Description

Electronic device including a speaker module

[0001] The present disclosure relates to an electronic device, and more particularly, to an electronic device including a speaker module.

[0002] Electronic devices are becoming increasingly thinner. This trend is also significantly reducing the thickness of internal components, such as speaker modules.

[0003] As the thickness of speaker modules in electronic devices decreases, their durability is significantly weakened. Consequently, if the electronic device is dropped and subjected to external impact, the components that make up the speaker module are more likely to separate.

[0004] Detachment of the metal mesh provides a path for various foreign substances, such as pieces of sound-absorbing material, to enter the speaker module, which can ultimately result in a deterioration in the overall sound quality of the electronic device.

[0005] In one embodiment, an electronic device may include a housing and a speaker module disposed inside the housing. The speaker module may include a diaphragm, a voice coil coupled to a lower surface of the diaphragm, a magnet interacting with the voice coil to vibrate the diaphragm, a frame surrounding an outer side of the magnet, a yoke plate disposed on a lower side of the magnet and including a bending portion having at least one opening, and a mesh cover having a first end fixed between the bending portion of the yoke plate and the frame and a second end attached to an upper surface of the yoke plate so as to cover the at least one opening on an inner side of the bending portion. The mesh cover may be made of a flexible, air-permeable material.

[0006] The above and / or other aspects of the present disclosure will become more apparent by describing embodiments of the present disclosure with reference to the accompanying drawings.

[0022] It should be understood that the various embodiments and terms used in this document are not intended to limit the technical features described in this document to specific embodiments, but rather to include various modifications, equivalents, or substitutes of the embodiments.

[0023] In connection with the description of the drawings, similar reference numerals may be used for similar or related components.

[0024] The singular form of a noun corresponding to an item may include one or more of said item, unless the context clearly dictates otherwise. For example, as used herein, "a," "an," "the," and "at least one" do not indicate a limitation on quantity and may include both the singular and the plural unless the context clearly dictates otherwise. Accordingly, a reference to a "the" element in a claim following a reference to an "an" element includes both one and multiple elements. For example, "an element" has the same meaning as "at least one element," unless the context clearly dictates otherwise.

[0025] In this document, each of the phrases "A or B", "at least one of A and B", "at least one of A or B", "A, B, or C", "at least one of A, B, and C", and "at least one of A, B, or C" may include any one of the items listed together in that phrase, or all possible combinations thereof.

[0026] The term "and / or" includes any combination of a plurality of related described elements or any one of a plurality of related described elements.

[0027] Terms such as "first," "second," or "first" or "second" may be used simply to distinguish one component from another and do not qualify the components in any other respect (e.g., importance or order).

[0028] When a component (e.g., a first component) is referred to as being "coupled" or "connected" to another component (e.g., a second component), with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.

[0029] The terms "exists," "includes," or "has" are intended to specify the presence of a feature, number, step, operation, component, part, or combination thereof described in this document, but do not preclude the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0030] When a component is said to be “connected,” “coupled,” “supported,” or “in contact with” another component, this includes not only cases where the components are directly connected, coupled, supported, or in contact, but also cases where the components are indirectly connected, coupled, supported, or in contact through a third component.

[0031] When we say that an element is "on" another element, this includes not only cases where the element is adjacent to the other element, but also cases where another element exists between the two elements. For example, when an element is said to be "on" another element, or in relation to another element, that element may be directly on the other element, or there may be intervening elements between them. Conversely, when an element is said to be "directly" on another element, there are no intervening elements.

[0032] As used herein, "about" or "approximately" means within an acceptable range of deviation from the stated value, determined by one of ordinary skill in the art, taking into account the errors associated with the measurement and measurement of the particular quantity (i.e., limitations of the measurement system). For example, "about" can mean within one or more standard deviations, or within ± 30%, 20%, 10%, or 5% of the stated value.

[0033] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

[0034] Terms defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present disclosure, and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0035] Embodiments are described herein with reference to cross-sectional drawings, which are schematic illustrations of idealized embodiments. Therefore, variations from the shapes of the drawings, for example, as a result of manufacturing techniques and / or tolerances, should be expected. Accordingly, the embodiments described herein should not be construed as being limited to the specific shapes of specific regions illustrated herein, and include, for example, shape variations resulting from manufacturing. For example, regions illustrated or described as flat may generally have rough or non-linear features. Furthermore, portions with sharp angles may be rounded. Therefore, the regions illustrated in the drawings are schematic in nature, and their shapes are not intended to describe the precise shapes of the regions and are not intended to limit the scope of the claims. Hereinafter, an electronic device (100) according to various embodiments will be described in detail with reference to the drawings.

For example, the processor (110) may be implemented as multiple cores (or at least one core circuit), multiple chips, or multiple chipsets. For example, the processor (110) may include one or more processing circuits. For example, the processor (110) may include one or more processing circuits configured to individually and / or collectively perform various functions of the present disclosure. As a non-limiting example, at least a portion of the processor (110) may be included in a first chip of the electronic device (100), and at least another portion of the processor (110) may be included in a second chip of the electronic device (100) that is different from the first chip of the electronic device (100).

