BACKGROUND

Field

The disclosure relates to an electronic device including an antenna and a microphone.

Description of Related Art

An electronic device may include antenna modules which support wireless communication services of various frequency bands, for example, 3G, 4G, or 5G services, etc. A processor (for example, a communication processor (CP)) of the electronic device may perform communication with a base station, and may determine a communication method to use in the electronic device. For example, a wireless communication circuit of the electronic device may perform communication with a base station using one or more of a 3G/4G communication method, or a 5G communication method.

The electronic device may include a microphone module. For example, the electronic device may include the microphone module to provide a communication function to a user. In addition, the electronic device may provide a voice recognition function using the microphone module.

The microphone module mounted in the electronic device may be easily broken by an external impact. Accordingly, the microphone module may include a microphone protection member to be protected from an external impact. For example, the microphone module may include a microphone housing. Durability of the electronic device may be reinforced by providing the microphone housing.

An electronic device may include a battery and/or a display the size of which increases so as to enhance usability of a user using the electronic device. However, the battery and/or the display mounted in the electronic device may have a trade-off relationship with other electronic components. For example, as the size of the battery and/or the display increases, an acoustic module (for example, a microphone module) may be disposed on an area that does not interfere with the battery and/or the display. For example, as areas of the battery and the display increase, the microphone module may be disposed on a periphery of the electronic device.

In addition, an antenna of the electronic device may be required to be disposed, spaced apart from an electronic component (for example, a microphone module) in order to guarantee radiation performance of the antenna. For example, the antenna may be disposed, spaced apart from the microphone module in order to avoid interference between a radio frequency (RF) signal and a microphone signal.

However, as a space for mounting the microphone module is reduced, the microphone and the antenna may be disposed adjacent to each other. For example, the microphone module may be disposed on a periphery of a housing of the electronic device in which the antenna is disposed. Accordingly, since the microphone and the antenna are disposed adjacent to each other, radiation performance of the antenna may be degraded due to interference by the microphone.

SUMMARY

Embodiments of the disclosure address the above-described problems by providing an electronic device including an antenna and a microphone.

According to various example embodiments of the disclosure, an electronic device may include: a housing forming an inner space of the electronic device; a printed circuit board (PCB) disposed in the inner space and including a ground; a microphone module including a microphone housing disposed at a point on the PCB adjacent to a side surface of the housing, the microphone housing being electrically connected with the ground; a conductive member comprising a conductive material disposed, spaced apart from a surface of the microphone housing by a specified distance or less, and overlapping at least part of the microphone housing with reference to a first direction in which a rear surface of the electronic device faces, the conductive member being coupled and electrically connected with the microphone housing; and a wireless communication circuit disposed on the PCB, wherein the wireless communication circuit is configured to transmit and/or receive a signal of a designated frequency band, based on an electrical path including the conductive member and the microphone housing, by feeding the conductive member.

According to various example embodiments of the disclosure, an electronic device may include: a housing configured forming an inner space of the electronic device, a part of the housing comprising a conductive member comprising a conductive material; a printed circuit board (PCB) disposed in the inner space and including a ground; a microphone module including a microphone housing disposed at a point on the PCB adjacent to a side surface of the housing, the microphone housing being electrically connected with the ground; and a wireless communication circuit disposed on the PCB, wherein the conductive member may be disposed, spaced apart from a surface of the microphone housing by a specified distance or less, and overlapping at least part of the microphone housing with reference to a second direction perpendicular to a first direction in which a rear surface of the electronic device faces, wherein the conductive member and the microphone housing may be coupled and electrically connected, and the wireless communication circuit may be configured to transmit and/or receive a signal of a designated frequency band, based on an electrical path including the conductive member and the microphone housing, by feeding the conductive member.

According to various example embodiments of the disclosure, the electronic device may not include an electrical connection member (for example, a c-clip). For example, the electronic device may transmit and/or receive a signal of a designated frequency band using the microphone housing as an electrical path, instead of an electrical connection member.

