Referring to FIGS. 6 to 8B, according to one embodiment, the speaker (370) may include a diaphragm (371), a coil (or voice coil) (373), a suspension (372), a plate (374), a frame (375), a magnetic member (376), and / or a yoke (377).
[0088] In one embodiment, the first support structure (361) may include a first portion (361a) and a second portion (361b). In one embodiment, the first portion (361a) of the first support structure (361) may form a side wall structure disposed around the speaker (370). For example, the first portion (361a) may surround at least a portion of the speaker (370). In one embodiment, the first portion (361a) may be formed to surround at least a portion of an acoustic space (A1) between the first speaker cover (362) and the speaker (370) (e.g., the diaphragm (371)). In one embodiment, the first portion (361a) may be formed to provide an open space (or opening) to lead to a passage (A2) at one side of the acoustic space (A1). For example, the open space may be located on one side facing the first speaker hole (317) (e.g., in the -Y direction) of the acoustic space (A1).
[0089] According to one embodiment, the second part (361b) of the first support structure (361) may be formed to extend from a portion of the first part (361a) toward the first speaker hole (317). For example, the second part (361b) may be substantially positioned between the first speaker hole (317) and the first part (361a). According to one embodiment, a passage (A2) connecting an acoustic space (A1) between the first speaker cover (362) and the speaker (370) (e.g., the diaphragm (371)) and the first speaker hole (317) may be formed on the inside of the second part (361b). In the present disclosure, the first part (361a) and the second part (361b) are only distinguished to describe the first support structure (361), but may be formed integrally with each other. For example, the first portion (361a) may be a part of the first support structure (361), and the second portion (361b) may be the remaining portion of the first support structure (361).
[0090] According to one embodiment, the first speaker cover (362) may be spaced apart from the speaker (370) (e.g., the diaphragm (371)). According to one embodiment, at least a portion of the first speaker cover (362) may face the speaker (370) (e.g., the diaphragm (371)). For example, the first speaker cover (362) and the diaphragm (371) of the speaker (370) may be spaced apart from each other by a first distance (d1). For example, the first distance (d1) may mean an average value of the gap between the first speaker cover (362) and the diaphragm (371) when the speaker (370) is not in operation.
[0091] In one embodiment, the second support structure (363) can be connected to a portion of the first support structure (361) (the first portion (361a) and / or the second portion (361b)) and the second speaker cover (364). For example, the second support structure (363) can be disposed around the periphery of the second speaker cover (364). For example, the second support structure (363) can be connected to or integrally formed with at least a portion of an edge of the yoke (377). In one embodiment, the second speaker cover (364) can face the first speaker cover (362) with the speaker (370) therebetween. For example, one surface (e.g., a +Z direction surface) of the second speaker cover (364) can face a portion (e.g., a yoke (377)) of the speaker (370). For example, the speaker housing (360) can be formed of various materials. For example, the first support structure (361) and / or the first speaker cover (362) may include rubber, synthetic resin, and / or metal.
[0092] In one embodiment, the step structure (366) may be disposed adjacent to an edge where a portion of the first part (361a) of the first support structure (361) and the first speaker cover (362) come into contact. According to one embodiment, the step structure (366) may be a structure that reflects a portion of the sound output from the speaker (370) toward the first speaker hole (317). For example, the frequency of the sound reflected from the step structure (366) and the frequency of the sound reflected from the first part (361a) where the step structure (366) is disposed may be different. For example, the frequency band of the sound reflected from the first part (361a) where the step structure (366) is disposed may be higher than the frequency band of the sound reflected from the step structure (366).
[0093] In one embodiment, the step structure (366) may be spaced apart from the speaker (370) (e.g., the diaphragm (371) and the suspension (372)). For example, referring to FIG. 7B, the step structure (366) may be spaced apart from the suspension (372) of the speaker (370) by a second distance (d2). For example, the second distance (d2) may mean an average value of the gap between the first speaker cover (362) and the speaker (370) when the speaker (370) is not in operation. According to one embodiment, the step structure (366) may be spaced apart from the diaphragm (371) and the suspension (372) so as to come into contact with the diaphragm (371) or the suspension (372) when the speaker (370) is in operation.
