Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
According to an aspect of an embodiment of the present invention, there is provided a sound processing apparatus 1. The sound processing apparatus 1 may be applied to a corresponding scene of an electronic device, for example, the sound processing apparatus 1 may be applied to an earpiece assembly in the electronic device, or the sound processing apparatus 1 may be applied to a speaker for emitting sound in the electronic device, or the like.
As shown in fig. 1, the sound processing apparatus 1 may include: a tank body 101, a permanent magnet 102, an elastic air gap pad 103 and a sound diaphragm 104.
The permanent magnet 102 may be disposed in the tank body 101 and above the bottom of the tank body 101, the elastic air gap pad 103 is disposed above the permanent magnet 102, and the sound diaphragm 104 is disposed above the elastic air gap pad 103.
The sound diaphragm 104 and the elastic air gap pad 103 have a predetermined distance greater than 0. The preset distance between the sound film 104 and the elastic air gap pad 103 is designed to be greater than 0, so that a certain vibration space is formed on one side of the sound film 104 facing the elastic air gap pad 103, and the sound film 104 is prevented from colliding with the elastic air gap pad 103 in the vibration process. It is understood that the preset distance may be set according to the maximum vibration amplitude of the sound membrane 104, and the specific preset distance is not limited by the embodiment of the present invention.
The permanent magnet 102 can provide a constant magnetic field, and the sound film 104 can play a sound producing function, which can generate an alternating magnetic field under the action of audio frequency alternating current. The alternating magnetic field generated by the sound film 104 and the constant magnetic field generated by the permanent magnet 102 repel or attract each other, so as to drive the sound film 104 to vibrate, and the sound film 104 extrudes air to make a sound.
The slot 101 may be used as a carrier for the permanent magnet 102, the elastic air gap pad 103, etc. In addition, the tank 101 may also perform a sound pressure spring function with respect to the sound diaphragm 104. The sound pressure generated by the diaphragm 104 on the side facing the elastic air gap pad 103 (i.e. the back of the diaphragm 104, also called the diaphragm back chamber) during vibration causes the gas on the back of the diaphragm 104 to be compressed by the resistance of the side wall of the groove 101, and the compressed gas has a reaction force (i.e. damping) acting as a spring on the body of the diaphragm 104. The reaction force of the compressed gas (i.e., the force of the acoustic spring) may cause the diaphragm 104 to obtain a more free amplitude, which is beneficial for the bass performance of the speaker.
The elastic air gap pad 103 is disposed between the permanent magnet 102 and the diaphragm 104. When the sound wave generated at the back of the sound film 104 impinges on the elastic air gap pad 103, the elastic air gap pad 103 has certain elasticity and good buffering performance, so that the sound wave can be damped, and the elastic air gap pad 103 can also damp the sound wave in the process that the sound wave passes through the elastic air gap pad 103, thereby consuming the energy of the sound wave and attenuating the sound wave.
Wherein, the high frequency signal is short wave, after hitting the elastic air gap 103 pad, a part of sound wave will pass through the elastic air gap 103 pad, the elastic air gap 103 block the sound wave transmission, consume the sound wave energy; another part of the sound wave will be reflected on the elastic air gap pad 103, and the sound wave energy will be consumed by the buffering action of the elastic air gap pad 103. The low-frequency signal is a long wave, and after the low-frequency signal strikes the elastic air gap pad 103, the low-frequency signal mainly makes diffraction movement around the surface of the air gap pad, and forms an acoustic spring in the air of the rear cavity of the sound film through radiation, so that the sound film 104 can obtain more free amplitude, and the bass of the loudspeaker can be played. Therefore, in the embodiment of the present invention, under the action of the elastic air gap pad 103, the high frequency signal can be attenuated, the low and medium frequency signals are more prominent after the high frequency signal is attenuated, and the voice signal is mainly in the low and medium frequency range, which is beneficial to the user to listen to the sound. In addition, the attenuation of the high frequency signal can also reduce the probability of occurrence of glitch signals and distortion. Furthermore, under the damping action of the elastic air gap pad 103 on the reflection of the sound waves, the occurrence of echoes can be reduced, and the improvement of the sound quality is facilitated.
Optionally, the interior of the resilient air gap pad 103 may be filled with a liquid medium. The sound waves are transmitted in different media at different transmission speeds, so that the sound waves are transmitted in different media, and a better damping and eliminating effect can be formed on the sound waves. The liquid media described herein may include, but are not limited to: water and oil, wherein the oil may be a vegetable oil.

In fig. 2, the upper diagram is a front view of the permanent magnet 102, and the lower diagram is a side view of the permanent magnet 102.
The first protrusions 1021 may be preferably arranged in a honeycomb shape and uniformly distributed on the permanent magnet 102, so as to further enable the permanent magnet 102 to generate a uniform magnetic field. The shape of the first protrusion 1021 may be a square column structure, or a sawtooth structure, and the specific situation may be selected according to actual needs, which is not limited in the embodiment of the present invention.
