Description

Technical Field

[0001] The present disclosure relates to the technical field of electronic equipment, and in particular to a speaker structure and an electronic equipment. Background Art

[0002] The traditional way of fixing speaker units usually causes the problem of speaker module vibration. From a system level, in order to solve the problem of speaker module vibration, sound designers have to adopt the following three solutions: the first is to actively offset the vibration of the reverse membrane surface through the design of the upper and lower double membrane surfaces of the speaker unit; the second is to attach vibration-damping materials between the speaker module and the corresponding counterpart to reduce the structural vibration of the speaker module caused by the vibration transmitted to the system end; the third is to limit the volume output and reduce the maximum volume of the speaker set by the system.

[0003] However, in the first of the above solutions, the thickness of the double-membrane surface unit will increase, thus affecting the design of the system space. It is difficult for thin and light notebook computers to use such speaker units. In the second solution, its attachment quality depends on the flatness of the speaker module surface. If it is an irregular shape, it will increase the difficulty of attachment and molding, and also increase the production cost. The third solution affects the rights of users to enjoy high volume and high sound quality experience. In addition, notebook computers are gradually designed in the direction of being thin and high-performance. The space in the notebook computer system can be said to be very valuable, so the design situation of overlapping parts often occurs. In addition to providing the cavity size required by the speaker unit, signal routing and the structure required for shell production, the utilization rate of the internal space in the speaker module needs to be further improved.

DETAILED DESCRIPTION

[0031] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0032] Reference Figure 1 to Figure 4 As shown, a speaker structure of an exemplary embodiment of the present invention includes a frame 1, a sound membrane assembly 2, a magnetic induction assembly 3 and an elastic assembly 4. The sound membrane assembly 2 is connected to the top surface of the frame 1 for generating a sound field. The magnetic induction assembly 3 is located in the frame 1. The magnetic induction assembly 3 generates a reciprocating magnetic field force according to the electric energy passing therethrough to push the sound membrane assembly 2 to vibrate reciprocatingly, causing the air to vibrate and generate sound waves. The elastic assembly 4 is arranged on the bottom surface of the frame 1. The elastic assembly 4 carries the magnetic induction assembly 3 and can absorb vibrations through elastic deformation.

[0033] In one embodiment, the magnetic induction component 3 includes a voice coil 31, a magnet 32 ​​and an iron core 33. The iron core 33 is supported on the elastic component 4 and separated from the frame 1. The magnet 32 ​​is located below the sound membrane component 2. The voice coil 31 is arranged around the magnet 32 ​​and is located on the inner periphery of the iron core 33.

[0034] In this embodiment, the frame 1 is used as a supporting structure to fix and support the components in the speaker structure. It is usually made of strong materials such as metal or plastic, and has good rigidity and stability. The sound membrane assembly 2 is used to directly push the air to produce sound, usually a diaphragm. The sound cone is a specific form of the diaphragm. It is usually made of paper, plastic, metal or other special materials, and has good rigidity and toughness. Specifically, when the audio signal is input through the terminal of the speaker structure and drives the voice coil 31, the voice coil 31 will be affected by the force in the magnetic field and vibrate. This vibration is then transmitted to the sound cone, causing the sound cone to also vibrate accordingly. Since the area of ​​the sound cone is relatively large, it can more effectively convert the vibration into sound waves and radiate it to the surrounding space. Among them, the iron core 33 is a magnetic conductive component, which forms a magnetic circuit together with the magnet 32. The iron core 33 has a magnetic conductive effect and can enhance the magnetic field generated by the magnet 32, making the magnetic field more uniform and stable. The magnet 32 ​​is usually made of permanent magnet material, including but not limited to ferrite or neodymium iron boron, etc. The magnet 32 ​​and the iron core 33 form a uniform magnetic circuit to provide the necessary magnetic field environment for the voice coil 31. The voice coil 31 is located in the magnetic field and is wound by a wire. When the audio signal passes through the speaker structure, the current will flow through the voice coil 31, thereby generating a force in the magnetic field and causing the voice coil 31 to vibrate. In summary, the specific pronunciation process of the speaker structure is that when the speaker structure receives an audio signal, the current passes through the voice coil 31. The voice coil 31 generates a magnetic field reaction in the magnetic field generated by the magnet 32 ​​due to the action of the current. Since the alternating current passes through the coil, the positive and negative poles are constantly changing, causing the voice coil 31 to reciprocate in the magnetic field; the reciprocating motion of the voice coil 31 drives the connected sound membrane assembly 2 to vibrate, and drives the surrounding air to generate sound waves and airflow, thereby producing sound. The frequency and amplitude of the sound are determined by the input audio signal. Different frequency components in the audio signal will drive the diaphragm to vibrate at different frequencies, thereby emitting sounds of different tones. The elastic component 4 is fixed to the bottom surface of the frame 1 and carries the magnetic induction component 3. Its function is that when the speaker structure vibrates, the elastic component 4 can convert the vibration energy into its own elastic potential energy and consume the energy through its own elastic deformation, thereby reducing the impact of the vibration on the speaker structure. That is, the elastic component 4 can absorb the vibration originally transmitted from the magnetic induction component 3 to the frame 1 through the above characteristics, which can effectively absorb the vibration energy and reduce the structural vibration sound of the speaker structure and reduce abnormal sound.

