Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As used in embodiments herein, "electronic device" includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). Communication terminals arranged to communicate over a wireless interface may be referred to as "wireless communication terminals", "wireless terminals", and/or "mobile terminals". Examples of electronic devices include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver.

The current electronic devices integrate more and more functions, including photographing, video chatting, fingerprint identification, and the like. Although the functions of electronic devices are continuously updated, the performance is continuously improved, and the appearance is more and more exquisite, the call is always the most basic and important function. Current electronic devices are typically provided with a sound outlet hole corresponding to a receiver on the front side of the housing (e.g., on a display screen or a front housing) to allow a user to conveniently place an ear close to the sound outlet hole to answer a call.

When the user answers the phone in a normal posture, the ear of the user cannot completely cover the sound outlet hole, so that the sound emitted by the sound outlet hole is diffused to the outside of the ear of the user. When the external environment is quite quiet, the sound from the sound outlet hole can be easily heard by other people, and privacy disclosure is further caused. In view of the above, the present inventors have intensively studied to find a sound outlet hole scheme with better privacy, and the research of the present inventors includes but is not limited to the following: the sound leakage degree improving effect of the equivalent sound outlet section of the sound outlet hole, the sound leakage degree improving effect of the arrangement position of the sound outlet hole on the electronic equipment, the sound leakage degree improving effect of the relative position of the sound outlet hole and the receiver, the sound leakage degree improving effect of factors such as the specific structure of the sound outlet hole, the opening orientation and the like. After a large number of repeated researches, the inventor obtains a design idea: the loudness of sound outside the human ear communication range is reduced, so that sound from the sound outlet hole cannot be heard in other areas, or the distortion of sound outside the human ear communication range is increased, so that people in other areas cannot hear the sound from the sound outlet hole, and the purpose of protecting the privacy of a user can be achieved.

Under the guidance of the design idea, the inventor proposes a scheme of the electronic device of the application, wherein the electronic device comprises a shell, a receiver and a display screen. The casing has the inner chamber, and the receiver sets up in the inner chamber, and the inner chamber is including being located the preceding sound chamber and the back sound chamber of the relative both sides of receiver respectively. The display screen cover is arranged on the shell, and the edge of the display screen is connected with the shell; a sound outlet is arranged between the edge of the display screen and the shell and is communicated with the front sound cavity. The shell is provided with an inverter hole which is communicated with the rear sound cavity. Therefore, the sound waves transmitted by the rear sound cavity and the phase reversal hole and the sound waves transmitted by the sound outlet can be mutually offset, so that the loudness of the sound transmitted by the telephone receiver outside the auricle range of the user is reduced, the sound of the telephone receiver is prevented from being heard by other people around the user, and the voice privacy of the user using the electronic equipment is improved. The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

Referring to fig. 1, an electronic device 100 is provided in the present embodiment, and the electronic device 100 may be, but is not limited to, an electronic device such as a mobile phone, a tablet computer, and a smart watch. The electronic device 100 of the present embodiment is described by taking a mobile phone as an example. The electronic device 100 includes a housing 10, a display 30 disposed on the housing 10, and a receiver 50 disposed in the housing 10.

Referring to fig. 2, in the embodiment of the present application, the housing 10 is used for installing the display screen 30 and for accommodating electronic components of the electronic device 100, and the specific structural form of the housing 10 is not limited. Housing 10 has an interior 1010, and receiver 50 is disposed in interior 1010. Based on the receiver 50, the internal cavity 1010 of the housing 10 is substantially divided into a front sound cavity 1011 and a rear sound cavity 1013, in other words, the internal cavity 1010 of the housing 10 includes the front sound cavity 1011 and the rear sound cavity 1013 on opposite sides of the receiver 50. The display screen 30 is covered on the housing 10, and the edge of the display screen 30 is connected with the housing 10. A sound outlet 301 is arranged between the edge of the display screen 30 and the casing 10, and the sound outlet 301 is communicated with the front sound cavity 1011. The casing 10 is provided with an inverter hole 11, and the inverter hole 11 communicates with the rear sound chamber s 1013.

