The small sound / vibration combined type alarm shown in FIG. 16 has a flat cylindrical buzzer body (an electroacoustic element) on a disk-shaped leaf spring 3 fixed so as to cover one opening side of a cylindrical case 2. ) Is mounted and fixed, and a ringer diaphragm 8 whose electromagnetic coil 9 is fixed on the inner surface side is placed on the other opening side of the cylindrical case 2 and fixed. That is,

いる。The electromagnetic coil 9 is provided on the peripheral wall 4a of the lower yoke 4.
Since it is placed in the magnetic field (magnetic path) in the gap between the upper coil and the upper yoke 6, when an alternating current of a high frequency (2500 Hz to 3500 Hz) is externally applied to a pair of lead wires 9a of the electromagnetic coil 9, the alternating electromagnetic Since the electromagnetic coil 9 oscillates with a small amplitude in the axial direction in synchronization with the alternating cycle due to the generation of the force, the ringer diaphragm 8 having a high natural frequency has its natural frequency (several kHz).
Resonates at z). The natural frequency f 0 of the ringer diaphragm 8 (the buzzer itself) and the resonance frequency f of the resonance chamber S
With v (> f 0 ), the frequency band is expanded due to the Helmholtz resonance effect, and the sound pressure is increased. On the other hand, the electromagnetic coil 9
Is connected to a low frequency (100 Hz to 200 Hz).
When an alternating current of (Hz) flows, the electromagnetic coil 9 oscillates at a small amplitude in the axial direction in synchronization with the alternating cycle due to the generation of the alternating electromagnetic force, and the lower yoke 4, the magnet 5, and the upper yoke 6 react as the reaction. Since the magnetic path forming body also vibrates slightly,
The leaf spring 3 having a low natural frequency is excited. For this reason, since the leaf spring 3 resonates at a large amplitude having a low natural frequency, the entire case 2 vibrates at a perceptible low frequency amplitude. The external form of the combined sound and vibration type alarm having such a structure is a small-diameter flat cylinder having a diameter of about 15 mm and a height of about 5 mm.

れる。That is, as a so-called back plate for mounting the electroacoustic element, an annular plate spring 3 made of stainless steel having a central hole 3a into which the bottom of the lower yoke 4 is fitted is used. The diameter of the leaf spring 3 is
Since the diameter is as small as about 14 mm, the natural frequency of the leaf spring 3 in the central axis direction is a high frequency, like a small drum. Although a low frequency of about 100 Hz is preferable as the frequency of the rigid body vibration that can be well sensed by the human body, the vibration itself is still sensed by the above-mentioned alarm because of its too high frequency because of the familiarity with the vibration. hard. Here, in order to easily detect the vibration, it is necessary to lower the vibration frequency and increase the vibration energy, and it is also important to increase the amplitude and the weight of the mounted object. If the lightening portion is increased in the plate portion of the leaf spring 3, the natural frequency of the flexural vibration can be reduced even with the small-diameter leaf spring 3, but if the lightening portion is increased inexorably, the mounted object such as the lower yoke 4 will be reduced. The support strength to support falls, and the spring property is also impaired.

れて成ることを特徴とする。In order to solve the above-mentioned problems, a first means of the present invention is that a leaf spring used in a vibration type alarm is a substantially annular strip surrounding a central hole, The strip is characterized in that a plurality of substantially spiral plate separation holes are formed.

できるから、支持強度を高めることができる。When a leaf spring having such a shape is used, the natural frequency of the flexural vibration of the leaf spring is reduced to 100 Hz by a thinned portion formed by a plurality of plate separation holes, even though the leaf spring has a small diameter.
It can be reduced to a low frequency. In addition, since a plurality of substantially spiral plate-shaped separation holes are formed, the remaining inner peripheral plate material is connected to the outer peripheral plate through a plurality of substantially spiral middle plate members. For this reason, since the electroacoustic element can be distributed and supported through the plurality of substantially spiral-shaped middle plate portions, the supporting strength can be increased.

がら、振動を感知し易い振動式報知器を実現できる。Further, the inner peripheral side plate portion can easily be extended in the direction of the central axis with respect to the outer peripheral side plate portion, and the amount of deflection (amplitude) can be optimized without deteriorating the spring property. Therefore, since a large amplitude can be obtained at a low frequency, it is possible to realize a vibration-type alarm device which is small in size and easy to detect vibration.

