Embodiment

The utility model embodiment is as follows:

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.

The utility model is a kind of novel intelligent guitar, and its fingerboard 1 comprises panel, and pcb board 2 and backboard, pcb board is clamped between panel and backboard.Pcb board is fishbone, there are a main shaft in its central authorities, the diverse location of main shaft both sides is outwards parallel extends support, the groove of fishbone is had in the side that panel contacts with backboard, nested with the pcb board of fishbone, the main shaft of pcb board and support there is LED 3 respectively, has supporting lampshade 4 above each LED, panel has the through hole corresponding with LED.

Pcb board comprises main control module, power management module, sound wake module, LED drive module and the LED (as Fig. 3) of band bluetooth.

Main control module adopts the BLE control chip of band bluetooth or similar concrete logical circuit, not only low in energy consumption, and process data are fast, and various hardware interface is complete.Wherein, the battery detecting mouth that AD mouth charges as battery, I2C interface is connected with LED drive IC, and GPIO mouth can as waking detection up, and charging detects (as Fig. 4).

Whole subject core adopts the DA14580 chip of band bluetooth, both solve bluetooth communication, can peripheral circuit be driven again, not only can save corresponding cost, overall design also can make overall volume less, this is the main feature distinguishing existing society product.I2C interface is connected with LED drive IC, carries out light on and off to LED, and light modulation manages, and compare the scan mode in society, independent lighting pattern, has better Consumer's Experience.The ad interface of 10bit, connects charging inlet (AD_BAT), can read cell voltage accurately.Common I/O port is connected can wakes IC up with MIC mouth (power_start).

Power module comprises charging module and discharge module.Charging adopts current main flow QI wireless charging, and coordinate Charge Management IC to protect battery charging, extend battery, current QI wireless charging adopts the module (as Fig. 5) of standard on the market.

Power management section comprises an a LDO and Charge Management IC (APL3202), and wherein the effect of LDO is depressured to 3.0v, current master control IC operating voltage (2v-3.6v), so will pass through LDO step-down.When Charge Management IC (APL3202) is mainly charged by 5V, better can protect the circuit of battery, can battery over-discharge be protected, overvoltage, overcharge, excess temperature, can the safety of available protecting battery life and user.The AD mouth of AD_BAT mouth connection master control IC is convenient to the charge capacity of real-time detection battery.CHAR_STAT mouth mainly notifies that master control IC is current whether in charging.

LED drive module comprises 1 LEDs drive IC (SN3731I428E), and this IC primary responsibility drives matrix L ED, is scanned by the LED of complexity, becomes simple I2C communication command (as Fig. 6 and Fig. 7).

LED drives the light on and off display of main management LED matrix, simultaneously can 255 grades of light modulations of each lamp of driving LED.

A whole set of sound wake module comprises a MIC Receiver (-30db), a LMV321 signal operation amplifier, a mono-Schmidt's inverter (as Fig. 8) of SN74AHC1G14DBVR.The signal of MIC head collection is very faint, so the signal that will be collected by MIC through LMV321 operational amplifier amplifies out (adopting 30 times of amplifications at present) with certain multiple, when amplifying signal out after, because digital IC is None-identified simulating signal, so signal conversion correcting process will be carried out through SN74AHC1G14DBVR, after process, master control IC just can well be other.Because equipment has set pin awakening mode before sleeping again, as long as so receive the signal that MIC transmits, IC will be waken up.After equipment need not enter sleep state for a long time, as long as pick up guitar, fluctuation string (volume higher than 70 points) equipment will wake up.

Guitar fingerboard fishbone unitary design, compact conformation, replace conventional wooden structural and complete by injection moulding, the process of fingerboard surface coating more increases the aesthetic feeling of guitar.LED hole stand alone type lampshade structure provides sufficient installing space for LED, and spotlight effect is better, after LED is lighted, make the light of " one one " more beautiful through end face.

The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