[0094] According to one embodiment, the step structure (366) may be in a shape that protrudes from the surface of the first support structure (361) by a specified distance (e.g., L3 in FIG. 7B). According to one embodiment, the step structure (366) may overlap at least a portion of the suspension (372) without overlapping the diaphragm (371) when looking down at the first speaker cover (362) from above (or when looking in the +Z direction). According to one embodiment, the step structure (366) may include two faces (e.g., a +Z direction face and a -Y direction face) that form a non-zero angle (e.g., 90 degrees) with respect to each other. In the present disclosure, the shape of the step structure (366) may be changed, and for example, the step structure (366) may include three or more continuous faces, may include an entirely curved surface, or may have an irregular shape.
[0095] In one embodiment, the step structure (366) may be a part of the first support structure (361). For example, the step structure (366) may be formed integrally with the first support structure (361) and may be formed or manufactured, for example, by injection molding. In one embodiment, the material of the step structure (366) may be similar to or substantially identical to the material of the first support structure (361). For example, the step structure (366) may be formed of various materials such as rubber, synthetic resin, or metal.
[0096] According to one embodiment, the speaker assembly (305) may further include a cap member (380) positioned to block an end of the passage (A2) of the second portion (361b) of the first support structure (361). For example, the cap member (380) may be formed to prevent foreign substances, such as moisture, from outside the electronic device (101) from entering the speaker housing (360) through the first speaker hole (317). For example, the cap member (380) may include a porous structure, such as a mesh. For example, the cap member (380) may be configured to connect the second portion (361b) of the first support structure (361) to a portion of the housing (310) (e.g., the rear injection structure (324)). For example, the cap member (380) can provide a waterproof structure at the connection between the second portion (361b) of the first support structure (361) and a portion of the housing (310) (e.g., the rear injection structure (324)).
[0097] Referring to FIGS. 6 to 8B, according to one embodiment, the speaker (370) may include a diaphragm (371), a coil (or voice coil) (373), a suspension (372), a plate (374), a frame (375), a magnetic member (376), and / or a yoke (377).
[0098] According to one embodiment, the diaphragm (371) can move linearly back and forth in a direction (Z-axis direction) toward or away from the yoke (377) or the first speaker cover (362) based on the electromagnetic force formed by the coil (373) and the magnetic member (376) and / or the elastic force of the suspension (372). For example, the diaphragm (371) can be in the shape of a flat plate. In the present disclosure, the shape of the diaphragm (371) can be changed. For example, the diaphragm (371) can be in the shape of at least a partial curve, and can include, for example, a sunken area (e.g., a recess (3711) of FIG. 15A).
[0099] In one embodiment, the coil (373) may be disposed between the diaphragm (371) and the yoke (377). For example, the coil (373) may contact, be adjacent to, and / or be connected to one side (e.g., the +Z direction side) of the diaphragm (371). The coil (373) may be disposed within a magnetic field formed by the magnetic member (376). For example, the coil (373) may receive an electric signal from a processor (e.g., the processor (120) of FIG. 1) to generate an electric field. For example, the coil (373) may be moved relative to the magnetic member (376) by the interaction of the magnetic field and the electric field. For example, the coil (373) may reciprocate linearly in a direction (Z axis direction) toward or away from the yoke (377) or the first speaker cover (362). For example, the coil (373) can cause a vibration plate (371) that is in contact with or connected to the coil (373) to reciprocate linearly while reciprocating linearly.
[0100] In one embodiment, the speaker (370) may further include a suspension (or edge or surrounder) (372). In one embodiment, the suspension (372) may connect the diaphragm (371) to the magnetic member (376) or the frame (375). In one embodiment, the suspension (372) may be disposed around the periphery of the diaphragm (371), for example, so as to surround at least a portion of an edge of the diaphragm (371). For example, the diaphragm (371) may be referred to as a high-frequency dome of the diaphragm, and the suspension (372) may be referred to as a low-frequency dome of the diaphragm. For example, the suspension (372) may be connected to or formed integrally with the diaphragm (371).
[0101] In one embodiment, the elastic force of the suspension (372) can support the diaphragm (371) that moves in a linear reciprocating motion. For example, when the speaker (370) is operated and the diaphragm (371) moves in a linear reciprocating motion, the suspension (372) can provide an elastic force that moves the diaphragm (371) to its initial position before the speaker (370) is operated. In one embodiment, the suspension (372) can move in a linear reciprocating motion together with the diaphragm (371) in a direction (Z-axis direction) toward or away from the yoke (377) or the first speaker cover (362). For example, the distance or range of the linear reciprocating motion of the suspension (372) can be smaller than the distance or range of the linear reciprocating motion of the diaphragm (371). For example, the suspension (372) may include a bent portion (e.g., the bent portion (3712) of FIG. 7B) that is bent or protrudes in a direction opposite to the position of the diaphragm (371) or toward the magnetic member (376) or the yoke (377). For example, the bent portion (3712) may be a structure that reinforces the elasticity of the suspension (372). For example, the suspension (372) may include metal or synthetic resin.
