[0004] A wearable device is described. In one embodiment, the wearable device may include at least one processor comprising a memory storing instructions and including one or more storage media, a speaker, and a processing circuit. The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to detect an emergency condition of a user.

[0023] Hereinafter, various embodiments of the present disclosure will be described in more detail with reference to the drawings. However, the present disclosure may be implemented in various different forms and is not limited to the embodiments described herein. In connection with the description of the drawings, the same or similar reference numerals may be used for identical or similar components. Furthermore, in the drawings and related descriptions, descriptions of well-known functions and configurations may be omitted for clarity and conciseness.

[0024] FIG. 1 is a diagram illustrating examples of audio corresponding to emergency sirens provided based on emergency conditions according to various embodiments.

[0025] Referring to FIG. 1, a wearable device (100) may be described as a device for providing audio corresponding to an emergency siren. For example, the wearable device (100) may be used to detect an emergency state of a user (110) wearing the wearable device (100). For example, and without limitation, the wearable device (100) may be implemented in various forms that can be worn by a user, such as a smart watch, a smart band, a smart ring, wireless earphones, smart glasses, or the like, including circuits (or circuitry) for providing audio corresponding to an emergency siren. In the following disclosure, for the convenience of explanation, an example in which the wearable device (100) is formed in the form of a watch will be described, and it will be understood that the present disclosure is not limited thereto.

[0026] For example, state (105) may be described as an emergency state of the user (110). For example, within state (105), the wearable device (100) may detect an emergency state of the user (110). For example, the emergency state of the user (110) may include an accident situation of the user (110) (e.g., a fall situation).

[0027] For example, the wearable device (100) may include a speaker (115). For example, the speaker (115) may be used to provide audio corresponding to an emergency siren. For example, the wearable device (100) may provide audio corresponding to an emergency siren based on the emergency state of the user (110). For example, the wearable device (100) may output an audio signal (120) through the speaker (115) to provide audio corresponding to an emergency siren. The audio signal (120) for providing audio corresponding to an emergency siren is illustrated and described in more detail with reference to FIG. 2 below.

[0028] FIG. 2 is a diagram illustrating an example of an audio signal for providing audio corresponding to an emergency siren according to various embodiments.

[0029] Referring to FIG. 2, the chart (200) represents changes in sound pressure of audio signals (215-1, 215-2) over time. The horizontal axis (205) in the chart (200) represents time, and the vertical axis (210) in the chart (200) represents the sound pressure of the audio signals (215-1, 215-2).

[0030] For example, the sound pressure of an audio signal (215-1, 215-2) can be expressed as the vertical length of an object corresponding to the audio signal (215-1, 215-2) in the chart (200).

[0031] For example, the wearable device (100) may output an audio signal (215-1) through a speaker (e.g., the speaker (115) of FIG. 1) to provide audio corresponding to an emergency siren based on the emergency state of a user (e.g., the user (110) of FIG. 1). For example, the wearable device (100) may output the audio signal (215-1) to notify the user of the emergency state. For example, the audio signal (215-1) may be output as a sound pressure (220). For example, in order to effectively notify the user of the emergency state, it may be required to output an audio signal with a relatively large sound pressure. For example, the sound pressure (220) may correspond to a full-scale sound pressure. For example, the wearable device (100) can effectively notify the user of an emergency state by outputting an audio signal (215-1) at a sound pressure (220) corresponding to full-scale sound pressure.

[0032] For example, the wearable device (100) may output an audio signal (215-1) for a time period (225). For example, the wearable device (100) needs to output the audio signal (215-1) for a sufficiently long time period to notify the user of an emergency condition. For example, the wearable device (100) may output the audio signal (215-1) at a sound pressure (220) corresponding to full-scale sound pressure for a sufficiently long time period (225), thereby increasing the heat generation of the speaker. For example, the speaker may be damaged due to the increased heat generation of the speaker. For example, the user may feel discomfort due to the heat generation of the speaker.

[0033] For example, in order to reduce the heat generation of the speaker, the wearable device (100) may stop (or refrain from, or not output) the output of the audio signal (215-1) for a time period (230). For example, in order to effectively reduce the heat generation of the speaker, the wearable device (100) may be required to stop outputting the audio signal (215-1) for a relatively long time period (230) after outputting the audio signal (215-1). For example, the wearable device (100) may not be able to effectively notify the user of an emergency condition by stopping (or refraining from, or not outputting) the output of the audio signal (215-1) for a relatively long time period (230). For example, in order to effectively notify the user of an emergency condition, the wearable device (100) needs to reduce the time period (230) for which it stops outputting the audio signal (215-1). For example, a method may be required to reduce the time interval (230) for stopping the output of an audio signal (215-1). For example, in order to reduce the time interval (230) for stopping the output of an audio signal (215-1), the wearable device (100) may reduce the heat generation of the speaker generated by outputting the audio signal (215-1).

[0034] For example, the wearable device (100) can reduce the time interval (230) for stopping the output of the audio signal (215-1) by reducing the heat generation of the speaker. For example, the wearable device (100) can effectively notify the user of an emergency state by reducing the time interval (230) for stopping the output of the audio signal (215-1). For example, the wearable device (100) can reduce damage to the speaker or alleviate user discomfort caused by the heat generation of the speaker by reducing the heat generation of the speaker.

[0035] For example, in order to reduce heat generation of the speaker, the wearable device (100) may output another audio signal with a sound pressure lower than the sound pressure (220) before outputting the audio signal (215-1). For example, the wearable device (100) may output the audio signal (215-1) for a time period shorter than the time period (225) after outputting the other audio signal, thereby reducing heat generation of the speaker.

[0036] The wearable device (100) may perform operations, which will be illustrated and described in more detail with reference to FIGS. 4 to 8 below, to reduce heat generation of the speaker. The wearable device (100) may include components for performing the operations. The components may be illustrated and described in more detail with reference to FIG. 3 below.

[0037] FIG. 3 is a block diagram illustrating an exemplary configuration of a wearable device according to various embodiments.

