Abstract

A waterproof type in-ear earphone is composed of a rear chamber (1), a loudspeaker (3) and a front chamber cover (2), of which the rear chamber (1) is in sealing connection with the front chamber cover (2), and the loudspeaker (3) is provided with the magnet and a diaphragm (11); a rubber cover is arranged outside the front chamber cover (2), and is characterized in that: the rear chamber (1) is a sealed type rear chamber (1); a fine mesh cover (6) is arranged on a sound guide port (5) in the front of the front chamber cover (2).

Description

The water proof type In-Ear Headphones

Technical field:

The utility model relates to a kind of earphone, particularly relates to a kind of water proof type In-Ear Headphones.

Background technology:

For guaranteeing the tonequality of earplug, cavity segment attaches penetrable sound hole to traditional earplug in the back, can not accomplish waterproof in design.And can intake in lambda line part, feelings are heavy to cause loose contact and open circuit etc.And general earplug will be accomplished waterproof effect, must be with plastic film with its loudspeaker or ante-chamber ear Encase entirely, thereby reach waterproof.But because of the former sound of loudspeaker is intercepted, so tonequality is bad.Ante-chamber lid will be with cover cover spare, or the leading note mouth of Will ante-chamber lid progressively attenuates elongatedly, just can reach waterproof effect.The ante-chamber lid is long-pending like this seems very big.

The utility model content:

It is hermetic that the purpose of this utility model provides a kind of rear chamber, is provided with the water proof type In-Ear Headphones of fine-structure mesh cover on ante-chamber lid leading note mouth; It solved between the waterproof of existing In-Ear Headphones and the tonequality can not fine coordination technical deficiency.

For realizing that the technical scheme that the present utility model purpose is taked is:

A kind of water proof type In-Ear Headphones comprises a rear chamber, loudspeaker and ante-chamber lid, and rear chamber and ante-chamber cover in the loudspeaker that are tightly connected and contain magnet, vibrating diaphragm, and the ante-chamber lid is outer to be provided with gum cover, and it is characterized in that: rear chamber is the sealed type rear chamber; On the leading note mouth of ante-chamber lid front portion, be provided with the fine-structure mesh cover.

Sealing is provided with marine glue between the lead wire outlet of described rear chamber lower end and the tone frequency channel wire.

Described magnet is rubidium magnet; Be provided with the ultra-thin copper ring sheet that closely contacts with vibrating diaphragm in the vibrating diaphragm rear surface.

The outer surface of the sound guide tube of described leading note metastomium is provided with cannelure; Gum cover is a silica gel sheath, and sealing is filled with silica gel between silica gel sheath and the cannelure.

The beneficial effects of the utility model are: still can guarantee original acoustical quality when rear chamber has water resistance, be provided with the short circuit that marine glue can prevent tone frequency channel wire between lead wire outlet and the tone frequency channel wire; Monomer horn adopts ultrathin copper ring vibrating diaphragm, even if enter ante-chamber lid or be attached on the vibrating diaphragm still can operate as normal for water; If highdensity fine-structure mesh cover effectively intercepts contacting of water and vibrating diaphragm, bring into play protective effect simultaneously; Be provided with small-bore cannelure, silica gel and silica gel sheath closely cooperate, and safety and comfort can arbitrarily be pushed, and anti-sealing enters the ear chamber.

Embodiment:

Below in conjunction with drawings and Examples the utility model is described in further detail.

As shown in Figure 1 and Figure 2, the utility model comprises rear chamber 1, loudspeaker 3 and the ante-chamber lid 2 that fits together.Rear chamber 1 is a sealed type rear chamber 1, and sealing is provided with marine glue between the lead wire outlet 4 of rear chamber 1 lower end and the tone frequency channel wire.Rear chamber 1 is tightly connected with ante-chamber lid 2, and loudspeaker 3 are fixed in both.Cover at ante-chamber on the leading note mouth 5 of 2 front portions and be provided with highdensity fine-structure mesh cover 6, fine-structure mesh cover 6 sealing plugs are in leading note mouth 5.Sound guide tube 7 outer surfaces at leading note mouth 5 rear portions are provided with cannelure 8, and are provided with silica gel sheath 9 outside the sound guide tube 7, and sealing is filled with silica gel between silica gel sheath 9 and the cannelure 8.Sound guide tube 7 is small-bore.Fine-structure mesh cover 6 is used for the absorbed portion globule, intercepts water and contacts with vibrating diaphragm 11.

The protecgulum, the bonnet that contain rubidium magnet 10 (high energy rubidium magnet 10 suction increase 30%, and low frequency power is surge), washer 14, voice coil loudspeaker voice coil 13, vibrating diaphragm 11 (the ultra-thin waterproof vibrating diaphragm 11 of 5-9u) and loudspeaker 3 in the loudspeaker 3.Be provided with the ultra-thin copper ring sheet 12 that closely contacts with vibrating diaphragm 11 in vibrating diaphragm 11 rear surfaces.The external diameter of rubidium magnet 10, voice coil loudspeaker voice coil 13 is littler than the internal diameter of copper ring sheet 12, fixes a time-out when loudspeaker 3 protecgulum bonnets, and copper ring sheet 12 is pressed between loudspeaker 3 bonnets and the vibrating diaphragm 11, even if water enters ante-chamber lid 2 or is attached on the vibrating diaphragm 11, vibrating diaphragm 11 still can operate as normal.Copper ring sheet 12 vibrates simultaneously with vibrating diaphragm 11, has guaranteed psycho-acoustical quality.