[0102] In one embodiment, the suspension (372) may be directly connected to the diaphragm (371), but the frame (375) may not be directly connected to the magnetic member (376) or the yoke (377). In one embodiment, the frame (375) is coupled to an edge of the suspension (372) and may be mounted to another structure, for example, either the yoke (377) or the magnetic member (376). For example, the frame (375) and / or the suspension (372) may support the diaphragm (371) so as to be able to move linearly and reciprocally.
[0103] In one embodiment, the magnetic member (376) may be a permanent magnet and may be disposed between the diaphragm (371) and the yoke (377). For example, the magnetic member (376) may provide a magnetic force that interacts with the electric force of the coil (373) to cause the coil (373) to move linearly back and forth. In one embodiment, the magnetic member (376) may include a first magnetic member (376a) surrounded by the coil (373) and a second magnetic member (376b) disposed around the outer periphery of the coil (373). For example, the second magnetic member (376b) may be disposed spaced apart from the first magnetic member (376a) and the coil (373) with the first magnetic member (376a) interposed therebetween. The shape, number, and / or arrangement of the magnetic members (376) may be changed according to the specifications required by the speaker assembly (305) to be actually manufactured and / or the electronic device (101) including the same.
[0104] In one embodiment, the plate (374) can be disposed between the diaphragm (371) and the first magnetic member (376a). In one embodiment, the plate (374) can be disposed on one side (e.g., the -Z direction side) of the first magnetic member (376a). In one embodiment, the frame (375) can be disposed between the diaphragm (371) and the second magnetic member (376b). In one embodiment, the frame (375) can be disposed on one side (e.g., the -Z direction side) of the second magnetic member (376b), and a portion of the frame (375) can be connected to the suspension (372). For example, the plate (374) and / or the frame (375) can align the direction or distribution of a magnetic field generated by the magnetic member (376).
[0105] In one embodiment, the yoke (377) can be positioned to face the diaphragm (371) and the suspension (372) with other components of the speaker (370) interposed therebetween (e.g., the coil (373), the plate (374), the frame (375), and / or the magnetic member (376). For example, the yoke (377) can support the linear reciprocating motion of the coil (373), the diaphragm (371), and / or the suspension (372). For example, the yoke (377) can align the direction or distribution of a magnetic field generated by the magnetic member (376). For example, the yoke (377) can act to focus the magnetic field generated by the magnetic member (376) onto the internal components of the speaker (370) (e.g., the coil (373)) in conjunction with the plate (374) and / or the frame (375).
[0106] Figures 8a and 8b are drawings for comparing and explaining the positions of the diaphragm (371) and suspension (372) before and during operation of the speaker assembly (305).
[0107] According to one embodiment, as described above, when the speaker assembly (305) operates, the diaphragm (371) can linearly reciprocate in a direction (Z-axis direction) toward or away from the yoke (377) or the first speaker cover (362) based on the electromagnetic force formed by the coil (373) and the magnetic member (376) and / or the elastic force of the suspension (372). According to one embodiment, the suspension (372) can linearly reciprocate in a direction (Z-axis direction) toward or away from the yoke (377) or the first speaker cover (362) together with the diaphragm (371). For example, the distance or range of the linear reciprocating movement of the suspension (372) may be smaller than the linear reciprocating movement distance or range of the linear reciprocating movement of the diaphragm (371).
[0108] Referring to FIG. 8A, before the speaker assembly (305) operates, the distance between the first speaker cover (362) and the diaphragm (371) may be a first distance (d1) (e.g., the first distance (d1) of FIGS. 6 to 7B), and the distance between the step structure (366) and the suspension (372) may be a second distance (d2) (e.g., the second distance (d2) of FIGS. 6 to 7B). For example, the first distance (d1) may be in a range of about 0.45 mm to about 0.65 mm, or in a range of about 0.5 mm to about 0.6 mm, and may be about 0.55 mm as an example.
