Description

Speaker module and electronic device including same

[0001] Embodiments of the present disclosure relate to a speaker module and an electronic device including the same.

[0002] As electronic devices become more sophisticated, they are increasingly equipped with electronic components that perform a variety of functions. One example of such components is a speaker module for sound output. A speaker module utilizes a surround sound chamber embedded in a diaphragm to facilitate air vibration, converting electrical signals generated by the electronic device into audible sound signals that can be heard by the user.

[0003] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above-described matters constitute prior art related to the present disclosure.

[0004] Meanwhile, as electronic devices become thinner, the thickness of speaker modules may also be required to be thinner. In this case, the magnetic circuitry constituting the speaker may become thinner, which may result in a loss of magnetic strength relative to the speaker module's magnetic field, thereby degrading the speaker module's output characteristics (e.g., sound pressure).

[0005] A speaker module according to various embodiments of the present disclosure may include a first magnet for securing magnetic force and a second magnet substantially surrounding the first magnet and positioned spaced apart from the first magnet. The speaker module may include a conductive wire (e.g., a flexible circuit board and / or a rigid circuit board) for connecting a coil included in the speaker module and an external electrode. The conductive wire included in the speaker module may form an electrical path connecting the coil and the external electrode through a space between the surround of the diaphragm and the frame, in an external space of the second magnet.

[0006] An electronic device according to one embodiment of the present disclosure may include a housing and a speaker module accommodated in the housing. The speaker module according to one embodiment may include a yoke forming one side of the speaker module, a diaphragm forming the other side of the speaker module, a frame forming a side surface of the speaker module, a first magnet disposed between the yoke and the diaphragm, a second magnet substantially surrounding the first magnet and disposed spaced apart from the first magnet, a coil attached to a region of the diaphragm substantially corresponding to a space between the first magnet and the second magnet, and a conductive wire for providing power to the coil. The conductive wire of the speaker module according to one embodiment may include a first wiring portion extending from the coil toward the frame, a second wiring portion extending from the first wiring portion toward the yoke, and a third wiring portion extending from the second wiring portion toward the frame.

[0007] A speaker module according to one embodiment of the present disclosure may include a yoke forming one side of the speaker module, a diaphragm forming the other side of the speaker module, a frame forming a side surface of the speaker module, a first magnet disposed between the yoke and the diaphragm, a second magnet substantially surrounding the first magnet and disposed spaced apart from the first magnet, a coil attached to a region of the diaphragm substantially corresponding to a space between the first magnet and the second magnet, and a conductive wire for providing power to the coil. The conductive wire of the speaker module according to one embodiment may include a first wiring portion extending from the coil toward the frame, a second wiring portion extending from the first wiring portion toward the yoke, and a third wiring portion extending from the second wiring portion toward the frame.

[0008] The speaker module and the electronic device including the same according to various embodiments of the present disclosure include a first magnet and a second magnet substantially surrounding the first magnet and spaced apart from the first magnet, thereby increasing magnetic field efficiency and reducing deterioration of output characteristics (e.g., sound pressure) of the speaker module.

[0009] The speaker module and electronic device including the same according to various embodiments of the present disclosure can contribute to slimming down the speaker module by forming an electrical path connecting the coil and the external electrode through the space between the surround and the frame of the diaphragm to the external space of the second magnet using conductive wiring (e.g., a flexible circuit board and / or a rigid circuit board).

For example, at least another portion (e.g., the 3-2 wiring portion (43032)) of the second wiring portion (4302) and the third wiring portion (4303) may be a region that is not coupled (or fixed) to at least a portion of the diaphragm (420), and thus may be formed of a flexible material. Forming the region that is not coupled (or fixed) to at least a portion of the diaphragm (420), which is the second wiring portion (4302) and the third wiring portion (4303) of the conductive wiring (430), of a flexible material may be advantageous in the design and manufacturing processes.

[0122] In one embodiment, a peripheral area (e.g., surround (410)) of the diaphragm (420) may include a protruding area (615) protruding toward the yoke (490). At least a portion of the second wiring portion (4302) of the conductive wiring (430) may be positioned opposite the frame (460) with respect to the protruding area (615). In one embodiment, at least a portion of the third wiring portion (4303) of the conductive wiring (430) may be formed below the protruding area (615).

[0123] In the aforementioned FIGS. 6A and 6B according to various embodiments, the second wiring portion (4302) of the conductive wiring (430) is described as extending from the first wiring portion (4301) toward the yoke (490), and the third wiring portion (4303) of the conductive wiring (430) is described as extending from the second wiring portion (4302) toward the frame (460), but is not limited thereto.

[0124] Specifically, in one embodiment, the first wiring portion (4301) may extend from the coil (440) toward the frame (460). In one embodiment, the second wiring portion (4302) may extend from an end (4301a) of the first wiring portion (4301) that is distant from (or spaced apart from) the coil (440) toward the yoke (490). In one embodiment, the third wiring portion (4303) may extend from an end (4302a) of the second wiring portion (4302) that is distant from (or spaced apart from) the first wiring portion (4301) toward the frame (460).

