METHOD AND DEVICE FOR DIMENSIONAL SOUND GENERATION

Technical area

The present invention relates to a sound generation system, that in particular for generating a dimensionally correct impression of the sound and for generating it a record is formed, which is in the It is able to generate or reproduce the dimensional impression of the sound.

State of the art

In a typical stereophonic sound reproduction system in which 2 loudspeakers are provided, a "dimensionally appropriate" Effect obtained by transmitting different sound or tone signals to the two speakers will. Therefore, if the speakers are positioned at 2 laterally spaced locations and the The listener is positioned behind the speakers and is looking towards a point between the speakers is, a certain sound that is only transmitted from the left speaker is considered by the listener coming from this source, since the left and right ears of the listener have an intensity difference capture and also capture a phase shift in order to

130616/0043

so to get the impression of the direction of the tone or sound. If another particular tone or sound of is transmitted to the right loudspeaker, the direction of this sound source can also be detected by the listener will. Therefore, the sound can be extended to the area encompassed by the two speakers will.

In the prior art, attempts have been made to to achieve an even larger dimension for the sound reproduction system, so that the impression is that the Sound comes from areas that are completely outside the more restricted area at and between comes in both speaker positions. Even if the applicant is not completely familiar with the operation of this Systems are familiar / fairly require such systems as Applicants' current understanding restricted operating conditions. For example, it is known that the conventional systems available to applicant are known, must be operated in an environment in which there is very little reflected sound, for example in an open room or within a room in which the walls are made of highly sound-absorbing Material. Furthermore, the systems known to the applicant are quite sensitive to this Location of the listener's head. Hence, if the person goes moves her head from a precise listening position, or turning their head moderately to one speaker or the other, a large part of the dimensional effect lost. Therefore, according to the existing understanding of the applicant, such systems are more laboratory-related in the stage Oddities have remained rather than become a system that is usable for general use.

130816/0043

It is believed that the conventional systems explained immediately above are based on the Knowledge operated from different places both in front of and behind the head of a person outgoing sound creates different sound patterns with respect to the person's ears. Hence a sound creates starting from a position in front of the person and offset by 30 ° to the left, clearly different relative sound patterns to the person's ears, opposite a sound coming directly from a point to the left of the person goes out. There is an intensity difference for the different frequencies and also a different one Phase shift detected by both ears of the person. It is believed that this phenomenon Used to cut through or control the sound coming from the speakers to make delicate adjustments the phase shift and the sound intensity at different frequencies to achieve for generating the effect of a better dimensional sound. However, as stated above, it is assumed that the sensitivity of such systems with regard to reflected sound and also the position of the head they do not apply to the general Let consumption become practicable.

There is also the recognition of the prior art labeled "crosstalk". Appearance, which under certain circumstances has the effect of the quality of the 2 speakers spaced apart to degrade the sound transmitted. To briefly explain this phenomenon, the sound from a right loudspeaker reaches both the right as well as the left ear of the person, with the left ear depending on at a slightly later point in time the distance between the loudspeakers, the listening angle and the distance from the listener is achieved (i.e. with one

130616/0043

304 U29

Time between 0 and 9ΟΟμ3) as well as with a slightly lower one Intensity than the sound reaching the right ear. The sound from the left speaker is roughly the same Wise regarding the left and right ear. If similar sounds or similar tones are emitted from both Loudspeakers lose some of the stereophonic effect, or at least reduce it as a result of this phenomenon of crosstalk. To the best of Applicant's knowledge, conventional systems have attempted the disadvantageous To reduce the effect of crosstalk by providing compensation signals that interact with the Combine crosstalk signals to create the correct phase shift.

It is a purpose of the present invention, a method and an apparatus for producing a more dimensionally accurate To achieve the sound effect, the method and the device for general use practicable are, in that they are less sensitive to reflected Sound and the position of the head are.

Disclosure of the invention

The apparatus of the present invention is provided to generate a dimensionally appropriate sound or audio signal, to be used with a pair of speakers where there is a play area, one on the right and one on the left Loudspeakers are positioned in a right or left loudspeaker position and wherein a listening area is present with a Listening position. There is one right and one in the listening area left ear position corresponding to the right and left ear position of the head of a person who is at the listening position can be provided and looks to the play area.

130616/0043

The device has a left input device for Receiving a left stereo signal and a right input device for receiving a right stereo signal. There are also left and right output devices intended for generating audio signals for the left or right loudspeaker.

There is a left main transmission facility for broadcasting a left main signal component corresponding to and similar to the left stereo signal to the left Signalau sgahg facility. Similarly, there is a right one Main transmission device for transmitting a right main signal component corresponding to and similar to the right one Stereo signal to the right signal output device.

There is a left-right compensation device that is used to Receiving the left stereo signal is designed to generate an inverted and delayed left-right compensation signal corresponding to the left stereo signal and to the transmit the left-right compensation signal to the right signal output device. Similarly there it is a right-left compensation device which is designed to receive the right stereo signal to generate an inverted and delayed right-left compensation signal corresponding to the right stereo signal and to the Transmitting the right-left compensation signal to the right signal output device. The two compensation signals are related to the corresponding main signal component by " a time delay period delayed within a predetermined time delay range.

Therefore, the left signal output device generates a left one Audio signal that is the main left signal component and the Having right-left compensation signal. The right signal output device produces a right audio signal that the

130616/6043

304U29

right main signal component and the left-right compensation signal having. The result is that when the left audio signal drives the left speaker and the right audio signal controls the right loudspeaker, the following occurs:

a. There is a left audio output with a left Main sound component and a right-left compensation sound component, where the left audio output is a primary path component of the left Loudspeaker to the left ear position and a secondary path component from the left loudspeaker to the: has right ear position,

b. there is a right audio output signal with a right one Main sound component and a left-right compensation component, where the right audio output signal is a primary path component from the right Loudspeaker to the right ear position and a secondary path component from the right loudspeaker position to the left ear position,

c. the left main sound component reaches the left Ear without extinction to a significant extent,

d. the right main sound component reaches the right ear position without extinction to a significant extent,

e. the left Hauf> t-sound component, which is based on its secondary Ways to · the right ear position is running in to a considerable extent due to the left-right compensation scarf component deleted or suppressed those on the primary path from the right speaker to the right Ear position is running,

f. the right main sound component, which is on the secondary path from the right loudspeaker to the left ear position running is to a significant extent due to the right-left compensation sound component deleted or

130616/00 43

304 H29

that travels from the left speaker along the left primary path to the left ear position.

