Then, guiding to the cord guiding groove 18, an attachment plug 5 is stored in a plug housing part 12 by allowing a terminal 11 a to be directed in a direction of internal side. When the head receiver is used for an external speaker, the terminal 11 a of attachment plug 5 is directed to an outside and is fitted in the plug housing part 12 and then the protruded terminal 11 a is inserted into a head phone jack of acoustic equipment.

Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD OF THE INVENTION The present invention relates to a speaker-cum-headphone device in which an ear-set headphone has a function as an external speaker.

[Technical background of the invention and its problems] Storage cases for storing inner-ear headphones when not in use have been known. Figure 4 shows an example of a storage case for such inner-ear headphones.
A collar part 2 is formed to guide the cord by sandwiching the winding trunk part, and a headphone storage part 3 is formed on the side surface of the collar part 2 to fit and store the headphone.
A notch 4 is formed in the flange 2 to lead out the cord near the headphone unit, and the notch 4 and the headphone unit housing 3 are connected by a cord guide groove 5.

This storage case is used only to store or transport the inner-ear headphones, and when used, the inner-ear headphones are removed from the storage case.

On the other hand, in audio equipment that uses inner-ear headphones, the fifth
As shown in the figure, a small external speaker 6 having a plug 6a connectable to a headphone jack of an audio device is also known.

However, such conventional headphone storage cases and external speakers can only function as a storage case or external speakers, respectively, and therefore, when trying to perform both with inner-ear headphones and external speakers, had the disadvantage that both had to be prepared, making it inconvenient to carry.

[Object of the Invention] The present invention has been made to solve these conventional problems, and by providing the headphone storage case with a function as a speaker baffle, it is possible to use both the headphones and the speakers. The purpose of the present invention is to provide a headphone device that functions as a speaker and is capable of exhibiting its functions.

[Summary of the Invention J In other words, the present invention provides for a storage case main body having a cord winding section, a plug storage section, and a headphone unit storage section for inner-ear headphones. The headphone unit is fitted into the opening with the front surface facing the case, and the case is provided with a baffle function for the headphone unit. It is designed to function as both a speaker and a speaker.

[Embodiments of the invention] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a rear view of one embodiment of the present invention, and FIG. 2 is a side sectional view taken along line II--II in FIG.

The speaker-cum-headphone device of this embodiment is composed of a cord reel body 2 and an inner-ear type headphone 8 attached to the cord reel body.

The cord reel main body 2 has a rectangular shape, and has a winding drum section 9 around which the cord is wound, and a pot section 11 that guides the cord 10 across the winding drum section 9. There is. Further, on the back surface of the cord reel main body 7, a plug storage part 12 into which the plug 11 of the inner-ear headphone 8 can be fitted is formed at a symmetrical position on the extension of the plug storage part 12 at a predetermined interval. Headphone storage section 14 into which the headphone unit 13 can be fitted
is formed.

Further, an opening 14a is formed on the front surface of the cord reel main body 7 at the position of the headphone storage section 14, and when a headphone unit is fitted into this opening 14a, the side plate on the front side The horn unit has a baffle function.

Furthermore, two notches 15 and 16 are formed in the collar 11, and a cord guide groove in which the cord 10 can be stored is formed between the notch 15 and the headphone accommodating part 14, and between the notch 16 and the plug accommodating part 12. 17.18 are formed. Note that the plug storage section 12 accommodates the terminal 11 of the plug 11.
When the terminal 11a of the plug 11 is turned outward for FM viewing, the terminal 11a protrudes from the collar 11 of the cord reel body, and when the terminal 11a of the plug 11 is stored with the terminal 11a facing inward, the entire plug 11 can be stored. It is formed like this.

When the speaker-cum-headphone device of the present invention is used as a storage case, each headphone unit 13 is fitted into the headphone storage portion 14, and the cord 10 continuing from the headphone unit 13 is inserted into the cord guide groove 18. The cord 10 is guided to the cutout 15 of the collar 11, guided from the cutout 15 to the winding drum 9, and wound around the outer circumference of the winding drum 9, until the cord 10 is insufficient for one winding of the winding drum 9. At this point, insert this cord 1 from the notch to the cord guide groove 18.
0 to fit the plug 12 with the terminal side facing inward. In addition, when this headphone device that also serves as a speaker is used as an external speaker, the plug 11 is inserted into the plug housing 12 with the terminal side facing outward, and the terminal 12a protrudes from the brim of the plug housing.
As shown in the front view of FIG. 3, the headphone jack 20 of the audio equipment may be inserted.

In the speaker-cum-headphone device of this embodiment, the side plate of the cord reel main body functions as a baffle, so by inserting it into the headphone jack of an audio device, it can be used as an external speaker. Furthermore, when stored in the cord reel body with the plug terminal inside, it can be used as a normal headphone storage case.

[Effects of the Invention] As explained above, the speaker-cum-headphone device of the present invention has both the function of a headphone storage case and the function of an external speaker, so it can be used as a portable device for storage, storage, or storage. Convenient for transportation.
