Description

Electronic devices and methods for controlling audio output and haptic motors in electronic devices

[0001] The present disclosure relates to a method for controlling audio output and haptic motor in an electronic device.

[0002] Portable electronic devices powered by batteries have become widespread in recent years. Batteries can have a variety of capacities. Small electronic devices may use relatively small batteries with small capacities, while large electronic devices may use large batteries with large capacities.

[0003] The capacity of batteries in portable electronic devices can be measured in mAh (or Ah), and a fully charged 1Ah battery can provide 1A of current for 1 hour. The current provided by the battery is called discharge, and the discharge rate of the battery can be defined as the C-rate. 1C can mean 1-hour discharge, while 0.5C can mean 2-hour discharge. For example, in a 100mAh battery, 1C can mean discharging the entire 100mA for 1 hour, and the C-value can be calculated by dividing the discharge current by the battery's rated capacity (the amount of current that can be used in 1 hour). Since the instantaneous current consumption can vary from device to device, batteries with different C-values ​​can be used for each electronic device.

[0004] Although batteries can provide more current at a time when their discharge rate is high, portable electronic devices (e.g., small electronic devices, wearable electronic devices, or smart watches) may use small batteries with relatively low maximum allowable discharge current values ​​due to the convenience of portability.

[0005] If the amount of current consumed instantaneously by an electronic device is greater than the amount of predefined (or set) discharge current (e.g., maximum allowable discharge current), the life of the battery may be shortened or heat generation may increase. Therefore, the amount of current consumed by an electronic device may need to be lowered below the amount of maximum allowable discharge current.

[0006] For example, in a small electronic device (e.g., a smartwatch) including a motor (e.g., a haptic motor) and a speaker, when a haptic motor driving operation and an audio output operation are performed simultaneously (or together), the amount of current consumed at one time may be greater than when the haptic motor driving operation and the audio output operation are performed separately, and may exceed the maximum allowable discharge current. In a small electronic device, when a haptic motor driving operation and an audio output operation need to be performed simultaneously (or together), and the amount of current consumed at one time is greater than the maximum allowable discharge current, a technique for reducing the amount of current consumed may be required.

[0007] When a haptic motor driving operation and an audio output operation must be performed simultaneously, the haptic motor driving operation and the audio output operation can be performed alternately in a time-division manner to reduce the amount of current consumed at one time. However, it may not be possible to adjust the sum of the current consumed by the instantaneous haptic motor driving operation and the current consumed by the audio output operation to be less than the maximum allowable discharge current.

[0008] According to an exemplary embodiment, an electronic device may include a battery, a haptic motor, a speaker, a haptic motor driving circuit, an audio circuit, at least one processor including a processing circuit, and a memory storing instructions. The at least one processor may be configured to individually and / or collectively execute the instructions, and cause the electronic device to output audio signals corresponding to audio data through the speaker using the audio circuit, identify audio signals to be output and haptic signals to be output based on haptic signals output simultaneously with the output of the audio signals through the speaker, estimate a discharge current value of the battery associated with the audio signals to be output simultaneously with the haptic signals to be output, and adjust a driving voltage for driving the haptic motor in association with a volume associated with the audio signals to be output and / or the haptic signals to be output, such that a discharge current value of the battery due to the output of the audio signals and the output of the haptic signals does not exceed the specified discharge current value when the estimated discharge current value exceeds a designated discharge current value.

[0009] In an exemplary embodiment, a method for controlling audio output and a haptic motor in an electronic device may include an operation of outputting audio signals corresponding to audio data through a speaker using an audio circuit, an operation of identifying audio signals to be output and haptic signals to be output based on haptic signals output simultaneously with the output of the audio signals through the speaker, an operation of estimating a discharge current value of the battery associated with the audio signals to be output simultaneously with the haptic signals to be output, and an operation of adjusting a volume associated with the audio signals to be output and / or a driving voltage for driving a haptic motor in association with the haptic signals to be output such that the discharge current value of the battery due to the output of the audio signals and the output of the haptic signals does not exceed the specified discharge current value based on the estimated discharge current value exceeding a specified discharge current value.

