[0001] The present disclosure relates to an electronic device including a speaker.

[0002] An electronic device may include a speaker and an acoustic duct formed around the speaker. Sound output from the speaker may be transmitted to the outside of the electronic device through the duct.

[0003] The electronic device may be configured to perform a function to remove water if water enters the acoustic duct. For example, the electronic device may output a sound from the speaker to remove water that has entered the acoustic duct.

[0004] The above information may be provided as background information to aid in understanding the present disclosure. None of the above is claimed to be prior art related to the present disclosure, nor can it be used to determine prior art.

[0005] If the acoustic duct is structured in a way that makes it difficult to remove water, even if the speaker outputs a sound to remove water, water that has entered the duct may be difficult to remove. Furthermore, if multiple speakers share a single acoustic duct, even if the speaker outputs a sound to remove water, water that has entered the duct may be difficult to remove.

[0006] Therefore, in cases where the sound duct is formed in a structure that makes it difficult to remove water, and in cases where multiple speakers share a single sound duct, a configuration capable of removing water that has entered the sound duct may be required.

[0007] The technical problems to be achieved in the present disclosure are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by a person having ordinary knowledge in the technical field to which the present disclosure pertains.

The plurality of speakers may be configured to output sound to the outside of the electronic device through at least one conduit.

[0009] In one embodiment, the plurality of speakers may be configured to simultaneously output a first sound corresponding to a first frequency range and a second sound corresponding to a second frequency range different from the first frequency range based on the occurrence of an event to remove a foreign object inserted in the duct or near the speaker.

[0010] In one embodiment, the first frequency range may be associated with a resonant frequency of a first speaker among the plurality of speakers, and the second frequency range may be associated with a resonant frequency of a second speaker among the plurality of speakers.

[0011] An electronic device according to one embodiment of the present disclosure may include a first speaker, a conduit, a processor, and memory. The conduit may be formed around the first speaker. The memory may be operatively connected to the processor.

[0012] In one embodiment, the memory may store instructions that, when executed by the processor, cause the electronic device to output a first sound including a plurality of sub-sounds having different frequencies within a first frequency range through a first speaker at a predetermined sound pressure, and each sub-sound included in the first sound temporarily increases in sound pressure according to a predetermined order.

[0013] An electronic device according to one embodiment of the present disclosure can effectively remove foreign substances introduced into a pipe by using sound output from a speaker.

[0014] An electronic device according to one embodiment of the present disclosure can effectively remove foreign substances introduced into a conduit even when multiple speakers share the same conduit.

[0015] An electronic device according to one embodiment of the present disclosure can improve the acoustic performance of a speaker by removing foreign substances introduced into a conduit.

[0016] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned will be clearly understood by a person having ordinary skill in the art to which the present disclosure pertains.

The processor (231) may execute a program (or one or more instructions) stored in the memory (241) to perform a designated operation. For example, the processor (231) may receive a user's voice input (e.g., a user's speech) through the I / O interface (221). In one example, the processor (231) may perform voice activity detection (VAD) using at least one sensor (not shown) of the second electronic device (202). The processor (231) may detect a user's speech of the second electronic device (202) using an acceleration sensor and / or a microphone.

[0074] An intelligent server (300) of one embodiment can receive a user's voice input from a first electronic device (201) via a first network (299). The intelligent server (300) can convert audio data corresponding to the received voice input into text data. The intelligent server (300) can generate at least one plan for performing a task corresponding to the user's voice input based on the text data.

[0077] The natural language platform (320) may include an automatic speech recognition (ASR) module (321), a natural language understanding (NLU) module (323), a planner module (325), a natural language generator (NLG) module (327), and / or a text-to-speech (TTS) module (329).

[0078] The automatic speech recognition module (321) can convert the voice input received from the first electronic device (201) into text data. The natural language understanding module (323) can identify the user's intent and / or parameters (e.g., entities and / or slots) based on the text data of the voice input. The user's intent corresponds to the voice input and may include information indicating an action (or function) that the user wishes to perform using the device. The slot may be detailed information related to the user's intent. The slot may be acquired based on a domain corresponding to the utterance. The slot may be variable information required to perform the action. In one embodiment, the variable information constituting the slot may include a named entity.

[0079] The planner module (325) can generate a plan using the intent and / or parameters determined by the natural language understanding module (323). For example, the planner module (325) can determine at least one domain necessary to perform a task based on the determined intent. The domain may correspond to a category (or service) associated with an action (or function) that the user wishes to perform using the device. The domain may be classified according to a service (e.g., an app) related to the text. The domain may be related to the user's intent corresponding to the text. The domain may be classified according to, for example, the type of application that received the voice input and / or the type of service to be provided based on the voice input, but is not limited thereto. In one example, the determination of the domain may be performed by another module (e.g., the natural language understanding module (323)). The planner module (325) may determine a plurality of actions included in each of the at least one domain determined based on the intent. The planner module (325) can determine parameters required to execute a plurality of determined actions or result values ​​output by the execution of the plurality of actions. The parameters and result values ​​can be defined as concepts of a specified format (or class). For example, the plan can include a plurality of actions and / or a plurality of concepts determined by the user's intention. The planner module (325) can determine the relationship between the plurality of actions and / or the plurality of concepts in a step-by-step (or hierarchical) manner. For example, the planner module (325) can identify the execution order of the plurality of actions (e.g., the plurality of actions determined based on the user's intention) based on the plurality of concepts (e.g., parameters required to execute the plurality of actions and results output by the execution of the plurality of actions). The planner module (325) can generate a plan including association information (e.g., ontology) between the plurality of actions and the plurality of concepts.The planner module (325) can create a plan using information (e.g., at least one capsule) stored in a capsule database (330) in which a set of relationships between concepts and actions is stored.

[0080] The planner module (325) can generate a plan based on an artificial intelligence (AI) system. For example, the AI ​​system can include one or more electronic devices and / or one or more processing circuits to execute a rule-based system, a neural network-based system (e.g., a feedforward neural network (FNN) and / or a recurrent neural network (RNN)), or a combination thereof. The AI ​​system described above is exemplary, and the AI ​​system can be an AI system based on any machine learning-based model. The planner module (325) can select a plan corresponding to a user request from a set of predefined plans, or generate a plan in real time in response to a user request.

[0081] The natural language generation module (327) can convert specified information into text format. The information converted into text format may be in the form of natural language speech. The text-to-speech conversion module (329) can convert information in text format into information in speech format.

[0082] The capsule database (330) can store information on the relationship between multiple concepts and actions corresponding to multiple domains (e.g., applications). The capsule database (330) can store at least one capsule (e.g., capsule (331) and / or capsule (333)) in the form of a concept action network (CAN). For example, the capsule database (330) can store an action for processing a task corresponding to a user's voice input and / or parameters required for the action in the form of a CAN. A capsule can include multiple action objects (or action information) and / or concept objects (or concept information) included in a plan. For example, capsules (331, 333) can be created for each domain and stored in the capsule database (330), but are not limited thereto.

[0083] The execution engine (340) can produce results using the generated plan. The end user interface (350) can transmit the produced results to the first electronic device (201).

[0084] According to one embodiment, some functions (e.g., natural language platform (320)) or all functions of the intelligent server (300) may be implemented in the first electronic device (201). For example, the first electronic device (201) may execute one or more programs including a natural language platform (e.g., natural language platform (250) of FIG. 3) separately from the intelligent server (300). For example, the electronic device (201) may directly perform at least some of the operations of the natural language platform (320) of the intelligent server (300) (e.g., automatic speech recognition module (321), natural language understanding module (323), planner module (325), natural language generation module (327), and / or text-to-speech module (329)).

[0085] In one embodiment, a service server (399) may provide a service (e.g., food ordering or hotel reservation) designated to a first electronic device (201). The service server (399) may be a server operated by a different operator than the intelligent server (300). The service server (399) may communicate with the intelligent server (300) and / or the first electronic device (201) via the first network (299). The service server (399) may communicate with the intelligent server (300) via a separate connection (not shown). The service server (399) may provide the intelligent server (300) with information for generating a plan corresponding to a voice input received by the first electronic device (201) (e.g., operation information and / or concept information for providing a designated service). The provided information may be stored in a capsule database (330). The service server (399) can provide the result information according to the plan received from the first electronic device (201) to the intelligent server (300).

[0086] FIG. 3 is a block diagram illustrating an integrated intelligence system according to one embodiment.

[0087] Referring to FIG. 3, the integrated intelligence system may include a first electronic device (201), a second electronic device (202), and an intelligent server (302). The first electronic device (201) and the intelligent server (302) may be connected to each other via a network and may transmit and receive data. The first electronic device (201) and the second electronic device (202) may be connected to each other via a short-range network and may transmit and receive data. According to one embodiment, the integrated intelligence system may be composed of a single device or multiple devices. For example, each device may include identical or similar functional configurations, and the configuration of one device may be replaced with the configuration of another device.

