Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to a receiver and a terminal. Background Art

[0002] With the popularization of mobile terminals and the rapid development of electronic technology, communication terminal equipment (such as mobile phones), mobile computers, tablet computers and other devices are becoming more and more important in people's lives. Vision is the most important channel for humans to obtain information. When interacting with people and machines on various terminals, intuitive operation is an important way to improve user experience. A larger screen-to-body ratio can bring a sense of technology and fashion to the product. The continuous pursuit of a larger screen-to-body ratio is a major trend in the development of communication terminal equipment.

[0003] A receiver is an electroacoustic device that converts audio signals into sound signals. It is widely used in communication terminal devices such as mobile phones, fixed phones and hearing aids. The receiver usually refers to a dynamic receiver. Its working principle is: the changing audio signal is fed into the voice coil, which is placed in the magnetic gap of a permanent magnet magnetic circuit. The current flows through the voice coil to generate a driving force, which drives the diaphragm to vibrate back and forth and radiate sound waves outward. At present, a sound hole is generally designed just above the diaphragm of the receiver.

[0004] Figure 1 FIG. 1 is a schematic diagram of the position of a receiver in a mobile phone in the prior art. Figure 1 As shown, the front side of the mobile phone shell 2 is provided with a front sound outlet 4 of the mobile phone, a receiver 1 and a sound outlet of the receiver (with Figure 1 The positions corresponding to the front sound holes 4 of the mobile phone are all arranged on the front of the mobile phone (i.e. the screen side), so part of the screen 3 position will be occupied, making it impossible for the mobile phone to truly achieve a full-screen effect; at the same time, when in use, the amount of sound leakage depends on the airtightness of the user's auricle and the mobile phone.

[0005] In order to pursue a larger screen-to-body ratio, the sound outlet of the receiver in some mobile phones is connected to the front of the screen through a sound duct to save screen space. For example, the sound outlet of the receiver is connected to the outlet of the earphone, or the receiver is connected to the corner of the screen through a longer pipe. However, this method has many limitations. First, because the receiver emits sound through a longer sound duct, there will be a large loss in the high-frequency part. Secondly, because the sound outlet is close to the edge of the screen, or on the side of the screen, the user's ear can not form a sealed cavity with the mobile phone during a call, which is different from the traditional mobile phone. Figure 1 In the solution shown, the sound leakage phenomenon is more serious, which reduces the privacy of calls and affects the user experience. Similarly, the size of the sound leakage depends on the airtightness of the user's ear and the mobile phone. Summary of the invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problem of sound leakage in the prior art, thereby providing a receiver and a terminal.

[0007] According to the first aspect, the present invention provides a receiver, wherein a diaphragm is provided inside the receiver, and the diaphragm divides the receiver into a magnetic circuit cavity and a front cavity, a first sound output area is provided on the magnetic circuit cavity, and a first damping material is provided on the first sound output area; a second sound output area is provided on the front cavity, and a second damping material is provided on the second sound output area; the first sound output area and the second sound output area are connected to both sides of the diaphragm.

[0008] In combination with the first aspect, in a first implementation of the first aspect, the damping of the second damping material is different from the damping of the first damping material, so that the receiver can achieve directivity control of sound wave radiation.

[0009] In combination with the first aspect, in the second embodiment of the first aspect, the first sound output area is arranged on the side wall of the magnetic circuit cavity and the second sound output area is arranged on the wall surface of the front cavity opposite to the diaphragm; or the first sound output area is arranged on the wall surface of the magnetic circuit cavity opposite to the diaphragm and the second sound output area is arranged on the side wall of the front cavity.

[0010] In combination with the first aspect, in a third embodiment of the first aspect, at least one sound outlet hole is provided in the first sound outlet area and / or the second sound outlet area.

[0011] In combination with the first aspect, the first embodiment of the first aspect, the second embodiment of the first aspect and the third embodiment of the first aspect, in the fourth embodiment of the first aspect, the receiver also includes a shell, a cover and a basin; the diaphragm is located on the top of the shell, and forms a magnetic circuit cavity with the shell and the basin; the cover is arranged on the shell, and forms a front cavity with the diaphragm.