Since the electronic device does not include an electrical connection member, the electronic device may provide a space for mounting other electronic components (for example, an additional battery). By adding other electronic components, the electronic device may increase usability of a user.

In addition, according to various example embodiments, an antenna and the microphone housing may be coupled and electrically connected, such that the electronic device may provide substantially the same radiation performance as an antenna including the electrical connection member.

In addition, various effects that are directly or indirectly understood through the disclosure may be provided.

Regarding explanation of the drawings, the same or similar reference numerals may be used for the same or similar components.

According to an embodiment, the capacitor the impedance of which becomes relatively higher may be eventually opened and may operate as an open circuit.

According to an embodiment, a microphone signal (low frequency signal) may be distinguished by the capacitor540disposed on the third conductive path. However, an RF signal (for example, a high frequency signal) may not be distinguished by the capacitor540and may be transmitted along the third conductive path.

According to an embodiment, the RF signal may not be distinguished by the capacitor540, such that the wireless communication circuit510may transmit and/or receive a signal of a designated frequency band. Accordingly, the electronic device101may distinguish between a signal of a high frequency band and a signal of a low frequency band by the capacitor540.

According to an embodiment, the capacitor540may be disposed in the second portion502of the communication circuit500of the electronic device101, such that the electronic device101may use the microphone housing340as an electrical path. Accordingly, the electronic device101may transmit and/or receive a signal of a designated frequency band using an antenna including the microphone housing340.

Referring toFIG.5, the communication circuit500according to an embodiment may further include an impedance matching circuit. According to an embodiment, a third portion503of the communication circuit500may refer to the impedance matching circuit.

According to an embodiment, Table 1 shows reception sensitivity of an antenna in a first state in which the microphone331is not used, and a second state in which the capacitor540is used while the microphone331is used.

In addition, the second state may refer to a state in which the electronic device101transmits and/or receives a signal of a designated frequency band while using the capacitor540due to the use of the microphone331.

Referring to Table 1, when the capacitor540is used, the electronic device101using the microphone331may have substantially the same antenna reception sensitivity as that of the electronic device not using the microphone331.

According to an embodiment, referring to Table 1, an antenna in the first state of the first frequency band may have reception sensitivity of −89.1. According to an embodiment, an antenna in the second state may have reception sensitivity of −89.2.

According to an embodiment, an antenna in the first state of the second frequency band may have reception sensitivity of −94.1. In addition, an antenna in the second state may have reception sensitivity of −93.8.

Referring to antenna reception sensitivity of the first frequency band, the second frequency band, the third frequency band, the fourth frequency band, and the fifth frequency band, reception sensitivity in the second state may be substantially the same as reception sensitivity in the first state.

Accordingly, the electronic device101which transmits and/or receives a signal based on the electrical path including the microphone housing340and the capacitor540may guarantee substantially the same radiation performance as the electronic device101which transmits and receives a signal using an antenna including an electrical connection member (for example, a c-clip) without using the capacitor540.

According to an embodiment, the first inductor L1, the second inductor L2, the third inductor L3, and/or the fourth inductor L4may have different inductance values.

According to an embodiment, the third electrical path may have various electrical lengths due to the switching module550. In an example, when a first port551of the switching module550is connected with a second port552, the electrical length of the third electrical path may be shortened due to the first inductor L1having a low inductance value.

According to an embodiment, when the first port551of the switching module550is connected with a third port553, the electrical length of the third electrical path may be elongated due to the second inductor L2having an inductance value higher than the first inductor L1.

According to an embodiment, the first port551and the second port552of the switching module550may be electrically connected, such that the wireless communication circuit510may be grounded through the first inductor L1.

According to an embodiment, the first port551and the third port553of the switching module550may be electrically connected, such that the wireless communication circuit510may be grounded through the third inductor L3.

However, the lumped element included in the third portion503of the communication circuit500is not limited to the configuration illustrated inFIG.5. For example, the third portion503may include a combination of other additional lumped elements.

According to an embodiment, the wireless communication circuit510in the electronic device101may control the switching module550. For example, the wireless communication circuit510may control the switching module550to perform impedance matching in response to the designated frequency band.