[0010] In an exemplary embodiment, a computer-readable non-transitory storage medium storing instructions, wherein the instructions are configured to cause the electronic device to perform at least one operation when individually and / or collectively executed by at least one processor of the electronic device, wherein the at least one operation may include: outputting audio signals corresponding to audio data through a speaker using an audio circuit; identifying audio signals to be output and haptic signals to be output based on haptic signals output simultaneously with the output of the audio signals through the speaker; estimating a discharge current value of the battery associated with the audio signals to be output simultaneously with the haptic signals to be output; and adjusting a volume associated with the audio signals to be output and / or a driving voltage for driving a haptic motor in association with the haptic signals to be output such that the discharge current value of the battery by the output of the audio signals and the output of the haptic signals does not exceed the designated discharge current value based on the estimated discharge current value exceeding a designated discharge current value.

When the haptic motor (479) is not driven, even if audio signals of the maximum peak volume (913) are output through the speaker (455), the maximum peak current value (923) of the discharge current (922) that is consumed (or discharged) may not exceed a predefined current value (955) (e.g., a maximum allowable discharge current value).

In a state where audio signals are not output, even if the haptic motor (479) is driven with maximum vibration, the maximum peak current value of the discharge current discharged (or consumed) may not exceed a predefined current value (955) (e.g., a maximum allowable discharge current value).

[0169] According to one embodiment, the processor (420) may clip the haptic motor driving voltage (1412) of the haptic motor driving circuit (478) as in the 15th graph (1410) to a haptic motor driving voltage limit value as in the 16th graph (1420) and apply the clipped haptic motor driving voltage (1422) to the haptic motor (479), thereby allowing the current consumed (or discharged) in the motor (479) to be less current consumed (1432) as in the 17th graph (1430).

[0171] FIG. 15 is a diagram for explaining an exemplary case of controlling a haptic motor driving voltage by using an inverted volume associated with audio signals to be output through a speaker when performing a haptic motor driving operation and an audio output operation according to various embodiments.

[0172] Referring to FIG. 15, a processor (420) according to an embodiment may obtain an inverted volume value (1512) of a volume value (912) associated with audio signals to be output through a speaker (455). A 19th graph (1510) according to an embodiment may be a graph representing an inverted volume value (1512) of a volume value (912) associated with audio signals to be output through a speaker (455).

[0173] According to one embodiment, the processor (420) may transmit a haptic motor driving control signal (or haptic control signal) to the haptic motor driving circuit (478) based on an inverted volume value (1512) of a volume value (912) associated with signals to be output through the speaker (455), so that the haptic motor (479) may use a current (1522) corresponding to an inverted volume value (1512) of a volume value (912) associated with audio signals to be output through the speaker (455), as in the 20th graph (1520).

[0174] According to one embodiment, a haptic motor driving control signal may be transmitted to a haptic motor driving circuit (478) as a first haptic control signal (e.g., 510 in FIG. 5) by waveform data through I2C (inter integrated circuit) communication or SPI (serial peripheral interface) communication, or as a second haptic control signal (e.g., 520 in FIG. 5) by audio data through I2S (inter IC (integrated circuit) sound) communication or TDM (time division multiplexing) communication.

[0176] FIG. 16 is a diagram illustrating an exemplary case of adjusting a predefined discharge current value in a battery performance degradation condition based on battery temperature according to various embodiments.

[0177] Referring to FIG. 16, the processor (420) according to one embodiment may use a predefined discharge current value (e.g., a specified maximum allowable discharge current value) (1610) in a normal mode (or a state in which a battery performance degradation condition based on battery temperature is not satisfied). The battery performance degradation condition based on battery temperature according to one embodiment may include a high temperature condition in which the temperature of the battery (489) is equal to or higher than a specified first temperature, and / or a low temperature condition in which the temperature of the battery (489) is lower than a specified second temperature. When the processor (420) according to one embodiment satisfies a high temperature condition in which the temperature of the battery (489) is equal to or higher than the specified first temperature, the processor (420) may change the predefined discharge current value (1610) to a first discharge current value (1620) that is lower by a specified first value than the predefined discharge current value (1610) and use it. According to one embodiment, the processor (420) can change the predefined discharge current value (1610) to a second discharge current value (1630) that is lower by a second value than the predefined discharge current value (1610) when the temperature of the battery (489) satisfies a low temperature condition that is lower than a second temperature.

