Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a speaker input device of a speaker system which is an audio reproducing device.

[0002]

[Prior art]

 In recent years, a speaker input device is required to have a speaker input device for a main speaker, a speaker input device for a sound field reproduction speaker, and a plurality of systems of input devices in order to realize sound field reproduction by an audio reproduction device. There is.

An example of the above-described conventional speaker input device will be described below with reference to the drawings.

FIG. 4 is a perspective view of a speaker input device mounted on the back surface of a conventional speaker box. FIG. 5 shows a conventional speaker input device and its mounting sectional view. In FIG. 5, reference numeral 21 is a cabinet, and a main speaker 22 and a sound field reproducing speaker 23 are attached to the cabinet 21.

Reference numeral 24 denotes a main speaker input device, which is an input system for signals of the main speaker. A rotary lever 25 and an input terminal 26 are provided, and the rotary lever 25 is incorporated in the main speaker input device 24 so that it can rotate in an arc around a rotation fulcrum 25a. The rotary lever 25 is rotated upward, the speaker cord is inserted through the insertion hole 24a, the rotary lever 25 is rotated downward, and the speaker cord is sandwiched between the rotary lever 25 and the input terminal 26 to be connected. The terminal soldering portion 26a is connected to the main speaker 22 by the main speaker wiring lead 28 connected to the printed circuit board 27 and soldered to the printed circuit board 27 on which the network circuit is mounted. Reference numeral 29 is a screw for attaching the main speaker input device 24 to the back surface of the cabinet 21.

Reference numeral 34 denotes a sound field reproduction speaker input device, which is an input system of a signal of the sound field reproduction speaker. It has the same structure as the main speaker input device 24, 31 is a rotary lever, 31a is a rotation fulcrum, 32 is an input terminal, and 34a is an insertion hole. Similar to the main speaker input device, it has a structure in which a speaker cord is inserted and inserted into the insertion hole 34a. The speaker wiring lead 33 for sound field reproduction soldered to the input terminal soldering portion 32a is connected to the speaker 23 for sound field reproduction.

[Problems to be solved by the device]

 However, since the conventional speaker input device as described above uses two of the same speaker input devices, the speaker input device for the main speaker and the network circuit mounted printed circuit board 27 which require the network circuit mounted printed circuit board 27 are required. There was a mistake in the production department that the speaker input device of the speaker for sound field reproduction that does not need to be installed was mistaken, the production cost was high, and there were many wiring mistakes by the user.

The present invention has been made in view of the above conventional problems, and an object thereof is to provide a speaker input device that is inexpensive, easy to manufacture, and has less miswiring.

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, a speaker input device of the present invention comprises a first input system in which a speaker cord is sandwiched between a rotary lever and an input terminal by a rotary lever, and a second input system including an RCA input terminal. It is configured to have one speaker input device.

[0010]

[Action]

 In order to solve the above-mentioned problems, the speaker input device of the present invention has a first input system in which a speaker cord is sandwiched between a rotary lever and an input terminal by a rotary lever, and an RCA input terminal. By providing the second input system described above in a single speaker input device, an inexpensive speaker input device can be realized with a small number of parts and a small number of steps.

【Example】

 Hereinafter, embodiments of the speaker input device of the present invention will be described in detail with reference to FIGS. 1, 2, and 3. 1 is a perspective view of a speaker input device according to an embodiment of the present invention and its mounting state, FIG. 2 is a sectional view of the speaker input device according to an embodiment of the present invention and its mounting state, and FIG. 3 is the present invention. FIG. 3 is an enlarged cross-sectional view of the speaker input device in one embodiment.

In FIG. 2, reference numeral 1 is a cabinet, and a main speaker 2 and a sound field reproducing speaker 3 are attached to the cabinet 1.

Reference numeral 4 denotes a speaker input device, which is provided with a rotary lever 5 and an input terminal 6, and rotates the rotary lever 5 upward about a rotation fulcrum 5a, inserts a speaker cord from the insertion hole 4a, and rotates the rotary lever 5. It has a structure in which it rotates downward and the speaker cord is sandwiched between the rotary lever 5 and the input terminal 6 and connected. The rotary lever 5 and the input terminal 6 form a first input system. The portion 6a is connected to the main speaker 2 by a main speaker wiring lead 8 connected to the printed circuit board 7 which is soldered to the printed circuit board 7 on which the network circuit is mounted.

Reference numeral 9 denotes an RCA input terminal, which has a structure of being integrally incorporated in the speaker input device 4 in which the first input system is formed and which forms a second input system. The input terminal soldering portion (hot) 9a and the RCA input terminal soldering portion (earth) 9b are soldered to the sound field reproducing speaker wiring lead 10 and connected to the sound field reproducing speaker 3.

[0015]

[Effect of device]

 As described above, the present invention provides a single speaker input device with the first input system in which the speaker cord is sandwiched between the rotary lever and the input terminal by the rotary lever and the second input system including the RCA input terminal. The speaker input device has the function of two, so there is no need to use two, eliminating mistakes in the production department, and reducing the number of parts and the number of parts. The speaker input device can be installed by man-hours, and there is no compatibility between the first input system and the second input system when wiring, so there is no wiring error by the user, and it is extremely It is useful.