[0041] For example, the processor (110) may include a central processing unit (CPU) (111), a graphics processing unit (GPU) (112), a neural processing unit (NPU) (113), an image signal processor (ISP) (114), a display controller (115), a memory controller (116), a storage controller (117), a communication processor (CP) (118), and / or a sensor interface (119). These components of the processor (110) are merely exemplary. For example, the processor (110) may further include other components. For example, some components of the processor (110) may be omitted from the processor (110). For example, some components of the processor (110) may be included as separate components of the electronic device (100) outside the processor (110). For example, some components of the processor (110) (e.g., memory controller (116)) may be included within other components (e.g., at least a portion of memory (120), an interface (e.g., available for connection to at least one component of the electronic device (100)), a display (140) and / or an image sensor (150)).

[0042] The processor (110) may cause other components of the electronic device (100) to perform various operations by executing instructions stored in the memory (120). The CPU (111) (or central processing circuit) may be configured to control components of the processor (110) based on the execution of instructions stored in the memory (120) (e.g., volatile memory (121) and / or non-volatile memory (122)). The GPU (112) (or graphics processing circuit) may be configured to execute parallel operations (e.g., rendering). The NPU (113) (or neural processing circuit, or artificial intelligence (AI) chip) may be configured to execute operations for an artificial intelligence model (e.g., convolution computation). The ISP (114) (or image signal processing circuit) may be configured to process a raw image acquired through the image sensor (150) into a format suitable for a component within the electronic device (100) or a component of the processor (110). The display controller (115) (or display control circuit, or display processing unit (DPU)) may be configured to process an image acquired from the CPU (111), the GPU (112), the ISP (114), or the memory (120) (e.g., the volatile memory (121)) into a format suitable for the display (140). The memory controller (116) (or memory control circuit) may be configured to control reading data from the volatile memory (121) and writing data to the volatile memory (121).

For example, the communication circuit (160) may include one or more communication circuits. The sensor interface (119) (or sensing data processing circuit, sensor hub) may be configured to process data about the state of the electronic device (100) and / or the state of the surroundings of the electronic device (100), acquired via the sensor (170), into a format suitable for the component of the processor (110).

[0043] The memory (120) may include one or more storage media (or one or more storage devices). For example, the memory (120) may include a memory assembly including one or more storage media. For example, the one or more storage media may include permanent memory (e.g., non-volatile memory (122)) such as a hard drive, flash memory, read-only memory (ROM), semi-permanent memory (e.g., volatile memory (121)) such as random access memory (RAM), any other suitable type of storage (or storage assembly), or any combination thereof. The memory (120) may include cache memory, which is one or more different types of memory used to temporarily store data for a function or feature of the electronic device (100). As a non-limiting example, the cache memory may be included within the processor (110). The memory (120) may be fixedly embedded within the electronic device (100) or incorporated into one or more suitable types of components (e.g., a subscriber identity module (SIM) card and / or a secure digital (SD) card) that may be repeatedly inserted into and removed from the electronic device (100).

[0044] For example, the memory (120) may store one or more software applications, such as an operating system (or system) software application, a firmware software application, a driver software application, a plug-in (e.g., add-in, add-on, and / or applet) software application, and / or any other suitable software applications. For example, the one or more software applications may include instructions executable by the processor (110). For example, the memory (120) may store instructions callable by an application programming interface (API). For example, the memory (120) may store instructions within a library.

[0045] Hereinafter, from FIG. 2, the speaker module (181) of the speaker (180) will be described.

[0046] FIG. 2 is a drawing showing an electronic device (100) having at least one speaker module (181) arranged therein, according to one embodiment.

[0047] Referring to FIG. 2, the electronic device (100) may include a housing (101), a display (140), and at least one speaker module (181).

[0048] The housing (101) can form the exterior of the electronic device (100).

[0049] In FIG. 2, the housing (101) is illustrated only in the form of a smartphone, but is not limited thereto. For example, the housing (101) may take on various forms depending on the type of electronic device (100) (e.g., a laptop (190), smartphones (191) having various form factors (e.g., a bar-type smartphone (191-1), a foldable-type smartphone (191-2), or a sliderable (or rollable) type smartphone (191-3)), a tablet (192), a cellular phone (not shown), and other similar computing devices (not shown)).

[0050] Referring to FIG. 2, according to at least one embodiment, the speaker (180) may include at least one speaker module (181). Accordingly, the processor (110) may include any processing circuit operative to control the performance and operations of at least one speaker module (181).

[0051] For example, the processor (110) can detect the position of the human body and / or the directionality (e.g., landscape mode or portrait mode) of the electronic device (100) from the electronic device (100) through at least one sensor (170). Through this, the processor (110) can control the operations of at least one speaker module (181) according to the position of the human body to optimize the three-dimensional sound effect and improve the sound quality.

[0052] Hereinafter, the configuration and structure of the speaker module (181) will be described with reference to the drawings.

[0053] Fig. 3 is a perspective view showing the assembly of a speaker module (181) according to one embodiment. Fig. 4 is an exploded perspective view of a speaker module (181) according to one embodiment.