[0038] Referring to FIG. 3, the wearable device (300) may be implemented in various forms that can be worn by a user, for example, and without limitation, a smart watch, a smart band, a smart ring, wireless earphones, smart glasses, or the like. Hereinafter, in the present disclosure, for the convenience of explanation, an example in which the wearable device (300) is formed in the form of a watch will be described. For example, the wearable device (300) may include the wearable device (100) of FIG. 1 or correspond to the wearable device (100) of FIG. 1. For example, the wearable device (300) may include at least a portion of the electronic device (1104) of FIG. 11 or correspond to at least a portion of the electronic device (1104) of FIG. 11. For example, a wearable device (300) may include at least one processor (310) (e.g., including a processing circuit), memory (320), and speaker (330).

[0039] At least one processor (310) may include processing circuitry. For example, at least one processor (310) may include a central processing unit (CPU) (e.g., including processing circuitry). For example, at least one processor (310) may include a graphics processing unit (GPU) (e.g., including processing circuitry) and / or a neural processing unit (NPU) (e.g., including processing circuitry). For example, at least one processor (310) may be described as an application processor. For example, at least one processor (310) may be configured to control the memory (320) and the speaker (330). At least one processor (310) may be configured to individually or collectively execute instructions stored in the memory (320) to cause the wearable device (300) to perform at least some of the operations illustrated and described with reference to FIGS. 1 and 2 . At least one processor (310) may be configured to execute instructions stored in the memory (320) to cause the wearable device (300) to perform at least some of the operations illustrated in the descriptions of FIGS. 4 through 8. For example, the term "processor" as used herein, including in the claims, may include various processing circuits including at least one processor, one or more of which may be configured to individually and / or collectively perform the various functions described below in a distributed manner.As used herein, when "processor," "at least one processor," and "one or more processors" are described as being configured to perform various functions, these terms encompass, for example and without limitation, situations where one processor performs some of the recited functions and other processor(s) perform other parts of the recited functions, and also situations where one processor can perform all of the recited functions. Additionally, the at least one processor may comprise a combination of processors that perform the various functions enumerated / disclosed, for example, in a distributed manner. At least one processor may execute program instructions to achieve or perform the various functions.

[0040] The memory (320) may include one or more storage media. For example, the memory (320) may store various data used by at least one component of the wearable device (300) (e.g., at least one processor (310) and a speaker (330)). For example, the data may include input data or output data for software and commands related thereto. The memory (320) may include volatile memory or non-volatile memory.

[0041] The speaker (330) may be configured to output an audio signal. For example, the speaker (330) may correspond to the speaker (115) of FIG. 1. For example, the speaker (330) may be configured to output an audio signal to provide audio corresponding to an emergency siren.

[0042] The wearable device (300) illustrated in the description of FIG. 3 may execute at least some of the operations that will be illustrated and described in more detail with reference to FIGS. 4 to 8 below. For example, the operations illustrated in the description of FIGS. 4 to 8 may be caused by (or within) the wearable device (300) under the control of at least one processor (310).

[0043] FIG. 4 is a flowchart illustrating exemplary operations of a wearable device for providing audio corresponding to an emergency siren, according to various embodiments.

[0044] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0045] Referring to FIG. 4, in operation 400, at least one processor (310) may detect an emergency state of a user (e.g., the user (110) of FIG. 1). For example, the emergency state of the user may include an accident situation of the user (e.g., a fall situation).

[0046] As a non-limiting example, the wearable device (300) may further include sensors (e.g., an acceleration sensor, a gyro sensor, a photoplethysmography (PPG) sensor, a barometric pressure sensor, and / or an electrode sensor). For example, at least one processor (310) may detect an emergency state of the user based on biometric information of the user acquired through the sensors.

[0047] As a non-limiting example, at least one processor (310) may receive an input indicating that the user is in an emergency state. For example, the input may be provided by an input means (e.g., a button) of the wearable device (300). For example, the input may be provided through a display (e.g., a touchscreen) of the wearable device (300). For example, at least one processor (310) may detect an emergency state of the user based on the input. However, the present invention is not limited thereto.

[0048] As a non-limiting example, the wearable device (300) may be described as a virtual reality (VR) device and / or an augmented reality (AR) device. For example, at least one processor (310) may provide a virtual space. For example, at least one processor (310) may detect that a user is in an emergency situation outside of the virtual space. For example, at least one processor (310) may provide audio corresponding to an emergency siren based on the user's emergency situation outside of the virtual space. However, the present invention is not limited thereto.

[0049] As a non-limiting example, the wearable device (300) may further include a communication circuit. For example, the wearable device (300) may establish a connection with an external electronic device using the communication circuit. For example, the external electronic device may receive an input indicating that the user is in an emergency state while connected to the wearable device (300). For example, the external electronic device may transmit a signal to cause the wearable device (300) to execute a function for the user's emergency state based on the input. For example, at least one processor (310) may receive the signal from the external electronic device via the communication circuit. For example, at least one processor (310) may detect the user's emergency state based on the signal. However, the present invention is not limited thereto.

[0050] In operation 410, at least one processor (310) may provide audio corresponding to an emergency siren based on the user's emergency state. For example, to provide audio corresponding to an emergency siren, at least one processor (310) may output a first audio signal (e.g., the first audio signal (515-1) of FIG. 5A) in a first frequency range at a first sound pressure (e.g., the first sound pressure (520) of FIG. 5A) through a speaker (330).

[0051] In operation 420, at least one processor (310) may output a second audio signal (e.g., the second audio signal (530-1) of FIG. 5A) in a second frequency range with a second sound pressure (e.g., the second sound pressure (535) of FIG. 5A) through the speaker (330) to provide audio corresponding to an emergency siren. For example, the second sound pressure may be greater than the first sound pressure. For example, the second frequency range may have a higher audible sensitivity than the audible sensitivity of the first frequency range.

[0052] The first audio signal and the second audio signal are illustrated and described in more detail with reference to FIG. 5a below.

[0053] FIG. 5A is a diagram illustrating examples of audio signals corresponding to emergency sirens according to various embodiments.

[0054] Referring to FIG. 5A, a chart (500) represents changes in sound pressure of an audio signal (e.g., a first audio signal (515-1) and a second audio signal (530-1)) over time. The horizontal axis (505) in the chart (500) represents time, and the vertical axis (510) in the chart (500) represents the sound pressure of the audio signal.

