Description

Technical Field

[0001] This disclosure relates to a loudspeaker device having a slotted loudspeaker unit. Background Technology

[0002] A loudspeaker is a device that converts electrical signals into acoustic signals and radiates those signals.

[0003] Typically, a loudspeaker device consists of a box-shaped housing with a spatial arrangement and a loudspeaker unit that generates acoustic signals as a diaphragm vibrates. The loudspeaker unit can generate acoustic signals across a wide range of sound frequencies, covering low to high frequencies.

[0004] As electronic devices become thinner, the size of the corresponding loudspeakers needs to be reduced, so slotted loudspeakers (SLL) have been developed, in which the acoustic signal spinnerets are designed in the form of slots. Summary of the Invention

[0005] Technical issues Recently, in order to enhance aesthetics, electronic devices have been developed and distributed in which a panel for decorative purposes is incorporated into the front surface of a slotted speaker.

[0006] In this electronic device, a portion of the acoustic signal output through the slot may be reflected from the back or interior of the panel, potentially interfering with the acoustic signal directly output through the slot. Therefore, amplitude spectrum distortion of the acoustic signal occurs, and consequently, sound quality is degraded.

[0040] In the following description, with reference to the accompanying drawings, a loudspeaker device according to various embodiments is specifically described.

[0041] Figure 1 This is a perspective view of a loudspeaker device according to an embodiment. (Refer to...) Figure 1 The speaker device 1 may include a housing 10, a panel component 20, etc.

[0042] Housing 10 refers to the main body of speaker device 1. Housing 10 can be described differently by various terms such as packaging, box, and main body.

[0043] The housing 10 includes various electronic devices, batteries, etc. housed therein, and serves to protect these devices. The housing 10 can be implemented in various forms, such as an upright form for standing the housing 10 upright on the bottom, a form for mounting on a wall, and a form for hanging from the ceiling by a wire.

[0044] exist Figure 1 The image shows a housing 10 implemented in a square shape, but it is not limited to this and can have various shapes (such as circular and polygonal shapes).

[0045] Panel member 20 may be formed on the front surface of housing 10.

[0046] The panel component 20 can be made of various materials such as PVC, acrylic, polycarbonate and other plastic materials, glass materials, rubber materials, wood materials and metal materials.

[0047] The panel member 20 can be implemented in a detachable form from the housing 10. Images can be drawn on the front surface of the panel member 20, or a display can be included therein, thus displaying images. Therefore, the user can use the speaker device 1 with the panel member 20 attached like a picture frame. If the panel member 20 is designed to resemble a picture frame, the user can freely replace it according to their preferences. If the panel member 20 includes a display, the user can freely change the displayed image according to their preferences. Image changes can be transmitted to the panel member 20 or the speaker unit using a portable storage device (such as a USB memory stick), or wirelessly or wiredly connected to the panel member 20 or the speaker unit via a mobile phone, tablet, PC, laptop, etc. Furthermore, image changes can be downloaded via a server device.

[0048] If the panel member 20 is attached to the front surface, it may be difficult to output acoustic signals along the direction of the front surface of the speaker device 1. If the speaker unit is formed in the direction of the front surface of the speaker device 1, the panel member 20 covers the front or front side of the speaker device 1, and therefore a part of the speaker unit is obscured. Therefore, the thickness of the panel member 20 can be made very thin so that the acoustic signals radiated from the speaker unit can be well transmitted to the outside.

[0049] According to at least one embodiment of this disclosure, the panel member 20 may be spaced apart at a position on the front side of the slotted speaker such that the opening is not obstructed. Furthermore, an exposed area 100 may be formed between the edge of the housing 10 and the edge of the panel member to transmit acoustic signals output from the opening to the outside.

[0050] The exposed area 100 may be referred to in various ways (such as boundary area, exposed area, penetrating area and gap area).

[0051] Furthermore, according to at least one embodiment of this disclosure, the panel member 20 is connected with reference to the center of the speaker device 1 (i.e., the center of the housing 10). If the area of ​​the panel member 20 is smaller than the area of ​​the housing 10, at least one of the upper edge, lower edge, left edge, or right edge may be exposed. Figure 1 The diagram shows a case where the entirety of the top, bottom, left, and right edges constitutes the exposed area 100. The slot-mounted loudspeaker can be positioned at the rear or back of the exposed area 100. Specifically, an opening for transmitting acoustic signals radiated from the slot-mounted loudspeaker to the outside is provided on the rear surface of the exposed area 100. Therefore, even if a portion of the loudspeaker unit is obscured by the panel member 20, acoustic signals can still be effectively transmitted to the user through the opening formed in the exposed area 100 that is not obscured by the panel member 20.