[0054] Referring to FIGS. 3 and 4, the speaker module (181) may include a driving unit (210) and a magnetic unit (300). The driving unit (210) includes components necessary to actually drive the speaker module (181). For example, the driving unit (210) may include a vibration plate (211), a frame (220), a suspension (230), and a voice coil (240). The driving unit (210) may serve to convert an electric signal into mechanical motion through the voice coil (240) and the vibration plate (211).

[0055] The voice coil (240) can be coupled at its upper end to the lower side of the diaphragm (211). Accordingly, the voice coil (240) can be placed in the space between the inner magnet (510) and the outer magnet (520) (e.g., see FIG. 7), thereby converting an electric signal into mechanical motion.

[0056] The magnetic field unit (300) includes components necessary for driving the speaker module (181). For example, the magnetic field unit (300) may include an inner magnet (510), an outer magnet (520), and a yoke plate (310). The magnetic field unit (300) may provide a strong and stable magnetic field in the speaker module (181) to enable the driving unit (210) to operate effectively. For example, the inner magnet (510) and the outer magnet (520) may provide the force necessary for the voice coil (240) to move in response to current (e.g., current).

[0057] Referring to FIG. 4, the inner magnet (510) may be positioned at the center of the upper surface of the yoke plate (310) and may have a rectangular parallelepiped shape. The outer magnet (520) may be positioned at the upper surface of the yoke plate (310) and may be positioned to surround the inner magnet (510) at a certain distance from the outer surface of the inner magnet (510).

[0058] The inner magnet (510) and the outer magnet (520) can be placed adjacent to the voice coil (240) to vibrate the diaphragm (211). The inner magnet (510) and the outer magnet (520) can interact with the magnetic field of the voice coil (240).

[0059] The suspension (230) may be in the form of surrounding the outer surface of the diaphragm (211). The suspension (230) as a suspension member (or support member) may flexibly support the diaphragm (211). The suspension (230) may be made of a flexible material so that the diaphragm (211) can move up and down along the thickness of the speaker module (181).

[0060] The suspension (230) may be made of various flexible materials (e.g., rubber). The suspension (230) may stabilize the movement of the diaphragm (211), absorb vibrations, and help return the diaphragm (211) to its original position within the speaker module (181).

[0061] The frame (220) may be formed to surround the outer surface of the diaphragm (211) and the suspension (230). The frame (220) may be coupled to the outer surface of the suspension (230) along the inner surface. The frame (220) may indirectly support the diaphragm (211) through the suspension (230). The frame (220) may be made of a synthetic resin or a metal material.

[0062] The conductor (221) may be disposed on the lower side of the frame (220) (e.g., in the -direction of the Z-axis in FIG. 4, i.e., the direction along the thickness direction indicated by the Z-axis). For example, the conductor (221) may be attached to the lower side of the frame (220) by an adhesive. The conductor (221) may be formed of a flexible printed circuit board (FPCB) and may have electrical conductivity. The conductor (221) may apply current to the voice coil (240) so that the diaphragm (211) may be driven. However, the present invention is not limited thereto, and the conductor (221) may be disposed in another configuration (e.g., the housing (310)) to apply current to the voice coil (240).

[0063] The yoke plate (310) may be arranged on the lower side of the inner magnet (510) and the outer magnet (520). The yoke plate (310) may include a bending part (320). The bending part (320) may be in a form that extends laterally or flatly from both sides of the yoke plate (310) toward the frame (220). The bending parts (320) provided on both sides of the yoke plate (310) may be formed symmetrically with each other and may move along the Y-axis direction. Hereinafter, the bending part (320) provided on the left side of the yoke plate (310) in FIG. 4 will be described as a reference. (For example, the left side of FIG. 4)

[0064] Referring to FIGS. 3 and 4, according to one embodiment, the bending portion (320) may include a first support portion (321) of the first side portion, a second support portion (322) of the second side portion, and a third support portion (323) of the third side portion. The first support portion (321) and the second support portion (322) may be spaced apart from each other. That is, they may be spaced apart from each other along the periphery of the yoke plate (310). The third support portion (323) may be positioned between the first support portion (321) and the second support portion (322). The space between the first support portion (321) and the third support portion (323) and the space between the second support portion (322) and the third support portion (323) may be substantially the same, but is not limited thereto.

[0065] The first support portion (321) and the second support portion (322) may extend at an angle of approximately 45 degrees (e.g., angle α in FIG. 4) toward the center of the speaker module (181) based on a virtual line extended from the side portion of the speaker module (181). The third support portion (323) may be configured at an angle parallel to the side portion of the speaker module (181) (e.g., in the X-axis direction in FIG. 4). The height of the third support portion (323) (e.g., in the Z-axis direction in FIG. 4) may be substantially the same as the heights of the first support portion (321) and the second support portion (322) based on the yoke plate (310).

[0066] The bending portion (320) may have a first opening (320a) and a second opening (320b) defined by various support portions spaced apart from each other. However, the first opening (320a) and the second opening (320b) of the bending portion (320) illustrated in FIG. 3 are merely examples and are not limited thereto.