[0055] For example, the sound pressure of an audio signal can be expressed as the vertical length of an object corresponding to the audio signal in the chart (500).

[0056] For example, at least one processor (310) may output a first audio signal (515-1) through the speaker (330) to provide audio corresponding to an emergency siren based on an emergency state of a user (e.g., the user (110) of FIG. 1). For example, the first audio signal (515-1) may be output on a first frequency range. For example, the first frequency range may be defined as a frequency range in which the first audio signal (515-1) is output with the greatest sound pressure among the frequency ranges in which the first audio signal (515-1) is output.

[0057] For example, at least one processor (310) may output a first audio signal (515-1) to burn-in (or age, or break-in) the speaker (330).

[0058] For example, at least one processor (310) may output the first audio signal (515-1) for a relatively short first time interval (525) by outputting the first audio signal (515-1) to burn-in (or age, or break-in) the speaker (330). For example, at least one processor (310) may output the first audio signal (515-1) for a relatively short first time interval (525) by outputting the first audio signal (515-1) to burn-in (or age, or break-in) the speaker (330), thereby outputting the first audio signal (515-1) at a first sound pressure (520) that is a relatively small sound pressure. For example, by outputting the first audio signal (515-1) at a first sound pressure (520) that is a relatively small sound pressure, heat generation of the speaker (330) may be relatively low.

[0059] For example, the speaker (330) may be burned in (or aged, or broken in) as it outputs the first audio signal (515-1). For example, the resonant frequency of the speaker (330) may change from the first resonant frequency to the second resonant frequency as the speaker (330) is burned in (or aged, or broken in). For example, the second resonant frequency may be lower than the first resonant frequency. The resonant frequency of the speaker (330) as it outputs the first audio signal (515-1) is illustrated and described in more detail with reference to FIG. 6 below.

[0060] FIG. 6 is a graph showing examples of resonant frequencies of speakers according to various embodiments.

[0061] Referring to FIG. 6, a graph (600) represents a change in the maximum sound pressure of an audio signal that can be output through a speaker (330) according to frequency. The horizontal axis (605) in the chart (600) represents the frequency of the audio signal, and the vertical axis (610) in the chart (600) represents the maximum sound pressure of an audio signal that can be output through the speaker (330).

[0062] For example, the maximum sound pressure of an audio signal that can be output through the speaker (330-1) in the first state before outputting the first audio signal (e.g., the first audio signal (515-1) of FIG. 5A) can be expressed as a line (615). For example, the maximum sound pressure of an audio signal that can be output through the speaker (330-1) in the first state can be represented as a first sound pressure (625) at a first frequency (620). For example, the first sound pressure (625) can be a maximum value of the maximum sound pressure of an audio signal that can be output through the speaker (330-1) in the first state. For example, the speaker (330-1) in the first state can have the first frequency (620) as a resonant frequency by having the first sound pressure (625) as the maximum sound pressure of an audio signal that can be output at the first frequency (620). For example, the speaker (330-1) in the first state can output an audio signal with a relatively large sound pressure at the first frequency (620) by having the first frequency (620) as a resonant frequency.

[0063] For example, the speaker (330) may be burned in (or aged, or broken in) as it outputs the first audio signal. For example, the state of the speaker (330) may change from a first state to a second state as the speaker (330) is burned in (or aged, or broken in).

[0064] For example, the maximum sound pressure of an audio signal that can be output through the speaker (330-2) in the second state after outputting the first audio signal may be expressed as a line (630). For example, the maximum sound pressure of an audio signal that can be output through the speaker (330-2) in the second state may be represented as a second sound pressure (640) at a second frequency (635). For example, the second sound pressure (640) may be a maximum value of the maximum sound pressure of an audio signal that can be output through the speaker (330-2) in the second state. For example, the speaker (330-2) in the second state may have the second frequency (635) as a resonant frequency by having the second sound pressure (640) as the maximum sound pressure of an audio signal that can be output at the second frequency (635). For example, the speaker (330-2) in the second state can output an audio signal with a relatively large sound pressure at the second frequency (635) by having the second frequency (635) as a resonant frequency.

[0065] For example, the second frequency (635) may be lower than the first frequency (620) by the difference (645) between the second frequency (635) and the first frequency (620). For example, the resonant frequency of the speaker (330) may be lowered as the speaker (330) changes from the first frequency (620) to the second frequency (635) by burning in (or aging, or break-in). For example, the speaker (330-2) in the second state (or the burnt-in speaker) may output audio data with a relatively large sound pressure on the second frequency (635) lower than the first frequency (620). For example, at least one processor (310) may output audio data with a relatively large sound pressure on a relatively low frequency band by burning in (or aging, or break-in) the speaker (330). For example, at least one processor (310) can effectively notify the user of an emergency condition by outputting an audio signal through a burnt-in (or aged, or broken-in) speaker (330).

[0066] Referring back to FIG. 5A, at least one processor (310) may output a first audio signal (515-1) and then output a second audio signal (530-1) through a burn-in (or aged, or break-in) speaker (e.g., the second state speaker (330-2) of FIG. 6). For example, the second audio signal (530-1) may be output with a second sound pressure (535) greater than the first sound pressure (520). For example, the second sound pressure (535) may correspond to a full-scale sound pressure. For example, the at least one processor (310) may output the second audio signal (530-1) with a second sound pressure (535) corresponding to a full-scale sound pressure in order to effectively notify the user of an emergency state.

[0067] For example, the second audio signal (530-1) can be output on a second frequency range having a higher audible sensitivity than the audible sensitivity of the first frequency range of the first audio signal (515-1). For example, the second frequency range can be defined as a frequency range in which the second audio signal (530-1) is output with the greatest sound pressure among the frequency ranges in which the second audio signal (530-1) is output. For example, a frequency range having a high audible sensitivity can be defined as a frequency range of audio that is effectively audible to the human ear (e.g., a frequency range from 3 kilohertz (kHz) to 4 kHz). For example, when the speaker (330) is burned in (or aged, or broken in) according to the output of the first audio signal (515-1), the burned-in speaker can have a second resonant frequency (e.g., the second resonant frequency (635) of FIG. 6). For example, since the burnt-in speaker has a second resonant frequency, the burnt-in speaker can output an audio signal with a relatively high sound pressure in a second frequency range having a relatively high audible sensitivity. For example, at least one processor (310) can effectively notify a user of an emergency state by outputting a second audio signal (530-1) through the burnt-in speaker.

