Referring to FIGS. 5A to 5C, the speaker module 300 includes a plate 310, a speaker (e.g., the speaker 320 in FIG. 5c), a case 330, and/or a sealing member (e.g., the speaker in FIG. 5c). It may include a sealing member 340). FIG. 5B is a diagram in which the printed circuit board 250 is omitted.

According to one embodiment, the plate 310 may include a first part 311, a second part 312, and a third part 313. Referring to FIG. 5C, the first portion 311 may be in contact with one side (eg, one side 251 of FIG. 5C) of a printed circuit board (eg, printed circuit board 250 of FIG. 5C). For example, the first portion 311 may contact one surface 251 of the printed circuit board 250 facing the -z direction. The second part 312 is oriented in a direction (e.g., the other side 252 in FIG. 5C) opposite to the one side 251 of the printed circuit board 250 with respect to the first part 311. Example: +z direction) may be spaced apart. For example, the first part 311 and the second part 312 may be disposed at different points with respect to the z-axis direction. The second portion 312 may extend toward a speaker hole (eg, speaker hole 207 in FIG. 4A). The third part 313 may be disposed between the first part 311 and the second part 312. The second part 312 may extend from the first part 311 in a direction toward which the other surface 252 faces (eg, +z direction). The plate 310 is molded so that a portion of the plate protrudes from a plane, so that it can be distinguished into a first part 311, a second part 312, and a third part 313. For example, the plate 310 includes a first part 311 formed of a plane, a second part 312 formed of a plane spaced apart from the first part, and the first part 311 and the second part. It may include a third part 313 disposed between 312. For example, the third part 313 may protrude from the first part 311. In order to smoothly connect the first part 311 and the second part 312, the third part 313 may have an inclination with respect to the first part 311.

Referring to FIG. 5C, the speaker 320 may be configured to output an audio signal. For example, the speaker 320 may include a diaphragm 321, at least one voice coil that provides vibration to the diaphragm 321, and a magnet capable of forming a magnetic field. When a current containing audio information flows through the voice coil, the diaphragm 321 may vibrate. The speaker 320 may be configured to output an audio signal based on the vibration of the diaphragm 321.

According to one embodiment, the case 330 may surround at least a portion of the speaker 320 to support the speaker 320. For example, the case 330 may include a support portion 331a that supports at least a portion of the surface of the speaker 320 facing the -z direction and at least a portion of the side surface of the speaker 320. The speaker 320 may be inserted into the support portion 331a. However, it is not limited to this.

According to one embodiment, the case 330 may be connected to the first portion 311 to form a first space S1. The first space S1 may be a space between the plate 310 and a surface of the speaker 320 facing the +z direction. The audio signal output from the speaker 320 may be output to the first space S1. For example, an audio signal may be output as the air in the first space S1 vibrates by the diaphragm 321.

According to one embodiment, the case 330 may be connected to the second portion 312 to form a second space S2. The second space S2 may be a duct that guides the output audio signal from the first space S1 to the speaker hole (eg, the speaker hole 207 in FIG. 4A). The second space S2 may be connected to the first space S1. The audio signal output from the speaker 320 may be transmitted to the audio hall through the first space (S1) and the second space (S2).

According to one embodiment, the case 330 may include a first body 331 and a second body 332. The first body 331 may include a support portion 331a that supports the speaker 320. The first body 331 may be connected to the first portion 311 to define a first space S1. For example, the first space S1 may be defined by the first part 311, the first body 331, and the speaker 320, but is not limited thereto. The second body 332 may include a through hole 333 connecting the second space S2 and the speaker hole (eg, the speaker hole 207 in FIG. 4A). The audio signal may be transmitted to the audio hole through the through hole 333. The second body 332 may be connected to the second portion 312 to define a second space S2. For example, the second space S2 may be defined by the second portion 312 and the second body 332, but is not limited thereto.

According to one embodiment, the second space S2 may be formed at a different location from the first space S1 in the z-axis direction. For example, the second part 312 may be stepped with respect to the first part 311 . The second body 332 may be stepped with respect to the first body 331 . For example, the second body 332 may be spaced apart from the first body 331 in the +z direction. As the electronic device 101 becomes smaller, the internal space of the housing 230 may be limited. The speaker module 300 can efficiently use the space inside the housing 230 through the stepped structure. For example, referring to FIG. 5C, because of the structure in which the speaker module 300 is stacked with at least a portion of the printed circuit board 250, the speaker module 300 and the speaker hole (e.g., the speaker hole 207 in FIG. 4A) ) may not be placed on the same plane. As the second body 332 is stepped with respect to the first body 331, the through hole 333 connected to the second space S2 can be disposed on the same plane as the speaker hole 207.

According to one embodiment, the area of the second space S2, which is the path through which the audio signal is transmitted to the speaker hall 207, may affect the quality of the audio signal. For example, if the area of a portion of the second space S2 is narrow, the quality of a high-pitched audio signal having a relatively high frequency may be deteriorated. Because high-pitched audio signals have high frequencies, they can have short wavelengths. High-pitched audio signals with short wavelengths may have weak diffraction. If the area of some areas of the second space (S2) is narrow, high-pitched audio signals may not pass through the second space (S2), so in a relatively high frequency band, the sound pressure level (sound) of the speaker module 300 pressure level (SPL) may decrease.