[0067] When the frame (220) coupled to the yoke plate (310) is considered as a kind of speaker module housing, the opening (320) defined by the yoke plate (310) exposes the interior of the speaker housing to the exterior of the speaker module (181), so that the interior and the exterior can communicate with each other (e.g., fluid, sound, etc.).

[0068] The mesh cover (400) may be placed on the inner side of the first opening (320a) and the second opening (320b) provided in the folded portion (320). Referring to FIG. 3, the mesh cover (400) may be exposed to the outside through a gap (e.g., the first opening (320A) and the second opening (320B)) of the yoke plate (310). However, since the mesh cover (400) effectively separates the inside and the outside of the speaker housing, it may prevent foreign substances from passing into the inside of the speaker module (181) while allowing sound to be transmitted from the inside of the speaker module (181) to the outside of the speaker module (181).

[0069] Fig. 6 is a perspective view showing a bent portion (320) of a yoke plate (310) according to one embodiment. Referring to Fig. 6, when the third support portion (323) is omitted from the bent portion (320), one opening (e.g., see 320c of Fig. 5) of the bent portion (320) may be provided.

[0070] Figure 7 is an enlarged view showing a bending portion (320) of a yoke plate (310) according to one embodiment.

[0071] Referring to FIG. 7, the bending portion (320) may include a plurality of third support portions (323) including two third support portions (323a, 323b), and three openings (e.g., see 320a, 320b, and 320c of FIG. 6) may be provided in the bent portion between adjacent support portions. For example, if there are n third support portions (323) between the first support portion (321) and the second support portion (322), the bending portion (320) may be provided with n+1 openings (where n is a natural number).

[0072] Referring to Fig. 4, the support portion may have an inner surface in the Y-axis direction and an outer surface in the -Y-axis direction.

[0073] The front of a mesh cover (e.g., mesh cover (400) of FIG. 4) can be attached to the inner side of the two third supports (323a, 323b) using an adhesive. Accordingly, the possibility of the mesh cover (400) being detached from the bending portion (320) due to impact can be reduced.

[0074] Various supports of the yoke plate (310) can define side walls of the yoke plate (310) extending from the base plate. The side walls of the yoke plate (310) can overlap side walls (or ends) of the frame (220). For example, referring to FIGS. 4, 6, and 7, at least the first supports (321) can provide side walls of the yoke plate (310) spaced apart from each other along the periphery of the base plate to define an opening or a gap therebetween through which the mesh cover (40) can be exposed to the outside of the assembled speaker module (181). A third support (323), provided singly or in plurality, can provide an additional side wall portion defining an opening.

[0075] According to one embodiment, the speaker module (181) may include a mesh cover (400). The mesh cover (400) may emit rear sound of the speaker module (181) to the outside of the speaker module (181) through a first opening (320a) and a second opening (320b) provided in the bending portion (320). Here, the 'rear sound' may be a sound output from the lower side of the diaphragm (211) and emitted through the first opening (320a) and the second opening (320b) toward the outside of the speaker module (181). The sound emitted in the upper direction of the diaphragm (211) may be referred to as a 'front sound'.

[0076] In addition, the mesh cover (400) can block foreign substances (e.g., pieces of sound-absorbing material existing around the speaker module (181)) from flowing into the inside of the speaker module (181) through the first opening (320a) and the second opening (320b) from the outside of the speaker module (181).

[0077] The mesh cover (400) may be positioned on the inside of the speaker module (181). For example, the mesh cover (400) may be attached to the inside surface of the folded portion (320) or one or more side walls (e.g., support portions). The mesh cover (400) may be firmly attached as the area adhered to the folded portion (320) increases as the number of third support portions (323) of the folded portion (320) increases (e.g., see FIG. 6).

[0078] The first opening (320a) and the second opening (320b) of the bending portion (320) may have a rectangular shape. The shapes of the first opening (320a) and the second opening (320b) are not limited to a rectangular shape, and may have various shapes such as a circle or an oval. These shapes may be defined in a plan view (e.g., a view defining the plane where the X-axis direction and the Y-axis direction intersect as the XY plane) and / or a cross-sectional view (e.g., a view defining the plane where the Z-axis direction and the X-axis direction intersect as the XZ plane).

[0079] In addition, the first opening (320a) and the second opening (320b) may have a slot shape. For example, referring to the plan view of FIG. 5, the first opening (320a) having a slot shape may be formed to face the side surface of the support portion (321, 323) at a set angle to the left with respect to the Y-axis, and may be formed to face the side surface of the support portion (321, 323) that is inclined at a set angle to the left with respect to the Y-axis. The second opening (320b) having a slot shape may be formed to face the right surface of the support portion (322, 323) at a set angle to the right. In this case, the first opening (320a) and the second opening (320b) may be arranged symmetrically with respect to each other with respect to the X-axis direction along the length of the third support portion (323) or the bent portion (320). In this way, when the first opening (320a) and the second opening (320b) have a slot shape, the speaker module (181) can finely adjust the direction of rear sound, improve sound quality in a specific frequency band, and optimize the acoustic design.

