Description

Speaker device including a slot-type speaker unit

[0001] The present disclosure relates to a speaker device including a slot-type speaker unit.

[0002] A speaker device is a device that converts an electrical signal into an acoustic signal and radiates it.

[0003] Typically, a speaker device comprises a box-shaped enclosure with an internal space and a speaker unit in which a diaphragm vibrates to generate an acoustic signal. The speaker unit can generate acoustic signals across a wide range of frequencies, covering from low to high frequencies.

[0004] As electronic devices became slimmer, the size of the associated speakers also had to be reduced, so slot-loading loudspeakers (SLLs) were developed, in which the sound signal radiating holes were designed in the shape of slots.

[0005] Recently, electronic devices that incorporate a decorative panel in front of a slot-type loudspeaker have been developed and distributed to enhance aesthetic appeal.

[0006] In these electronic devices, some of the audio signals output through the slot may be reflected from the back or inside of the panel, interfering with the audio signals output directly through the slot. This can distort the amplitude spectrum of the audio signal, resulting in degraded sound quality.

[0007] Aspects of embodiments of the present disclosure will be set forth in part in the following description, and in part will be obvious from the description or may be learned by the examples presented.

[0008] According to at least one embodiment of the present disclosure, a speaker device may include a housing; a slot-radiating speaker disposed inside the housing; and a panel member disposed in front of the slot-radiating speaker. The slot-radiating speaker may include a speaker unit; and a cover covering an opening for outputting an acoustic signal generated by the speaker unit. The panel member may form a gap between the cover and the speaker unit, and an exposed area is formed between an edge of the housing and an edge of the panel member for transmitting the acoustic signal output through the opening to the outside, and at least one of the cover and the panel member may include at least one blocking member for blocking at least a portion of the acoustic signal output through the opening from entering the gap.

The first blocking member may be present integrally with the cover or may be present made of a different material, and the second blocking member may be present integrally with the panel member or may be present made of a different material.

[0016] According to at least one embodiment of the present disclosure, the at least one blocking member may include a first blocking member protruding from a front surface of the cover; and a second blocking member protruding from a rear surface of the panel member. The first blocking member may be of a form that does not contact the second blocking member.

[0017] According to at least one embodiment of the present disclosure, an auxiliary member may further be included between the first blocking member and the second blocking member.

[0018] According to at least one embodiment of the present disclosure, the auxiliary member may be an Acoustic Meta Material (AMM).

[0019] According to at least one embodiment of the present disclosure, the at least one blocking member may be arranged in multiple numbers on at least one of the front surface of the housing and the rear surface of the panel member.

[0020] According to at least one embodiment of the present disclosure, the blocking member may further include an auxiliary member disposed on the front surface of the cover and the rear surface of the panel member.

[0032] The embodiments described below are provided as examples to aid in understanding the present disclosure, and it should be understood that the present disclosure may be implemented in various ways other than the embodiments described herein. However, in the following description of the present disclosure, if it is determined that a specific description of a related known function or component may unnecessarily obscure the gist of the present disclosure, a detailed description and specific illustration thereof will be omitted. In addition, the attached drawings are not drawn to scale to aid in understanding the disclosure, and the dimensions of some components may be exaggerated.

[0033] The terms used in this specification and claims are general terms selected in consideration of the functions of the present disclosure. However, these terms may vary depending on the intentions of those skilled in the art, legal or technical interpretations, and the emergence of new technologies. Furthermore, some terms may have been arbitrarily selected by the applicant. These terms may be interpreted according to the meanings defined in this specification. In the absence of a specific definition, they may be interpreted based on the overall content of this specification and common technical knowledge in the relevant technical field.

[0034] In the description of this disclosure, the order of each step should be understood as non-limiting, unless a preceding step logically and temporally must be performed before a succeeding step. In other words, except in exceptional cases such as the above, even if a process described as a succeeding step is performed before a process described as a preceding step, the essence of the disclosure is not affected, and the scope of the rights should be defined regardless of the order of the steps.

[0035] In this specification, expressions such as “has,” “can have,” “includes,” or “may include” indicate the presence of a feature (e.g., a number, function, operation, or component such as a part), and do not exclude the presence of additional features.

[0036] While terms like "first" and "second" may be used to describe various components, these components should not be limited by these terms. These terms may only be used to distinguish one component from another. For example, without departing from the scope of the present disclosure, a first component could be referred to as a "second component," and similarly, a second component could also be referred to as a "first component."

[0037] In addition, terms such as 'front', 'rear', 'top', 'bottom', 'side', 'left', 'right', 'upper', and 'lower' used in the present disclosure are defined based on the drawings, and the shape and position of each component are not limited by these terms.

[0038] Furthermore, while this specification describes the components necessary for explaining each embodiment of the present disclosure, it is not necessarily limited to these components. Accordingly, some components may be changed or omitted, and other components may be added. Furthermore, the components may be distributed and deployed across different, independent devices.

[0039] Furthermore, in connection with the description of the drawings, similar reference numerals may be used for similar or related components.

