Abstract
A team smart explanation receiver is a device which can be used in indoor venues, and can carry out automatic wireless receiving and voice-amplified broadcasting. The internal function modules of the team smart explanation receiver is mainly composed of an audio signal collector, an eight-way audio intelligent optimization module, an MCU control module, an audio power amplifying module, an audio switching device, a power source part, and an automatic adapter; and the external portion of the team smart explanation receiver is composed of each adjusting button, a 220V-power source input port and a voice-amplifying loudspeaker. After audio signal receiving and a series of transformation, voice can be amplified and broadcasted through the audio power amplifying module and the audio switching device. The team smart explanation receiver has the following advantages that: the team smart explanation receiver can be fixed in a venue; volume and pitch can be controlled through a wireless remote controller, or the number of the team smart explanation receiver and the voice-amplifying loudspeaker can be increased so as to enable the voice to cover a whole space; after being processed, broadcasted voice can be clear; and further, the team smart explanation receiver is particularly suitable for being used in venues such as planning museums, memorial halls and museums.
Description
Technical field
The utility model relates to a kind of explanation equipment that amplifies that indoor venue uses that is fixed on, and particularly can carry out team's wisdom explanation receiver that automated wireless receives and amplifies and play.
Background technology
In recent years, fast development along with the cultural tour cause, country has also released a lot of support policies, the necessary condition of using electronics explanation equipment as museum's grading, and planning exhibition center, museum, the memorial museum of concrete characteristic are also all built in the area, each province and city in effort, and the concept of wisdom tourism is also brought into schedule.At present, most of venue is using terminal explanation equipment, but this kind equipment uses for individual visitor, when we advocate the wisdom tourism energetically, people have often ignored in the mode of present tourism, team's tourism occupies very large ratio, how to improve the service quality of team's tourism, and wisdom, the technicalization that promotes venue is also the part in the wisdom tourism.
The utility model content
In order to solve the demand, the utility model has been designed and developed and has a kind ofly been offered that the visitor of team uses, the explanation equipment that can carry out wireless automatic reception and amplify and play, by receiving the signal of transmitting terminal emission, after transforming, by the loudspeaker broadcast that amplifies, simultaneously, can also automatically regulate corresponding frequency range, have play sound clarity, automatic adaptation regulate sensitive, the sound coverage is large and but wireless remote control is controlled, be need not manually operated characteristics, is very suitable for the use of the indoor venues such as museum, planning shop, memorial museum.
The technical solution of the utility model is achieved in that
1) a kind of team wisdom explanation receiver is by the receiver shell, each functional module and control circuit thereof in housing, megaphone forms, mains switch is arranged on shell, each input and output connector, internal control circuit is mainly by the audio signal sample device, 8 road audio intelligent preferred module, the MCU control unit, audio frequency power amplifier module, audio switch, power unit, the automatic adaptation device forms, the MCU control unit is main functional module, respectively with are connected module connection work, the audio signal sample device gathers 8 tunnel audio signals, the automatic adaptation device is controlled the automatic adaptation that carries out channel by the MCU control unit.
2) power unit adopts the 220V AC-powered, and is reliable and stable.
3) each input and output connector comprises connector, the power supply connector of the connector of external loudspeaker, external public broadcasting.
4) external megaphone can for ceiling type, wall-hanging, suspension type etc., facilitate the venue choice for use.
5) volume adjusting is that wireless remote control is controlled, and controls volume, tone etc. by the mode of wireless remote control, and is easy to operate.
This utility model designs compared with prior art, and its advantage is:
1) the low Radio Transmission Technology that postpones of this equipment utilization numeral by receiving the wireless signal of transmitting terminal, is play after will sound enlarging again, sound clarity, reaches hi-fi effect, and the sound coverage is large.
2) this equipment can be regulated segment number frequently automatically by automatic adaptation device and MCU control unit, to adapt to the frequency range of transmitting terminal.
3) more than this equipment can be supported 200 explanation passages simultaneously, and can arrange simultaneously many these equipment in same venue, to reach the user demand of different spaces size.
4) this equipment can gather the wireless audio signal of a plurality of different azimuth by the audio signal sample device, the building, the old exhibition layout structure that coordinate venue, the shadow region of eliminate signal reflection, scattering affects, and can improve receiving sensitivity and the stability of wireless signal.
5) this equipment is processed in real time 8 road audio signal sample data flow, and expanding channel capacity utilizes the redundancy of appropriate design to promote the reliability of wireless data link.
6) this equipment can hiddenly be installed, and the installing engineering interface is little.
7) volume, tone etc. can be controlled by wireless remote control, and be easy to operate.
8) supporting megaphone can be selected multiple pattern, the modes such as placed type, ceiling type, suspension type, and venue can be selected different loudspeaker mounting meanss according to the different demands of oneself.
9) this equipment adopts the 220V ac power supply, and supply power mode is stable, reliable.
this utility model is skillfully constructed, the equipment that amplifies is designed to a kind of segment number frequently that can automatically adjust, and the wireless receiving mode that amplifies and play, when realizing team's explanation, sound enlarges the effect of playing, simultaneously, this equipment can be arranged to frequency ranges different more than 200, do not interfere with each other when different museums use at the same time to adapt to, and volume, tones etc. can carry out the wireless remote control regulating and controlling, the new model that a kind of team explains the playback equipment that amplifies has been started in this invention, a kind of wisdom, hommization, team's wisdom explanation receiving equipment of high-technicalization.
Description of drawings
Fig. 1 is team's wisdom explanation receiver principle block diagram
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described:
According to Fig. 1, this team's wisdom explanation receiver is made of audio signal sample device, 8 road audio intelligent preferred module, MCU control unit, audio frequency power amplifier module, audio switch, automatic adaptation device, power unit.Outside has mains switch, 220V power supply input port, external public broadcasting input port and megaphone and consists of.
according to actual conditions, this team's wisdom explanation receiver is installed in museum, connect the 220V alternating current by power line, turn on the power switch, after the guide carries transmitting end equipment and enters this museum, the automatic adaptation device of receiver is controlled by the MCU control unit and automatically is adjusted to the frequency segment number that is complementary with transmitting terminal on the one hand, the audio signal sample device of receiver gathers 8 tunnel audio signals on the other hand, after 8 road audio intelligent preferred module screenings, control through the MCU control unit again, after processing, controlling audio frequency power amplifier module and audio switch amplifies audio signal, be transferred to after switching and carry out the outer of sound on megaphone and put.