The result is that a person is positioned so that the person's head is in the listening position / facing is directed to the transmission range, hears a dimensionally appropriate tone or sound with apparent Sound sources that are outside the transmission range of the two loudspeakers.

There is a time delay interval for each time delay period, which is the distance the sound will travel during the corresponding time delay period passes through. The device is further characterized in that the time delay range for the compensation signals a smaller time delay limit with a correspondingly smaller time delay limit distance and has a larger time lag limit with a corresponding larger time lag gap limit. The smaller and larger time delay distances include a range that is an optimal time delay distance which is equal to a value obtained by multiplying the sine of any of the Hearing angle is obtained with the stretch of the ear stand.

Each of the compensation signals expediently has a plurality of compensation signal components, each of which has one has different corresponding time delay distance components. At least one of these is useful Time delay distance components smaller than the optimal time delay distance. Also is expedient at least one more of the time delay distance components greater than the optimal time delay distance.

130616/0043

In the preferred form, at least some of the compensation signal components have decibel values that are lower as a decibel value of the corresponding main sound component are. At least one of the compensation signal components also has a decibel value that is consistent with the Frequency changes, with lower frequencies of this compensation signal component have a higher decibel value than higher frequencies of this compensation signal component.

In the preferred embodiment, the right and left main transmission devices have a frequency equalization device on. Each of these frequency equalizers generates its main signal component at a higher decibel level for lower frequencies and a lower decibel level for higher frequencies.

This device can also be used to generate records can be used, which in turn can generate dimensionally correct sound. In this embodiment is a stereo recording device in operative connection with the left and the right signal output device for receiving the left and right audio signal. The stereo recording device generates a stereophonic sound recording with right and left information channels corresponding to the left and right audio signals.

In this way, the left signal output device generates the left information channel, which is the left main signal component and contains the right-left compensation signal. The right signal output device generates the right information channel, which contains the right main signal component and the left-right compensation signal. Therefore controls if the sound reproduction is played using a stereo player with the right and left speakers is connected, the left information channel denotes

130616/0043

left speaker and the right information channel the right speaker.

In the method according to the invention, left and right stereo signals become left and right, respectively Entrance facility directed. A left main signal component corresponding to and similar to the left stereo signal is transmitted to a left signal output device. A right main signal component corresponding to and similar to the right stereo signal becomes a right signal output device transfer.

The left stereo signal becomes an inverted and delayed left-right compensation signal accordingly the left stereo signal. This is transmitted to the right signal output device. It is also from the right stereo signal an inverted and delayed right-left compensation signal corresponding to the right Stereo signal generated. This is transmitted to the left signal output device.

In one embodiment, the signal output device is used to generate sound via loudspeaker devices det. In another embodiment, the signal output device used to generate a sound recording, which in turn produces the desired sound components Can generate playback using a conventional stereo system.

The effect of the present invention is to produce a highly dimensionally accurate sound with relative high tolerance with regard to the position of the head and the angle of the listener. Further characteristics result from the following detailed description.

Best way to carry out the invention

In order to appreciate the novel features of the present invention, it is assumed that the detailed explanation of the

130-616 / 00 4 3

present invention a general analysis of the sound pattern or courses used in stereophonic recording. this will by first analyzing how stereophonic recordings higher quality are discussed, reference being made to Figure 1 for this part of the explanation is taken.

(a) Analysis of stereophonic recordings

In Fig. 1, 2 microphones M1 and M2 are shown, each other and which are positioned in front of an orchestra, indicated generally at 10 . and which includes a plurality of orchestral components (i.e. musical instruments 12a to 12g). Let it be assumed that the both mics M1 and M2 are positioned fairly close to the orchestra and a little more than 10 feet apart (approx. 3m) apart.

The sound from the instrument 12f travels on a 1st shorter Path 14 to microphone M2 and on a second longer path 16 to microphone M1. Obviously the microphone is drawing. M2 picks up the sound from the instrument 12f with a higher intensity than the microphone M1. There is also a phase shift, because the microphone M1 picks up the sound in an order of magnitude of about 1/100 of a second later can be used as the microphone M2, since the sound must continue to run to the microphone M1.

Similarly, sound reaches, ^e £ on the instrument 12b emanating / microphone M1 earlier and with higher intensity than the sound of the instrument 12b, which reaches the microphone M2. At some intermediate point, ie at the point of the instrument 12d, the sound reaches the two

13.0616 / 00

304U29

-η-

Microphones Μ1 and M2 at approximately the same time and with the same intensity. The sound transmitted to the microphone M1 is used to generate a 1st signal that in turn transferred to the stereo recorder and in of the recording is reproduced in such a way that when the recording is played back this signal, the corresponds to the sound at the microphone M1, reproduces a sound in one of the loudspeakers that is an essential Is reproduction of the sound reaching the microphone M1. Similarly, the one reaching the microphone will be M2 Sound recorded in such a way that when the record is played, the signal that the other Controls loudspeakers that respond to the sound that goes to the Microphone M2 is transmitted.

Let us now discuss the situation in which these two specific sound signals are played on a recording and reproduced in a stereophonic system, referring to Fig. 2. It is assumed that the the signal generated at the microphone M2 is used in a way to generate sound in the left loudspeaker LS, while the signal generated at the microphone M1 is in the recording for reproducing a sound in the right one Speaker RS is used.

