Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to an electronic device. Background Technology

[0002] Omnidirectional microphones are commonly used in electronic devices such as mobile phones, tablets, and laptops for sound pickup. Omnidirectional microphones maintain a consistent response to sound signals from all directions in space; when multiple omnidirectional microphones are arranged in an array, array algorithms amplify sound from specific directions within the space. However, when multiple omnidirectional microphones are arranged in an array, the spacing between the microphones is crucial, and due to limitations in array algorithms, the directional performance at different frequencies often varies significantly, leading to a decrease in overall directional performance. Furthermore, the poor frequency consistency of array algorithms across different frequencies results in varying gain effects on sound signals at different frequencies, producing a phenomenon known as sound coloration, which affects the sound quality of the picked-up sound, especially noticeable in complex acoustic environments. Summary of the Invention

[0003] This application provides an electronic device to solve the technical problem in the related art where the directional performance is reduced and the sound pickup effect is affected when multiple omnidirectional microphone arrays are arranged.

[0004] The technical solution is as follows:

[0005] This application provides an electronic device, which includes: a directional microphone and a body structure;

[0006] A directional microphone includes a housing, a substrate, and a diaphragm, the housing and substrate being connected to form a cavity, and the diaphragm being configured to divide the cavity into a first chamber and a second chamber;

[0007] The body structure has an inner cavity, in which a directional microphone is located. The outer surface of the body structure is provided with a first sound receiving hole and a second sound receiving hole. The first sound receiving hole is connected to the first cavity, and the second sound receiving hole is connected to the second cavity.

[0008] By adopting the above technical solution, a directional microphone is used to ensure directional performance and sound pickup effect in a specific direction. Furthermore, by connecting the two chambers of the directional microphone with the two sound holes on the body structure, the directional microphone is made compatible with the body structure, and the directional microphone is stacked inside the body structure.

[0009] In some implementations, the electronic device also includes a bracket and an electrical connector, wherein the electrical connector is a plate-like structure, the bracket is disposed in the inner cavity, and the electrical connector is disposed in the inner cavity;

[0010] The electrical connector is fixedly connected to the bracket, and the directional microphone is fixed to the electrical connector.

[0011] By adopting the above technical solution, brackets and electrical connectors are used to facilitate the installation of directional microphones inside electronic devices.

[0012] In some implementations, a first through hole is formed on the substrate;

[0013] The electrical connector has a second through hole, and the first through hole and the second through hole are coaxially arranged;

[0014] The first sound hole, the second through hole, the first through hole, and the first chamber are connected in sequence.

[0015] By adopting the above technical solution, a second through hole is opened on the electrical connector to facilitate the connection between the first chamber of the directional microphone and the outside of the electronic device.

[0017] The electrical connector has a fourth through hole, and the third through hole and the fourth through hole are coaxially arranged;

[0018] The second sound hole, the fourth through hole, the third through hole, and the second chamber are connected in sequence.

[0019] By adopting the above technical solution, after opening the third and fourth through holes on the electrical connector, the directional microphone can be stacked inside the body structure, which is conducive to the thinning of electronic devices. In addition, it allows the directional microphone to capture sound from a specific direction more accurately, which helps to filter out unwanted background noise and improve the sensitivity and signal-to-noise ratio of the directional microphone.

[0023] The second sound hole, the first plate through hole, the first flow cavity, the fourth through hole, the third through hole, and the second chamber are connected in sequence.

[0024] By adopting the above technical solution, the connection between the second chamber and the second sound hole is constructed in this way, which is beneficial for the directional microphone to be stacked inside the body structure, thereby facilitating the thinning of electronic devices.

[0025] In some implementations, a shell through-hole is provided on the outer shell;

[0026] The second sound hole, the shell through hole, and the second chamber are connected in sequence.

[0027] By adopting the above technical solution, a shell through hole is opened on the outer shell of the directional microphone to facilitate the connection between the second sound receiving hole and the second chamber, thereby adjusting the propagation path of the sound wave and the way the sound enters, thus enhancing the ability to pick up sound from a certain direction. This allows the directional microphone to more accurately capture sound from a specific direction, thereby helping to filter out unwanted background noise and improve the sensitivity and signal-to-noise ratio of the directional microphone.