In the above-mentioned electronic device 100, the receiver 50 is disposed in the inner cavity 1010 of the electronic device 100, the sound outlet 301 is disposed between the edge of the display screen 30 and the housing 10, and the position of the sound outlet 301 does not need to occupy the installation space or the display space of the display screen 30, which is beneficial to vacating more installation space for the display panel of the display screen 30, so that the electronic device 100 has a higher screen occupation ratio on the premise of no change in the external dimension, and is beneficial to realizing the full-screen display of the electronic device 100. Further, in the embodiment of the present application, the casing 10 is further provided with an inverter hole 11 communicated with the rear sound cavity 1013, and the sound wave transmitted through the rear sound cavity and the inverter hole 11 is used for canceling the sound wave transmitted through the sound outlet 301, so that the loudness of the sound transmitted by the receiver 50 outside the pinna range of the user is reduced, the sound of the receiver 50 is prevented from being heard by other people around the user, and the voice privacy of the user using the electronic device 100 is improved.

Specifically, receiver 50 converts an audio electric signal into an audio analog signal, so that sound can be transmitted through sound outlet 301. It should be understood that "receiver" in this application should be understood in a general sense as an earpiece, i.e. the above-mentioned receiver should be understood as: an electroacoustic device for converting an audio electric signal into a sound signal without sound leakage (or a 3.2 type high/low leakage loop according to ITU standard) to realize audio (voice, music, etc.) reproduction. Receiver 50 of the present embodiment may be a moving coil receiver, which radiates sound signals by means of diaphragm vibration pushing air to transmit sound, i.e. receiver 50 radiates sound signals to its front and back simultaneously during operation.

In this embodiment, the front sound signal is referred to as a first sound signal a which enters the human ear through the front cavity 1011 and the sound outlet 301, and the back sound signal is referred to as a second sound signal B which propagates outward through the back cavity 1013 and the inverter hole 11. Based on the characteristics of the receiver 50, the phases of the first sound signal a and the second sound signal B are opposite, the amplitude of the second sound signal B is approximately smaller than or equal to the vibration amplitude of the first sound signal a, when the first sound signal a propagates to the region X outside the human ear, the second sound signal B can propagate to the region X substantially simultaneously, and the first sound signal a and the second sound signal B interfere with each other and are superimposed in the region X to form a third sound signal C. Since the phases of the first sound signal a and the second sound signal B are opposite, and the peak values of the two sound signals are weakened or even approximately cancelled by each other, the amplitude of the third sound signal C is very weak or substantially disappears, the intelligibility of the third sound signal C is reduced, and thus the intelligibility of the third sound signal C by other users in the area X is reduced, so that the sound signal transmitted to the area X by the electronic device 100 is not substantially heard by human ears in the area X. It should be understood that "area X" in this application is only an exemplary description, and does not limit the scope of this application, and the area around the user may be understood as area X when the user listens to sound using receiver 50 of electronic device 100, for example, area X may be an area outside the normal social range of the user (e.g., an area outside of 30 centimeters, 40 centimeters, 50 centimeters, etc. around the user). By using the electronic device 100 provided in the embodiment of the present application, the loudness of the sound emitted by the receiver 50 outside the pinna range of the user can be reduced (at this time, the region outside the pinna range of the user can be considered as "region X"), so that other people around the user are prevented from hearing the sound of the receiver 50, and the voice privacy of the user using the electronic device 100 is improved.

In the present embodiment, the display screen 30 may include a display panel, and may also include a circuit or the like for performing a touch operation on the display panel in response thereto. The Display panel may be a Liquid Crystal Display (LCD) panel, or may be an Active-matrix organic light-emitting diode (AMOLED) Display panel. The AMOLED display screen is a self-luminous display screen, and a backlight module (BLM) is not required. Therefore, when the substrate in the AMOLED display screen is made of a flexible resin material, such as Polyethylene Terephthalate (PET), the AMOLED display screen can have a bendable characteristic. In other embodiments, the display 30 may also be an Organic Light-Emitting Diode (OLED) display panel.

