[0039] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0040] The embodiments of the present application provide a sound production module, as shown in Figure 1 The sound production module comprises:

[0041] The sound production module comprises a driving assembly 11 and a vibration transmission assembly 12.

[0042] The driving assembly 11 comprises a magnetic circuit module 111 and a voice coil 112. The magnetic circuit module 111 is configured to generate a first magnetic field. The voice coil 112 is configured to receive an audio signal, generate a second magnetic field based on the audio signal, and vibrate in a first direction under the interaction of the first magnetic field and the second magnetic field. The first direction is the connection direction of the magnetic circuit module 111 and the voice coil 112.

[0043] The vibration transmission assembly 12 is arranged on the voice coil 112 and configured to transmit the vibration of the voice coil 112 to an external contact component, so as to drive air vibration through the vibration of the external contact component, and output audio corresponding to the audio signal.

[0044] In some embodiments, as shown in Figure 1 The magnetic circuit module 111 can comprise a magnet support component 1111, a magnet 1112 and a magnet fixing component 1113. The magnet support component 1111 has a cavity with one open side for placing the magnet 1112. The magnet 1112 is configured to generate the first magnetic field. The magnet fixing component 1113 is configured to fix the magnet 1112 on the magnet support component 1111.

[0045] In specific implementation, the magnet support component 1111 can be a T-shaped iron. The T-shaped iron has a cavity with one open side, for example, a square cavity. The magnet 1112 can be a magnet. The magnet is placed in the cavity of the T-shaped iron and forms a gap with the side of the T-shaped iron. The magnet fixing component 1113 can be a pot core. The pot core covers the magnet, and the upper surface of the pot core is flush with the upper surface of the T-shaped iron and forms a gap with the side of the T-shaped iron.

[0046] In some embodiments, the voice coil 112 includes a voice coil former, enameled wire, reinforcing paper and lead wire. The voice coil former is a hollow structure. The enameled wire is wound on the voice coil former to form a coil structure. The coil structure is used to generate a second magnetic field after the voice coil 112 is introduced with an electric current. The lead wire is used to connect the voice coil 112 with the terminal to introduce the electric current into the voice coil 112. The conductor material of the lead wire is generally copper, pure copper, tin copper, cadmium copper, silver copper alloy, etc. The reinforcing paper is used to fix the lead wire and enhance the rigidity of the voice coil former, and is generally composed of kraft paper, lotus paper, non-woven fabric, aramid and some special composite materials.

[0047] In specific implementation, as shown in Figure 1 , the shape of the voice coil 112 can be set to be the same as the shape of the magnet supporting component 1111, for example, a square structure, so that the voice coil 112 can be placed in the gap between the magnet supporting component 1111 and the magnet 1112, so that the voice coil 112 surrounds the magnet 1112, and the upper surface of the voice coil 112 protrudes from the upper surface of the magnet supporting component 1111. After the voice coil 112 is introduced with an electric current, the voice coil 112 generates a second magnetic field. The first magnetic field and the second magnetic field interact with each other, so that the voice coil 112 vibrates along a first direction. The first direction is the connection direction of the magnetic circuit module 111 and the voice coil 112, that is, the vertical direction as shown in Figure 1 , that is, the voice coil 112 can vibrate up and down under the interaction of the first magnetic field and the second magnetic field. In this way, the voice coil can not only vibrate along the first direction, but also make the height of the sound production module smaller and reduce the size of the sound production module.

[0048] In some embodiments, in order to connect the voice coil 112 and the magnetic circuit module 111, as shown in Figure 1 , the voice coil 112 and the magnetic circuit module 111 can be connected through the support 13.

[0049] In specific implementation, the support 13 can be set to be a hollow structure with the same shape as the magnet supporting component 1111, for example, a hollow square structure, so that the support 13 can be placed in the gap between the voice coil 112 and the magnet supporting component 1111, so that the voice coil 112 and the magnetic circuit module 111 are connected. The upper surface of the support 13 protrudes from the upper surface of the voice coil 112.

[0050] In some embodiments, the vibration transmission assembly 12 is attached to the upper surface of the voice coil 112 and covers the hollow structure of the voice coil 112. On the one hand, the vibration transmission assembly 12 can prevent dust from entering the voice coil 112, and on the other hand, since the voice coil 112 is hollow inside, it is not good to be directly connected with the external contact component, so the vibration transmission assembly 12 can be connected with the external contact component to transmit the vibration of the voice coil 112 to the external contact component.

