Description

The present invention relates to sound reproducing devices for toys or the like and in particular a record that can be used for this purpose, on which various sequences of sounds or spoken texts in congruent spiral grooves are recorded.

Talking toys in which sound reproducing devices are used are known. Such a sound reproduction device, which is hidden in the toy, in the typical embodiment includes a disk-shaped one Record on which various spoken texts are recorded in separate tone grooves.

The record generally has an exposed or top surface with numerous congruent spiral grooves cut into run several turns. Each groove extends from an outer turn at a large distance from the center of the plate to an inner turn near the center of the plate. The device includes a tone arm with a needle that generates mechanical signals when it is in with a tone groove Is brought into contact and follows this groove as the record rotates in a selected direction, the is referred to as the playing direction. The mechanical signals are in an associated membrane to generate sound signals that represent the spoken text or sentence recorded in the groove and played by the needle. The tonearm is generally pressed against the record so that the needle follows one of the grooves.

The disk is generally "on a turntable on, which is mounted on a spindle or axis. A spring motor, generally a coiled coil spring, is connected to the axis. Manual controls, such as a pull cord, are also included with the axis tied together. When the cord is pulled out, the axle rotates in a first direction, thereby winding the spring will. The winding or pulling process is displayed by pulling the cord. Most of the previous When winding the cord, the cord is also used to pull the tonearm from an inner position, which is the

Tone arm assumes during playback to an outer position

pull, so that the needle with the outdoor coil of a groove in

Which it should follow during the following playback process. For this purpose, the cord is generally passed through or under the tone arm, so that the tone arm is first lifted from the record by pulling the cord, whereby the needle exposes the groove. By pulling the string further, the tonearm will pivot radially outward into its outer position. When the cord is released, which at the same time marks the beginning of a playback process, the tone arm can, since the cord is loose, be pressed against the record, whereby the needle engages in one of the grooves. At the same time, now that the cord is released, the spiral spring can unwind. As the spring unwinds, it rotates the axis and the turntable on which the record is located in a second or playback direction. During this rotation of the disk in the playback direction, one of the recorded language texts is played back.

In previous devices, various methods are used to select the texts to be played or sentences too primitive. Ir. some devices will use the Radial position of the tonearm at the beginning of the playback process controlled so that the tonearm one after the other the outer winding various spiral grooves detected, whereby the sentences are played back in a selected tone order.

In other devices, the turntable 30 is adjusted or rotated so that a desired surface portion of the disk is brought under the tone arm which is ready to play is so that the needle during playback is the outer turn that groove is detected which protrudes into the selected surface area of the record.

Previous devices of this latter type have the disadvantage that it is extremely difficult to the turntable set correctly so that the desired sentence is reproduced. These difficulties are mainly based on the fact that a large number of tone grooves are recorded on a small record. Therefore, the grooves are very close to each other and the turntable adjusting mechanism must be extraordinary be precise to make sure the selected groove is directly below the iTadel. One with this accuracy functioning mechanism is generally quite complicated and expensive and therefore unsuitable for Toys. What is required is a new type of record that can be made up by a simple mechanism adjuster, lets that the Uadel of a sound reproduction device can be conveniently brought into contact with any selected spiral groove on the plate.

The invention is based on the following task It is based on an improved record to be created in a sound reproduction device

-2.7.73

Toys or the like can be used.

A new type of record is also to be created on which different spoken texts are recorded separately Grooves are recorded, each of the grooves conveniently selectable from the one recorded therein Play text through a liadel.

It is also intended to provide a novel groove pattern on a record which can be used for sound reproduction devices can be created that simplify the disc adjustment with respect to the needle of a sound reproducing device appropriate tonearm in order to be able to select the sentence to be played.

Accordingly, the invention provides a record having a top surface that has an inner circular area contains, the outer edge of which has a certain distance from the center of the plate. All from several turns existing, concentric spiral grooves are located on this inner circular surface. The plate surface contains in addition, at least one hanging surface which extends from the outer edge of the circular surface to the outer edge of the plate. the Annular surface is divided into several sectors, each of which contains separate feed grooves leading to different ones Lead spiral grooves.

These and other features of the invention are provided explained in the following description in conjunction with the drawings.

Figure 1 is a plan view of a simplified representation of the record according to the invention.

Figure 2 is a plan view of a simplified representation of another embodiment of the invention.

FIGS. 3 and 4 show, as a plan view, further simplified representations of embodiments of the invention.

Consider now Figure 1, which is a plan view of an embodiment of the novel multi-groove record of the present invention and is designated by the reference numeral 10. The record has a top 12, to simplify the description in two main surface sections is divided. One section is an inner circular surface 14 which is formed by an outer annular surface 16 is surrounded. As FIG. 1 shows, this annular surface 16 is divided into six sectors S1-S6.