With regard to the sound generated by the instrument 12f shown in FIG. 1, the loudspeaker LS generates the same First sound with a higher intensity level. As already stated, this sound has a 1st and a 2nd component Ll and Lr reaching the left and right ears Le and Re, respectively. At this moment the two grasp Ears Le and Re a difference in the intensity of the two sound components Ll and Lr and also a phase shift from possibly 100 to 300μ3, so that a very definite one There is sense of direction from the left speaker Ls. However, about 1/100 of a second later - essentially

13061 6/00 A3

30-129

the same sound originally generated by the instrument 12f from the right speaker RS reproduced at a lower intensity level according to the two components Rl and Rr. If the sound of the two loudspeakers LS and Rs (correct: RS) had the same intensity and phase, none would Stereophonic effect exist. However, since the sound from the left speaker LS has greater intensity and has different phase, there is some of the stereophonic effect, although this to a certain extent is hidden or suppressed by a very similar sound, that of the right loudspeaker RS goes out.

Now consider the sound coming from the center arranged instrument 12d go out. As already stated, since the distances from the instrument 1 2d to the two microphones M1 and M2 are essentially the same, the times and the intensity of the sound M1 and M2 are essentially the same. '

Therefore, when the sound from the instrument 12d is reproduced in the two loudspeakers LS and RS, the sound from the two loudspeakers LS and RS, the go through the main path components Ll and Rr, the left one and the right ear Le and Re simultaneously. The two secondary sound components Lr and Rl reach the two ears Le and Re simultaneously, but possibly around 100 to 300με later than the Kiupt-Scha 1! components Ll and Rr.

It is now assumed that, with regard to the reproduced sound, the corresponds to that produced by the instrument 12d is generated, the two secondary sound components Lr and Rl are both canceled or suppressed, so that Le only has a left I & upt switch component Ll and that

130616/00 43

304U29

(correct: Pe)
right ear Rr only hear the main right component Rr. If the two ears hear essentially the same sound with the same intensity, the impression is given that the sound is coming from a central point immediately in front of person P.

(b) Theory of the present invention

To proceed now with a discussion of the present invention continue: the present invention is based on the theory that 2 corresponding sounds (i.e. sounds that originating from the same issuing or originating instrument when the original recording was made), their corresponding sounds can be recorded sequentially (i.e., this occurs when the instrument is closer to one recording microphone than to the other) to produce a much wider dimensional effects can be used than the area occupied by the loudspeakers. These sounds can be used to generate a almost perfect dimensional effect can be used, in which the music seems to affect the listener emotionally "surrounds".

Even if the theory suggested below, is believed to be applicable to the appearance of the present invention, it should be emphasized that regardless of determined the accuracy or validity of the following theory it has been found that the present invention is capable of this almost perfect dimensional effect of the sound.

Proceeding further with the presentation of the theory of the present invention and with further reference to FIG. 2, it is assumed that two sounds corresponding to those originating from the instr: .r ^c r; t 12f are now in the

13 061 δ / 0043

both speakers LS and RS are reproduced. When the sound picked up by the microphone M2 through the loudspeaker LS is reproduced, the sound of the instrument 12f at an earlier point in time becomes along the two Transfer path components Ll and Lr. As already explained, in the first moment,, lies in the, the two sound components Ll and Lr reach the ears Le and Re, something of the dimensional effect before, by ^ that the listener clearly has the impression that the sound originates from the loudspeaker LS.

It is assumed, however, that the secondary noise component Lr something is eliminated in such a way that at the first moment only the left ear Le hears the sound that runs along the Main sound component path Ll runs. Because the right ear Re does not hear anything from this sound, the momentary impression is that is generated for the person P, that the sound of comes from a position immediately closer to person P's left side.

Hence the immediate impression is that the sound completely outside the speaker area and somewhere near the left side of the person.

About a 100th of a second later it is now assumed that the reproduced sound _; which corresponds to that of the instrument 12f is now output from the right loudspeaker RS. It is further assumed that the secondary sound component Rl has been eliminated, so that only the right ear Re hears the sound coming from the loudspeaker Rs (correct: RS). The impression is that there is a second instrument 12f, which in some area immediately on the right. Side of the person who is also outside the speaker area.

130616/0043

Let us now consider the reproduced sound, which the Corresponds to sound originating from the instrument 12d. When the two secondary path components Lr and Rl are completely eliminated and when that of the loudspeakers LS and RS emitted sounds at substantially the same time and with substantially the same intensity occurs, there is a very clear impression that the sound corresponding to that from the instrument 12d comes from a source immediately in front of the person. With regard to the sound emitted by the instruments 12c and 12e, since the distance difference between these instruments and the microphones M1 and M2 is somewhat smaller is the time delay and the difference in intensity, with which these sounds are recorded, somewhat less than in the case of instruments 12b and 12f. Consequently if the reproduction of this sound in the two loudspeakers LS and RS is timed a little closer to one another, see above that the left ear and the right ear Le and Re these two closer to the same intensity and slightly closer to each other listen in a timeframe. Therefore, the dimensional effect in terms of the sound can affect those correspond to those of the instruments 12e and 12c . are predicted to be somewhat less than in the case of the sounds emitted by instruments 12b and 12f come. ■ '.

The overall effect of this is the rather surprising creation of the impression that the sound is "perfectly dimensional" is in that the listener seems to be somehow within the sound or in some way surrounded by the various sound sources seems to be. It has also been found that in the present invention the apparatus can be so arranged may that they are not overly sensitive about that

Location or angle of the listener's head

is. For example, assume that the listener is more
is attracted to a sound that appears to be coming from the direction on the left and the listener turns his head towards that speaker. The dimensional effect produced by the present invention is not significantly reduced. Further, the listener is able to keep his head moderate

(c) Device according to a 1st embodiment of the
present invention

The apparatus of the present invention is shown in FIG. There are left and right stereo signals that at connections L (IN) or R (IN), which in turn lead directly to a left or right frequency equalizer A (L) or. A (R) are transmitted. Each of these frequency equalizers A (L) or A (R) is or can be one of those known in the art, each for controlling the power of the output signal works as a function of frequency. The output signal from the frequency equalizer A (L) is fed to a summing point C (L) and then via an amplifier (L) to the left loudspeaker S (L).