[0035] Reference Figures 5 to 8 , Fig.10 As shown, in one embodiment, the elastic component 4 includes a supporting portion 41 and an elastic portion 42 . The supporting portion 41 is fixedly connected to the frame 1 for supporting the magnetic induction component 3 , and the elastic portion 42 is disposed on the supporting portion 41 .

[0036] Specifically, in one embodiment, the elastic portion 42 has an initial state and a deformed state. When the elastic portion 42 is in the initial state, the support portion 41 and the elastic portion 42 are located in the same plane. When the elastic portion 42 is in the deformed state, the elastic portion 42 undergoes elastic deformation in a direction away from or close to the magnetic induction component 3.

[0037] In this embodiment, the support portion 41 is welded and fixed to the frame 1, the iron core 33 is supported on the support portion 41 and a gap is formed between the support portion 41 and the frame 1, and the elastic portion 42 can be elastically deformed. Since the vibration of the frame 1 usually has a negative impact on the sound quality, such as causing sound distortion, the vibration of the frame 1 may also cause the sound of certain frequency bands to be suppressed or enhanced, thereby affecting the frequency response characteristics of the speaker structure, and then affecting the overall sound quality. Long-term vibration of the frame 1 may also cause the connection between the various components to loosen or be damaged, thereby shortening the service life of the speaker structure. Therefore, by welding the support portion 41 of the elastic component 4 to the frame 1, the support portion 41 supports the magnetic induction component 3 as a whole and specifically separates the iron core 33 from the frame 1, so that the vibration of the magnetic induction component 3 can be absorbed by the elastic component 4, effectively reducing the vibration transmitted to the frame 1. The elastic portion 42 is defined as the normal state when the elastic portion 42 is not deformed when it is in the initial state, so when the elastic portion 42 is in the initial state, the support portion 41 and the elastic portion 42 are located in the same plane. When the elastic part 42 is elastically deformed, the maximum displacement of the end of the elastic part 42 away from the end fixedly connected to the support part 41 can be 2.4×10 -9 mm. It is understandable that the 2.4×10 -9 mm is not absolutely 2.4×10 -9 mm, there can be a slight deviation within the tolerance range, and the maximum displacement is not limited to this, and will vary accordingly depending on the material and structure of the elastic component 4.

[0038] In one embodiment, the support portion 41 has a connection end 411 fixedly connected to the frame 1 and an extension section 412 extending from at least part of the connection end 411 , the extension section 412 is in contact with the magnetic induction component 3 , and the elastic portion 42 is fixedly connected to part of the connection end 411 .

[0039] Furthermore, in one embodiment, the elastic portion 42 is U-shaped, the extending section 412 is located in the U-shaped space of the elastic portion 42 , and there is a gap between the elastic portion 42 and the extending section 412 .

[0040] In this embodiment, the extension section 412 is specifically in contact with the iron core 33, and the number of the connection ends 411 can be one or more. When the number of the connection ends 411 is one, the extension section 412 extends from at least part of the connection end 411, and the elastic part 42 is fixedly connected to part of the connection end 411 and is located beside the extension section 412, and can be elastically deformed relative to the connection end 411. When the number of the connection ends 411 is two, one of the connection ends 411 is defined as the first end 4111, and the other connection end 411 is defined as the second end 4112. At this time, the elastic part 42 can be U-shaped, one end of the U-shaped elastic part 42 is connected to the first end 4111, and the other end of the U-shaped elastic part 42 is connected to the second end 4112. The extension section 412 extends from the first end 4111 and is located in the U-shaped space of the U-shaped elastic part 42. Since there is a gap between the elastic part 42 and the extension section 412, the elastic part 42 can be elastically deformed relative to the extension section 412.

[0041] CC is the abbreviation of cubic centimeters, which is a unit of volume. Compared with the original design, in the same standard box, the internal effective volume of the speaker structure of the present invention is 3.8CC, and the internal effective volume in the original design is 4.0CC. As for the design of the speaker structure, this difference does not affect the final acoustic design, because 0.2CC can be compensated by adjusting the thickness design of the speaker structure or the debugging of the software. Even if the difference of 0.2CC is accepted, the quality and size of the sound of the speaker structure are not affected. In addition, the present invention can not only effectively reduce the structural vibration sound of the speaker structure by about 4.2dB, but also, when debugging the system sound effect, the reduction of the structural vibration sound generated by the frame 1 does not require the original design volume to be reduced, but a higher system volume can be obtained, which improves the user's auditory experience; in addition, because the amount of vibration-damping materials is reduced, the manufacturing cost is also reduced. After the speaker structure in the present invention is provided with an elastic component 4, the vibration sound generated by the speaker structure as a whole and the sound reduction effect compared with the original design are shown in Table 1.