[0051] In some embodiments, as shown in Figure 2As shown, one surface of the external contact component 14 is connected with the vibration transmission assembly 12 of the sound production module, and the other surface is in contact with air. Thus, when the voice coil 112 vibrates based on the received audio signal, the vibration can be transmitted to the external contact component 14 through the vibration transmission assembly 12, so as to drive air to vibrate through the vibration of the external contact component 14, and output audio corresponding to the audio signal.

[0052] The sound production module provided by the embodiments of the present application can output audio corresponding to the audio signal without opening a hole on the front surface of the sound production module, so as to realize the sound production module without sound hole design, and perfectly meet the requirement of clean surface design of the electronic device. In addition, the sound production module drives the external contact component to vibrate, so as to drive air to vibrate and output audio corresponding to the audio signal, so that the sound production module can have infinite sound output rate, can respond to high-frequency audio signal, and can respond to high frequency up to 20 kHz, so as to better restore high-frequency sound and improve user experience.

[0053] In an optional embodiment, as shown in Figure 3 The vibration transmission assembly 12 includes:

[0054] The elastic component 121 is arranged on the voice coil 112, and is used to limit the amplitude of the voice coil 112 and keep the voice coil 112 vibrate along the first direction.

[0055] In the implementation, when the voice coil 112 receives the audio signal, that is, the current is passed through the voice coil 112, the voice coil 112 will vibrate in the first direction. In order to prevent the voice coil 112 from vibrating too large and producing lateral deflection when vibrating, the vibration transmission assembly 12 can be directly arranged as an elastic component 121. The elastic effect of the elastic component 121 can limit the amplitude of the voice coil 112 and keep the voice coil 112 vibrate along the first direction. In this way, the vibration transmission assembly 12 can be connected with the external contact component, limit the amplitude of the voice coil 112, and keep the voice coil 112 vibrate along the first direction.

[0056] In an optional embodiment, if the vibration intensity of the voice coil 112 is not very large, if the vibration transmission assembly 12 is directly arranged as an elastic component, the voice coil 112 can not drive the vibration transmission assembly 12 to vibrate, and the external contact component cannot be driven to vibrate. Therefore, the vibration transmission assembly 12 can be arranged as a combination of two components. The vibration transmission assembly 12, as shown in Figure 4As shown, the vibration transmission assembly not only includes the elastic component 121, but also includes a connecting component 122, which is arranged on the elastic component 121, the elastic component 121 has a first through hole, the connecting component 122 covers the first through hole of the elastic component 121, and the connecting component 122 is used to be connected with an external contact component to transmit the vibration of the voice coil to the external contact component.

[0057] In particular implementation, the elastic component 121 is attached to the upper surface of the voice coil 112, and the first through hole of the elastic component 121 is communicated with the through hole of the voice coil 112. The elastic component 121 can be a spring sheet in particular.

[0058] The connecting component 122 is attached to the elastic component 121 and covers the through hole of the elastic component 121. On the one hand, it can prevent dust from entering the voice coil 112, and on the other hand, since the elastic component 121 has a through hole and is inconvenient to be connected with the external contact component, the connecting component 122 can also play a role of being connected with the external contact component. The connecting component 122 can be a dust cover in particular.

[0059] In this embodiment, the vibration transmission assembly is arranged as the elastic component 121 having the first through hole and the connecting component 122 capable of covering the first through hole. On the one hand, the amplitude and vibration direction of the voice coil can be limited without being limited too much; on the other hand, the voice coil can be fixedly connected to the external contact component, and dust can be prevented from entering the voice coil.

[0060] The embodiments of the present application also provide an electronic device, such as Figures 5-6 As shown, it comprises:

[0061] a first sound production module 41; the first sound production module 41 comprises a vibration transmission assembly 411;

[0062] a housing 42; the housing 42 comprises a first region 421 and a second region 422; the first region 421 is movably connected with the second region 422; the housing 42 has a cavity, the first sound production module 41 is arranged in the cavity, and the vibration transmission assembly 411 of the first sound production module 41 is connected with the lower surface of the second region 422, so that when the first sound production module 41 vibrates based on the received first audio signal, the second region 422 is driven to vibrate by the vibration transmission assembly 411 to drive the air to vibrate, and the audio corresponding to the first audio signal is output.