[0068] For example, at least one processor (310) can effectively notify the user of an emergency condition by outputting the second audio signal (530-1) with a relatively high sound pressure in a second frequency range having a relatively high audible sensitivity, even if the second audio signal (530-1) is output for a relatively short second time interval (540). For example, at least one processor (310) can output the second audio signal (530-1) for a relatively short second time interval (540), so that relatively low heat generation of the speaker (330) can occur. For example, since the speaker (330) generates relatively low heat generation, damage to the speaker (330) can be reduced, or discomfort to the user can be resolved. For example, since the speaker (330) generates relatively low heat generation, the battery of the wearable device (300) can be discharged relatively slowly.

[0069] For example, in order to reduce heat generation of the speaker (330), at least one processor (310) may stop (or refrain from, or not output) outputting the audio signal after outputting the second audio signal (530-1), or may output the third audio signal at a third sound pressure lower than the first sound pressure (520). For example, at least one processor (310) may stop (or refrain from, or not output) outputting the audio signal during a third time period (545) that is relatively shorter than the time period (230) of FIG. 2, or may output the third audio signal at a third sound pressure lower than the first sound pressure (520), depending on relatively low heat generation. For example, at least one processor (310) can effectively notify the user of an emergency state by stopping (or refraining from, or not outputting) an audio signal during a third time interval (545) that is relatively shorter than the time interval (230) of FIG. 2, or by outputting a third audio signal at a third sound pressure that is lower than the first sound pressure (520).

[0070] For example, at least one processor (310) may output a fourth audio signal (515-2) through the speaker (330) after a reference time has elapsed after outputting a second audio signal (530-1). For example, the fourth audio signal (515-2) may correspond to the first audio signal (515-1).

[0071] For example, at least one processor (310) may output a fourth audio signal (515-2) and then output a fifth audio signal (530-2) through the burnt-in (or aged, or broken-in) speaker in response to outputting the fourth audio signal (515-2). For example, the fifth audio signal (530-2) may correspond to the second audio signal (530-1).

[0072] For example, at least one processor (310) can repeatedly output a first audio signal (515-1) and a second audio signal (530-1) through the speaker (330) according to a specified cycle. For example, the first audio signal (515-1) and the second audio signal (530-1) can constitute one section or one segment.

[0073] For example, at least one processor (310) can repeatedly output the first audio signal (515-1), the second audio signal (530-1), and the third audio signal through the speaker (330) according to a specified cycle. For example, the specified cycle may include one cycle during the fourth time interval (550). For example, at least one processor (310) can effectively notify the user of an emergency state by repeatedly outputting the first audio signal (515-1), the second audio signal (530-1), and the third audio signal through the speaker (330) according to a specified cycle. For example, at least one processor (310) can effectively provide audio corresponding to an emergency siren by repeatedly outputting the first audio signal (515-1), the second audio signal (530-1), and the third audio signal through the speaker (330) according to a specified cycle.

[0074] For example, at least one processor (310) may detect that the user's emergency state has ended while providing the audio corresponding to the emergency siren. For example, at least one processor (310) may stop (or refrain from, or not output) the output of the first audio signal (515-1), the second audio signal (530-1), and / or the third audio signal based on the termination of the emergency state.

[0075] FIG. 5b is a diagram illustrating examples of audio signals corresponding to an emergency siren according to various embodiments.

[0076] Referring to FIG. 5b, a chart (555) illustrates changes in sound pressure of audio signals (e.g., a first audio signal (570-1), a second audio signal (578-1), and a third audio signal (580-1)) over time. The horizontal axis (560) in the chart (555) represents time, and the vertical axis (565) in the chart (555) represents the sound pressure of the audio signals.

[0077] For example, the sound pressure of an audio signal can be expressed as the vertical length of an object corresponding to the audio signal in the chart (555).

[0078] For example, at least one processor (310) may output a first audio signal (570-1) through the speaker (330) to provide audio corresponding to an emergency siren based on an emergency state of a user (e.g., the user (110) of FIG. 1). For example, the first audio signal (570-1) may be output on a first frequency range. For example, the first frequency range may be defined as a frequency range in which the first audio signal (570-1) is output with the greatest sound pressure among the frequency ranges in which the first audio signal (570-1) is output. For example, the first audio signal (570-1) may be output in a sweeping manner on the first frequency range.

[0079] For example, at least one processor (310) may output a first audio signal (570-1) and then output a second audio signal (578-1) through the speaker (330). For example, the second audio signal (578-1) may correspond to the first audio signal (515-1) of FIG. 5A. For example, the second audio signal (578-1) may be output on a first frequency range.

[0080] For example, at least one processor (310) may output a first audio signal (570-1) and a second audio signal (578-1) to burn-in (or age, or break-in) the speaker (330).

[0081] For example, at least one processor (310) may output the first audio signal (570-1) and the second audio signal (578-1) for a relatively short first time interval (577) and a second time interval (579) by outputting the first audio signal (570-1) and the second audio signal (578-1) to burn-in (or age, or break-in) the speaker (330). For example, at least one processor (310) may output the first audio signal (570-1) and the second audio signal (578-1) at a relatively small sound pressure by outputting the first audio signal (570-1) and the second audio signal (578-1) to burn-in (or age, or break-in) the speaker (330).

[0082] For example, at least one processor (310) may output the first audio signal (570-1) at a first sound pressure, which is a relatively small sound pressure. For example, the first sound pressure may gradually increase within a range from the second sound pressure (575) to the third sound pressure (576). For example, the second sound pressure (575) may be lower than the third sound pressure (576). For example, by having at least one processor (310) output the first audio signal (570-1) at the first sound pressure, which is a relatively small sound pressure, the heat generation of the speaker (330) may be relatively low.