[0088] According to one embodiment, the intelligent server (302) may include the entire configuration or at least a portion of the configuration of the intelligent server (300) illustrated in FIG. 2. For example, the intelligent server (302) may execute one or more programs including the natural language platform (320) of the intelligent server (300) of FIG. 2 and / or store the capsule database (330) of FIG. 2. The configuration of the intelligent server (302) is not limited to that illustrated in FIG. 3. For example, at least a portion of the configuration of the natural language platform (320) (e.g., the automatic speech recognition module (321), the natural language understanding module (323), the planner module (325), the natural language generation module (327), and / or the text-to-speech module (329)) may be omitted from the intelligent server (302). For example, the intelligent server (302) may further include some components of the intelligent server (300) of FIG. 2 (e.g., the front end (310), the execution engine (340), and / or the end user interface (350)).

[0089] The first electronic device (201) may execute one or more programs including a natural language platform (250) and / or store a capsule database (260). For example, the first electronic device (201) may further execute one or more programs including a natural language platform (250) and / or store a capsule database (260) while including components of the first electronic device (201) of FIG. 2.

[0090] The natural language platform (250) may include an automatic speech recognition module (251), a natural language understanding module (253), a planner module (255), a natural language generation module (257), and / or a text-to-speech module (259). The automatic speech recognition module (251), the natural language understanding module (253), the planner module (255), the natural language generation module (257), and the text-to-speech module (259) may perform functions identical to or similar to those of the automatic speech recognition module (321), the natural language understanding module (323), the planner module (325), the natural language generation module (327), and the text-to-speech module (329) of FIG. 2, respectively.

[0091] The capsule database (260) may perform the same or similar functions as the capsule database (330) of the intelligent server (300, 302). The capsule database (260) may store information about the relationships between multiple operations and multiple concepts included in the plan generated by the planner module (255). For example, the capsule database (260) may store at least one capsule (e.g., capsule (261) and / or capsule (263)).

[0092] According to one embodiment, the first electronic device (201) (e.g., the natural language platform (250) and / or capsule database (260)) and the intelligent server (302) (e.g., the natural language platform (320) and / or capsule database (330)) may perform at least one function (or operation) in conjunction with each other, or may independently perform at least one function (or operation). For example, the first electronic device (201) may perform voice recognition on its own without transmitting the received user's voice input to the intelligent server (302). As an example, the first electronic device (201) may convert the received voice input into text data through the automatic voice recognition module (251). The first electronic device (201) may transmit the converted text data to the intelligent server (302). The intelligent server (302) may determine (or identify) the user's intention and / or parameters from the text data through the natural language understanding module (323). The intelligent server (302) can generate a plan through the planner module (325) based on the determined intent and parameters and transmit the plan to the first electronic device (201), or can transmit the determined intent and parameters to the first electronic device (201) and cause the plan to be generated through the planner module (255) of the first electronic device (201). The planner module (255) of the first electronic device (201) can generate at least one plan for performing a task corresponding to a voice input using information stored in the capsule database (260).

[0093] For example, the first electronic device (201) can convert voice input received through the automatic speech recognition module (251) into text data, and determine (or identify) the user's intention and / or parameters based on the text data through the natural language understanding module (253). The first electronic device (201) can generate a plan through the planner module (255) based on the determined intention and parameters, or transmit the determined intention and parameters to the intelligent server (302) so that the planner module (325) of the intelligent server (302) can generate a plan. For example, when the planner module (255) and / or the capsule database (260) are not included in the first electronic device (201), the first electronic device (201) can generate a plan through the intelligent server (302).

[0094] For example, the first electronic device (201) can detect a speech pattern that is difficult to learn in an automatic speech recognition module (251) or a natural language understanding module (253), and transmit a voice input corresponding to the detected speech pattern to an intelligent server (302) so that the automatic speech recognition module (321) or the natural language understanding module (323) of the intelligent server (302) can process it.

[0095] Embodiments of the present disclosure are not limited to the examples described above. For example, the first electronic device (201) may process the received voice input only within the terminal and produce a result corresponding to the voice input. For example, the first electronic device (201) and the intelligent server (302) may not only divide the voice input into modules and process it, but may also collaborate with each other to process it. For example, the natural language understanding module (253) of the first electronic device (201) and the natural language understanding module (323) of the intelligent server (302) may work together to produce a single result value (e.g., the user's intention and / or parameters).

[0096] The second electronic device (202) can execute one or more programs including an automatic speech recognition (ASR) module (252) and / or a text-to-speech (TTS) module (254). For example, the second electronic device (202) can include components of the second electronic device (202) of FIG. 2 and execute one or more programs including an automatic speech recognition module (252) and / or a text-to-speech module (254). The automatic speech recognition module (252) and the text-to-speech module (254) can perform functions identical to or similar to the automatic speech recognition module (321) and the text-to-speech module (329) of FIG. 2, respectively.

[0097] According to one embodiment, the first electronic device (201) and the second electronic device (202) may perform at least one function (or operation) in conjunction with each other, or may independently perform at least one function (or operation). For example, the second electronic device (202) may perform voice recognition for a voice input using an automatic voice recognition module (252). The second electronic device (202) may perform a function corresponding to the voice input based on the voice recognition. For example, the second electronic device (202) may transmit a command corresponding to the recognized voice command to the first electronic device (201). The second electronic device (202) may output data received from the first electronic device (201). For example, the second electronic device (202) may convert data received from the first electronic device (201) into voice using a text-to-speech conversion module (254) and output the converted voice.

[0146] According to one embodiment, an electronic device (400) may be formed such that one side (418A) of a partition wall (418) is inclined relative to one side (420A) of a speaker unit (420). One side (418A) of the partition wall (418) may be inclined in a direction away from the speaker unit (420). For example, referring to FIG. 7C, one side (420A) of the speaker unit (420) may be formed substantially parallel to the Z-axis direction, and one side (418A) of the partition wall (418) may be formed substantially parallel to a direction inclined by a predetermined angle relative to the Z-axis direction. Referring to FIG. 7C, one side (418A) of the partition wall (418) may be formed such that the distance from one side (420A) of the speaker unit (420) increases as the distance increases in the positive Z-axis direction.

[0147] According to one embodiment, an electronic device (400) may be formed such that one side (419A) of a side region (419) is inclined relative to one side (420A) of a speaker unit (420). For example, referring to FIG. 7C, one side (420A) of the speaker unit (420) may be formed substantially parallel to the Z-axis direction, and one side (419A) of the side region (419) may be formed substantially parallel to a direction inclined by a predetermined angle relative to the Z-axis direction. Referring to FIG. 7C, one side (419A) of the side region (419) may be formed such that the distance from one side (420A) of the speaker unit (420) increases as it goes in the negative Z-axis direction.

[0148] In an electronic device (400) according to one embodiment, when one side (418A) of the partition wall (418) and / or one side (419A) of the side region (419) is formed in an inclined shape with respect to one side (420A) of the speaker unit (420), foreign substances (e.g., water) that have entered between the speaker unit (420) and the partition wall (418) or between the speaker unit (420) and the side region (419) can be easily discharged to the outside of the electronic device (400). For example, when one side (418A) of the partition wall (418) is formed in an inclined shape, water moved by sound (e.g., the first sound (1000) of FIG. 10) can be more easily moved to the outside of the electronic device (400). Additionally, if one side (418A) of the bulkhead (418) is formed in an inclined shape, water flowing into the electronic device (400) can more easily be evaporated by heat.

[0149] In one embodiment, at least one conduit (415) may be formed in the housing (410). For example, referring to FIG. 7d, the conduit (415) may include a first conduit (4151) and / or a second conduit (4152).

[0150] In one embodiment, the first conduit (4151) and the second conduit (4152) may each correspond to at least a portion of the speaker unit (420). For example, the first conduit (4151) may be a conduit corresponding to the first speaker (421, see FIG. 6B). The second conduit (4152) may be a conduit corresponding to the second speaker (422, see FIG. 6B).

[0151] Referring to FIGS. 7a, 7b, and 7c, two different sounds (S1, S2) can be output simultaneously from the speaker unit (420). For example, a first sound (S1) and / or a second sound (S2) can be output simultaneously from a first speaker (421, see FIG. 6b) of the speaker unit (420).

[0152] In one embodiment, the first sound (S1) and the second sound (S2) may correspond to different frequency ranges. For example, the first sound (S1) may correspond to a first frequency range (fr1, see FIG. 10). The second sound (S2) may correspond to a second frequency range (fr2, see FIG. 11). For example, the first frequency range (fr1, see FIG. 10) and the second frequency range (fr2, see FIG. 11) may be different from each other.