[0012] In combination with the fourth embodiment of the first aspect, in the fifth embodiment of the first aspect, the magnetic circuit cavity also includes a voice coil, a washer and a magnet; the voice coil is arranged on the diaphragm, the magnet is arranged on the basin frame, and the washer is arranged on the magnet.

[0013] In combination with the fifth embodiment of the first aspect, in the sixth embodiment of the first aspect, when the basin frame is circumferentially nested on the shell, the first sound output area is arranged on the magnetic circuit assembly composed of the washer, the magnet and the basin frame.

[0014] In combination with the fourth embodiment of the first aspect, in the seventh embodiment of the first aspect, when the shell is covered on the basin frame, the first sound output area is arranged on the side wall of the shell, and a third sound output hole is provided on the basin frame, and the first sound output area is connected to the diaphragm through the third sound output hole.

[0015] In combination with the fourth embodiment of the first aspect, in the eighth embodiment of the first aspect, the second sound output area is arranged on the cover body.

[0016] In order to solve the problem of sound leakage of the terminal, according to the second aspect, an embodiment of the present invention provides a terminal, including the receiver described in the first aspect or any embodiment of the first aspect, and the first sound output area and the second sound output area are both arranged corresponding to the sound output hole of the terminal.

[0017] In order to solve the problem that the receiver outlet occupies the screen space of the mobile phone, in combination with the second aspect, in the first implementation of the second aspect, when the terminal is a mobile phone, one sound output area of ​​the receiver is set to correspond to the sound output hole on the top of the mobile phone, and the other sound output area of ​​the receiver is set to correspond to the sound output hole on the back of the mobile phone.

[0018] In combination with the first embodiment of the second aspect, in the second embodiment of the second aspect, the damping of the damping material on the sound output area of ​​the receiver corresponding to the sound output hole on the back of the mobile phone is greater than the damping of the damping material on the sound output area of ​​the receiver corresponding to the sound output hole on the top of the mobile phone.

[0019] In combination with the second aspect, the first implementation of the second aspect, and the second implementation of the second aspect, in a third implementation of the second aspect, the receiver is located on the non-screen side of the terminal.

[0020] In combination with the second aspect, the first embodiment of the second aspect, and the second embodiment of the second aspect, in a fourth embodiment of the first aspect, the first sound output area and the second sound output area are directly connected to the sound output hole of the terminal.

[0021] The technical solution of the present invention has the following advantages:

[0022] 1. The receiver provided by the present invention has a diaphragm inside the receiver, and the diaphragm divides the receiver into a magnetic circuit cavity and a front cavity; a first sound outlet area is provided on the magnetic circuit cavity, the first sound outlet area is connected to the diaphragm, and a first damping material is provided on the first sound outlet area; a second sound outlet area is provided on the front cavity, the second sound outlet area is connected to the diaphragm, and a second damping material is provided on the second sound outlet area. That is, the first sound outlet area and the second sound outlet area are respectively connected to the two sides of the diaphragm, thereby, coherent sound waves can be obtained at the first sound outlet area and the second sound outlet area; at the same time, since the first damping material is provided on the first sound outlet area and the second damping material is provided on the second sound outlet area, the directivity control of the sound wave radiation can be achieved by adjusting the damping of the first damping material and the second damping material. At present, the sound waves generated by the receiver are radiated to the whole space in a non-directional manner. When in use, the size of the sound leakage depends on the degree of sealing between the user's auricle and the mobile phone. The receiver provided by the present invention solves the problem of sound leakage by controlling the directivity of the sound wave radiation.

[0023] 2. In the terminal provided by the present invention, the first sound output area and the second sound output area in the receiver both correspond to the sound output hole of the terminal, thereby realizing the directivity control of sound wave radiation at the sound output hole of the terminal and solving the problem of sound leakage.

[0024] 3. In the terminal provided by the present invention, when the terminal is a mobile phone, one sound output area of ​​the receiver corresponds to the sound output hole on the top of the mobile phone, and the other sound output area of ​​the receiver corresponds to the sound output hole on the back of the mobile phone. Therefore, the receiver can be installed on the non-screen side of the mobile phone, and the receiver will not occupy the mobile phone screen. At the same time, the directionality of sound wave radiation can be controlled at the sound output hole of the terminal, which solves the call problem of full-screen mobile phones. At the same time, this solution does not significantly increase the cost or difficulty of mobile phone manufacturing.