[0083] For example, at least one processor (310) can output the second audio signal (578-1) at a third sound pressure (576), which is a relatively small sound pressure. For example, by having at least one processor (310) output the second audio signal (578-1) at a third sound pressure (576), which is a relatively small sound pressure, the heat generation of the speaker (330) can be relatively low.

[0084] For example, at least one processor (310) may burn-in (or age, or break-in) the speaker (330) by outputting a first audio signal (570-1) and a second audio signal (578-1). For example, the description of FIG. 6 may be referred to for the burn-in (or age, or break-in) of the speaker (330).

[0085] For example, at least one processor (310) may output a second audio signal (578-1) and then output a third audio signal (580-1) through a burnt-in (or aged, or broken-in) speaker (e.g., the second state speaker (330-2) of FIG. 6). For example, the third audio signal (580-1) may correspond to the second audio signal (530-1) of FIG. 5A.

[0086] For example, the third audio signal (580-1) may be output with a fourth sound pressure (581) that is greater than the third sound pressure (576). For example, the fourth sound pressure (581) may correspond to a full-scale sound pressure. For example, at least one processor (310) may output the third audio signal (580-1) with a fourth sound pressure (581) that corresponds to a full-scale sound pressure in order to effectively notify the user of an emergency condition.

[0087] For example, the third audio signal (580-1) may be output on a second frequency range having a higher audible sensitivity than the audible sensitivities of the first frequency ranges of the first audio signal (570-1) and the second audio signal (578-1). For example, the second frequency range may be defined as a frequency range in which the third audio signal (580-1) is output with the greatest sound pressure among the frequency ranges in which it is output. For example, a frequency range having a high audible sensitivity may be defined as a frequency range of audio that is effectively audible to the human ear (e.g., a frequency range from 3 kilohertz (kHz) to 4 kHz). For example, when the speaker (330) is burned in (or aged, or broken in) according to the output of the first audio signal (570-1) and the second audio signal (578-1), the burned-in speaker may have a second resonant frequency (e.g., the second resonant frequency (635) of FIG. 6). For example, when the burned-in speaker has the second resonant frequency, the burned-in speaker may output an audio signal with a relatively large sound pressure in a second frequency range having a relatively high audible sensitivity. For example, at least one processor (310) may effectively notify the user of an emergency state by outputting a third audio signal (580-1) through the burned-in speaker.

[0088] For example, at least one processor (310) can effectively notify the user of an emergency condition by outputting the third audio signal (580-1) with a relatively large sound pressure in a second frequency range having a relatively high audible sensitivity, even if the third audio signal (580-1) is output for a relatively short third time period (582). For example, at least one processor (310) can output the third audio signal (580-1) for a relatively short third time period (582), so that relatively low heat generation of the speaker (330) can occur. For example, since the speaker (330) generates relatively low heat generation, damage to the speaker (330) can be reduced, or discomfort to the user can be relieved. For example, since the speaker (330) generates relatively low heat generation, the battery of the wearable device (300) can be discharged relatively slowly.

[0089] For example, in order to reduce heat generation of the speaker (330), at least one processor (310) may stop (or refrain from, or not output) outputting the audio signal after outputting the third audio signal (580-1), or may output the fourth audio signal at a fifth sound pressure lower than the third sound pressure (576). For example, at least one processor (310) may stop (or refrain from, or not output) outputting the audio signal during a fourth time period (583) that is relatively shorter than the time period (230) of FIG. 2, or may output the fourth audio signal at a fifth sound pressure lower than the third sound pressure (576), depending on relatively low heat generation. For example, at least one processor (310) can effectively notify the user of an emergency state by stopping (or refraining from, or not outputting) an audio signal during a fourth time interval (583) that is relatively shorter than the time interval (230) of FIG. 2, or by outputting a fourth audio signal at a fifth sound pressure that is lower than the third sound pressure (576).

[0090] For example, at least one processor (310) may output a fifth audio signal (570-2) through the speaker (330) after outputting a third audio signal (580-1) and then, as a reference time elapses, output the fifth audio signal (570-2). For example, the fifth audio signal (570-2) may correspond to the first audio signal (570-1). For example, at least one processor (310) may output a sixth audio signal (578-2) through the speaker (330) after outputting the fifth audio signal (570-1). For example, the sixth audio signal (578-2) may correspond to the second audio signal (578-1).

[0091] For example, at least one processor (310) may output a seventh audio signal (580-2) through the burnt-in (or aged, or broken-in) speaker by outputting a sixth audio signal (578-2) and then outputting a seventh audio signal (580-2). For example, the seventh audio signal (580-2) may correspond to the third audio signal (580-1).

[0092] For example, at least one processor (310) can repeatedly output a first audio signal (570-1), a second audio signal (578-1), and a third audio signal (580-1) through the speaker (330) according to a specified cycle. For example, the first audio signal (570-1), the second audio signal (578-1), and the third audio signal (580-1) can constitute one section or one segment.

[0093] For example, at least one processor (310) can repeatedly output the first audio signal (570-1), the second audio signal (578-1), the third audio signal (580-1), and the fourth audio signal through the speaker (330) according to a specified period. For example, the specified period may include one period during the fifth time interval (584). For example, at least one processor (310) can effectively notify the user of an emergency state by repeatedly outputting the first audio signal (570-1), the second audio signal (578-1), the third audio signal (580-1), and the fourth audio signal through the speaker (330) according to a specified period. For example, at least one processor (310) can effectively provide audio corresponding to an emergency siren by repeatedly outputting the first audio signal (570-1), the second audio signal (578-1), the third audio signal (580-1), and the fourth audio signal through the speaker (330) according to a specified cycle.

[0094] For example, at least one processor (310) may detect that the user's emergency state has ended while providing the audio corresponding to the emergency siren. For example, at least one processor (310) may stop (or refrain from, or not output) the output of the first audio signal (570-1), the second audio signal (578-1), the third audio signal (580-1), and / or the fourth audio signal based on the termination of the emergency state.

[0095] FIG. 7A is a perspective view illustrating an example of a speaker positioned within a wearable device according to various embodiments.