ンスになり易い。When the substantially spiral plate-shaped separation hole is elongated and the circling angle is increased, the spring constant is reduced and the amplitude is increased, but conversely, the hollow portion is increased and the support strength is reduced. In addition, when the number of the substantially spiral plate-shaped separation holes increases, if the band width of the substantially annular strip is narrow, the plate-shaped separation holes are too crowded, and the length of the plate-shaped separation holes (circular angle). Cannot be increased, so that the deflection amplitude cannot be increased. In addition, when the number of the plate separation holes is one or two, the vibration direction is shifted from the center axis, and a two-dimensional component is mixed in the bending motion, so that the unbalance tends to occur.

き、より一層、剛体振動が感知し易くなる。Therefore, it is preferable that the plurality of substantially spiral plate-like separation holes are formed of three lines and formed in a three-row pattern. In the triangular pattern, the orbital angle of each board separating hole is less than one orbit (360 °). Desirably, 180 ° to 240 ° is preferable. Increasing the rotation angle can lower the natural frequency. According to the leaf spring having the three-sided pattern separation hole, the support strength can be maintained, the spring constant can be optimized, and the axial vibration direction can be uniformed, and the rigid body vibration can be more easily detected. .

When the notch is formed at the edge of the central hole in the peripheral plate, the inner plate that is too wide compared to the other is cut off without making a hole, so the supporting strength is increased. Contributes to the maintenance of and the optimization of the spring constant.

部品点数を削減できる。An electroacoustic element is mounted and fixed on the above-mentioned leaf spring fixed on one opening side of the cylindrical case, and a ringer diaphragm to which an electromagnetic coil of the electroacoustic element is fixed is mounted on the other side of the case. In the sound and vibration combined type alarm that is fixed over the opening side, a large stress is applied to the adhesion between the electromagnetic coil and the ringer diaphragm in the reaction of the electroacoustic device on the leaf spring that vibrates at a low frequency with a large amplitude. I do. For this reason, in the present invention, the electromagnetic coil and the ringer diaphragm are integrally formed with a resin layer connected to the electromagnetic coil through a resin flow hole formed in the ringer diaphragm. Compared to the case where the ringer diaphragm and the electromagnetic coil are fixed to each other with an adhesive, there is no peeling of the adhesive, the reliability can be improved, and the number of parts to be assembled can be reduced.

It is caulked and fixed to the surrounding area. The resonance chamber is provided to increase the sound pressure of the ringer diaphragm due to the resonance effect. However, the other opening side of the case is swaged to the periphery of the cover plate to fix the cover plate and the ringer diaphragm. Can be achieved simultaneously.

A yoke, a magnet fixed to the bottom surface of the first yoke, and a second yoke fixed on the magnet, and the peripheral wall of the first yoke has a substantially annular shape. The weight body is externally fitted.

振動併用型報知器を実現できる。A magnetic path forming body composed of a first yoke, a magnet and a second yoke is mounted on the leaf spring. In addition to this, a substantially annular weight body made of a heavy metal such as tungsten is used. Is increased, the vibration inertia force increases, and the amount of deflection (amplitude) of the leaf spring can be increased. The electromagnetic coil is located in the gap between the inner peripheral surface of the peripheral wall of the first yoke and the outer peripheral surface of the second yoke, but the outer peripheral surface of the peripheral wall of the first yoke faces the inner surface of the case. Since it is a part, a substantially annular weight may be worn. Instead of increasing the thickness of the peripheral wall of the first yoke itself, a structure in which a substantially annular weight having a large specific gravity is fitted outside can increase the amplitude of the leaf spring more efficiently. Because the mass of the vibrator is large and a large amplitude can be obtained, the sound
Vibration combined type alarm can be realized.

However, since the leaf spring vibrates violently due to the bending deformation, when both are fixed with an adhesive, problems such as peeling of the adhesive are caused. There is a fear of. Therefore, in the present invention, the first yoke and the leaf spring are fixed by laser welding. The yoke is made of pure iron and the leaf spring is made of stainless steel (for example, SUS30
Even in the case of 4), the fixing reliability is high.

ス自体の堅牢化に寄与する。When the amplitude of the leaf spring increases, an extra space for the leaf spring to freely vibrate must be secured in the case. In view of this, the inner peripheral flange in the present invention is not limited to simply placing a leaf spring, but is formed as a flange having at least two steps of reduced diameter. When the end portion of the case is at least a two-step reduced-diameter flange portion, the thickness of the extra space is at least twice the thickness of the case. Therefore, there is more room to vibrate the leaf spring with a large amplitude. In addition, it contributes to the rigidity of the case itself.