As is customary with the previous records for sound reproduction devices used in toys, the inner circular surface 14 contains numerous congruent spiral grooves. In the simplified embodiment shown here, the annular surface 16 of which contains only six sectors, the circular surface 14 also has only six spiral grooves G1-G6 Ί. Each of the spiral grooves should contain an outer turn on the outer edge of the circular surface 14 and an inner turn in the vicinity of the center point 20 of the plate 10. Preferably, all of the inner turns end through spiral grooves in a common inner groove 22. As in the previous one

Technique should each of the spiral grooves contain the recording of a sound sequence or a spoken text.

A tone arm 24 constitutes part of the sound reproduction apparatus in which the disk 10 is used. Of the Tonearm 24 is rotatably mounted on a pin 25 and contains a needle 30. As will be apparent to those skilled in the art, it follows the needle 30, when the disc 10 is rotated in the playback direction, that is in Figure 1 in the direction of arrow 32, one of the

Spiral grooves and generates mechanical signals, which in geeig i
Neten sound reproducing devices are converted into sound signals

and thereby the text recorded in the groove make audible.

'■ As has already been mentioned problems of the needle against selected portions arose in previous devices in the precise adjustment of the top 12, thereby select a desired text, that the needle is brought into contact with the right spiral groove. Up to now, the turntable had to be set very precisely and it had to be ensured that the needle 30 grasped the selected groove either before the playback or immediately at the start of the playback process. The accuracy required at this level complicates the sound reproducing apparatus and causes frequent malfunctions.

However, these problems are avoided by the novel record of the present invention by the different sectors (S1-S6) feed rillon

contain. The grooves of each sector are connected to one of the spiral grooves with the outer turn. as Initially, it is only required that one of the Feeding grooves of a sector which are connected to a selected spiral groove ir. At the beginning of the playback process can be grasped by the needle 30 ', whereby the needle 30 in desired 'tfuisc · in the outer 7 / indung of the selected Spiral groove is introduced.

correctly inserted into the outer turn of the spiral groove G1, if the needle 30 engages one of the feed grooves in sector S1.

As Figure 1 shows, each sector forms an arcuate one Main guide groove 34 running along the inner arc of the sector. Groove 34 forms in a smooth transition a continuation of the outer turn of the associated groove. Each sector also contains essentially two radially extending feed grooves 35 and 36, which are close to the radial limits of the

Sector should run. Each of the radial feed arrows is connected to the arcuate guide groove 34 of the sector.

From the above description in connection with Figure 1 , those skilled in the art will recognize that the correct

The needle position is then gcgcb-n when the plate 10 is rotated in this way

it is that the needle engages any groove within the area of a selected sector delimited by the grooves 34, 35 and 36. While the disk rotates in the playback direction, the needle is then inserted via one of the guide grooves into the outer turn of the spiral groove belonging to the sector. Y / ίε- Figure 1 shows, the needle 30 is connected to the feed channel 36 in the sector S1. In this case , when the disk 10 is rotated, the needle follows the feed groove 36 in the playback direction and arrives via the arcuate guide groove 34 to the outer winding of the spiral groove G1.

The needle would also then be guided into the correct spiral groove GI if it were in direct contact with one of the feed grooves. The needle should, for example, touch a surface area in the SI sector between the grooves 35 and 36. Wtnn the rotation of the disk starts in the play direction of the needle 30 from sliding ent speaking disk rotation in the feeding groove 35. With continued rotation of the disk to slide the needle into the groove 35 to the arc-shaped feed groove 34, which in the

outer turn of the spiral groove G1 transferred.

In summary of the foregoing description, the present invention provides a phonograph record a circular surface on which there are congruent spiral grooves which are each connected to a plurality of feed grooves in each one sector of an annular surface, the surrounds the circular surface bearing the spiral grooves. The feed grooves of each sector consist of an arcuate main guide groove and two radial feed grooves at the two opposite radial boundaries of the sector.

The number of radial feed grooves is not limited to the two radial boundary grooves. The surface between the radial feed grooves 35 and 36 of each sector expediently contains numerous further feed grooves which are identical with the grooves 35 and 36. Such additional grooves are represented in sector S4 by the reference numerals 41-45. Obviously, by increasing the number of radial feeder grooves in each sector - all of which communicate with the guide groove 34 of that sector, which in turn is a continuation of the outer turn of the spiral grooves - the likelihood of the needle entering the correct outer turn the desired spiral groove is inserted. In addition, by increasing the number of feed grooves, the plate can be adjusted with minimal angular rotation so that the needle engages a groove. This early

Groove can prove useful in those devices in which the tonearm 24 during the winding process in a is held in a fixed position, for example in the position indicated by dashed lines in Figure 1, the needle 30 resting on the surface 12 of the plate 10 before the plate is fully set. If there is no the groove 50 in such a device would produce an audible and perhaps annoying noise when the needle is on the surface 12 of the plate 10 rests, while this rests in the pulling direction (arrow 52) until the correct setting is rotated. The noise is generated by the repeated snapping of the needle 30 into the adjacent feed grooves. However, if the groove 50 is provided, the needle 30 runs in this groove until the correct setting is achieved without an annoying noise occurs.