Referring to fig. 3, in the present embodiment, the display screen 30 includes a flat display portion 32 and a curved display portion 34. The curved display unit 34 is connected to at least one edge of the flat display unit 32, and is curved with respect to the flat display unit 32, so that the display screen 30 has a curved edge, and thus the smoothness of the structure of the electronic apparatus 200 can be improved. In the present embodiment, the curved surface display portion 34 may be connected to one edge, two edges, or more than two edges of the flat surface display portion 32, and is not limited to the description, for example, in the present embodiment, the flat surface display portion 32 is substantially rectangular, and has four edges, and the curved surface display portion 34 may be connected to one or more of the four edges. The following embodiment will be described by taking an example in which the curved display portion 34 is connected to one edge.

Specifically in the embodiment of fig. 3, the curved display portion 34 is connected to the top edge of the planar display portion 32. It should be noted that, in the embodiments of the present application, the type of the electronic device is not limited, and a more common placement manner of the electronic device during use is taken as a reference placement manner, a side facing a user is a "front side" or a "front side", a side facing away from the user is a "back side", a "top" refers to a portion close to an upper edge of the electronic device, and a "bottom" refers to a portion close to a lower edge of the electronic device. It should be understood that the names of the planar display portion and the curved display portion are set for convenience of description only, and are not meant to be a structural limitation of the display screen 30, and in an actual application scenario, the planar display portion and the curved display portion may not have obvious boundaries.

Curved surface display portion 34 meets with casing 10, sound outlet 301 is located between curved surface display portion 34 and casing 10, make sound outlet 301 export towards the oblique top of electronic equipment 100 (can understand to deviate from in the dead ahead or deviate from in the dead ahead), the auricle that is favorable to pressing close to the user also can avoid the skew to leak the sound with the conduction sound signal, when taking into account the convenience of use, avoid occupying the frontal display area of display screen 30, be favorable to improving the screen of electronic equipment 100 and account for the ratio. Further, a notch 341 is formed on a side of the curved display part 34 away from the flat display part 32, and the notch 341 is used for cooperating with the casing 10 to form the sound outlet 301. When the display 30 is assembled to the housing 10, the edge portion of the curved display portion 34 except the notch 341 is in contact with the housing 10, the edge portion of the notch 341 is spaced from the housing 10, and the sound outlet 301 is formed at the spaced position. In the present embodiment, the sound outlet 301 formed by the notch 341 is substantially slit-shaped, so that the sense of existence of the structure can be weakened, which is advantageous for ensuring the overall and consistent appearance of the electronic apparatus 100. In other embodiments, the shape of the sound outlet 301 may be a single hole or a plurality of holes, and the shape of the hole may be a circular hole, a square hole, or the like, which is not limited in this embodiment.

In some embodiments, the material of the frame part 121 may include, but is not limited to, any one or a combination of metals, plastics, resins, and rubbers. It should be understood that the bezel of the electronic device 100 refers to a side portion of the electronic device 100 in the thickness direction, and the bezel and the rear case (e.g., the rear case 14) and the front side surface (e.g., the display 30) of the electronic device 100 together form the appearance of the electronic device 100. The bezel of the electronic device 100 may be an integral structure with the front surface, an integral structure with the rear housing of the electronic device 100, or a separate bezel, and the specific structure thereof is not limited herein. In the embodiment shown in fig. 4, the frame portion 121 is assembled with the rear housing 14 and the display screen 30.

Referring to fig. 1 again, in the present embodiment, the frame portion 121 includes two first frames 124 and two second frames 125. In the present embodiment, the two first frames 124 are substantially parallel to each other, and the two second frames 125 are substantially parallel to each other. Two ends of each second frame 125 are respectively connected to two first frames 124, so that the frame portion 121 is substantially rectangular. In the embodiment shown in the figures, the first frame 124 is shorter than the second frame 125, such that the two first frames 124 respectively serve as the top frame and the bottom frame of the electronic device 100, and the two second frames 125 respectively serve as the left frame and the right frame of the electronic device 100. The left side frame mentioned above should be understood as a frame that the left hand of the user approaches when the user uses the electronic device 100 and the display screen 30 is in a vertical screen state and faces the front of the user; similarly, the "right side frame" should be understood as a frame that the right hand of the user approaches when the user uses the electronic device 100 and the display screen 30 faces the front of the user in a vertical screen state. It should be understood that the terms "first" and "second" in this specification are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