[0052] exist Figure 1 In this case, a gap must be formed between the housing 10 and the panel member 20.

[0053] In conventional loudspeaker equipment, even if the opening is located in the exposed area 100, a portion of the acoustic signal output through the opening can still flow into the interior of the gap. This inflowing acoustic signal is transmitted into the gap, reflected, and then exists, resulting in the distortion and / or destruction of both the acoustic signals directly radiated from the loudspeaker unit and those indirectly radiated from the loudspeaker unit. Consequently, the amplitude spectrum of the acoustic signal may be distorted, and the sound quality may be degraded.

[0054] Specifically, constructive interference occurs when the directly output acoustic signal and the acoustic signal reflected from inside the gap meet in the same phase or aligned phase; conversely, destructive interference occurs when they meet in opposite phases.

[0055] If constructive interference occurs, the amplitudes of the individual acoustic signals are added together, and thus an acoustic signal with a larger amplitude than the volume set by the user is transmitted; if destructive interference occurs, the volume of the acoustic signal can be reduced or almost disappeared.

[0056] Figure 2 This is a schematic diagram of the cross-sectional structure of a loudspeaker device 1 according to various embodiments.

[0057] according to Figure 2 The loudspeaker device 1 includes a housing 10, a slotted loudspeaker disposed inside the housing, and a panel component 20.

[0058] Slot-mounted loudspeakers are specially designed audio devices that emit sound through a narrow slot (i.e., opening 41). Primarily, this allows for fine control over the direction of sound and improvement in sound quality within specific frequency bands. Furthermore, by using a narrow slot and reducing the size of the loudspeaker itself, acoustic design can be optimized and space utilization can be enhanced.

[0059] according to Figure 2 The illustration shows two slotted speakers arranged symmetrically at the edges of both sides of the housing 10. However, this disclosure is not limited to this, and only one slotted speaker may be arranged on one side, or multiple slotted speakers (instead of one slotted speaker) may be arranged on both sides.

[0060] The slotted loudspeaker may be constructed with a loudspeaker unit 31, an opening 41, a cover 51, etc. The opening 41 is formed to penetrate the cover 51 and can output acoustic signals generated from the loudspeaker unit 31. When using a slotted loudspeaker, even if the panel member 20 is attached to the front of the housing 10, acoustic signals can be output through the exposed area between the panel member 20 and the housing 10.

[0061] Reference Figure 1 and Figure 2 The diagram shows an exposed area 100 formed between the edge of the panel member 20 and the edge of the housing 10, but the exposed area 100 can vary depending on the connection location, shape, etc., of the panel member 20. For example, the exposed area can be formed in the central portion or other internal region, rather than around the edge of the housing 10. The panel member 20 can be positioned so that the exposed area does not obstruct the acoustic signals output through the opening 41. Figure 1 and Figure 2 The opening 41 is shown to be disposed around the edge of the housing 10, and the exposed area 100 is formed on the front side of the opening 41.

[0062] The panel member 20 is separately provided at a position on the front side of the slot-mounted speaker where the opening 41 is not blocked, and thus a gap is formed between the cover 51 and the panel member 20. At least a part of the acoustic signal output through the opening 41 can flow into the interior of the gap. Therefore, according to at least one embodiment of the present disclosure, the speaker device 1 includes at least one blocking member 90 for preventing the acoustic signal from flowing into the interior of the gap. In the present disclosure, blocking should be interpreted as meaning not only completely preventing inflow but also minimizing the ratio of inflow. The blocking member 90 can be manufactured in various forms according to various embodiments of the present disclosure. The blocking member 90 can be formed on at least one of the cover 51 or the panel member 20, but can also be formed on various other components.

[0063] Figure 2 It is shown that the blocking member 90 is formed on the surface of the cover 51. The blocking member 90 can have a structure integrated with the cover 51 using the same material as the cover 51, and can also have a structure separately manufactured using a material different from the material of the cover 51 and attached or bonded to the cover 51.

[0064] The blocking member 90 can be manufactured in a form for reducing the size of the gap. According to an embodiment of the present disclosure, the blocking member 90 can be provided in a form protruding in the direction of the panel member 20. Here, the blocking member 90 can be provided in a form contacting the panel member, and can also be provided in a form not contacting the panel member.