-2.7.70

In such an arrangement, however, the tonearm must

be provided with a suitable train to the inside. This is necessary so that the needle running in the circular groove 50; is inserted guide grooves after the start of playback operation in one of the radial inflow _L, the groove 50 overlaps ^ to, in one of the Zufiihrungsrillen of that sector, which is located next to the needle, so that the desired selection of the recorded speech is ensured. For example, let the disk be set so that the tonearm is above sector S4 with needle 30 resting in groove 50 between feed grooves 42 and 43; the arn 24 mr. then had to be pretensioned inwards so that at the beginning of the playback the needle into one of the feeder grooves 42,

For this tensile stress springs, gravity or other means can be used, or one chooses the length and the pivot point of the tonearm, based on the Drehi.ttelpunkt of the plate, in the figure that an inwardly directed force component acts on the needle, which duroh Frictional forces are caused when the needle rubs across the plate surface independently of the grooves.

It is clear to experts that the probability to hit the right spiral to get the desired spoken text even with a somewhat imprecise depth setting the larger the sector and the larger the number of feeder

f grooves iat. In order to be able to take full advantage of the present invention, the sector should not be too small

Γ sain. If a large number of congruent spiral grooves are to be present on a single plate, according to the invention, in order not to fall below a suitable smallest sector size, instead of the one ring area shown in FIG inner circular area which contains the spiral grooves and which are each divided into sufficiently large sectors. A plate with two concentric annular surfaces is shown in FIG. 2, elements corresponding to those in FIG. 1 being denoted by the same reference numerals. The two concentric annular surfaces 16a and 16b each contain six sectors S1-S6. The sector associated with each spiral groove and the number of grooves provided on it is therefore sufficiently large.

If a plate with several ring surfaces is used, the required selection of the Speaking texts not only the record setting but also the deflection of the tonearm can be tracked. The position of the tonearm determines the ring surface with which the needle is brought into contact, thus making the selection of the desired one Ring surface, while the plate cladding selects a specific sector.

According to various embodiments according to the invention a plate is thus created that has numerous

Contains congruent spiral grooves. For each spiral groove is a sector of an annular surface is provided, dor several feed grooves contains, which are in communication with the outer turn of the spiral groove. With this arrangement, the The needle of an associated tonearm is inserted into the correct spiral groove if the sector associated with the groove is before the beginning is set correctly in relation to the needle

Spiral groove G2 shown in full; their starting point 61 is located at the end of the arcuate main guide groove 34, with which all feed grooves 35, 36 and 41-45 are in communication, and their end point is at 62. For illustration are different feed grooves for each of the spiral grooves G1 and G3 on both sides of the groove G2 as well as her respective start and end points 61 and 62 are also shown.

From the foregoing it will be apparent to those skilled in the art that the feed grooves can be positioned on both edge segments as desired as well as on segments near the center point. Such an embodiment is shown in Figure 4, The feed grooves of odd spiral grooves, such as G1, G3, etc., are located on surface segments near the outer edge of the plate, while the feed grooves for even spiral grooves on surface segments near the center of the plate are provided. In such an arrangement, the odd-numbered grooves (e.g. G3) end between the surface segments, which contains the feed grooves for the adjacent even spiral grooves & n (such as G2 and G4), while each the even-numbered grooves (about G4) on the plate edge in between ends the surface segments that form the feeder grooves for the two adjacent odd-numbered grooves (e.g. G3 and G5). However, this arrangement is only one of the various possible embodiments. For example the spiral grooves can be grouped together,

all of which are in the middle or on the edge of the plate. The sound sequences are evident or spoken texts of the spiral grooves, the feed grooves of which are on the edge of the plate, but only reproduced if the playing direction of the disc shown here is clockwise. For the reproduction of the spiral grooves, whose feed grooves are in the center of the plate, reverse plate rotation is required.

It will be apparent to those skilled in the art that changes and modifications can be made insofar as they come within the scope of the invention. For example, the ends of the spiral grooves do not necessarily have to end in a common groove 22, as FIG. 1 shows. According to Wunsoh, selected groups of spiral grooves can be stored in separate '■ ! End grooves.
