Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention can be used for a wristwatch having functions of radio watch, television watch, pager with message, mobile communication, cordless horn, etc. For talking purposes, it relates to earphones that are small and can be dressed.

<Prior Art> Currently, there are wristwatches as electronic devices worn directly on the body, and other special hearing aids and the like.

It is considered that there are considerable reasons why wristwatches have spread as precision machines and as electronic devices or as jewelry.

First, there are bracelets, rings, earrings, and the like as accessories from ancient times, but even if they are all worn, they exert an aesthetic effect without depriving humans of freedom of action. Second, the wristwatch is for knowing the time at any time when necessary, so it is more convenient to have it at hand than other methods.

From the above points, wristwatches are considered to be a natural development from bracelets. That is, it is considered that the wristwatch can be adapted to the social life naturally as a person normally sees a bracelet and does not feel uncomfortable.
Then, in response to the electronic age, the transition from precision machines to electronic devices.

Therefore, it can be said that the remaining rings and earrings have the potential to include completely different functions. The present invention relates to the ring.

By the way, since the wristwatches have become electronic, they have become more multifunctional, and the realization of wristwatches as pagers and mobile communication devices is approaching. However, because it handles radio waves and sound waves, it must overcome noise and transmit signals.

However, the city is full of radio noise and noise. Therefore, an antenna is effective for the former and an earphone is effective for the latter, and most of them use either of them for portable devices.
The present invention relates to this earphone.

Here we give an overview of the advantages and disadvantages of earphones.

Earphones are usually made of electroacoustic transducers, cords and plugs. The electroacoustic transducer is the main body of the earphone and is also called a transmitter or a speaker. Earphones are sold separately in the current market, and standardization of plugs and the like is progressing, and they occupy a position as an accessory to the main unit.

The first reason is that the earphone is a consumable item.
Earphones are often broken.

The cord usually does not have the mechanical strength to support the fall of the main body device, and has a limited flexibility in spite of its high frequency of use, and is prone to elastic fracture. Therefore, it is necessary to reduce the inconvenience that the main body device cannot operate as a whole due to the failure of only the earphone.

The second reason is that earphones are inexpensive and can be independently distributed as accessories.

By the way, the advantage of the earphone is that the voice is transmitted only to the individual and does not disturb others. Conversely, you can overcome various urban noises and catch a clear signal.

Then there is the convenience. Its weight is light and small, and it does not bother you when wearing yourself, such as headphones.

However, it has the following drawbacks.

First, it is prone to failure as described above.

Secondly, a long cord has to be dragged, which makes it inconvenient and easy to lose even when the main body device is not used.

Third, although it has drawbacks such as poor sound quality, it has been improved in recent years. The one that achieves the electroacoustic transducer by the earphone by the electromagnetic force by combining the voice coil and the magnet has relatively good sound quality. By the way, the present invention relates to an earphone attached to a wrist watch having a function as a radio watch or the like as a main body device. The specifications required for an earphone suitable for such a wristwatch will be considered below.

First, such earphones must have a cord of at least 1 m or more.

This is because it must be electrically connected from the wrist to the ear. However, this is inconvenient.

This is because the cord is swayed every time the arm is swung, which hinders the operation. It is not uncommon for earphones to come loose from the ear canal.

Secondly, the wristwatch is convenient for carrying, but the earphone is troublesome to carry when the main body device is not used. Usually, there's no choice but to put it in your pocket.

Therefore, it is conceivable to store an earphone in a part of the accessory.

However, since the cord exceeds 1 m and requires a considerable thickness to withstand high usage frequency, the volume itself becomes a considerable amount, and it is difficult to store the cord as it is.

Therefore, in the present invention, the following ideas are changed.

<Objects of the Invention> The present invention has been made in consideration of the above circumstances, and is optimal for a wrist watch having a function such as a radio watch, can be worn, is small, is excellent in portability, and is expected to have an aesthetic effect as an accessory. It is an object to provide an earphone that can be used and a simple communication device that uses the earphone.

<Outline of the Invention> The method of using the earphone of the present invention is fundamentally different from the conventional method.

