DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a speaker box with a take-up lead, which makes it easy to pull out and store the speaker lead and is convenient to carry.

(B) Conventional Technology A conventional speaker is configured, for example, by incorporating a speaker body inside a rectangular parallelepiped box body (not shown).

At the time of use, the speaker box is carried to a predetermined position and installed, and the speaker box and an amplifier located at a proper position are connected. That is, a lead wire is arranged between the speaker box and the amplifier, one end plug of the lead wire is inserted into the amplifier speaker jack, and the other end plug is inserted into the speaker box jack. Then, a lead plug of a microphone arranged in a proper position is inserted into a microphone jack of the amplifier.

As a result, the electric signal acoustically converted by the microphone is amplified by the amplifier, and the microphone sound is amplified by the speaker.

(C) Problems to be Solved by the Invention In the above-described conventional speaker, the speaker body is simply installed inside the rectangular parallelepiped box. For this reason, in use, after carrying it in a suitable place and installing it, a troublesome work of separately arranging the lead wire between the amplifier and the speaker box and a work of connecting each terminal are required. Further, after use, it is necessary to remove the terminals and then wind up the lead wire, which is inconvenient in use because it is troublesome to take up and store the lead wire.

This invention solves the above problems and is one operation for carrying a speaker box to a proper place. At the same time, the work of arranging and connecting the lead wires can be simultaneously executed, and the winding and storing of the leads can be easily executed after use. An object is to provide a speaker box with leads.

(D) Means and Actions for Solving the Problem In order to achieve this object, the speaker box with the winding lead of the present invention has the following configuration.

The speaker box with the winding lead is
This stand part is rotatably cantilevered, and has a speaker built therein, and a rotary drum in which the other end of a lead whose one end is connected to the speaker is wound around the outer periphery.

In a speaker box with a winding lead having such a configuration, the stand portion has, for example, a horizontal horizontal handle portion and a horizontal installation portion that are formed by bending the upper and lower end portions of the vertical portion at right angles. It is formed in a U shape. Then, a projecting shaft for supporting is provided so as to project from the center of the vertical part of the stand part, and one end side of the rotary drum is supported by this projecting shaft. A speaker is built in the other end side of the rotary drum, and the other end side (plug side) of a long lead having one end connected to the speaker is drawn out to the outside of the rotary drum and wound around the outer circumference.

Therefore, in use, the plug of the lead wound around the outer periphery of the rotary drum is inserted into the speaker jack of the amplifier. In this state, the handle portion of the speaker box (stand portion) is gripped and the speaker box (rotary drum) is carried to a predetermined position. During this transportation, one end of the winding lead (a point where the plug is inserted into the amplifier jack) serves as a stop point, and a tensile force acts on the rotating drum. As a result, the rotary drum rotates and the lead is automatically pulled out by the amount of movement of the speaker box. Therefore, the troublesome work of separately arranging the lead wire between the speaker box and the amplifier as in the related art is eliminated. After use, simply pull out the lead plug from the speaker jack of the amplifier and then rotate the rotating drum in the reverse direction.
The leads are easily wound and stored on the rotary drum.
