The alarm of Xiao Shouing roughly can be divided into two classes in the market, a class be volume big, give great volume; Another kind of is that volume is little, volume is little.The former designs at company, businessman, and latter's design is to use at general domestic consumer, and it emphasizes easy installation, hidden characteristics.But the latter always has the sense of deficiency on volume, and this is because traditional alarm (as shown in Figure 1) is to utilize the interaction of vibrating membrane 1, voice coil loudspeaker voice coil 2, iron core 3 to sound; Its principle is that voice coil loudspeaker voice coil 2 is supplied with an audio voltage to produce electric current, under unshakable in one's determination 3 fixed magnetic field, changing audio voltage changes the electric current by voice coil loudspeaker voice coil 2, make voice coil loudspeaker voice coil 2 be subjected in various degree magneticaction, because voice coil loudspeaker voice coil 2 is fixed on the vibrating membrane 1, voice coil loudspeaker voice coil 2 has also produced vibrating membrane 1 up-down vibration in the time of stressed and has sounded.This traditional vocal structure, the sound cover structure is huge, when sound is passed to the outside by vibrating membrane, must cause a large amount of volume losses through sound clamshell, the shell wall of longer distance.Therefore, as need the output of louder volume, just need sizable volume, to hold iron core, vibrating membrane and the voice coil loudspeaker voice coil that produces strong magnetic force, because of the energy while that increases voice output also causes power consumption to heighten.Therefore, this structure obviously can not provide louder volume, low power consumption, volume is little and easy alarm is installed, and can't satisfy the user demand of ensuring public security at home.
Therefore, adopt piezoelectric type pottery sounding sheet 20 ceramic loudspeakers, just arise at the historic moment, more traditional loudspeaker, its volume is less, and especially low power consumption characteristic makes drives easy, and its volume is higher, very meets to save demand at home from damage.Traditional ceramic sounding sheet 20 has two kinds of fixed forms, is respectively circumference fixation and fulcrum cementation method (shown in Fig. 2-1 and Fig. 2-2).The circumference fixation, it helps to widen frequency response, and fulcrum cementation rule can strengthen the resonance sound press.But these two kinds of cementation methods when improving more than the volume to 100 decibel, then need to strengthen ceramic sounding sheet 20 diameters, and need higher driving power, and the power consumption electric current increases relatively; And which kind of method no matter, it needs many one cementation formalities, can cause the sound press deficiency as cementation when not good, causes difficult quality to grasp.What is more, pottery sounding sheet 20 can be because cementation limits its distortion, if desire strengthens volume output, need to improve promotion voltage, pottery sounding sheet promptly produces local flexible deformation, cause ceramic sounding sheet 20 ceramic plane to break or come off easily, cause the reliability of products deficiency, have a strong impact on product serviceable life.Therefore, this technology can not provide simultaneously obviously that volume is little, louder volume, low power consumption, quality are steady, assembling demand easily and cheaply.
Summary of the invention
The utility model fundamental purpose is to provide a kind of louder volume, and especially low power consumption, the not fragile and easy small size pottery of installation alarm speaker are to satisfy the user demand of ensuring public security at home.
The utility model comprises sounding component and sound clamshell, pottery sounding sheet is arranged in the housing of sounding component, to carry on the back when lid is installed on the housing adopts hot pressing mode to seal, an and small vibration sounding space between control housing and the ceramic sounding sheet, pottery sounding sheet makes ceramic sounding sheet at small vibration sounding space internal vibration sounding by the alerting signal driven, sound is sent by the sound mouth of housing, the reflection of blocking through sound clamshell and housing, form the resonant structure of secondary reflection, sound is radiate by sound clamshell opening at last.
