Description

Earhole formula ear microphone

The utility model relates to electric type, particularly a kind of earhole formula ear microphone.

As everyone knows, as shown in Figure 1, general ear microphone structure includes a head hoop (1), one side hangers machine (10), and connect an electric wire (11) and a connecting rod (12) by the earphone place, establish a sound wave pick-up (13) and coat a sponges cover (14) at the terminal knot of connecting rod again and form in the pick-up appearance, this ear microphone group is because the close user's mouth of sound wave pick-up (13), and it is terminal outwardly to hang on connecting rod (12), therefore produce moment loading and must establish a head hoop (1) and stride and be buckled in the user crown, could effectively support pick-up (13) location outstanding due to user's face place, moreover connecting rod (12) is the curved body of rigidity, connecting earphone (10) locates to be provided with the joint, could adjust the outstanding allocation of terminal pick-up (13), therefore cause the cost height, part is many, the large heavy shortcoming of body, this is first shortcoming; Second shortcoming is electronics implements for pick-up (13), because near the mouth pickup, therefore being subject to the human body saliva is flying and is making moist, damage easily, though having coating sponges cover (14) to intercept saliva directly enters, again because of sponges cover (14) has water absorption, and pick-up (13) is being coated, more allowing pick-up (13) be difficult to drying; The 3rd shortcoming is, though pick-up (13) is coated with sponges cover (14), being sterilized keeps health, and the bacterium that grows in pick-up structure slit still exists, and causes and can't effectively clean.

The purpose of this utility model is exactly the shortcoming that exists at above-mentioned ear microphone structure commonly used and a kind of earhole formula ear microphone is provided, by one can simple and easy winding disposable type lightweight conduit overcome the shortcoming of above-mentioned general ear microphone structure.

The technical solution of the utility model:

The utility model mainly is made up of an earphone body, built-in sound wave pick-up, a sound wave conduit, by one can simple and easy winding disposable type lightweight sound wave conduit, the indirect conducting to of the sound wave that source of sound sent is built in the set pick-up of portion in the earphone body, make it accept sound wave in mode at interval, this conduit is flexual, the user can arbitrarily adjust angle and position, and different big or small shape of face persons use and left and right sides ear is replaceable selects for use to adapt to.

Describe structure of the present utility model and embodiment in detail below in conjunction with accompanying drawing:

Fig. 1 is the three-dimensional appearance schematic diagram of ear microphone commonly used.

Fig. 2 looks schematic diagram for master of the present utility model.

Fig. 3 is an enforcement illustration of the present utility model.

Fig. 4 is an another way structural representation of the present utility model.

(1) be that head hoop, (10) are that sponges cover, (2) for earphone body, (21) for loud speaker, (22) for foam-rubber cushion, (3) for pick-up, (30) be tusk tenon, (301) for pickup face, (31) for hollow pipeline, (32) for gilled rings, (4) for sound wave conduit, (40) be port, (5) for electric wire, (6) for earhole, (7) be mouth for connecting rod, (13) for pick-up, (14) for electric wire, (12) for earphone, (11).

As shown in Figure 2, the utility model is mainly by earphone body (2), one built-in sound wave pick-up (3), one sound wave conduit (4) is formed, earphone body (2) lining portion is provided with a loud speaker (21) so that the sound to be provided, this place's appearance cover is covered with a foam-rubber cushion (22), earphone body (2) below externally is convexly equipped with a tusk tenon (30) with hollow pipeline (31), being provided with electric wire (5) under the earphone body (2) links with loud speaker (21), sound wave pick-up (3) is located in the middle part of earphone body (2), sound wave pick-up (3) is provided with pickup face (301), sound wave conduit (4) court of a feudal ruler is located on the set tusk tenon (30) of earphone body (2), sound wave conduit (4) is that the plastic tube body of a lightweight is also bent, its internal diameter just can closely cooperate and be inserted in the external diameter of tusk tenon (30), an other port (40) is as the receiving mouth of including source of sound in, tusk tenon (30) radially convexes with ring-type gilled rings (32) at its outer round surface, so that sound wave conduit (4) is inserted in smoothly.

Accompanying drawings embodiment of the present utility model.

As accompanying drawing 2 to shown in the accompanying drawing 4, earphone body (2) below is convexly equipped with a tusk tenon (30) with hollow pipeline (31) outwardly, this hollow pipeline (31) conducting external sound source, directly invest the pickup face (301) of sound wave pick-up (3), allow it receive sound wave conversion signal and be transferred to sound appliances by electric wire (5), identical, the electric power of this loud speaker (21) is with being transmitted by the different circuits in the electric wire (5), one port of sound wave conduit (4) is inserted on the external diameter of tusk tenon (30), it is fused, other port (40) is as the receiving mouth of including source of sound in, can be near user's mouth (7), because sound wave conduit (4) is a plastic tube body and bent, so when dismounting conduit (4), as long as free-handly pinch body with finger and pull out, when assembling, grip body with finger, again with its socket port to being positioned at tusk tenon (30) port outer rim, with suitable strength port is inserted in and finishes assembling, because of sound wave conduit (4) bent, so can arbitrarily adjust angle according to the size of user's shape of face, the conduit (4) that the user can more renew at any time after sound wave conduit (4) dirt is dirty reaches the requirement of health; (as shown in Figure 3) the utility model in use, earphone body (2) is gone up set loud speaker (21) part caulked goes in user's earhole (6), and the sound wave conduit (4) that promptly hangs down and pick out electric wire (5) and import sound wave in earphone body (2) below, because above-mentioned each element center of gravity concentrates on the earphone body (2), make for light material because of conduit (4) again, therefore integral body can effectively be immobilizated in the earhole (6), dawn keeps conduit (4) can not be offset, and its terminal port (40) that imports source of sound can be hanged closely in user's mouth (7); (as shown in Figure 4) tusk tenon (30) can be located at the position of hanging down of earphone body (2), sound wave conduit (4) but turn in the external diameter of tusk tenon (30) and turn to, conduit (4) can bend and make its port (40) that imports source of sound provide work inertia to need or adapt to the difference that peripheral equipment is provided with near user's mouth (7), adjust conduit (4) through rotation and rotate 180 ° with respect to tusk tenon (30), can change direction, provide left and right sides ear to exchange and use.

The utility model structural design is simple, can reach the requirement of health aspect.
