Abstract
The utility model relates to a multifunctional infrared voice sounding device, which is composed of a transmitter and a receiver, wherein, an infrared transmitting device in the transmitter is composed of a pulse oscillating circuit, an amplifying circuit and a transmitting tube; an infrared-control voice sound-producing device in the receiver is composed of a receiving tube, an amplifying circuit for a received signal, a decoder, a voice integrated circuit, a voice amplifying circuit and a loudspeaker. The transmmiter and the receiver are respectively arranged at both sides of an entrance; when customers go in and out, the bodies of the customers shield a transmitting window of the transmitter; the loudspeaker can automatically send out sounds. The utility model can be served as a welcome device or an alarm.
Description
The utility model relates to a kind of multi-functional infrared voice generators that uses in commercial and service trade.
At present, deepening continuously and develop along with market economy, the language that greets a guest that the broadcast that commercial and service trade arranges to specialize in the waiter of welcome's work in the porch of sales department or uses playback set not stop records in advance is to reach the purpose that stays good influence to client.But being equipped with special Hotel Greeter for some small-sized sales departments, is a no small spending to sales department, and the language that greets a guest that continuous broadcast records in advance seems very noisy again.
The purpose of this utility model is at the problems referred to above, designs a kind of multi-functional infrared voice generators that can automatically play the language that greets a guest when client enters sales department.
The purpose of this utility model realizes in the following way: a kind of multi-functional infrared voice generators of the present utility model is made up of transmitter and receiver two parts, transmitter has a shell, there is a hole to make launch window on the shell, also has a power switch on the shell, infrared launcher and power supply are arranged in the shell, receiver has a shell, there is a hole to make receive window on the shell, also has a power switch on the shell, infrared control sound generating mechanism and power supply are arranged in the shell, infrared launcher in the transmitter is the pulse oscillation circuit that is made of integrated package Resistor-Capacitor Unit peripheral with it, amplifying circuit and power valve are formed, the output terminal of pulse oscillation circuit is connected with the input end of amplifying circuit, the output terminal of amplifying circuit is connected to power valve, infrared control sound generating mechanism in the receiver is by receiving tube, the received signal amplifying circuit, the demoder that integrated package Resistor-Capacitor Unit peripheral with it constitutes, speech IC, voice amplifying circuit and loudspeaker are formed, receiving tube is at the input end of received signal amplifying circuit, the output terminal of received signal amplifying circuit is connected with the input end of demoder, the output terminal of demoder is connected with the trigger end of speech IC, the output terminal of speech IC is connected with the input end of voice amplifying circuit, is connected to loudspeaker on the output terminal of voice amplifying circuit.The integrated package that constitutes pulse oscillation circuit is HD74HCOOP; The integrated package that constitutes demoder is LM567.
Above-mentioned multi-functional infrared voice generators is in running order when the power switch of transmitter and receiver is closed simultaneously, at this moment, the infrared launcher of transmitter is launched infrared electro signal by power valve by the pulse signal of pulse oscillation circuit generation certain frequency after amplifying circuit amplifies.The receiving tube of the infrared control sound generating mechanism in the receiver receives this infrared electro signal after send into the input end of demoder after the amplification of received signal amplifying circuit, the centre frequency of adjusting demoder is consistent with the pulse signal frequency that the pulse oscillation circuit of transmitter produces, at this moment, demoder is output as low level, the trigger end Triggerless of speech IC, loudspeaker is sounding not.When the launch window of transmitter is blocked, receiver does not receive signal, demoder is output as high level, the trigger end of speech IC is after triggering, output terminal output voice signal at speech IC, this voice signal promotes loudspeaker and sounds, as terms of courtesy such as " welcome ", " thank you for coming " after the voice amplifying circuit amplifies.The transmitter of multi-functional infrared voice generators of the present utility model and receiver are split both sides in the porch, when client passes in and out, health blocks the launch window of transmitter, and the receive window of receiver does not receive signal, and loudspeaker will be sounded automatically.Therefore, multi-functional infrared voice generators of the present utility model can be used as the guest greeting device use.As multi-functional infrared voice generators of the present utility model is placed on the warehouse, promptly can be used as alarm and use.