[0040] The singular form of a noun corresponding to an item may include one or more of said items, unless the relevant context clearly indicates otherwise.

[0041] 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.

[0042] The term "and / or" includes any combination of a plurality of related described elements or any one of a plurality of related described elements.

[0043] 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).

[0044] 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.

[0045] The terms "include" or "have" 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.

[0046] 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.

[0047] When we say that a component is "on" another component, this includes not only cases where the component is in contact with the other component, but also cases where there is another component between the two components.

[0048] Below, speaker devices according to various embodiments are specifically described with reference to the attached drawings.

[0049] FIG. 1 is a perspective view of a speaker device according to one embodiment of the present disclosure. Referring to FIG. 1, the speaker device (1) may include a housing (10), a panel member (20), etc.

[0050] The housing (10) represents the main body of the speaker device (1). The housing (10) may be described by various terms such as packaging, box, body, etc.

[0051] The housing (10) houses a number of electronic devices, batteries, etc. inside, and can serve to protect these devices. The housing (10) can be implemented in various forms, such as a stand-type form that can be erected on the floor, a wall-mounted form that can be hung on a wall, or a form that is hung by a wire from the ceiling.

[0052] In Fig. 1, a housing (10) implemented in a square shape is illustrated, but it is not limited thereto and may have various shapes such as a circle or polygon.

[0053] A panel member (20) can be formed on the front side of the housing (10).

[0054] The panel member (20) can be composed of various materials such as plastic materials such as PVC, acrylic, polycarbonate, glass materials, rubber materials, wood materials, and metal materials.

[0055] The panel member (20) may be implemented in a form that is detachable from the housing (10). A picture may be drawn on the front of the panel member (20), or a display may be provided to display an image. Accordingly, the user may use the speaker device (1) to which the panel member (20) is attached as if it were a picture frame. If the panel member (20) is designed like a picture frame, the user may replace it at any time according to his / her taste. If the panel member (20) is provided with a display, the user may change the image to be displayed at any time according to his / her taste. The image change may be transmitted to the panel member (20) or the speaker unit using a portable memory such as a USB stick memory, or may be transmitted through a mobile phone, tablet, PC, laptop PC, etc. that is wirelessly or wiredly connected to the panel member (20) or the speaker unit. Alternatively, the image may be downloaded through a server device.

[0056] When the panel member (20) is attached to the front, it may be difficult to output an acoustic signal toward the front of the speaker device (1). When the speaker unit is formed toward the front of the speaker device (1), the panel member (20) covers the front surface thereof, so that a portion of the speaker unit is obscured. Accordingly, the thickness of the panel member (20) can be made thin so that the acoustic signal radiated from the speaker unit can be well transmitted to the outside.

[0057] According to at least one embodiment of the present disclosure, the panel member (20) may be spaced apart from the front surface of the slot radiating speaker at a position that does not obscure the opening. In addition, an exposed area (100) may be formed between the edge of the housing (10) and the edge of the panel member for transmitting an acoustic signal output through the opening to the outside.

[0058] The exposure area (100) can be replaced with various expressions such as boundary area, public area, transparent area, gap area, etc.

[0059] Meanwhile, according to at least one embodiment of the present disclosure, the panel member (20) is connected based on the center of the speaker device (1), i.e., the center of the housing (10). When the area of ​​the panel member (20) is smaller than the area of ​​the housing (10), at least one edge of the upper, lower, left, and right edges of the housing (10) may be exposed. FIG. 1 illustrates a case where all of the upper, lower, left, and right edges are exposed areas (100). The slot-radiating speaker may be disposed on the rear surface of the exposed area (100). Specifically, an opening for transmitting an acoustic signal radiated from the slot-radiating speaker to the outside is disposed on the rear surface of the exposed area (100). Accordingly, even if a part of the speaker unit is covered by the panel member (20), the acoustic signal can be well transmitted to the user through the opening formed in the exposed area (100) that is not covered by the panel member (20).

[0060] In Fig. 1, a gap may be formed between the housing (10) and the panel member (20).

[0061] In the case of a conventional speaker device, even if the opening is positioned in the exposed area (100), some of the sound signals output through the opening may flow into the gap. The sound signals that flow in are transmitted to the gap and then reflected, and the sound signals directly radiated from the speaker unit and the indirectly reflected sound signals may mutually reinforce and / or cancel each other, which may cause the amplitude spectrum of the sound signal to be distorted and the sound quality to deteriorate.

[0062] Specifically, when the sound signal output directly and the sound signal reflected inside the gap meet with the same phase or aligned phase, constructive interference occurs, and when they meet with opposite phases, destructive interference occurs.

[0063] When constructive interference occurs, the amplitudes of individual sound signals are added together to transmit a sound signal with an amplitude greater than the volume set by the user, and when destructive interference occurs, the volume of the sound signal may be reduced or almost disappear.

[0064] FIG. 2 is a schematic diagram of a cross-sectional configuration of a speaker device (1) according to various embodiments of the present disclosure.