[0178] According to one embodiment, the processor (420) may reduce the value of the discharge current of the battery (489) and / or control the value of the discharge current of the battery (489) not to exceed the first discharge current value (1620) or the second discharge current value (1630) when the haptic motor driving operation and the speaker output operation are performed together (or simultaneously) when the predefined discharge current value (1610) is changed to the first discharge current value (1620) or the second discharge current value (1630). For example, when the predefined discharge current value (1610) is changed to the first discharge current value (1620) or the second discharge current value (1630), the processor (420) may adjust the volume of audio signals and / or the haptic motor driving voltage to be lower by the ratio by which the predefined discharge current value is changed (lowered) when the haptic motor driving operation and the speaker output operation are performed together (or simultaneously), thereby preventing the value of the discharge current of the battery (489) from exceeding the first discharge current value (1620) or the second discharge current value (1630) when the haptic motor driving operation and the speaker output operation are performed together (or simultaneously).

[0179] FIG. 17 is a diagram illustrating an exemplary case of adjusting a predefined discharge current value in a battery performance degradation condition based on a battery voltage drop according to various embodiments.

[0180] Referring to FIG. 17, a processor (420) according to an embodiment may utilize a predefined discharge current value (1610) in a normal mode (or a state in which a battery performance degradation condition based on a battery voltage drop is not satisfied). The battery performance degradation condition based on a battery voltage drop according to an embodiment may be a case in which the battery voltage falls below a specified voltage depending on the current used within the electronic device (401) (or the system). In one embodiment, the processor (420) calculates a battery (489) DC resistance value (e.g., system (or load) voltage drop at the time of measurement / system (or load) current at the time of measurement) based on the battery voltage drop amount when the battery voltage falls below a specified voltage according to the current used inside (or in the system) of the electronic device (401), and obtains a third maximum allowable discharge current value (1720) (e.g., battery voltage drop allowable voltage value (e.g., voltage value at which the system can be stably operated without “Sudden power off” even if an additional voltage drop occurs based on the minimum voltage of the system Operation Range set in the electronic device (410) / battery DC resistance value) and changes a predefined discharge current value (1610) to the third discharge current value (1720) and uses it. For example, if the system operation minimum voltage set in the electronic device (410) is 3.5 V and the system stable operation minimum margin value is 3.2 V, the processor (420) can identify 3.5 V - 3.2 V = 0.3 V as the battery voltage drop allowable voltage value, and obtain a value obtained by dividing the battery voltage drop allowable value by the battery DC resistance value as the third discharge current value (1720).

[0181] In one embodiment, the processor (420) may control the discharge current of the battery (489) not to exceed the third discharge current value (1720) when the haptic motor driving operation and the speaker output operation are performed together (or simultaneously) when the predefined discharge current value (1610) is changed to the third discharge current value (1720). For example, the processor (420) may control the volume of audio signals and / or the haptic motor driving voltage to be lowered by the rate at which the predefined discharge current value is changed (lowered) when the haptic motor driving operation and the speaker output operation are performed together (or simultaneously) when the predefined discharge current value (1610) is changed to the third discharge current value (1720), thereby reducing the discharge current value of the battery (489) and / or preventing the discharge current value of the battery (489) from exceeding the third discharge current value (1720).

[0182] According to an exemplary embodiment, an electronic device and a method for controlling audio output and haptic motor in an electronic device can be provided, which can control the sum of current consumption by a haptic motor driving operation and current consumption by an audio output operation to be less than the size of a maximum allowable discharge current when a haptic motor driving operation and an audio output operation are to be performed simultaneously.
