Embodiment one：
The present embodiment provides a kind of projected keyboard with bluetooth conversation function, as shown in figure 1, including：
Bluetooth module 30 and NFC module 40, NFC module 40 are used to match and build with outside bluetooth equipment with bluetooth module 30
Vertical audio signal transmission passage；
The alarm module 50 being connected with NFC module 40, when NFC module 40 is disconnected with outside bluetooth equipment, triggering
Alarm module 50 works；
Control module 10, the control bluetooth module 30 of control module 10 and NFC module 40 are matched with outside bluetooth equipment；
Audio power amplifying circuit is provided with the audio playing module 60 being connected with control module 10, audio playing module 60
610, for amplifying audio signal；
The audio being connected with control module 10 includes module 70, for converting audio signals into electric signal；
And, the power module 20 of working power is provided for projected keyboard.During specific works, outside bluetooth equipment is opened blue
Bluetooth equipment near tooth searching functions, when close contact is to audio amplifier projected keyboard, outside bluetooth equipment can be directly from NFC moulds
The chip address of bluetooth module 30 is got in block 40, and is transferred in the bluetooth module of outside bluetooth equipment into Bluetooth pairing
State, now wakes up bluetooth module 30, realizes the final pairing of bluetooth, then set up audio signal transmission channel transfer sound simultaneously
Frequency signal, when outside bluetooth equipment is away from bluetooth conversation function projected keyboard, pairing can be disconnected automatically, at this moment, triggering report
Alert module 50 is the regular flicker of LED, points out bluetooth conversation function of the outside bluetooth equipment in projected keyboard too far,
So that bluetooth conversation function can not carry out audio signal transmission with outside bluetooth equipment again, user is reminded to note shortening outside indigo plant
The distance of tooth equipment and bluetooth conversation function.Audio, which includes module 70, has the function of converting audio signals into electric signal, uses
In including and transmitting the audio signal that user sends, the alternating transmission of audio signal is carried out with outside bluetooth equipment such as mobile phone.
In the present embodiment, audio includes module 70 for extension type microphone 710, and extension type microphone 710 is linear soft
Material, wound form is in projected keyboard.Extension type microphone 710 is provided with radio reception sponge.It can so avoid using ring
Radio reception is unclear when border is more noisy, it is also possible that user need not speak against projected keyboard, improves Consumer's Experience.
In the present embodiment, alarm module 50 is LED, when NFC module 40 is disconnected with outside bluetooth equipment,
The regular flicker of LED.
In the present embodiment, LED is located on the line style flexible pipe with moulding ability, and flexible pipe is in projected keyboard.By
In with moulding ability, user can arbitrarily be twisted into desired form, change the illumination direction of LED, so that LED is not
Only there is alarm function, Consumer's Experience can also be strengthened in night floor light.
In the present embodiment, audio playing module 60 includes boombox.Loudspeaker is provided with catch net, and in protection
Radio reception sponge is provided with the net so that tonequality is more perfect during playing audio signal.
In the present embodiment, the generating laser of projected keyboard is turnably assembled with projected keyboard, and generating laser can

In the present embodiment, projected keyboard bottom is equipped with folding projector panel.
In the present embodiment, it is detachable in projected keyboard to be equipped with support, support and panel-mounted, for supporting surface
Plate.When specifically used, foldable projector panel is spread out, adjust the angle of generating laser so that the projected keyboard on panel
It is high-visible, so that even if being handled official business on rough desktop, use that can be good.When user needs to adjust projection
The height of panel, which is typewrited adapting to both hands, causes typewriting not for a long time, can pull down detachable bracket, frame in projector panel lower end,
Increase projector panel with placing the distance of desktop, and support, using two sections of sleeve type structures, sleeve pipe overlapping uses nut knot
The movable pressing of structure, thus can arbitrarily scale length to adjust the height of support.
In the present embodiment, power module 20 is rechargeable type lithium battery.
So so that can also operationally enjoy music, and it can be automatically reminded to match with outside bluetooth equipment
Situation, is assembled with folding projector panel and is suitable for various placement desktops, strengthen Consumer's Experience.
Embodiment two：
The difference of the present embodiment and above-described embodiment is：In the present embodiment, the alarm module 50 is the audio
Playing module, when the NFC module 40 is disconnected with outside bluetooth equipment, the audio playing module plays default sound
Frequently, when outside bluetooth equipment is away from bluetooth conversation function keyboard, pairing can be disconnected automatically, at this moment, trigger alarm module 50
I.e. audio playing module plays preset audio, can be the quarter-bell mixed up in advance, points out outside bluetooth equipment apart from projected keyboard
On bluetooth conversation function too far so that bluetooth conversation function can not again with outside bluetooth equipment carry out audio signal transmission, carry
Awake user notes shortening the distance of outside bluetooth equipment and bluetooth conversation function.
Embodiment three：
The difference of the present embodiment and above-described embodiment is：Audio playing module 60 includes external earphone.External earphone can
To avoid bothering other people during playing audio signal so that the utility model is adapted to more use occasions.
Example IV：
The difference of the present embodiment and above-described embodiment is：Existing earphone typically all has microphone and audio player
Function, circumscription socket can be set to insert above-mentioned earphone in control module 10 and come that alternate audio includes module 70 and audio is broadcast
Amplification module 60.