The materials of the permanent magnet 102 may include, but are not limited to: neodymium iron boron or ferrite, and the common neodymium iron boron can be preferably used. The size of the permanent magnet 102 may be determined according to the requirements of the electronic device to which it is applied.

Alternatively, the surface of the elastic air gap pad 103 on the side facing the permanent magnet 102 may be smooth, and a plurality of second protrusions 1031 may be provided, as shown in fig. 1 and 3. The second protrusions may increase the surface area and partial thickness of the elastomeric air gap pad 103 to enhance the ability to attenuate acoustic energy. In fig. 3, the upper diagram is a front view of the elastic air gap pad 103, and the lower diagram is a side view of the elastic air gap pad 103.
In the case that the permanent magnet 102 is provided with a plurality of first protrusions 1021 on the side facing the elastic air gap pad 103, when the elastic air gap pad 103 is engaged with the permanent magnet 102, the second protrusions 1031 on the elastic air gap pad 103 are disposed in the first recesses 1022 formed between the first protrusions 1021, and the first protrusions 1021 on the permanent magnet 102) are disposed in the second recesses 1032 formed between the second protrusions 1031 on the elastic air gap pad 103. The second protrusions 1031 may have a square columnar structure, a saw-toothed structure, or the like, and the specific situation may be selected according to actual requirements, which is not limited in the embodiment of the present invention.

Wherein, the plastic material includes but is not limited to: polyvinyl chloride (PVC), Polyamide (PA), or Polyethylene (PE). The length of the resilient air-gap pad 103 may range from 68mm to 75mm, preferably 73 mm. The thickness of the resilient air-gap pad 103 may range from 1.5mm to 3mm, and preferably 2 mm.
Optionally, a metal sheet 105 may be disposed between the bottom of the tank 101 and the permanent magnet 102, and mainly functions to reduce magnetic leakage. The material of the metal sheet 105 may include but is not limited to: iron or alloy steel, preferably lower cost iron.
The length and width of the metal plate 105 can be set according to the size of the permanent magnet 102, and the thickness can range from 0.14mm to 0.18mm, and preferably 0.16 mm. The shape of the metal sheet 105 can be set according to the shape of the permanent magnet 102, for example, when the permanent magnet 102 is square, the shape of the metal sheet 105 can be set to be square correspondingly; when the permanent magnet 102 has an oval shape, the metal piece 105 may have an oval shape.
Alternatively, as shown in fig. 4, the sound film 104 may include: a diaphragm 1041 and an electromagnetic induction wire 1042, the electromagnetic induction wire 1042 is disposed on a side of the diaphragm 1041 facing the elastic air gap pad 103. The sound film 104 combines the electromagnetic induction wire 1042 and the diaphragm 1041, and when an audio current is applied to the electromagnetic induction wire 1042 on the sound film 104, the diaphragm 1041 is forced to vibrate and sound through the interaction between the alternating magnetic field generated by the change of the current signal in the electromagnetic induction wire 1042 and the constant magnetic field generated by the permanent magnet 102.
The electromagnetic induction wires 1042 may be uniformly laid on the diaphragm 1041 to make the magnetic circuit uniform and reduce acoustic distortion. The pattern formed by tiling the electromagnetic induction wires 1042 can be determined according to the shape of the diaphragm 1041, and if the diaphragm 1041 is square, the pattern formed by tiling the electromagnetic induction wires 1042 can be set to be square; the diaphragm 1041 is oval, and the pattern formed by tiling the electromagnetic induction wires 1042 can be set to be oval. The total length of the electromagnetic induction wire 1042 may range from 75mm to 85mm, preferably 80mm, and the width of the pattern formed thereon may range from 10mm to 15mm, preferably 12 mm. The material of the electromagnetic induction wire 1042 may include but is not limited to: copper wire or aluminum wire.
In the embodiment of the present invention, in order to improve the solidity of the membrane 1041, the membrane 1041 may be composed of three layers, which may be: polyamide layer, copper foil layer and bulletproof cloth layer, wherein the copper foil layer sets up between polyamide layer and bulletproof cloth layer, and polyamide layer sets up towards permanent magnet 102. The three-layer structure may also be: the first layer structure is a polypropylene layer or a rubber layer, the second layer structure is an aluminum-magnesium alloy layer or a carbon fiber layer, the third layer structure is a glass fiber layer or a paper layer, and the selection of the materials of the three layers can be determined according to actual requirements.