[0080] Referring to FIGS. 3 and 4, the mesh cover (400) may be placed on the inner side of the speaker module (181). For example, the mesh cover (400) may be placed on the upper side of the base plate of the yoke plate (310) and the inner side of the folded portion (320) of the side surface of the yoke plate (310). The central portion (e.g., 400c in FIG. 8) of the mesh cover (400) covering the first opening (320a) and the second opening (320b) may be placed approximately perpendicularly (e.g., in the Z-axis in FIG. 4) to the upper surface of the base plate of the yoke plate (310). The upper portion of the mesh cover (430) may be folded from the central portion of the mesh cover (400) to the outer side of the speaker module (181) (e.g., in the - direction of the Y-axis in FIG. 4). The lower part of the mesh cover (400) may be folded from the central part of the mesh cover (400) (e.g., 400c in FIG. 8) toward the inside of the speaker module (181) (e.g., in the + direction of the Y-axis in FIG. 4). The upper part of the mesh cover (400) may be referred to as a first end (e.g., 400a in FIG. 8). The lower part of the mesh cover (400) may be referred to as a second end (e.g., 400b in FIG. 8) opposite to the first end portion (400a). The mesh cover (400) is not limited thereto, and a cross-section may include a 'Z' shape.

[0081] The first end (400a) of the mesh cover (400) may be positioned between the conductor (221) and the upper end of the folded portion (320) of the yoke plate (310) (e.g., see FIG. 8). In this case, the first end (e.g., 400a of FIG. 8) of the mesh cover (400) may be stably fixed by being positioned between the conductor (221) and the upper end of the folded portion (320). The first end (e.g., 400a of FIG. 8) of the mesh cover (400) may be attached to the conductor (221) and the upper end of the folded portion (320) by an adhesive. The central portion (e.g., see 400b of FIG. 8) of the mesh cover (400) may be attached to the inner surface (e.g., 330 of FIG. 8) of the third support portion (323) of the folded portion (320) by an adhesive. Additionally, the central portion of the mesh cover (400) (e.g., 400c in FIG. 8) may be attached to a portion of the inner surface of the first support portion (321) and a portion of the inner surface of the second support portion (322) by an adhesive. Along the X-axis direction, the mesh cover (400) may overlap both the first support portion (321) and the second support portion (322), and may extend across all gaps defined along the side walls (e.g., the bent portion 320) of the third support portion (323) and the yoke plate (310).

[0082] The mesh cover (400) may include a flexible, air-permeable material. For example, the mesh cover (400) may be a fibrous material such as a non-woven fabric or cloth. The mesh cover (400) may include a plurality of ventilation holes through which the rear sound output from the lower side of the diaphragm (211) may pass from the inside to the outside of the speaker module (181). The size of the plurality of ventilation holes may vary depending on the density of the fibers when weaving the fibers. In this way, the mesh cover (400) as a breathable and / or sound-permeable material can adjust the damping of the rear sound by adjusting the size of the plurality of ventilation holes.

[0083] Fig. 8 is an enlarged view showing a portion of a cross-section of a speaker module (181) taken along line A-A' shown in Fig. 3 according to one embodiment. Fig. 9 is an enlarged view showing a portion of a cross-section of a speaker module (181) according to one embodiment.

[0084] Referring to FIGS. 8 and 9, the yoke plate (310) (particularly, the base plate) may cover the entire lower portion of the speaker module (181). In order to install the mesh cover (400) inside the speaker module (181), the bent portion (320) of the yoke plate (310) may be arranged to extend to a point a certain distance from the lower portion of the frame (220). Due to this arrangement, the bent portion (320) of the yoke plate (310) may engage with the bent portion of the yoke plate (310) where the yoke plate (310) is coupled to the frame (220). The side walls and the base plate of the yoke plate (310) may be each part of a single body (e.g., integral), or may be separate bodies that are assembled together to form the yoke plate (310).

[0085] The inner magnet (510) and the outer magnet (520) may be arranged on the upper side of the yoke plate (310). That is, the inner magnet (510) and the outer magnet (520) may be arranged on the upper side of the yoke plate (310), that is, between the facing bends along the Y-axis direction. The inner magnet (510) and the outer magnet (520) may be arranged at a certain distance from each other. Due to this arrangement, the inner magnet (510) and the outer magnet (520) may form a magnetic field for moving the voice coil (240) up and down. (For example, the direction along the thickness direction of the speaker module (181), the Z-axis direction)

[0086] The voice coil (240) may be placed on the lower side of the diaphragm (211). In addition, the voice coil (240) may be placed between the inner magnet (510) and the outer magnet (520). The voice coil (240) may receive an electric signal through the conductor (221). When current flows through the voice coil (240), the voice coil (240) may move up and down within the magnetic field formed by the inner magnet (510) and the outer magnet (520). This movement of the voice coil (240) may be directly transmitted to the diaphragm (211). The diaphragm (211) may generate sound waves by compressing and expanding air while moving up and down.

[0087] In one embodiment, the conductor (221) may be (e.g., electrically) connected to the voice coil (240) to apply current to the voice coil (240). An example of such a connection is shown by the dotted line between the conductor (221) and the voice coil (240), but is not limited thereto.