[0153] In one embodiment, the electronic device (400) can remove foreign substances inserted into the conduit (415) or near the speaker unit (420) by simultaneously outputting two sounds (S1, S2) corresponding to different frequency ranges from the speaker unit (420). For example, the electronic device (400) can simultaneously output the first sound (S1) and the second sound (S2) to move foreign substances introduced into the conduit (415) to the outside of the electronic device (400). The simultaneous output of the first sound (S1) and the second sound (S2) can provide vibration and percussive force to move the foreign substances along the conduit (415) to the outside of the electronic device (400).

[0154] FIG. 8A and FIG. 8B are drawings showing an electronic device (400) according to one embodiment of the present disclosure.

[0155] Fig. 8a is a drawing showing a second side (410B) of a housing (410) according to one embodiment. Fig. 8b is a drawing showing an electronic device (400) viewed along line D-D' of Fig. 8a.

[0156] FIG. 8A may be a drawing that transparently illustrates a second surface (410B) of a housing (410). For example, FIG. 8A may be a drawing that transparently illustrates a second surface (410B) of a housing (410) and a speaker unit (420) disposed in the housing (410).

[0157] Referring to FIG. 8a, a speaker unit (420) can be placed in the housing (410).

[0158] In one embodiment, the speaker unit (420) may include a first speaker (421) and / or a second speaker (422).

[0159] In one embodiment, the first speaker (421) may be configured to simultaneously output a first sound (S1) and a second sound (S2). The first sound (S1) may correspond to a different frequency range than the second sound (S2). For example, the first sound (S1) may correspond to a first frequency range (fr1, see FIG. 10). The second sound (S2) may correspond to a second frequency range (fr2, see FIG. 11) that is different from the first frequency range (fr1, see FIG. 10).

[0160] In one embodiment, the second speaker (422) may be configured to simultaneously output a third sound (S3) and a fourth sound (S4). The third sound (S3) may correspond to a different frequency range than the fourth sound (S4). For example, the third sound (S3) may correspond to a first frequency range (fr1, see FIG. 10). The fourth sound (S4) may correspond to a second frequency range (fr2, see FIG. 11) that is different from the first frequency range (fr1, see FIG. 10). That is, the same speaker within the speaker unit (420) may simultaneously output two different sounds in different frequency ranges.

[0161] In one embodiment, the first speaker (421) and the second speaker (422) can output sound simultaneously. In one embodiment, while the first speaker (421) outputs sound, the second speaker (422) can also be set to output sound. For example, while the first speaker (421) outputs a first sound (S1) corresponding to a first frequency range (fr1, see FIG. 10) and / or a second sound (S2) corresponding to a second frequency range (fr2, see FIG. 11), the second speaker (422) can be set to output a third sound (S3) corresponding to the first frequency range (fr1, see FIG. 10) and / or a fourth sound (S4) corresponding to the second frequency range (fr2, see FIG. 11) for a specified period of time.

[0162] In one embodiment, the third sound (S3) may be substantially identical to the first sound (S1). In one embodiment, the fourth sound (S4) may be substantially identical to the second sound (S2). That is, the speaker unit (420) may output two or more identical sounds at two different locations along the speaker unit (420), for example, at the audio output of the first speaker (421) and the audio output of the second speaker (422).

[0163] In one embodiment, a conduit (415) may be formed between the speaker section (420) and the housing (410) and / or in at least a portion of the housing (410). For example, the conduit (415) may be formed in the space between the speaker section (420) and the housing (410).

[0164] In one embodiment, sound output from the speaker unit (420) can be transmitted to the outside of the electronic device (400) through the conduit (415).

[0165] In one embodiment, the conduit (415) may include a first conduit (4151), a second conduit (4152), and / or a common conduit (4153).

[0166] In one embodiment, the first conduit (4151) may be a conduit corresponding to the first speaker (421). For example, the first conduit (4151) may be a passage for transmitting sound output from the first speaker (421) to the outside of the electronic device (400).

[0167] In one embodiment, the second conduit (4152) may be a conduit corresponding to the second speaker (422). For example, the second conduit (4152) may be a passage for transmitting sound output from the second speaker (422) to the outside of the electronic device (400).

[0168] In one embodiment, the speaker unit (420) may be configured to output sound based at least in part on the insertion of a foreign substance into at least one conduit (415). For example, the speaker unit (420) may be configured to output sound based at least in part on the insertion of a foreign substance into at least one of the first conduit (4151) and the second conduit (4152).

[0169] In one embodiment, the first speaker (421) may be configured to output a first sound (S1) and / or a second sound (S2) for a specified period of time based at least in part on whether a foreign substance has been inserted into the first conduit (4151).

[0170] In one embodiment, the second speaker (422) may be configured to output a third sound (S3) and / or a fourth sound (S4) for a specified period of time based at least in part on the foreign body being inserted into the second conduit (4152).

[0171] In one embodiment, the first conduit (4151) and the second conduit (4152) may share at least a portion of the same area. For example, in one embodiment, the first conduit (4151) and / or the second conduit (4152) may include a common conduit (4153) shared with the first conduit (4151). The first conduit (4151) and the second conduit (4152) may be capable of voice communication and / or fluid communication with each other through the common conduit (4153).

[0172] In one embodiment, the common conduit (4153) may be a conduit formed between the housing (410) and the speaker unit (420). For example, the common conduit (4153) may be a space formed between the inner surface of the housing (410) and the speaker unit (420). For example, the inner surface of the housing (410) may be a surface of the housing (410) facing the speaker unit (420).

[0173] In one embodiment, the common conduit (4153) may correspond to the first speaker (421) and the second speaker (422), respectively. Sound output from the first speaker (421) and the second speaker (422) may pass through the common conduit (4153). The common conduit (4153) may enable mutual sound transmission and / or fluid transmission with each speaker within the speaker unit (420).

[0174] In one embodiment, the speaker section (420) may be configured to output sound based at least in part on the presence of a foreign substance inserted into the common conduit (4153).

[0175] In one embodiment, the second speaker (422) may be configured to output the third sound (S3) and / or the fourth sound (S4) for a specified period of time based at least in part on the foreign substance being inserted into the common conduit (4153). For example, the second speaker (422) may be configured to output the third sound (S3) corresponding to the first frequency range (fr1, see FIG. 10) and / or the fourth sound (S4) corresponding to the second frequency range (fr2, see FIG. 11) for a specified period of time while the first speaker (421) outputs the first sound (S1) corresponding to the first frequency range (fr1, see FIG. 10) and / or the second sound (S2) corresponding to the second frequency range (fr2, see FIG. 11) when the electronic device (400) detects that a foreign substance is inserted into the common conduit (4153) by a specified amount or more.

[0176] FIG. 9A and FIG. 9B are drawings showing an electronic device (900-1, 900-2) according to one embodiment of the present disclosure.

[0177] FIG. 9A is a drawing showing a first speaker (921-1) including a second speaker (922-1) according to one embodiment. FIG. 9B is a drawing showing a second speaker (922-2) positioned at a different location from the first speaker (921-2) according to one embodiment.

[0178] An electronic device (900-1) according to one embodiment may include a speaker unit (920) and / or a conduit (915).

[0179] In one embodiment, the speaker unit (920) may include a first speaker (921-1) and / or a second speaker (922-1).

[0180] Referring to FIG. 9A, a first speaker (921-1) according to one embodiment may include a second speaker (922-1). Alternatively, in one embodiment, the second speaker (922-1) may be formed as a separate speaker from the first speaker (921-1) and may be positioned to face the same direction.

[0181] In one embodiment, the first speaker (921-1) and the second speaker (922-1) may share a conduit (915). For example, sound output from the first speaker (921-1) and sound output from the second speaker (922-1) may be transmitted through a single conduit (915).

[0182] Referring to FIG. 9a, in one embodiment, the first speaker (921-1) and the second speaker (922-1) may be positioned in the same direction relative to the conduit (915).

[0183] Referring to FIG. 9b, in one embodiment, the speaker unit (920) may include a first speaker (921-2) and / or a second speaker (922-2).

[0184] According to one embodiment, the first speaker (921-2) may be a separate speaker from the second speaker (922-2).

[0185] In one embodiment, the first speaker (921-2) may be positioned facing the second speaker (922-2).

[0186] In one embodiment, the first speaker (921-2) and the second speaker (922-2) may share a conduit (915). For example, the sound output from the first speaker (921-2) and the sound output from the second speaker (922-2) may be transmitted through a single conduit (915).

[0187] Referring to FIG. 9B, in one embodiment, the first speaker (921-2) and the second speaker (922-2) may be positioned in different directions with respect to the conduit (915). For example, the first speaker (921-2) may be positioned in one direction with respect to the conduit (915), and the second speaker (922-2) may be positioned in the opposite direction with respect to the conduit (915).