[0063] In some embodiments, the first sound production module 41 further comprises a driving assembly 11, the driving assembly 11 comprising a magnetic circuit module 111 and a voice coil 112; the magnetic circuit module 111 is configured to generate a first magnetic field; the voice coil 112 is configured to receive an audio signal, generate a second magnetic field based on the audio signal, and vibrate in a first direction under the interaction of the first magnetic field and the second magnetic field; the first direction is the connection direction of the magnetic circuit module 111 and the voice coil 112. The vibration transmission assembly 411 is arranged on the voice coil 112 and is configured to transmit the vibration of the voice coil 112 to the second area 422 of the electronic device shell 42.

[0064] In some embodiments, as shown in Figure 5 The number of first sound production modules 41 can be even, and the even number of first sound production modules 41 are symmetrically arranged, so as to form left and right sound channels and improve user experience.

[0065] In some embodiments, the shell 42 can be a screen surface shell of the electronic device, can be a keyboard surface shell of the electronic device, or can be a combination of the screen surface shell and the keyboard surface shell of the electronic device.

[0066] In specific implementation, when the shell 42 is a screen surface shell of the electronic device, the second area 422 can be arranged at the lower left corner, the lower right corner, or both the lower left corner and the lower right corner of the screen surface shell. When the shell 42 is a keyboard surface shell of the electronic device, the second area 422 can be arranged at the upper left corner, the upper right corner, or both the upper left corner and the upper right corner of the keyboard surface shell. When the shell 42 is a combination of the screen surface shell and the keyboard surface shell of the electronic device, the second area 422 can be arranged at the lower left corner, the lower right corner, or both the lower left corner and the lower right corner of the screen surface shell, or at the upper left corner, the upper right corner, or both the upper left corner and the upper right corner of the keyboard surface shell, or at both the lower left corner and the lower right corner of the screen surface shell and at both the upper left corner and the upper right corner of the keyboard surface shell.

[0067] In some embodiments, as shown in Figure 6 The first area 421 can be arranged in a groove structure, so that the second area 422 can be placed in the groove of the first area 421, facilitating the placement of the first area. The first area and the second area are movably connected by means of glue, buckles, etc., so that the second area can vibrate slightly.

[0068] In some embodiments, as shown in Figure 6 The upper surfaces of the first area 421 and the second area 422 are flush, so that the upper surfaces of the first area 421 and the second area 422 are a flat plane, thereby meeting the design requirements of the clean surface of the electronic device and improving user experience.

[0069] In some embodiments, as shown in Figure 7As shown, the electronic device also includes a computing unit 801 that can perform various appropriate actions and processes in accordance with a computer program stored in a read-only memory (ROM) 802 or a computer program loaded from the storage unit 808 into a random access memory (RAM) 803. Various programs and data required for the operation of the device 800 can also be stored in the RAM 803. The computing unit 801, the ROM 802, and the RAM 803 are connected to each other through a bus 804. An input / output (I / O) interface 805 is also connected to the bus 804.

[0070] A plurality of components in the electronic device are connected to the I / O interface 805, including: an input unit 806, such as a keyboard, a mouse, etc.; an output unit 807, such as various types of displays, a speaker, etc.; a storage unit 808, such as a magnetic disk, an optical disk, etc.; and a communication unit 809, such as a network card, a modem, a wireless communication transceiver, etc. The communication unit 809 allows the electronic device to exchange information / data with other devices through a computer network, such as the Internet, and / or various telecommunication networks.

[0071] It should be noted that the electronic device is intended to represent various forms of digital computers, such as laptops, desktops, workstations, personal digital assistants, servers, blade servers, mainframes, and other appropriate computers. The electronic device can also represent various forms of mobile devices, such as personal digital processors, cellular telephones, smart phones, wearable devices, and other similar computing devices. The description of the electronic device in the present embodiment is only exemplified by a notebook computer, but is not limited thereto.