130 616/0043

304U29

In the same way, the output signal of the right frequency equalizer A (R) is fed directly via a right summing point C (R) to a right amplifier (R) for control of a right speaker S (R).

In addition, the left stereo input signal from L (IN) is fed to an inverting device B (LR) which changes the phase of the signal at L (IN) inverted by 180 °. The output signal of the inverting device B (LR) is in turn over 4 channels transmitted to 4 time delay frequency equalizers, which are designated with b1 (LR), b2 (LR), b3 (LR) and b4 (LR), respectively. Each time delay frequency equalizer b1 (LR) up to b4 (LR) has 2 functions, firstly the size of the inverted signal depending on the frequency and secondly the signal by a predetermined amount of time to delay.

The collective or common output of the 4 time delay frequency equalizers b1 (LR) to b4 (LR) generate a compensation signal that goes to the right summing point C (R) is transmitted. This left-right compensation signal becomes the main right stereo signal from the right frequency equalizer A (R) is given / superimposed, this combined or sum signal in turn controls the right loudspeaker S (R). thats why the output from the speaker S (R) is a sound pattern or sound curve corresponding to the sum output signal from the summing point C (R).

In the same way, the right stereo input signal at R (IN) is transmitted via an inverting device B (.RL), which inverts the signal by 180 °. The output signal from the inverting device B (RL) becomes a 2nd set of 4 time delay equalizers via 4 channels transmitted, which are designated with b1 (RL), b2 (RL), b3 (RL) and b4 (RL). As with the other time

1306 1 6/00 A3

304H28

Delay frequency equalizers b1 (LR) to b4 (RL) (correct: b4 (LR)) it is the function of the 2nd sentence the time delay frequency equalizer b1 (RL) to b4 (RL) to generate a right-left compensation signal, which is transferred to the left summing point C (L). That to the right (correct: left) summing point C (L) transmitted compensation signal becomes the left I & upt stereo signal, which is from the frequency equalizer A (L) is output, superimposed to produce a combined or summed signal that the left speaker L (S) (correct: S (L)) controls.

The intensity of each compensation signal is set by an associated switch Sw (L) or

Sw (R), which is between the input L (IN) or R (IN) and the associated .Inverter B (RL) or B (LR) is arranged, controlled. This switch Sw (L) or Sw (R) is shown somewhat schematically in Fig. 4, in which 3 voltage divider resistors R1, R2 and R3 are arranged in series. When the switching element E is open, the signal is sent to the associated inverter B (RL) or B (LR) with low intensity, i.e. about 6 decibels below the level of the signal at L (IN) or R (IN). When the switching element E is closed, the intensity of the compensation signal is about 3 decibels below the signal L (IN) or R (IN) raised. Hence the switches Sw (R) and Sw (L) act as "injection switches" to either Increase or decrease the intensity of the compensation signal to increase or decrease the dimensional - * - th effect of the generated sound.

In addition, the output signal is from the left summing point C (L) is fed back via a left time delay device D (L) back to the left input terminal L (IN)

130616/0043

30AU29 ■ -24-

In the same way, the output from the right Summing point C (R) fed back to the right input terminal R (IN) via a right time delay device D (R). Of course, each of the components mentioned is a conventional component used in the field known in electronics, each of which may take any of several conventional forms. For example are in a book entitled "Operational Amplifiers, Design and Applications", by Jerald G. Graeme, Gene E. Tobey and Lawrence P. Huelsman, published by McGraw-Hill Book Company, Copyright 1971, such frequency equalizers discussed in Chapter 5 entitled "Phase Compensation". Such facilities are also in and by a book entitled "Linear Applications Handbook" sold by Radio Shack the catalog number 62-1373, especially identified on page AN 64-9. Hence, it is a detailed explanation none of these components are included here.

As mentioned above, the 1st set is the time delay frequency equalizer b1 (LR) to b4 (LR) provided for generating a delayed output signal, the intensity of which is changed as a function of frequency. The way this is done is in the table of FIG. 5 explained. From Fig. 5 it can be seen that the output signal of b1 (LR) increases by one time increment ti or 11Ομε is delayed. Next is the size of the Output signal at ti equal to the input signal to the inverter B (LR) until a frequency of 8 kHz is reached, after which the output signal is at zero. Regarding that 2. Time delay frequency equalizer b2 (LR), the time delay t2 is ΙδΟμε. The size of the output signal is similar to that of unit b1 (LR).

1306 16/0043

-2X-

With regard to the 3rd time delay frequency equalizer b3 (LR), the delay period t3 is 370μ3. The time delay period t4 of the 4th time delay frequency equalizer b4 (LR) is 690μ3. With regard to the size of the output signal of these two components, component b3 (LR) has an output signal with 3.5 decibels above the input signal to inverter B (LR) for frequencies up to 200 Hz. For the 4th time delay frequency equalizer b4 (LR), the output signal for frequencies up to 400 Hz is 3.5 decibels above the level of the input signal ^to inverter B (RL). For each of the components b3 (LR) and b4 (LR), after the initial output signal, which is 3.5 decibels higher, the output signal returns to a level that is equal to the input signal to the inverter B (LR) until the frequency of 8 kHz is reached , after which the output signal drops to zero. The operation of the 2nd set of time delay frequency equalizers b1 (RL) to b4 (RL) is identical to the 1st set, so that the table according to FIG. 5 can be applied in the same way to the 2nd set.