[0188] In one embodiment, the electronic device (900) outputs sound (e.g., the first sound (1000) of FIG. 10) from the speaker unit (920) to remove foreign substances that have entered a single conduit (915) shared by multiple speakers.

[0189] In one embodiment, the electronic device (900) may include a vibration actuator (not shown). In one embodiment, the vibration actuator may be configured to operate based on the output of the speaker unit (920). For example, the vibration actuator may be configured to generate vibration while a sound (e.g., a first sound (1000, see FIG. 10) or a second sound (1100, see FIG. 11)) is output through the speaker unit (920).

[0190] FIG. 10 is a drawing showing a first sound (1000) according to one embodiment of the present disclosure.

[0191] A speaker unit (420, see FIG. 6A) according to one embodiment of the present disclosure can output a first sound (1000). For example, the speaker unit (420) can be set to perform an operation of outputting the first sound (1000) for a specified period of time.

[0192] In one embodiment, one speaker (e.g., first speaker (421), see FIG. 6a) may output a first sound (1000).

[0193] In one embodiment, multiple speakers can output the first sound (1000) simultaneously. For example, the first speaker (421, see FIG. 6A) and the second speaker (422, see FIG. 6A) can output the first sound (1000) simultaneously.

[0194] The first sound (1000) of FIG. 10 may refer to the first sound (S1) and / or the third sound (S3) of FIG. 8b, or may include the first sound (S1) and / or the third sound (S3) of FIG. 8b.

[0195] In one embodiment, the first sound (1000) may be a sound output from the speaker unit (420, see FIG. 6A). For example, the first sound (1000) may be a set of multiple sounds output from the speaker unit (420).

[0196] Referring to FIG. 10, a first sound (1000) according to one embodiment may include a first sub-sound (1010), a second sub-sound (1020), a third sub-sound (1030), and / or a fourth sub-sound (1040).

[0197] In FIG. 10, the first sound (1000) is illustrated as including four sub-sounds with different frequencies, but the number of sub-sounds included in the first sound (1000) may not be limited thereto. For example, the first sound (1000) may include three or fewer sub-sounds, or five or more sub-sounds.

[0198] In one embodiment, the first sound (1000) may correspond to a first frequency range (fr1). For example, the first sub-sound (1010), the second sub-sound (1020), the third sub-sound (1030), and / or the fourth sub-sound (1040) forming the first sound (1000) may be sounds within the first frequency range (fr1). For example, when the first frequency range (fr1) is approximately 100 Hz to 1000 Hz, the frequency of the first sub-sound (1010) may be approximately 200 Hz, the frequency of the second sub-sound (1020) may be approximately 400 Hz, the frequency of the third sub-sound (1030) may be approximately 600 Hz, and the frequency of the fourth sub-sound (1040) may be approximately 900 Hz.

[0199] In one embodiment, the first frequency range (fr1) may be a frequency range associated with a resonant frequency of a particular speaker (e.g., the first speaker (421) of FIG. 6B). For example, in one embodiment, the resonant frequency of the particular speaker (e.g., the first speaker (421) of FIG. 6B) may be a frequency within the first frequency range (fr1). Alternatively, in one embodiment, the resonant frequency of the speaker (e.g., the first speaker (421) of FIG. 6B) may be a frequency adjacent to the first frequency range (fr1).

[0200] In one embodiment, the first sound (1000) may be output so that each of the sub-sounds (1010, 1020, 1030, 1040) has a sound pressure level higher than a predetermined level. For example, referring to FIG. 10, the first sub-sound (1010), the second sub-sound (1020), the third sub-sound (1030), and the fourth sub-sound (1040) included in the first sound (1000) may each be output at a level higher than the first sound pressure level (P1).

[0201] In one embodiment, the first sub-sound (1010), the second sub-sound (1020), the third sub-sound (1030), and the fourth sub-sound (1040) may be sounds corresponding to different frequencies. The first sub-sound (1010), the second sub-sound (1020), the third sub-sound (1030), and the fourth sub-sound (1040) may be sounds corresponding to frequencies that are discretely distinct from each other. For example, the frequency of the first sub-sound (1010) may be approximately 200 Hz, the frequency of the second sub-sound (1020) may be approximately 400 Hz, the frequency of the third sub-sound (1030) may be approximately 600 Hz, and the frequency of the fourth sub-sound (1040) may be approximately 900 Hz.

[0202] In one embodiment, the first period (t1), the second period (t2), the third period (t3), and / or the fourth period (t4) may refer to different times.

[0203] In one embodiment, the first period (t1), the second period (t2), the third period (t3), and / or the fourth period (t4) may each be maintained for a specified length of time.

[0204] In one embodiment, the first sound (1000) may change in sound form over time. For example, the first sound (1000) may have different sound forms in the first period (t1), the second period (t2), the third period (t3), and the fourth period (t4). The first sound (1000) may output sound pressure of at least some sub-sounds (the first sub-sound (1010), the second sub-sound (1020), the third sub-sound (1030), or the fourth sub-sound (1040)) differently at each time point (e.g., the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4)).

[0205] In one embodiment, the first sound (1000) may change in the order of a first period (t1), a second period (t2), a third period (t3), or a fourth period (t4) over time. That is, in one embodiment, the first period (t1) may be the earliest time point, and the fourth period (t4) may be the latest time point. In this case, the first sound (1000) may have a sound form of the first period (t1) (e.g., a form in which only the first sub-sound (1010) is output with the second sound pressure (P2)) and then have a sound form of the second period (t2) (e.g., a form in which only the second sub-sound (1020) is output with the second sound pressure (P2)). The first sound (1000) may have a sound form of the second period (t2) and then a sound form of the third period (t3) (e.g., only the third sub-sound (1030) is output with the second sound pressure (P2)). The first sound (1000) may have a sound form of the third period (t3) and then a sound form of the fourth period (t4) (e.g., only the fourth sub-sound (1040) is output with the second sound pressure (P2)).

[0206] The first sound (1000) is not limited to changing in the order of the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4) over time, and the chronological relationship among the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4) can be formed in various ways. For example, in one embodiment, the first sound (1000) can change in the order of the fourth period (t4), the third period (t3), the second period (t2), or the first period (t1) over time. That is, in one embodiment, the fourth period (t4) can be the earliest time point, and the first period (t1) can be the latest time point.

[0207] In one embodiment, the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4) may represent mutually discontinuous time points. For example, the first sound (1000) may change to the second period (t2) after a set time has elapsed after the first period (t1).

[0208] In one embodiment, the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4) may represent mutually consecutive time points. For example, the first sound (1000) may change to the second period (t2) immediately after the first period (t1).

[0209] In one embodiment, the speaker unit (420, see FIG. 6A) may be configured to output the first sound (1000) such that the first sound (1000) discontinuously increases or decreases within a first frequency range (fr1). In one embodiment, the frequencies corresponding to the first sub-sound (1010), the second sub-sound (1020), the third sub-sound (1030), and the fourth sub-sound (1040) may be mutually discontinuous frequencies. For example, the frequency corresponding to the first sub-sound (1010) and the frequency corresponding to the second sub-sound (1020) may differ from each other by a predetermined value or more. The speaker unit (420) may be configured to output the first sound (1000) such that the frequency corresponding to a predetermined sound pressure (e.g., the second sound pressure (P2)) discontinuously increases or decreases within the first frequency range (fr1) over time.

[0210] In one embodiment, the speaker unit (420, see FIG. 6A) may be configured to output the first sound (1000) such that the first sound (1000) continuously increases or decreases within a first frequency range (fr1). In one embodiment, the frequencies corresponding to the first sub-sound (1010), the second sub-sound (1020), the third sub-sound (1030), and the fourth sub-sound (1040) may be mutually continuous frequencies. For example, the frequency corresponding to the first sub-sound (1010) and the frequency corresponding to the second sub-sound (1020) may differ by a predetermined value or less. The speaker unit (420) may be configured to output the first sound (1000) such that the frequency corresponding to a predetermined sound pressure (e.g., the second sound pressure (P2)) continuously increases or decreases within the first frequency range (fr1) over time.

[0211] In one embodiment, the sound pressure of the first sub-sound (1010), the second sub-sound (1020), the third sub-sound (1030), and the fourth sub-sound (1040) included in the first sound (1000) may be temporarily increased in a predetermined order. For example, at each time point (e.g., the first period (t1), the second period (t2), the third period (t3), and the fourth period (t4)), only the sound pressure of some of the multiple sounds included in the first sound (1000) may be increased. For example, at the first period (t1), only the sound pressure of the first sub-sound (1010) may be increased from the first sound pressure (P1) to the second sound pressure (P2), and at the second period (t2), only the sound pressure of the second sub-sound (1020) may be increased from the first sound pressure (P1) to the second sound pressure (P2). In the third period (t3), only the sound pressure of the third sub-sound (1030) can be increased from the first sound pressure (P1) to the second sound pressure (P2). In the fourth period (t4), only the sound pressure of the fourth sub-sound (1040) can be increased from the first sound pressure (P1) to the second sound pressure (P2).