[0125] For example, referring to FIGS. 6b and 6c, the second wiring portion (4302) of the conductive wiring (430) may include an extension portion (43021) that extends in a direction substantially parallel to one side of the second magnet (470) that the second wiring portion (4302) faces (e.g., in the y-axis direction) and includes a portion formed lower than the lowest point height of the protruding area (615) of the surround (410). In this case, the third wiring portion (4303) may also extend from the extension portion (43021) toward the frame (460) (e.g., in the x-axis direction).

[0126] According to one embodiment, the coil (440) and the external electrode can be electrically connected using conductive wiring (430) (e.g., the first wiring portion (4301), the second wiring portion (4302), and the third wiring portion (4303)) without interfering with the movement of the diaphragm (420) through the space between the protruding area of ​​the surround (410) of the diaphragm (420), which is the external space of the second magnet (470), and the frame (460). Accordingly, it can contribute to the slimming of the speaker module (400). In addition, by including the first magnet (465) and the second magnet (470) arranged in a form that substantially surrounds the first magnet (465), the magnetic field efficiency can be increased, so that the acoustic performance of the speaker module (400) can be improved.

[0127] FIG. 7 is a drawing for explaining the effective area of ​​a vibration plate (420) of a speaker module (400) according to one embodiment of the present disclosure.

[0128] As described in various embodiments, as shown in FIGS. 4, 5, and 6A, a conductive wire (e.g., a conductive wire (430) of FIG. 4) can electrically connect a coil (e.g., a coil (440) of FIG. 4)) and an external electrode (e.g., an electrode disposed outside the speaker module (400). For example, the conductive wire (430) can connect the coil (440) and the external electrode through a space between a protruding area of ​​a surround (e.g., a surround (410) of FIG. 4) formed to protrude in a second direction (e.g., a -z-axis direction) along an edge of a diaphragm (e.g., a diaphragm (420) of FIG. 4), which is an external space of a second magnet (e.g., a second magnet (470) of FIG. 4), and a frame (e.g., a frame (460) of FIG. 4). However, the present invention is not limited thereto.

In one embodiment, at least another portion of the conductive wiring (430) (e.g., the second wiring portion (4302), the third wiring portion (4303)) may be bent in a second direction (e.g., the -z-axis direction) and a third direction (e.g., the x-axis direction) by a specified length from one end of the at least a portion of the effective area (710) of the diaphragm (420) to be electrically connected to an external electrode.

[0130] FIG. 8 is a drawing for explaining a first conductive plate portion (445) and / or a second conductive plate portion (450) of a speaker module (400) according to one embodiment of the present disclosure.

For example, in FIG. 8 <810> As illustrated, the first conductive plate portion (445) may include a first step (815) formed along the outer peripheral surface of the first conductive plate portion (445) (e.g., formed in the outer edge region). For another example, FIG. 8 <850> As illustrated, the second conductive plate portion (450) may include a second step (855) formed along an inner peripheral surface of the second conductive plate portion (450) (e.g., formed in an inner edge region).

[0134] In one embodiment, the first conductive plate portion (445) includes a first step (815), and / or the second conductive plate portion (450) includes a second step (855), thereby contributing to an increase in the efficiency of the magnetic field of the magnetic field lines or magnetic circuit (e.g., the first conductive plate portion (445), the second conductive plate portion (450), the first magnet (465), the second magnet (470), and the yoke (490)) generated by interaction with the coil (440) to reduce the deterioration of the output characteristics (e.g., sound pressure) of the speaker module (400).

[0135] In FIG. 8 according to various embodiments, the first conductive plate portion (445) and / or the second conductive plate portion (450) are described as including steps (e.g., the first step (815) and / or the second step (855)), but are not limited thereto. For example, the first magnet (e.g., the first magnet (465) of FIG. 4) and / or the second magnet (e.g., the second magnet (470) of FIG. 4) of the speaker module (400) may include steps to increase magnetic field efficiency (or magnetic field density). In this regard, various embodiments will be described in FIG. 9 described below.

[0136] FIG. 9 is a drawing for explaining the first magnet (465) and / or the second magnet (470) of the speaker module (400) according to one embodiment of the present disclosure.

[0137] Referring to FIG. 9, the first magnet (465) may be arranged in a central region of the speaker module (400) when viewed from the rear side (e.g., the side facing the -z axis) of the speaker module (e.g., the speaker module (400) of FIG. 4). The second magnet (470) may substantially surround the first magnet (465) and may be arranged to be spaced apart from the first magnet (465). For example, the second magnet (470) may have a closed-loop structure or annular structure. For example, the second magnet (470) may have a closed-loop structure or annular structure and may have a circular, square, oval, or track-shaped shape.

[0138] In one embodiment, when viewed from the rear (e.g., the side facing the -z-axis) of the speaker module (400), the coil (e.g., the coil (440) of FIG. 4) may be at least partially disposed in the space (440a) between the first magnet (465) and the second magnet (470).