FIG. 1 is a substantive diagram illustrating the method of use. First
In the figure, 1-1 is a human hand. 1-2 is a wristwatch having functions such as a radio watch, and an antenna 1
-3 and microphone 1-4 and earphone jack 1
It has -5. The earphone of the present invention is 1-6,
It has a cord 1-7 and a plug 1-8 as its part. The plug 1-8 is a wristwatch jack 1-
5 is plugged in and electrically connected.

Therefore, as shown in FIG. 1, the earphone 1-6 of the present invention is at the position of the finger like the ring, and the wrist watch 1-2 including the microphone 1-4 is at the position of the wrist. The cord length required for the connection is about 20 cm. Therefore, the length of cords for adults and children is 33 cm or less at most, and the cord length of the commercially available earphone is 1 m or more, so that the cord length in the present invention is 1/3 or less.

Therefore, the method of using the earphone of the present invention is naturally different. For example, it corresponds to that of a public telephone handset (in a broad sense). That is, the telephone has the transmitter at the ear position and the receiver at the mouth position, and the two work together to achieve the purpose. The positional relationship is the same in the present invention.

Fortunately, the distance between the position of the human ring and the position of the wrist matches that of the ear and mouth. It is almost the same distance.
Therefore, when using the earphone of the present invention, as a general rule,
The palm of the hand is placed on the ear and the arm is raised almost vertically, and the wrist is placed on the mouth.

In FIG. 1, the earphone 1-6, the wrist watch 1-2, and the microphone 1-4 of the present invention show this state.
Of course, both the earphone of the present invention and the wristwatch must be turned halfway and turned inward.

However, such a method of use has many advantages.

First, the required code length is short so there is no inconvenience when it is long. Code is not easily tangled. Second
Moreover, since it is unlikely that the wristwatch or the ring will fall, it is not necessary to give special consideration to its strength. The code can be thin.

From the above points, it can be said that there is an advantage that the code can be stored significantly easier.

Third, because the earphones are sandwiched between your hands and ears,
There is an advantage that the hand effectively prevents external noise in a place where noise is particularly strong. The hand has acoustic resistance to the progress of sound waves.

As a method of tying the cord without rotating the ring, the finger may be bent to the second joint and faced to the palm side.

Next, FIG. 2 shows a perspective view which is a schematic view of the present invention. Second
In the figure, 2-7 is an earphone cord, 2-8 is an earphone plug, 2-9 is a metal ring, 2-10 is a transmitter, and 2-11 is a case for storing a cord. The cords are resinous.

The transmitter 2-10 has a hole 2-12 through which a voice is passed. This transmitter has a conical shape that expands outward because it has a function of hanging on the ear. However, in order to give priority to the function as a ring, a conical shape that narrows outward is preferable. This is because when you move your hand, it becomes an obstacle such as hitting something. It is for this reason that rings are generally short and smooth.

For the same reason, the corners of Case 2-11 are also rounded. The case 2-11 has a window 2-13 for storing the cord 2-7, a notch 2-14 for holding the earphone plug 2-8 with a finger, and a recess for storing the other plug 2-8. Are formed.

It is desirable that the diameter of the metal ring 2-9 can be changed according to the various thicknesses of human fingers. If the ring may be slightly oval, holes may be provided in the ring and screwed.

<Embodiment of the Invention> FIG. 3 is a sectional view of a first embodiment according to the present invention. In FIG. 3, 3-10 is a transmitter, 3-12 is a hole for passing voice, 3-11 is a case for storing the code 3-7, and a window 3-3 is for passing the code. 13 are formed.

Case 3 with a cord 3-7 whose one end is the plug 3-8
This is to wind it inside -11.

In the case, there is a cylinder 3-16 for directly winding the cord, which is mechanically connected to the transmitter 3-10. At the lower end of the cylinder 3-16, there is a gear-shaped disc 3-15, a hole 3-17 is formed immediately above it, and a cord 3-7 is passed therethrough. The other end of the cord 3-7 passes through the hole 3-17, passes through the center of the cylinder 3-16, reaches the transmitter 3-10, and is electrically connected to the voice coil of the transmitter. The coil is omitted.

The cord 3-7 is fixed inside the cylinder 3-16 with an adhesive. This is to prevent the tension on the voice coil and the like and ensure the waterproofness of the transmitter.