[0212] In one embodiment, the sound pressure of the first sub-sound (1010), the second sub-sound (1020), the third sub-sound (1030), and the fourth sub-sound (1040) included in the first sound (1000) may temporarily increase at a predetermined time point. In one embodiment, the sound pressure of only one sound among the plurality of sounds may temporarily increase at each time point (e.g., the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4)). For example, the sound pressure of the first sub-sound (1010) may temporarily increase to the second sound pressure (P2) at the first period (t1), and may be maintained at the first sound pressure (P1) level at the second period (t2), the third period (t3), and the fourth period (t4). The sound pressure of the second sub-sound (1020) may be maintained at the first sound pressure (P1) level in the first period (t1), the third period (t3), and the fourth period (t4), and may temporarily increase to the second sound pressure (P2) in the second period (t2). The sound pressure of the third sub-sound (1030) may be maintained at the first sound pressure (P1) level in the first period (t1), the second period (t2), and the fourth period (t4), and may temporarily increase to the second sound pressure (P2) in the third period (t3). The sound pressure of the fourth sub-sound (1040) may be maintained at the first sound pressure (P1) level in the first period (t1), the second period (t2), and the third period (t3), and may temporarily increase to the second sound pressure (P2) in the fourth period (t4).

[0213] In one embodiment, the first sound (1000) may include a plurality of sub-sounds (1010, 1020, 1030, 1040) having different frequencies. The plurality of speakers (421, 422, see FIG. 6A) may be configured to output a sound pressure of any one of the plurality of sub-sounds of the first sound (1000) to be louder than the sound pressure of the remaining sub-sounds of the first sound (1000).

[0214] In one embodiment, the plurality of sub-sounds of the first sound (1000) may include a first sub-sound (1010), a second sub-sound (1020), a third sub-sound (1030), and a fourth sub-sound (1040) having different frequencies. The plurality of speakers (421, 422, see FIG. 6A) may be configured to alternately output the first sub-sound (1010), the second sub-sound (1020), the third sub-sound (1030), and the fourth sub-sound (1040) at a greater sound pressure than the other sub-sounds.

[0215] In one embodiment, a plurality of speakers (421, 422, see FIG. 6A) may be configured such that a first sub-sound (1010), a second sub-sound (1020), a third sub-sound (1030), and a fourth sub-sound (1040) are each output at a first sound pressure (P1) or higher, and one of the first sub-sound (1010), the second sub-sound (1020), the third sub-sound (1030), and the fourth sub-sound (1040) is output at a second sound pressure (P2) that is greater than the first sound pressure (P1).

[0216] In one embodiment, the speaker unit (420, see FIG. 8B) can output a first sound (1000) to remove foreign substances inserted into the conduit (415, see FIG. 8B) or near the speaker unit (420). For example, the speaker unit (420) can output the first sound (1000) to move foreign substances introduced into the conduit (415) to the outside of the electronic device (400).

[0217] In one embodiment, when the first sound (1000) is output simultaneously from multiple speakers (421, 422, see FIG. 6a), the effect of removing foreign substances can be further improved compared to when the first sound (1000) is output from a single speaker.

[0218] FIG. 11 is a diagram illustrating a second sound (1100) according to one embodiment of the present disclosure.

[0219] A speaker unit (420, see FIG. 6A) according to one embodiment of the present disclosure can output a second sound (1100). For example, in one embodiment, the speaker unit (420) can be set to perform an operation of outputting the second sound (1100) for a specified period of time.

[0220] In one embodiment, the speaker unit (420, see FIG. 6A) can output a second sound (1100) to remove foreign substances that have entered the conduit (415). For example, the speaker unit (420) can output a second sound (1100) to move water that has entered the conduit (415) to the outside of the electronic device (400).

[0221] In one embodiment, one speaker (e.g., first speaker (421), see FIG. 6a) may output a second sound (1100).

[0222] In one embodiment, multiple speakers can output the second sound (1100) simultaneously. For example, a first speaker (421, see FIG. 6A) and a second speaker (422, see FIG. 6A) can output the second sound (1100) simultaneously.

[0223] The second sound (1100) of FIG. 11 may refer to the second sound (S2) and / or the fourth sound (S4) of FIG. 8b, or may include the second sound (S2) and / or the fourth sound (S4) of FIG. 8b.

[0224] In one embodiment, the second sound (1100) may be a sound output from the speaker unit (420, see FIG. 6A). For example, the second sound (1100) may be a set of multiple sounds output from the speaker unit (420).

[0225] Referring to FIG. 11, the second sound (1100) according to one embodiment may include a fifth sub-sound (1110), a sixth sub-sound (1120), a seventh sub-sound (1130), and / or an eighth sub-sound (1140).

[0226] In FIG. 11, the second sound (1100) is illustrated as including four sub-sounds with different frequencies, but the number of sub-sounds included in the second sound (1100) may not be limited thereto. For example, the second sound (1100) may include three or fewer sub-sounds, or five or more sub-sounds.

[0227] In one embodiment, the second sound (1100) may correspond to a second frequency range (fr2). For example, the fifth sub-sound (1110), the sixth sub-sound (1120), the seventh sub-sound (1130), and the eighth sub-sound (1140) forming the second sound (1100) may be sounds within the second frequency range (fr2). For example, when the second frequency range (fr2) is approximately 0.5 kHz to 5 kHz, the frequency of the fifth sub-sound (1110) may be approximately 1 kHz, the frequency of the sixth sub-sound (1120) may be approximately 2 kHz, the frequency of the seventh sub-sound (1130) may be approximately 3 kHz, and the frequency of the eighth sub-sound (1140) may be approximately 4 kHz.

[0228] In one embodiment, the second frequency range (fr2) may be at least partially different from the first frequency range (fr1) of FIG. 10.

[0229] In one embodiment, the second frequency range (fr2) may be a frequency range associated with a resonant frequency of a particular speaker (e.g., the second speaker (422) of FIG. 6B). For example, in one embodiment, the resonant frequency of the particular speaker (e.g., the second speaker (422) of FIG. 6B) may be a frequency within the second frequency range (fr2). Alternatively, in one embodiment, the resonant frequency of the particular speaker (e.g., the second speaker (422) of FIG. 6B) may be a frequency adjacent to the second frequency range (fr2).

[0230] In one embodiment, the first frequency range (fr1, see FIG. 10) and the second frequency range (fr2) may be formed continuously. For example, the first frequency range (fr1, see FIG. 10) may include at least a portion of the second frequency range (fr2) or may be a frequency range connected to the second frequency range (fr2). Alternatively, in one embodiment, the frequency corresponding to the first frequency range (fr1, see FIG. 10) and the frequency corresponding to the second frequency range (fr2) may differ from each other by a predetermined value or less.

[0231] In one embodiment, the second sound (1100) may be output so that each sub-sound (1110, 1120, 1130, 1140) has a sound pressure level higher than a predetermined level. For example, referring to FIG. 11, the fifth sub-sound (1110), the sixth sub-sound (1120), the seventh sub-sound (1130), and the eighth sub-sound (1140) included in the second sound (1100) may each be output at a sound pressure level higher than a third sound pressure level (P3).

[0232] In one embodiment, the fifth sub-sound (1110), the sixth sub-sound (1120), the seventh sub-sound (1130), and the eighth sub-sound (1140) may be sounds corresponding to different frequencies. The fifth sub-sound (1110), the sixth sub-sound (1120), the seventh sub-sound (1130), and the eighth sub-sound (1140) may be sounds corresponding to frequencies that are discretely distinct from each other. For example, the frequency of the fifth sub-sound (1110) may be approximately 1 kHz, and the frequency of the sixth sub-sound (1120) may be approximately 2 kHz. The frequency of the seventh sub-sound (1130) may be approximately 3 kHz, and the frequency of the eighth sub-sound (1140) may be approximately 4 kHz.

[0233] In one embodiment, the first period (t1), the second period (t2), the third period (t3), and the fourth period (t4) may refer to different times.

[0234] In one embodiment, the first period (t1), the second period (t2), the third period (t3), and the fourth period (t4) may each be maintained for a specified length of time.

[0235] In one embodiment, the second sound (1100) may change in sound form over time. For example, the second sound (1100) may have different sound forms in the first period (t1), the second period (t2), the third period (t3), and the fourth period (t4). The second sound (1100) may output sound pressure of at least some sounds (the fifth sub-sound (1110), the sixth sub-sound (1120), the seventh sub-sound (1130), or the eighth sub-sound (1140)) differently at each time point (e.g., the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4)).

