Abstract
The utility model provides a wireless loud-speaker which is provided with a main machine and at least one subordinate loud-speaker, wherein the main machine is provided with a microphone, wireless receivers, a player, a cassette recording playback machine, a sound source amplifying circuit and a loudspeaker; the sound source amplifying circuit is provided with a wireless launcher; each subordinate loud-speaker is provided with one wireless receiver used for receiving sound sources transmitted from the wireless launcher of the main machine; and the subordinate loud-speaker is provided with the sound source amplifying circuit and the loudspeaker. Thereby, sound sources are transmitted to the wireless receiver of the main machine firstly; through the sound source amplifying circuit, sound is output by the loudspeaker; the subordinate loud-speaker can also be arranged at a plurality of different places; the wireless receiver of the subordinate loud-speaker receives the sound resources transmitted by the wireless launcher of the main machine; and then, sound is output by the loudspeaker through the sound source amplifying circuit. Thereby, the number of the subordinate loud-speaker can be increased or decreased according to place sizes to improve the defect that the volume of the single wireless loud-speaker is nonuniform.
Description
Technical field
The utility model relates to a kind of sound amplifier, particularly a kind of radio loudspeaker.
Background technology
General existing radio loudspeaker, mainly be in body, to be provided with wireless receiver, with wireless microphone transmission source of sound, receive by the wireless receiver in the body, again by the loudspeaker output that amplifies, yet, existing radio loudspeaker, it is the setting of the corresponding receiver of a reflector, when providing indoor rally or teaching to use, be subject to the restriction of receiving range, if the distance of reflector and receiver exceeds range of receiving, promptly can't receive source of sound and effectively export and enlarge sound, thus, promptly produce the disappearance of volume inequality, for example: the people other near sound amplifier can feel that volume is excessive, and apart from sound amplifier than remote location, the situation that then has the volume deficiency can not hear clearly.
Therefore, this creator is to concentrate on studies, improve, so initiate out the utility model because existing radio loudspeaker has as above-mentioned disappearance.
Summary of the invention
Main purpose of the present utility model is the defective that overcomes above-mentioned prior art, and a kind of setting that increases and decreases attached sound amplifier for cooperating the place size is provided, with a kind of radio loudspeaker of the disappearance of improving single wireless sound amplifier volume inequality.
In order to achieve the above object, the technical solution adopted in the utility model is: be provided with a main frame, described main frame is provided with microphone, wireless receiver, player, cassette recording playback machine, source of sound amplifying circuit and loudspeaker; The source of sound amplifying circuit of main frame is provided with wireless launcher again; Also comprising at least one attached sound amplifier, is the sound amplification function equipment that is attached to main frame, and each attached sound amplifier is provided with wireless receiver, source of sound amplifying circuit and loudspeaker.
The beneficial effects of the utility model are: can increase and decrease the setting of attached sound amplifier for cooperating the place size, improving the disappearance of single wireless sound amplifier volume inequality, and and then improve the quality of meeting or teaching.

Embodiment
Below in conjunction with accompanying drawing, be described in more detail with other technical characterictic and advantage the utility model is above-mentioned.
At first, please cooperate consult shown in Figure 1, the utility model mainly is provided with main frame 1 and at least one attached sound amplifier 2 of a radio loudspeaker, wherein said main frame 1 is provided with microphone 11, wireless receiver 12, player 13, cassette recording playback machine 14, source of sound amplifying circuit 15 and loudspeaker 16, in addition, source of sound amplifying circuit 15 is provided with wireless launcher 17 again, and wireless launcher 17 is provided with antenna 170 again; Attached sound amplifier 2, be the sound amplification function equipment that is attached to main frame 1, each attached sound amplifier 2 is provided with wireless receiver 21, source of sound amplifying circuit 22 and loudspeaker 23, wherein wireless receiver 21 is provided with reception antenna 210 again, is the source of sound that the antenna 170 for the wireless launcher 17 that receives main frame 1 is transmitted.
During use, please cooperate and consult shown in Fig. 1,2, source of sound mainly is to import main frame 1 earlier, no matter the speaker arranges in pairs or groups on the A of dais is used microphone 11 to deliver a speech, or provide main source of sound by the player 13 or the cassette recording playback machine 14 of main frame 1, the wireless receiver 12 that source of sound at first is sent to main frame 1 receives, again through source of sound amplifying circuit 15 by loudspeaker 16 output sounds, this moment main frame 1 can be synchronously as the function of sound amplifier; Moreover, the institute in visual again rally place must, at some diverse locations place attached sound amplifier 2 is set again, and the wireless launcher 17 set corresponding to main frame 1 of the wireless receiver 21 that makes each attached sound amplifier 2, so, make source of sound can transfer to corresponding attached sound amplifier 2 through wireless launcher 17, antenna 170 again, the antenna 210 by wireless receiver 21 receives again, after importing attached sound amplifier 2, again through source of sound amplifying circuit 22 by loudspeaker 23 output sounds.
Thus, transmit wireless receiver 21 modules of source of sound by wireless launcher 17 modules of a main frame 1 to the corresponding some attached sound amplifier 2 of collocation, to export by loudspeaker 23 after the source of sound processing and amplifying again, source of sound can be exported by the attached sound amplifier 2 that is arranged at diverse location, can effectively improve the disappearance of existing single wireless sound amplifier volume inequality, and then improve the quality of meeting or teaching.
Via above explanation, the utility model has reached desired purpose and effect really as can be known, and is to be initiative in ware, and the application important document when meeting novel patent proposes patent application in accordance with the law.
More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection range of the present utility model.