[0065] According to FIG. 2, the speaker device (1) includes a housing (10), a slot radiating speaker arranged inside the housing, and a panel member (20).

[0066] Slot-radiating speakers are specially designed audio equipment that emit sound through a narrow slot, or opening (41). This allows for fine adjustment of sound directionality and improved sound quality in specific frequency bands. Furthermore, they can optimize acoustic design and, by using a narrow slot, reduce the size of the speaker itself, maximizing space utilization.

[0067] According to Fig. 2, two slot-radiating speakers are arranged symmetrically on both side edges of the housing (10). However, this is not limited to this, and only one slot-radiating speaker may be arranged on one side, or multiple slot-radiating speakers may be arranged on both sides instead of just one.

[0068] A slot-radiating speaker can be composed of a speaker unit (31), an opening (41), a cover (51), etc. The opening (41) is formed to penetrate the cover (51) so as to output an acoustic signal generated from the speaker unit (31). When a slot-radiating speaker is used, even if the panel member (20) is coupled to the front of the housing (10), an acoustic signal can be output to the outside through the exposed area between the panel member (20) and the housing (10).

[0069] Referring to FIGS. 1 and 2, it is shown that an exposed area (100) is formed between the edge of the panel member (20) and the edge of the housing (10), but this may vary depending on the connection position or shape of the panel member (20). For example, the exposed area may be formed in the center or other inner area rather than near the edge of the housing (10). The panel member (20) may be positioned at an appropriate position so that the exposed area does not block the sound signal output through the opening (41). FIGS. 1 and 2 illustrate a case where the opening (41) is positioned near the edge of the housing (10) and the exposed area (100) is formed on the front surface of the opening (41).

[0070] A gap is formed between the cover (51) and the panel member (20) by the panel member (20) being spaced apart from the opening (41) at the front surface of the slot radiating speaker. At least a portion of the sound signal output through the opening (41) may be introduced into the gap. Accordingly, according to at least one embodiment of the present disclosure, the speaker device (1) includes at least one blocking member (90) for blocking the introduction of sound signals into the gap. In the present disclosure, blocking should be interpreted to mean not only preventing the introduction from occurring at all, but also minimizing the inflow rate. The blocking member (90) may be manufactured in various forms according to various embodiments of the present disclosure. The blocking member (90) may be formed in at least one of the cover (51) and the panel member (20), but may also be formed in various other configurations.

[0071] In Fig. 2, a case is shown where a blocking member (90) is formed on the surface of a cover (51). The blocking member (90) may be an integrated structure made of the same material as the cover (51), or may be a structure manufactured separately from a material different from the cover (51) and then attached or combined.

[0072] The blocking member (90) may be manufactured in a shape to reduce the size of the gap. According to one embodiment of the present disclosure, the blocking member (90) may be in a shape that protrudes toward the panel member (20). Here, the blocking member (90) may be in a shape that contacts the panel member or may not contact the panel member.

[0073] According to one embodiment of the present disclosure of FIG. 2, the width (d1) between the panel member (20) and the blocking member (90) may be narrower than the width (d2) between the panel member (20) and the cover (51). That is, 0≤d1≤d2 may be satisfied. As a result, indirect reflection sound that is generated when sound emitted from the opening (41) enters the gap and is then reflected can be minimized or eliminated, thereby improving sound quality.

[0074] According to one embodiment of the present disclosure of FIG. 2, the blocking member (90) may have a rectangular parallelepiped shape.

[0075] According to one embodiment of the present disclosure of FIG. 2, the blocking member (90) may have a convex dome shape. However, the present invention is not limited thereto, and may have various shapes such as a pyramid shape.

[0076] According to one embodiment of the present disclosure of FIG. 2, an exposed area (100) may be formed between an edge of the housing (10) and an edge of the panel member for transmitting an acoustic signal output through an opening (41) to the outside. In addition, at least one of the cover (51) and the panel member (20) may include at least one blocking member (90) for blocking an acoustic signal output through the opening (31) from flowing into the gap (2).

[0077] According to one embodiment of the present disclosure of FIG. 2, an opening (41) is formed to penetrate the cover (51) so as to output an acoustic signal generated from the speaker unit (31).

[0078] According to one embodiment of the present disclosure of FIG. 2, an auxiliary member (not shown) may be further included on the surface of at least one of the panel member (20), the cover (51), and the blocking member (90). Here, the auxiliary member (not shown) may be an Acoustic Meta Material (AMM). However, the present invention is not limited thereto, and the auxiliary member (not shown) may use various other materials.

[0079] Figure 3 is an enlarged view of part 'B' of Figure 1.