[0028] In some implementations, the electronic device includes a first shield and a second shield, and the electrical connector is further provided with a first plate through hole and a second plate through hole;

[0031] The first sound hole, the second plate through hole, the second flow cavity, the first plate through hole, the first flow cavity, the second through hole, the first through hole, and the first chamber are connected in sequence.

[0032] By adopting the above technical solution, directional microphones can be stacked inside the body structure, which is beneficial for the thinning of electronic devices. In addition, it can also allow directional microphones to capture sound from a specific direction more accurately, which helps to filter out unwanted background noise and improve the sensitivity and signal-to-noise ratio of directional microphones.

[0036] By adopting the above technical solution, the design position of the first microphone hole is determined according to the actual use of the electronic device, which can ensure that the directional microphone can capture clear sound from a specific direction and avoid poor sound quality due to an undesirable audio source location. Furthermore, when the first microphone hole is placed in multiple different locations (such as on the bezel, back cover, and the connection between the display and the bezel), the audio reception range of the device can be optimized, improving sound quality.

[0037] In some implementations, at least one of the connection between the display and the bezel, the back cover, and the bezel is provided with a second microphone hole.

[0038] By adopting the above technical solution, the design position of the second microphone hole is determined according to the actual use of the electronic device. This ensures that the directional microphone can capture clear sound from a specific direction, avoiding poor sound quality due to an undesirable audio source location. Furthermore, placing the second microphone hole in multiple different locations (such as on the bezel, back cover, and at the connection between the display and the bezel) can optimize the device's audio reception range and improve sound quality.

[0041] By adopting the above technical solution, the directional microphone can be fixed in two positions on the electrical connector: one is facing the side of the display screen. This arrangement helps ensure that the directional microphone can accurately receive sound from the user or the front of the device, reducing interference from ambient noise. The other is facing away from the display screen. This arrangement is suitable for scenarios that require picking up sound from behind the device or the background, or for applications where the device simultaneously performs bidirectional sound acquisition (such as conference microphones, ambient sound pickup, etc.), thereby helping to expand the microphone's pickup range and making it suitable for a wider range of audio capture scenarios.

[0092] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0093] It should be understood that "multiple" as mentioned in this application refers to two or more. In the description of this application, unless otherwise stated, " / " indicates "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist, for example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, to facilitate a clear description of the technical solutions of this application, the terms "first," "second," etc., are used to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and that "first," "second," etc., do not necessarily imply differences.

[0094] In related technologies, omnidirectional microphones are commonly used for sound pickup in electronic devices such as mobile phones, tablets, and laptops. Omnidirectional microphones maintain a consistent response to sound signals from all directions in space; when multiple omnidirectional microphone arrays are arranged, array algorithms enhance sound from specific directions in space. However, in large conferences and presentations, it is often necessary to pick up sound from specific directions at a distance, while the pickup distance of multiple omnidirectional microphone arrays is relatively short. Furthermore, when multiple omnidirectional microphone arrays are arranged, the spacing between different microphones is required to be high, and due to the limitations of array algorithms, the directional effect at different frequencies often varies significantly, leading to a decrease in overall directional performance. Moreover, because the frequency consistency of array algorithms is poor at different frequencies, the gain effect on sound signals at different frequencies varies, producing the so-called sound coloration phenomenon, thus affecting the sound quality of the picked-up sound, especially in complex acoustic environments.

[0095] Therefore, this application provides an electronic device to solve the problems in the related technology; the electronic device provided in this application will be explained in detail below.

The wearable device can be a smartwatch, VR (Virtual Reality) wearable device, etc. Of course, the electronic device can also be other devices that need to pick up sound signals, such as acoustic cameras and XR (Extended Reality) related devices.

[0097] For ease of description, such as Figure 1 and Figure 2 As shown, the length direction of the electronic device can be defined as the AA direction, the width direction can be defined as the BB direction, and the thickness direction can be defined as the CC direction; the thickness direction, width direction, and length direction of the electronic device are all perpendicular to each other. For example, the electronic device in this embodiment is described using a mobile phone as an example.

