DESCRIPTION JPS57109686 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the speaker according to the present invention, and FIG. 2 is a perspective view of a folded state. 1 ... battery box, 2 ... amplifier storage portion, 3a. 3b・・・スピーカ、6・・・ステレオプラグ。 − DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable speaker device, and in particular for use in combination with a speaker-only cassette player for reproduction. The cassette player dedicated to the headphone owner is limited to one or two listeners because it does not have a built-in speaker, and it was impossible for a large number of people to listen. Therefore, there is an attempt to connect a speaker device to the above cassette player and listen to a large number of people, in which case the method of connecting the cassette player and the speaker through the cord 6 is a code n at the time of carrying It becomes a wicked one, and if you want to listen again, Corda connection or α) 9b (1 /,) 2. / AX 'There was a drawback that I could not hear immediately. The purpose of this study is to provide a new mobile 11-stroke IJ speaker device that overcomes the drawbacks of the conventional speakers as described above. Hereinafter, the present invention will be described based on the illustrated embodiment. In the figure, reference numeral 1 denotes a battery box, and 2 denotes an amplifier storage portion provided on the upper surface of the battery box 1 so as to form an inverted T shape, and these constitute the casing of the present apparatus r ′ #. 3a, 3buJi'y7: (5 speakers, "i" x "" "" beakers 3a, 3b are pivotally connected to the amplifier housing 2 by hinges 4a, 4b, and as shown in FIG. It is foldable so that the amplifier storage part 2 may be swallowed by the left and right speakers 3a and 3b. Reference numeral 5 is a bush type switch provided on the front of the amplifier housing 2. When the left channel speaker 3a is folded, each switch 5 is pressed by the speaker to become OFl ′ ′, the speaker 3a Turns on automatically when you open. 6 (t stereo plug, this stereo plug 6 is inserted into the headphone jack of the cassette player C) 61 The stereo plug 6 is pivotable by pivotally attaching the support portion 7 to the battery box 1, and as shown by a solid line in FIG. 1, it projects horizontally or vertically as an imaginary 10-05-2019 1 line, or As shown in FIG. 2, it is folded into the battery box. At the time of use of this device, as shown in FIG. 1, the left and right speakers are spread on both sides as shown in FIG. 1, the stereo plug stored in the main body is caused, and the headphone jack of a commercially available cassette player is used. The plug-in false power is automatically turned on by opening the left channel speaker. Then, the output from the cassette player is amplified by the power amplifier, and the loudness circuit and the matrix circuit built in the amplifier storage unit make the stereo feeling wide. As described above, according to the present invention, a large number of people can listen to music by adding the present apparatus to the headphone II multi-use dedicated cassette player, which has conventionally had the characteristic of being enjoyed by only one or two people. , Small size of cassette player for headphone reproduction, (3) Mi) It is possible to make the most of the merit of being lightweight. In addition, since it is possible to immediately hear the connection by removing the troublesome cord connection and inserting the plug, there is an advantage that the operation is quick and speedy and easy for anyone to use. Furthermore, if the cassette player is used sideways, it may be possible that the device tt may be exposed to protrusions such as a switch when it is used in an idle state, or in such a case, the cassette player may be used upright For example, the book '4 (41 is connected to the cassette player and FSi only by the plug, and can be rotated 360 degrees around the plug so that it can escape from the projection. In addition, since the matrix circuit can be incorporated in the 1st lens housing part, it is possible to intensify the spread of the left and right sound in a fixture, so it is possible to obtain a stereo v1 sufficient for the narrow right speaker spacing of this device. You can get a feeling. As described above, this device adds a new function to the conventional headphone birth-only cassette player (4) 98, which is a SC, a great one that can increase the utility value. 10-05-2019 2