[0025] 4. In the terminal provided by the present invention, when the terminal is a mobile phone, the damping of the damping material on the sound output area of ​​the receiver corresponding to the sound output hole on the back of the mobile phone is greater than the damping of the damping material on the sound output area of ​​the receiver corresponding to the sound output hole on the top of the mobile phone. Thus, the damping of the first damping material and the damping of the second damping material can be adjusted to form a cardioid directivity or a supercardioid directivity, and the cardioid or supercardioid points to the line connecting the two sound output areas and toward the direction of the auricle. That is, the backward sound is eliminated directionally, and the energy is concentrated into the auricle. At the same time, because the unidirectional sound source has a "close-talking effect", the sound energy decays faster, and it can also prevent other people in the distance from hearing the sound of the receiver, making it more private.

[0026] 5. In the terminal provided by the embodiment of the present invention, the first sound output area and the second sound output area in the receiver are directly connected to the sound output hole of the terminal, which can avoid the problem of large loss of the high-frequency part caused by the use of a sound conduit for connection.

[0037] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] Example 1

[0042] like Figure 2 A specific embodiment of the receiver shown in FIG. 1 is a receiver with a diaphragm 15 disposed inside the receiver. The diaphragm 15 divides the receiver into a magnetic circuit cavity 11 and a front cavity 12. A first sound outlet area (at Figure 2 The first sound outlet area is provided with a first damping material 13; the front cavity 12 is provided with a second sound outlet area (in Figure 2 (not shown), a second damping material 14 is provided on the second sound output area; and the first sound output area and the second sound output area are connected to both sides of the diaphragm 15.

[0043] It should be noted that the first sound output area and the second sound output area mentioned above only represent different names of the two sound output areas, and do not mean that the sizes, shapes and other features of the two sound output areas are also different. The sizes, shapes and other features of the two sound output areas can be the same or different.

[0044] The first sound output area and / or the second sound output area are provided with at least one sound output hole, for example, it can be one sound output hole, or it can be a mesh hole composed of two or more small holes. Similarly, the first damping material 13 and the second damping material 14 only represent that there are two damping materials in the first sound output area and the second sound output area respectively, and do not mean that the materials and other properties of the two damping materials are different. For example, the damping material can be a material with acoustic impedance such as foam, mesh, non-woven fabric, and a combination thereof. When the first damping material 13 is foam, the second damping material 14 can be made of mesh, non-woven fabric, and other materials, and can also be foam.

[0045] As a possible implementation, the damping of the second damping material 14 is different from the damping of the first damping material 13 , that is, the damping of the second damping material 14 is greater than the damping of the first damping material 13 , or the damping of the first damping material 13 is greater than the damping of the second damping material 14 .

[0046] As a possible implementation, the first sound output area is arranged on the side wall of the magnetic circuit cavity 11 and the second sound output area is arranged on the wall surface of the front cavity 12 opposite to the diaphragm 15; or the first sound output area is arranged on the wall surface of the magnetic circuit cavity 11 opposite to the diaphragm 15 and the second sound output area is arranged on the side wall of the front cavity 12. For example, Figure 2 The receiver shown is of long rectangular design. In this rectangular structure, the first sound output area is arranged parallel to the diaphragm 15, that is, it is arranged on the wall surface of the magnetic circuit cavity 11 opposite to the diaphragm 15; the second sound output area is arranged perpendicular to the diaphragm 15, that is, the second sound output area is arranged on the side wall of the front cavity 12. Of course, the first sound output area can also be arranged perpendicular to the diaphragm 15 and the second sound output area can be arranged parallel to the diaphragm 15. It should be noted that the above only stipulates the setting positions of the first sound output area and the second sound output area, and does not limit the shapes of the first sound output area and the second sound output area. The first sound output area and the second sound output area can be round holes or square holes; they can be straight holes or oblique holes.

