It is necessary to make each component a dedicated part with a special shape and structure, which results in higher portability, but higher manufacturing costs and a relatively higher price, or otherwise There was a problem that it became a shortage of karaoke sets.

Therefore, the present invention is intended to solve the problem. Firstly, the manufacturing cost is reduced by using a commercially available stand-alone device as a constituent element, and the performance is low while the performance is high. Another object is to provide a portable voice reproduction and loudspeaker, and secondly, to realize a structure suitable as a portable karaoke set.

[Issue to solve the problem]

In order to solve the above-mentioned problems, a microphone, a sound reproducing device and a speaker are integrally housed in a case body, and a signal processing circuit for mixing and amplifying a sound signal of the microphone and a reproduction signal of the sound reproducing device and sending the mixed signal to the speaker is provided. In the portable voice reproduction and loudspeaker, the means taken by the present invention is that the case body has a storage part to which a voice reproduction device, for example, a cassette tape player or the like should be attachable and detachable, and a signal to input the reproduction signal. The section is provided. Further, the present invention provides a front case part in which a housing part is housed in the upper part and a speaker is housed in the bottom part of the case body, and a grip part connected to the rear part of the front case part and extending substantially parallel to the front case part. And is installed on the upper end side of the grip,
The microphone is provided with a structure that includes a microphone support portion that protrudes upward from a substantially upper end position of the front case portion.

According to such means, the storage section provided in the case body is
Since an audio reproducing device as an independent device can be attached, it can be used as a normal portable audio reproducing device and a loudspeaker when this is attached. The commercial products of are manufactured and sold, and the production cost and the selling price thereof are also extremely low. Therefore, by making it possible to incorporate the sound reproducing device as an independent device, it is possible to significantly reduce the manufacturing cost. Further, in this means, when the audio reproducing device is removed, the reproduction signal is not input, but it can be used as a loudspeaker based on the input signal from the microphone, and can be used only as the loudspeaker. In this case, or when a plurality of audio playback devices of the same type are previously installed in a plurality of places where there is a possibility of use, it is possible to reduce the weight of the audio playback device by not installing it so that it is easy to carry and further improve portability. You can

In this means, the case body further comprises the front case portion, the grip portion, and the microphone support portion, so that the singer can stably hold with only one hand, and the arrangement on the microphone support portion can be improved. Because of this, access to the microphone is easy and the obstruction of the field of view can be minimized.

In addition, the microphone is located farthest and rearward of the case body when viewed from the speaker installation part, that there is a large audio playback device housing between them, and the microphone is installed. The microphone supporting portion and the front case portion on which the speaker is installed are connected only by the connecting portion between the front case portion and the grip portion, and the like, so that howling is extremely unlikely to occur.

〔Example〕

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing the structure of an embodiment of a portable voice reproduction and loudspeaker according to the present invention. The case body 6 made of hard resin has a storage case 20 for storing the portable cassette tape player 7 in the upper part, a speaker 5 in the lower part, a substantially rectangular plate-shaped front case 2 installed on the front case 2, and an upper part on the front case 2. A cylindrical grip portion 3 connected by a connecting portion 6a and a lower connecting portion 6b, and a continuous shape formed at the upper end of the grip portion 3,
It is composed of a microphone support portion 4 having a microphone 1 installed at its upper end.

The storage section 20 is formed so that the portable cassette tape player 7 can be slid from the side surface side of the front case 2, and on the side surface of the front case 2 and below the storage section 20, the cassette tape player is provided. An input terminal 10 for inputting a reproduction signal of the player 7 is installed.

FIG. 2 shows a state in which the cassette tape player 7 is inserted into this device. The operation surface where the stop button 7 _s , fast forward button 7 _f , rewind button 7 _r and play button 7 _p of the cassette tape player after insertion are completely exposed, so that there is no hindrance to the operation. Has become. After mounting the cassette tape player 7, the output terminal 8 of the cassette tape player 7 and the input terminal 10 on the front case 2 are connected by a connection cord 9.

The internal structure of this embodiment is shown in FIG. Microphone 10
The input signal is input to the mixing circuit MX together with the reproduction signal of the cassette tape player 7 and then mixed, and then amplified by a predetermined amplification factor of the amplification circuit AM. This amplifier circuit
The output signal of AM is sent to the speaker 5 and converted into voice.

Here, the power supply circuit BT supplies predetermined power to the mixing circuit MX and the amplification circuit AM, but when the cassette tape player 7 does not have its own power supply, a power supply terminal is provided inside the storage unit, It is also possible to connect the cassette tape player 7 to the power supply circuit BT together with the slide insertion. Also, similarly to this, the front case 2
It is also possible to provide the input terminal 10 installed above in the storage part 20 so that the cassette tape player 7 can be connected at the same time when it is inserted.

In this embodiment, first, in the state shown in FIG.
It can function as a mere loudspeaker that expands the voice input from the microphone 1 and outputs it from the speaker. In this case, since the heavy cassette tape player 7 is not attached, the weight of the entire apparatus is reduced and the transportation becomes easier.

Next, it is needless to say that the manufacturing cost of the portion excluding the cassette tape recorder can be reduced by forming the shape of the storage portion 20 provided in the case main body 6 so as to match the shape of a commercially available portable cassette tape recorder. However, the manufacturing cost as a whole including the cassette tape recorder can be reduced. This can be understood as a matter of course nowadays, when a portable cassette tape recorder is produced and sold in a quantity that cannot be compared with a portable karaoke set.

There are several other features of this portable voice reproduction and loudspeaker. First, since the cylindrical grip portion 3 is installed, it can be easily lifted with one hand,
At this time, the upper connecting portion 6a also functions as a supporting portion that supports the weight of the case body 6. Next, since the microphone 1 is installed above the height of the upper end of the front case 2 by the microphone support 4 continuously provided from the grip 3, it is easier for the singer to access the microphone. I have to. Moreover, the obstruction area of the visual field can be minimized. In addition, since the connection cross section from the speaker 5 to the microphone 1 is narrowed down to a small area by the upper and lower connecting portions 6a and 6b, and a heavy cassette tape player 7 is installed between the two, the speaker is originally a speaker. The vibration from 5 does not easily propagate to the microphone 1 through the case body. In addition to this, the microphone 1
The speaker 5 and the speaker 5 are installed in the farthest part of the case body 6, and the microphone is located behind the output surface of the speaker, so that howling is significantly suppressed.

The cassette tape player used in this embodiment may be a recorder that also has a recording function, and may further be provided with an audio output unit (speaker) itself.