It was found that the efficiency of the system of the present invention can be increased by controlling the intensity of the main left and right signals Main signal as a function of frequency. The way in which this is done is determined by the Representation according to Fig. 6 reproduced, in which the intensity of each frequency equalizer A (R) and A (L) emitted sound is plotted against the frequency. It can be seen that the intensity of the sound generated is maximum at 20 Hz, at which it is 6 decibels above the signal arriving at L (IN) or R (IN). Then falls they decrease with a substantially constant ratio to a level at 400 Hz at which there is no amplification of the signal takes place. This intensity remains constant until it approaches the 4 kHz range in which the intensity of the

1306 16 / 00A3

304U29

Sound drops to -8 decibels below the level of the incoming signal, after which the sound level falls back to the normal level rises back and remains at that level until it reaches the 20 kHz range.

(d) General Operation of the Present Invention

To explain how the present invention works, let a person P come to a place behind and with equal distance from the two speakers <? ' (L) and S (R) arranged. To achieve a suitable frame of reference it is assumed that the two loudspeakers S (R) and S (L) and the person P are arranged there, which can be referred to as "play area", where the speakers S (L) and S (R) in a front position and wherein the person P is in a rearward position. The two speakers S (R) and S (L) are arranged along a base axis 20 and spaced from one another by a predetermined distance. It gives a longitudinal axis 22 perpendicular to base axis 20 equidistant from the speaker positions S (R) and S (L). Person P is in a "listening area" 24 arranged, which is the area that surrounds the head of person P immediately. The head of the person P is arranged in a "listening position", the is a position on the longitudinal axis 22 in an ideal listening position for the device. The person P has a right ear Re and a left ear Le.

To explain the mode of operation of the present invention, let us first consider a very short time increment of an audio signal entering the left stereo input L (IN). This sound increment will directed directly to the left frequency equalizer A (L),

130616/0043

whose output signal is referred to as the "left main signal" which is led to summing point C (L). At the summing point C (L) there is also a sound increment that is from the right input R (IN) and delivered by the inverting device B (RL) and through 4 time delay frequency equalizers b1 (RL) to b4 (RL) to the summing point C (L) is performed. This additional sound increment can may be referred to as the "left-right compensation signal". Since the time delay for each of the 4th time delay frequency equalizers b1 (RL) to b4 (RL) is different from each other is the total sum of this left-right compensation signal formed from separate signal sections that are sequentially received at the input R (IN) are. The invention is designed so that the total or cumulative effect of the compensation signal that the The main signal from the frequency equalizer A (L) is superimposed, is not large enough to produce any noticeable To achieve degradation of the main signal from the frequency equalizer A (L).

When this combination signal increment (i.e. the left Main signal with the superimposed right-left compensation signal) from summing point C (L) to the left loudspeaker S (L) passes, for the purpose of analyzing the sound emitted by the loudspeaker as longitudinal two sound path components are viewed as running, a primary path component Ll leading to the left ear Le the person P is transferred, and a secondary T'Jeg component Lr, which is transmitted to the right ear Re. The left main sound is reached on the path component Ll the left ear Le with no substantial interference or perturbation so that the left ear Le hears a substantially unattenuated main left sound which itself results from the signal increment entering the left stereophonic input L (IN).

130616/0043

However, this is not the case with the main left sound on the secondary path component Lr. It turns out that the secondary path component Lr to the right ear Re something is longer than the primary path component Ll. The left one Main sound that traverses the secondary path Lr is partially canceled or suppressed by the sound, which comes from a left-right compensation signal, which comes from the left stereophonic input L (IN) that goes to the right summing point CR (correct: C (R)) crosses by first passing through the inverter B (RL) via b4 (LR) (correct: and via the time delay frequency equalizer b1 (LR) to b4 (LR)). The sound due to the left-right compensation signal generates a compensation sound on the right Loudspeaker S (R), which is superimposed on the sound generated by the right main signal, which is the right speaker S (R). The sound from the loudspeaker S (R) passes through a right primary Path component Rr and a secondary path component Rl. Because the path component Rr is shorter than the secondary way Lr, becomes the left

Right compensation sound delayed to the extent that that the left-right compensation sound reaches the right ear Re at approximately the same time as the corresponding left main sound increment, the longitudinal the secondary path component Lr is running. Because the compensation sound is phase shifted by 180 ° due to the inverter B (LR), the compensation sound cancels at least partially the left main sound increment, the traverses the secondary path Lr. The net effect is that the left ear Le is the main left sound increment in the essentially unattenuated, while the right ear Re hears the left main sound increment very little or with hears a significantly weakened level.

130616/0043

Regarding the right-left compensation signal, its Origin at the right input R (IN) and which is transmitted to the left loudspeaker S (L) has already been carried out that this signal is superimposed on the left main signal L (IN), which is from the frequency equalizer A (L) to the left Loudspeaker is transmitted. However, if the superimposed part of the canceling sound from the left speaker S (L) travels along the primary path L1 to the left ear just before a corresponding main right sound from the right loudspeaker S (R) is emitted and the secondary path Rl runs to the left ear Le, delete the compensation sound increment, that traverses the path of Ll and the right primary sound coming from the right loudspeaker Ls (correct: S (L)) and the component path Rl runs through each other essentially at the left ear Le from.

From the above description it is readily apparent that the output from the left loudspeaker S (L) Sound is heard essentially from the left ear Le alone, while that from the right speaker Rs (correct: S (R)) originating sound is essentially only heard through the right ear Re. Without the support of The analysis accompanying the invention is believed to be the initial reaction of a person to the mode of operation first Considering the present invention, it will conclude that the present invention has some of the stereophonic effect destroyed, which is obtained by the two speakers. That is, it can be discussed that, there a single sound coming from the left loudspeaker Ls (correct: S (L)), only the left ear Le and does not reach the right ear Re, the left and the right ear no differentiation in the intensity and the Be able to phase shift the same sound that travels different paths to the two ears,

130 616/00 43

whereby a valuable feeling of the direction of the source what is part of the stereophonic effect is lost. The first reaction contains some true elements because the present one Invention in a sense eliminated some of the traditional functional features of stereophonic sound or at least weakens. However, this analysis is incomplete as it does not take into account the type of sound which are reproduced in a stereophonic recording will.