[0042] Table 1 Comparison of vibration and sound reduction effects between the present invention and the original design

[0043] Speaker structure design Structural-acoustic noise of the speaker structure (dB) Noise reduction effect (dB) Original speaker structure 56.2 - Speaker structure of the present invention 52.0 4.2

[0044] Among them, in Table 1, in the originally designed speaker structure, the structural vibration sound generated is 56.2dB. In the speaker structure of the present invention, since the elastic component 4 is fixedly connected to the frame 1, the elastic component 4 supports and separates the magnetic induction component 3 and the frame 1, so that the vibration energy generated by the magnetic induction component 3 is partially absorbed by the elastic component 4. Therefore, the structural vibration sound generated by the speaker structure of the present invention is 52.0dB, which produces a 4.2dB sound reduction effect compared with the originally designed speaker structure.

[0045] In addition, the elastic component 4 in the present invention can also play a partial signal receiving function, specifically, by connecting the F-type antenna to the elastic component 4 and the wireless network card, the wireless communication function can be played. Among them, the F-type antenna is a planar antenna, and its shape is similar to the inverted form of the letter F. It is composed of a radiating metal sheet, a short-circuit metal sheet and a grounding part. It is usually designed on the top layer of the circuit board, and the grounding layer is placed near the antenna. Its working principle is based on electromagnetic induction and electromagnetic wave radiation. When current passes through the radiating metal sheet, an electromagnetic field will be generated around it, and then electromagnetic waves will be radiated. The short-circuit metal sheet and the grounding part play a role in adjusting the antenna impedance and improving the radiation characteristics. F-type antennas are usually used in wireless communication devices, such as mobile phones, tablet computers or laptops. F-type antennas are often used in Bluetooth, WIFI and other wireless communication functions of the above-mentioned devices. When the elastic component 4 performs the signal receiving function, taking the signal receiving of the wireless network as an example, the specific signal receiving process is: signal reception, the F-type antenna receives the wireless network signal through its unique structure and design; signal transmission, the received signal is transmitted to the elastic component 4 through the F-type antenna, and further connected to the wireless network card; signal processing, the wireless network card decodes and processes the received signal and converts it into a format that can be recognized by the computer or other devices; wireless network connection, the processed signal enables the computer or other devices to connect to the wireless network to realize data transmission and communication. After actual measurement, when using the speaker structure to play sound, wireless communication functions such as Bluetooth and WIFI are not affected. Therefore, such a structural design can effectively utilize space, integrate the signal receiving function, and enhance the competitiveness of the product.

[0046] Reference Fig.11 As shown, in one embodiment, a fixing protrusion 4121 for connecting with the magnetic induction component 3 is protruded from one side of the extension section 412 close to the magnetic induction component 3 .

[0047] In this embodiment, the extension section 412 is provided with a fixing protrusion 4121, and accordingly, a fixing slot can be provided on one side where the core 33 is fixed to the extension section 412, for engaging and fixing with the fixing protrusion 4121, so that the core 33 is stably connected to the extension section 412. It is understandable that the extension section 412 can also be connected to the core 33 by other means, such as but not limited to gluing, embedding or welding.

[0048] In one embodiment, a supporting platform 11 is provided on the inner periphery of the frame 1, the voice coil 31 is limited by the supporting platform 11 and is in contact with the sound membrane assembly 2. When the voice coil 31 vibrates along its axial direction, it can drive the sound membrane assembly 2 to vibrate synchronously.

[0049] In this embodiment, when an audio signal is input through the terminal of the speaker structure and drives the voice coil 31, the voice coil 31 will be affected by the force in the magnetic field and vibrate. Since the voice coil 31 is connected to the sound membrane assembly 2, the vibration is then transmitted to the sound membrane assembly 2, causing the sound membrane assembly 2 to also vibrate accordingly, pushing the surrounding air to generate sound waves and airflow, thereby making sound.

[0050] Reference Fig. 9 As shown, in one possible implementation manner, the number of elastic components 4 is four groups, and the four groups of elastic components 4 are evenly arranged with the frame 1 .

[0051] In this embodiment, the connection ends 411 of the support parts 41 in the four groups of elastic components 4 are all welded and fixed to the frame 1, and the elastic parts 42 in the elastic components 4 are located below the iron core 33. The four elastic parts 42 are arranged relatively to fully absorb vibration.

[0052] The present disclosure also provides an electronic device, including a housing, and also including a speaker structure as in any one of the above-mentioned embodiments, wherein the speaker structure is arranged in the housing.

[0053] In this embodiment, the electronic device may include but is not limited to a laptop computer, a tablet computer or a mobile phone, etc. According to different application requirements, the speaker structure may be designed to be of different sizes and shapes to adapt to different audio ranges and volume requirements. Since the electronic device of the present invention is provided with a speaker structure in the housing, an elastic component 4 is provided on the bottom surface of the frame 1 in the speaker structure, and the elastic component 4 carries the magnetic induction component 3, the elastic component 4 can absorb the vibration originally transmitted from the magnetic induction component 3 to the frame 1 through its own resonance behavior, and can effectively absorb the vibration energy and reduce the structural vibration sound of the speaker structure, thereby reducing abnormal sound.