[0109] FIG. 8B may represent, for example, a state in which the diaphragm (371) and the suspension (372) are arranged closest to the first speaker cover (362) or the step structure (366) when the speaker assembly (305) operates. Referring to FIG. 8B, the first-second distance (d12) may be the minimum value of the gap between the first speaker cover (362) and the diaphragm (371) when the speaker assembly (305) operates. According to one embodiment, the step structure (366) may be spaced apart from the diaphragm (371) and the suspension (372) so as to come into contact with the diaphragm (371) or the suspension (372) when the speaker (370) operates. For example, the second-second distance (d22) may be the minimum value of the gap between the step structure (366) and the suspension (372) when the speaker assembly (305) operates. In one embodiment, the second-second distance (d22) may be smaller than the first-second distance (d12). For example, the ratio of the first-second distance (d12) to the second-second distance (d22) may be about 3:2. For example, the first-second distance (d12) may fall within a range of about 0.05 mm to about 0.25 mm, or within a range of about 0.1 mm to about 0.2 mm, and may be about 0.15 mm as an example. For example, the second-second distance (d22) may fall within a range of about 0.01 mm to about 0.2 mm, or within a range of about 0.5 mm to about 0.15 mm, and may be about 0.1 mm as an example. The state of the speaker assembly (305) illustrated in FIG. 8b is exemplary, and the relative positions of the diaphragm (371) and suspension (372) with respect to the yoke (377) or speaker housing (360) may be changed.
[0110] FIG. 9 is a cross-sectional perspective view of a speaker assembly according to one embodiment of the present disclosure. FIG. 10 is a cross-sectional perspective view of a speaker assembly according to one embodiment of the present disclosure.
[0111] The speaker assembly (305) of FIGS. 9 and 10 may be referred to as the speaker assembly (305) of FIGS. 6, 7a, 8a, and 8b.
[0112] Referring to FIG. 9, in one embodiment, the first speaker cover (362) may include a first recess (3621) that is sunken toward the speaker (370) (e.g., the speaker (370) of FIGS. 6 and 7A) in a portion thereof. For example, the edge of the first recess (3621) may have a closed curve shape. For example, another configuration of an electronic device (e.g., the electronic device (101) of FIGS. 1 to 7A) may be disposed on an outer surface of the first recess (3621). For example, an electrical / electronic component or a conductive component may be disposed on the outer surface of the first recess (3621) by interposing an intermediate member having elasticity and / or adhesiveness.
[0113] Referring to FIG. 9, in one embodiment, the gap between the first speaker cover (362) and the speaker (370) may include a first distance (d1) (e.g., the first distance (d1) in FIGS. 6, 7A, and 10) which is a gap between an area around the first recess (3621) of the first speaker cover (362) and a diaphragm (e.g., the diaphragm (371) in FIGS. 6 to 11 and 10) of the speaker (370) and a first-1 distance (d12) which is a gap between the first recess (3621) and the diaphragm (371).
[0114] Referring to FIG. 10, the first speaker cover (362) may not include a sunken area such as the first recess (3621) of FIG. 9. Referring to FIG. 10, the diaphragm (371) may include a second recess (3711) (e.g., 3711 of FIG. 15A) in which a portion of the central portion is sunken toward the yoke (377). According to the embodiment of FIG. 10, the first distance (d1) (e.g., the first distance (d1) of FIGS. 6, 7A, and 10) between the first speaker cover (362) and the diaphragm (371) may be the distance between the first speaker cover (362) and an area around the second recess (3711) of the diaphragm (371).

FIG. 12 is a schematic cross-sectional side view of the speaker assembly of FIG. 11 according to an embodiment of the present disclosure. FIG. 13 is a schematic plan view illustrating a portion of a speaker assembly of an electronic device according to an embodiment of the present disclosure. FIG. 14 is a graph illustrating a change in sound pressure according to frequency due to a step structure of a speaker assembly according to an embodiment of the present disclosure.
[0116] The first speaker hole (317), the side frame (322), the first support structure (361), the first speaker cover (362), the step structure (366), the diaphragm (371), the suspension (372), the acoustic space (A1) and the passage (A2) illustrated in FIGS. 11, 12 and / or 13 may be referred to as the first speaker hole (317), the side frame (322), the first support structure (361), the first speaker cover (362), the step structure (366), the diaphragm (371), the suspension (372), the acoustic space (A1) and the passage (A2) of the embodiments of FIGS. 6 to 7b.
