Detailed Description

The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

As shown in fig. 1-8, the variable adaptive headphone housing 21 includes a housing 211 that fits into the concha cavity 12. The housing 211 is provided with a housing cavity 2111, and the deformation layer 212 is arranged in the housing cavity 2111. The deformation layer 212 is attached to the inside of the housing 211, the deformation layer 212 is used for supporting the housing 211, and the deformation layer 212 can deform along with the deformation of the housing 211. The deformation layer 212 is made of a deformable soft material.

The outer wall of the housing 211 is formed with at least one adjustment slot 2112. Therefore, during specific use, the adjusting groove 2112 is positioned on one surface of the shell 211, which is attached to the skin of the human ear 1, so that the shell 211 can be pressed into different shapes by fingers more easily, and the adjusting groove 2112 plays a role in ventilation after being worn, thereby improving comfort.

The adjustment groove 2112 includes a first adjustment groove 2112a and a second adjustment groove 2112b, the first adjustment groove 2112a is opened in the radial direction of the outer periphery of the housing 211, the second adjustment groove 2112b is opened in the height direction of the housing 211, and the second adjustment groove 2112b is communicated with the first adjustment groove 2112 a. The length of the first adjustment groove 2112a of the present embodiment may be designed according to actual requirements, for example, the length of the first adjustment groove 2112a is half of the circumference of the outer circumference of the housing 211. The second adjustment slot 2112b is perpendicular to the first adjustment slot 2112a, and may be in various forms such as a T-shape or a cross-shape. Thus, the adjustment grooves 2112 are provided in two, facilitating the tension adjustment of the housing 211 in two directions.

The adjustment groove 2112 is circular arc-shaped. Thus, the arcuate adjustment slot 2112 facilitates stretching and repositioning, facilitating easy stretching of the housing 211 during collapse.

A sound outlet 2113 is formed at one end of the housing 211, and the sound outlet 2113 is matched with the ear canal opening 11. Thus, the sound outlet 2113 facilitates the entry of sound emitted from a sound output element such as a speaker into the human ear 1.

The housing 211 is an elastic housing 211. Therefore, the shell 211 of the invention is made of hard or soft materials such as silica gel which can contact with the skin of the human body, and the shell 211 made of silica gel materials is soft and easy to be attached to the inner wall of the auditory canal.

The deformation layer 212 of the present invention is made of a deformable hard or soft material for supporting and fixing the housing 211 so that the housing 211 maintains a desired form. The deformation layer 212 may be a wire mesh. Therefore, the wire mesh can support the housing 211, and can also deform in accordance with the deformation of the housing 211, so that the overall shape of the earphone shell 21 matches the shape of the ear canal of the user. The deformation layer 212 is shaped by external force such as being crushed or compressed, and can continue to maintain the deformed shape.

The invention provides an earphone shell 21 with a brand new structure, when in specific use, various parts such as a loudspeaker, a chip, a Bluetooth module or a battery and the like are installed in the earphone shell 21 according to selected requirements, then the earphone shell 21 is lightly placed in the position of the concha cavity 12 of a human ear 1, the earphone shell 21 is kneaded by fingers to be matched with the shape of the concha cavity 12 of a user, meanwhile, a sound outlet 2113 is ensured to be aligned with the position of an external ear canal orifice 11 behind an tragus, the whole earphone is not required to be inserted into an ear canal, and sound can be well transmitted to the human ear 1.

The earphone shell 21 of the invention can be adjusted to be very close to the shape of the concha cavity 12 of the human ear 1, and can be worn firmly. The earphone has the advantages that the earphone does not need to be inserted into an auditory canal, meanwhile, the ventilation function is achieved, foreign body feeling and stuffy feeling generated when the earphone is worn can be effectively reduced, and the earphone is worn for a long time. Moreover, the earphone shell 21 is placed in the concha cavity 12, which does not cause obvious sound energy loss, and can well maintain the tone quality of the output sound signal, thereby providing better listening experience for users.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
