Abstract

A haptic function control method for a portable terminal including a receipt-specific vibration motor that vibrates in a first frequency band and a haptic-specific vibration motor that vibrates in a second frequency band. At least one of the receipt-specific vibration motor and the haptic-specific vibration motor is driven based on a drive sampling frequency signal. The drive sampling frequency signal that vibrates the receipt-specific vibration motor and the haptic-specific vibration motor is determined from the first frequency band and the second frequency band.

Claims

1. A haptic function control method for a portable terminal including a receipt-specific vibration motor that vibrates in a first frequency band and a haptic-specific vibration motor that vibrates in a second frequency band, comprising:

driving at least one of the receipt-specific vibration motor and the haptic-specific vibration motor based on a drive sampling frequency signal,

wherein the drive sampling frequency signal that vibrates the receipt-specific vibration motor and the haptic-specific vibration motor is determined from the first frequency band and the second frequency band.

2. The method of claim 1, wherein the second frequency band is different from the first frequency band.

3. The method of claim 1, wherein when the receipt vibration motor and the haptic vibration motor vibrate simultaneously, the drive sampling frequency is a unitary vibration pattern set as a common multiple of the first frequency band and the second frequency band.

4. The method of claim 1, wherein the first frequency band is approximately 160 Hz through 190 Hz and the second frequency band is approximately 320 Hz through 450 Hz.

5. The method of claim 4, wherein the vibration frequency of the receipt-specific vibration motor is approximately 170 Hz.

6. The method of claim 1, wherein the haptic-specific vibration motor includes one of a linear motor or a piezoelectric motor.

7. A portable terminal for providing a haptic function comprising:

a receipt-specific vibration motor that vibrates in a first frequency band;

a haptic-specific vibration motor that vibrates in a second frequency band; and

a controller for driving at least one of the receipt-specific vibration motor and the haptic-specific vibration motor based on a drive sampling frequency signal,

wherein the drive sampling frequency signal is determined from the first frequency band and the second frequency band.

8. The portable terminal of claim 7, wherein the second frequency band is different from the first frequency band.

9. The portable terminal of claim 7, wherein when the receipt vibration motor and the haptic vibration motor vibrate simultaneously, the drive sampling frequency comprises a unitary vibration pattern set as a common multiple of the first frequency band and the second frequency band.

10. The portable terminal of claim 7, wherein the first frequency band is a range comprising approximately 160 Hz through 190 Hz and the second frequency band is a range comprising approximately 320 Hz through 450 Hz.

11. The portable terminal of claim 10, wherein the vibration frequency of the receipt-specific vibration motor is approximately 170 Hz.

12. The portable terminal of claim 7, wherein the haptic-specific vibration motor comprises one of:

a linear motor; and

a piezoelectric motor.
