Description

A kind of baby monitor and perambulator can customize vocal music

Technical field

The utility model is related to infant monitoring apparatus field, more specifically, it relates to which a kind of can customize vocal music Baby monitor and perambulator.

Background technology

Currently marketed baby monitor product is generally used in fixed lullaby direct burning to music IC, when Fixed lullaby can only be played in music IC when baby cry to fool baby.Actually roars of laughter baby's most effective way is to come from The sound of mother, existing baby monitor user can not voluntarily record or self-defined sound or music, this makes existing There are clearly disadvantageous in terms of fooling baby for baby monitor product.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of recording of band and playing function Baby monitor so that baby monitor fool the effect of baby is more preferable, experience more preferably.

To achieve the above object, the utility model provides following technical solution：

A kind of baby monitor can customize vocal music, including：

Microcontroller, including the sound identification module of vagitus for identification；

Sound acquisition module is electrically connected with microcontroller, for acquiring sound and exports audio signal；

Memory module, for storing audio data；

Human-computer interaction module is electrically connected with microcontroller, for generating operational order；

Sound broadcasting module is electrically connected with control module, for playing sound.

Using the above scheme, mother can into monitor advance typing roars of laughter baby sound, when monitor identifies baby It is automatic to play the sound recorded when vagitus makes a noise, it allows baby to generate the feeling of " mother " at one's side, promotes the effect of roars of laughter baby.

Preferably：It further include the wireless module being electrically connected with microcontroller.

Using the above scheme, by audio transmission module, which can connect with external equipment, receive external equipment The audio signal of output, so as to realize that User Defined, voluntarily the song of baby is fooled in switching, promotes the effect of roars of laughter baby, Improve hommization degree.

Preferably：The sound acquisition module includes sound pick-up and A/D conversion circuits, the signal of the sound pick-up Output end connects the input terminal of A/D conversion circuits, and the output end of the A/D conversion circuits connects microcontroller.

Preferably：The sound acquisition module further includes filtering Dolby circuit, the filtering Dolby circuit connection Between sound pick-up and A/D conversion circuits.

Using the above scheme, the audio signal that filtering Dolby circuit can export sound pick-up is filtered noise reduction, improves The degree of purity and clarity of voice acquisition.

Preferably：The memory module is FLASH memory.

Preferably：The human-computer interaction module is button or touch screen.

Preferably：The sound broadcasting module includes speech chip and loudspeaker, the speech chip and microcontroller Device connects, and the loudspeaker connect speech chip.

Using the above scheme, the sound that can make monitor output high-fidelity, high-quality, more really restores voice.

Preferably：The wireless module is RF modules.

Preferably：The sound pick-up is directing sound pick-up.

Using the above scheme, compared to common sound pick-up, sound pick-up is directed toward to the sound collection within the scope of effective angle It wants sensitiveer compared to except effective angle, by the direction of monitor, baby is made to be in its effective pickup angle, The sound acquired in the angle can reduce ambient noise to acquiring vagitus in this way than the sound bigger that other angles acquire Caused by interfere, improve monitor identification baby cry sound accuracy.

The purpose of this utility model also resides in a kind of perambulator, using the perambulator fool the effect of baby is more preferable, experience more It is good.

A kind of perambulator, including vehicle body are equipped with the above-mentioned baby monitor that can customize vocal music on the vehicle body.

Compared with prior art, the utility model has the advantages that：The monitor, mother can in advance typing roars of laughter baby sound Sound, the monitor during the work time, are acquired the sound in ambient enviroment and identify whether the crying for having baby, work as baby When youngster sends out crying, monitor plays out the sound for the roars of laughter baby that mother prerecords by loudspeaker.In this way, even mother is not Baby at one's side, when baby cry, the monitor can also function well as roars of laughter baby effect, serve as the angle of " interim mother " Color.The monitor is the perambulator equipped with the monitor, not only fools the effect of baby good, but also can also alleviate mother with baby's Pressure.

Specific implementation mode

Embodiment one：

Referring to Fig.1, a kind of baby monitor can customize vocal music, including sound acquisition module, microcontroller, button mould Block, memory module and sound broadcasting module, sound acquisition module, key-press module, memory module and sound broadcasting module with Microcontroller is electrically connected.

In the present embodiment, microcontroller includes sound identification module, and sound identification module is built-in recognizer；Sound Acquisition module includes sound pick-up, filtering Dolby circuit and A/D conversion circuits, wherein the output end connection filtering noise reduction electricity of sound pick-up The input terminal on road, filters the input terminal of the output end connection A/D conversion circuits of Dolby circuit, and the output end of A/D conversion circuits connects The audio input end for connecing microprocessor, to promote the effect of sound collection, which uses directing sound pick-up；Memory module For FLASH memory；Key-press module connects the I/O interfaces of microprocessor；Sound broadcasting module includes speech chip and loudspeaker（ Loudspeaker can be only used）, the audio output of the input terminal connection microprocessor of speech chip, the output end connection of speech chip Loudspeaker.

The monitor presses " recording " button back eye monitor and enters recording before use, mother can carry out recording operation State, mother need the sound for sending out roars of laughter baby to complete recording at this time, and the audio data under recording is stored in FLASH memory.

Monitor can then be begun to use, which can be placed on perambulator, infanette, bassinet or baby In room.During the work time, sound pick-up is acquired to the sound in ambient enviroment and exports audio signal for the monitor, when When baby sends out crying, sound is collected by sound pick-up, and filtering Dolby circuit is filtered to drop the clutter in audio signal The analog audio signal of filtered noise reduction is converted to digital audio and video signals, digital audio by low environment noise, A/D conversion circuits Signal is transferred to microprocessor, and microprocessor is identified audio signal to determine whether the crying of baby, is identified as After work(, audio data is simultaneously sent to voice playing module by audio data in microcomputer reads FLASH memory, and voice is broadcast Audio data is reduced into sound by amplification module, and loudspeaker can play out the sound for the roars of laughter baby that mother prerecords at this time.In this way, Even mother not baby at one's side, when baby cry, the monitor can also function well as roars of laughter baby effect, serve as The role of " interim mother ".

The monitor not only fools the effect of baby good, but also can also alleviate pressure of the mother with baby.

Embodiment two：
