Description

Wearable electronic devices including acoustic devices

[0001] Various embodiments disclosed in this document relate to a wearable electronic device including an acoustic device.

[0002] Electronic devices may include wearable electronic devices that can be worn on a part of the user's body to enhance portability or accessibility. Wearable electronic devices may include ear-worn electronic devices that are worn on the user's ears to enable listening to music or provide convenience in making phone calls.

[0003] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above-described matters constitute prior art related to the present disclosure.

[0004] Wearable electronic devices (e.g., wireless earphones) can be worn on a user's ear (e.g., external auditory meatus). The wearable electronic devices can receive voice and / or sound from an external source or output sound to an external source using a microphone and a speaker. For example, the wearable electronic devices can process voice and / or sound input through the microphone into electrical signals, convert the electrical signals into sound, and output the converted signals through the speaker.

[0005] Meanwhile, as wireless earphones become increasingly smaller, the distance between the microphone and the user's mouth may increase when worn on the ear. This reduces the volume of the user's voice that can be picked up by the wireless earphone microphone, potentially degrading call quality.

[0006] The technical tasks to be achieved in this document are not limited to the technical tasks mentioned above, and other technical tasks not mentioned can be clearly understood by a person having ordinary knowledge in the technical field to which this document belongs from the description below.

[0007] According to one embodiment of the present disclosure, a wearable electronic device includes a first housing including a first body and a first fastening portion extending from the first body, a second housing including a second body and a second fastening portion extending from the second body and connectable with the first fastening portion, a first speaker disposed on the first body and connected to a first speaker hole formed in the first body, a second speaker disposed on the second body and connected to a second speaker hole formed in the second body, a 1-1 microphone disposed on the first body and adjacent to the first speaker, a 1-2 microphone disposed on the first fastening portion, a 2-1 microphone disposed on the second body and adjacent to the second speaker, and a 2-2 microphone disposed on the second fastening portion, wherein an end of the first fastening portion can be connected to an end of the second fastening portion.

[0008] According to one embodiment of the present disclosure, a wearable electronic device includes a plurality of wireless earphones that are connectable to each other and a detection sensor disposed on one of the plurality of wireless earphones to detect proximity of another one of the plurality of wireless earphones, wherein each of the plurality of wireless earphones may include a microphone, a speaker, a wearing detection sensor, a memory, and a processor operatively connected to the microphone, the speaker, the wearing detection sensor, and the memory. The memory may include instructions that, when executed, cause the processor to receive a signal generated by the detection sensor when the plurality of wireless earphones are connected, receive a signal generated by the wearing detection sensor of a wireless earphone worn on a user's body based on whether one of the plurality of wireless earphones is worn on a user's body, activate the speaker of a wireless earphone among the plurality of wireless earphones in which a signal is generated from the wearing detection sensor, and activate at least one of the microphones of a wireless earphone among the plurality of wireless earphones in which a signal is not generated from the wearing detection sensor.

[0009] According to various embodiments disclosed herein, a plurality of wireless earphones may be coupled. For example, the plurality of wireless earphones may each include a body worn on a user's ear and a connecting portion extending from the body toward the user's mouth. The plurality of wireless earphones may be coupled by connecting the ends of the connecting portions. Accordingly, when one of the plurality of wireless earphones is worn on one ear of the user while the plurality of wireless earphones are coupled, the other wireless earphone may be positioned around the user's mouth. Accordingly, the user may receive sound output from the speaker through the wireless earphone worn on one ear while the plurality of wireless earphones are coupled. A microphone positioned on the other wireless earphone, which is not worn on the user's ear, may be positioned around the user's mouth to receive the user's voice. Therefore, when the plurality of wireless earphones are coupled and worn on the user's ear, the distance between the microphone positioned on the wireless earphone not worn on the user's ear and the user's mouth may be reduced, thereby improving call quality.

As another example, the first wireless earphone (301) can first be connected to the external electronic device, and the second wireless earphone (302) can receive communication information for a communication connection with the external electronic device from the first wireless earphone (301) and establish a communication connection with the external electronic device.

