Referring to FIG. 1, the horn 100 includes an alarm pole 110, a horn switch 120, an alarm switch 120, A power supply unit 140, and a verbose output unit 150. [

The iron core 110 has a coil wound around a first portion and a second portion. At this time, when the coil is wound on the iron core 110, the first portion and the second portion can be wound more than the first portion. For example, in the first part, the coil is wound on the iron core 150 times, and the first part and the second part are wound on the iron core 250 times.

The horn switch 120 switches to supply power to the first part of the coil in accordance with the operation of the driver, in order to output a beep sound.

When the alarm switch 130 receives a burglar alarm signal from the burglar alarm device, the first and second parts are switched to be supplied with power to output an alarm sound.

The power supply unit 140 supplies power to the first part of the coil when the horn switch 120 is turned on and the first part of the coil and the second part of the coil when the alarm switch 130 is turned on. The power is supplied to the part.

The oblique output unit 150 generates and outputs a beep sound or a beep sound according to the magnetic force generated by the electromagnet action of the iron core 110. At this time, the magnetic force generated by the first portion of the coil can be said to be more than the magnetic force generated by the first portion and the second portion of the coil. That is, the first portion of the coil has a small inductance (resistance) value because the number of times the coil is wound on the iron core 110 is smaller than the number of turns of the first portion and the second portion, The magnetic force is greater than the current flowing in the portion.

Here, the tilting output unit 150 includes a diaphragm 152 disposed on the upper side of the iron core 110 as shown in FIG. 2; A resonance plate (154) disposed on the upper side of the diaphragm; An armature 156 inserted and coupled to the diaphragm and the resonator plate; And a switching unit 158 for switching power supply to the first part or the first part and the second part according to the operation of the armature by the magnetic force.

The diaphragm 152 interlocks with the up and down movement of the armature 156 and reciprocates vertically. The diaphragm may include a first central portion (not shown) and a first peripheral portion (not shown) integrally formed on the outer side of the first central portion. The first center portion is formed in a substantially flat plate shape, and a first insertion hole (not shown) is formed at the center thereof so that the armature 156 is inserted and coupled. The first peripheral portion can be seated on the flange of the body at the bottom edge of the rim.

The resonance plate 154 is disposed on the upper side of the diaphragm 152 and resonates the vibration of the diaphragm 152 to generate a sound or alarm sound. The resonance plate 154 may include a second center portion (not shown) and a second peripheral portion (not shown) integrally formed on the outer side of the second center portion. The second center portion is formed in a substantially flat plate shape, and a second insertion hole (not shown) is formed at the center thereof so that the armature 156 is inserted and coupled. The diameter of the second insertion hole may be the same as the diameter of the first insertion hole. The second peripheral portion may be formed to be convex upward to have a predetermined radius of curvature extending outside the first central portion, and the rim may be formed to have a predetermined radius of curvature in the upward direction.

The armature 156 may be formed of a magnetic material such as a metal material so as to be raised and / or lowered by a magnetic force generated in the iron core 110. The armature 156 is integrally formed on the bottom surface of the body portion and is disposed on the upper side of the bobbin (not shown) and has a substantially cylindrical shape. The armature 156 is integrally formed on the upper surface of the bobbin (Not shown) integrally formed on the upper surface of the body portion and coupled to the diaphragm 152 and the resonance plate 154.

The iron core 110 may be formed of a magnetic material, for example, a metal material, to apply a magnetic force to the armature 156 by a magnetic force applied from a coil. The iron core 110 includes an upper pole disposed below the armature 156 and a lower pole disposed below the upper pole. The upper pole is disposed below the armature 156 and is axially movably inserted under the hollow hole of the bobbin. The upper pole may be formed in a cylindrical shape having an outer diameter corresponding to the diameter of the hollow hole. A flange having a diameter larger than a diameter of the through hole is formed in an upper portion of the lower pole so as to be stably formed on the upper portion of the lower pole, Lt; / RTI >

2 is a cross-sectional view showing the structure of a horn according to an embodiment of the present invention.

