Description

    The present invention relates to a loudspeaker using solar power generation, and relates to a system for loudening sound from a speaker by remotely operating a power switch of a specific low-power radio when necessary from a distance.

When installing outdoor speakers at a remote location in the school yard or factory premises, it was necessary to wire audio lines.
For example, if the operation panel or console of a broadcasting facility is installed indoors and speakers are installed at a remote location, some wiring such as embedding / exposure is required from the operation panel or console to the speakers. It was.
Also, in conventional broadcast facilities, there is an inconvenience that broadcasts can be performed only from the place where the microphone is installed in emergency call broadcasting and the like.

  Furthermore, there are wireless microphones for broadcasting while moving, but there are restrictions on behavior because radio waves reach only within a narrow range. In addition, if the broadcasting can be maintained at any time, the broadcasting equipment must be turned on at all times, so a hum or noise is generated from the speakers, and further standby power is consumed. There was a problem.

When installing broadcasting speakers in a large factory or school site, install them in the corner of the school or factory building away from the building, and consider the direction of the sound in the direction of the building, that is, from the site. It is common to install a speaker facing inward. However, in such an arrangement, the distance from the broadcasting facility to the speaker is increased, and wiring work is expensive. Therefore, the speaker is often attached to a wall, a pillar, or a pillar of a building near the broadcasting facility.

Therefore, in such a case, since the speaker is attached toward the outdoor direction in the school yard or factory, there is a problem that the sound flows in the outward direction of the site and the nearby residents are disturbed as noise.

In addition, when broadcasting, it was impossible to broadcast unless it went to the broadcast room or the place where the microphone was installed.

In the present invention, in order to solve these problems, a speaker, an antenna, a low-power radio receiver, an output amplifier, and the like are attached to a pole on which a photovoltaic power generation panel is attached, and the pole is equipped on one pole. Independent broadcasting facilities.

The microphone that conveys voice uses a portable low-power radio transmitter, that is, a transceiver (3), and receives a fixed low-power voice via a voice reception antenna (4) attached to a pole (8). The voice converted by the voice receiver (13) is amplified by the speaker (5) by the output amplifier (14).

In addition, the present invention prevents the hum and noise coming out of the speaker by turning off the power when the broadcast is stopped, and can prevent deterioration of the device due to battery consumption or energization or lightning strike, so it is provided on the pole. The solar power generator shall be cut off from the broadcasting equipment except for a part.

Therefore, as a method for turning the power ON / OFF, a portable button switch type low-power radio transmitter, that is, a switch transmitter (1) is used, and a push button ON switch (17) is used to push the switch receiving antenna. (2) Via a fixed low power switch receiver, that is, a push button switch receiver (11), the power switch (12) is operated from its output contact to turn on or off the power of the broadcasting equipment It is to make.

Therefore, the transceiver (3) and the switch transmitter (1) are carried as a set, and the push button ON switch (17) of the switch transmitter is operated immediately before broadcasting, and then the sound is emitted toward the transceiver. Broadcasting is possible. In addition, after the broadcast ends, the power is cut off by operating the push button OFF switch (18) of the switch transmitter.

In addition, if the broadcast facility is still in the ON state due to forgetting to operate the push button OFF switch of the switch transmitter, etc., if the silent state continues for a certain period of time, the timer (16) pushes the push button. The power supply circuit is automatically shut off in the same way as when the button is pressed.

As described above, the present invention is a broadcasting system that combines existing radio equipment, broadcasting equipment, and solar power generation, but is not a mere combination, but organically combines the different functions of each. Because there is no need for speaker wiring or power supply wiring, there is no restriction on the installation position other than sunlight, and it is possible to install the speaker facing inward so that the sound does not affect the outside as noise. is there.

Furthermore, in the present invention, the power supply can be turned on only when necessary, and can be turned off when unnecessary. Therefore, if there is a sign of lightning strike, it can be avoided if it is turned off. In addition, there is an effect of reducing deterioration of equipment due to long-time power supply.

Furthermore, if you carry the switch transmitter (1) and the transceiver (3), you can broadcast from almost any place within the reach of the radio waves in the schoolyard or campus, and if you have multiple transceivers, It is also possible for people to broadcast.

Therefore, in the case of the conventional type, it was necessary to rush to the place where the power switch of the broadcasting facility is located in an emergency and to turn on the broadcast, but in the present invention, there are the switch transmitter (1) and the transceiver (3). It is possible to broadcast from anywhere where radio waves reach, and it is possible to broadcast immediately even when an emergency occurs.

A plurality of switch transmitters (1) and transceivers (3) are more effective.
