Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a small ear-mounted radio mounted in the ear.

[0002]

[Prior art]

 As with conventional headphone stereos, most conventional small radios have earphones with cords attached to the ears for listening, and the radio body is usually carried in a pocket or bag.

[0003]

[Problems to be solved by the invention]

 As with the prior art, the one with an earphone and a cord has the drawback that if the cord is caught on other people's clothes or belongings on a crowded train, etc. As a result, there were problems such as deformation, breakage, and breakdown of the earphone or radio. The radio itself takes up a lot of space, so it is difficult to use it when wearing clothes that do not have pockets or work clothes that are not suitable to be put in pockets, as in farming where both hands are blocked. The drawback was that the cord was obstructed during heavy work, and the storage space for small items was reduced by putting it in a pocket. Despite these problems, there is no small radio that can be easily used without any code.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned conventional circumstances, and makes the radio body very small so that it can be mounted in the ear like a hearing aid and a small timer, and provides a space for storing the radio in a pocket or the like. There is no need for this, and the incorporation of the earphones and radio makes the cord unnecessary, and provides an ear-mounted radio that can be used anywhere at any time without risk of loss.

[0005] For this purpose, the present invention has a main body of a small case composed of a pair of hollow halves, in which a radio component circuit powered by a battery is built in, and a switch for turning on / off the radio component circuit is mainly provided. And a tuning antenna and a volume knob are provided on one arm that protrudes bifurcated from the main body, and a bar antenna is mounted in the other arm.A battery cover is provided on one side of the main body, and an earphone unit is provided on the other side. The main purpose is to attach a detachable ear clip movably to an annular portion formed on the main body on the side where the earphone unit is attached.

In the present invention, a tuning dial and a volume knob may be provided on a main body as well as a switch. In this case, only an arm for mounting a bar antenna may be protruded from the main body.

[0007]

[Embodiment of the invention]

 In the embodiment shown in FIGS. 1 to 7, reference numeral 1 denotes a small case composed of a pair of hollow halves 1a and 1b, and a radio component circuit 3 is built in a main body 2 at the center. The radio configuration circuit 3 includes a detachable circular battery 5 serving as a power supply on a substrate 4 and other necessary components, and is opened and closed by turning on and off a switch 6 provided in the main body 2. A forked arm 9, 9 a protrudes from the main body 2, a tuning dial 7 and a volume knob 8 associated with the radio configuration circuit 3 are provided on one arm 9, and a bar is provided on the other arm 9 a. The antenna 10 is loaded. The distal end of the arm 9a is opened to expose the bar antenna 10 by about 1 mm.

Reference numeral 11 denotes a battery cover that covers the opening 12 at the center on one side of the main body 2. When the battery cover 11 is removed from the main body 2, the opening 12 appears so that the battery 5 can be easily replaced. An earphone unit 13 with a pad 14 is attached to the other side of the main body 2. The earphone unit 13 is securely engaged with an opening 15 formed in the main body 2 on the opposite side of the battery cover 11.

Reference numeral 17 denotes an openable / closable ear clip, which is detachably attached to the annular portion 16 formed on the main body 2. The annular portion 16 is formed on the side to which the earphone unit 13 is attached, so that the ear clip 17 is located between the case 1 and the earphone unit 13. The ear clip 17 has a semi-circular curved surface 18 formed on the upper portion fitted to the annular portion 16, and an inward projection 19 formed at the end of the curved surface 18 engages with the knurl 16 a of the annular portion 16. Therefore, the ear clip 17 can be attached to any position of the annular portion 16 and can be displaced, so that the ear clip 17 can be attached to the earlobe even if the earphone unit 13 is inserted into either the left or right ear M. If the annular portion 16 is formed slightly oblique to the main body portion 2, the earphone unit 13 can be attached with a slight inclination since the annular portion 16 is within the plan as shown in FIG. This is preferable because the angle is widened and the ends of the arms 9 and 9a are separated from the ear M. Needless to say, the means for attaching the ear clip 17 is not restricted to that shown.

In the above-described embodiment, since arms 9 and 9a protrude bifurcated from main body 2 of case 1, bar antenna 10 faces rearward of ear when earphone unit 13 is inserted into ear M. Receiving, the tuning dial 7 and the volume knob 8 are located near the ears, and the selection of the dial and the adjustment of the volume can be easily operated with a fingertip.

FIGS. 8 to 11 show another embodiment of the present invention, in which a main body 2 of a case 1 is formed in a conical shape, and a radio configuration circuit 3 is incorporated therein. The tuning dial 7 and the volume knob 8 are provided on the main body 2, and the bar antenna 10 is mounted on an arm 9 a communicating with the main body 2. In this case, the arm 9 in the above-described embodiment becomes unnecessary. The configuration is almost the same as that of the above-described embodiment except that the configuration of the case 1 and the radio configuration circuit 3 and the arrangement of the tuning dial 7 and the volume knob 8 are different, and the same reference numerals indicate the same parts.

[0012]

[Effect of the invention]

 The above-described present invention has the following specific effects. (1) Since the earphone and the radio are combined and the radio wave can be received by the bar antenna, when the radio is inserted into the ear, the user can enjoy the radio regardless of time and place, such as commuting, walking, or on-site such as agricultural work. You can listen to the program. (2) It is not necessary to store it in a pocket or bag. Even if it is stored, it is very small, so it does not take up space and does not hinder the storage of other small items. (3) Since the cord is not required, the conventional drawback that the cord comes off due to contact with other people, etc. is eliminated, and the earphone or radio does not fall or receive an impact, etc., and damage or failure is possible. Can be avoided. (4) The position of the ear clip can be changed arbitrarily, so that it can be used by anyone regardless of the size and shape of the ear, and when the ear clip is reversed, the radio can be attached to either the left or right ear, so it is always comfortable I can listen in a good state. In addition, the entire clip can be firmly fixed to the ear with the ear clip, and the entire radio can be easily removed by removing the ear clip from the earlobe. (5) The switch, tuning dial, and volume knob are provided on the case, so you can easily turn on / off the power, change the dial, and adjust the volume with your fingertip while wearing it on your ear. (6) Depending on the color and design of the case and ear clips, it can also be used as a jewelry accessory. (7) Since the whole is very small and has a simple structure, it can be provided at a low cost without any complicated manufacturing process, and can be used effectively for a long time because the battery can be replaced.
