[Prior Art] Generally, the communicator shown above has a convenience of being transmitted to the south because its call position is not fixed. Ke County, ^ 疋口 is a call that can be called in such a diverse place. In the case where the user's location is in a noisy environment, depending on the degree of the noise, the call may be hindered. Therefore, 'in the #--ear kit type transceiver (for example, Japanese Patent Publication '', 268310) Its sound The audio and electrical signals are in the path of the medium, and an electrical or mechanical filter (restricting the filter through the sound band) for removing high frequency sounds or electrical signals that are prone to squeal is inserted in the transceiver 'from the installation The sound of the person or the noise from the outside is transmitted from the sound inlet to the microphone via the filter, and the microphone is converted into an electrical signal' and sent to the external amplifier from the connection line, but it is used at that time. The device limits the passing frequency band, so that the high-frequency signal that becomes the source of the squeal is attenuated and the squeal is removed. 2026-8663-PF; Ahddub 5 200808088 However, in the smuggling, it is wound into a cylindrical shape, so that the heart will be covered on the hood. The ventilating sound absorbing material overlaps the a person's material, and the winding of the material in the sound guiding tube makes the heart and the guiding body's axis coincide with each other, and the part is improved, thereby improving the sound of the microphone. Sexuality, but because the microphone system has only a wooden boring hole that is not known as π.. χ ^ , A ^ 夕 克 风, so when the sound is taken from the entrance to the installer, it is in the standing 睥 ^ Into the South Earrings or from outside The sound has a noise raft, and the noise is sent, and the sound with good sensitivity is sent. U is outward. The transmission and reception of P is therefore developed by the problem of a aa ^ J solution / 夬 5 彺The purpose of the basin is to provide an ear-worn microphone that stands in the microphone but that is sensitized from 9% to the noise and always transmits the sensitivity to the transceiver. The inside is bright, oh, not poor. The utility model relates to a microphone for inputting sound, which is provided with a hollow body having a size 彡^ which is suitable for an ear hole and has an open insertion portion, and ♦ a sound in the external auditory canal which is transmitted by air vibration through the insertion portion is provided in the body. Microphone: The insertion part is inserted into the ear hole and detachably mounted on the ear to make it accessible; " two-way communication, characterized in that the microphone is set to be an inner package. The opening is arranged and disposed on the body of the opening side. The inner surface of the elastic body, and on the mouth side: the front and the back side are set to have the same diameter and the same number: the sound hole 'the front sound collecting hole is formed by the sound channel formed on the elastic body and is opened 1: ' and can be collected From the open side The ear canal sound, the rear sound collection: the sound absorbing material formed by the inner surface of the body disposed on the opposite side of the opening and the closed space formed by the magazine 2〇26-8663-PF; Ahddub 6 200808088, can be collected from the opening or set The sound of the sound path formed by the intersection of the sound path and the closed space. The present invention is as described above, because the microphone is provided in an elastic body that is enclosed in the inner surface of the body that is plugged in the opening and disposed on the opening side, and has an equal diameter and an equal number of faces on the front side and the rear side toward the opening side. The sound collecting hole' front sound collecting hole communicates with the sound collecting path and the opening formed in the elastic body, and can collect the external auditory canal sound from the open side, and the rear collecting sound hole faces the sound absorbing sound from the inner surface of the body disposed on the opposite side of the opening. The material and the confined space formed by the elastic body can collect the sound from the sound path formed by the opening or the collecting track and communicating with the closed space, so that the external auditory canal sound collected by the front collecting hole is The diffracted sound from the confined space collected by the rear collecting hole cancels out, so that the sound of the external auditory canal can be collected. Therefore, when a microphone is used to collect sound in the external auditory canal, it is possible to suppress the entry of the second signal, and the externally-transmitted transceiver always transmits a sound with good sensitivity. [Embodiment] In the first to third figures, the 1st ear-mounted microphone 1 is provided with an opening having an opening 3 which is sized to fit the shackle. Lost, this M 5. The main body 5 is made of a synthetic resin and has a substantially cylindrical shape which is circular when viewed from the side. The insertion portion 2 has an opening, and has no opening, and the inside is a closed portion. The insertion portion 2 A The central portion of the side surface of the #5 is provided in a protruding shape, and is formed