Description

Bluetooth headset convenient to change earphone headgear

Technical Field

The utility model belongs to the technical field of earphone equipment's technique and specifically relates to a bluetooth headset convenient to change earphone headgear is related to.

Background

The earphone is a pair of conversion units which receive the electric signals sent by the media player or receiver and convert the electric signals into audible sound waves by using a loudspeaker close to the ear. The Bluetooth headset applies the Bluetooth technology to the hands-free headset, so that a user can avoid annoying wires and stumbling and can easily talk in various modes freely.

Most of the existing Bluetooth earphones are in-ear type earphones, and earphone head sleeves are arranged on the existing Bluetooth earphones. However, in order to facilitate mass production and cost control, the appearance and size of the earphone are mostly uniform and unchangeable, the ears of a human body are different from person to person, and the size, appearance and the like of the ears do not have a certain size, so that when the earphone with the uniform size is matched, a user can feel uncomfortable, and the phenomenon of being too loose or too tight occurs, and then the phenomenon that the earphone is difficult to wear or is easy to loosen is avoided.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a bluetooth headset convenient to change earphone headgear, it can be when people use, is suitable for different users' ear size, improves the rate of adaptation of product.

Detailed Description

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

Referring to fig. 1 and fig. 2, for the utility model discloses a bluetooth headset convenient to change earphone headgear, including earphone body 1, integrated into one piece has installation head 2 on earphone body 1, installs the earphone headgear 3 that silica gel made on the installation head 2.

Referring to fig. 1 and 2, the mounting head 2 is cylindrical, and a pressing ring 21 is integrally formed on an outer side wall of the mounting head 2, and the pressing ring 21 is located on a side of the mounting head 2 away from the earphone body 1. The earphone head cap 3 includes a cylindrical mounting tube 32 and a plug 31 having a hemispherical shell shape, the plug 31 has a communication hole 311, the communication hole 311 is formed in the bottom of the plug 31, one end of the mounting tube 32 is connected to the communication hole 311, and the other end of the mounting tube 32 is located inside the plug 31. The thickness of the side wall of the mounting cylinder 32 is larger than that of the plug body 31, and the inner diameter of the connecting end of the mounting cylinder 32 and the plug body 31 is smaller than that of the end of the mounting cylinder 32 far away from the plug body 31. The plug body 31 is thin, can be more easily deformed, and is more comfortable when people wear the earphone, the side wall thickness of the installation barrel 32 is thicker, the strength of the installation barrel 32 is improved, and the service life of the installation barrel 32 is prolonged. A limiting ring 33 is integrally formed on the outer side wall of the mounting cylinder 32, and the limiting ring 33 is located at one end of the mounting cylinder 32 far away from the communication hole 311. The mounting tube 32 is further sleeved with a butting ring 34, the outer side surface of the butting ring 34 is butted against the inner side surface of the plug body 31, and two ends of the butting ring 34 are butted against the inner side surface of the plug body 31 and the limit ring 33 respectively. The mounting head 2 can be inserted and fixed in the mounting cylinder 32.

Referring to fig. 1 and 2, the cross section of the extrusion ring 21 is arc-shaped, three embedded annular grooves 35 are formed on the inner side wall of the installation cylinder 32, and the cross section of the embedded annular grooves 35 is equal to the cross section of the extrusion ring 21 in size. Gaps are arranged among the three embedded annular grooves 35, and the distance between every two adjacent embedded annular grooves 35 is equal. When the extrusion ring 21 is embedded in the embedded annular groove 35, the extrusion ring 21 is not easy to slide out from the embedded annular groove 35, so that the whole earphone head sleeve 3 can be stably sleeved on the earphone body 1, and the structure is more stable. The cross section of the extrusion ring 21 is arched, so that the cross section of the extrusion ring 21 can be worn to a lower degree on the installation cylinder 32 when being pushed into the installation cylinder 32, the times of inserting the installation head 2 into the installation cylinder 32 are increased, the arched embedded annular groove 35 can be matched with the embedded ring, and the extrusion ring 21 is more stable when being embedded in the embedded annular groove 35 with the arched cross section.

When the earphone head cap 3 is installed at ordinary times, the earphone head cap 3 can be installed on the earphone body 1 by inserting the installation head 2 on the earphone body 1 into the installation tube 32. Because the inner diameters of the two ends of the mounting hole are different, when people press the plug body 31 on the earphone body 1, the closer the plug body 31 is to the earphone body 1, the smaller the distance between the end of the mounting head 2 far away from the earphone body 1 and the end of the mounting tube 32 close to the communication hole 311. Because the earphone head cap 3 is usually made of silicone, deformation can be conveniently generated, when the mounting head 2 extrudes the inner side wall of the mounting tube 32, the outer side wall of the mounting tube 32 jacks up the abutting ring 34, and the abutting ring 34 abuts against the plug body 31, so that the diameter of the plug body 31 is increased. When the ear hole of the user is larger, the mounting cylinder 32 can be inserted deeper, so that the diameter of the plug body 31 is larger, and when the ear hole of the user is smaller, the mounting cylinder 32 can be pulled out, so that the plug body 31 is contracted, and the diameter is reduced. The plug body 31 can be well suitable for different users, can be matched with ears of different sizes, and improves the utilization rate of products.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