In the present embodiment, the sound outlet 301 is formed between the first frame 124 and the curved display portion 34 to allow the sound of the receiver 50 in the electronic device 100 to be transmitted from the top of the electronic device 100, which is more suitable for the usage habit of the user, so as to allow the user to conveniently move the electronic device 100 to the ear to listen to the audio without readjusting the holding posture. In other embodiments, the position where the sound outlet 301 is provided is not limited. For example, the sound outlet 301 may be disposed adjacent to any suitable location on the first bezel 124, or may be disposed between the second bezel 125 and the display screen 30. Further, in some embodiments, a dust screen or a waterproof sound-transmitting film is disposed in the sound outlet 301, and the dust screen or the waterproof sound-transmitting film is used to prevent particles such as dust and liquid from entering the interior of the electronic device 100 to damage the receiver 50, so as to further ensure the sound output reliability of the receiver 50 and have an effect of beautifying the appearance.

Referring to fig. 4, in the present embodiment, the middle frame plate 123 is used for mounting a printed circuit board, and the middle frame plate 123 is embedded in the side frame portion 121, so that the side frame portion 121 is disposed around the middle frame plate 123. When the middle frame plate 123 is installed in the frame portion 121, the middle frame plate 123 is located between the display screen 30 and the rear housing 14. In the present embodiment, the middle frame plate 123 and the frame part 121 are integrally formed, and both can be made of the same material through injection molding, die casting, stamping, or the like. In other embodiments, the middle frame plate 123 and the side frame 121 may be made of different materials, and they may be assembled and formed by a machine.

The bezel 123 includes a first surface 1231 and a second surface 1233 facing away from each other, the first surface 1231 facing the rear case 14, and the second surface 123 facing the display screen 30. First surface 1231 is used to mount receiver 50. Furthermore, the middle frame 12 is provided with a sound guiding channel 1234, the sound guiding channel 1234 penetrates through the middle frame plate 123 and the frame part 121, and communicates the sound outlet 301 with the front sound cavity 1011 of the receiver 50, so as to allow the sound signal of the receiver 50 to be transmitted out through the sound guiding channel 1234 and the sound outlet 301. In other embodiments, the sound guiding channel 1234 may extend through only the middle bezel 123, such that the display 30 is connected to the edge of the bezel 121 to form the sound outlet 301, and the sound guiding channel 1234 may communicate with the sound outlet 301 by using the space of the inner cavity 1010.

The receiver 50 is disposed on a side of the middle frame plate 123 facing the rear housing 14, and a diaphragm side of the receiver 50 faces the sound guide channel 1234. Further, in the present embodiment, in order to fix the receiver 50 and make the installation structure thereof compact, the middle frame plate 123 has an installation groove 1235 formed on the first surface 1231, and the receiver 50 is fixed in the installation groove 1235. The sound guiding channel 1234 penetrates the bottom of the mounting groove 1235 to form a certain space on one side of the diaphragm of the receiver 50 as a front sound cavity 1011, so as to ensure that the receiver 50 has a larger front sound cavity and better sound quality. When the receiver 50 is disposed in the mounting groove 1235, a surface of a side of the receiver 50 facing away from the diaphragm is recessed with respect to the first surface 1231, that is, the receiver 50 is substantially completely accommodated in the mounting groove 1235, and a certain vertical distance exists between the side of the receiver 50 facing away from the diaphragm and the first surface 1231. The vertical distance ensures that the mounting groove 1235 still has a spare space as the back cavity 1013 of the receiver 50 after accommodating the receiver 50, so that the receiver 50 has better low-frequency performance. Further, the electronic device 100 further includes a first sealing member 52, and the first sealing member 52 is disposed between the bottom wall of the mounting groove 1235 and the receiver 50. In this embodiment, the first sealing member 52 is a sealing ring, which substantially surrounds the opening of the sound guiding channel 1234 penetrating through the bottom wall of the mounting groove 1235 (i.e. the periphery of the front sound cavity 1011), so as to achieve the isolation between the front sound cavity 1011 and the rear sound cavity 1013, thereby preventing the sound signals at the front and rear sides of the receiver 50 from mixing, and ensuring that the receiver 50 has good sound quality.