of an elastic material such as i-body rubber and is not any large: lj is an ear pad 6 which is joined by a fitting ampoule. The body 5 is made up of a half hole (outer ear canal) on the side of the deafness 6 and a half part 2026-8663~PF on the opposite side; Ahddub 7 200808088 5b is fitted with a ring member 7 for your use. After the outer circumference of +邛5b, the end of the pipe body 8 embedded in the electric wiring or the like described later is expanded to be integrated. As described above, the ear-worn microphone 1 is detachably attached to the ear by inserting the insertion hole into the ear hole. After installation, the plurality of sound insulating walls 6a formed on the outer circumference of the ear are bent toward the insertion side and the reverse side and are poured in, and the outer periphery and the inner wall of the external auditory canal are in contact with each other and the external body 5 will be mortified via the doorway of the insertion portion 2 The opening of the Shiyan 3 takes in the sound signal transmitted by the air vibration, that is, the microphone of the sound in the external auditory canal is placed into the inner body U. Although the inner package is shown in the figure as shown in the form of being formed in the die hole 12 and fixed, the form of the inner bag is not limited to this shape: The elastic body n is anchored to the opening 3 so as to form an inner layer on the side of the insertion portion 2 of the main body 5, and is disposed such that its outer peripheral surface and the half portion 5a are in close contact with each other. A sound collecting hole 13 is provided at a front central portion toward the opening 3 side of the microphone 1A. A hemispherical sound hole η is formed before the sound collection ^13, and a wooden sound transport 15 is formed on the second side thereof, and the front end of the sound collecting path is formed in a groove shape by the elastic body (the front end face is oriented toward the lateral direction). One end of the sub-phone 16 is connected to the opening 3. The tether is formed in parallel by the bifurcation track 16 and the sound collection 5: the soundtrack of the elastic body 11 without the hole 12, the front end opening and the minute The 曰 曰 曰 之 之 之 之 曰 曰 曰 曰 曰 曰 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 方 在 在 在 在 在 在 在 在 在 在 在A sound collecting hole 9 having a diameter equal to that of the sound collecting hole 13 is disposed at a rear portion or a slightly upper portion of the 1 inch. Further, in the body 5, the front end is in contact with the rear end of the elastic body u, and the outer peripheral surface of the rear side and the body 5 are The half portion 5b is closely connected and arranged to form the MNCS (manufactured by Ishibashi Corporation) on the inner side of the opposite side of the insertion portion 2 of the Ahddub 8 200808088. The cs2 is a MNCS (MiCr〇Network Contr〇Ued) The StructureR product name is a combination of special polymers and oils that form a structure close to human cells. The thermoplastic material has good fluidity and can be formed with precision, and is excellent in vibration resistance or chemical resistance. It is a stable material. MNCS20 series is a sound absorbing material — 丨 丨 丨 〇 〇 〇 〇 柯In one example, the same effect can be substituted. The MNCS2() forms an internal two-chamber 21 that faces and communicates with the internal space 18. The internal space 18, 21 is in addition to the stand-up, and the 17 丄 丄 ί ί ί 曰17 is a sealed space in addition to the opening 3. Further, the volume of the internal spaces 18, 21 is larger than the total volume of the microphone 1G. 22 is an opening for the electric wires for the microphone iQ to pass through. The sound collecting hole 13 is connected by the sound collecting hole 14 formed in the elastic body η, the sound collecting path 15 and the minute sound path 16 and the opening 3, and can collect sound from the ear canal outside the opening side. On the other hand, it is located behind The sound collecting hole 19, toward the inner space (closed space) 18, 2, is formed by the sound collecting channel formed on the elastic body 11, and the sound path 16 and the opening 3 are connected to each other. Part of the sound, that is The sound path 17 enters the melody of the internal space 18 _ 1 and is not absorbed by the MNCS20 temple, and the residual diffracted sound is attenuated. In the ear-worn microphone 1, the unit is placed and the resin is made of synthetic resin. The body 5 and the resonance point are different from the elastic body of the hardness r ^ ^, and become the inner layer and the inner layer, and the two layers of the sound insulation structure of the two layers are respectively in contact with each other.