Abstract

A loudspeaker interconnect terminal for selectively coupling a plurality of loudspeaker drivers to a monophonic source and a stereophonic source. The terminal includes a body defined by a first side and a second side, and first and second sets of input terminals disposed on a respective one of the first and second sides. The terminal also includes an electrical switch with an actuator having a first position and a second position. The first set of input terminals are connected to the corresponding one of the second set of input terminals and a switch cover coupled to the actuator conceals at least a part of the first set of input terminals with the actuator in the first position.

Claims

1. A loudspeaker interconnect terminal for selectively coupling a plurality of loudspeaker drivers to a monophonic source and a stereophonic source, the interconnect terminal comprising:

a terminal body defined by a first side and an opposed second side;

first and second sets of input terminals disposed on a respective one of the first and second sides of the terminal body;

an electrical switch including an actuator having a first position and a second position, the first set of input terminals being connected to the corresponding one of the second set of input terminals with the actuator in the first position, and the first set of input terminals being disconnected from the corresponding one of the second set of input terminals with the actuator in the second position; and

a switch cover coupled to the actuator, the switch cover concealing at least a part of the first set of input terminals with the actuator in the first position, thereby restricting access to the first set of input terminals.

2. The loudspeaker interconnect terminal of claim 1, wherein:

the electrical switch is centrally disposed in relation to the terminal body between the first and second sets of input terminals; and

the switch cover has a range of motion along a lateral axis of the terminal body extending between the first and second sides.

3. The loudspeaker interconnect terminal of claim 2, wherein the range of motion of the actuator and the switch cover is limited to the extent of the second set of input terminals.

4. The loudspeaker interconnect terminal of claim 2, wherein the terminal body defines a pair of opposed tracks, along which the switch cover is slidably engaged.

5. The loudspeaker interconnect terminal of claim 1, wherein the switch cover reveals the first set of input terminals with the actuator in the second position, thereby allowing access to the first set of input terminals.

6. The loudspeaker interconnect terminal of claim 1, wherein the terminal body is defined by a top surface, the first and second sets of input terminals being mounted in a recessed relation thereto.

7. The loudspeaker interconnect terminal of claim 1, wherein:

the first set of input terminals are electrically connectible to at least a first one of the plurality of loudspeaker drivers; and

the second set of input terminals are electrically connectible to at least a second one of the plurality of loudspeaker drivers different from the first one of the plurality of loudspeakers.

8. The loudspeaker interconnect terminal of claim 1, wherein the first and second sets of input terminals each include a positive input terminal and a negative input terminal.

9. The loudspeaker interconnect terminal of claim 8, wherein the electrical switch is a double pole single throw type including a positive switch contact and a negative switch contact.

10. The loudspeaker interconnect terminal of claim 9, wherein the first positive input terminal is shorted to the second positive input terminal via the positive switch contact, and the first negative input terminal is shorted to the second negative input terminal via the negative switch contact with the actuator being in the first position.

11. The loudspeaker interconnect terminal of claim 9, wherein the first positive input terminal is electrically isolated from the second positive input terminal, and the first negative input terminal is electrically isolated from the second negative input terminal with the actuator being in the second position.

12. The loudspeaker interconnect terminal of claim 1, further comprising:

a circuit board with the electrical switch and the first and second sets of input terminals being electrically connected thereto;

13. The loudspeaker interconnect terminal of claim 12, wherein the circuit board further includes crossover circuitry.

14. The loudspeaker interconnect terminal of claim 12, wherein the circuit board further includes overload protection circuitry.

15. The loudspeaker interconnect terminal of claim 1, wherein each of the input terminals is selected from the group consisting of:

a universal binding post and a biased lever.
