Abstract
The utility model provides a micro electromagnetic music instrument which is normally called a miniature electric horn. The utility model is characterized in that a housing of the micro electromagnetic music instrument is a closed structure, and the electronic elements of a cover, a casing, a bracket, spring pieces are tightened by punching and extruding and connected by rivets. A suite of field coil of the utility model which can continuously work for a minute, has a high electroacoustic conversion efficiency and a light weight can generate an output rating of 3.7 tile with the battery voltage of 1.5V. The utility model with an outer diameter of only 40 millimetres, weight of 35 grams, and loudness of sound of 100 decibels can be used for daily-use industrial goods as a sound-producing device in an alarm, the acoustic horn of a rickshaw, an electrical bell in a house and a high-grade toy.
Description
The utility model relates to calling device, belongs to the electromagnetism Chinese percussion instrument that shakes especially, is commonly called as electric horn.
Electric horn on the market all is to be used for automobile, motorcycle, and this electric horn volume is big, and heaviness adopts battery power, and power consumption is big, and high price is expensive, and range of application is narrow.Up to now also do not have a kind of miniature electric horn of in manufactured goods, using, make it, rickshaw loudspeaker, family expenses electric bell, the sound-producing device of senior toy as alarm.
The purpose of this utility model provides a kind of micro electromagnetic Chinese percussion instrument that shakes, and makes it have higher electro-acoustic conversion efficiency and wide wide usable range.
The utility model is achieved in that it comprises lid, iron core, sharpens magnetic coil, the metallic membrane of band contact, the spring leaf of band contact, housing, support, button, power supply and lc circuit.It is characterized in that the end limit covered wraps in the inside with the top crimp of housing, and press by impact extrusion and to make lid and housing become to seal to be connected.The metallic membrane of band contact is positioned at the below of lid, and it and housing press solidly tightly together by impact extrusion between the lead-in wire of electric capacity.Being positioned at the housing bottom top has support, and support and housing are connected by rivet between the spring leaf of band contact.Support and iron core tighten up mutually by the impact extrusion pressure between the whetstone magnetic coil.
The capacity of the electric capacity in the lc circuit is 3-5MF/25V, the line of sharpening magnetic coil directly is 0,35～0,45 millimeters of φ, the number of turns is a 230-240 circle, and this coil is 1, during the 5VDC power supply, by 2, the 5A electric current still can keep output power to reach maximum electro-acoustic conversion efficiency for 3,7 watts in one minute.
The utility model is connected with rivet owing to adopting impact extrusion to press solidly tightly, and shell becomes enclosed construction, and shockproof waterproof is light and handy, clear loud and clear, applied range.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a lc circuit synoptic diagram of the present utility model.
The utility model is described in further detail below with reference to drawings and Examples.
With reference to Fig. 1 and 2, lid 1,2 of inertia plates beat oscillating action.Iron core 3 and coil 4 constitute one and sharpen magnetic magnetic field, and the line of present embodiment coil 4 directly is 0,35～0,45 millimeter, and the number of turns is 230～240 circles.Band contact metal diaphragm 5 and band touch spring sheet 6 are used for sounding.Housing 7 and lid 1, between the lead-in wire of metallic membrane 5 electric capacity 8, and support 13 and iron core 3, adopt impact extrusion to press solidly tightly between the coil 4.Support 13 and housing 7 adopt rivet 10 to connect between the band touch spring sheet 6 and between inertia plate 2 and the band touch spring sheet 6.Insulation sleeve 9, insulation spacer 11.Set screw 12 is used for regulating the gap between iron core and the inertia plate, to regulate oscillation starting points and volume.Button 14, power supply 15, present embodiment adopt that voltage is 1, the 5V battery.
When pressing the button 14, by logical lc circuit, produce and sharpen magnetic field, iron core 3 attracts spring leaf 6 downward, and two contacts disengage, and magnetic field disappears, and its touch spring sheet 6 nationalitys self bounce resets, and drives inertia plate 2 and beats band contact diaphragm 5 with certain speed, makes it sounding.Because two contacts contact once more, and button still according to, circuit continues to connect, sounding carries out repeatedly, stops to press until button 14, sounding stops.
Only 40 millimeters of present embodiment external diameters, highly about 15 centimetres.The capacity of capacitor C is 3-5MF/25V, and a cover is sharpened magnetic magnetic field and produced 3,7 watts of output powers 1, under the effect of 5V cell voltage, can continuous working one minute, do not lose its high efficiency electroacoustic conversion ratio.About 100 decibels of sound.