[0080] Fig. 3 shows an enlarged view of a panel member (20) coupled to a housing (10). Fig. 3 shows a case where two slot-radiating speakers are arranged in the left edge area and two speaker units (31, 32) are arranged inside the two slot-radiating speakers. For convenience of explanation, one of them is hereinafter referred to as a first speaker unit (31) and the other as a second speaker unit (32). However, the present invention is not limited thereto, and the first speaker unit (31) may be referred to as a speaker unit or a main speaker unit, and the second speaker unit (32) may be referred to as an additional speaker unit or an auxiliary speaker unit. Both speaker units (31, 32) may be implemented as slot-type speaker units that output sound signals through openings. For convenience of explanation, the opening of the first speaker unit (31) is referred to as a first opening (41), and the opening of the second speaker unit (32) is referred to as a second opening (42).

[0081] However, the openings (41, 42) are not limited to this expression and may be replaced with various expressions such as slots, holes, gaps, radiation areas, and sound emission parts.

[0082] In Fig. 3, the first opening (41) is formed on the front surface of the first speaker unit (31).

[0083] In FIG. 3, the size of the panel member (20) can be configured to be smaller than the front size of the housing (10). Accordingly, when the panel member (20) is coupled based on the center of the housing (10), an exposed area (100) can be configured between the housing (10) and the panel member (20).

[0084] In FIG. 3, according to one embodiment of the present disclosure, the shape of the panel member (20) can be implemented in a square shape identical to the shape of the housing (10).

[0085] However, it is not necessarily limited thereto, and according to another embodiment, the length and width of the panel member (20) may be formed to be the same as the length and width of the housing (10), and may be implemented so that a part of the housing (10) is exposed when combined while being rotated at a predetermined angle. Alternatively, the panel member (20) may be combined in the same alignment, but a part (e.g., a corner) of the panel member (20) may be implemented in a cut-off form so that a part (e.g., a corner) of the housing (10) is exposed.

[0086] In FIG. 3, some of the acoustic signals emitted from the first speaker unit (31) can be directly emitted through the first opening (41) and the exposure area (100).

[0087] Another portion of the acoustic signal emitted through the first opening (41) may be emitted into the gap between the panel member (20) and the housing (10) rather than the exposed area (100).

[0088] Here, the acoustic signal emitted into the gap may be reflected and returned from the rear surface of the panel member (20) and / or the inner side of the housing (10) within the gap.

[0089] The reflected and returned acoustic signal may interfere with the acoustic signal directly emitted through the first opening (41) and the exposure area (100).

[0090] Through this, the sound signals may mutually reinforce and / or cancel each other out, which may result in a deterioration in sound quality.

[0091] According to various embodiments of the present disclosure, the gap between the speaker unit and the panel member is modified in various ways so that the gap varies depending on the distance between the cover and the panel member (20). Accordingly, by preventing the acoustic signal emitted from the speaker unit from being transmitted deep within the gap, the proportion of reinforcement / offset with the acoustic signal directly emitted through the opening can be significantly reduced.

[0092] Fig. 4 is an exploded perspective view showing the housing (10) and panel member (20) removed from the perspective view of Fig. 1.

[0093] The configuration of the housing (10) can be seen in more detail through Fig. 4.

[0094] The first cover (51) is a covering configuration of the first speaker unit (31). The first cover (51) forms the front surface of the first speaker unit (31). A first opening (41) is formed in the first cover (51).

[0095] In addition, the second cover (52) is configured to cover the first speaker unit (32). The second opening (42) may be formed in the second cover (52). Unlike the first opening (41), the second opening (42) may be implemented in the form of multiple slots in which each opening is divided by at least one partition wall. FIG. 3 illustrates a state in which the second opening (42) is divided into three openings.

[0096] In Fig. 4, the case in which the size of the second speaker unit (32) is larger than the size of the first speaker unit (31) and the size of the second cover (52) is also larger than the size of the first cover (51) is illustrated, but it is not necessarily limited to this, and the first and second speaker units (31, 32) may be implemented with the same size.

[0097] In addition, in FIG. 4, a plurality of first speaker units (31) are provided at the center of the left edge and the center of the right edge among the upper, lower, left, and right edges of the housing (10), and a plurality of second speaker units (32) are arranged at positions (front side in the case of FIG. 3) spaced apart from the first speaker unit (31) along the left edge and the right edge. However, the number, arrangement positions, sizes, shapes, etc. of the first and second speaker units (31, 32) can be varied.

[0098] The first speaker unit (31) and the second speaker unit (32) can each be implemented in different speaker shapes.

[0099] For example, the first speaker unit (31) may be a mid-range speaker responsible for the middle sound range, and the second speaker unit (32) may be a tweeter speaker responsible for the high-frequency sound range.

[0100] According to another embodiment, the first speaker unit (31) may be a tweeter responsible for a high-frequency sound range, and the second speaker unit (32) may be a mid-range speaker responsible for a middle sound range.

[0101] According to another embodiment, the first speaker unit (31) and the second speaker unit (32) may be configured with at least one of a tweeter, a mid-range, and a woofer.

[0102] Since the first and second speaker units (31, 32) are positioned on the rear side of the panel member (20), if they output sound signals as they are, the sound signals may not be properly transmitted to the outside by the panel member (20). To prevent this, covers (51, 52) including openings (41, 42) that output sound signals radiated from the first and second speaker units (31, 32) to the outside through the exposure area (100) are used. Through the first cover (51) and / or the second cover (52), the sound quality of the low-pitched sound signal output from the speaker device (1) is improved, and unwanted noise or distortion can be reduced.