[0047] In the receiver provided in the embodiment of the present invention, a diaphragm 15 is provided inside the receiver, and the diaphragm 15 divides the receiver into a magnetic circuit cavity 11 and a front cavity 12; a first sound outlet area is provided on the magnetic circuit cavity 11, the first sound outlet area is connected to the diaphragm 15, and a damping material is provided on the first sound outlet area; a second sound outlet area is provided on the front cavity 12, the second sound outlet area is connected to the diaphragm 15, and a damping material is provided on the second sound outlet area, and the first sound outlet area and the second sound outlet area are respectively connected to both sides of the diaphragm 15, thereby, coherent sound waves can be obtained at the first sound outlet area and the second sound outlet area, and since the sound path difference in different directions in space when the two sound outlet areas radiate is different, directivity can be formed in different directions in space. At the same time, since a first damping material 13 is provided on the first sound outlet area and a second damping material 14 is provided on the second sound outlet area, the directivity control of sound wave radiation can be achieved by adjusting the damping of the first damping material 13 and the second damping material 14.

[0049] Figure 3 A specific structural diagram of a receiver is shown in FIG. Figure 3 As shown, the receiver includes a housing 17 , a cover 16 , a basket 18 , a voice coil 111 , a washer 112 and a magnet 113 .

[0050] like Figure 3 As shown, the basket 18 is circumferentially nested in the shell 17, the diaphragm 15 is located on the top of the shell 17, and forms a magnetic circuit cavity with the shell 17 and the basket 18; the magnetic circuit cavity also includes a voice coil 111, a washer 112 and a magnet 113; the voice coil 111 is arranged on the diaphragm 15, the magnet 113 is arranged on the basket 18, the washer 112 is arranged on the magnet 113, the first sound output area 19 is arranged on the magnetic circuit assembly composed of the washer 112, the magnet 113 and the basket 18 (that is, the first sound output area 19 is arranged on the basket 18, and the first sound output area 19 passes through the basket 18, the magnet 113 and the washer 112), and a first damping material 13 is also provided on the first sound output area 19.

[0051] The cover 16 is disposed on the housing 17 and forms a front cavity with the diaphragm 15. The second sound output area 20 is disposed on the side wall of the cover 16. Figure 3 A second damping material 14 is also provided on the upper surface (not shown).

[0052] As a possible implementation manner, the damping of the second damping material 14 is different from the damping of the first damping material 13 .

[0053] exist Figure 3In the figure, the direction of the receiver diaphragm 15 toward the cover 16 is called direction A, and the direction of the receiver diaphragm 15 toward the magnetic circuit is called direction B. The sound in direction A is connected to the second sound output area, and the sound in direction B is connected to the first sound output area 19.

[0054] In Example 2 of the present invention, the magnetic circuit assembly can be a single magnet design as shown in the figure, or it can be a different magnetic circuit system such as a double magnet, a triple magnet, a five magnet, etc., which does not affect the final effect of this embodiment.

[0055] Example 3

[0056] Figure 4 is a schematic diagram of another specific structure of a receiver, such as Figure 4 As shown, the receiver includes a housing 17 , a cover 16 , a basket 18 , a voice coil 111 , a washer 112 and a magnet 113 .

[0057] like Figure 6 As shown, the housing 17 covers the basin frame 18, the diaphragm 15 is located on the top of the housing 17, and forms a magnetic circuit cavity with the housing 17 and the basin frame 18; the magnetic circuit cavity includes a voice coil 111, a washer 112 and a magnet 113; the voice coil 111 is arranged on the diaphragm 15, the magnet 113 is arranged on the basin frame 18, and the washer 112 is arranged on the magnet 113. The first sound output area (at Figure 4 The first sound emitting area is connected to the diaphragm 15 through the third sound emitting hole 21. The sound waves generated by the diaphragm 15 are transmitted to the first sound emitting area 19 through the third sound emitting hole 21. The first damping material 13 is also provided on the first sound emitting area.

[0058] The cover 16 is disposed on the shell 17 and forms a front cavity with the diaphragm 15 . The second sound output area 20 is disposed on the cover 16 and directly opposite to the diaphragm 15 . A second damping material 14 is also disposed on the second sound output area 20 .