[0098] Combination Figure 1 and Figure 2As shown, in some embodiments, the electronic device includes a body structure 100, which has an inner cavity 101. The body structure 100 includes a frame 103, a display screen 102, and a back cover 104.

The display screen 102 and the back cover 104 are respectively connected to the frame 103. For example, the inner cavity 101 formed by the display screen 102, the back cover 104, and the frame 103 can effectively protect the internal components of the electronic device, preventing external impacts, dust, moisture, and other factors from entering, thereby improving the durability and service life of the electronic device.

[0099] See Figure 2 As shown, in some embodiments, the electronic device further includes a lens trim 105 and a lens module (not shown), the lens module being mounted in the inner cavity 101.

[0101] In some embodiments, the directional microphone 200 is a MEMS microphone. MEMS microphones offer a compact, high-performance, low-power, interference-resistant, and durable audio acquisition solution, suitable for space-constrained applications and those requiring high-quality audio acquisition. Furthermore, the directionality, noise suppression, and environmental adaptability of MEMS microphones can significantly improve the audio processing performance of devices, optimizing the user's voice recognition, call, and recording experience.

[0102] See Figure 3As shown, in some embodiments, the directional microphone 200 includes a housing 201, a substrate 202, and a diaphragm 203.

The directional microphone 200 is located in the inner cavity 101. The outer surface of the body structure 100 is provided with a first sound-receiving hole 106 and a second sound-receiving hole 107. The first sound-receiving hole 106 is connected to the first chamber 204, and the second sound-receiving hole 107 is connected to the second chamber 205. By using a directional microphone 200, the electronic device can ensure directional performance and specific directional sound pickup. Furthermore, by connecting the two chambers of the directional microphone 200 to the two sound-receiving holes on the body structure 100, the directional microphone 200 is made compatible with the body structure 100, allowing the directional microphone 200 to be stacked inside the body structure 100, thereby facilitating the thinning of the electronic device. For example, the first chamber 204 can also be called the rear chamber, and the second chamber 205 can also be called the front chamber; the first sound receiving hole 106 is a through hole, and the second sound receiving hole 107 is a through hole.

[0103] See Figure 3 As shown in this embodiment, the electronic device further includes a bracket 108 and an electrical connector 109. The electrical connector 109 has a plate-like structure. The bracket 108 is disposed in the inner cavity 101, and the electrical connector 109 is disposed in the inner cavity 101. The electrical connector 109 is fixedly connected to the bracket 108, and the directional microphone 200 is fixed to the electrical connector 109. The bracket 108 and the electrical connector 109 are used to facilitate the installation of the directional microphone 200 inside the electronic device. For example, the frame 103 and the bracket 108 can be formed into an integral structure using an integral molding process, or the frame 103 can be made of metal, while the bracket 108 can be made of plastic, and the frame 103 and the bracket 108 can be formed into an integral structure using an insert injection molding process; the frame 103 and the bracket 108 can form a middle frame. The electrical connector 109 is a circuit board. Designing the electrical connector 109 as a circuit board can provide efficient electrical connection, signal transmission, and component integration, optimize space utilization, and simplify device design. The circuit board can be a rigid circuit board or a flexible circuit board; when the circuit board is a flexible circuit board, the electronic device also includes a supporting steel sheet, which is combined with the flexible circuit board to form a rigid structure. The display screen 102 and the bracket 108 can be bonded together, for example, by using adhesive backing to achieve the bonding connection between the two.

After forming the third through-hole 208 and the fourth through-hole 112 on the electrical connector 109, the directional microphone 200 can be stacked inside the body structure 100, which is beneficial for the thinning of electronic devices. In addition, it allows the directional microphone 200 to more accurately capture sound from a specific direction, thereby helping to filter out unwanted background noise and improve the sensitivity and signal-to-noise ratio of the directional microphone 200.