[0236] In one embodiment, the second sound (1100) may change in the order of the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4) over time. That is, in one embodiment, the first period (t1) may be the earliest time point, and the fourth period (t4) may be the latest time point. In this case, the second sound (1100) may have the sound form of the first period (t1) (e.g., only the fifth sub-sound (1110) is output at the fourth sound pressure (P4)) and then have the sound form of the second period (t2) (e.g., only the sixth sub-sound (1120) is output at the fourth sound pressure (P4)). The second sound (1100) may have a sound form of the second period (t2) and then a sound form of the third period (t3) (e.g., only the seventh sub-sound (1130) is output with the fourth sound pressure (P4)). The second sound (1100) may have a sound form of the third period (t3) and then a sound form of the fourth period (t4) (e.g., only the eighth sub-sound (1140) is output with the fourth sound pressure (P4)).

[0237] The second sound (1100) is not limited to changing in the order of the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4) over time, and the chronological relationship among the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4) can be formed in various ways. For example, the second sound (1100) can change in the order of the fourth period (t4), the third period (t3), the second period (t2), or the first period (t1) over time. That is, in one embodiment, the fourth period (t4) can be the earliest time point, and the first period (t1) can be the latest time point.

[0238] In one embodiment, the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4) may represent mutually discontinuous time points. For example, the second sound (1100) may change to the second period (t2) after a set time has elapsed after the first period (t1).

[0239] In one embodiment, the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4) may represent mutually consecutive time points. For example, the second sound (1100) may change to the second period (t2) immediately after the first period (t1).

[0240] In one embodiment, the speaker unit (420, see FIG. 6A) may be configured to output the second sound (1100) such that the second sound (1100) discontinuously increases or decreases within a second frequency range (fr2). In one embodiment, the frequencies corresponding to the fifth sub-sound (1110), the sixth sub-sound (1120), the seventh sub-sound (1130), and the eighth sub-sound (1140) may be mutually discontinuous frequencies. For example, the frequency corresponding to the fifth sub-sound (1110) and the frequency corresponding to the sixth sub-sound (1120) may differ from each other by a predetermined value or more. The speaker unit (420) may be configured to output the second sound (1100) such that the frequency corresponding to a predetermined sound pressure (e.g., the fourth sound pressure (P4)) discontinuously increases or decreases within the second frequency range (fr2) over time.

[0241] In one embodiment, the speaker unit (420, see FIG. 6A) may be configured to output the second sound (1100) such that the second sound (1100) continuously increases or decreases within the second frequency range (fr2). In one embodiment, the frequencies corresponding to the fifth sub-sound (1110), the sixth sub-sound (1120), the seventh sub-sound (1130), and the eighth sub-sound (1140) may be mutually continuous frequencies. For example, the frequency corresponding to the fifth sub-sound (1110) and the frequency corresponding to the sixth sub-sound (1120) may differ by a predetermined value or less. The speaker unit (420) may be configured to output the second sound (1100) such that the frequency corresponding to a predetermined sound pressure (e.g., the fourth sound pressure (P4)) continuously increases or decreases within the second frequency range (fr2) over time.

[0242] In one embodiment, the sound pressure of the fifth sub-sound (1110), the sixth sub-sound (1120), the seventh sub-sound (1130), and the eighth sub-sound (1140) included in the second sound (1100) may be temporarily increased in a predetermined order. For example, at each time point (e.g., the first time point (t1), the second time point (t2), the third time point (t3), or the fourth time point (t4)), only the sound pressure of some of the multiple sounds included in the second sound (1100) may be increased. For example, at the first time point (t1), only the sound pressure of the fifth sub-sound (1110) may be increased from the third sound pressure (P3) to the fourth sound pressure (P4), and at the second time point (t2), only the sound pressure of the sixth sub-sound (1120) may be increased from the third sound pressure (P3) to the fourth sound pressure (P4). In the third period (t3), only the sound pressure of the seventh sub-sound (1130) can be increased from the third sound pressure (P3) to the fourth sound pressure (P4). In the fourth period (t4), only the sound pressure of the eighth sub-sound (1140) can be increased from the third sound pressure (P3) to the fourth sound pressure (P4).

[0243] In one embodiment, the sound pressure of the fifth sub-sound (1110), the sixth sub-sound (1120), the seventh sub-sound (1130), and the eighth sub-sound (1140) included in the second sound (1100) may temporarily increase at a predetermined time point. In one embodiment, the sound pressure of only one sound may temporarily increase at each time point (e.g., the first period (t1), the second period (t2), the third period (t3), or the fourth period (t4)). For example, the sound pressure of the fifth sub-sound (1110) may temporarily increase to the fourth sound pressure (P4) at the first period (t1), and may be maintained at the third sound pressure (P3) level at the second period (t2), the third period (t3), and the fourth period (t4). The sound pressure of the sixth sub-sound (1120) may be maintained at the third sound pressure (P3) level in the first period (t1), the third period (t3), and the fourth period (t4), and may temporarily increase to the fourth sound pressure (P4) in the second period (t2). The sound pressure of the seventh sub-sound (1130) may be maintained at the third sound pressure (P3) level in the first period (t1), the second period (t2), and the fourth period (t4), and may temporarily increase to the fourth sound pressure (P4) in the third period (t3). The sound pressure of the eighth sub-sound (1140) may be maintained at the third sound pressure (P3) level in the first period (t1), the second period (t2), and the third period (t3), and may temporarily increase to the fourth sound pressure (P4) in the fourth period (t4).

[0244] In one embodiment, the second sound (1100) may include a plurality of sub-sounds (1110, 1120, 1130, 1140) having different frequencies. The plurality of speakers (421, 422, see FIG. 6A) may be configured to output a sound pressure of any one of the plurality of sub-sounds of the second sound (1100) to be greater than the sound pressure of the remaining sub-sounds of the second sound (1100).

[0245] In one embodiment, the plurality of sub-sounds of the second sound (1100) may include a fifth sub-sound (1110), a sixth sub-sound (1120), a seventh sub-sound (1130), and an eighth sub-sound (1140) having different frequencies. The plurality of speakers (421, 422, see FIG. 6A) may be configured to alternately output the fifth sub-sound (1110), the sixth sub-sound (1120), the seventh sub-sound (1130), and the eighth sub-sound (1140) at a greater sound pressure than the other sub-sounds.

[0246] In one embodiment, a plurality of speakers (421, 422, see FIG. 6A) may be configured such that the fifth sub-sound (1110), the sixth sub-sound (1120), the seventh sub-sound (1130), and the eighth sub-sound (1140) are each output at a third sound pressure (P3) or higher, and one of the fifth sub-sound (1110), the sixth sub-sound (1120), the seventh sub-sound (1130), and the eighth sub-sound (1140) is output at a fourth sound pressure (P4) that is greater than the third sound pressure (P3).

[0247] In one embodiment, the second sound (1100) may be output with the same phase as the first sound (1000) of FIG. 10. For example, the first period (t1), the second period (t2), the third period (t3), and the fourth period (t4) at which the second sound (1100) is output may be substantially the same as the first period (t1), the second period (t2), the third period (t3), and the fourth period (t4) at which the first sound (1000) of FIG. 10 is output, respectively.

[0248] In one embodiment, one speaker (e.g., first speaker (421), see FIG. 6a) can output a first sound (1000) and a second sound (1100) in the same phase.

[0249] In one embodiment, multiple speakers can each output multiple sounds with the same phase. For example, a first speaker (421, see FIG. 6A) and a second speaker (422, see FIG. 6A) can each output a first sound (1000, see FIG. 10) and a second sound (1100) with the same phase.

[0250] In one embodiment, the speaker unit (420, see FIG. 8b) can output a first sound (1000, see FIG. 6a) and a second sound (1100) to remove foreign substances inserted into the conduit (415, see FIG. 8b) or near the speaker unit (420). For example, the speaker unit (420) can output the first sound (1000) and the second sound (1100) to move foreign substances introduced into the conduit (415) to the outside of the electronic device (400).

[0251] In one embodiment, when multiple speakers output multiple sounds with the same phase, the effect of removing foreign substances can be further improved compared to when multiple speakers output only one sound.

[0252] FIG. 12a and FIG. 12b are diagrams showing negative pressure graphs (1201, 1202) according to one embodiment of the present disclosure.

[0253] Fig. 12a is a first graph (1201) showing sound pressure according to frequency when a first sound (1201a) is output. Fig. 12b is a second graph (1202) showing sound pressure according to frequency when a first sound (1202a) and a second sound (1202b) are output simultaneously.

[0254] In the first graph (1201) of FIG. 12a and the second graph (1202) of FIG. 12b, the horizontal axis (f) may represent the frequency of the sound. The vertical axis (dB) may represent the sound pressure level of the sound.