[0103] Additionally, through the first cover (51) and / or the second cover (52), the speaker device (1) has the effect of being able to accurately reproduce sound even at lower frequencies.

[0104] Additionally, through the first cover (51) and / or the second cover (52), the speaker device (1) can expand the frequency range and transmit sound effectively.

[0105] In addition, the speaker unit (31, 32) can be placed inside the electronic product (e.g. housing (10)) through the first cover (51) and / or the second cover (52), thereby enabling efficient use of space.

[0106] The material of the first cover (51) and / or the second cover (52) may vary depending on the purpose. Specifically, it may be composed of various materials such as plastic, metal, wood, and fabric.

[0107] Here, plastic materials are lightweight and easy to process. Metal offers superior durability and can have a less detrimental effect on sound quality. Wood can be used when design is a priority. Fabric offers excellent acoustic transparency and can protect the speaker unit without compromising sound quality.

[0108] A fastening portion (70) may be formed on the inside of each corner of the front surface of the housing (10), and a valve (60) may be formed in the center of the front surface of the housing (10).

[0109] The fastening member (70) is a configuration provided to attach and / or detach the panel member (20) from the housing (10). Through this, the panel member (20) can be coupled or detached.

[0110] According to one embodiment of the present disclosure, the fastening portion (70) may be configured as a circular groove or a protruding structure. However, the present invention is not limited thereto, and the fastening portion (70) may also be configured as a polygonal groove or may be configured in the form of a magnet or the like.

[0111] According to one embodiment of the present disclosure, one fastening member (70) may be placed at each corner of the front surface of the housing (10).

[0112] A fastening member (not shown) may be formed at each corner of the rear surface of the panel member (20). The fastening member may be provided with a protruding structure or a rough structure, etc. If the fastening member (not shown) is formed with a protruding structure and the fastening portion (70) is formed with a groove, the fastening member may be fastened in a form in which it is inserted into the fastening portion (70). Through the joining of the fastening member (not shown), the panel member (20) can be fixed to the housing (10).

[0113] Although not shown in the drawing, according to another embodiment, the fastening portion (70) may be formed as one in the center of the plate (60). For example, the fastening portion (70) may be formed as a circular groove in the center of the plate (60), and a fastening member (not shown) may be attached to the lower surface of the panel member (20). Through this, the panel member (20) may be fixed by coupling the fastening member (not shown) to the fastening portion (70).

[0114] The fastening member (not shown) and fastening portion (70) may be implemented in a form that includes a magnet or the like for magnetic coupling.

[0115] Figure 5 is an enlarged drawing of part 'C' of Figure 4, and Figure 6 is an enlarged drawing of part 'D' of Figure 5.

[0116] According to one embodiment of the present disclosure, the first speaker unit (31) may be circular and the second speaker unit (32) may be oval in which the height of the second speaker unit (32) is longer than the width of the second speaker unit (32).

[0117] However, it is not limited to this and can have various shapes such as squares and polygons.

[0118] Through the first and second speaker units (31, 32), an electrical signal can be converted into an acoustic signal to generate sound. The internal configuration of the first and second speaker units (31, 32) can be of various types, such as a tweeter, a woofer, a mid-range, and a full-range, depending on the frequency range of the acoustic signal.

[0119] Here, a woofer is specialized for low-frequency sounds such as bass, a mid-range speaker is specialized for the mid-frequency range, and a tweeter is specialized for high-frequency sounds. Furthermore, a full-range speaker is designed to cover the entire frequency range, from low to high.

[0120] In the inner central area of ​​the housing (10), other than the exposed area (100), a valve (60) may be provided to protect internal electronic components. The internal electronic components of the speaker may include a battery, a transducer, etc.

[0121] Referring to FIGS. 4 and 5, the valve (60) may have a square shape.

[0122] However, it is not limited to this and can have various shapes such as circles and polygons.

[0123] In Fig. 5, a fixing member (61) is placed between the housing (10) and the valve (60) to fix the valve (60) to the housing (10).

[0124] Although only a portion is shown in Fig. 5, the fixing member (61) can be placed at each corner of the front surface of the valve (60).

[0125] The fixed member (61) is in the form of a screw fastening and is composed of a screw bolt, screw, etc.

[0126] In Fig. 6, the slot radial loudspeaker features a structure in which the transducer is built into the enclosure.

[0127] A transducer (not shown) is placed inside the first speaker unit (31), and the enclosure may include a first opening (41), a first cover (51), etc.

[0128] A transducer (not shown) generates an acoustic signal by the vibration of a diaphragm. The transducer (not shown) converts an electrical signal into an acoustic signal and can generate acoustic signals in a wide range of frequencies, from low to high.