[0065] In Figure 2 According to an embodiment of the present disclosure, the width d1 between the panel member 20 and the blocking member 90 can be narrower than the width d2 between the panel member 20 and the cover 51. Therefore, it can be 0 < d1 < d2. Due to the above, the indirect reflected sound reflected after the sound emitted from the opening 41 flows into the interior of the gap can be minimized or removed, and thus the sound quality can be improved.

[0066] In Figure 2 According to an embodiment of the present disclosure, the blocking member 90 can have a rectangular parallelepiped shape.

[0067] In Figure 2 According to an embodiment of the present disclosure, the blocking member 90 can have a convex dome shape. However, the present disclosure is not limited thereto, and it can have various shapes (such as a pyramid shape).

[0068] In Figure 2In an embodiment of this disclosure, an exposed area 100 may be formed between the edge of the housing 10 and the edge of the panel member 20 to transmit acoustic signals output from the opening 41 to the outside. Furthermore, at least one of the cover 51 or the panel member 20 may include at least one blocking member 90 for preventing acoustic signals output through the opening 41 from flowing into the gap 2.

[0069] exist Figure 2 In an embodiment of the present disclosure, the opening 41 is formed as a through cover 51 and is capable of outputting acoustic signals generated from the speaker unit 31.

[0070] exist Figure 2 In embodiments of this disclosure, an auxiliary member (not shown) may also be included on at least one surface of the panel member 20, the cover 51, or the blocking member 90. Here, the auxiliary member (not shown) may be an acoustic metamaterial (AMM). However, this disclosure is not limited thereto, and the auxiliary member (not shown) may be made of a variety of different materials.

[0071] Figure 3 It is magnification Figure 1 The view of part "B".

[0072] Figure 3 The enlarged view shows the state in which the panel component 20 is attached to the housing 10. Figure 3 Two slotted loudspeakers are shown positioned on the left edge region, and two loudspeaker units 31 and 32 are disposed within the two slotted loudspeakers. For ease of description, in the following description, one of the two loudspeaker units 31 and 32 will be referred to as the first loudspeaker unit 31, and the other as the second loudspeaker unit 32. However, this disclosure is not limited thereto, and the first loudspeaker unit 31 may be referred to as a loudspeaker unit or a main loudspeaker unit, and the second loudspeaker unit 32 may be referred to as an additional loudspeaker unit or an auxiliary loudspeaker unit. Both loudspeaker units 31 and 32 may be implemented as slotted loudspeaker units that output acoustic signals through openings. For ease of description, the opening of the first loudspeaker unit 31 will be referred to as the first opening 41, and the opening of the second loudspeaker unit 32 will be referred to as the second opening 42.

[0073] However, openings 41 and 42 are not limited to these descriptions and can be replaced by various descriptions such as slots, holes, gaps, radiating areas, and sound-producing components.

[0074] exist Figure 3 In the middle, the first opening 41 is formed on the front surface of the first speaker unit 31.

[0075] exist Figure 3In this configuration, the dimensions of the panel member 20 can be configured to be smaller than the dimensions of the front surface of the housing 10. Therefore, if the panel member 20 is attached to the housing 10 with the center of the housing as a reference, the exposed area 100 can be configured between the housing 10 and the panel member 20.

[0076] exist Figure 3 In an embodiment of this disclosure, the panel member 20 may be shaped as a square to match the shape of the housing 10.

[0077] However, this disclosure is not limited thereto, and according to another embodiment, the length and width-to-height ratio of the panel member 20 is formed to be the same as the length and width-to-height ratio of the housing 10, wherein it is possible to join the panel member 20 and the housing 10 in a rotated state at a certain angle to expose a portion of the housing 10 when joining them. Furthermore, it is possible to align and join the panel member 20 and the housing 10 equally, wherein a portion of the panel member 20 is cut out to expose a portion of the housing 10 (e.g., a corner).

[0078] exist Figure 3 In the middle, a portion of the acoustic signal emitted from the first speaker unit 31 can be directly emitted through the first opening 41 and the exposed area 100.

[0079] Another portion of the acoustic signal emitted through the first opening 41 can be emitted into the gap between the panel member 20 and the housing 10, rather than into the exposed area 100.

[0080] Here, acoustic signals emitted into the gap can be reflected and returned from the rear surface of the panel member 20 and / or the inner surface of the housing 10.

[0081] The reflected and returned acoustic signals may interfere with the acoustic signals emitted directly through the first opening 41 and the exposed area 100.