This connection between the second chamber 205 and the second microphone hole 107 facilitates the stacking of the directional microphone 200 inside the body structure 100, thereby contributing to the thinning of the electronic device. For example, the second microphone hole 107, the second sound channel 114, the first plate through hole 116, the first flow cavity 117, the fourth through hole 112, the third through hole 208, and the second chamber 205 are sequentially connected, thus enabling the second chamber 205 to communicate with the outside world of the electronic device. The first shielding cover 115 can be made of metal, such as stainless steel or aluminum alloy. The first microphone hole 106, the first sound channel 113, the second through hole 110, the first through hole 206, and the first chamber 204 are sequentially connected.

The second microphone hole 107 is located on the back cover 104. This ensures that the directional microphone 200 can capture clear sound from a specific direction, avoiding poor sound quality due to an undesirable audio source location.

[0116] See Figure 6As shown, in some embodiments, the first microphone hole 106 is disposed on the lens trim 105, and the axis of the first microphone hole 106 is parallel to the thickness direction of the electronic device. The second microphone hole 107 is located at the connection between the lens trim 105 and the rear cover 104. For example, since the lens trim 105 is fixed to the rear cover 104, the second microphone hole 107 is located between the side of the lens trim 105 facing the rear cover 104 and the outer surface of the rear cover 104. The orientation of the opening of the second microphone hole 107 on the outside of the electronic device is perpendicular to the thickness direction of the electronic device.

[0119] Figure 7 This is a schematic diagram of the structure of the fifth type of electronic device provided in the embodiments of this application. See also... Figure 7 As shown, in some other embodiments, Figure 7 The electronic devices shown are Figure 6 The main differences between the electronic devices shown are: Figure 7The first microphone hole 106 is also located at the connection between the lens trim 105 and the rear cover 104. For example, since the lens trim 105 is fixed to the rear cover 104, the first microphone hole 106 is located between the side of the lens trim 105 facing the rear cover 104 and the outer surface of the rear cover 104. The orientation of the opening of the first microphone hole 106 on the outside of the electronic device is perpendicular to the thickness direction of the electronic device. By designing the specific positions of the first microphone hole 106 as needed, it can be ensured that the directional microphone 200 can capture clear sound from a specific direction, avoiding poor sound quality due to an undesirable audio source location. It should be noted that in some other possible embodiments, the first microphone hole 106 can also be opened on the surface of the lens trim 105 parallel to the thickness direction of the electronic device, where the thickness direction of the lens trim 105 is parallel to the thickness direction of the electronic device.

Figure 8 As shown, in some embodiments, the outer casing 201 has a casing through hole 209, which communicates with the second chamber 205; the second sound receiving hole 107, the casing through hole 209, and the second chamber 205 are sequentially connected. By providing a casing through hole 209 on the outer casing 201 of the directional microphone 200 to facilitate communication between the second sound receiving hole 107 and the second chamber 205, the propagation path of the sound wave and the way the sound enters can be adjusted, thereby enhancing the ability to pick up sound from a certain direction. This allows the directional microphone 200 to more accurately capture sound from a specific direction, which helps to filter out unwanted background noise and improve the sensitivity and signal-to-noise ratio of the directional microphone 200.

[0122] See Figure 8As shown, in some embodiments, the directional microphone 200 is fixed to one side of the electrical connector 109, away from the display screen 102. This arrangement is suitable for scenarios requiring the pickup of sound from behind or in the background, or for applications where the device simultaneously performs bidirectional sound acquisition (such as conference microphones, ambient sound pickup, etc.), thereby helping to expand the microphone's pickup range and making it suitable for a wider range of audio capture scenarios.

The second chamber 209 and the second cavity 205 are sequentially connected; the accessory 119 can be a plate-like structure or a tubular structure, which facilitates the connection between the shell through hole 209 and the second microphone hole 107; for example, the second microphone hole 107 is disposed on the rear cover 104, so that in the thickness direction of the electronic device, the accessory 119 is located between the shell 201 and the rear cover 104; the first microphone hole 106 is located on the frame 103, for example, the first microphone hole 106 is located on the side of the frame 103 parallel to the thickness direction of the electronic device, which can ensure that the directional microphone 200 can capture clear sound from a specific direction.

