Detailed description of the invention:

See Fig. 1-5, wireless acoustics part is lamp base, also be a flowerpot, its flowerpot contains built-in 4400mAh lithium battery, left and right acoustic channels loudspeaker, PCB circuit main board, Based Intelligent Control button plate, working station indicator 1, power switch 7, M.USB charge port 9, TF card socket 10, AUX Audio input jack 8.Lamp stand part be " cactus " of a kind on flowerpot its be a underpass turning joint 12 with flowerpot junction, for the connection of wire between circuit through this joint, when supporting also for using, adjust lamp stand angle (see Fig. 4).Its first segment " cactus " 13 inside installs 3W planar light source LED drive circuit circuit board.Second section " cactus " 14 is divided into 2 lobe designs, one lobe is fixed with first segment disjunctor, for installing perpetual calendar electronic clock and backlight LED light source, another lobe is connected with fixed lobes by upper threading turning joint 11, and this movable flap is also desk lamp lighting source, adopts integrated planar LED, its structure is by 1/2 " cactus " leaf lobe body, heat sink, LED light source, acrylic printing opacity reticulate pattern panel composition (see Fig. 4, Fig. 5).

Circuit solutions:

The utility model table lamp circuit sound equipment part adopts CSR BC05 stereosonic blue tooth 2.1+EDR module as wireless receiving, signal transacting, transmission, there is the excellent honest and clean capacitive of mobile phone, good echo cancellor and noise suppressed performance, 16-bit stereo audio coding, supports the decodings such as CSR.MP3, receiving sensitivity can reach: 85dBm, supports multiple bluetooth applications agreement.

Audio frequency enlarge leadingly, adopts low noise preamplifier MC4558 integrated circuit, has high voltage gain, Db106, Db, low-power consumption, maximum power dissipation≤400mW.

Power amplifier adopts: PAM8403 integrated circuit, the stereo D audio frequency amplifier of reactive filter, PAM8403 can with provide under 4 Ω loads higher than: the efficiency of 85% up to: 2 × 3W power output, possesses output short-circuit, overheat protection safety function.

4 Ω/3W full range high-fidelity loudspeakers when loudspeaker adopt 2 Cushions 1.5, for promoting bass effect, base " flowerpot " bottom design installs suspension low frequency radiation device (bass oscillating plate), the echo that sound downward radiation is produced promotes radiator (oscillating plate), thus obtain the high pitch that enriches, also bring the subwoofer audio (see Fig. 6) of shock.

Perpetual calendar clock adopts low-power consumption special clock module, and ultra-thin display display screen increases Blue backlight LED light source, makes night vision more clear attractive in appearance.

Electric power system: adopt 3.7V/4400mAh environmental protection lithium battery to become the needs of different magnitude of voltage with power management IC design as supply power supply (all same power supply of sound equipment, illumination, clock), make not produce interference between system, have more stability.

Illumination LED drive circuit adopts: LM3478 high efficiency low power consumption N channel switches type adjustment control integrated circuit is as core component, external metal-oxide-semiconductor makes it work in PWM current-mode, boost to: 9.6V is applicable to planar LED light source works voltage simultaneously, improve voltage and can reduce output current thus obtain low heating effect.And there is output short circuit protection, heat protection function.Intelligent switching control circuit adopts: CD4017 integrated circuit and peripheral cell composition, CD4017 is 5 Johnsom calculators.There is multiple decoding output and CP.CR.INH input, utilize this integrated circuit features, coordinate peripheral circuit to form a circulating single-button and complete the LED intelligent control circuit that fourth gear controls light modulation, form complete constant current mode LED drive circuit with LM3478.

Operation instruction:

The LED drive circuit of multi-function desk lamp, the circuit of bluetooth module, perpetual calendar clock is all extremely low power dissipation components and parts, the stand-by power consumption of LED drive circuit and bluetooth module is: uA level, perpetual calendar clock works in several milliamperes of current status, therefore without the need to arranging power switch, to ensure clock not power-off, guarantee that the time is accurate.Lighting operation: first, lamp socket " flowerpot " front button , click, the low light level, then one presses, high light, then clicks: mini light night, then click, turn off the light, circulate according to this.Perpetual calendar clock every display operation is identical with existing electronic clock, without the need to special introduction.LIGHT button is backlight switch button.

Sound equipment operates: be allocated to by lamp socket " flowerpot " sound equipment power switch behind: 0N position, length is pressed key, Bluetooth circuit is started shooting, at this moment, and status indicator lamp (from left to right), LED1 can flash once, then LED2 blue lamp can flash fast, represents that bluetooth is in accepting state, if connect upper bluetooth equipment, the sound that loudspeaker can send beep moves, simultaneously blue led 2 can become and flashes at a slow speed, represents that Bluetooth receptions module sets up pairing wireless connections with bluetooth equipment, at this moment can operate the song that you want to listen and play by the audio player in mobile phone. bond distance, by being open and close machines, shortly to suspend by for playing, bond distance adds by for volume, short in being a song, bond distance is by being volume down, short in being a upper song.LED3 redness is charger built-in lithium battery charging indicator light (any charger for mobile phone all can use) in this equipment.

TF card socket, under be loaded with music TF card use, insert TF card, circuit can identify automatically, without the need to conversion operations, automatically can enter the song on broadcasting TF card.

AUX socket can be used for the audio signal of external any MP3 format, and access external audio signal, circuit also can identify automatically, automatically can enter into the broadcasting of outer signal.