[0082] Through the above, acoustic signals can be constructed and / or destroyed, and sound quality can be degraded.

[0083] According to various embodiments of this disclosure, it is possible to make various modifications to the gap between the speaker unit and the panel member, and the gap can vary depending on the distance between the cover and the panel member 20. Based on the above, acoustic signals emitted from the speaker unit are prevented from being transmitted deep into the gap, thereby greatly reducing the construction / destruction ratio compared to acoustic signals emitted directly through the opening.

[0084] Figure 4 It is shown in Figure 1 An exploded perspective view showing the state of the separated housing 10 and panel component 20.

[0085] based on Figure 4 This allows for a more detailed understanding of the configuration of the housing 10.

[0086] The cover 51 is an assembly that covers 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 on the first cover 51.

[0087] Furthermore, the second cover 52 is an assembly that covers the second speaker unit 32. A second opening 42 may be formed on the second cover 52. Unlike the first opening 41, the second opening 42 may be implemented in the form of multiple slots, wherein an opening is divided into multiple slots by at least one partition wall. Figure 3 This shows the state where the second opening 42 is divided into three openings.

[0088] exist Figure 4 The diagram shows that 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 larger than the size of the first cover 51. However, this disclosure is not limited to this, and the first speaker unit 31 and the second speaker unit 32 can be implemented with the same size.

[0089] In addition, Figure 4 The diagram shows multiple first speaker units 31 disposed at the center portions of the left and right edges of the upper, lower, left, and right edges of the housing 10, and multiple second speaker units 32 disposed at positions spaced apart from the first speaker units 31 along the left and right edges of the housing (in... Figure 3 In the case of the upper side), the number, placement, size, shape, etc. of the first speaker unit 31 and the second speaker unit 32 can be changed differently.

[0090] The first speaker unit 31 and the second speaker unit 32 can be implemented in different speaker forms.

[0091] For example, the first speaker unit 31 may be a midrange speaker responsible for the midrange frequency range, and the second speaker unit 32 may be a tweeter responsible for the high-frequency frequency range.

[0092] According to another embodiment, the first speaker unit 31 may be a tweeter responsible for the high-frequency sound range, and the second speaker unit 32 may be a midrange speaker responsible for the mid-frequency range.

[0093] According to another embodiment, speaker unit 31 and speaker unit 32 may be configured as at least one of a tweeter, a midrange speaker, or a woofer.

[0094] The first speaker unit 31 and the second speaker unit 32 are located on the rear side of the panel member 20. Therefore, if the acoustic signal is output as is, it cannot be well transmitted to the outside through the panel member 20. To prevent the above problem, covers 51 and 52 including openings 41 and 42 are provided, wherein the openings 41 and 42 output the acoustic signal radiated from the first speaker unit 31 and the second speaker unit 32 to the outside through the exposed area 100. The sound quality of the bass acoustic signal output from the speaker device 1 can be enhanced by the first cover 51 and / or the second cover 52, and unwanted noise or distortion can be reduced.

[0095] Furthermore, through the first cover 51 and / or the second cover 52, the speaker device 1 has the effect of accurately reproducing sound even at lower frequencies.

[0096] Furthermore, through the first cover 51 and / or the second cover 52, the speaker device 1 can extend its frequency range and transmit sound effectively.

[0097] Furthermore, the speaker units 31, 32 can be housed inside the electronic product (e.g., housing 10) via the first cover 51 and / or the second cover 52, thus making efficient use of space.

[0098] The materials of cover 51 and / or second cover 52 may vary depending on the purpose. Specifically, they may be configured from a variety of materials such as plastic, metal, wood, and fabric.

[0099] Here, plastic materials are lightweight and easy to process. Metals excel in durability and have less impact on sound quality. Wood can be used when design is critical. Fabrics are good at acoustic permeability, thus protecting the speaker units without compromising sound quality.

[0100] Fastening components 70 may be formed on the inside of each edge of the front surface of the housing 10, and a plate 60 may be formed at the center of the front surface of the housing 10.

[0101] The fastening component 70 is an assembly used to attach the panel member 20 to and / or detach it from the housing 10. Through the above, the panel member 20 can be joined or separated.

[0102] According to embodiments of the present disclosure, the fastening member 70 may be configured as a circular groove or an uneven structure. However, the present disclosure is not limited thereto; the fastening member 70 may be configured as a polygonal groove and may be configured in the form of, for example, a magnet.