[0117] Referring to FIGS. 11 to 13, according to one embodiment, the step structure (366) may be in a form that protrudes from the surface of the first support structure (361) by a specified distance (L3) (e.g., L3 in FIG. 7b). According to one embodiment, when looking down at the first speaker cover (362) from above (or when looking in the +Z direction), the step structure (366) may not overlap with the diaphragm (371), but may overlap with at least a portion of the suspension (372).
[0118] Referring to FIGS. 11 to 13, in one embodiment, the step structure (366) can at least partially face an open area formed on one side of an acoustic space (A1) connected to a passage (A2). In one embodiment, the first portion (361a) of the first support structure (361) (e.g., the first portion (361a) of FIGS. 6 to 7B) can include a first sidewall (3611) that at least partially faces an open area formed on one side of an acoustic space (A1) connected to a passage (A2). According to one embodiment, the first support structure (361) can include a second sidewall (3612) extending from one end of the first sidewall (3611) and a third sidewall (3613) extending from the other end of the first sidewall (3611) and at least partially facing the second sidewall (3612). According to one embodiment, at least a portion of the single-pronged structure (366) may be positioned adjacent to an edge where the first side wall (3611) and the first speaker cover (362) meet.
[0119] Referring to FIG. 13, according to one embodiment, the step structure (366) may extend from a portion disposed on the first side wall (3611) to the second side wall (3612) and / or the third side wall (3613). Referring to FIG. 12, according to one embodiment, the step structure (366) may include a portion extending from a portion disposed on the first side wall (3611) to the second side wall (3612) and the third side wall (3613). According to one embodiment, the step structure (366) disposed on the second side wall (3612) may be in a form that protrudes from the second side wall (3612) toward the third side wall (3613) by a specified distance (L3). According to one embodiment, the step structure (366) disposed on the third side wall (3613) may be in a form that protrudes a designated distance (L3) from the third side wall (3613) toward the second side wall (3612). According to one embodiment, the step structure (366) disposed on the second side wall (3612) and / or the third side wall (3613) may overlap at least a portion of the suspension (372) without overlapping the diaphragm (371) when looking down at the first speaker cover (362) from above (or when looking in the +Z direction). The shape or arrangement of the step structure (366) illustrated in FIG. 13 may be changed. For example, the step structure (366) may include a portion that extends from a portion disposed on the first side wall (3611) to either the second side wall (3612) or the third side wall (3613). For example, the protrusion length of the step structure (366) may be at least partially shorter or longer than the specified length (L3).
[0120] Referring to FIG. 12, in one embodiment, sound (or sound wave or vibration) output from the speaker (370) may travel along a first path (S1) toward the first speaker hole (317), or may travel along a second path (S2) toward the first speaker hole (317) by being reflected on the surface of a side wall (e.g., the first side wall (3611)) of the first support structure (361). Here, the sound traveling along the first path (S1) and the sound traveling along the second path (S2) may destructively interfere with each other or constructively interfere with each other. When the sounds traveling along the first path (S1) and the second path (S2) destructively interfere with each other, a dip (e.g., the dip in FIG. 14) may occur in a specific frequency band. According to one embodiment of the present disclosure, the step structure (366) can adjust the frequency of sound that is reflected by the step structure (366) and travels along a second path (S2) toward the first speaker hole (317) and the frequency at which destructive interference occurs. According to one embodiment, the step structure (366) can shift a specific frequency band where a dip occurs to a higher frequency range compared to a specific frequency band where a dip occurs when the step structure (366) is not provided. By shifting the specific frequency band where a dip occurs to a higher frequency range, the high-frequency performance of the speaker assembly (305) can be improved.
[0121] Referring to FIGS. 11 to 13, the first length (L1) is a distance from the first side wall (3611) to the boundary between the acoustic space (A1) and the passage (A2), the second length (L2) is a distance from the first side wall (3611) to the center of the diaphragm (371), and the designated distance (L3) may be a distance from the end of the step structure (366) to the first side wall (3611) or a distance by which the step structure (366) protrudes from the first side wall (3611). Here, the first length (L1), the second length (L2), and the designated distance (L3) may be straight-line distances measured based on the Y-axis.