[0124] See Figure 8 As shown, in some other embodiments, to ensure the airtight connection between the second through hole 110 and the first sound channel 113, a seal 118 is provided between the electrical connector 109 and the bracket 108; to ensure the airtight connection between the second sound channel 114 and the second sound receiving hole 107, a seal 118 is provided between the accessory 119 and the inner side of the rear cover 104, with the inner side of the rear cover 104 facing the inner cavity 101.

That is, a portion of the inner wall of the first sound channel 113 can be the side of the display screen 102 facing the inner cavity 101. The display screen 102 and the bracket 108 can be fixed by adhesive dispensing or by providing a silicone structure, foam structure, plastic structure 120, or rubber structure between the display screen 102 and the bracket 108 to ensure the sealing of this portion of the area, thereby achieving a lack of communication between the first sound channel 113 and the inner cavity 101.

[0143] See Figure 13 As shown, in some embodiments, a first microphone hole 106 is disposed on the lens trim 105, and the axis of the first microphone hole 106 is parallel to the thickness direction of the electronic device. A second microphone hole 107 is located at the connection between the lens trim 105 and the rear cover 104. For example, since the lens trim 105 is fixed to the rear cover 104, the second microphone hole 107 is located between the side of the lens trim 105 facing the rear cover 104 and the outer surface of the rear cover 104. The orientation of the opening of the second microphone hole 107 on the outside of the electronic device is perpendicular to the thickness direction of the electronic device. By designing the specific positions of the first microphone hole 106 and the second microphone hole 107 as needed, it can be ensured that the directional microphone 200 can capture clear sound from a specific direction, avoiding poor sound quality due to an undesirable audio source location.

Figure 14 As shown, in some other embodiments, Figure 14 The electronic devices shown are Figure 13 The main differences between the electronic devices shown are: Figure 14 The first microphone hole 106 is also located at the connection between the lens trim 105 and the rear cover 104. For example, since the lens trim 105 is fixed to the rear cover 104, the first microphone hole 106 is located between the side of the lens trim 105 facing the rear cover 104 and the outer surface of the rear cover 104. The orientation of the opening of the first microphone hole 106 on the outside of the electronic device is perpendicular to the thickness direction of the electronic device. By designing the specific positions of the first microphone hole 106 as needed, it can be ensured that the directional microphone 200 can capture clear sound from a specific direction, avoiding poor sound quality due to an undesirable audio source location. See also... Figure 14 As shown, the orientation of the first microphone hole 106, located on the exterior of the electronic device, is opposite to the orientation of the second microphone hole 107, also located on the exterior of the electronic device. It should be noted that in some other possible embodiments, when the first microphone hole 106 is located at the connection between the lens trim 105 and the rear cover 104, the second microphone hole 107 may be located on the lens trim 105, with its axial direction parallel to the thickness direction of the electronic device.

[0145] Figure 15 This is a schematic diagram of the thirteenth type of electronic device provided in the embodiments of this application. See also... Figure 15 As shown, in some other embodiments, a first through hole 206 is provided on the substrate 202, a second through hole 110 is provided on the electrical connector 109, a shell through hole 209 is provided on the outer shell 201, a second sound channel 114 is provided on the bracket 108, and the second sound hole 107, the second sound channel 114, the shell through hole 209 and the second chamber 205 are sequentially connected; the bracket 108 is also provided with a first sound channel 113, and the first sound hole 106, the first sound channel 113, the second through hole 110, the first through hole 206 and the first chamber 204 are sequentially connected.

[0146] See Figure 15 As shown, in some embodiments, to ensure the sealing of the connection between the housing through-hole 209 and the second sound channel 114, a seal 118 is provided between the housing 201 and the bracket 108 in the thickness direction of the electronic device; to ensure the sealing between the first sound channel 113 and the first microphone hole 106, a seal 118 is provided between the bracket 108 and the rear cover 104 or between the bracket 108 and the lens trim 105; to ensure the sealing between the first sound channel 113 and the second through-hole 110, a seal 118 is provided between the bracket 108 and the electrical connector 109. Thus, in the thickness direction of the electronic device, the directional microphone 200 is located between two different parts of the bracket 108, ensuring the stability of the directional microphone 200's position in the thickness direction of the electronic device. To ensure the sealing between the housing through-hole 209 and the second sound channel 114, a seal 118 is provided between the housing 201 and the bracket 108 in the thickness direction of the electronic device. The seal 118 can be made of sponge, foam, rubber, or silicone.