[0103] According to embodiments of this disclosure, fastening members 70 may be provided one after another at each edge of the front surface of the housing 10.

[0104] Fastening members (not shown) may be formed at each edge of the rear surface of the panel member 20. The fastening members may be configured as protruding or non-protruding structures. The fastening members (not shown) may be formed as protruding structures, and if the fastening member 70 is formed as a recess, the fastening members may be fastened by insertion into the fastening member 70. Through the engagement of the fastening members (not shown), the panel member 20 may be secured to the housing 10.

[0105] Although not shown in the accompanying drawings, according to another embodiment, the fastening member 70 may be configured as one of the central portions of the membrane 60.

[0108] According to embodiments of the present disclosure, the first speaker unit 31 may be circular, and the second speaker unit 32 may be elliptical, such that the height of the second speaker unit 32 is longer than the width of the second speaker unit 32.

[0109] However, this disclosure is not limited thereto, and the first speaker unit 31 and the second speaker unit 32 may have various shapes (such as square shapes and polygonal shapes).

[0110] Sound can be generated by converting electrical signals into acoustic signals through the first speaker unit 31 and the second speaker unit 32. The internal configuration of the first speaker unit 31 and the second speaker unit 32 can use various types such as tweeters, woofers, midrange speakers and full-range speakers according to the frequency domain of the acoustic signals.

[0111] Here, a woofer is a speaker specifically designed for low-frequency sounds (such as deep bass), a midrange speaker is a speaker specifically designed for the mid-range frequency band, and a tweeter is a speaker specifically designed for high-frequency sounds. Furthermore, a full-range speaker is a speaker designed to cover the entire range from low to high frequencies.

[0112] The diaphragm 60 can be configured as an internal electronic component in the central internal region of the protective housing 10, excluding the exposed area 100. The electronic components inside the speaker can consist of a battery, a transducer, etc.

[0113] Reference Figure 4 and Figure 5 The membrane 60 can have a square shape.

[0114] However, this disclosure is not limited thereto, and the membrane 60 may have various shapes (such as circular and polygonal shapes).

[0115] exist Figure 5 In this case, the fixing member 61 can be located between the housing 10 and the plate 60 to fix the plate 60 to the housing 10.

[0116] Figure 5 Only a portion is shown, but the fixing member 61 can be provided at each edge of the front surface of the membrane 60.

[0117] The fixing component 61 may be composed of bolts, screws, or other threaded fasteners.

[0118] exist Figure 6 In this context, the slotted loudspeaker has a structure in which the transducer is embedded in the housing.

[0119] A transducer (not shown) is disposed inside the first speaker unit 31, and the housing may include a first opening 41, a first cover 51, etc.

[0120] A transducer (not shown) generates acoustic signals through the vibration of a diaphragm. The transducer (not shown) can convert acoustic signals into electrical signals and can generate acoustic signals for a variety of sound ranges, from low-frequency to high-frequency.

[0121] exist Figure 6 In this design, the first cover 51 has a mesh shape. The first cover 51 can be positioned at a certain distance on the front surface of the first speaker unit 31. When viewed vertically from top to bottom, the central portion of the mesh portion of the first cover 51 corresponds to the central portion of the first speaker unit 31.

[0122] exist Figure 6 In the middle, the first opening 41 can be set next to the first cover 51.

[0123] exist Figure 6 In this embodiment, the first opening 41 may have a shape that exposes a portion of the first speaker unit 31. However, this disclosure is not limited thereto, and the cross-section of the first opening 41 may have various shapes (such as rectangular, elliptical, and circular shapes).

[0124] Figures 7 to 12 It shows along Figure 1A diagram showing the section cut along axis A-A'. Figures 7 to 12 In this device, the loudspeaker device 1 may be constructed from a panel member 20, a first loudspeaker unit 31, a first opening 41, a first cover 51, a blocking member 90, a diaphragm 60, a fastening member 70, and a support member (not shown).

[0125] Specifically, in Figures 7 to 12 In this configuration, a first slotted cover 51 is disposed on the outside of the diaphragm 60, a first speaker unit 31 is disposed on the rear side of the first slotted cover 51, and a panel member 20 is disposed on the front side of the diaphragm 60. For example... Figures 7 to 12 As shown, a gap 2 is formed between the first cover 51 and the panel member 20.

[0126] exist Figures 7 to 12 In this configuration, a support (not shown) serves to support the components of each electronic device so that they are set to conform to standards and are not shaken.

