Description

The electronics atmosphere is set off device by contrast

The utility model is the hand-hold electronic device that a kind of spectators cheer, and it can produce color, sound equipment and light synchronously and set off effect by contrast.

Spectators are in sports ground and performing art occasion, participate in refueling, cheer use generally be from cap, dress ornament to toy trumpet, sign this etc. apparatus, lack a kind of articles for use that can express own mood more energetically and promote Games-related atmosphere.According to general electronics basic principle, the speech IC principle, with reference to " novel electron luminescent device ", books such as " the Voice Record and PlaybackICs " of American I SD company.Conceive the electronics atmosphere and set off device by contrast.

The purpose of this utility model provides and a kind ofly can make spectators utilize color, sound equipment, light to express the electronics hand-held device of own mood.

The purpose of this utility model is achieved in that a kind of electronics atmosphere sets off device by contrast, is to be made of shell, pull bar, internal circuit, battery, switch, loudspeaker and microphone; Wherein be fixed with pull rod device on the shell, internal circuit has adopted the speech IC of the amount of level direct modeling more than memory technology, wherein, microphone MIC connects the mid point of change-over switch SW4, the REC end of SW4 is connected to MIC and the MICREF end of speech IC IC1 respectively by C4, C3, the MIC end of SW4 is connected to the positive-negative input end of power amplifier IC2, and is connected to SP+ and the SP-end of IC1 respectively by electric capacity, resistance C11, R12 and C12, the R13 of series connection; The output one tunnel of IC2 is connected to loudspeaker SP, and another road is connected to the input of the low pass filter that is made of R7, C7, and the output of low pass filter is connected to the input of driver BT1, and the output of BT1 is connected to luminescent device D2; The end ground connection of switch SW 1, SW2, SW3, the other end are connected to PL end, REC end and the PE end of IC1 respectively.Described shell shape can be football cup type or cards folder type.But internal circuit is the center with the speech IC of IC1 recording playback, when SW4 is put into the REC position, presses SW2, and the MIC microphone is collected and recorded on-the-spot voice and talk, and the direct IC of this signal sends into and stores.After SW3 pressed, the voice signal that is recorded among the IC1 was sent into IC2 power amplifier IC2 amplification, sounds by the SP loudspeaker; When SW1 presses, then can play the voice signal that is stored among the IC1 continuously.The voice signal of Fang Daing is given low pass filter simultaneously at the same time, picks up the low frequency signal that is lower than the 50Hz frequency, and after BT1 drove, the modulated luminescence device was realized along with the music rhythm blinking light.When SW4 pushed the MIC position, the voice signal that MIC records was directly delivered to IC2 and is amplified, and plays the sound of cheering of audience the same period, plays the effect of enlarger.

Owing to adopt such scheme, under the acting in conjunction of color, sound, light, realized the purpose of heighten atmosphere.Because of the use of large scale integrated circuit, peripheral capacitance resistance ware seldom, so internal circuit debugging is simple, contour structures is small and exquisite.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is front elevation and the vertical section structure figure that atmosphere is set off first embodiment football cup type of device by contrast.

Fig. 2 is front elevation and the vertical section structure figure that atmosphere is set off second embodiment cards folder type of device by contrast.

Fig. 3 is an internal circuit block diagram of the present utility model.

Fig. 4 is an internal circuit schematic diagram of the present utility model.

In Fig. 1, Fig. 2,1. shell 2. batteries 3. circuit boards 4. pull rod device 5. switches 6. microphone 7.SP loudspeaker 8. luminescent devices.One side of shell has been installed a pull rod device, can hang versicolor flag after pull bar is pulled out.

In the circuit theory diagrams embodiment illustrated in fig. 4, IC1 is a core component, it has adopted many level analog quantity memory technology, international, domestic all have a manufacturer production, can be ISD1100,1200,1400 series of products of ISD company, the APR9600 in Taiwan, products such as IVS1560 generally directly are encapsulated in IC wafer on the printed circuit board (PCB) with mask technique.During recording, SW4 pushes the REC position, presses SW2 (REC recording switch) switch, and the MIC signal is sent into IC1, the sound of record and storage song and talk.This moment, the RECLED end of IC1 was low level, and D1 begins to light, and prompting is recorded.The length of writing time is relevant with the device model.R2, R3, R4 form the biasing circuit of microphone (electret microphone), R3, and the R4 resistance is identical, can prevent common-mode noise effectively, can reduce the recording ambient noise of 10db than it single-ended MIC or the input of not having a biasing MIC.C3, C4 are the coupling capacitance of MIC, and its size has determined the LF-response of the preamplifier of IC1 inside.R8, R9, R10 are the pull-up resistor of IC1.R1, C1 form the passage that the inner preamplifier of IC1 outputs to the record buffer input of IC1 inside, and their size influences the frequency response of voice signal.SW1 (PLAYL) is the loop playback switch, played songs and music continuously after pressing.SW3 (PLAYE) switch is the edge-triggered switch, triggers once, for the beginning playback, triggers once for stopping playback again.C10 is the anti-shake noise electric capacity of recording switch SW3 when pressing.The effect of R5, C5 is a dynamic range of determining the inner AGC of IC1.The output audio signal of IC1 is delivered to IC2 (LM386) power amplifier by C11, C12 and R12, R13, amplifies and exports to SP (loudspeaker) playback again.This signal is via R7 simultaneously, and C7 forms low pass filter, picks up low frequency signal, and it is luminous to drive luminescent device D2 through BT1.Luminescent device can adopt wavelength in visible-range, and the special superhigh brightness LED of luminous intensity more than 1000mcp under the darker condition of scene, can throw nearly about five meters.