[0129] In Fig. 6, the shape of the first cover (51) is a mesh shape. The first cover (51) can be placed at a certain interval on the front of the first speaker unit (31). When viewed vertically from above, the center of the mesh of the first cover (51) can coincide with the center of the first speaker unit (31).

[0130] In Fig. 6, the first opening (41) can be placed next to the first cover (51).

[0131] In Fig. 6, the first opening (41) may have a shape that exposes a part of the first speaker unit (31). However, this is not limited to this, and the cross-section of the first opening (41) may have various shapes such as a rectangle, an oval, or a circle.

[0132] FIGS. 7 to 12 are drawings showing a portion of a cross-section cut along the AA' axis of FIG. 1. In FIGS. 7 to 12, the speaker device (1) may be composed of a panel member (20), a first speaker unit (31), a first opening (41), a first cover (51), a blocking member (90), a plate (60), a fastening member (70), and a support (not shown).

[0133] Specifically, in FIGS. 7 to 12, a first slot radiation cover (51) is arranged on the outer side of a plate (60), a first speaker unit (31) is arranged on the rear side of the first slot radiation cover (51), and a panel member (20) is arranged on the front side of the plate (60). As illustrated in FIGS. 7 to 12, a gap is formed between the first cover (51) and the panel member (20).

[0134] In FIGS. 7 to 12, the support (not shown) can serve to support the components of each electronic device so that they are arranged according to the standard and do not shake.

[0135] The material of the support (not shown) can be composed of various materials such as plastic, metal, ceramic, and composite materials.

[0136] The enclosure can be configured through a first cover (51) on the front side of the first speaker unit (31), a support (not shown) supporting the rear side of the first speaker unit (31), etc.

[0137] In FIGS. 7 to 12, the first cover (51) and the blocking member (90, 91, 92) are shown as having a convex cross-section, but are not limited thereto, and the cross-section may have an angular shape such as a rectangle, trapezoid, or the like, in addition to a semicircular shape.

[0138] In FIGS. 7 to 12, the first cover (51) and the blocking member (90, 91, 92) may further include an auxiliary member (not shown).

[0139] According to one embodiment of the present invention of FIGS. 7 to 12, the auxiliary member (not shown) may be an Acoustic Meta Material (AMM). According to one embodiment of the present invention of FIGS. 7 to 12, the auxiliary member (not shown) may completely cover the surface of the cover (51, 52) and the rear surface of the panel member (20), or may only partially cover the surface.

[0140] According to one embodiment of the present invention of FIG. 7, the blocking member may be present on the surface of the first cover (51).

[0141] Additionally, the blocking member may be integrated with the same material as the first cover (51).

[0142] According to one embodiment of the present invention of FIG. 7, the blocking member may be present on the surface of the second cover (52).

[0143] Additionally, the blocking member may be made of the same material as the second cover (52) and may be integrated with the second cover (52).

[0144] The inclusion of such a blocking member changes the gap (2) into a protruding shape. For example, if the gap is formed to extend longward toward the inside of the housing (10), the size of the gap (2) can be implemented in a form that gradually narrows as it moves away from the slot. If the size of the gap (2) is reduced, the sound signal injected into the gap (2) is not deeply injected but is immediately reflected, so the degree of reinforcement / cancellation is not great.

[0145] Conventionally, the panel member (20) and the first cover (51) have a flat structure, so that a gap (2) of a certain size or larger is created between the panel member (20) and the first cover (51), and a resonance phenomenon occurs at a specific frequency due to this gap (2). This resonance causes a sudden peak at a specific frequency, and as a result, energy becomes unbalanced, causing a dip. Here, the peak refers to a point in the frequency response curve where a specific frequency is output louder than other frequencies due to the speaker design, the characteristics of the enclosure, environmental factors, etc., and the dip refers to a point in the frequency response curve where the output of a specific frequency decreases due to the speaker design, the characteristics of the enclosure, environmental factors, etc.

[0146] Here, peaks can be compensated for through signal processing, but dips are difficult to compensate for, requiring a separate tweeter. This structural issue is a major factor in increasing the production cost of electronic devices that include slot-loading loudspeakers (SLLs).

[0147] The gap (2) between the panel member (20) and the first cover (51) can be reduced by convexly protruding the surface of the first cover (51) toward the panel member (20) due to the inclusion of the blocking member. As this gap (2) is reduced, the sound signal emitted from the first speaker unit (31) can be radiated through the gap between the first cover (51) and the panel member (20) and thereby reduce the indirectly radiated sound signal reflected. As the indirectly radiated sound signal is reduced, the reinforcement and / or destructive interference with the directly radiated sound signal is reduced, and the sound quality of the speaker device (1) can be improved. In addition, since there is no need to arrange a separate tweeter, the production cost of the electronic device can be reduced.

[0148] This is not limited to the first cover (51), and can be applied to the second cover (52) as well. Specifically, the surface of the second cover (52) protrudes convexly toward the panel member (20) due to the inclusion of the blocking member, thereby reducing the gap (2) between the panel member (20) and the second cover (52).