[0139] In one embodiment, the first magnet (465) and the second magnet (470) may be mounted on a yoke (e.g., the yoke (490) of FIG. 4). The first magnet (465) and the second magnet (470) may form a magnetic field to cause the coil (440) to vibrate up and down.

[0140] In one embodiment, the first magnet (465) and / or the second magnet (470) may include steps to increase magnetic field efficiency (or magnetic field density).

[0141] For example, in Fig. 9 <910> As illustrated, the first magnet (465) may include a protruding region (4655) formed in the central region of the first magnet (465). In this case, the first conductive plate portion (445) positioned to correspond to the first magnet (465) may include an opening (4455) formed to correspond to the protruding region (4655) formed in the central region of the first magnet (465).

[0142] For example, in Fig. 9 <950> As illustrated, the second magnet (470) may include a step (4705) formed along the outer peripheral surface of the second magnet (470). In this case, the second conductive plate portion (450) arranged to correspond to the second magnet (470) may be formed to be arranged on one side of the second magnet (470) (e.g., one side having a height lower than the height of the step (4705) formed along the outer peripheral surface of the second magnet (470)).

[0143] In one embodiment, the first magnet (465) includes a protruding area (4655), and / or the second magnet (470) includes a step (4705), thereby contributing to an increase in the efficiency of the magnetic field of the magnetic field lines or magnetic circuit (e.g., the first conductive plate portion (445), the second conductive plate portion (450), the first magnet (465), the second magnet (470), and the yoke (490)) generated by interaction with the coil (440) to reduce the deterioration of the output characteristics (e.g., sound pressure) of the speaker module (400).

[0144] FIG. 10 is a cross-sectional view schematically showing the configuration of a speaker module (400) according to one embodiment of the present disclosure.

[0145] Referring to Fig. 10, Fig. 10 <1010> and <1050> is a drawing of a speaker module (e.g., speaker module (400) of FIG. 4) viewed from the side (e.g., the side facing the y-axis).

[0146] In one embodiment, the speaker module (400) may include a frame (460), a diaphragm (420), a conductive wire (430), a coil (440), a first conductive plate portion (445), a second conductive plate portion (450), a first magnet (465), a second magnet (470), and / or a yoke (490). Although not shown, the speaker module (400) may further include a conductive wire (e.g., the conductive wire (430) of FIG. 4) and an air vent (not shown).

[0147] In one embodiment, the yoke (490) may form one side (e.g., a side facing the -z-axis) of the speaker module (400). In one embodiment, the yoke (490) may secure the first magnet (465) and the second magnet (470). For example, the yoke (490) may be formed of a material that conducts magnetic force well, such as a cobalt alloy (FeCo).

[0148] In one embodiment, the first magnet (465) may be positioned in the central region of the speaker module (400). The second magnet (470) may substantially surround the first magnet (465) and may be positioned spaced apart from the first magnet (465).

The second conductive plate portion (450) can be disposed at a position corresponding to the second magnet (470) in the first direction (e.g., toward the z-axis). The second conductive plate portion (450) can substantially surround the first conductive plate portion (445) and be disposed spaced apart from the first conductive plate portion (445). In one embodiment, the second conductive plate portion (450) can be formed of a material that conducts magnetic force well, for example, a cobalt alloy (FeCo).

[0150] In one embodiment, the coil (440) may be disposed on the inner surface of the diaphragm (420).

For example, the center cap (415) may be positioned at a position corresponding to the coil (440) in a first direction (e.g., toward the z-axis). The center cap (415) may contribute to determining the directionality of sound waves. The surround (410) may be formed adjacent to and along an edge of the diaphragm (420). In one embodiment, the surround (410) may include a protruding region (e.g., a protruding region (615) of FIG. 6A) formed to protrude in a second direction (e.g., in the -z-axis direction) along the edge of the diaphragm (420).

[0152] In one embodiment, although not shown, the conductive wiring (430) may electrically connect the coil (440) and an external electrode (e.g., an electrode disposed outside the speaker module (400). For example, the conductive wiring (430) may electrically connect the coil (440) and the external electrode through a space between the protruding area (615) of the surround (410) of the diaphragm (420), which is an external space of the second magnet (470), and the frame (460).

[0153] In one embodiment, the first conductive plate portion (445), the second conductive plate portion (450), the first magnet (465), the second magnet (470), and the yoke (490) of the speaker module (400) may constitute a magnetic circuit of the speaker module (400). For example, the first conductive plate portion (445), the second conductive plate portion (450), the first magnet (465), the second magnet (470), and the yoke (490) may constitute a magnetic circuit of the speaker module (400) and serve to maximize the magnetic field density at a location where the coil (440) is disposed.

In this case, the inside of the speaker module (400) may not be ventilated to the outside by the yoke (490). For another example, in FIG. 10 <1050> As shown in , among the components constituting the magnetic circuit of the speaker module (400), only a part (1055) of the first conductive plate portion (445) may be removed. In this case, the interior of the speaker module (400) may not be ventilated to the outside by the first magnet (465) and the yoke (490).