[0127] The support (not shown) can be constructed from a variety of materials, such as plastics, metals, ceramics and composites.

[0128] The housing can be constructed using a first cover 51 on the front surface of the first speaker unit 31, a support member (not shown) supporting the rear surface of the first speaker unit 31, etc.

[0129] exist Figures 7 to 12 The diagram shows that the cross-sections of the first cover 51 and the blocking members 90, 91, and 92 are convex, but this disclosure is not limited to this. The cross-sections may not only have a semi-circular shape, but also a rectangular shape, a trapezoidal shape, etc.

[0130] exist Figures 7 to 12 In the process, the first cover 51 and the blocking members 90, 91, 92 may also include auxiliary members (not shown).

[0131] exist Figures 7 to 12 In embodiments of this disclosure, the auxiliary component (not shown) may be an acoustic metamaterial (AMM). Figures 7 to 12 In this case, the auxiliary components (not shown) may cover the surfaces of the covers 51 and 52 and the entire rear surface of the panel component 20, or may only cover a portion of these surfaces.

[0132] exist Figure 7 In an embodiment of this disclosure, the blocking member may be present on the surface of the first cover 51.

[0133] Furthermore, the blocking member can be integrated with the first cover 51 using the same material.

[0134] exist Figure 7In an embodiment of this disclosure, the blocking member may be present on the surface of the second cover 52.

[0135] Furthermore, the blocking member can be made of the same material as the second cover 52 and can be integrated with the second cover 52.

[0136] The inclusion of this blocking member creates a protruding shape, thus altering the gap 2. As an example, if the gap 2 is formed to extend into the interior of the housing 10, the size of the gap 2 can be implemented such that it gradually narrows as it moves away from the position near the slot. If the size of the gap 2 is reduced, acoustic signals inserted into the gap 2 may not be inserted deeply and may be directly reflected and exited, thus the degree of construction / damage may not increase.

[0137] Conventionally, the panel member 20 and the first cover 51 may have a flat structure, creating a gap 2 of a certain size or larger between the panel member 20 and the first cover 51, and thus, resonance occurs at a specific frequency due to this gap 2. This resonance results in a sudden peak at the specific frequency, and therefore, energy imbalance and valleys appear. Here, a peak refers to a point where the output of a specific frequency is greater than other frequencies in the frequency response curve due to the speaker design, housing characteristics, environmental factors, etc., and a valley refers to a point where the output of a specific frequency is reduced in the frequency response curve due to the speaker design, housing characteristics, environmental factors, etc.

[0138] However, while peak values ​​can be compensated for through signal processing, valley values ​​are difficult to compensate for, thus requiring a separate high-frequency loudspeaker. This structural problem is a major reason for the increased production cost of electronic devices that include slot-mounted loudspeakers (SLL).

[0139] Because of the inclusion of a blocking member, the surface of the first cover 51 protrudes in the direction of the panel member 20, thereby reducing the gap 2 between the panel member 20 and the first cover 51. Since the gap 2 is reduced, acoustic signals emitted from the first speaker unit 31 are radiated through the gap between the first cover 51 and the panel member 20, thereby reducing reflected indirect radiated acoustic signals. Because the indirect radiated acoustic signals are reduced, constructive and / or destructive interference with directly radiated acoustic signals can be reduced, and the sound quality of the speaker device 1 can be improved. Furthermore, since a separate high-frequency speaker is not required, the production cost of the electronic device can be reduced.

[0140] This is not limited to the first cover 51, but can also be applied to the second cover 52 in the same manner. Specifically, due to the inclusion of a blocking member, the surface of the second cover 52 protrudes to bulge in the direction of the panel member 20, thereby reducing the gap 2 between the panel member 20 and the second cover 52.

[0141] exist Figure 8 In an embodiment of the present disclosure, the surface of the first cover 51 in the speaker device 1 has a flat shape, and the blocking member 90 may be further included on the front surface of the first cover 51.

[0143] For example, the material of the blocking member 90 can be polyester fiber, compressed fiber, polyurethane foam, glass fiber, cellulose, cotton fiber, etc.

[0144] The blocking member 90 absorbs acoustic signals emitted from each speaker unit 31, 41 and prevents acoustic signals emitted from each speaker unit 31, 41 from penetrating the central portion of the housing 10. Figure 8 In the middle, the blocking member 90, which exists on the surface of the cover 51, 52 and is provided in a form that protrudes in the direction of the panel member 20, can contact the panel member 20 and can not contact the panel member 20.