When a high-frequency alternating current flows from the alarm driving circuit on the substrate 90 to the electromagnetic coil 45 via the relay terminal pin 85 and the lead wire 45a, the electromagnetic coil 45 itself is synchronized with the alternating cycle due to the generation of the alternating electromagnetic force. Vibrates at a minute amplitude in the direction of the central axis, and the ringer diaphragm 46 resonates at its natural frequency (2800 to 3000 Hz). Then, the natural frequency f 0 of the ringer diaphragm 46 and the resonance frequency f v (> f 0 ) of the resonance chamber S expand the frequency band due to the Helmholtz resonance effect, thereby increasing the sound pressure. It can be used for ringing sounds of mobile phones and pagers.

As a result, the magnetic path forming body composed of the lower yoke 42, the magnet 43, and the upper yoke 44 also vibrates slightly as a recoil. As a result, the leaf spring 30 has a low frequency (11
(About 0 Hz), and the entire case 20 vibrates at a perceptible amplitude.

１０を実現できる。Since the substantially annular band plate 32 of the leaf spring 30 has a lightened portion formed by three strips of plate separation holes 33, 34, and 35, the inner peripheral side plate portion 36 is formed. The natural frequency of the bending vibration (in the direction of the central axis O) is set to a low frequency of about 110 Hz. In addition, the board separating holes 33, 34,
35 is formed in a substantially spiral shape, the lower yoke 42
The inner peripheral board portion 36 as a movable portion to which is fixed is connected to an outer peripheral board portion 37 as a fixed portion via three substantially spiral middle plate portions 38. For this reason, since the three electroacoustic elements 40 can be distributed and supported in a suspended state via the three spirally formed middle plate portions 38, the supporting strength can be increased. Furthermore, the tail 33 of the board separation holes 33, 34, 35
Since the twisting action of the substantially spiral middle plate portion 38 itself is superimposed on the inner connection portion N with the outer connection portion M on the b, 34b, 35b side as a base end, the inner plate portion 36 is formed on the outer periphery. It is easy to feed out the center axis O with respect to the side plate base portion 37. Not only the bending deformation of the middle plate portion 38 but also the torsion spring property is utilized, so that the spring constant is not greatly reduced.
A suitable amount of deflection (amplitude) can be obtained. Accordingly, since a large amplitude can be obtained at a low frequency, it is possible to realize the combined sound / vibration type alarm 10 that generates a vibration that is easily sensed in a small configuration.

Reference numerals 4 and 35 are formed in a three-row pattern arrangement. In this three-row pattern, the orbital angle of each of the board separating holes 33, 34 and 35 is approximately half an orbit (190 °). Orbit angle is 24
When the angle is 0 ° or more, the band width of the substantially annular band plate 32 is divided by a maximum of three strip separation holes 33, 34, and 35, and the remaining strip portion of the four stripes is narrowly lost. The support strength deteriorates.
A leaf spring formed in a two-row pattern from two substantially spiral strip-shaped plate separation holes is also conceivable, but the vibration direction is easily shifted from the axial line, and two-dimensional vibration is likely to occur. A leaf spring using four or more plate separation holes is also conceivable, but if you secure the length of the middle plate part and take advantage of the torsion spring property,
Since there is a portion where the number of divisions of the band width of the annular band plate 32 is 4 or more, the supporting strength is deteriorated. Therefore, according to the leaf spring 30 having the triangular plate-shaped separation holes, the support strength can be maintained, the spring constant can be optimized, and the on-axis vibration direction can be uniformed.

く、連結強度を高めてある。In the region of the outer connecting portion M and the inner connecting portion N, it is necessary to secure a relatively large area in order to increase the connecting strength as a support end of the cantilever. In addition, when the middle plate portion 38 is connected to the outer peripheral side connection portion M or the inner peripheral side connection portion N at a spiral curve portion shown by a two-dot chain line in FIG. 5, a stress greater than the proof stress acts on the connection portion. Therefore, plastic deformation or fracture is likely to occur beyond the yield point. Therefore, in this example, such a spiral curve portion is formed as a straight line portion L, so that it is difficult to twist and the connection strength is increased.

３６の円周に沿った部分の撓みを平等化している。Since the inner peripheral side connecting portion N is too wide as compared with the others, the inner peripheral side plate portion 36 is less likely to bend in the circumferential direction of the inner peripheral side plate portion 36, and twist deformation tends to spread to the hole edge side. However, in this example, the notch 36a is formed at the hole edge of the central hole 31 instead of forming the hole, so that it is difficult to spread the twist to the hole edge side while securing the supporting strength. The bending of the portion along the circumference of the peripheral side plate portion 36 is equalized.