2, the switching unit 158 includes a stand 162 connected to the power supply unit 140; A contact portion 164 connected to the coil; And a connecting portion 166 for connecting the stand 162 and the contact portion 164 with the elastic action of a spring.

At this time, the alarm sound hunting instrument 100 according to the present invention can be represented by an equivalent circuit as shown in Fig. 3 is a diagram illustrating an equivalent circuit of an alarm sound output device according to an embodiment of the present invention. 3, the horn 100 is connected to the horn output unit 150 through a coil through a horn switch 120 and an alarm switch 130, respectively, as shown in FIG. That is, the horn switch 120 is connected to a first portion of the iron core 110 where the coil is wound a few times less frequently, and the alarm switch 130 is connected to the first portion where the number of times the coil is wound on the iron core 110, 2 < / RTI >

Therefore, when the horn switch 120 is turned ON by the driver or the like, the power is supplied from the power supply section 140 to the first section to magnetize the iron core 110, and the oblique output section 150 The armature 156 is pulled toward the iron core by the magnetic force generated in the iron core 110 to move the armature 156 away from the stand 162 in the switching unit 158 and to release the contact unit 164 from the power unit 140 The power source is not supplied to the first part and the iron core 110 loses the electromagnetic force and the diaphragm 152 coupled with the armature 156 returns to its original position by its own elastic force, And the diaphragm 152 is connected to the stand 162. This operation is repeated so that the diaphragm 152 vibrates and outputs a sound through the resonance plate 154. [ In this case, when power is applied to the first portion of the coil, the magnetic force generated by the first portion is small in the number of turns of the coil, so that the inductance (resistance) value becomes small, The vibration of the diaphragm 156 is greatly increased and the vibration of the diaphragm 152 is further increased so that the sound output from the resonance plate 154 is output through the resonance plate 154. Therefore, .

On the other hand, when the alarm signal is received from the theft alarm device and the alarm switch 130 is turned on, power is supplied from the power source 140 to the first and second portions of the coil, The armature 156 is pulled toward the iron core by the magnetic force generated in the iron core 110 and the hammer 156 is moved from the stand 162 in the switching part 158 The contact portion 164 is detached from the power supply portion 140 so that the power is not supplied to the first portion and the second portion and the vibration plate 152 to which the armature 110 is coupled and the armature 156 is coupled The contact portion 164 is again connected to the stand 162 by the elastic force of the spring and this operation is repeated so that the vibration plate 152 vibrates and the alarm sound is output through the resonance plate 154 . That is, when power is supplied to the first and second portions of the coil from the power supply unit 140, the inductance (resistance) value becomes larger as the number of times the coil is wound on the iron core 110 is larger than the first portion The magnetic force generated by the iron core 110 is weakened. Accordingly, the moving operation of the armature 156 is not so large, and the vibrating operation of the diaphragm 152 is not so large, so that the resonance plate 154 A small sound is outputted through the alarm sound.

4 is a flowchart illustrating an alarm sound output method of a horn according to an exemplary embodiment of the present invention.

Referring to FIG. 4, the alarm sound / output device 100 receives a burglar alarm signal from the burglar alarm device or turns on a horn switch (S410).

That is, when the horn sounder 100 receives the burglar alarm signal from the theft alarm device, the alarm switch 130 is turned on. When the driver operates the horn switch 120, the horn switch 120 (ON). Here, the operation of the anti-theft alarm device corresponds to a technique common to the technical field of the present invention, and thus a detailed description thereof will be omitted.

Next, the alarm sound hunting machine 100 is supplied with power from the power supply unit 140 to the first portion or the first portion and the second portion of the coil wound around the iron core 110 (S420).