[0122] In Fig. 14, the horizontal axis (X-axis) may represent the frequency value (Hz) of the sound output from the speaker assembly (305), and the vertical axis (Y-axis) may represent the magnitude (dB) of the response at the frequency value. Graph A in Fig. 14 may represent the response characteristic for frequency of the speaker assembly (305) before adding the single-step structure (366) according to one embodiment of the present disclosure. Graph P in Fig. 14 may represent the response characteristic for frequency of the speaker assembly (305) to which the single-step structure (366) according to one embodiment of the present disclosure is added.
[0123] Referring to FIG. 14, a first resonant frequency at which a first peak occurs due to resonance of sound (or sound wave or vibration) in graph A and graph P and a second resonant frequency at which a second peak occurs are indicated. The following [Mathematical Expression 1] can represent the relationship between the wavelength of the resonant frequency and the length (L1) (the first length (L1) in FIGS. 11 to 13) from the first side wall (3611) to the boundary between the acoustic space (A1) and the passage (A2). For example, in [Mathematical Expression 1], 'λ peak ' can represent the wavelength of the first resonant frequency when n=1, and the wavelength of the second resonant frequency when n=2.
[0124] [Mathematical Formula 1]
[0125]
[0126] (Here, λ represents wavelength, f represents frequency, and c represents the speed of sound in the medium.)
[0127] The above [Mathematical Formula 1] is merely an example to aid understanding and is not limited thereto, and can be modified, applied, or expanded in various ways.
[0128] Referring again to FIG. 11, according to one embodiment, the fourth length (L1') may be the distance from the center of the suspension (372) to the boundary between the acoustic space (A1) and the passage (A2). The fourth length (L1') may be a value obtained by reducing the first length (L1), which is the distance from the first side wall (3611) to the boundary between the acoustic space (A1) and the passage (A2), by a designated distance (L3), which is the distance to the first side wall (3611), by adding a step structure (366) to the first support structure (361). According to one embodiment, the fifth length (L2') may be the distance from the center of the suspension (372) to the center of the diaphragm (371). The fifth length (L2') may be a value obtained by reducing the second length (L2), which is the distance from the first side wall (3611) to the center of the vibration plate (371), by a designated distance (L3), which is the distance to the first side wall (3611), by adding a step structure (366) to the first support structure (361). Here, the fourth length (L1') and the fifth length (L2') may be straight-line distances measured based on the Y-axis.
[0129] Referring to FIGS. 12 and 14 , a dip may occur in a specific frequency band due to destructive interference of sound (or vibration or sound) traveling along the first path (S1) of FIG. 12 and the second path (S2) of FIG. 12 . Referring to FIG. 14 , according to one embodiment, by adding a step structure (366) to the first support structure (361), the frequency at which the dip occurs may be shifted to a higher frequency range. Referring to FIG. 11, according to one embodiment, by adding a step structure (366) to the first support structure (361), a first length (L1), which is a distance from the first side wall (3611) to the boundary between the acoustic space (A1) and the passage (A2), may be reduced to a fourth length (L1'), and a second length (L2), which is a distance from the first side wall (3611) to the center of the diaphragm (371), may be reduced to a fifth length (L2'). The fifth length (L2') of FIG. 11 may be a value that affects a specific frequency band in which a dip occurs. According to one embodiment, the step structure (366) may change the frequency of a sound that is reflected and propagates from the step structure (366) (e.g., a sound that propagates along the second path (S2) of FIG. 12) and thus a specific frequency band in which a dip occurs, by reducing the second length (L2) by a designated distance (L3). [Mathematical expression 2] below can represent the relationship between the wavelength at which a dip occurs and the fifth length (L2'). From [Mathematical expression 2], when the fifth length (L2') is reduced due to the addition of the step structure (366), the frequency (f) at which a dip occurs dip ) can be seen to increase, i.e. move to the high band.
[0130] [Equation 2]
[0131]
[0132] (Here, λ represents wavelength, f represents frequency, and c represents the speed of sound in the medium.)
[0133] The above [Mathematical Formula 2] is merely an example to aid understanding and is not limited thereto, and can be modified, applied, or expanded in various ways.
[0134] Referring to the above-described [Mathematical Formula 2] and the graph of FIG. 14, it can be confirmed that a specific frequency band in which a dip occurs in the speaker assembly (305) to which the step structure (366) is added moves to a higher frequency range compared to graph A before adding the step structure (366) according to one embodiment of the present disclosure. Accordingly, the high-frequency performance or sound quality of the speaker assembly (305) can be improved.
