The portable wireless loudspeaker is characterized in that the loudspeaker also comprises an outer shell in a cylinder shape and with a closed bottom; a channel is opened on the outer shell and fixedly provided with a solar plate; the cable of the plate is introduced to the outer shell through the aforementioned channel; the end surface of the outer shell is a round wood board; the middle portion of the round wood board is provided with sound transmission nets; the loudspeaker body and the driving circuit of the loudspeaker are fixed in the outer shell; the outer shell is also fixedly provided with a control circuit and a conversion circuit of the solar plate and a frequency modulation-receiving circuit; the signal output terminal of the frequency modulation-receiving circuit is connected with the signal input terminal of the driving circuit of the loudspeaker; the control circuit and the conversion circuit of the solar plate provide working power supply for the aforementioned circuits respectively; the lower portion of the bottom of the outer shell is connected with a rubber vacuum chuck; and the vacuum chuck is provided with a vacuum-pumping channel passing through the chuck surface. The mounting positions of the loudspeaker can be can be adjusted according to the needs conveniently, thereby facilitating classroom teaching.
Description
Technical field
The utility model relates to a kind of utensil of raising one's voice that is applied in the teaching field.
Background technology
In order to satisfy the continuous expansion of college scale, there have been increasing teaching facilities modified, the needs of listening to the teacher in the hope of satisfying numerous students for example, are installed loud speaker in the classroom.But, along with the use of these new facilities, people find to exist following problem gradually: when number of student was few, loud speaker but was installed in position far away; When number of student is many, sometimes can find again laying apart from far away not of loud speaker.In addition, in some laboratories, serve as a teacher when needing to use loud speaker, but be difficult to timely installation.
Summary of the invention
In order to solve the technical problem of mentioning in the background technology, the utility model provides a kind of portable mobile wireless loud speaker, and this kind loadspeaker structure is simple, be easy to install, and low price can need to be adjusted very easily according to teachers the riding position of loud speaker, is convenient to classroom instruction.
The technical solution of the utility model is: this kind portable mobile wireless loud speaker, comprise loud speaker body and loudspeaker driving circuit, its unique distinction is: described portable mobile wireless loud speaker also comprises a shell columnar and bottom is sealed, have the duct at shell, be fixed with the solar energy pole plate on it, the cable of described pole plate is introduced in the shell by aforementioned duct, and the end face of described shell is round wood plate, and its central part is the sound net; Described loud speaker body and loudspeaker driving circuit are fixing in the enclosure, in addition, also be fixed with the control of solar energy pole plate and change-over circuit and FM reception circuit in the described shell, the signal output part of described FM reception circuit is connected to the signal input part of loudspeaker driving circuit, and described solar energy pole plate control and change-over circuit are respectively aforementioned circuit provides working power; Be connected with the vacuum cup of a glue system below the bottom of described shell, have a duct that vacuumizes of running through this chuck surface on the described vacuum cup.
In addition, can improve on the such scheme basis, the fold shape shirt rim is made in the shirt rim of described vacuum cup, like this, after vacuumizing, adhesive is effective.
The utlity model has following beneficial effect: this kind loud speaker is not fixed at fixing indoor location, can utilize solar energy to provide working power for cabinet speaker, utilizes simultaneously the sucked type base to realize arbitrarily location.Like this, the user is random mobile loud speaker as required, and a plurality of loud speakers are set in certain space, reaching preferably loud-speaking effect, thereby realizes and can not affected by power supply, is not subjected to the impact of environment size, reaches better audibility.During use, needs and the transmitter with radio reception circuit and radio-frequency transmissions circuit cooperate, sound during teachers is through the effect of radio reception circuit and radio-frequency transmissions circuit, voice signal is launched by radiating circuit after the FM modulation, like this, the FM reception circuit that is in far-end receives rear demodulation, is then amplified by power amplifier, drives at last the loud speaker sounding.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the principle of compositionality figure of the utility model circuit.
1-vacuum cup among the figure, the 2-shirt rim, 3-vacuumizes the duct, 4-end face, the saturating sound net of 5-, 6-shell, 7-solar energy pole plate.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this kind portable mobile wireless loud speaker, comprise loud speaker body and loudspeaker driving circuit, its unique distinction is: described portable mobile wireless loud speaker also comprises a shell 6 columnar and bottom is sealed, have the duct at shell 6, be fixed with solar energy pole plate 7 on it, the cable of described pole plate is introduced in the shell 6 by aforementioned duct, the end face 4 of described shell 6 is round wood plate, and its central part is sound net 5; Described loud speaker body and loudspeaker driving circuit are fixed in the shell 6, in addition, also be fixed with the control of solar energy pole plate and change-over circuit and FM reception circuit in the described shell 6, the signal output part of described FM reception circuit is connected to the signal input part of loudspeaker driving circuit, and described solar energy pole plate control and change-over circuit are respectively aforementioned circuit provides working power; Be connected with the vacuum cup 1 of a glue system below the bottom of described shell 6, have on the described vacuum cup 1 one run through this chuck surface vacuumize duct 3.
During use, the teacher needs the transmitter that radio reception circuit and radio-frequency transmissions circuit are installed, sound will be through being launched by radiating circuit after the FM modulation like this, demodulation after being in FM reception circuit in the wireless speaker of far-end and receiving, then amplified by power amplifier, drive at last the loud speaker sounding.
In addition, if tiny fold shape shirt rim is made in the shirt rim 2 of vacuum cup 1, vacuumizing so rear fixing effect can be better.
