Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a receiver device capable of transmitting and receiving with both hands freely used.

[Prior Art] As a reception device of this type, a housing for accommodating a speaker for reception and being pressed against an auricle is provided at an end of a head arm that is conventionally wrapped around a head, and an arm extending from the housing. It is known that a microphone for transmission is built in the tip of the.

In Japanese Utility Model Laid-Open No. 63-113392, an ear hanger is mounted on a housing containing a speaker for receiving, and the ear hanger is wrapped around the outer ear to hold the housing pressed against the auricle. In addition to the above, there is disclosed a transmitter / receiver device in which a microphone for transmission is built in a tip portion of an arm extended from a housing.

[Problems to be Solved by the Invention] However, since the former wears the head arm around the head, there is a problem that it tends to cause pain when used for a long time due to a feeling of pressure and fatigue. In the latter case, the ear hanger is wrapped around the outer circumference of the auricle to hold the housing against the auricle, so the ear hanger must be wrapped around the outer circumference of the auricle in a relatively tight manner. There was a problem that it was easy to fall or drop. Furthermore, both the former and the latter adopt a type in which the housing containing the speaker is pressed against the auricle, so that sound leakage occurs between the housing and the auricle, and the transmission efficiency of the signal sound deteriorates. Inevitably, there was a problem that the volume of the signal sound had to be increased.

The present invention has been made in view of the above problems, and it is possible to store and hold the housing of the receiving speaker in the auricle without using the head arm or the ear hanger without difficulty, and It is an object of the present invention to provide a receiver device that has extremely little feeling of pressure and fatigue even after being worn for a long time, has an improved signal sound transmission efficiency, and does not require an excessive increase in volume.

[Means for Solving the Problems] A receiving device according to the first aspect of the invention is a speaker housing part which has a speaker for reception and is housed and held inside the auricle in a size that fits in the auricle and the speaker. A casing having a protrusion protruding rearward of the accommodating portion and a neck portion that extends substantially at a right angle from the rear end of the protrusion and abuts near the base of the earlobe when the speaker accommodating portion is accommodated and held in the auricle, and a casing. In a lateral position of the speaker accommodating portion, and a protrusion having elasticity that contacts the skin of the auricle when the speaker accommodating portion is accommodated and held in the auricle.

In the receiver according to the second aspect of the invention, the speaker housing portion of the housing is provided with an acoustic tube projecting laterally, and the acoustic tube is provided with the above-mentioned protrusion having elasticity. is there.

[Operation] In the device of the first aspect, when the speaker housing portion of the housing is housed and held in the auricle and the neck portion is applied to the vicinity of the base of the earlobe, the housing holding function and elasticity of the auricle itself are provided. The protrusion provided has a function of stabilizing the housing state of the housing with respect to the auricle by hitting the skin surface of the auricle (stabilization status of housing state), and the housing is held at a fixed position inside the auricle without being displaced. It Moreover, since the housing is housed and held inside the auricle, the sound emitted from the speaker housed in the housing is unlikely to leak to the outside.

In addition, since the protrusion has elasticity, it does not cause any discomfort even if it is worn for a long time, and can cope with a difference in ear size. Furthermore, it can be worn on either the left or right ear.

According to the second aspect of the invention, since the projection is backed up by the acoustic tube originally provided in the housing, the above-mentioned accommodation state stabilizing action is more remarkably exhibited at the time of mounting.

[Embodiment] FIG. 1 is a schematic perspective view of a receiver A having a transmitting function according to an embodiment of the present invention, FIG. 2 is a partially cutaway front view in which an essential part is enlarged, and FIG. FIG.

In FIG. 1 and FIG. 2, reference numeral 1 denotes a housing containing a speaker (not shown) for receiving a sound, which is a flat circular speaker housing portion 11, and a protruding portion 12 and a protruding portion 12 protruding rearward of the speaker housing portion 11. It is composed of a neck portion 13 extending substantially at a right angle from the rear end, and a sound tube 11a projecting in a direction opposite to the neck portion 13 is provided on the back surface portion of the speaker housing portion 11, and a front surface portion of this sound tube 11a is provided. A protrusion 20 having elasticity is provided. The acoustic tube 11a has a space passage communicating with the speaker housing portion 11 and has a function of improving the acoustic characteristics of the speaker.
Further, the protrusion 20 has elasticity that is hard enough to prevent the protrusion 20 from being pressed against the skin, and is made of rubber or foamed resin. A cover 14 having a large number of sound holes is attached to the front opening of the speaker housing portion 11, and a mounting portion 15 sandwiched by a pair of small protrusions 15a, 15a is formed on the neck portion 13. As shown in FIG. 2, a fitting portion 18 having a fitting hole 17 having a ring groove 16 at the end of the neck portion 13
Are formed.

The housing 1 is a hard and rigid plastic molded product, and the speaker housing 11 is sized to fit into the auricle 5 as can be inferred from FIG. The neck 13 has an earlobe when it is accommodated and held in the carrier 5.
The contour shape of the boundary between the speaker housing portion 11, the protruding portion 12 and the neck portion 13 is defined so as to hit the vicinity of the base of 51, and is continuous with a smooth contour line having no angular portions.

