Abstract
The utility model discloses a device for automatically controlling and regulating volume. The device comprises a human body infrared sensor, a microprocessor and a digital volume regulator, wherein the human body infrared sensor is connected with the microprocessor through an amplifier; the microprocessor is connected with the digital volume regulator; when sensing the approaching of a human body, the human body infrared sensor generates a sensing signal, and the sensing signal is amplified by the amplifier and then transmitted to the microprocessor; and the microprocessor controls the digital volume regulator to perform volume regulation according to the sensing signal. Compared with the prior art, the device provided by the utility model can automatically regulate the volume of a counter display device and an advertisement display device according to the approaching or leaving of the human body; when the human body approaches, the volume is increased, and when the human body leaves, the volume is decreased; therefore, a display effect is effectively improved and energy waste is reduced.
Description
Technical field:
The utility model relates to a kind of Automatic control of sound volume adjusting device, is mainly used in occasions such as counter display, advertisement displaying.
Background technology:
At present in occasions such as counter display, advertisement displayings; Usually need to adopt display screen to play the recommendation advertisement and the product information of businessman; This displaying advertisement design belongs to fixed form, and the volume of its image that displays the play generally configures, and can't regulate or be merely able to and regulate through the special messenger.
There is following shortcoming in the mode that this counter display, advertisement are showed: if a volume is in big state, and when nobody near the time, the volume of its broadcast can not change, its energy-saving effect is bad, and environmental noise is bigger; Two, if volume is in less state, and as the people near the time, the volume of its broadcast can not become greatly, causes the unheard problem of user easily.
Summary of the invention:
For this reason, the purpose of the utility model is to provide a kind of Automatic control of sound volume adjusting device, is mainly used in occasions such as counter display, advertisement displaying, realize when the people near or away from the time, automatic regulating volume is big or small, satisfies environment and user's requirement.
For realizing above-mentioned purpose, the utility model mainly adopts following technical scheme:
A kind of Automatic control of sound volume adjusting device; Comprise human body infrared inductor, microprocessor and digital volume adjuster; Said human body infrared inductor is connected with microprocessor through amplifier, and said microprocessor is connected with digital volume adjuster, and said human body infrared inductor induction human body is near producing induced signal; After amplifier amplifies, send to microprocessor, microprocessor carries out volume according to this induced signal control figure volume adjuster to be regulated.
Wherein said microprocessor also is connected with a LED display.
The utility model through the human body infrared inductor human body near this device time generation induced signal;, amplifier sends to microprocessor after amplifying; Microprocessor carries out volume according to this induced signal control figure volume adjuster to be regulated; Reach human body near or away from the time, automatic regulating volume size satisfies environment and user's requirement.Compared with prior art, the utility model according to human body near or away from automatically the volume of counter display, advertising device being adjusted, reach the people near the time, it is big that volume becomes; Away from the time, volume diminishes, and effectively raises bandwagon effect, has reduced the waste of the energy.
Description of drawings:
Fig. 1 is the system block diagram of the utility model adjusting device.
Embodiment:
For setting forth the thought and the purpose of the utility model, will combine accompanying drawing and specific embodiment that the utility model is done further explanation below.
See also shown in Figure 1ly, Fig. 1 is the system block diagram of the utility model adjusting device.The utility model provides a kind of Automatic control of sound volume adjusting device, is mainly used in the problem that present counter display, advertising device volume can not be adjusted according to different environments for use and occasion that solves.
The described Automatic control of sound volume adjusting device of the utility model; Include human body infrared inductor, amplifier, microprocessor, digital volume adjuster and LED display; Said human body infrared inductor is connected with microprocessor through amplifier; Said microprocessor is connected with LED display with digital volume adjuster respectively; Said human body infrared inductor induction human body sends to microprocessor near producing induced signal after amplifier amplifies, microprocessor carries out volume according to this induced signal control figure volume adjuster to be regulated.
The human body infrared inductor be used for the induction whether have the people to install near this, as the people near the time, the human body infrared inductor can detect infrared signal; And with sending to microprocessor after this infrared signal process amplification; Microprocessor is analyzed according to this infrared signal, draw the people near information, and through this information Control numeral volume adjuster; The numeral volume adjuster is realized the adjusting to volume, makes volume become big; And when human body installed away from this, the infrared signal that the human body infrared inductor is detected disappeared, and this moment, no signal sent to microprocessor, and microprocessor then control figure volume adjuster is turned volume down, reaches purpose of energy saving.
More than be that a kind of Automatic control of sound volume adjusting device that the utility model is provided has been carried out detailed introduction; Used concrete example among this paper the structural principle and the execution mode of the utility model are set forth, above embodiment just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
Claims (2)
1. Automatic control of sound volume adjusting device; It is characterized in that comprising human body infrared inductor, microprocessor and digital volume adjuster; Said human body infrared inductor is connected with microprocessor through amplifier, and said microprocessor is connected with digital volume adjuster, and said human body infrared inductor induction human body is near producing induced signal; After amplifier amplifies, send to microprocessor, microprocessor carries out volume according to this induced signal control figure volume adjuster to be regulated.
2. Automatic control of sound volume adjusting device according to claim 1 is characterized in that said microprocessor also is connected with a LED display.
