The loudspeaker box according to the invention can simultaneously the sound signals from a wireless microphone and a IR microphone amplified and amplified by the amplifier circuit board be output from the speaker, resulting in a stable sound quality and a high output power can be achieved. In addition, the loudspeaker box according to the invention only an A4 format and can be thus easy to carry around.

State of technology

Known wireless loudspeaker box has a radio receiver in the housing, which can receive the sound signals from a wireless microphone, which then be output from the speaker. If two wireless microphones can be used simultaneously, an interference may occur so that one Noise is generated. Wireless speaker box with an IR receiver is Also known to receive the sound signals from an IR microphone can then be output from the speaker. The wireless Loudspeaker box with IR receiver has the same problem as the wireless speaker with Radio receiver.

Out For this reason, in view of the disadvantages of the present inventor Solutions, based on longtime Experience in this area, after a long study, numerous experiments and unceasing improvements to the present invention.

Task of invention

Of the Invention is based on the object, a portable wireless speaker to create, consisting of a main body inside a Recording room, provided in the positioning elements and a battery compartment are that can accommodate a battery and provided with a lid is on the back wall of the main body located on the back wall several knobs, a power switch and a CD front panel, on the front a handle and feet on the bottom; a sensor, which is arranged under the handle in the main body; one Volume control circuit board, the several control buttons that has with the knobs on the back wall of the main body are connected; an amplifier circuit board, those in the main body is arranged; a radio receiver circuit board and an IR receiver Circuit board in the main body are arranged; a front panel, which is arranged at the front of the main body is provided with a light filter and a filter network, wherein fastened to the inside of the filter network a speaker is; and a CD player, which is located behind the back wall in the main body is.

Further Details, features and advantages of the invention will become apparent the following detailed description of the preferred embodiments in conjunction with the attached drawings.

Ways to execute the invention

• aus einem Hauptkörper 1, der im Inneren einen Aufnahmeraum 10, in dem Positionierelemente 11 und ein Batteriefach 12 vorgesehen sind, das eine Batterie 13 aufnehmen kann und mit einem Deckel 14 versehen ist, der sich an der Rückwand des Hauptkörpers 1 befindet, an der Rückwand mehrere Drehknöpfe 15, einen Stromschalter 16 und eine CD-Frontplatte 17, auf der Stirnseite einen Handgriff 18 und auf der Unterseite Füsse 19 aufweist;
• einem Sensor 2, der unter dem Handgriff 18 im Hauptkörper 1 angeordnet ist,;
• einer Lautstärkeregler-Schaltungsplatte 3, der mehrere Regelknöpfe 30 aufweist, die mit den Drehknöpfen 15 an der Rückwand des Hauptkörpers 1 verbunden sind;
• einer Verstärker-Schaltungsplatte 4, die im Hauptkörper 1 angeordnet ist;
• einer Funkempfänger-Schaltungsplatte 5 und einer IR-Empfänger-Schaltungsplatte 6, die im Hauptkörper 1 angeordnet sind;
• einer Frontplatte 7, die an der Vorderseite des Hauptkörpers 1 angeordnet ist und mit einem Lichtfilter 70 und einem Filternetz 71 versehen ist, wobei an der Innenseite des Filternetzes 71 ein Lautsprecher 72 befestigt ist; und
• einem CD-Spieler 8, der hinter der Rückwand im Hauptkörper 1 angeordnet ist.

Like from the 1 . 2 and 3 it can be seen, the invention consists

• from a main body 1 inside a reception room 10 in which positioning elements 11 and a battery compartment 12 are provided, which is a battery 13 can take up and with a lid 14 is attached to the rear wall of the main body 1 located, on the back wall several knobs 15 , a power switch 16 and a CD front panel 17 , on the front side a handle 18 and on the bottom feet 19 having;
• a sensor 2 that under the handle 18 in the main body 1 is arranged;
• a volume control circuit board 3 , the several control buttons 30 that has with the knobs 15 on the back wall of the main body 1 are connected;
• an amplifier circuit board 4 that in the main body 1 is arranged;
• a radio receiver circuit board 5 and an IR receiver circuit board 6 that in the main body 1 are arranged;
• a front panel 7 placed at the front of the main body 1 is arranged and with a light filter 70 and a filter network 71 is provided, wherein at the In side of the filter network 71 a loudspeaker 72 is attached; and
• a CD player 8th behind the back wall in the main body 1 is arranged.

When mounting, as in the 1 . 2 . 3 and 4 is shown, first the sensor 2 under the handle 18 in the main body 1 attached. This will turn on the volume control circuit board 3 , the amplifier circuit board 4 , the radio receiver circuit board 5 and the IR receiver circuit board 6 in the main body 1 brought and by means of the positioning elements 11 positioned. Then the speaker 72 on the inside of the filter net 71 the front panel 7 attached. After that, the battery becomes 13 in the battery compartment 12 of the main body 1 brought and from the lid 14 in the battery compartment 12 locked. Finally, the CD player 8th in the main body 1 attached.

For use, the user only needs the power switch 16 Press, causing the radio receiver circuit board 5 Can receive audio signals from a wireless microphone. Through the knobs 15 that with the control buttons 13 of the volume control circuit board 3 connected, the volume can be controlled. These sound signals are transmitted through the amplifier circuit board 4 amplified and from the speaker 72 output. When an IR microphone is used, the sound signals pass through the light filter 70 the front panel 7 from the sensor 7 detects the detected sound signals to the IR receiver circuit board 6 sends. These sound signals are transmitted through the amplifier circuit board 4 amplified and from the speaker 72 output. The power required for operation is provided by the battery 13 supplied, whereby the speaker according to the invention is portable. The loudspeaker box according to the invention can simultaneously receive the sound signals from a radio microphone and an IR microphone passing through the amplifier circuit board 4 amplified and from the speaker 72 can be output, whereby a stable sound quality and a high output power can be achieved. Since the transmission frequency is different in radio transmission and IR transmission, interference can be avoided. In addition, the loudspeaker box according to the invention has only an A4 format and can thus easily carry around.