Reference numeral 2 is an arm, which is an arm body made of a soft and lightweight plastic tube having a waist strength that allows it to stand on its own
21 and a connection port 22 provided at the base of the arm body 21, and a tip 23 with a sound hole provided at the tip of the arm body 21, and the tip of the arm body 21 is shown in FIG. As shown in FIG. 2, the connection port 22 has a small-diameter hollow protrusion 25 having a ring-shaped protrusion 24. The hollow projecting portion 25 can be inserted into and removed from the fitting hole 17 of the fitting portion 18, and when fitted, the ring-shaped convex portion 24.
Fits in the ring groove 16 of the fitting hole 17. Therefore, when the hollow protrusion 25 is fitted into the fitting hole 18 so that the ring-shaped convex portion 24 fits into the ring groove 16 of the fitting hole 17 and the arm 2 is mounted on the housing 1, the arm 2 is Axis X that crosses the housing 1
It is free to rotate around X.

A microphone (not shown) for transmission is provided at an appropriate position of the connected body of the housing 1 and the arm 2. That is, this microphone may be built in the chip 23 or the arm body 21 or the housing 1, and in the case of being built in the chip 23, the electric wire connected to the microphone is connected to the arm 2 or the housing 1. While it is installed using the internal space of
In the case of being built in the housing, the electric wire connected to the microphone is installed and guided using the internal space of the housing 1, and the internal space of the arm 2 is used as a sound collecting passage. And
The electric wire of the microphone and the electric wire connected to the speaker are drawn out from an electric wire outlet 19 provided at the back of the housing 1. Reference numeral 4 is a conducting wire including these two types of electric wires.

Reference numeral 3 denotes an ear hanger, which is formed by extending a substantially C-shaped curved hanger portion 32 that can be wound around the outer peripheral portion of the auricle 5 on the chuck portion 31 having an oval shape. A recessed groove 33 that can accommodate the conductor wire 4 is formed. The chuck portion 31 can be fitted into and removed from the mounting portion 15 of the neck portion 13 by utilizing its elasticity, and when fitted, the chuck portion 31 is elastically pressed so that the ear hanger 3 is fixed to the housing. Also, when a rotational operation force that resists the elastic clamping force of the chuck portion 31 is applied to the housing 1 or the ear hanger 3, the chuck portion 31 rotates relative to the housing 1 while being restricted in position by the small protrusions 15a, 15a. It has a structure that can be done.

With the above configuration, the speaker accommodating portion of the housing 1 as shown in FIG.
When 11 is accommodated and held in the auricle 5, the neck portion 13 comes into contact with the vicinity of the base of the earlobe, and at the same time, the projection 20 is elastically contacted with the skin of the auricle 5 to stabilize the accommodation state of the housing 1 by the auricle 5. Let That is, the speaker housing portion 11 is the pinna 5
Although it is also held by the auricle 5 by itself, the speaker housing portion 11 rotates inside the auricle 5 and is displaced due to the movement of the wearer and the weight of the arm 2 because the holding stability is insufficient. There is a concern that it may fall off from the auricle 5, but the neck 13 hits the vicinity of the base of the earlobe, and the projection 20 backed up by the acoustic tube 11a abuts the skin of the auricle 5 so that the housing 1 is housed by the auricle 5. There is no concern that such a situation will occur in order to stabilize the speaker, and the speaker accommodating portion 11 is securely held by the auricle 5. The function of stabilizing the housed state by the projection 20 is exhibited even if the projection 20 is provided at the side position of the speaker housing 11 as shown by the phantom line in FIG. 1, but if provided on the acoustic tube 11a. By the backup action of the acoustic tube 11a, the action is remarkably exhibited. In addition, the conductor wire 4 is a concave groove of the hanger portion 32.
When the hanger portion 32 of the ear hanger 3 is wrapped around the outer periphery of the auricle 5, the speaker accommodating portion 11 accommodated in the auricle 5 is held by the ear hanger 3, so that the speaker accommodating portion 11 is It is more surely held by the auricle 5. In this case, even without using the ear hanger 3, the speaker accommodating portion 11 is reliably retained by the auricle 5 by the above-described affixing action of the auricle 5 for stabilizing the housing and the protrusion 20 for stabilizing the accommodation state. It is not essential to use 3. Further, since the speaker housing portion 11 is housed and held inside the auricle 5, the sound emitted from the speaker housed in the housing 1 is less likely to leak to the outside. In addition, the neck portion 13 of the housing 1 is attached to the chuck portion 31 of the ear hanger 3.
Since the weight of the arm 2 is reduced by mounting the arm 2, it is unlikely that the housing 1 is displaced due to the weight of the arm 2, and this is due to the above-described acupuncture-holding action of the auricle 5 and the protrusion 20. This helps to more reliably exert the function of stabilizing the stored state.

Since the tip of the arm 2 is curved, rotating the arm 2 as shown by the arrow Y in FIG. 3 causes the position of the sound collecting tip 23 to move toward or away from the mouth. The position of the tip 23 can be easily adjusted to a proper position at the mouth by this. Further, the illustrated positional relationship between the housing 1 and the ear hanger 3 is for mounting on the right ear, but when mounting on the left ear, for example, from the state of FIG. 180
Just rotate it once.

The receiver described in this embodiment has a transmitting function and is not only a substitute for the conventional handset of the telephone,
It can be used as a wireless device, a language learning device, a voice input device in computer-related equipment, a receiver device for karaoke, etc., but the receiver device of the present invention is of course applicable to earphones and headphones that do not have a transmitting function. Is.

[Effect of the Invention] According to the present invention, since the housing is held by the auricle by the auricle holding effect and the elastic protrusion, the housing state is held by the auricle. There is no need to use it and there is no room for pressure and fatigue when it is wrapped around the head, and there is no pain such as ear tightening with an ear hanger, so it can be worn even if you continue to use it for a long time There is an effect that the feeling of fatigue and the pain caused by it are almost eliminated. Further, it has an advantage that it can be attached to either the left or right ear and that the position of the tip of the arm can be easily adjusted to an appropriate position simply by rotating the arm.