[0149] According to one embodiment of the present invention of FIG. 8, the surface of the first cover (51) in the speaker device (1) has a flat shape, and a blocking member (90) may be further included on the front surface of the first cover (51).

[0150] The blocking member (90) may be made of a different material from the first cover (51).

[0151] For example, the material of the blocking member (90) may be polyester fiber, compressed fiber, polyurethane foam, fiberglass, cellulose, or cotton fiber.

[0152] The blocking member (90) may absorb the sound signal emitted from each speaker unit (31, 41) and may prevent the sound signal emitted from each speaker unit (31, 41) from being transmitted to the center of the housing (10). In Fig. 8, the blocking member (90), which is present on the surface of the cover (51, 52) and protrudes toward the panel member (20), may or may not be in contact with the panel member (20).

[0153] According to one embodiment of the present invention of FIG. 9, the surface of the first cover (51) in the speaker device (1) may have a flat shape, and the lower surface of the panel member (20) may have a convex shape protruding in the direction of the first cover (51) due to the inclusion of the blocking member (90). As the lower surface of the panel member (20) protrudes, the size of the gap may vary according to the distance, as in FIG. 7.

[0154] In Fig. 9, the blocking member (90) may be manufactured integrally with the same material as the panel member (20), or may be manufactured with a different material on the rear surface of the panel member (20).

[0155] For example, the material of the blocking member (90) may be polyester fiber, compressed fiber, polyurethane foam, fiberglass, cellulose, or cotton fiber.

[0156] The blocking member (90) can absorb the sound signal emitted from each speaker unit (31, 41) and prevent the sound signal emitted from each speaker unit (31, 41) from penetrating into the center of the housing (10).

[0157] According to one embodiment of the present disclosure, the blocking member (90) is formed in a convexly protruding shape. However, the present invention is not limited thereto, and the shape of the vertically cut cross-section may have various shapes, such as a rectangle or a trapezoid.

[0158] In Fig. 9, the blocking member (90) that exists on the rear surface of the panel member (20) and protrudes toward the cover (51, 52) may or may not come into contact with the cover (51, 52).

[0159] According to one embodiment of the present invention of FIG. 10, the surface of the first cover (51) may be in a shape that protrudes convexly toward the panel member (20) due to the inclusion of the blocking member, and the rear surface of the panel member (20) may be in a shape that protrudes convexly toward the first cover (51) due to the inclusion of the blocking member.

[0160] According to one embodiment of the present invention of FIG. 10, the blocking member present in the first cover (51) can be integrated with the first cover (51), and the blocking member present in the panel member (20) can be integrated with the panel member (20) and can be made of the same material.

[0161] However, this is not limited to this, and the blocking member present in the first cover (51) and the blocking member present in the panel member (20) may be made of different materials from the first cover (51) and the panel member (20), respectively.

[0162] According to one embodiment of the present invention of FIG. 11, the surface of the first cover (51) can be convexly protruded toward the panel member (20) due to the inclusion of the blocking member, and the blocking member (90) arranged on the rear surface of the panel member (20) can be convexly protruded toward the first cover (51).

[0163] In Fig. 11, both the blocking member present on the surface of the first cover (51) and the blocking member (90) arranged on the rear surface of the panel member (20) protrude convexly, thereby further reducing the gap (2) between the housing (10) and the panel member (20) or making it difficult for an acoustic signal to propagate.

[0164] In Fig. 11, the surface of the first cover (51) and the blocking member (90) arranged on the rear side of the panel member (20) are not in contact with each other, but are arranged in a spaced state.

[0165] In Fig. 11, the blocking member present on the surface of the cover (51, 52) may or may not be in contact with the blocking member (90) present on the rear surface of the panel member (20).

[0166] In Fig. 11, the blocking member (90) may be a sound absorbing material.

[0167] In Fig. 11, the sound-absorbing material may be Acoustic Meta Material (AMM).

[0168] In Fig. 12, the speaker device (1) may include at least one first blocking member (91) on the front surface of the plate (60) and at least one second blocking member (92) on the rear surface of the panel member (20).

[0169] In FIG. 12, according to one embodiment of the present disclosure, the first blocking member (91) and the second blocking member (92) may be arranged spaced apart from each other. Alternatively, they may be described in a zigzag shape, a bent shape, and a meander shape.

[0170] Specifically, a plurality of first blocking members (91) are arranged on the front surface of the valve (60) and the first cover (51), and a plurality of second blocking members (92) are arranged on the rear surface of the panel member (20), so that a meander-shaped passage can be formed by a plurality of protruding protrusions.

[0171] According to one embodiment of FIG. 12, the size or shape of the cross-section of the gap (2) between the housing (10) and the panel member (20) can be changed depending on the position by the first blocking member (91) and / or the second blocking member (92).

[0172] According to one embodiment of the present disclosure, at least one of the first blocking member (91) and the second blocking member (92) may be a sound-absorbing material.

[0173] The sound-absorbing material can be polyester fiber, compressed fiber, polyurethane foam, fiberglass, cellulose, or cotton fiber.