The cylinder 3-16 moves integrally with the transmitter 3-10 due to its mechanical strength, and rotates together with the disk 3-15 around the cylindrical protrusion 3-18 formed on the bottom of the case 3-11. . Therefore, when the transmitter 3-10 is rotated with a finger to wind up the code 3-7, the cylinder 3-16 turns together and the code is wound up on the disk 3-15.

Code 3-7 is a coaxial double wire. This is because the coaxial type is tightly packed for winding and the tangle does not occur. It is desirable that the connecting portion between the cord 3-7 and the plug 3-8 or the hole 3-17 be covered with a vinyl cylinder to prevent the cord 3-7 from being broken so that the tension is dispersed.

3-9 is a metal ring, and a metal plate 3-19 is provided on the upper end thereof.
Is brazed horizontally. The metal plate 3-19 is removably attached to the bottom of the case 3-11. Since the thickness of a finger varies from person to person, a ring 3-9
Selects the one that suits each person, and when the earphone of the present invention fails, replaces the case.

FIG. 4 shows a top view of the earphone of the present invention. In FIG. 4, 4-9 is a ring, 4-11 is a transmitter, and 4-11.
Is a case, 4-8 is a plug, and 4-7 is a cord.

The metal concentric electrode shaft of the plug 4-8 is designated 4-20. The case 4-11 has a window 4 for passing the cord 4-7 therethrough.
-13, Pseudo jack 4-2 for accommodating the plug 4-8
1. A notch 4-22 for pinching the plug 4-8 with a finger is formed.

A protrusion 4-24 for fixing the corrugated leaf spring 4-23 is formed on the bottom of the case 4-11. Reference numeral 4-15 is a gear-type disc having corrugated teeth, which meshes with a corrugated leaf spring 4-23. Therefore, as the transmitter 4-10 is rotated with a finger, the disk 4-15 rotates against the leaf spring 4-23 and the cord 4-7 is wound up. Therefore, the leaf spring 4-23 functions to prevent the transmitter 4-10 from rotating unintentionally.

In the embodiment of the present invention, the plug 4-8 is of JIS standard, but in this case, the pseudo jack 4-21 and the case 4- are used.
Since the volume of 11 becomes unnecessarily large, it is desirable to use a small plug having a shorter length.

Now, considering wearing the earphone 1-6 of the present invention as a ring on a finger, the size thereof is limited. The length of the case 4-11 cannot exceed the length of the finger joint, and if the width exceeds the thickness of the finger, it hinders the operation of the adjacent finger.

Further, as described above, unless the corners of the case etc. are round, an object will be hit when moving the hand.

Therefore, it is desirable that the outer shape of the earphone 1-6 of the present invention is as similar as possible to that of jewelry or the like. On the other hand, as a problem peculiar to the present embodiment, there is securing of waterproofness. This is because the fingers are inevitably exposed to water when washing hands. In this embodiment, the structure is such that only the main body of the transmitter is waterproof and the other parts such as the case are not waterproof. A waterproof film that allows sound but not water is effective for waterproofing the main body of the transmitter. Can be used.

The second embodiment of the present invention comprises a ring, a transmitter and a jack, and is the same as that of FIG. 4, so its surface is omitted. The structure is that there is a jack and a transmitter on the ring,
The jack and transmitter are electrically connected and there are no active parts.

Therefore, it is very compact as a whole. Nevertheless, it requires a 20 cm cord with plugs at both ends, which is inconvenient for carrying it.

However, it's far more convenient than carrying a 1m cord.

<Effects of the Invention> According to the embodiments of the present invention, there are the following unique effects.

First, the earphone can be worn by providing a completely new article that connects the earphone and the ring.

Secondly, the earphone of the present invention having a cord length of one-third or less of that of the conventional art provides an earphone most suitable for a wrist watch having a function such as a radio watch.

Third, by rotating the transmitter, the cord can be wound around the shaft connected to it, and there is no inconvenience of carrying the cord separately. However, this is not the case in the second embodiment of the present invention.

Fourth, by combining the earphone of the present invention with a wristwatch having a function such as a radio watch, a simple transceiver can be configured as a whole and new applications as described below can be developed.

Not limited to conventional radio watches, television watches, pagers, personal identification devices, etc., new applications such as pagers with messages, taxi calling devices, simple mobile communication devices or mobile phones, cordless phones, etc. can be expected.

In addition, unique designs associated with new products can be expected.
