forced to deform through the cooperation of the tooth groove and the tooth portion, so that the tooth portion withdraws from the tooth groove. Compared with the traditional one, the utility model can not only adjust the position of the speaker to the top of the head, but also swing the speaker within a certain range. The overall structure is simple, and effectively meets the user's wearing comfort needs. BRIEF DESCRIPTION OF THE DRAWINGS