[0081] According to one embodiment, as illustrated in FIGS. 6A and 6B, the first wireless earphone (301) and the second wireless earphone (302) may be coupled. The first wireless earphone (301) and the second wireless earphone (302) may include a structure that is capable of being fastened to each other. In one embodiment, referring to FIG. 5, the first wireless earphone (301) may include a fastening groove (332) formed at an end (e.g., a tip) (3121) of the first fastening portion (312). The second wireless earphone (302) may include a protrusion (331) formed at an end (e.g., a tip) (3221) of the second fastening portion (322) and inserted into the fastening groove (332).

In this case, the fastening groove (332) may be formed at the end (3221) of the second fastening portion (322) of the second wireless earphone (302). For convenience of explanation, the following description will be given on the assumption that the fastening groove (332) is formed at the first wireless earphone (301) and the protrusion (331) is formed at the second wireless earphone (302).

[0082] According to one embodiment, as illustrated in FIGS. 5, 6A, and 6B, magnet members (M1, M2) may be respectively disposed at the end (3121) of the first fastening portion (312) of the first wireless earphone (301) and the end (3221) of the second fastening portion (322) of the second wireless earphone (302). In one embodiment, the first magnet member (M1) may be disposed at the lowermost end of the first fastening portion (312) of the first wireless earphone (301). The second magnet member (M2) may be disposed at the lowermost end of the second fastening portion (322) of the second wireless earphone (302). In one embodiment, the first magnet member (M1) disposed at the end of the first fastening portion (312) and the second magnet member (M2) disposed at the end of the second fastening portion (322) may have different poles facing each other when the ends of the first fastening portion (312) and the second fastening portion (322) face each other.

For example, the pole of the first magnet member (M1) facing the second magnet member (M2) may be the N pole, and the pole of the second magnet member (M2) facing the first magnet member (M1) may be the S pole. Conversely, the first magnetic member (M1) may have a south pole facing the second magnetic member (M2), and the second magnetic member (M2) may have a north pole facing the first magnetic member (M1). Accordingly, the first wireless earphone (301) and the second wireless earphone (302) may maintain a coupled state through a magnetic force acting between the first magnetic member (M1) and the second magnetic member (M2) in a coupled state.

[0083] According to one embodiment, as illustrated in FIGS. 5, 6A, and 6B, the detection sensor (400) may be disposed on either the first fastening portion (312) or the second fastening portion (322).

Additionally, the detection sensor (400) may be disposed parallel to the second magnetic member (M2) at the end (3221) of the second fastening portion (322). In one embodiment, the detection sensor (400) may be disposed on either the first fastening portion (312) or the second fastening portion (322) to generate a signal based on the proximity of the other one of the first fastening portion (312) and the second fastening portion (322). For example, the detection sensor (400) can detect the proximity of the second fastening portion (322) and generate a signal when the first fastening portion (312) and the second fastening portion (322) are connected while being placed at the end of the first fastening portion (312).

[0084] In one embodiment, the detection sensor (400) may be a Hall sensor. The detection sensor (400) may detect a magnetic field formed by a second magnetic member (M2) disposed on the second fastening portion (322) when the first fastening portion (312) and the second fastening portion (322) are coupled while being disposed on the end (3121) of the first fastening portion (312), thereby generating a signal. The signal generated by the detection sensor (400) may be transmitted to the first processor (411) and / or the second processor (412). The first processor (411) and / or the second processor (412) may determine that the first wireless earphone (301) and the second wireless earphone (302) are coupled based on the signal generated by the detection sensor (400).

[0085] In the above description, the detection sensor (400) is described as a Hall sensor, but may not be limited thereto. In one embodiment, the detection sensor (400) may be a proximity sensor (e.g., an inductive proximity sensor, a capacitive proximity sensor, an optical proximity sensor, and / or an ultrasonic proximity sensor).

[0091] FIG. 9 is a schematic diagram of a state in which one wireless earphone is worn on a user's body while a plurality of wireless earphones are combined, according to one embodiment of the present disclosure. FIG. 10 is a diagram illustrating control of a plurality of wireless earphones, according to one embodiment of the present disclosure.