外 外 外 # # # # # # # # # # # # # # # # # # # # # # # # # # # # # w w w w w w w w w w w w w w w w w w w w w w w w w w 外'If it is used as a material for reflecting sound, it can be made of a metal material such as non-recording steel. "Besides the resin material = right, according to the ear-mounted microphone 1 configured as described above, it can suppress: the transmission of the microphone Ιβ and the inside of the external auditory canal, Or each structure! Vibration. That is, the noise from , θ & σ s λ, is first reflected by the e 5 of the reflective material to the outside, so that the mechanical propagation as the propagating sound of the body ": the internal intrusive solid state The MNCS20 absorbs the sound transmitted by the mechanical transmission of the above-mentioned stimulator's use of the sound absorbing material and reduces it. P, the sound system is a sound in a material, and the representative is In the case of the use of the second and the second, the viscous friction between the moon and the wood is converted into thermal energy, and the heat energy is exchanged. Therefore, the situation of the S2◦, the material Internally, since the gap is a continuous structure between the skeletons, the sound generated by the friction between the skeleton and the air is used to convert the sound energy into heat energy, and the sound energy is attenuated and sound-absorbing. The sound channel of the sound collection is "Ή, and Π, because the bomb 11 is formed by the body 11 so that the mechanical vibration is suppressed by these sound paths and does not reach the microphone 10. The function of the above embodiment will be described. At the time of transmission and reception, the ear pad 6 attached to the insertion portion 2 of the earphone 1 is inserted into the external auditory canal and is in close contact with each other, and an earplug (not shown) is inserted into the earplug hole of the external transceiver. First, it is an external sound. As this external sound, there is mechanical propagation from the external sound source and airborne noise. These noises are mainly reflected to the outside by the reflection of the body 5 of the reflective material, and secondary to 2〇26-8663~PF; Ahddub 10 200808088 The body 5 constitutes a 2-layer wall of the elastomer i丨, which stands for I ra The MNCS20 of the 4 series and the Japanese material absorbs and absorbs a lot, and is greatly attenuated. r > Mainly has a wind sound on the surface of the body 5 or the tube bean, or a friction sound that comes into contact with the surface of the body 5 or the tube body δ. The energy of these sounds is far away from 0, ώ%曰, skin, body 5 or the tube itself is a vibrating sound source, because the material of each ^ ^ 4 Α wei is itself mechanically transmitted, so the attenuation is extremely small. ..^ A, the space facing the opening 3 of the body 5 or the pipe body 8 and the 无^^ 曰 substantially non-directional work space and the internal space of the wooden hole 1 9 side 下t, ^, 21 The 18 propagation in the wooden pupils 13 and 19 becomes the sound pressure and phase contrast. The negative and negative inputs of the L-soil phase are offset. In addition, the external desire to enter the sound of the forcible, because the outer periphery of the sound insulating wall 6a of the ear pad 6 is buckled to the outside, thereby being soundproofed. The outer ear is forced to contact the inner wall and the outer ear canal is closely followed as the residual of the outer ear, and the voice of the sputum is audible from the outer ear canal with strong directionality, 9 曰 this sound is as indicated by the arrow a, by the opening 3 Through the air, the two ends of the 15th and the erect, the first ", and the 6th respectively enter the sound channel 15 spears this day. Entering the sound channel π heart ear day is set by the sound hole 14 and the sound hole 13 of the ancient wind 10 is 100% erected by the microphone. At the same time, enter the sound of the standing as shown by the arrow b, and the absorption of the s i /, the day I 1 7 is 9. % is attenuated, and the residual is about · "Door 18 21, sub-by MNCS2. ... η... The diffracted sound is as indicated by the arrow C, and is erected by the sound hole 19 of the microphone 10. Moreover, although the use enters this state Hole: The sound pressure difference between the sounds of 3 and 19 is offset by the positive and negative inputs located in the diaphragm of the microphone: 9, and about 90% of the sound signal in the outer ear of the benevolent is not offset and remains 'remaining'八^ Transceiver, because it is passed through the reading > ^ | Wang Waikou, it will not be lost. 2026-8663-PF/Ahddub 11 200808088 The mechanical propagation or the air propagation is suppressed by the internal structure of the body 5 and the laminated body of the elastic body 11 and the MNCS 20 which are the inner layer of the inner layer.

'So the sound transmitted from the microphone 10 to the external transceiver becomes noise-free: a sound with excellent sensitization. Because m does not have to worry as much as possible, it is impossible to send a sound with good sensitivity when picking up noise when collecting sounds with a microphone. In the present embodiment, the bifurcation track 16 and the sound collecting path 17 are provided as the sound path from the opening 3 to the internal spaces 18 and 21. However, in addition to this, the bifurcation sound may not be set by the opening π 3 . Road 16, and set directly = tone 17. Further, in the microphone 5 of the embodiment, the position: the sound collecting holes 13, 19, the sound collecting channels 16, 15, 14 < the arrangement position f, the shape, and the like are merely preferred examples. The form other than this is not excluded. Further, the sound structure of the two-layer wall structure of the main body 5 and the elastic body u or the hidden (10) is not limited to those illustrated, and other modified examples may be replaced by a material having the same effect, for example, as a soundproof structure. It is a matter of course that a 3-wall structure can be used.
