Abstract
The utility model relates to a sound selector for remote control sound boxes or power amplifiers, which is used for achieving the sound selection between a power amplifier and a plurality of sound boxes, or a plurality of power amplifiers and a pair of sound boxes, or a plurality of power amplifiers and a plurality of sound boxes. The sound selector comprises a box body, at least a pair of input/output terminals on the box body, and a remote control receiving actuator which is positioned between the terminals and corresponds to a remote controller outside of the box body, wherein, the actuator comprises a receiving head, a logic switching circuit, an amplifying/driving circuit, a final control relay and a power supply. The sound selector can achieve remote controlled sound selection without the need of repeated artificial wiring, and can achieve the optimal comparative effectiveness of the sound selection.
Description
The utility model belongs in a kind of electronic audiovideo goods audio amplifier and power amplifier audition and relatively uses device.
For the people of development audio amplifier and power amplifier an important ring be audition relatively, comprise oneself product carried out longitudinal comparison and to the lateral comparison of other brand products.Also need the commodity of different brands are carried out lateral comparison for the shop of selling audio amplifier and power amplifier, select for client.
Can select to listen one of two pairs of audio amplifiers by the switch on the panel except that the power amplifier of individual brand in the past, the selector that does not also have a kind of special use, most of choosing process of listening is finished by rewiring, this method is not only wasted a large amount of time and manpower, and wiring choosing is listened and is easy to burn power amplifier repeatedly, simultaneously since the time interval that wiring produces will influence the effect and the accuracy of contrast audition greatly.
The purpose of this utility model provides and does not a kind ofly need artificial wiring repeatedly can contrast remote control voic box/power selector that choosing is listened.
This is novel comprise a box body and on the input and output terminal, it is characterized in that being provided with a pair of terminal that inputs or outputs at box body one end, be provided with N to output or input terminal in box body both sides correspondence, input or output between terminal and output or the input terminal and connect with the remote control receiving actuator, this remote control receiving actuator comprises that the remote control in the box body corresponding with the outer remote control transmitter of box body receives head, this reception head is successively through being relay with sending into actuator after logic translator and driving amplifier connect, with determine N to export or lead-out terminal in a pair of and input or input terminal UNICOM.
The utility model advantage is not need manually wiring repeatedly, only need the output and the input terminal connection of audio amplifier or power amplifier and this selector can be realized many remote controls choosings to audio amplifier are listened relatively, can not cause damage to audio amplifier or power amplifier, and do not influence choosing and listen comparative effectiveness, this selector can realize that also the choosing of a pair of audio amplifier logarithm platform power amplifier listens comparison simultaneously, and also available two selectors realize that several power amplifier logarithms to the selection butt joint of audio amplifier relatively.
The utility model concrete structure and embodiment accompanying drawings are as follows:
Fig. 1. remote control voic box/power amplifier selector external form floor map;
Fig. 2. remote control receiving actuator block diagram;
Fig. 3. (a) and (b) four tunnel monophony executor circuit figure.
As Fig. 1. shown in Figure 2, this selector comprises a box body 1, box body one end is provided with a pair of terminal 2 that inputs or outputs, be provided with N to output or input terminal 3 in box body both sides correspondence, input or output between terminal and output or the input terminal and connect with the remote control receiving actuator, this remote control receiving actuator block diagram as shown in Figure 2, comprise that remote control in the box body corresponding with remote controller 4 (remote control transmitter) receives 5, this reception head successively through with send into actuator N to relay 8 after logic translator 6 and driving amplifier 7 connect, with determine N in output or the input terminal a pair of with input or output terminal UNICOM, entire circuit is by power supply 9 power supplies.
Fig. 3 has provided a pair of monophony executor circuit figure in terminal and four pairs output or the input terminal selector (dual track adopts the same executor circuit of two-way to control) that inputs or outputs, select for use 50 type remote controllers and remote control to receive head among Fig. 3 (a), relay adopts three, and (this example is a special case, ordinary circumstance N adopts N that relay is carried out two-way control to terminal), when selecting A or B, relay J 1 is connected with the upper end, relay J 2 is connected with upper end or lower end, A or B in power amplifier or audio amplifier Z and audio amplifier or the power amplifier are connected, when selecting C or D, relay J 1 is connected with the lower end, J3 and upper end or lower end are that C or D connect, and realize that a power amplifier listens the choosing of 4 pairs of audio amplifiers.When reverse connection, can realize that also 4 power amplifiers listen the wherein situation of a power amplifier to a pair of audio amplifier to fetching choosing.As select two selectors for use, also can realize of the butt joint of 4 power amplifiers, so that the choosing of a power amplifier or a pair of audio amplifier is wherein listened to 4 pairs of audio amplifiers.
Fig. 3 (b) is four tunnel monophony actuator preferred circuits, and relay adopts 4.Can adopt the two-way executor circuit for dual track, promptly relay is selected 4 pairs for use.To output or input terminal situation, select for use N to N to relay.