[0096] Referring to FIG. 7A, the wearable device (300) may further include a display (715), a housing, and a wrist-wearable structure (700) detachably coupled to the housing.

[0097] For example, the wrist-worn structure (700) may include a first part (700-1). For example, the wrist-worn structure (700) may include a first part (700-1) of a detachable wrist-worn structure (700) and a second part (700-2) of a detachable wrist-worn structure (700).

[0098] For example, the housing may include a front side (705) disposed below the display (715). For example, the housing may include a side side (720). For example, the side side (720) of the housing may include a first portion detachably coupled with a first part (700-1) of the wrist-worn structure (700). For example, the side side (720) of the housing may include a second portion opposite the first portion of the housing and detachably coupled with the second part (700-2) of the wrist-worn structure (700). For example, the side side (720) of the housing may include a third portion between the first portion of the housing and the second portion of the housing. For example, the side side (720) of the housing may include a fourth portion opposite the third portion and between the first portion of the housing and the second portion of the housing. For example, the housing may include a rear side (710) that comes into contact with the wrist of a user wearing the wearable device (300).

[0099] For example, the third portion of the housing may include a first speaker hole (730) having a first size and a second speaker hole (725) spaced apart from the first speaker hole (730) and having a second size smaller than the first size. For example, the first speaker hole (730) and the second speaker hole (725) may be arranged side by side within the third portion of the housing.

[0100] For example, the housing may be aligned with an acoustic duct (or acoustic path) between the speaker (330) and the second speaker hole (725), and an audio signal from the speaker (330) may be output through the acoustic duct and the second speaker hole (725).

[0101] For example, the wearable device (300) may include an amplifier circuit (or codec). For example, the amplifier circuit may be included in a power management integrated circuit (PMIC) within the wearable device (300). For example, the speaker (330) may be configured to amplify an audio signal generated by a digital to analog converter (DAC) circuit within the PMIC of the wearable device (300).

[0102] FIG. 7b is a perspective view illustrating an exemplary speaker structure including a first speaker and a second speaker according to various embodiments.

[0103] FIG. 7c is an exploded perspective view illustrating an exemplary speaker structure including a first speaker and a second speaker according to various embodiments.

[0104] Referring to FIGS. 7b and 7c, the speaker structure (788) may include a diaphragm assembly (790), a first coil (791), a second coil (792), a frame (793), a connecting structure (794), a first magnet (796), a second magnet (797), and a yoke (798).

[0105] The first magnet (796) and the second magnet (797) may be placed on (or attached to) the yoke (798). For example, the yoke (798) may secure the magnets and collect the force of the magnetic fields generated by the first magnet (796) and the second magnet (797) to increase the output and / or efficiency of the speaker.

[0106] For example, the first magnet (796) can be at least partially surrounded by the first coil (791). For example, the first coil (791) can laterally surround the first magnet (796). For example, the first coil (791) can surround the first magnet (796) when viewed from above. As a non-limiting example, the first coil (791) can be spaced apart from the first magnet (796). As a non-limiting example, the first coil (791) can be in substantial contact with the first magnet (796). For example, the second magnet (797) can be at least partially surrounded by the second coil (792). For example, the second coil (792) can laterally surround the second magnet (797). For example, the second coil (792) may surround the second magnet (797) when viewed from above. As a non-limiting example, the second coil (792) may be spaced apart from the second magnet (797). As a non-limiting example, the second coil (792) may be in substantial contact with the second magnet (797). For example, the first coil (791) may vibrate by a magnetic field formed by the speaker structure (788) by interacting with the first magnet (796). For example, the second coil (792) may vibrate by a magnetic field formed by the speaker structure (788) by interacting with the second magnet (797).

[0107] The frame (793) can be used to mount the diaphragm assembly (790), the first coil (791), the second coil (792), the first magnet (796), the second magnet (797), and the yoke (798). The frame (793) can be described as a speaker housing. The shape and size of the first portion of the frame (793) can correspond to the shape and size of the diaphragm assembly (790). The shape and size of the second portion of the frame (793) can correspond to the shape and size of the first coil (791). The shape and size of the third portion of the frame (793) can correspond to the shape and size of the second coil (792). The shape and size of the fourth portion of the frame (793) can correspond to the shape and size of the first magnet (796). The shape and size of the fifth part of the frame (793) may correspond to the shape and size of the second magnet (797). The shape and size of the sixth part of the frame (793) may correspond to the shape and size of the yoke (798). The frame (793) forms at least a portion of the exterior of the speaker structure (788) and may support the diaphragm assembly (790).

[0108] A connecting structure (794) may be used to couple or connect a speaker structure (788) to a housing of a wearable device (300). The connecting structure (794) may be positioned or located between a frame (793) and a yoke (798).

[0109] The diaphragm assembly (790) may be disposed on the top portion (or front portion) of the frame (793). The diaphragm assembly (790) may include a diaphragm (790-1) arranged in relation to a first coil (791) surrounding a first magnet (796). The diaphragm (790-1) may be disposed on (or above) the first coil (791) surrounding the first magnet (796). The diaphragm assembly (790) may include a diaphragm (790-2) arranged in relation to a second coil (792) surrounding a second magnet (797). The diaphragm (790-2) may be disposed on (or above) the second coil (792) surrounding the second magnet (797). For example, the diaphragm (790-1) and / or the diaphragm (790-2) may be configured to vibrate based on the vibration of the first coil (791) and the second coil (792). For example, audio may be output from the speaker by vibrating the diaphragm (790-1) and / or the diaphragm (790-2). As a non-limiting example, the vibration of the diaphragm (790-1) may be independent of the vibration of the diaphragm (790-2).

[0110] For example, at least one processor (310) may output audio corresponding to an emergency siren through a speaker (330) based on the vibration of the diaphragm (790-2).

[0111] FIG. 8 is a diagram including a graph showing examples of a resonant frequency of a speaker according to the length of an acoustic path of the speaker according to various embodiments.

[0112] Referring to FIG. 8, the chart (800) represents the change in the maximum sound pressure of an audio signal that can be output through a speaker (330) according to frequency. The horizontal axis (805) in the chart (800) represents the frequency of the audio signal, and the vertical axis (810) in the chart (800) represents the maximum sound pressure of an audio signal that can be output through the speaker (330).