The discussion will be briefly recalled under the heading "Theory of the Present Invention" with consideration of the effect of eliminating was given by sound traveling along the two secondary paths · Lr and Rl. This was made with regards to playing of the sound wave recorded in a stereophonic system such as that shown in FIG. A summary of this discussion shows that the sounds recorded with a substantial time delay are (such as those that come from the instrument 12f according to FIG. 3 (correct: FIG. 1)), one clear produce different impression for the listener if the sound along the paths Lr and Rl essentially are eliminated. Some of the sounds seem to move out of the transmission range of the two speakers, to "surround" the listener in a sense. Other sounds appear from the transmission range between to originate from the speakers. Still other sounds give an intermediate impression that they are "somewhere in between ". As this is under the previous section entitled" Theory of the present Invention "had been discussed, these comments will not be repeated.

130616/0043

Regarding the application of this theory to the actual Operation of the present invention is not a complete elimination of the present invention the sounds traveling along the secondary paths Rl and Lr. For example, let the signal increment again considered entering the left input port L (IN). This left signal increment has one earlier left main sound, which is emitted by the left loudspeaker S (L), with a delayed Compensation signal is emitted from the right speaker S (R). The compensation sound that traverses the path Rr has a delete function. However, the compensation sound becomes the secondary path Rl runs through to the left ear, not extinguished. However, since the compensation sound is achieved from the right one Loudspeaker S (R) not only opposite the corresponding main sound from the left loudspeaker S (L) is delayed, but also traverses a longer secondary path Rl, the corresponding compensation sound from the loudspeaker S (R) the left ear Le essentially later than the main sound that traverses the path Ll. It was found that this was not essential Deterioration of the main sound component

result! latte) operation of the invention with respect to the position the angle of the head

It has already been stated above that the vör-t invention can work effectively even in circumstances where the person turns their head in one direction or the other, or turns their head in sideways shifts to a moderate extent. To explain this particular side of the present invention, reference is made to FIG. Referenced. In Fig. 7, the right and left are

130616/0043

304.U29

Loudspeaker S (L) or S (R) and the listening position shown schematically. As already explained, there are Base axis on which the two loudspeakers S (L) and S (R) are arranged, and the longitudinal axis, which is perpendicular to the base axis and the base axis, bisected. Additionally There is a right and a left hearing axis, which extends from the horst to the right and left loudspeaker S (R) or S (L) extend. The right hearing axis forms a right hearing angle with the longitudinal axis, and in the same way the left hearing axis forms a left hearing angle with the longitudinal axis. The listener's left and right ears are denoted by Le or Re, the "ear distance" also being denoted. For the purpose of this analysis is the ear spacing Assumed to be 7 inches (17.8 cm).

Reference is now made to Fig. 8 which shows the listening position and shows the right and left ears Re and Le on an enlarged scale. In addition to showing the longitudinal axis, the right and left hearing axes and the right and left hearing angles are also the primary and secondary Sound path components Rr and Rl, Lr, Ll shown. Since the two loudspeakers in general from the listening area by one large distance with respect to the distance between the two ears Re and Le are spaced apart, the left. primary and secondary paths Ll and Lr can be assumed to be parallel to each other and the right primary and secondary paths Rr and Rl can also be viewed as parallel to each other.

In the following analysis, the term "time lag distance" is used used to denote an increment of distance over which the sound travels during a given delay period. Therefore, with a sound propagation of about 1080 feet per second (about 333 m / s) (depending on the ambient temperature) for a time delay of ΙΟΟμβ der Time lag distance about 1.3 inches (about 3.3 cm).

130616/004

If the head of a person is positioned exactly in the listening position and if the person is looking parallel to the longitudinal axis, an ideal signal cancellation should be achieved in the present invention, to have a time delay distance equal to a value obtained by multiplying the sine of the hearing angle by the ear distance. This ideal time lag distance is shown graphically at "x" in FIG. Assuming the two speakers are arranged so that the two hearing angles are between 30 ° and 45 °, the sine value is between 0.5 and 0.707. Assuming the ear distance is between 6 and 8 inches (about 15 to 21 cm), the range of the ideal time delay distance is in the range between 230μ & 460μ3.

Let us first consider the movement of the person's head forwards and backwards around the longitudinal axis. Since the loudspeakers S (L) and S (R) are generally arranged at a substantial distance from the listener in relation to each other on the distance between the ears, it is very easy to see that there is limited movement of the head forwards and backwards of the person (up to a few feet) results in a very small change in the corner of their ears. Consequently there is a very small change in the value of the ideal time delay distance. Therefore, the forward and substantially moving the person's head backward little influence in the present invention.

It is now assumed that the listener has his head in a The extent to which the listener is looking directly along the right listening axis to the right loudspeaker. The positions of the left and right ears in this position are with LeV and Re 'denotes. The exact point in relation to the person's ears about which the rotation is occurring varies slightly

130616/0043

person to person, however it is generally reasonable to assume that this pivot point occurs at a point directly between the ears Le and Re of the

himself
son lies. Thus, with continued reference to Figure 8, it can be seen that the left ear Le has been moved closer to the right speaker a distance "y" which is equal to half the ideal time delay distance "x". Furthermore, the left ear Le has also moved closer to the left loudspeaker S (L) by a distance "z" which is only slightly smaller than the distance "y". Further analysis shows that when the ear Le moves from its initial position to the rotated position Le ¹ , the left ear Le has in effect moved laterally by a distance increment denoted by "m" in FIG . With the ear in position Le ¹ , in order to achieve ideal cancellation, the change in the ideal time delay interval should be equal to twice the value 'Vn' multiplied by the sine of the hearing angle.

