Description

The present invention relates to a turntable, and more particularly, to a voice identification turntable that can be identified by voice and automatically faces a sound source.

A conventional turntable is, for example, a turntable for a store to display products, and it mainly puts the product on the turntable and shows the product displayed by the movement of the turntable to consumers. Has an aim. However, the rotary table for the product has only a simple rotating function and does not have any additional function, so that the function is not ideal.

Furthermore, there is a dog toy in the industry that walks toward the sound source when a sound is heard, but when the sound source is detected, the turntable turns toward the sound source. It does not have such a function. Like the present invention, the dog toy is not practical because it is not possible to have fun by installing a doll or a theme object on the turntable.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a structure of a voice identification turntable that can rotate a turntable so as to face the direction of a sound source when the sound source direction is detected.

To achieve the above object, the present invention comprises a turntable, a body case, and a drive unit. The main body case is provided below the turntable, and the main body case includes a plurality of sound sensors. The drive unit is provided in the main body case, and the drive unit includes a control circuit, a drive circuit, a motor, and a drive mechanism, of which the control circuit includes a voice identification module and the drive circuit. And the drive circuit is connected to the motor, the motor links the drive mechanism, and the drive mechanism links the turntable. The sound sensor collects sounds at corresponding angles, converts the sound into a voice signal, transmits the voice signal to the voice identification module, and further, based on the voltage level of the voice signal, the maximum volume of the sound sensor. Is further identified, and further, the drive circuit drives the motor shaft to rotate in one direction according to a command of a predetermined corresponding parameter, thereby interlocking the drive mechanism and the turntable, and , Rotating the angle of the turntable so as to face the sound sensor collecting the maximum volume of sound.

In the present invention, when the sound source is detected, the turntable can be rotated so as to face the direction of the sound source.

The present invention also makes it possible to install a doll on the turntable, so that the theme object has fun and practicality.

FIG. 7 is a perspective view of another embodiment of the present invention.

As shown in FIGS. 1 to 4 to be referred to, the present invention includes a turntable 10, a main body case 20, and a drive unit 30. This will be described in detail below.

The body case 20 is provided below the turntable 10, and the body case 20 includes a plurality of sound sensors 21. In the present embodiment, three sound sensors 21 are provided, but the number is not limited to this.

The drive unit 30 is provided in the main body case 20, and the structure of the drive unit 30 includes a control circuit 31, a drive circuit 32, a motor 33, and a drive mechanism 34, of which the control circuit 31. Is provided with a voice identification module (not shown) and is connected to the drive circuit 32, the drive circuit 32 is connected to the motor 33, and the motor 33 causes the drive mechanism 34 to interlock with each other. 34 interlocks the turntable 10.

The sound sensor 21 collects sounds at corresponding angles, converts the sound into a sound signal, and transmits the sound signal to the sound identification module. Based on the voltage of the sound signal, the sound sensor 21 outputs the maximum sound volume. Sound is identified, and further, the drive circuit 32 drives the shaft of the motor 33 to rotate in one direction in accordance with a command of a predetermined corresponding parameter, thereby causing the drive mechanism 34 and the turntable 10 to rotate. Further, the angle of the turntable 10 is rotated so as to face the direction of the sound sensor 21 that collects the maximum volume of sound.

According to the present invention, when a sound source is detected, the turntable 10 can be rotated so as to face the sound source.

Further, it should be explained that when the sound sensor 21 starts to receive a sound, the determination is performed based on the sound received first, and when the control circuit 31 receives the determined position, the motor 33 is rotated. , No sound is received while the motor 33 rotates, that is, no sound is received until the set position is reached, and the sound is received again after the motor 33 has finished rotating to the determined position. That is, when the motor 33 is energized and the turntable 10 is driven and rotated, no sound is received within the time, and the control circuit 31 temporarily sets the length of time during which no sound is received. Can be detected.

In the embodiment, the plurality of sound sensors 21 are arranged on the circumference according to 0 degrees, 120 degrees, and 240 degrees, and face different directions.

In the embodiment, the main body case 20 includes a housing 22, a pedestal 23, and a power supply cover 24, and each sound sensor 21 of the housing 22 is provided with a plurality of openings 221. As the sound passes through the opening 221, the sound sensor 21 can effectively collect the sound, the pedestal 23 is provided with the speaker 231, and the power supply cover 24 is removable. The motor 33 can be powered by being able to insert a battery from the power cover 24.

In the embodiment, the drive unit 30 includes a plurality of housing portions 35, the plurality of housing portions 35 correspond to the plurality of sound sensors 21, and each of the housing portions 35 is provided with a positioning switch 36. The positioning switch 36 is electrically connected to the drive circuit 32 and the motor 33. A drive shaft 37 is provided on the output shaft 341 of the drive mechanism 34, and the drive shaft 37 includes a protrusion 371. When the drive mechanism 34 rotates the output shaft 341, the drive shaft 37 is moved. The rotation of the drive circuit 32 and the motor 33 by turning the projection 371 into contact with the positioning switch 36 and cutting off the power supply to the drive circuit 32 and the motor 33. The drive of the turntable 10 is stopped.

Therefore, when the turntable 10 is rotated by the motor 33 and the angle of the turntable 10 faces the direction of the sensor 21 that collects the maximum volume of sound, the rotation is automatically and immediately stopped and the turntable 10 does not rotate. Further, when the angle of the turntable 10 moves, the turntable 10 can be reliably positioned.

In the embodiment, the drive mechanism 34 is a reduction gear set.

As shown in FIG. 5 to be referred to, in the embodiment, the turntable 10 may be provided with either a doll or a theme item.

In the present embodiment, the turntable 10 is provided with an animal-shaped ornamental doll "Maneki Neko 40", and a theme object is displayed. When the turntable 10 rotates to the direction of the sound source where the sound is generated, the hand automatically shakes, which is interesting and practical.