[0113] For example, the speaker (330) may include a first speaker (850-1) and / or a second speaker (850-2). For example, the first speaker (850-1) may include a first acoustic path (or acoustic duct, or acoustic conduit) (855-1) of a first length (860-1).

[0114] For example, the maximum sound pressure of an audio signal that can be output through the first speaker (850-1) can be expressed as a line (830). For example, the maximum sound pressure of an audio signal that can be output through the first speaker (850-1) can be represented as a first sound pressure (840) at a first frequency (835). For example, the first sound pressure (840) can be a maximum value of the maximum sound pressure of an audio signal that can be output through the first speaker (850-1). For example, the first speaker (850-1) can have the first frequency (835) as a resonant frequency by having the first sound pressure (840) as the maximum sound pressure of an audio signal that can be output at the first frequency (835). For example, the first speaker (850-1) can output an audio signal with a relatively large sound pressure at the first frequency (835) by having the first frequency (835) as a resonant frequency.

[0115] For example, the second speaker (850-2) may include a second acoustic path (or acoustic duct, or acoustic conduit) (855-2) of a second length (860-2). For example, the second length (860-2) may be longer than the first length (860-1).

[0116] For example, the maximum sound pressure of an audio signal that can be output through the second speaker (850-2) can be expressed as a line (815). For example, the maximum sound pressure of an audio signal that can be output through the second speaker (850-2) can be expressed as a second sound pressure (825) at a second frequency (820). For example, the second sound pressure (825) can be a maximum value of the maximum sound pressure of an audio signal that can be output through the second speaker (850-2). For example, the second speaker (850-2) can have the second frequency (820) as a resonant frequency by having the second sound pressure (825) as the maximum sound pressure of an audio signal that can be output at the second frequency (820). For example, the second speaker (850-2) can output an audio signal with a relatively large sound pressure at the second frequency (820) by having the second frequency (820) as a resonant frequency.

[0117] For example, the first frequency (835) may be lower than the second frequency (820) by a difference (845) between the first frequency (835) and the second frequency (820). For example, the resonant frequency of the speaker (330) may be lowered as the speaker (330) has a relatively short acoustic path (or acoustic duct, or acoustic conduit) of the speaker (330). For example, a first speaker (850-1) having an acoustic path (855-1) of a relatively short first length (860-1) may output audio data with a relatively greater sound pressure than a second speaker (850-2) having an acoustic path (855-2) of a relatively long second length (860-2) in a first frequency (835) band lower than the second frequency (820). For example, at least one processor (310) can output audio data at a relatively low frequency band and with a relatively high sound pressure through a first speaker (850-1) having a relatively short first length (860-1) of sound path (855-1). For example, at least one processor (310) can effectively notify a user of an emergency state by outputting an audio signal through the first speaker (850-1) having a relatively short first length (860-1) of sound path (855-1).

[0118] FIGS. 9A and 9B are front and rear perspective views, respectively, illustrating exemplary electronic devices according to various embodiments.

[0119] Referring to FIGS. 9A and 9B , an electronic device (900) according to one embodiment (e.g., the wearable device (300) of FIG. 3 ) may include a housing (910) including a first side (or front side) (910A), a second side (or back side) (910B), and a side surface (910C) surrounding a space between the first side (910A) and the second side (910B), and a fastening member (950, 960) connected to at least a portion of the housing (910) and configured to releasably fasten the electronic device (900) to a body part (e.g., a wrist or ankle) of a user. In one embodiment (not shown), the housing may also refer to a structure forming a portion of the first side (910A), the second side (910B), and the side surface (910C) of FIGS. 9A and 9B . In one embodiment, the first side (910A) may be formed by a front plate (901) that is at least partially substantially transparent (e.g., a glass plate or a polymer plate comprising various coating layers). The second side (910B) may be formed by a substantially opaque back plate (907). The back plate (907) may be formed of, for example, coated or colored glass, ceramic, polymer, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the foregoing materials. The side surface (910C) may be formed by a side bezel structure (or “side member”) (906) that is coupled to the front plate (901) and the back plate (907) and comprises a metal and / or a polymer. In various embodiments, the back plate (907) and the side bezel structure (906) may be formed integrally and comprise the same material (e.g., a metal material such as aluminum). The above-mentioned fastening member (950, 960) may be formed of various materials and shapes. The integral and multiple unit links may be formed to be mutually movable by a combination of at least two of the above-mentioned materials, such as woven fabric, leather, rubber, urethane, metal, ceramic, or a combination of the above-mentioned materials.

[0120] According to one embodiment, the electronic device (900) may include at least one of a display (920, see FIG. 10), an audio module (905, 908), a sensor module (911), a key input device (902, 903, 904), and a connector hole (909).

[0165] Figure 12 is a block diagram of an audio module according to various embodiments.

[0166] Fig. 12 is a block diagram (1200) of an audio module (1170) according to various embodiments. Referring to Fig. 12, the audio module (1170) may include, for example, an audio input interface (1210), an audio input mixer (1220), an analog to digital converter (ADC) (1230), an audio signal processor (1240), a digital to analog converter (DAC) (1250), an audio output mixer (1260), or an audio output interface (1270).

[0167] The audio input interface (1210) can receive an audio signal corresponding to a sound acquired from the outside of the electronic device (1101) as part of the input device (1150) or through a microphone (e.g., a dynamic microphone, a condenser microphone, or a piezo microphone) configured separately from the electronic device (1101). For example, when acquiring an audio signal from an external electronic device (1102) (e.g., a headset or a microphone), the audio input interface (1210) can be connected to the external electronic device (1102) by wire through a connection terminal (1178) or wirelessly (e.g., Bluetooth communication) through a wireless communication module (1192) to receive the audio signal. According to one embodiment, the audio input interface (1210) can receive a control signal (e.g., a volume control signal using an input button) related to the audio signal acquired from the external electronic device (1102). The audio input interface (1210) includes a plurality of audio input channels and can receive different audio signals for each audio input channel. In one embodiment, additionally or alternatively, the audio input interface (1210) can receive audio signals from other components of the electronic device (1101), such as the processor (1120) or the memory (1120).