[0088] The thickness of the base plate of the yoke plate (310) can be defined along the thickness direction of the speaker module (181), i.e., the Z-axis direction. The yoke plate (310) can be thinner in the space between the inner magnet (510) and the outer magnet (520) along the Y-axis direction than in other locations. Accordingly, the speaker module (181) can have a reduced magnetic resistance within the magnetic circuit, and since more space is provided in the portion where the thickness of the yoke plate (310) is reduced, the density of the magnetic field can be increased.

[0089] The inner magnet (510) and the outer magnet (520) may each include an additional yoke plate (511, 521) on the upper surface. The inner magnet (510) and the outer magnet (510) may increase the density of the magnetic field by arranging the yoke plate (310) on the lower surface and the additional yoke plate (511, 521) on the upper surface.

[0090] Referring to Fig. 8, the speaker module (181) may have a conductor (221) disposed on the lower side of the frame (220). The first end (400a) of the mesh cover (400) may be disposed between the conductor (221) and the folded portion (320). The upper side of the first end (400a) of the mesh cover (400) may be attached to the lower side of the conductor (221) by an adhesive, and the lower side of the first end (400a) of the mesh cover (400) may be attached to the upper side of the folded portion (320) by an adhesive. The conductor (221) may not be positioned at the lower end of the frame (220), but may be disposed on the housing (101). If the conductor (221) is composed of a flexible printed circuit board (FPCB), it may be attached to the outer side of the housing (101) or the frame (220). In this case, the voice coil (240) can receive current from the outside of the speaker module (181). In this case, as shown in FIG. 9, the first end (400a) of the mesh cover (400) can be placed between the frame (220) and the folded portion (320). The upper surface of the first end (400a) of the mesh cover (400) can be attached to the lower surface of the frame (220) by an adhesive, and the lower surface of the first end (400a) of the mesh cover (400) can be attached to the upper surface of the folded portion (320) by an adhesive.

[0091] Although the mesh cover (400) is described in various ways as being attached to the upper surface of the conductor (221), frame (220), and bending portion (320) using adhesive, the present invention is not limited thereto. In an embodiment, the mesh cover (400) may be attached by a method such as directly attaching it to these various elements to form an interface therebetween.

[0092] The second end (400b) of the mesh cover (400) can be attached to the upper surface of the yoke plate (310), i.e., the upper side surface of the base plate. The central portion (400c) of the mesh cover (400) can be attached to the inner surface of the folded portion (320). At various positions between the first end and the second end of the mesh cover (400) along the Y-axis direction, the mesh cover (400) can have a thickness of 40 μm to 300 μm. For example, when the outer cover of the speaker module (181) is sturdy and the risk of damage to the speaker module (181) is low, the thickness of the mesh cover (400) can be set to approximately 40 micrometers. Accordingly, the sound quality of the speaker module (181) can be further improved.

[0093] In cases where there is no outer cover of the speaker module (181) and thus there is a possibility that fine particles or foreign substances of sound-absorbing material may enter the interior of the speaker module (181), the mesh cover (400) may have a thickness of up to 300 μm to increase the overall strength of the speaker module (181).

[0094] If the thickness of the mesh cover (400) is less than 40 μm, the mesh cover (400) can be easily torn by small sound-absorbing material particles or foreign substances that impact the mesh cover (400). Accordingly, the small sound-absorbing material particles or foreign substances can enter the speaker module (181).

[0095] If the thickness of the mesh cover (400) exceeds 300 μm, the first end (400a) of the mesh cover (400) may not be easily inserted between the lower end of the frame (220) and the upper end of the folded portion (320). In addition, if the thickness of the mesh cover (400) exceeds 300 μm, the breathability decreases, reducing the amount of rear sound emission, making it difficult to provide rich sound from the speaker module (181).

[0096] Fig. 10 is a perspective view showing a frame (220) of a speaker module (181) according to one embodiment.

[0097] Referring to Fig. 10, the frame (220) may be configured in a closed loop shape of approximately a square. A conductor (221) may be coupled to the lower end of the frame (220). The conductor (221) may include a first conductor (221a) disposed at a left edge of the frame (220), a second conductor (221b) disposed at a right edge of the frame (220), and a third conductor (221c) disposed at a central portion of the frame (220). The first conductor (221a), the second conductor (221b), and the third conductor (221c) may be physically and / or electrically connected to each other. For example, the conductor (221) may be connected to an FPCB while being disposed at the lower end of the frame (220), thereby providing resistance to vibration and shock.

[0098] As a first insulator, a first conductor (221a) and as a second insulator, a second conductor (221b) may be arranged at the side surface from the bottom of the frame (220), i.e., along the periphery of the frame (220). As a third insulator, a third conductor (221c) may be arranged in the interior of the frame (220) at the center of the frame (220) (e.g., an open area of ​​a closed loop shape). Each of the various sub-conductors may overlap with a solid portion of the frame (220) along the thickness direction and may extend laterally further than the solid portion in a direction toward the outside and / or inside of the closed loop shape. The first conductor (221a), the second conductor (221b), and the third conductor (221c) may be made of an electrically and / or thermally conductive material, and may be composed of one of metal, copper, and aluminum. The sub-conductors (221) are not limited thereto and may be formed integrally with the conductor (221).