That is, when the horn switch 120 is turned ON, power is supplied from the power supply unit 140 to the first portion of the coil wound around the iron core 110, and when the alarm switch 130 is turned ON Power is supplied from the power supply unit 140 to the first and second portions of the coil.

The horn sound output unit 150 outputs a horn sound when power is supplied to the first portion and outputs an alarm sound when power is supplied to the first and second portions S430.

That is, when the power is supplied from the power supply unit to the first portion or the first portion and the second portion, the tilted output unit 150 generates a beep sound or an alarm sound according to the magnitude of the magnetic force generated by the electromagnet action of the iron core 110 And outputs it.

For example, when the horn switch 120 is turned on by the driver, power is supplied from the power supply unit 110 to the first portion of the coil to magnetize the iron core 110, The armature 156 is pulled toward the iron core by the magnetic force generated in the iron core so that the armature 156 is moved away from the stand 162 and the power source 140 is powered So that the iron core 110 loses its electromagnetic force and the diaphragm 152 coupled with the armature 156 returns to its original position by its own elastic force so that the abutting portion 164 is also pressed against the stand 162, and this operation is repeated to output a voiced sound through the resonance plate 154 as the diaphragm 152 vibrates.

That is, when power is supplied to the first portion of the coil from the power supply portion 140, the inductance (resistance) value becomes smaller as the number of times the coil is wound on the iron core 110 is smaller than that of the first portion and the second portion, The magnetic force generated in the iron core 110 becomes more severe and the moving operation of the armature 156 is increased due to the sensed magnetic force and the vibrating operation of the diaphragm 152 is greatly performed And outputs a loud sound through the resonance plate 154. At this time, the sound produced by the sound output unit 150 can be output to be 90 dB or more when measured at a distance of 2 m ahead of the vehicle.

On the other hand, when the burglar alarm device mounted on the vehicle is operated by a stranger or an intruder to generate a burglar alarm signal, when the horn interrupter 100 according to the present invention receives a burglar alarm signal from the burglar alarm device The alarm switch 130 is turned on and the power is supplied from the power supply unit 140 to the first and second portions so that the iron core 110 is magnetized.

Since the inductance (resistance) value of the first and second portions of the coil is larger than the inductance (resistance) value of the first portion, the currents due to the first portion and the second portion The value I2 is smaller than the current value I1 by the first part.

In Equation (1), V represents a voltage value, L represents an inductance value (H), and I represents a current value.

Therefore, since the current value I2 flowing through the first and second portions is smaller than the current value I1 of the first portion, the intensity of the magnetic force corresponding to the current value I1 becomes smaller, and the armature 110 The oscillation intensity of the diaphragm 152 becomes weak and the output of the resonance sound through the resonance plate 154 becomes small.

That is, the armature output unit 150 is configured such that the armature 156 is pulled toward the iron core by the magnetic force generated in the iron core 110 so that the armature 156 moves away from the stand 162, Is not supplied to the first portion and the second portion and the iron core 110 loses electromagnetic force and the diaphragm 152 coupled with the armature 156 returns to its original position by its own elastic force, The vibration plate 164 is also connected to the stand 162 by the elastic force of the spring. As the vibration plate 152 is oscillated by repeating this operation, the alarm plate 154 outputs a small audible alarm sound.

In other words, when power is supplied from the power supply unit 140 to the first portion and the second portion of the coil, the inductance (resistance) value increases as the number of times the coil is wound on the iron core 110 is larger than the first portion, The magnetic force generated in the iron core 110 is weaker than the magnetic force of the first portion so that the moving operation of the armature 156 is reduced and the vibration operation of the diaphragm 152 is also reduced. The resonance sound is output as an alarm sound.

As described above, according to the present invention, when a vehicle is parked, it can be used for a burglar alarm that outputs an alarm sound in a stolen state. It is possible to realize a sound horn sound output method combined with a sound horn and its alarm sound.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims and their equivalents. Only. It is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents. .