From the above analysis it can be seen why the angular movement of the person's head around the listening position is a ring has a debilitating effect on the operation of the present invention. One Angular movement of up to 30 °, for example, achieves a relatively greater forward movement and a relatively small sideways movement. As stated earlier, the system of the present invention is quite insensitive forward and backward movements of the person's head around the listening position. Therefore, the only one Effect that actually affects the angular movement of the The head of the person must be taken into account, the limited lateral movement to or away from the longitudinal axis, which actually changes the time delay distance.

130616/0043

The effect that the lateral movement (i.e. the movement perpendicular to the longitudinal axis) has on is now considered has the time delay distance. Reference is made to FIG. 9, which is a representation similar to that according to FIG Figure 8 shows the person's right and left ears Re and Le in the listening position. Be it assume that the person moves their head to the right without moving forward and without turning. Four positions are shown for each ear. The left ear is shown as in its ideal position and then becomes moved to the right by 3 increments, with each increment

is equal to a quarter of the ear distance. In the same The right ear is shown in its original position Re, as well as in 3 spaced positions right, where each distance is equal to a quarter of the ear distance.

When the left and right ears are in the ideal position in Le and Re, the ideal time lag distance remains based on the value of the ear distance multiplied by the sine of the hearing angle. When the left ear is to the right moved a distance equal to a quarter of the ear distance corresponds to (i.e. to the position Le (a)), the left ear moves simultaneously from the left speaker S (L) further away and closer to the right speaker S (R). Each increment of change is equal to the distance increment the lateral movement multiplied by the sine of the hearing angle. The effect of these two increments is cumulative such that the effective or net change in the ideal time lag distance with respect to the left Ear is equal to twice the lateral movement of the left ear multiplied by the sine of the corner of the ear. If the left ear reaches the position of the longitudinal axis (at Le (b)), the ear is equidistant from both loudspeakers. Therefore, the time delay distance is one

130616/0043

To achieve sound cancellation, reduced to zero. One further movement of the left ear to position Le (c) indicates that there is indeed a negative time lag distance to achieve extinction. That is, the canceling or suppressing sound from the right one Loudspeaker S (R) must be emitted before the left main signal, which comes from the left loudspeaker S (L).

With regard to the right ear Re, it follows that for each incremental movement to the right the ideal time delay distance increases at the same rate or speed as it decreases for the left ear. thats why at the positions Re (a), Re (b) and Re (c) the time delay distance 1 1/4 of the ideal time delay distance or 1 1/2 of the ideal time delay distance or 1 3/4 of the ideal time delay distance.

In the present invention, the compensation signal is provided over several spaced apart time delay increments transfer. The selection of these time delay increments was achieved partly analytically and partly empirically. The time delay spacing increments for the various time delay increments are as follows:

Time delay increments in inches or in cm

1.53 (4.04) 2.34 (6.18)

4.81 (12.2)

8.97 (22.8).

With continued reference to Fig. 8, assume that the ear spacing is 7 inches (about 17.8 cm) and that each the listening angle is 45 °. Hence the ideal time lag distance is approximately 5 inch ica. 12.7 cm). If the

130616/0043

Time delay increment in Microseconds ti 110 t2 180 t3 370 t4 690

Head of the person is arranged centrally on the longitudinal axis, it results that the compensation sound in the time delay increment t3 (which has a precise time delay distance of 4.81 inches (about 12.2 cm)) is the primary extinguishing sound is. When the person moves their head sideways to the right for the left ear that is closer moved to the longitudinal axis and therefore requires a shorter time delay increment, the canceling sound comes with time delay increments of first t2 and then ti into play. However, the effect is for the right ear of the canceling sound with a time delay increment of t3 continues to be effective because the right ear further away from the longitudinal axis, however, it is somewhat weakened. Hence it can be seen that, with further reference on Fig. 8 when the person attaining the posture labeled Le (a) and Re (a) continues to operate with the suppression or annihilation phenomenon.

Regarding the sensitivity of the compensation signal Lage is reminded that a sound with a fundamental frequency of "mean C" (i.e. 264 cycles per second) a fundamental wavelength of nearly 4 feet (approx.

has·

1.22 m) "Even for a 1000 cycle per second tone, the wavelength is about 1 foot. Hence Substantial sound cancellation can also occur even if the deviations from the ideal time delay abs tand is on the order of a few inches or more (a few centimeters).

Hence, even if the person reaches the position of the ears at Le (b) and Re (b), there is an essential one Annihilation effect as the annihilating sound waves are quite insensitive to moderate phase shifts. When the person's head continues is moved to the right, it results / that the extinction

130616/0043

304 U29

Appearance at the left ear Le is further weakened and there is still quite a degree of extinction appearance at the right ear due to the compensation sounds that have time delay increments of t3 and t4. For example, the cancellation sound is fully effective with the time increment t4 when the person their head nearly 5 1/2 inches (about 14 cm) from the long axis moved sideways to the right.

When the person has moved their head a substantial distance to one side or the other, receives the ear, which is further away from the longitudinal axis, further something of the dimensional effect (the dimensionalizing effect) but at a reduced level. However, it is believed / that the other ear, the has moved along the longitudinal axis, has lost a significantly greater degree of the dimensional effect. The psychological result of this is that the person tends to move their head back towards the ear, which has lost more of its dimensional effect. That said, the person tends to put their head back in Direction to move on the longitudinal axis, so that the the The ear closer to the longitudinal axis moves back over the longitudinal axis and more of the dimensional effect is obtained.

Regarding the various frequency equalizers that the Change the intensity of the sound as a function of the frequency (as shown in FIGS. 5 and 6) Values that were ultimately chosen from an empirical analysis trying out different combinations of sound intensities. The real effect on the listener through the frequency-intensity pattern is exercised, which is set out here is considered by the inventor to be perfectly sufficient. However,

130616/0043

Changes are made to change the effect in order to to satisfy the individual listener.