In summary, in the embodiment of the present invention, the slot 101 in the sound processing apparatus 1 can be used as a carrier of structures such as the permanent magnet 102 and the elastic air gap pad 103. The interaction between the permanent magnet 102 and the sound diaphragm 104 drives the sound diaphragm 104 to vibrate so as to make the sound diaphragm 104 sound. The elastic air gap pad 103 arranged between the permanent magnet 102 and the sound film 104 can attenuate high-frequency signals, highlight middle and low-frequency signals and facilitate the user to hear sound. In addition, the attenuation of the high-frequency signals can reduce the probability of generating the burr signals, reduce distortion and improve the tone quality. Furthermore, under the damping action of the elastic air gap pad 103 on the reflection of sound waves, the occurrence of echoes can be reduced, and the sound quality is improved. In addition, the sound processing device 1 has the advantages of simple and practical structure, easy manufacture, low technical requirement threshold and convenient production.
According to another aspect of embodiments of the present invention, there is provided an electronic device, which may include but is not limited to: the mobile phone, the television, the desktop computer, the tablet computer, the personal digital assistant, the wearable watch, the electric toy and other devices which need to generate sound.
The electronic device may include: a mounting hole 2 opened on the electronic device, a device case 3, and the sound processing apparatus 1 according to the above embodiment.
Wherein, the groove body 101 in the sound processing device 1 is arranged inside the equipment shell 3, and the sound film 104 in the sound processing device 1 is connected with the hole wall of the mounting hole 2.
In the embodiment of the present invention, the tank 101 in the sound processing device 1 may be used as a carrier of structures such as the permanent magnet 102 and the elastic air gap pad 103. The interaction between the permanent magnet 102 and the sound diaphragm 104 drives the sound diaphragm 104 to vibrate so as to make the sound diaphragm 104 sound. The elastic air gap pad 103 arranged between the permanent magnet 102 and the sound film 104 can attenuate high-frequency signals, highlight middle and low-frequency signals and facilitate the user to hear sound. In addition, the attenuation of the high-frequency signals can reduce the probability of generating the burr signals, eliminate acoustic short circuits, inhibit acoustic resonance, widen the frequency response range and improve the tone quality.
Alternatively, as shown in fig. 5 and fig. 6, the mounting hole 2 may be opened on a frame 301 of the device housing 3, and the sound film 104 may be flush with an outer surface of the frame 301 having the mounting hole 2, so that the sound processing apparatus 1 no longer occupies a front space of the electronic device, which is beneficial to increasing a screen occupation ratio of the screen 4. In addition, in the embodiment of the present invention, the sound film 104 is directly disposed on the frame 301, and becomes a part of the frame 301, and serves two functions of the frame 301 and the sound film 104, so that sound holes are omitted, which is equivalent to that sound is directly emitted from the surface of the frame 301, and thus the design can increase sound emitting area and improve sound quality.
Alternatively, the installation process of the sound processing apparatus 1 on the electronic device may include: the slot body 101 is installed inside the electronic device (as shown in fig. 7), the metal sheet 105 is flatly attached to the bottom of the slot body 101 (as shown in fig. 8), the permanent magnet 102 is flatly attached to the metal sheet 105, the first protrusion 1021 on the permanent magnet 102 is back to the metal sheet 105 (as shown in fig. 9), the elastic air gap pad 103 is laid on the permanent magnet 102, the second protrusion 1031 on the elastic air gap pad 103 faces the permanent magnet 102 (as shown in fig. 10), the electromagnetic induction lead 1042 is attached to the diaphragm 1041 to form the sound membrane 104 (as shown in fig. 4), the side of the sound membrane 104, to which the electromagnetic induction lead 1042 is attached, faces downwards, and is flatly attached to the installation hole 2 on the frame 301 of the device housing 3 (as shown in fig. 11).
Alternatively, the tank 101 in the sound processing apparatus 1 may be a structure independent from the electronic device, and at this time, the tank may be fixedly connected to the middle frame of the electronic device by using a welding technique (e.g., ultrasonic welding) or a bonding technique (e.g., glue bonding). The tank 101 in the sound processing apparatus 1 may also be directly injection-molded on the device housing 3 of the electronic device by using an injection molding technique, i.e., integrally molded with the device housing 3. In particular, the method may be selected according to actual requirements, and the embodiment of the present invention does not limit this.
In summary, in the embodiment of the present invention, the slot 101 in the sound processing apparatus 1 can be used as a carrier of structures such as the permanent magnet 102 and the elastic air gap pad 103. The interaction between the permanent magnet 102 and the sound diaphragm 104 drives the sound diaphragm 104 to vibrate so as to make the sound diaphragm 104 sound. The elastic air gap pad 103 arranged between the permanent magnet 102 and the sound film 104 can attenuate high-frequency signals, highlight middle and low-frequency signals and facilitate the user to hear sound. In addition, the attenuation of the high-frequency signals can reduce the probability of generating the burr signals, reduce distortion and improve the tone quality. Furthermore, under the damping action of the elastic air gap pad 103 on the reflection of the sound wave, the occurrence of echo can be reduced, and the sound quality is improved. In addition, the sound processing device 1 has the advantages of simple and practical structure, easy manufacture, low technical requirement threshold and convenient production.
