The present invention relates to a sensory signal output device using an electromagnetic field for outputting vibration or sound or vibration and sound by vibration of a magnetic circuit in response to an alternating electric field.

In general, the sensory signal output device is a collective name for a speaker, a receiver, a buzzer, and a vibrator (including a vibrator) that converts an electrical signal input from a signal source into a mechanical signal to output sound or generate vibration force. can do.

Conventionally, such a sensory signal output device is exemplarily illustrated in the accompanying drawings, FIGS. 1A and 1B, while the magnetic circuit M reacts to a change in the electric field of the coil C to the vibration, that is, the carbon support S. FIG. The magnetic circuit M supported by the vibration vibrates up and down, and outputs a vibration force or sound (in the drawing, the symbol 'H' is a case).

The magnetic circuit (M) is, for example, alternately applied to the coil, the coil fixed to one side of the diaphragm is located in the gap between the magnet and the top plate which is laminated and fixed to the yoke and the upper surface of the yoke by sequentially bonding or welding It includes a yoke, a magnet, and a top plate in response to a magnetic flux formed in the air gap according to a change in direction of the signal (change in electric field).

In this way, the preset resonance point generates an overall error according to its own characteristic error of each component, even if the circuit is designed according to the correlation of the components.

That is, as shown in FIG. 2, assuming that the resonance point originally set to be obtained is 175 [Hz]. You will not get close output.

As such, even if an error occurs that is not included within a desired resonance point or an error tolerance, there is no device or method for correcting the error.

Since the occurrence of the error of the resonance point is treated as a characteristic defect according to the degree of the error, if the error occurs in the finished product, it is inevitably treated as a defect. In addition, even in the case of a good product, a difference in vibration force may occur at a single frequency due to a difference of 1-2 Hz, so that the tolerance of the good standard of the product specification may be largely set, and the use of the product may be in consideration of the large deviation.

Conventionally, as described above, if a defect occurs in a finished product state, since the characteristic correction is impossible and the finished product is discarded, there is a problem in that the productivity is reduced and the unit cost of the product is increased. In addition, even a good product has a problem that the deviation of the product is large.

According to the present invention, in the sensor signal output device 10 using an electromagnetic field for outputting a sensor signal by vibration of the magnetic circuit 2 in response to an alternating electric field, the magnetic circuit 2 accommodated in the case 1 vibrates. Approaching in the process characterized in that it comprises a attraction force means 11 for mutually attracting the magnetic circuit 2 to change the resonant frequency, and to change the acceleration of gravity at a single frequency.

The present invention can adjust the resonance point artificially by changing the acceleration of gravity in the finished product or semi-finished state only by detaching (including replacement) of the attraction force means, through which the error of the output characteristics can be easily corrected.

In addition, the present invention, by correcting the error of the output characteristics in the finished product state, significantly lowered the defective occurrence rate can not only improve the productivity, but also the product cost can be reduced and the quality of the good.

When the resonance point characteristic of the sensor signal output device 10 using the electromagnetic field for outputting the sensor signal by vibration of the magnetic circuit 2 responding to the alternating electric field is out of the error range, the magnetic circuit ( When 2) approaches in the vibration process, the attraction force means 11 for changing the gravity acceleration of the vibration by mutual attraction with the magnetic circuit 2 is attached to the case 1 accommodating the magnetic circuit 2, The error of the resonance point can be corrected.

This will be described in detail with reference to the accompanying drawings.

First, the present invention, as shown in Figure 15a of the accompanying drawings, the magnetic field of the magnetic circuit (2) reacts with the electromagnetic field of the coil (3) is supported by the elastic support (4), the alternating of the coil (3) Vibration force is generated in the process of linear reciprocating motion according to the direction of the signal. When the attraction force means 11 is provided in the case 1, the magnetic circuit 2 moves in the direction of the attraction force means 11. In the direction, the attraction force acts between the magnetic circuit 2 and the attraction force means 11, that is, the attraction force means 11, which is a magnetic body, is attracted to each other by the magnetic force of the magnetic circuit 2.

In this case, since the state vibrating naturally in accordance with the signal of the coil 3 is forcibly attracted by the magnetic force, the gravity acceleration is increased than the normal vibration state. Then, the resonance point is formed at the point where the gravity acceleration is maximum (the principle that the resonance point is formed near the maximum time point).

At this time, when vibrating in the opposite direction by the mutual attraction of the attraction force means 11 and the magnet (2b), it can be expected that the vibration force is reduced by the attraction force, but the support body 4 by the principle of pulling and releasing the bow In case of overcoming force and shooting, gravity acceleration is also increased to improve vibration force.

