Description

Detachable earphone sound outlet mouth dustproof construction

Technical Field

The utility model belongs to the technical field of the earphone technique and specifically relates to indicate a detachable earphone goes out sound mouth dustproof construction.

Background

The in-ear earphone is commonly called an earplug, and is deeply loved by consumers due to portability brought by small and exquisite volume, the in-ear earphones on the market are mainly divided into two forms at present, one form is a wired earphone, the other form is a Bluetooth wireless earphone, the wired earphone has the advantages that the stereo sound effect is easier to realize, meanwhile, the tone quality of wired transmission is better than that of wireless transmission, and the Bluetooth earphone wins the further improvement of the portability of the in-ear earphones.

Present earphone generally includes the earphone casing and locates the play sound pipe of earphone casing one end, keep sealed after stuffing people's ear in order to guarantee the earphone casing, prevent that sound from revealing, generally can be equipped with the earplug on a sound pipe, through the earplug, the user wears more comfortablely, but because present earplug is hollow structure, the tip with people's ear contact is the open-ended, earwax or dirt often can fall into a sound pipe and block up a sound pipe through this opening, thereby can harm earphone tone quality, and can not dismantle cleanly all.

Later, earphones and dustproof structures thereof appear in the market, such as CN217283318U, which comprises an earphone body, wherein the earphone body is provided with a sound guide pipe which is detachably connected with an earplug; a blocking net piece is arranged on one side of the earplug far away from the sound guide tube, the blocking net piece and the earplug are integrally formed, and the blocking net piece is used for blocking secretion in an ear canal from entering the sound guide tube; the mouth of pipe department of leading note pipe is provided with one and can dismantles the dust screen structure that magnetism is connected, and the dust screen structure sets up between earplug and leading note pipe, the blocking netting piece of earplug can prevent that the secretion in the duct from getting into in the leading note pipe, wear the health to can keep earphone tone quality stable, and can dismantle magnetism the dust screen structure can promote the convenience that the user cleared up the earphone, clears up more easily to can change dust-proof component at any time, more sanitary healthy.

However, the dustproof mesh structure includes an installation groove and a detachable dustproof sheet, the installation groove is disposed at the pipe orifice of the sound guide pipe, the dustproof sheet is embedded in the groove of the installation groove, and when the dustproof sheet is disposed in the installation groove, the top of the dustproof sheet is flush with the top end surface of the installation groove. The periphery of the bottom of the mounting groove is provided with a magnetic part, when the metal frame body is close to the bottom of the mounting groove, the magnetic part is magnetically connected with the metal frame body, the magnetic part is used for fixing the position of the dustproof sheet, the middle part of the earplug is provided with a sleeve, the inner shape of the sleeve is matched with the shape of the sound guide tube, and a recess is formed at the position of the sleeve, which corresponds to the second annular bulge; when the earplug is connected with the sound guide pipe, the sleeve is in contact with the metal frame body at the position corresponding to the second annular bulge, and the metal frame body is prevented from falling off from the mounting groove.

This kind utilizes magnetic part to carry out magnetism to the dustproof sheet and inhale fixedly and correspond through the sleeve the bellied position of second annular forms sunkenly, is used for preventing the metal framework is followed drop in the mounting groove, lead to earplug itself to need to change the design, lead to the design of product to change, the injection moulding mould of product needs to be revised, and the structure of this kind of earplug is more complicated, and is higher to injection moulding's requirement, and detachable structure between this kind of earplug and the earphone body is too complicated, influences the operation and experiences and feels.

Therefore, a new technical solution is needed to solve the above problems.