[0135] FIG. 15A is a cross-sectional side view of an electronic device for illustrating a speaker assembly according to one embodiment of the present disclosure. FIG. 15B is an enlarged view of portion C of FIG. 15A according to one embodiment of the present disclosure.
[0136] The speaker assembly (305) of FIGS. 15A and 15B may be referred to as the speaker assembly (305) of FIGS. 6, 7A, 8A to 10. The description given above with reference to FIGS. 11 to 14 may be substantially equally applied to the embodiment of FIGS. 15A and 15B. Hereinafter, the step structure (366) of the embodiment of FIGS. 15A and 15B may be described focusing on the different features from the step structure (366) of the embodiment of FIGS. 6 to 10, and any content overlapping with the description given above with reference to FIGS. 6 to 10 may be omitted.
[0137] Referring to FIGS. 15A and 15B , in one embodiment, the step structure (366) may include a different material from the first support structure (361). For example, the first support structure (361) may include various materials such as synthetic resin or rubber. For example, the step structure (366) may include various materials such as metal (e.g., stainless steel), synthetic resin, or rubber. In one embodiment, the step structure (366) may be manufactured separately from the first support structure (361) and connected to the first support structure (361). In one embodiment, the step structure (366) may be formed integrally with the first support structure (361). For example, the first support structure (361) may be formed integrally with the step structure (366) through various processes such as double injection molding or a cutting process.
[0138] Referring to FIG. 15B, according to one embodiment, the step structure (366) may be connected to the first support structure (361) and / or the first speaker cover (362). For example, the step structure (366) may be arranged at a distance (t1) from the first support structure (361). For example, the distance (t1) between the step structure (366) and the first support structure (361) may be a distance required in the manufacturing process and may be omitted as needed. According to one embodiment, the step structure (366) may be arranged to contact the first support structure (361) without a distance (t1), in which case the step structure (366) may be in a form that protrudes from a portion of the first support structure (361) by a specified distance (L3).
[0139] Typically, a speaker device may have a forward wave, which is output from the diaphragm and travels directly toward the speaker hole, and a reflected wave, which is output from the diaphragm and reflects off the side wall opposite the speaker hole and travels toward the speaker hole. The forward wave and the reflected wave may interfere with each other, resulting in a dip in a specific frequency band. This dip can degrade the high-frequency performance of the speaker device.
[0140] Aspects of the present disclosure are intended to solve at least the problems and / or disadvantages described above and to provide at least the advantages described below.
[0141] According to one embodiment of the present disclosure, by adding a step structure to a side wall disposed opposite a speaker hole in a speaker assembly, the frequency of a reflected wave reflected from the side wall is changed, thereby moving the frequency band where a dip occurs to a high band, thereby improving the high-frequency performance of the speaker assembly.
[0142] However, the challenges addressed by this disclosure are not limited to the aforementioned challenges, and may be determined in various ways without departing from the spirit and scope of this disclosure. The benefits achieved by this disclosure are not limited to the aforementioned benefits, and various benefits may be provided, directly or indirectly, through this document.
[0143] According to one embodiment of the present disclosure, an electronic device (101) may be provided. The electronic device may include a housing (210) including a first speaker hole (217; 317), a speaker assembly (305) disposed within the housing and configured to radiate sound to the outside of the electronic device through the first speaker hole. The speaker assembly may include a speaker (370) including a diaphragm (371), a first speaker cover (362) facing the diaphragm and spaced apart from the diaphragm, an acoustic space (A1) formed between the diaphragm and the first speaker cover, a first support structure (361) including a first portion (361a) formed to surround a portion of the acoustic space, and a step structure (366) disposed adjacent to an area where a portion of the first portion of the first support structure and the first speaker cover come into contact and spaced apart from the speaker.
[0144] According to one embodiment, the step structure may be arranged so as not to overlap the diaphragm when viewed from above the speaker cover.
[0145] According to one embodiment, the first support structure may further include a second portion (361b) extending from the first portion and including a passage (A2) connecting the acoustic space and the first speaker hole. The first portion of the first support structure may include a first side wall (3611) at least partially facing the passage. At least a portion of the step structure may be disposed adjacent to an area where the first side wall and the first speaker cover contact each other.
[0146] According to one embodiment, the step structure may be formed to protrude a specified distance (L3) from a portion of the first side wall toward the passage.