[0099] Fig. 10 illustrates conductors (221a, 221b, and 221c) coupled to one side of a frame (220) along the Y-axis. Another conductor configured symmetrically to the conductors (221a, 221b, and 221c) may also be coupled to the opposite side of the frame (220). Fig. 11 is a side view of a speaker module (181) according to one embodiment. The side view extends in the XZ plane.

[0100] Referring to FIG. 11, the speaker module (181) may include a frame (220) on the upper side and a conductor (221) on the lower side of the frame (220). The lower side of the conductor (221) may include a base plate of a yoke plate (310), a bent portion (320) of the yoke plate (310), and a mesh cover (400).

[0101] The upper outer side of the first end (400a) of the mesh cover (400) can be attached to the lower surface of the conductor (221) on the outer surface of the speaker module (181). The upper central part of the first end (400a) of the mesh cover (400) can be directly attached to the lower surface of the frame (220). According to another embodiment, although not shown in FIG. 11, when the conductor (221) is not present, the upper side of the first end (400a) of the mesh cover (400) can be attached entirely to the lower surface of the frame (220).

[0102] The first width (W1) from the left side of the first opening (320a) to the right side of the second opening (320b) may be the sum of the second width (W2) of the third support member (323), the third width (W3) of the first opening (320a), and the fourth width (W4) of the second opening (320b).

[0103] The third width (W3) of the first opening (320a) and the fourth width (W4) of the second opening (320b) may be the same. The second width (W2) of the third support portion (323) may be narrower than the third width (W3) of the first opening (320a). Similarly, the second width (W2) of the third support portion (323) may be narrower than the fourth width (W4) of the second opening (320b).

[0104] The first opening (320a) and the second opening (320b) may be symmetrical left and right with respect to the third support member (323). Accordingly, the third width (W3) of the first opening (320a) and the fourth width (W4) of the second opening (320b) may also be symmetrical left and right with respect to the third support member (323).

[0105] The second width (W2) of the third support member (323) may be 0.2 to 0.5 times the third width (W3) of the first opening (320a). Similarly, the second width (W2) of the third support member (323) may be about 0.2 to 0.5 times the fourth width (W4) of the second opening (320b). For example, if the central portion (400c) of the mesh cover (400) can be stably attached to the inner side of the side of the first support portion (321) and the second support portion (322), there is no problem even if the width (W2) of the third support portion (323) is narrow, so the second width (W2) of the third support portion (323) can be 0.2 times the width (W3) of the first opening (320a) or the fourth width (W4) of the second opening (320b). Conversely, if the central portion (400c) of the mesh cover (400) cannot be stably attached to the inner side of the first support portion (321) and the second support portion (322), the second width (W2) of the third support portion (323) may be about 0.5 times the third width (W3) of the first opening (320a) or the fourth width (W4) of the second opening (320b).

[0106] If the width (W2) of the third support (323) is less than about 0.2 times the third width (W3) of the first opening (320a) or the second width (W4) of the second opening (320b), the mesh cover (400) cannot be stably attached to the third support (323). If the second width (W2) of the third support (323) is more than about 0.5 times the third width (W3) of the first opening (320a) or the fourth width (W4) of the second opening (320b), the rear sound of the speaker module (181) may not be properly emitted, resulting in poor sound quality.

[0107] FIG. 12 is a side view of the outer surface of a speaker module (181) according to an embodiment further including a hole (324) capable of additionally emitting overtones in the central portion of the third support member (323) illustrated in FIG. 11.

[0108] Referring to Fig. 12, the hole (324) positioned in the center of the third support member (323) may be a circular plane. However, it is not limited thereto, and may have various plane shapes such as a square or polygon.

[0109] Additionally, the hole (324) positioned in the center of the third support member (323) may have a flat slot shape. Through the slot shape, the directionality of the rear sound emitted from the speaker module (181) to the outside can be more delicately adjusted.

[0110] The hole (324) may be a closed opening defined by a solid portion of a side wall of the yoke plate in the third support portion (323) of the yoke plate (310). The hole (324) may completely penetrate the solid portion along the Y-axis direction and may be open on both the outer surface and the inner surface of the solid portion in the third support portion (323). The mesh cover (400) may extend across the hole (324) as if similarly arranged in various openings of the side wall of the yoke plate (310).

[0111] Fig. 13 is a side view of the outer surface of the speaker module (181) with the third support member (323) of Fig. 11 removed. (See, for example, Fig. 6)

[0112] Referring to Fig. 13, the distance between the right side of the first support member (321) and the left side of the second support member (322) facing the right side can be the fifth width (W11) of the continuous opening (320c).

[0113] The central portion (400c) of the mesh cover (400) can be attached only to a portion of the inner side of the first support portion (321) and the second support portion (322), and can be fully extended across the continuous opening (320c).