In this embodiment, in order to effectively accommodate the receiver 50, the mounting groove 1235 may be designed in a stepped groove structure. Specifically, the mounting groove 1235 of the middle frame plate 123 includes at least a first groove 1236 and a second groove 1237 that communicate with each other, the first groove 1236 is disposed between the second groove 1237 and the sound guide channel 1234, a bottom wall of the first groove 1236 is used for carrying the first seal 52 and the receiver 50, and is penetrated by the sound guide channel 1234, and the second groove 1237 penetrates the first surface 1231. The cross-sectional area of first groove 1236 is smaller than the cross-sectional area of second groove 1237 with the plane substantially parallel to middle frame plate 123, so that mounting groove 1235 is substantially stepped groove-shaped, and positioning and mounting of receiver 50 are facilitated. In the present embodiment, the step 1238 is formed between the first groove 1236 and the second groove 1237, and the direction of the step 1238 matches the direction of the first surface 1231. The receiver 50 is substantially completely accommodated in the first groove 1236, and the surface of the receiver 50 facing away from the diaphragm thereof is recessed with respect to the step 1238, so that the back cavity 1013 is substantially formed in the first groove 1236.

Further, in order to ensure the tightness of the rear sound chamber 1013, the electronic device 100 further includes a second sealing 54 for sealing the rear sound chamber 1013, the second sealing 54 is disposed between the middle frame plate 123 and the rear case 14, and is used for sealing the rear sound chamber 1013 except for a region communicating with the inverter hole 11, so as to ensure that the sound wave in the rear sound chamber 1013 can vibrate and leak to the outside substantially exclusively via the inverter hole 11, thereby ensuring that the amplitude and phase of the second sound signal B have high fidelity, and thus effectively canceling the first sound signal B in the region X to achieve the effect of avoiding the leakage of the sound signal. Further, in the present embodiment, the second sealing member 54 may be made of an elastic material, for example, a bonding glue (such as double-sided tape, foam glue, etc.), foam, silicone, rubber, etc., to ensure a good sealing effect.

In the embodiment shown in fig. 4, the second sealing member 54 is substantially plate-shaped, and covers the mounting groove 1235 and substantially seals the circumference of the mounting groove 1235. The second packing 54 has a sound guide hole 541, and the sound guide hole 541 connects the back sound chamber 1013 and the inverter hole 11. Further, the second packing 54 is accommodated in the second groove 1237 and stacked on the step 1238, and the second packing 54 occupies a part of the space of the installation groove 1235, so as to reduce the volume of the back sound chamber 1013 to a certain extent, so as to ensure that the sound wave in the back sound chamber 1013 can vibrate and leak to the outside substantially exclusively via the inverter hole 11.

Further, in the present embodiment, the second sealing 54 may include a sealing portion 543 and a sound guide tube 545. The sealing portion 543 is substantially plate-shaped and is stacked on the stepped portion 1238. The sound guiding tube 543 is disposed on a side of the sealing portion 543 away from the step portion 1238, and an end of the sound guiding tube 545 away from the sealing portion 543 contacts the housing 12. Sound conduction port 541 of second packing 54 penetrates seal 543 and sound conduction pipe 545 to connect back chamber 1013 and inverter hole 11. In the present embodiment, the sound guide hole 541 and the inverter hole 11 are arranged substantially coaxially. In other embodiments, the axes of the sound guide hole 541 and the inverter hole 11 may be offset from each other, or the sound guide hole 541 is not limited to a straight hole, and may be a curved hole as long as it is ensured that it communicates the back cavity 1013 and the inverter hole 11.

The shape of the sound guide hole 541 is not limited, and may be a circular hole, a square hole, a triangular hole, a polygonal hole, a special-shaped hole, or the like. In this embodiment, the sound guide hole 541 may be a circular hole with a diameter in a range of 0.8-2 mm, for example, the diameter of the sound guide hole 541 may be 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.8mm, 2.0mm, or the like, or the diameter of the sound guide hole 541 may fall within a range defined by any two of the above values. When the sound guide hole 541 has a circular shape or a shape other than a circular shape, its size may be defined by its cross-sectional area.
