Description

[Detailed description of the invention] (Industrial application field) This invention is a device that is equipped with a speaker that mixes and amplifies musical sounds played from a recording tape and singing voices input from a microphone, and outputs the amplified sound from a speaker. The present invention relates to a tape playing device.

(Prior Art) Conventionally, this type of tape performance device has a speaker placed at the bottom of the front panel of a box-shaped device case, a microphone connected to the top, and a device for operating the tape player or built-in amplifier. There was one where the control panel was arranged.

Furthermore, record players have been known in which an operating section and the like are provided on the back of the case, which is different from the speaker mounting surface (front) (see, for example, Japanese Utility Model Publication No. 5331/1983).

(Problem to be solved by the invention) However, in the former conventional example, when a person holds the microphone in one hand and sings while operating the operating parts of the control panel with the other hand,
There have been problems in that the microphone is close to the speaker, which tends to cause howling, and that it is difficult to operate it from the side of the tape playing device in order not to interfere with the emission of sound waves from the speaker.

In addition, in the latter conventional example, there is usually only one loudspeaker volume adjuster per system, which is difficult for those who are unfamiliar with the operation, and it is difficult to use depending on the usage situation. It was also not possible to preset the amount of volume.

Therefore, this invention was made in view of the above-mentioned conventional problems, and its purpose is to provide a tape playing device that is less likely to cause howling and that allows the effectiveness of volume adjustment to be preset. .

(Means for solving the problem) The gist of this invention to achieve the above purpose is as follows:
A speaker is attached to the front panel of the box-shaped case, an amplifier is built in to drive the speaker, and an operation panel is provided on the side panel.A tape player and microphone input jack are attached to this operation panel, and the tape player signal and microphone are attached to the operation panel. Install a normal volume that adjusts the volume of each signal, connect a priority volume with a lower resistance value in parallel to this normal volume, and place this priority volume on the back panel or side panel opposite to the operation panel. The invention consists in a tape playing device made up of:

(Function) In this manner, by providing the operation panel on a surface different from the speaker mounting surface, the distance between the microphone and the speaker is maintained large, making it difficult for howling to occur. In addition, if you connect a priority volume with a low resistance value in parallel with a normal volume that adjusts the amplification volume of the microphone signal,
Since the working range of the normal volume is preset by the priority volume, it can be adjusted to suit the usage conditions, for example, so that howling is less likely to occur.

(Example) The configuration will be explained based on the example shown in the drawings.

FIG. 1 is a perspective view of a tape playing device. A speaker 2 is attached to the lower part of a front panel 1 constituting a box-shaped case, and the front surface of the speaker 2 is covered with a protective net 3 made of punched metal or the like.

A microphone (not shown) is installed on the top of the right side plate 4.
Input jack for connection 5, cassette type tape player 6, cartridge type tape player 7, microphone volume 8, tape player volume 9, echo adjuster 10, volume indicator 11,
An operation panel 13 to which tape player operation buttons 12 and the like are attached is sunk to such an extent that the tips of these attachment parts 5 to 12 do not protrude from the surface of the side plate 4.

Furthermore, the cartridge-type tape player 7 has an insertion opening for the cartridge 1 inserted here.
4 is provided at a position sunk below the operation panel 13 so that the rear end thereof does not protrude from the surface of the side plate 4.

In addition, as shown in FIG. 2, the front plate 1, the right side plate 4, and the back plate, left side plate, or top plate 15 other than the bottom plate are connected and operated in parallel with the normally used normal volumes 8 and 9. . For example, priority volumes 16 and 17 configured to operate preferentially with a lower resistance value than the opening/closing lid 18
It is provided in a recess 19 inside.

FIG. 3 is a connection diagram of one system of the tape player volume 9 and this priority volume 17,
A volume 9,1 is connected between the signal source 20 and the amplifier 21.
7 are connected in parallel.

Incidentally, it is preferable that the priority volumes 16 and 17 are not provided on the top plate 15 when a plurality of tape playing devices are stacked and used.

Constructed as described above, all necessary operations of the tape playing device are performed via the operation panel 13 provided on the right side panel 4, and sound is emitted from the speaker 2 on the front panel 1.

Therefore, even if you hold a microphone (not shown) connected to the input jack 5 with a connection cord in one hand and operate the tape players 7, 8 or the volumes 8, 9 with the other hand, the speaker 2 will not be heard. The microphone (not shown) is not close to the front, so
Howling is less likely to occur, and various operations can be easily performed from the side via the operation panel 13 without interfering with the emission of sound waves to the front of the speaker 2.

Further, since the tips of the parts attached to the operation panel 13 are sunk so as not to protrude from the surface of the right side plate 4, the tape playing device will not break even if it falls over while in use.

If you operate the priority volumes 16 and 17 instead of using the operation panel 13, the volume will be adjusted independently depending on the number of audience members and the annoyance of the surroundings, and the adjustment position of the priority volumes 16 and 17 will adjust the volume independently. Then, the effectiveness of normal volumes 8 and 9 is set in advance.

(Effects of the invention) As described above, according to this invention, by performing side operations, necessary operations can be easily performed without interfering with sound wave radiation from the front speaker, and the microphone and speaker can be easily operated. Not only can it suppress howling due to the proximity of This provides an excellent effect in that it can be preset to a range in which howling does not occur.