[0092] According to one embodiment, as illustrated in FIG. 9, the user may wear the first wireless earphone (301) or the second wireless earphone (302) on either ear while the first wireless earphone (301) and the second wireless earphone (302) are coupled. In one embodiment, when the first wireless earphone (301) is worn on the user's ear, the second body (321) of the second wireless earphone (302) may be adjacent to the user's mouth. In this case, the second-first microphone (441) arranged on the second body (321) may be adjacent to the user's mouth. Conversely, when the second wireless earphone (302) is worn on the user's ear, the first body (311) of the first wireless earphone (301) may be adjacent to the user's mouth. In this case, the first-first microphone (431) arranged on the first body (311) may be adjacent to the user's mouth. Accordingly, as the distance between the microphone of the wireless earphone (301, 302) (e.g., the 1-1 microphone (431) or the 2-1 microphone (441)) and the user's mouth becomes closer, the transmission volume can be increased and the call quality can be improved.

[0093] According to one embodiment, FIG. 10 is a diagram illustrating a series of processes in which a first processor (411) of a first wireless earphone (301) and / or a second processor (412) of a second wireless earphone (302) controls a speaker and a microphone of the wireless earphone.

[0094] In one embodiment, one of the first processor (411) of the first wireless earphone (301) and the second processor (412) of the second wireless earphone (302) may be a main processor and the other may be a sub-processor. The main processor and the sub-processor may communicate with each other based on wireless communication (e.g., Bluetooth communication or BLE (Bluetooth low energy) communication). The main processor may receive signals generated from electronic components of the wireless earphones (301, 302) in which the main processor is disposed and the wireless earphones (301, 302) in which the sub-processor is disposed, and control the wireless earphones (301, 302). In one embodiment, the first processor (411) and the second processor (412) may independently control the first wireless earphone (301) and the second wireless earphone (302), respectively.

[0095] In one embodiment, referring to FIG. 10, the first processor (411) and / or the second processor (412) can determine whether the first wireless earphone (301) and the second wireless earphone (302) are worn on the user's left ear and right ear, respectively. For example, the first processor (411) and / or the second processor (412) can determine whether the first wireless earphone (301) is worn on the user's ear by receiving a signal generated from the first wearing detection sensor (451) when the first wireless earphone (301) is worn on the user's ear. In addition, the second processor (412) and / or the second processor (412) can determine whether the second wireless earphone (302) is worn on the user's ear by receiving a signal generated from the second wearing detection sensor (452) when the second wireless earphone (302) is worn on the user's ear. In one embodiment, the first processor (411) and / or the second processor (412) can detect a state in which the first wireless earphone (301) and the second wireless earphone (302) are worn on the user's ears and activate the first speaker (421) and the first microphone of the first wireless earphone (301) and the second speaker (422) and the second microphone of the second wireless earphone (302) (510, 520).

[0096] In one embodiment, referring to FIG. 10, the first processor (411) and / or the second processor (412) may detect a state in which one of the first wireless earphone (301) and the second wireless earphone (302) is worn on the user's ear when the first wireless earphone (301) and the second wireless earphone (302) are coupled (530).

For example, the detection sensor (400) may be disposed at one of the end portion (3121) of the first fastening portion (312) and the end portion (3221) of the second fastening portion (322) to detect proximity of the other and generate a signal. In one embodiment, the first processor (411) and / or the second processor (412) may determine that the first wireless earphone (301) and the second wireless earphone (302) are in a coupled state upon receiving a signal generated from the detection sensor (400). In one embodiment, the first processor (411) and / or the second processor (412) can check whether one of the first wireless earphone (301) and the second wireless earphone (302) is worn on the user's ear when the first wireless earphone (301) and the second wireless earphone (302) are coupled to each other, and control the first speaker (421) and the first microphone (e.g., the 1-1 microphone (431) and / or the 1-2 microphone (432)) of the first wireless earphone (301), and control the second speaker (422) and the second microphone (e.g., the 2-1 microphone (441) and / or the 2-2 microphone (442)) of the second wireless earphone (302).For example, the first processor (411) and / or the second processor (412) may determine that the first wireless earphone (301) is worn on the user's ear by receiving a signal generated from the first wearing detection sensor (451) in a state where the first wireless earphone (301) and the second wireless earphone (302) are coupled (540). Alternatively, the first processor (411) and / or the second processor (412) may determine that the second wireless earphone (302) is worn on the user's ear by receiving a signal generated from the second wearing detection sensor (452) in a state where the first wireless earphone (301) and the second wireless earphone (302) are coupled.
