Technical Field

The invention relates to the technical field of earphones, in particular to a ball head self-locking earphone fine-tuning structure and an earphone.

Background

Headphones and earplugs are common audio devices, and compared with earplugs, headphones are large in size, generally have two large sound generating units, and are connected together through an elastic headband, and the sound generating units are tightly attached to human ears by means of the elastic headband during use. Because of the particularity of the integrated structure of the headset, the headset is less adaptable to different head types and ear positions of various people, and the adaptability needs to be enhanced by means of an adjusting structure capable of adjusting the position of the sound generating unit.

Among the prior art and the regulation structure function that headphone adopted is the length of adjustable bandeau or the length of adjusting bandeau and sound generating unit junction, and the former can adapt to the different shapes on top of the human head, and the latter can adapt to the different positions of ear, but all can't adjust emergence unit self angle, and the influence is worn the adaptability. And because the headset adopts the surrounding type sound generation, namely the sound generating unit surrounds the auricle by using a soft structure such as sponge and the like, a sealed space is formed to conduct sound, if the angle of the generating unit is not matched, the sealed space can be incompletely sealed, and the problems of sound leakage and the like are caused.

Especially in the high-end earphone field that requires higher to tone quality and wearing travelling comfort, the regulation structure among the prior art can't satisfy user's requirement.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The implementation of the present embodiment is described in detail below with reference to specific drawings.

As shown in fig. 1 to 3, the ball head self-locking earphone fine adjustment structure 1 includes an upper assembly 11 connected to the end of the headband 2 and a lower assembly 12 connected to the sound generating unit 3. The upper end of the lower component 12 is provided with a connecting notch 124, the lower end of the upper component 11 is provided with a lug 111, and the lug 111 is inserted into the connecting notch 124 and enables the upper component 11 and the lower component 12 to be hinged with each other.

One of two opposite end surfaces of the protrusion 111 and the connection notch 124 is provided with a ball 125 for elastically abutting against the other end surface, and the other end surface is provided with a damping structure.

When needs carry out the thin fine setting to sound generating unit 3, wear the earphone at the head, the bandeau 2 that struts provides the elastic force, makes two sound generating unit 3 hug closely in two ears, rotates the angle that sound generating unit 3 was adjusted to subassembly 12 down, because the elasticity butt of bulb 125 can provide the damping during the rotation, when rotating to required angle, the position of damping structure restriction bulb 125 keeps the angle this moment then to keep the angle of fine setting back sound generating unit 3 self. When using, bulb auto-lock earphone fine setting structure 1 can be according to the head type of difference, and accurate adjustment sound producing unit 3's angle makes its ear of laminating more, has not only increased the comfort level, is convenient for form the enclosure space moreover between sound producing unit 3 and ear, avoids taking place to leak the sound.

In the present embodiment, a plurality of ball heads 125 are disposed on the end surface of the connecting notch 124, and accordingly, the damping structure is disposed on the end surface of the bump 111. In other embodiments, the opposite arrangement is also possible, and it would also be possible to arrange the ball head 125 at the end face of the projection 111, and correspondingly arrange the damping structure at the end face of the connection notch 124.

On the end face of the connection gap, a plurality of ball heads 125 are annularly distributed, so that damping and clamping positions can be guaranteed to be provided in the circular direction, the number of the ball heads 125 in the embodiment is 10, and an included angle between the adjacent ball heads 125 is 36 °.

The damping structure may be provided in a variety of ways, for example, by providing raised lines on the end surface of the bump 111, and when the ball 125 slides into the raised lines in the raised lines, the raised lines have a certain limiting capability, so that the resistance to sliding out of the ball 125 is increased, and the function of limiting the position of the ball is achieved. Specifically, the damping structure in this embodiment includes a plurality of spherical recesses 112 on the end surface of the protrusion 111, and after the ball 125 slides into the spherical recess 112, since the spherical recess 112 has a certain depth, a certain resistance needs to be overcome when the ball 125 leaves, so that the rotation angle of the upper assembly 11 and the lower assembly 12 can be limited by the cooperation of the ball 125 and the spherical recess 112, and the upper assembly 11 and the lower assembly 12 can only rotate relatively when the rotation driving force is greater than the limiting force of the spherical recess 112 on the ball 125.

The upper assembly 11 and the lower assembly 12 can be hinged in various ways, for example, a convex cylinder and a concave cylinder are used for matching, in this embodiment, a connecting shaft (not shown) is used to hinge the upper assembly 11 and the lower assembly 12, two ends of a connecting gap 124 formed at the upper end of the lower assembly 12 are correspondingly penetrated and provided with a first shaft hole 123, a convex block 111 at the lower end of the upper assembly 11 is transversely penetrated and provided with a second shaft hole 113, the connecting shaft is inserted into the first shaft hole 123 and the second shaft hole 113, and the lower assembly 12 can rotate relative to the upper assembly 11 by using the connecting shaft as a shaft.

As shown in fig. 2, the lower assembly 12 includes a base casing 121 and a front cover 122, and the upper end of the base casing 121 is provided with a connection notch 124. When the sound generating unit 3 is installed, the sound generating unit is installed on the base casing 121, and then the front cover 122 is fastened and fixed.

As shown in fig. 1, this embodiment still provides the earphone, including bandeau 2, foretell bulb auto-lock earphone fine setting structure 1 and two vocal units 3, earphone in this embodiment, its vocal unit 3 can be adjusted the relative bandeau 2's of vocal unit 3 angle by bulb auto-lock earphone fine setting structure 1, and more subtle cooperation changes the actual feeling of wearing, has not only improved and has worn the travelling comfort, has avoided taking place moreover to leak the sound scheduling problem.

Can only set up bulb auto-lock earphone fine setting structure 1 with one side of earphone in actual design, utilize the angle position of the balanced sounding unit 3 on the left and right sides of elasticity of bandeau 2 itself, can finely tune, practiced thrift the cost simultaneously. In this embodiment, the connection between each sounding unit 3 and the headband 2 is provided with a ball head self-locking earphone fine-tuning structure 1, and the two ball head self-locking earphone fine-tuning structures 1 on the two sides can be adjusted synchronously or asynchronously, so that the actual wearing feeling can be improved more finely.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