[0255] Referring to the first graph (1201) of FIG. 12a, a first sound (1201a) may be output from a speaker unit (e.g., speaker unit (420) of FIG. 6a). The first sound (1201a) may refer to the first sound (1000) of FIG. 10 or may include at least a part of the first sound (1000) of FIG. 10.

[0256] In one embodiment, the first sound (1201a) may correspond to a first frequency range (fr1). For example, referring to the first graph (1201) of FIG. 12A, the first sound (1201a) may have a frequency within the first frequency range (fr1).

[0257] In one embodiment, the first sound (1201a) may have a varying sound pressure within a given frequency range. For example, in one embodiment, the first sound (1201a) may be output to have multiple local peaks within the first frequency range (fr1). Referring to the first graph (1201) of FIG. 12A, the first sound (1201a) may form multiple local peaks of sound pressure at different frequencies (f) within the first frequency range (fr1).

[0258] In one embodiment, when a first sound (1201a) corresponding to a first frequency range (fr1) is output from a speaker section (e.g., speaker section (420) of FIG. 6a), foreign matter introduced into a conduit (415, see FIG. 8b) of an electronic device (400, see FIG. 8b) can be removed.

[0259] Referring to the second graph (1202) of FIG. 12b, a first sound (1202a) and a second sound (1202b) may be simultaneously output from a speaker unit (e.g., speaker unit (420) of FIG. 6a). The first sound (1202a) may refer to the first sound (1000) of FIG. 10 or may include at least a portion of the first sound (1000) of FIG. 10. The second sound (1202b) may refer to the second sound (1100) of FIG. 11 or may include at least a portion of the second sound (1100) of FIG. 11.

[0260] In one embodiment, the first sound (1202a) may correspond to a first frequency range (fr1). For example, referring to the second graph (1202) of FIG. 12B , the first sound (1202a) may have a frequency within the first frequency range (fr1).

[0261] In one embodiment, the second sound (1202b) may correspond to a second frequency range (fr2). For example, referring to the second graph (1202) of FIG. 12b, the second sound (1202b) may have a frequency within the second frequency range (fr2).

[0262] In one embodiment, when a first sound (1202a) corresponding to a first frequency range (fr1) and a second sound (1202b) corresponding to a second frequency range (fr2) are simultaneously output from a speaker (e.g., speaker unit (420) of FIG. 6a), foreign substances introduced into a conduit (415, see FIG. 8b) of an electronic device (400, see FIG. 8b) can be more effectively removed. The first sound (1202a) and the second sound (1202b) can be simultaneously output so as to have multiple local peaks (e.g., eight peaks illustrated in FIG. 12b) within the first frequency range (fr1) and the second frequency range (fr2). Referring to the second graph (1202) of FIG. 12b, the first sound (1201a) and the second sound (1202b) can form a greater number of local peaks at different frequencies f.

[0263] FIG. 13 is a diagram illustrating an acoustic signal output method (1300) according to one embodiment of the present disclosure.

[0264] In one embodiment, the sound signal output method (1300) may be performed according to, for example, the flowchart illustrated in FIG. 13. The flowchart illustrated in FIG. 13 is merely a flowchart according to one embodiment of the sound signal output method (1300), and therefore, the order of each operation may be changed, or each operation may be performed simultaneously.

[0265] In one embodiment, each operation of the sound signal output method (1300) may be performed under the control of a processor of the electronic device (400) (e.g., processor (120) of FIG. 1).

[0266] In one embodiment, the sound signal output method (1300) may include an sound signal output function execution operation (1310), a primary sound signal output operation (1320) from one speaker, and / or a secondary sound signal output operation (1330) from one speaker.

[0267] In one embodiment, the electronic device (400) may be configured to execute a function of outputting sound through a speaker (e.g., a first speaker (421)) to remove foreign substances that have entered the conduit (415) in the sound signal output function execution operation (1310).

[0268] In one embodiment, removal of foreign matter introduced into the conduit (415) may include moving the introduced foreign matter to the outside of the electronic device (400) through sound and / or drying the introduced foreign matter (e.g., water) through heat generation.

[0269] In one embodiment, the electronic device (400) may be configured to perform an audio signal output function execution operation (1310) based on the occurrence of an event. For example, the electronic device (400) may be configured to automatically perform the audio signal output function execution operation (1310) when a predetermined mode (e.g., waterproof mode) is set and then released. In one embodiment, the electronic device (400) may be configured to perform the audio signal output function execution operation (1310) by detecting that a foreign substance has entered the conduit (415) through a detection sensor. In one embodiment, the electronic device (400) may be configured to perform the audio signal output function execution operation (1310) by recognizing the surrounding environment of the electronic device (400). In one embodiment, the electronic device (400) may be configured to perform the audio signal output function execution operation (1310) by recognizing the state of a speaker (e.g., a first speaker (421)). In one embodiment, the electronic device (400) may be configured to perform an acoustic signal output function execution operation (1310) based at least in part on a specified user input.

[0270] In one embodiment, the electronic device (400) may perform a primary audio signal output operation (1320) from one speaker when the audio signal output function execution operation (1310) is performed.

[0271] In one embodiment, the electronic device (400) may output a primary audio signal for a specified period of time through one speaker (e.g., a first speaker (421)) in a primary audio signal output operation (1320) from one speaker. In one embodiment, the primary audio signal may include at least one sound. For example, the primary audio signal may include a first sound (1000) and / or a second sound (1100).

[0272] In one embodiment, the primary acoustic signal may be a signal to remove foreign matter that has entered the conduit (415). For example, a speaker (e.g., the first speaker (421)) may push foreign matter that has entered the conduit (415) out of the electronic device (400) through the primary acoustic signal.

[0273] In one embodiment, the electronic device (400) may perform a primary audio signal output operation (1320) from one speaker and then perform a secondary audio signal output operation (1330) from one speaker.

[0274] In one embodiment, the electronic device (400) may output a secondary audio signal from one speaker (e.g., a first speaker (421)) for a specified period of time in a secondary audio signal output operation (1330) from one speaker. The secondary audio signal may be a different signal from the primary audio signal (e.g., the first sound (1000) or the second sound (1100)). For example, the primary audio signal may be a sound within an audible frequency range that a person can hear, and the secondary audio signal may be a sound within an inaudible frequency range that a person has difficulty hearing (e.g., 19 to 20 kHz, 20 to 50 kHz).

[0275] In one embodiment, the secondary acoustic signal may be a signal for removing foreign substances remaining in the conduit (415) through heat. For example, a speaker (e.g., the first speaker (421)) may output the secondary acoustic signal to generate heat. Foreign substances (e.g., water) remaining in the conduit (415) after the primary acoustic signal is output may be removed (e.g., evaporated) by the heat generated by the secondary acoustic signal.

[0276] In one embodiment, a secondary sound signal output from a second sound signal output operation (1330) from one speaker may be output for a longer time than a primary sound signal (e.g., a first sound (1000) or a second sound (1100)).

[0277] In one embodiment, the secondary audio signal is a sound within an inaudible frequency range that the user cannot hear, so even if it is output for a longer period of time compared to the primary audio signal, it may not interfere with the user's use of the electronic device (400).

[0278] FIG. 14 is a diagram illustrating an acoustic signal output method (1400) according to one embodiment of the present disclosure.

[0279] In one embodiment, the sound signal output method (1400) may be performed according to, for example, the flowchart illustrated in FIG. 14. The flowchart illustrated in FIG. 14 is merely a flowchart according to one embodiment of the sound signal output method (1400), and therefore, the order of each operation may be changed, or each operation may be performed simultaneously.

[0280] In one embodiment, each operation of the sound signal output method (1400) may be performed under the control of a processor of the electronic device (400) (e.g., processor (120) of FIG. 1).

[0281] In one embodiment, the sound signal output method (1400) may include an sound signal output function execution operation (1410), a primary sound signal output operation (1420) from a plurality of speakers, and / or a secondary sound signal output operation (1430) from a plurality of speakers.

[0282] The sound signal output function execution operation (1410) of FIG. 14 may be substantially the same operation as the sound signal output function execution operation (1310) of FIG. 13. In explaining the operation of the sound signal output method (1400) of FIG. 14, a description of an operation that is substantially the same as the operation of the sound signal output method (1300) of FIG. 13 may be omitted.

[0283] In one embodiment, the electronic device (400) may perform a primary audio signal output operation (1420) from multiple speakers when the audio signal output function execution operation (1410) is performed.

[0284] In one embodiment, the electronic device (400) may output a primary audio signal through a plurality of speakers (e.g., a first speaker (421) and a second speaker (422)) for a specified period of time in a primary audio signal output operation (1420). In one embodiment, the primary audio signal may include at least one sound. For example, the primary audio signal may include a first sound (1000) and / or a second sound (1100).