[0168] The audio input mixer (1220) can synthesize a plurality of input audio signals into at least one audio signal. According to one embodiment, the audio input mixer (1220) can synthesize a plurality of analog audio signals input through the audio input interface (1210) into at least one analog audio signal.

[0169] The ADC (1230) can convert an analog audio signal into a digital audio signal. According to one embodiment, the ADC (1230) can convert an analog audio signal received through an audio input interface (1210) or, additionally or alternatively, an analog audio signal synthesized through an audio input mixer (1220) into a digital audio signal.

[0170] The audio signal processor (1240) may perform various processing on a digital audio signal input through the ADC (1230) or a digital audio signal received from another component of the electronic device (1101). For example, the audio signal processor (1240) may change a sampling rate, apply one or more filters, interpolate, amplify or attenuate (e.g., amplify or attenuate a portion of a frequency band or the entire frequency band), noise process (e.g., noise or echo reduction), change a channel (e.g., switch between mono and stereo), mix, or extract a specified signal on one or more digital audio signals. According to one embodiment, at least some functions of the audio signal processor (1240) may be implemented in the form of an equalizer.

[0171] The DAC (1250) can convert a digital audio signal into an analog audio signal. According to one embodiment, the DAC (1250) can convert a digital audio signal processed by an audio signal processor (1240) or a digital audio signal obtained from another component of the electronic device (1101) into an analog audio signal.

[0172] The audio output mixer (1260) can synthesize a plurality of audio signals to be output into at least one audio signal. According to one embodiment, the audio output mixer (1260) can synthesize an audio signal converted into analog through the DAC (1250) and another analog audio signal (e.g., an analog audio signal received through the audio input interface (1210)) into at least one analog audio signal.

[0173] The audio output interface (1270) can output an analog audio signal converted by the DAC (1250), or additionally or alternatively, an analog audio signal synthesized by the audio output mixer (1260) to the outside of the electronic device (1101) through an audio output device (1155) (e.g., a speaker (e.g., a dynamic driver or a balanced armature driver), or a receiver). According to one embodiment, the audio output device (1155) includes a plurality of speakers, and the audio output interface (1270) can output an audio signal having a plurality of different channels (e.g., stereo, or 5.1 channels) through at least some of the speakers. According to one embodiment, the audio output interface (1270) can be connected to an external electronic device (1102) (e.g., an external speaker or a headset) by wire through a connection terminal (1178), or wirelessly through a wireless communication module (1192) to output an audio signal.

[0174] According to one embodiment, the audio module (1170) may generate at least one digital audio signal by synthesizing a plurality of digital audio signals as at least a part of the function of the audio signal processor (1240) without separately having an audio input mixer (1220) or an audio output mixer (1260).

[0175] According to one embodiment, the audio module (1170) may include an audio amplifier (not shown) (e.g., a speaker amplifier circuit) capable of amplifying an analog audio signal input through the audio input interface (1210) or an audio signal to be output through the audio output interface (1270). According to one embodiment, the audio amplifier may be configured as a separate module from the audio module (1170).

[0176] According to various embodiments as described above, the wearable device (e.g., the wearable device (300) of FIG. 3) may include a memory (e.g., the memory (320) of FIG. 3) that stores instructions and includes one or more storage media, a speaker (e.g., the speaker (330) of FIG. 3), and at least one processor (e.g., the at least one processor (310) of FIG. 3) that includes a processing circuit. The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to detect an emergency condition (e.g., the condition (105) of FIG. 1) of a user (e.g., the user (110) of FIG. 1). The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to output, through the speaker having a first resonant frequency, a first audio signal (e.g., the first audio signal (515-1) of FIG. 5A) in a first frequency range at a first sound pressure (e.g., the first sound pressure (520) of FIG. 5A) to provide audio corresponding to an emergency siren based on the emergency condition. The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to output, through the speaker having a second resonant frequency, a second audio signal (e.g., the second audio signal (530-1) of FIG. 5A) in a second frequency range having a higher audible sensitivity than the audible sensitivity of the first frequency range at a second sound pressure greater than the first sound pressure (e.g., the second sound pressure (535) of FIG. 5A), after outputting the first audio signal. The resonant frequency of the speaker may be changed from the first resonant frequency to the second resonant frequency lower than the first resonant frequency in response to outputting the first audio signal.

[0177] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to output a third audio signal at a third sound pressure level less than the first sound pressure level after outputting the second audio signal.

[0178] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to output the first audio signal through the speaker to burn-in the speaker. The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to output the second audio signal through the burned-in speaker after outputting the first audio signal. The resonant frequency of the speaker may be changed from the first resonant frequency to the second resonant frequency as the speaker is burned-in.

[0179] For example, the second negative pressure may include a full-scale negative pressure.

[0180] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to repeatedly output the first audio signal and the second audio signal at a specified period to provide the audio corresponding to an emergency siren based on the emergency condition.

[0181] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to repeatedly output the first audio signal, the second audio signal, and the third audio signal according to a specified cycle to provide the audio corresponding to an emergency siren based on the emergency condition.

[0182] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to detect that the user's emergency condition has ended while providing the audio corresponding to the emergency siren. The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to stop outputting the first audio signal and the second audio signal based on the ending of the emergency condition.

The third portion of the housing may include a first speaker hole having a first size and a second speaker hole spaced apart from the first speaker hole and having a second size smaller than the first size. The housing may be aligned with an acoustic duct between the speaker and the second speaker hole. The wearable device may be configured to output an audio signal from the speaker through the acoustic duct and the second speaker hole.

[0184] For example, the speaker may be configured to amplify an audio signal generated by a digital to analog converter (DAC) circuit within a power management integrated circuitry (PMIC) of the wearable device.

[0185] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to output a third audio signal in the first frequency range through the speaker having the first resonant frequency at a fourth sound pressure that increases within a range from a third sound pressure that is less than the first sound pressure to the first sound pressure, to provide audio corresponding to an emergency siren based on the emergency condition. The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to output the first audio signal after outputting the third audio signal.

The method may include an operation of outputting the second audio signal through the burned-in speaker after outputting the first audio signal.
