Description
Technical field
The utility model relates to a kind of reception and sound-producing device of wireless local broadcast system, specifically a kind of radio broadcasting integral type loudspeaker.
Background technology
At present, in some public arenas as market, hotel, station, harbour etc., and vast rural area is all in a large amount of wired broadcast systems of using, in the market, public arenas such as hotel, station, harbour use broadcast system to broadcast information, enlightenment, advertisement, background music and emergent notice etc., and in the rural area, except can broadcasting information, enlightenment, advertisement, background music and emergent notice, also can play scientific and technological knowledge, weather forecast, farming activities, relay broadcast program etc., therefore, though in the city or the purposes of rural wired broadcasting very extensive.Existing wired broadcasting all is that the enlarger by the broadcasting station sends broadcast singal, make by lead and to be arranged in everywhere or the loudspeaker work of every family, not only circuit is long, influences attractive in appearance, installation inconvenience, the cost height, loss of signal is big, and circuit very easily damages, and needs often to change, and maintenance load is big, the connecting line of the wired broadcast system of public arena is concealed wire and arranges, in case damage then maintenance is more difficult.And in the rural area, not only circuit is long, and since the loudspeaker of this wired broadcast system must mate, exposed line transformer often is subjected to the erosion of wind and rain, and loudspeaker is very easily damaged.
In addition, in some more special occasions, also carry out work such as information issue, contact as fleet, fleet, taxi company etc., but the signal of this wireless broadcast system emission broadcasting station equipment is huge through wireless broadcast system commonly used, not only investment is big, and can't move.
Designed a kind of wireless broadcast system for addressing the above problem the applicant, and the utility model patent of having declared, need not lead between the cell site of this wireless broadcast system and each acceptance point is connected, and cell site's volume is little, cost is low, both can be used for fixing broadcasting, can be used for mobile broadcast again, be particularly suitable for all kinds of public places, vast rural area and mobile object such as fleet, fleet, the heavy construction building site, use in area such as explosion class mine, simultaneously again because the characteristics of broadcast signal receiver, make and to link to each other with broadcast signal receiver, the loudspeaker of using as sounding has saved exposed, the line transformer that very easily is subjected to the erosion of wind and rain and damages, the useful life of having improved loudspeaker.But since broadcast signal receiver and loudspeaker for dividing body structure, use and install not too convenient, after needing to install respectively again the lead with certain-length link to each other, faults such as broken string take place easily.
Summary of the invention
The purpose of this utility model is the problem of installing, existing in the use at the receiver in the above-mentioned wireless broadcast system and loudspeaker, and the coupling system characteristics design a kind of radio broadcasting integral type loudspeaker.
Technical solution of the present utility model is:
A kind of radio broadcasting integral type loudspeaker, the reception and the sounding that are used for the wireless local broadcast system, comprise the loudspeaker that the broadcast signal receiver that receives usefulness and sounding are used, loudspeaker is by broadcast signal receiver driving work, loudspeaker comprises the loudspeaker housing, is arranged in the loudspeaker core of loudspeaker housing and the loudspeaker magnet that links to each other with the loudspeaker core, loudspeaker magnet is provided with the installation screw, it is characterized in that broadcast signal receiver is installed in the shell, shell is provided with connecting bolt, and connecting bolt links to each other with installation screw on the loudspeaker magnet; Horn wire links to each other with the output of broadcast signal receiver in being installed in shell by lead.
In order to guarantee reception, the utility model is equipped with reception antenna on the shell that broadcast signal receiver is installed, and reception antenna links to each other with the input of broadcast signal receiver.
Reception antenna can be telescopic telescopic antenna.
The beneficial effects of the utility model:
1, simplified the structure of the receiving terminal of wireless broadcast system, by linking to each other with the screw that is connected that loudspeaker magnet itself is had with the connecting bolt that shell holds together, independently the parts change is as a whole to make two of scripts, realized incorporate purpose, saved installing space, make receiving terminal installation, use more easy.
2, simple in structure, easily manufactured, do not change the structure and the performance that have loudspeaker now.
3, broadcast signal receiver is reduced greatly with the conductor length that is connected between the loudspeaker, save cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of radio broadcasting integral type loudspeaker, the reception and the sounding that are used for the wireless local broadcast system, comprise the loudspeaker 2 that the broadcast signal receiver 1 that receives usefulness and sounding are used, loudspeaker 2 is by broadcast signal receiver driving work, loudspeaker 2 comprises loudspeaker housing 3, is arranged in the loudspeaker core 4 of loudspeaker housing and the loudspeaker magnet 5 that links to each other with the loudspeaker core, loudspeaker magnet 5 is provided with the installation screw, it is characterized in that broadcast signal receiver 1 is installed in the shell 6, shell 6 is provided with connecting bolt 7, and connecting bolt 7 links to each other with installation screw on the loudspeaker magnet 5; Horn wire 8 links to each other with the output of broadcast signal receiver 1 in being installed in shell 6 by lead.On the shell 6 that broadcast signal receiver is installed reception antenna 9 is installed, reception antenna 9 is telescopic telescopic antenna, and it passes shell 6 and links to each other with the input of broadcast signal receiver 1.Shell 6 is a sealed construction, and waterproof construction all should be adopted in the lead manhole appendix on it, power line manhole appendix and the through hole that installs reception antenna 9.