[0285] In one embodiment, in the primary sound signal output operation (1420) from multiple speakers, the number of sounds output from the multiple speakers (e.g., the first speaker (421) and the second speaker (422)) may vary based on the characteristics of the multiple speakers. For example, the number of sounds output from the multiple speakers may be substantially the same as the number of speakers having substantially different characteristics. In one embodiment, when N speakers each have different characteristics (e.g., resonant frequencies of the speakers), N sounds may be output from the N speakers simultaneously, respectively. For example, when there are two speakers and the two speakers have different characteristics, two sounds (e.g., the first sound (1000) or the second sound (1100)) may be output from the two speakers (e.g., the first speaker (421) or the second speaker (422)) simultaneously, respectively. In one embodiment, if two of the N speakers are substantially identical, N-1 sounds can be output simultaneously from each of the N speakers. For example, if there are three speakers, and two of the speakers are substantially identical, two sounds can be output simultaneously from each of the three speakers.

[0286] In one embodiment, the electronic device (400) may perform a primary audio signal output operation (1420) from a plurality of speakers, and then perform a secondary audio signal output operation (1430) from a plurality of speakers.

[0287] In one embodiment, the electronic device (400) may output a secondary audio signal from a plurality of speakers (e.g., a first speaker (421) and a second speaker (422)) for a specified period of time in a secondary audio signal output operation (1430) from a plurality of speakers. The secondary audio signal may be a different signal from the primary audio signal (e.g., the first sound (1000) or the second sound (1100)). For example, the primary audio signal may be a sound within an audible frequency range that a person can hear, and the secondary audio signal may be a sound within an inaudible frequency range that a person has difficulty hearing.

[0288] In one embodiment, the electronic device (400) can alleviate the heat generation limit of the speaker unit (420) in the first sound signal output operation (1320, 1420) and the second sound signal output operation (1330, 1430). For example, the electronic device (400) can further increase the maximum temperature that the coil of the speaker unit (420) can reach when the first sound signal output operation (1320, 1420) and the second sound signal output operation (1330, 1430) are performed. For example, the electronic device (400) can increase the maximum temperature that the coil of the speaker unit (420) can reach from approximately 110 degrees to approximately 120 degrees when the first sound signal output operation (1320, 1420) and the second sound signal output operation (1330, 1430) are performed.

[0289] In one embodiment, when the electronic device (400) performs both the primary sound signal output operation (1320, 1420) and the secondary sound signal output operation (1330, 1430) from a plurality of speakers, the effect of removing foreign substances introduced into the conduit (415) can be further improved compared to when only the primary sound signal (1320, 1420) is output from one or a plurality of speakers.

[0290] In one embodiment, when the electronic device (400) outputs sound from multiple speakers, the effect of removing foreign substances introduced into the conduit (415) may be further improved compared to when the sound is output from only one speaker. For example, when the electronic device (400) outputs sound from multiple speakers according to the sound signal output method (1400) of FIG. 14, the effect of removing foreign substances introduced into the conduit (415) may be further improved compared to when the sound is output from one speaker according to the sound signal output method (1300) of FIG. 13.

[0291] Fig. 15 is a drawing showing an acoustic signal output method (1500) based on foreign substance detection.

[0292] In one embodiment, the method (1500) for outputting an acoustic signal based on foreign substance detection may be performed according to, for example, the flowchart illustrated in FIG. 15. The flowchart illustrated in FIG. 15 is merely a flowchart according to one embodiment of the method (1500) for outputting an acoustic signal based on foreign substance detection, and therefore, the order of each operation may be changed, or each operation may be performed simultaneously.

[0293] In one embodiment, each operation of the method (1500) for outputting an acoustic signal based on foreign substance detection may be performed under the control of a processor of the electronic device (400) (e.g., processor (120) of FIG. 1).

[0296] In one embodiment, the electronic device (400) may perform a primary acoustic signal output operation (1520) based at least in part on the foreign substance detection operation (1510). For example, if a sensor of the electronic device (400) detects that a foreign substance has been inserted into the conduit (415) or near the speaker unit (420) in the foreign substance detection operation (1510), the electronic device (400) may perform the primary acoustic signal output operation (1520).

[0297] In one embodiment, the electronic device (400) may perform a primary acoustic signal output operation (1520) based at least in part on the amount of foreign matter detected in the foreign matter detection operation (1510). For example, if the electronic device (400) determines that the amount of foreign matter inserted near the conduit (415) or the speaker unit (420) is greater than a predetermined amount in the foreign matter detection operation (1510), the electronic device (400) may perform the primary acoustic signal output operation (1520). In one embodiment, the electronic device (400) may include a measurement sensor that measures the amount of foreign matter inserted near the conduit (415) or the speaker unit (420).

[0298] In one embodiment, the electronic device (400) may output a primary audio signal for a specified period of time through the speaker unit (420) in a primary audio signal output operation (1520).

Alternatively, the speaker unit (420) may be set to output the first sound (1000) and / or the second sound (1100) such that the size of at least one of the first sound (1000) or the second sound (1100) is adjusted based at least in part on the amount of foreign matter detected in the foreign matter detection operation (1510) in the first sound signal output operation (1520).

[0300] In one embodiment, the speaker unit (420) may be configured to increase or decrease a designated time for outputting a primary sound signal (e.g., a first sound (1000) or a second sound (1100)) based at least in part on the amount of foreign matter detected in the foreign matter detection operation (1510) in the primary sound signal output operation (1520).

[0301] In one embodiment, the electronic device (400) may perform a secondary audio signal output operation (1530) after performing a primary audio signal output operation (1520).

[0302] In one embodiment, the electronic device (400) may output a secondary audio signal from the speaker unit (420) for a specified period of time in the secondary audio signal output operation (1530). The secondary audio signal may be a different signal from the primary audio signal (e.g., the first sound (1000) or the second sound (1100)). For example, the primary audio signal may be a sound within an audible frequency range that a person can hear, and the secondary audio signal may be a sound within an inaudible frequency range that a person has difficulty hearing.

[0303] In one embodiment, the secondary sound signal output in the secondary sound signal output operation (1530) may be output for a longer time than the primary sound signal (e.g., first sound (1000), second sound (1100)) output in the primary sound signal output operation (1520).

[0304] Fig. 16 is a drawing showing a method (1600) for outputting an acoustic signal based on the surrounding environment.

[0305] In one embodiment, the method (1600) for outputting an acoustic signal based on the surrounding environment may be performed according to, for example, the flowchart illustrated in FIG. 16. The flowchart illustrated in FIG. 16 is merely a flowchart according to one embodiment of the method (1600) for outputting an acoustic signal based on the surrounding environment, and therefore, the order of each operation may be changed, or each operation may be performed simultaneously.

[0306] In one embodiment, each operation of the method for outputting an acoustic signal based on the surrounding environment (1600) may be performed under the control of a processor of the electronic device (400) (e.g., processor (120) of FIG. 1).

[0308] In one embodiment, the electronic device (400) may recognize the surrounding environment of the electronic device (400) in the operation of recognizing the surrounding environment of the electronic device (1610). The surrounding environment of the electronic device (400) may include the noise level around the electronic device (400) or the current location of the electronic device (400). In one embodiment, in operation 1610, the electronic device (400) may recognize the noise level around the electronic device (400) (e.g., the sound pressure level around the electronic device (400). In one embodiment, in operation 1610, the electronic device (400) may recognize the current location of the electronic device (400). For example, the electronic device (400) may recognize whether the electronic device (400) is in a place where the surrounding sound is relatively quiet (e.g., a library) or a place where the surrounding sound is relatively loud (e.g., a stadium or a concert hall).

[0309] In one embodiment, the electronic device (400) may perform an operation of recognizing the surrounding environment of the electronic device (1610) after performing the operation of executing the sound signal output function (1310) of FIG. 13, the operation of executing the sound signal output function (1410) of FIG. 14, or the operation of detecting a foreign substance (1510) of FIG. 15. For example, in one embodiment, the electronic device (400) may be configured to perform a function of outputting a sound signal for removing a foreign substance that has entered the conduit (415) through the operation of executing the sound signal output function (1310, 1410), and then perform the operation of recognizing the surrounding environment of the electronic device (400) to recognize the surrounding environment of the electronic device (400).

The electronic device (400) may be configured to vary the secondary audio signal output operation (1730) depending on the state of the speaker recognized in the speaker state recognition operation (1710). For example, if the electronic device (400) determines that the state of the speaker recognized in the speaker state recognition operation (1710) is higher than a predetermined standard (e.g., the age of the speaker is higher than the predetermined standard), the electronic device (400) may output the secondary audio signal for a longer period of time (e.g., output the secondary audio signal for a longer period) in the secondary audio signal output operation (1730).