[0072] The electronic device provided in the present embodiment sets the sound emitting module to include a vibration transmission assembly, the vibration transmission assembly is used to transmit the vibration of the sound emitting module to the second region of the electronic device shell, so as to drive the air vibration through the vibration of the second region, and output the audio corresponding to the first audio signal; in this way, the audio corresponding to the first audio signal can be output without opening the front surface of the electronic device, so that the electronic device is designed without sound hole, and perfectly meets the requirement of clean surface design of the electronic device; and because the sound emitting module drives the vibration of the second region to drive the air vibration to emit the audio corresponding to the first audio signal, the sound emitting rate of the sound emitting module can be infinite, the high-frequency audio signal can be responded, the high frequency can be up to 20 kHz, so that the high-frequency sound can be better restored, and the user experience is improved.

[0073] In an optional embodiment, as shown in Figure 8 The electronic device also includes:

[0074] The second sound module 43 is used to receive the second audio signal and output the audio corresponding to the second audio signal, wherein the frequency of the first audio signal is greater than the frequency of the second audio signal.

[0075] In some embodiments, the first audio signal and the second audio signal can be obtained by frequency division of the target audio signal.

[0076] In some embodiments, since the frequency of the audio output by the second sound module 43 is lower than the frequency of the audio output by the first sound module 41, the first sound module 41 can be configured to output high-frequency sounds, and the second sound module 43 can be configured to output low-frequency sounds. Since the second sound module 43 is used to output low-frequency sounds, it does not need to be positioned on the front of the electronic device; therefore, the second sound module 43 can be positioned on the bottom of the electronic device. Specifically, the second sound module 43 can output the audio corresponding to the second audio signal through an opening. The second sound module can be a conventional speaker.

[0077] In some embodiments, such as Figure 8 As shown, the electronic device may also include a controller 44, such as an integrated Southbridge (Platform Controller Hub, PCH), for decoding music or other sounds played by the electronic device to obtain digital audio. The electronic device also includes an audio encoder 45 for converting the digital audio into an analog signal to obtain a target audio signal, and then dividing the target audio signal by frequency. The electronic device further includes a first amplifier 46 and a second amplifier 47, whereby the first amplifier 46 amplifies the first audio signal input to the first sound-generating module 41, and the second amplifier 47 amplifies the second audio signal input to the second sound-generating module 43.

[0078] In specific implementation, such as Figure 9 As shown, audio signals above 8000Hz are mainly output through the first sound-generating module. Audio signals below 8000Hz are also mainly output through the first sound-generating module.

[0079] In this embodiment, by setting the audio corresponding to the second audio signal output by the second sound module, the electronic device can output sounds of different frequencies through different sound modules, thereby improving the sound reproduction effect.

[0080] In an optional embodiment, such as Figure 8 As shown, the electronic device also includes:

[0081] The detection component 48 is disposed on the lower surface of the second region 422, away from the first sound-emitting module 41, and is used to sense the touch signal of an external object on the second region 422.

[0082] The controller 44 is configured to control the first sound generating module 41 to stop working based on the touch signal.

[0083] In practice, the detection component 48 can be a touch sensor, a pressure sensor, or the like. The detection component 48 is arranged on the lower surface of the second area 422 away from the first sound generating module 41. The detection component 48 can be arranged at a distance from the first sound generating module 41 and surround the first sound generating module 41.

[0084] In some embodiments, the external object can be a user or an external object.

[0085] In some embodiments, the controller 44 is configured to determine the pressure on the first sound generating module based on the touch signal, and control the first sound generating module 41 to stop working when the pressure is greater than a threshold.

[0086] In some embodiments, the controller 44 is configured to cut off the first audio signal based on the touch signal to control the first sound generating module 41 to stop working.

[0087] In some embodiments, when the detection component 48 does not detect the touch signal, the controller 44 is further configured to control the first sound generating module 41 to resume working.

[0088] In this embodiment, by arranging the detection component 48 to detect the touch signal of the external object on the second area 422, and by arranging the controller 44 to control the first sound generating module 41 to stop working when the touch signal is obtained, the external object can not feel vibration when touching the second area.

[0089] The embodiments of the present application also provide a control method applied to an electronic device. The electronic device includes a first sound generating module and a shell. The first sound generating module includes a vibration transmission component. The shell includes a first area and a second area. The vibration transmission component of the first sound generating module is connected to the lower surface of the second area. As shown in Figure 10 The method includes the following steps.

[0090] S101, obtaining a first audio signal.