[0114] The mesh cover (400) may be made of a fiber material or a sponge material. The fiber material applied to the mesh cover (400) can adjust the size of the air holes when weaving the fiber. Accordingly, the speaker module (181) can adjust the damping of the rear sound.

[0115] In addition, the mesh cover (400) may have a flexible material. When an external impact is applied to the speaker module (181), the mesh cover (400) can not only be an air (or sound) permeable member, but also act as a shock absorbing member to absorb the external impact. Accordingly, the mesh cover (400) can be less likely to be detached from the support member (321, 322).

[0116] Fig. 14 is a perspective view of the lower portion of a speaker module (181) according to one embodiment. Fig. 15 is a drawing showing a part of a cross-sectional view of the combined form of Fig. 14 according to one embodiment.

[0117] The driver (210) of the speaker module (181) includes components necessary to actually drive the speaker module (181). For example, the driver (210) may include a vibration plate (1211), a frame (1220), a suspension (1230), and a voice coil (1240).

[0118] Referring to FIG. 14, the speaker module (181) may include a yoke plate (1310), a bent portion (1320), and a mesh cover (1400). The bent portion (1320) may include a first region (1321) representing a side portion and a second region (1322) representing a bottom portion. The first region (1321) may form a side wall of the entire yoke plate (310) extending from a sub-plate of the bent portion (1320). The base plate of the yoke plate (310) may be a separate plate from the bent portion (1320), as illustrated in FIGS. 14 and 15. Here, the entire yoke plate (310) is not a single piece.

[0119] The first region (1321) may include two openings (1320a, 1320b) as closed openings. Unlike the bending portion (320) illustrated in FIG. 4, the first region (1321) may further include an additional member (1321a) at the upper end of the first region (1321). The additional member (1321a) may be positioned at the upper end of the bending portion (1320). Accordingly, when the first end (400a) of the mesh cover (400) is coupled between the lower end of the frame (220) and the upper end of the bending portion (1320), the additional member (1321a) may more stably support the lower end of the first end (400a) of the mesh cover (400). However, although FIG. 12 shows two openings (1320a, 1320b), it is not necessarily limited to this and may be composed of a single opening or at least three or more openings.

[0120] By further including an additional member (1321a) on the upper part of the first region (1321), the upper part of the mesh cover (1400) can be more firmly attached when compressed between the folded part (1320) and the frame (1220).

[0121] The lower surface of the second region (1322) of the bend portion (1320) can be attached to the upper surface of the yoke plate (1310). For example, the second region (1322) of the bend portion (1320) can be bonded to the yoke plate (1310) by an adhesive. The second region (1322) of the bend portion (1320) can be joined to the yoke plate (1310) by ultrasonic welding. This provides a direct connection in which the sub plate and the base plate contact each other. The contacting elements are not limited to direct connection, but can form an interface therebetween. Accordingly, the yoke plate (1310) and the bend portion (1320) can have increased durability, and can more effectively protect the mesh cover (1400) disposed therein.

[0122] Referring to Fig. 15, the length of the second region (1322) in the X-axis direction may be longer than the length of the second end (1400b) of the mesh cover. Accordingly, the entire lower surface of the second end (1400b) may be attached to the upper surface of the second region (1322), thereby reducing the possibility of detachment of the mesh cover (1400).

[0123] The bending portion (1320) is separable from the yoke plate (1310). Accordingly, even if the bending portion (1320) is damaged by external impact, it can be easily replaced. The base plate of the yoke plate (1310) may include the parts (1310 and 1311) shown in FIGS. 14 and 15, but is not limited thereto, and the base plate may be formed integrally.

[0124] The bending portion (1320) may be composed of metal or an elastic material. If the bending portion (1320) is composed of metal, the thickness of the bending portion (1320) may be adjusted within an appropriate range, taking into account the specifications of the speaker module (181). If the bending portion (1320) is composed of an elastic material, the bending portion (1320) may absorb external impacts to prevent or minimize damage.

[0125] The lower end of the second region (1322) of the bending portion (1320) can be attached to the upper end of the side portion (1311) of the yoke plate (1310). The lower end and the upper end can be defined by the sub plate and the base plate, respectively. Referring to FIG. 15, the side portion (1311) of the yoke plate (1310) can be formed to be longer in the X-axis direction than the lower end of the second region (1322) of the bending portion (1320) so as to sufficiently secure a surface to be joined to the lower end of the second region (1322) of the bending portion (1320).

[0126] The inner magnet (1510) and the outer magnet (1520) may be arranged between the upper side of the yoke plate (1310), i.e., the side walls facing each other along the Y-axis direction. The inner magnet (1510) and the outer magnet (1520) may be arranged to be spaced apart from each other by a specific distance. Due to this arrangement, the inner magnet (1510) and the outer magnet (1520) may form a magnetic field therebetween for moving the voice coil (1240) in an up-and-down direction (e.g., in the thickness direction of the speaker module (181), along the Z-axis direction).

[0127] The voice coil (1240) may be placed on the lower side of the diaphragm (1211). Additionally, the voice coil (1240) may be placed between the inner magnet (1510) and the outer magnet (1520). The voice coil (1240) may receive an electric signal through the conductor (1221).