The approximate range for time delay increments can be changed and the amount of change depends to some extent on the relative intensity of the main signal component and the compensation signal components away. In general, it is assumed that the ranges are approximately as follows:

Time delay

Time delay distance range in increment inches (in cm)

ti 1-3 (2.5-7.6)

t2 2-4 (5.1-10.2)

t3 3-7 (7.6-17.8)

t4 6-12 (15.2-30.5).

(f) Reflected sound

It has already been pointed out that one of the problems with prior art systems presented to applicant are known, that is, that reflected sound a substantial deterioration of the> dimensional effect evokes. In the present invention, it should be noted that any combined signal received from the summing points C (L) and C (R) back to the input source L (IN) or R via a time delay device D (L) or D (R) (IN) is returned. The amount of time delay is δΟΟμβ, which is slightly longer than the longest time delay increment the time delay frequency equalizer b4 (RL) and b4 (LR). The effect of this is the overall signal (the main SLgnal plus the compensation signal) through the system. Additionally

130816/0043

the overall signal is not just through the same summing point but also directed to the opposite summing point through the crossover circuit.

One of the primary reasons for this is that the reflected Noise should also be compensated to a certain extent. In numerous circumstances the speakers are stereo placed on the floor, near the floor, or possibly in a corner. It is therefore to be expected that sound from reflecting off the floor and / or walls and to the listener with a time delay of the order of may be directed about 1 ms. It is assumed that this feedback mechanism D (L) and D (R), the is fed back and delayed by the system, at least partially compensated for this reflected sound.

It is recalled that, of course, the foregoing analysis is not to be considered entirely exhaustive. As already stated, was independent of the validity or accuracy of this analysis determined that the device produced this dimensional effect and a remarkable tolerance for angular and positional deviations the position of the person's head.

(g) Device according to the 2nd embodiment

The recording apparatus of the present invention is shown in FIG Fig. 10 reproduced. There are left and right input terminals L (IN) and R (IN). The signal inputs to these connections L (IN) and R (IN) should be stereo signals, as indicated by the microphones M1 and M2 Fig. 1 can be generated. There are at least 2 ways to achieve this, one of which is shown in solid lines in Fig. 10 and the other of which is shown in phantom in Fig. is shown.

130616/00 A3

One method is to make the recording facility like them is shown in Fig. 1, and to use the two spaced microphones M1 and M2 with the respective To connect input connections L (IN) or R (IN). Therefore the two connections L (IN) and R (IN) receive Stereo signals, with corresponding sound components being present in each signal with time delays and Changes in intensity between the corresponding components of the signal.

An alternative method of achieving the input signals to the terminals L (IN) and R (IN) is _y simply play with a stereo player, a stereo recording use which have been prepared in accordance with the system of FIG. 1, ₇ and this record. Then, instead of routing the signals generated by the playback device to the loudspeakers, these signals are routed to the input terminals L (IN) and R (IN). This method is shown in broken lines in FIG.

The left and right signals in turn become a left directly from the L (IN) and R (IN) terminals or a right frequency equalizer, which are designated with A (L) and A (R). Any of these frequency equalizers A (L) or A (R) is or may be any of those known in the art and each controls the output power as a function of frequency. The output signal from which, frequency equalizer A (L) becomes a summing point C (L) and then a stereo recorder guided. In the same way, the output signal from the right frequency equalizer A (R) is via a right Summing point C (R) to the stereo recorder guided.

130 616/0043

30AU29

In addition, the left stereo input signal from L (IN) is fed to an inverting device B (LB), which the phase of the signal at L (IN) is inverted by 180 °. The output signal from the inverting device B (LR) turns into 4 time delay friency equalizers via 4 channels transmitted, which are designated with b1 (LR), b2 (LR), b3 (LR) and b4 (LR), respectively. Any time delay frequency equalizer b1 (LR) to b4 (LR) has two functions, firstly the size of the inverted signal as a function of the To change frequency and secondly the signal by a given one Delay time measure. '

The collective or sum output from the 4 time delay frequency equalizers b1 (LR) to b4 (LR) reach a compensation signal that is sent to the right summing point C (R) is fed. This left-right stereo signal becomes the main right stereo signal from the right frequency equalizer A (R) is delivered, superimposed, this combined signal in turn to the stereo recorder is transmitted.

In the same way, the right stereo input signal at R (IN) is transmitted via an inverting device B (RL), that inverts the signal by 180 °. The output signal from inverting device B (RL) becomes a 2nd Satζ of 4 time delay equalizers via 4 channels transmitted, which are designated with b1 (RL), b2 (RL), b3 (RL) and b4 (RL). As with the other time delay frequency equalizers b1 (RL) '(correct: bl (LR)) to b4 (LR) it is a function of the 2nd set of the time delay frequency equalizers b1 (RL) to b4 (RL) to achieve a right-left compensation signal that goes to the left Summing point C (L) is transmitted. The compensation signal transmitted to the left summing point C (L) becomes the left main stereo output signal from the frequency

130616/0043

-Ho- 304U29

equalizer A (L) superimposed to achieve a combined signal that is also sent to the stereo recorder is transmitted.

In other respects the device according to FIG. 10 is in the essentially similar to the device according to FIG. 3, so that an explanation of the device according to FIG. 10 is no longer necessary is continued.

To explain the operation of the present invention reference is made to FIG. Assume that the sound recording made in the stereo recorder has been carried out by means of the device according to FIG. 10, now arranged in a stereo player which in turn is connected to 2 speakers LS and RS. The stereo player and the two speakers LS and RS can be conventional playback devices and loudspeakers as they are known in the prior art are. The playback device has the ability to pick up one of the signals on the sound recording and this to a loudspeaker LS for reproducing a sound related to the 1st signal, and the 2nd Record signal and send it to the other speaker RS lead to the generation of a 2nd sound, which corresponds to this 2nd signal. It follows without further ado that the sounds generated by the loudspeakers of FIG. 2 are essentially the same as the sound reproduced by the loudspeaker according to FIG. 3 so no further explanation thereof is added.