[0147] See Figure 15 As shown, in some other embodiments, the directional microphone 200 is located on the side of the electrical connector 109 facing the display screen 102. This arrangement helps ensure that the directional microphone 200 can accurately receive sound from the user or the front of the device, reducing interference from ambient noise.

[0148] See Figure 15 As shown, in some embodiments, a first sound-receiving hole 106 is provided on the lens decoration 105, a first sound-receiving hole 106 is provided at the connection between the lens decoration 105 and the back cover 104, a second sound-receiving hole 107 is provided at the connection between the display screen 102 and the frame 103, and a second sound-receiving hole 107 is provided on the frame 103. The electronic device also includes a first switch 126 and a second switch 127. The first switch 126 is used to control the connection between the two first sound-receiving holes 106 at different positions and the first chamber 204, and the second switch 127 is used to control the connection between the two second sound-receiving holes 107 at different positions and the second chamber 205. By cooperating with the first switch 126 and the second switch 127, the user can change the position of the connection between the first chamber 204 and the second chamber 205 and the outside world of the electronic device as needed, thereby optimizing the audio acquisition direction of the electronic device or reducing noise, so that the electronic device can adapt to different audio recording needs, such as ambient sound recording and directional recording. For example, the axial direction of a first microphone hole 106 located on the lens trim 105 is parallel to the thickness direction of the electronic device. Since the lens trim 105 is fixed to the rear cover 104, another first microphone hole 106 is located between the side of the lens trim 105 facing the rear cover 104 and the outer surface of the rear cover 104, and the orientation of the opening of this first microphone hole 106 on the outside of the electronic device is perpendicular to the thickness direction of the electronic device. A second microphone hole 107 is located at the connection between the display screen 102 and the bezel 103, ensuring that the directional microphone 200 can capture clear sound from a specific direction, avoiding poor sound quality due to an undesirable audio source location; for example, the display screen 102 is circumferentially connected to the bezel 103, and the second microphone hole 107 is located at a predetermined position circumferentially on the display screen 102. Another second microphone hole 107 is located on the side of the bezel 103 parallel to the thickness direction of the electronic device, ensuring that the directional microphone 200 can capture clear sound from a specific direction. For example, the second microphone 107 may be located at the top or bottom of the electronic device.

Since the direction of sound pickup enhancement is the direction of the line connecting the first microphone hole 106 and the second microphone hole 107, the first switch 126 controls the connection between the two first microphone holes 106 in different positions and the first chamber 204, and the second switch 127 controls the connection between the two second microphone holes 107 in different positions and the second chamber 205, thus enabling the switching of the microphone pickup direction.

[0150] See Figure 15 As shown, in some embodiments, the first switching switch 126 includes a first rotary motor 128 and a first baffle 129. The first baffle 129 is fixed to the output shaft of the first rotary motor 128 and is used to control the connection and disconnection between the two first microphone holes 106 at different positions and the first chamber 204. The second switching switch 127 includes a second rotary motor 130 and a second baffle 131. The second baffle 131 is fixed to the output shaft of the second rotary motor 130 and is used to control the connection and disconnection between the two second microphone holes 107 at different positions and the second chamber 205. The combination of the first rotary motor 128 and the first baffle 129, and the combination of the second rotary motor 130 and the second baffle 131, occupies less space and are suitable for use in devices requiring a compact structure.

The directional microphone 200 is located on the side of the electrical connector 109 facing the display screen 102. This arrangement helps ensure that the directional microphone 200 can accurately receive sound from the user or the front of the device, reducing interference from ambient noise.

In the thickness direction of the electronic device, the electrical connector 109 is clamped between two different parts of the bracket 108.

Since the lens trim 105 is fixed to the rear cover 104, another first microphone hole 106 is located between the side of the lens trim 105 facing the rear cover 104 and the outer surface of the rear cover 104, and the orientation of the opening of this first microphone hole 106 on the outside of the electronic device is perpendicular to the thickness direction of the electronic device.