[0059] As a possible implementation manner, the damping of the second damping material 14 is different from the damping of the first damping material 13 .

[0060] exist Figure 6 In the figure, the direction of the receiver diaphragm 15 toward the cover 16 is called direction A, and the direction of the receiver diaphragm 15 toward the magnetic circuit is called direction B. The sound in direction A is connected to the second sound output area 20, and the sound in direction B is connected to the first sound output area.

[0061] In Example 3 of the present invention, the magnetic circuit assembly can be a single magnet design as shown in the figure, or it can be a different magnetic circuit system such as a double magnet, a triple magnet, a five magnet, etc., which does not affect the final effect of this embodiment.

[0062] Example 4

[0063] An embodiment of the present invention provides a terminal with a receiver installed, wherein the first sound output area and the second sound output area on the receiver are both arranged corresponding to the sound output hole of the terminal, thereby realizing the directivity control of the sound wave radiation in the terminal. It should be noted that when the terminal and the user are not in the same position, the directivity control can be toward one end of the user, for example, when the terminal is at position A and the user is at position B, the directivity control can be understood as pointing from position A to position B; when the terminal and the user are in the same position, the directivity control can also be understood as the direction toward the user's ear, for example, when the terminal is a mobile phone, the directivity control is the direction of the user's ear.

[0064] Figure 4 for Figure 2 The receiver is shown in the figure below. Figure 4 In the embodiment, the first sound output area of ​​the receiver is set corresponding to the sound output hole 5 on the top of the mobile phone, and the second sound output area of ​​the receiver is set corresponding to the sound output hole 6 on the back of the mobile phone; of course, the second sound output area of ​​the receiver can also be set corresponding to the sound output hole 5 on the top of the mobile phone, and the first sound output area of ​​the receiver can be set corresponding to the sound output hole 6 on the back of the mobile phone. Figure 3 As shown, the receiver can be installed near the top and back of the mobile phone, without occupying any area of ​​the front screen area of ​​the mobile phone, so that the mobile phone can achieve a full screen. At the same time, the sound output area of ​​the receiver can be directly connected to the sound output hole on the mobile phone case (that is, the top sound output hole 5 and the back sound output hole of the mobile phone), without additional sound conduit occupying the internal space of the mobile phone, thus overcoming the high-frequency loss problem caused by the sound conduit.

[0065] In order to better control the directionality of sound wave radiation, the damping of the damping material on the sound outlet area of ​​the receiver corresponding to the sound outlet hole on the back of the mobile phone needs to be greater than the damping of the damping material on the sound outlet area of ​​the receiver corresponding to the sound outlet hole on the top of the mobile phone. Figure 3 and Figure 4 The receiver is used as an example for detailed description.

[0066] when Figure 3 When the second sound output area of ​​the receiver shown is set corresponding to the top sound output hole 5 of the mobile phone and the first sound output area 19 is set corresponding to the back sound output hole 6 of the mobile phone, the damping of the first damping material 13 needs to be greater than the damping of the second damping material 14.

[0067] when Figure 4When the first sound output area 19 of the receiver shown is set corresponding to the top sound output hole 5 of the mobile phone and the second sound output area is set corresponding to the back sound output hole 6 of the mobile phone, the damping of the second damping material 14 needs to be greater than the damping of the first damping material 13.

[0068] Thus, the amplitude of the sound waves radiated from the sound outlet hole on the back of the mobile phone can be made smaller than that radiated from the sound outlet hole on the top of the mobile phone. The damping of the first damping material 13 and the damping of the second damping material 14 can be adjusted according to the acoustic impedance of the front and rear cavities, such as Figure 6 As shown, a cardioid or supercardioid directivity can be formed, and the cardioid or supercardioid directivity is directed to the line connecting the two sound output areas and toward the auricle. That is, the sound directed backward is eliminated and the energy is concentrated into the auricle. At the same time, since the unidirectional sound source has a "close-talking effect", the sound energy decays faster, and other people in the distance can be prevented from hearing the sound of the receiver, making it more private. At the same time, this solution does not significantly increase the cost or difficulty of mobile phone manufacturing.

[0069] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