[0174] In Fig. 12, the sound-absorbing material can absorb indirectly radiated sound signals to prevent interference with sound signals directly radiated from the first and second speaker units (31, 32).

[0175] According to another embodiment of the present disclosure in FIG. 12, one of the first blocking member (91) and the second blocking member (92) may be a sound-absorbing material, and the other may be made of the same material as the panel member (20) and / or the first cover (51).

[0176] In Fig. 12, the blocking member (91) present on the surface of the cover (51, 52) may or may not be in contact with the panel member (20) or the blocking member (92) present on the rear surface of the panel member (20).

[0177] In Fig. 12, the blocking member (92) present on the rear surface of the panel member (20) may or may not be in contact with the cover (51, 52) or the blocking member (92) or the valve (60) present on the surface of the cover (51, 52).

[0178] Fig. 13 is a rear perspective view showing the rear surface of the speaker device (1).

[0179] In Fig. 13, the housing (10) has two third speaker units (33) arranged on the back surface.

[0180] The expression of the third speaker unit (33) may be expressed differently as a rear speaker unit.

[0181] The two third speaker units (33) can be arranged symmetrically with respect to the center.

[0182] According to one embodiment of the present invention, the third speaker unit (33) is larger in size than the first speaker unit (31) and the second speaker unit (32), and may be 5 inches in size.

[0183] The third speaker unit (33) can emit an acoustic signal toward the rear of the housing (10), and thus can provide rich sound together with the speaker unit placed toward the front.

[0184] The third speaker unit (33) can be of various types, such as a tweeter, a woofer, a mid-range, and a full-range, depending on the frequency range.

[0185] By using multiple speaker units (the first speaker unit (31), the second speaker unit (32), and / or the third speaker unit (33)), multiple frequency ranges (high frequency to low frequency) can be separately reproduced for each speaker unit.

[0186] This allows each speaker unit to be optimized for a specific frequency band, producing clearer, more accurate sound. It also reduces distortion and improves sound quality.

[0187] Additionally, durability can be improved by using multiple speaker units (first speaker unit (31), second speaker unit (32) and / or third speaker unit (33)).

[0188] Specifically, since each speaker unit (31, 32, 33) does not cover the entire frequency band, the burden on one unit is reduced, which can extend the life of the entire system.

[0189] Additionally, by using multiple speaker units (first speaker unit (31), second speaker unit (32) and / or third speaker unit (33)), individual tuning functions can be achieved.

[0190] Specifically, the treble, midrange, and bass of each of the plurality of speaker units (the first speaker unit (31), the second speaker unit (32), and / or the third speaker unit (33)) can be separately adjusted to enhance or reduce specific frequency bands. This allows for optimizing sound for various environments.

[0191] According to one embodiment of the present disclosure, the first speaker unit (31) may be a tweeter responsible for a high-frequency sound range, the second speaker unit (32) may be a mid-range speaker responsible for a middle sound range, and the third speaker unit (33) may be a woofer responsible for a low-frequency sound range.

[0192] The housing (10) can be hung on a structure such as a wall or partition through the hole (400).

[0193] In Fig. 13, the operating unit (500) can be placed on the rear side of the left and / or right side of the housing (10).

[0194] In Fig. 13, the control unit (500) may include a button for adjusting the volume of the speaker device (1), a power button, or various other buttons.

[0195] In Fig. 13, the operating unit (500) may further include an LED.

[0196] In Fig. 13, the discharge unit (600) can be installed in the central portion of the housing (10). The discharge unit (600) is configured to discharge internal heat of the speaker device (1).

[0197] The discharge portion (600) may have a mesh shape.

[0198] The exhaust unit (600) can lower the internal temperature when the speaker device (1) is operated for a long time.

[0199] The support (200) can be placed on the rear side of the back of the speaker device (1).

[0200] According to one embodiment of the present disclosure, a support plate (not shown) can be fixed to a support member (200). Through this, the speaker device (1) can be placed on various floor surfaces such as a desk.

[0201] In the above-described speaker device (1), each speaker unit includes a slot for outputting an audio signal through an exposed area (100). If a user is in front of the speaker unit (1), the slot may be exposed to the user's view, which may be unsightly. In addition, foreign substances may enter the speaker unit through the slot. To prevent this, a mesh cover may be further included to entirely cover the exposed area (100). The mesh cover may be made of a fabric material, but is not necessarily limited thereto, and may be made of various forms, such as a metal material or a plastic material.

[0202] Each of the components described in this document may be composed of one or more components, and the names of the components may vary depending on the type of electronic device.

[0203] Although various embodiments of the present disclosure have been individually described above, each embodiment does not necessarily have to be implemented alone, and the configuration and operation of each embodiment may be implemented in combination with at least one other embodiment.

[0204] In addition, although various embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and various modifications can be made by a person having ordinary skill in the art to which the present invention pertains without departing from the gist of the present disclosure claimed in the claims, and such modifications should not be understood individually from the technical idea or prospect of the present disclosure.