The resonance point due to the gravity acceleration and the gravity acceleration can be adjusted according to the diameter or thickness of the attraction force means (11). As a result, it is possible to correct the resonance point by artificially adjusting the diameter or thickness of the attraction force means (11).

This can be seen through the experimental result table (diameter change) shown in FIG. 16, which will be described below on the assumption that the reference value of the desired resonance point (resonant frequency) is 1.3 [g] or more at 175 [Hz]. do.

For example, looking at the first experimental value, the result of the initial characteristic test of the sensory signal output device 10 showed that the resonance point (resonance frequency) was 180.5 [Hz] and the gravitational acceleration at 175 Hz was 0.74 [g]. This is because the resonance point is higher than the standard, it shows a remarkably low gravity acceleration at 175Hz that the product requires. As a result, it falls short of 1.3 [g] which is the minimum required at 175Hz.

However, the attraction force means 11 of the present invention is attached to one side of the case 1 of the sensory signal output device 10, for example, A type, the attraction force means 11 having a diameter of 3θ and a thickness of 0.025t. The resonance point (resonance frequency) was 178 [Hz] and the gravitational acceleration was 1.14 [g]. It can be seen that the gravity acceleration was increased by 0.4 [g] at 175 Hz by reducing the resonance point by 2.5 [Hz] and correcting it within the error range of the reference resonance point.

Also, like the B TYPE, when the attraction force means 11 having a diameter of 4.7θ and a thickness of 0.025t was attached, the resonance point (resonance frequency) was 175.5 [Hz], and the gravitational acceleration was 1.37 [g]. It can be seen that the resonance point was lowered by 5 [Hz] to compensate for almost satisfying the reference resonance point (as well as within the error range of the reference resonance point) and the gravity acceleration was improved by 0.63 [g].

On the other hand, the experimental result table according to the thickness change of the present invention is shown in Figure 17, the following description, as in the case of the diameter change, the reference value of the desired resonance point (resonant frequency) is 1.3g or more at 175 [Hz] It will be explained under the assumption.

For example, looking at the first experimental value, the initial characteristic test results of any sensory signal output device 10 showed that the resonance point (resonance frequency) was 178.5 [Hz] and the gravitational acceleration at 175 Hz was 0.97 [g]. It has a resonant point higher than that of the standard, which shows a significantly low gravity acceleration at 175Hz, which is required by the product, and as a result, it falls short of 1.3 [g], which is the minimum required at 175Hz.

However, the attraction force means 11 of the present invention is attached to one side of the case 1 of the sensory signal output device 10, for example, A type, the attraction force means 11 having a diameter of 3θ and a thickness of 0.025t. The resonance point (resonance frequency) was 176.9 [Hz] and the gravitational acceleration was 1.46 [g]. It can be seen that the gravity acceleration is increased by 0.49 [g] at 175 Hz by lowering the resonance point by 1.6 [Hz] and correcting it within the error range of the reference resonance point.

Also, like the B TYPE, when the attraction force means 11 having a diameter of 3θ and a thickness of 0.04t was attached, the resonance point (resonance frequency) was 174.4 [Hz], and the gravity acceleration was 1.47 [g]. It can be seen that the gravity acceleration was improved by 0.5 [g] at 175 Hz by down-resonating the resonance point by 4.1 [Hz] and correcting it within the error range of the reference resonance point.

The resonance point correction state by the attraction force means 11 can be clearly compared through the graph shown in FIG. As shown in the graph, the characteristics of an early sensory signal output device showed a resonance point of 178.5 [Hz] and a gravitational acceleration of 0.92 at 175 [Hz], but a gravitational force of 3θ in diameter and 0.02t in thickness ( 11), the resonance point is lowered to 177 [Hz], the gravitational acceleration at 175Hz is corrected to 1.38 [g], and the attraction point 11 with a diameter of 4.2θ and a thickness of 0.02t is attached. This is also down to 175 [Hz], and the gravitational acceleration is corrected to 1.68 [g]. (Note that the graph is expressed as m / s ^ 2 instead of g (9.8m / s ^ 2), so dividing by 9.8 gives the g value described above.)

As described above, the present invention can adjust the resonance point by artificially changing the gravity acceleration only by detachment (including replacement) of the attraction force means 11 in the finished or semi-finished state of the sensory signal output device 10, thereby output characteristics The error can be easily corrected. In addition, the present invention can significantly reduce the failure rate by correcting the error of the output characteristics in the finished product state.