[0091] S102, sending the first audio signal to the first sound generating module, so that the first sound generating module drives the second area of the shell of the electronic device to vibrate based on the first audio signal, drives air to vibrate, and emits an audio corresponding to the first audio signal.

[0092] In some embodiments, the first sound production module further includes a driving assembly. The driving assembly includes a magnetic circuit module and a voice coil. The magnetic circuit module is configured to generate a first magnetic field. The voice coil is configured to receive an audio signal, generate a second magnetic field based on the audio signal, and vibrate in a first direction under interaction of the first magnetic field and the second magnetic field. The first direction is a connection direction of the magnetic circuit module and the voice coil. The vibration transmission assembly is arranged on the voice coil and configured to transmit vibration of the voice coil to the second area of the electronic device housing.

[0093] In some embodiments, the electronic device can further include a controller and an audio encoder. The controller is configured to decode music or other sound played by the electronic device to obtain digital audio. The audio encoder is configured to convert the digital audio into an analog signal to obtain a target audio signal.

[0094] In implementation, for step S101, the electronic device can directly receive the first audio signal of the external sound production, or decode music or other sound played by the electronic device through the controller to obtain digital audio. Then the digital audio is converted into an analog signal through the audio encoder to obtain the first audio signal.

[0095] In some embodiments, the audio encoder is further configured to frequency-division the analog signal to obtain a first audio signal of high frequency and a second audio signal of low frequency.

[0096] In implementation, for step S102, after obtaining the first audio signal, the electronic device sends the first audio signal to the first sound production module. The first sound production module receives the first audio signal, generates a second magnetic field based on the audio signal, vibrates in a first direction under interaction of the first magnetic field and the second magnetic field, drives the second area to vibrate through the vibration transmission assembly, drives air to vibrate, and emits audio corresponding to the first audio signal.

[0097] The control method provided by the embodiments of the present application sets that the first sound production module includes a vibration transmission assembly connected with the second area of the electronic device housing. In this way, when the first sound production module receives the first audio signal and vibrates based on the first audio signal, the second area of the electronic device housing can be driven to vibrate to drive air to vibrate and emit audio corresponding to the first audio signal, so that the audio corresponding to the first audio signal can be output without opening the front of the electronic device, thereby realizing the sound hole-free design of the electronic device and perfectly meeting the demand of the clean surface design of the electronic device. Because the first sound production module drives the second area of the electronic device housing to vibrate to drive air to vibrate and emit the audio corresponding to the first audio signal, the sound output rate of the first sound production module can be infinite, can respond to high-frequency audio signals, and can respond to high frequencies up to 20 kHz, so that the high-frequency sound can be better restored and the user experience can be improved.

[0098] In an optional embodiment, the electronic device further comprises a second sound emitting module, and the method further comprises:

[0099] S103, obtaining a second audio signal; the frequency of the first audio signal is greater than the frequency of the second audio signal;

[0100] S104, sending the second audio signal to the second sound emitting module, so as to output the audio corresponding to the second audio signal through the second sound emitting module.

[0101] In some embodiments, the first sound emitting module is used to play high-frequency sound, and the second sound emitting module is used to play low-frequency sound.

[0102] In some embodiments, for step S103, the first audio signal and the second audio signal are obtained by frequency division of a target audio signal.

[0103] In implementation, for step S103, the target audio signal can be frequency-divided by an audio encoder to obtain the first audio signal of high frequency and the second audio signal of low frequency.

[0104] For step S104, the audio encoder sends the second audio signal to the second sound emitting module, the second sound emitting module receives the second audio signal, and outputs the audio corresponding to the second audio signal.

[0105] In this embodiment, by setting the second sound emitting module to output the audio corresponding to the second audio signal, the electronic device can output sound of different frequencies through different sound emitting modules, thereby improving the sound restoration effect.

[0106] In an optional embodiment, the control method further comprises: obtaining a touch signal of an external object to the second area, and controlling the first sound emitting module to stop working.

[0107] In implementation, the electronic device further comprises a detection component arranged on the lower surface of the second area and away from the first sound emitting module, and used to sense the touch signal of the external object to the second area. When the touch signal of the external object to the second area is obtained, the controller can control the first sound emitting module to stop working.

[0108] In this embodiment, when the touch signal of the external object to the second area is obtained, the first sound emitting module is controlled to stop working, so that the external object does not have a vibration feeling when touching the second area.