According to one embodiment, the plate 310 and the case 330 may form an enclosure surrounding the speaker 320. Since the first portion 311 of the plate 310 can be in contact with one side 251 of the printed circuit board 250, the gap between the plate 310 and the printed circuit board 250 can be eliminated. . For example, the first portion 311 may be soldered to the one surface 251 of the printed circuit board 250. Because the first portion 311 is in contact with one side 251 of the printed circuit board 250, the distance between the plate 310 and the case 330 can be increased. For example, by the first part 311 contacting one side 251 of the printed circuit board 250, the distance d1 between the third part 313 and the second body 332 can be increased. there is.

According to one embodiment, the minimum distance between the plate 310 and the case 330 may be referred to as the minimum distance d1 between the second body 332 and the third portion 313. According to one embodiment, the second part 312 may be stepped with respect to the first part 311, and the second body 332 may be stepped with respect to the first body 331. The second space S2 may be narrowed in a portion corresponding to the step structure. The area of the portion corresponding to the step structure may have the minimum area among the second space S2.

According to one embodiment, as the first portion 311 contacts one surface 251 of the printed circuit board 250, the gap between the plate 310 and the printed circuit board 250 may be eliminated. As the gap is removed, the distance d1 between the third portion 313 and the second body 332 can be increased. Since the distance d1 can be increased, the area of the portion corresponding to the step structure in the second space S2 can be increased.

According to one embodiment, in order to increase the distance d1, the third part 313 is located at a corner of the end 253 closest to the second part 312 among both ends of the printed circuit board 250. You can access it. For example, the distance d1 between the second body 332 and the third part 313 when the third part 313 is in contact with the corner of the end 253 of the printed circuit board 250. ), the second body 332 and the third part ( 313) It may be longer than the distance (d1) between them. According to one embodiment, as the distance d1 increases, the minimum area of the second space S2 may increase, and thus the quality of the audio signal may be improved.

Referring to FIGS. 5A and 5C , the first portion 311 may include an opening 314 . The opening 314 may expose a portion 251a of one surface 251 of the printed circuit board 250 to the first space S1. In FIG. 5A, the first portion 311 is shown as including one opening 314, but the number of openings 314 is not limited. For example, the first portion 311 may include two or more openings 314 spaced apart from each other.

According to one embodiment, a portion 251a of the printed circuit board 250 may be exposed to the first space S1 through the opening 314. A portion 251a of the printed circuit board 250 is located in the opening 314 among a portion of the printed circuit board 250 occupied by the speaker module 300 (e.g., portion P in FIG. 4B). It may be a corresponding area. The electronic device 101 according to one embodiment may further include at least one electronic component 350 connected to a portion 251a of the printed circuit board 250 exposed through the opening 314. At least one electronic component 350 may be at least one of components that are distinct from the speaker module 300. According to one embodiment, at least one electronic component 350 may be disposed on a portion 251a of the printed circuit board 250.

According to one embodiment, at least one electronic component 350 may occupy a portion of the first space S1. At least one electronic component 350 may be connected to a portion 251a of the printed circuit board 250 and disposed in the first space S1 between the speaker 320 and the first portion 311. According to one embodiment, at least one electronic component that is distinct from the speaker module 300 is installed in a partial area (e.g., partial area P in FIG. 4B) of the printed circuit board 250 occupied by the speaker module 300. Since 350 can be arranged, space within the housing 230 can be secured.

According to one embodiment, the at least one electronic component 350 that is distinct from the speaker module 300 is a portion 251a of the printed circuit board 250 exposed through the opening 314 of the first portion 311. It can be connected to the printed circuit board 250 through . According to one embodiment, at least one electronic component 350 may be connected to a partial region (e.g., partial region P in FIG. 4B) of the printed circuit board 250 occupied by the speaker module 300, The printed circuit board 250 may be electrically connected to more electronic components. Since the thickness of the plate 310 (e.g., about 0.2 mm) may be relatively thin, the speaker module 300 may be occupied by at least one electronic component 350 between the plate 310 and the speaker 320. You can secure space.

According to one embodiment, the speaker 320 may include a diaphragm 321. The diaphragm 321 can vibrate using a magnet and a voice coil. The diaphragm 321 can generate an audio signal through vibration.

It can be configured. When the diaphragm 321 vibrates, the position of the diaphragm 321 may change within the first space S1. For example, the position of the vibration plate 321 may change from the first position (P1), which is the position before vibration, to the second position (P2). The second position P2 may be the maximum movement position of the diaphragm 321 in the first direction. When the diaphragm 321 and at least one electronic component 350 come into contact, noise may be generated due to the contact. Within the first space S1, the space occupied by at least one electronic component 350 may be limited based on the position of the diaphragm 321.

Figure 7 is a graph showing changes in the sound pressure level of an audio signal output from an electronic device. The horizontal axis of the graph in FIG. 7 is the frequency (unit: Hz), and the vertical axis of the graph is the sound pressure level (SPL, unit) transmitted to the outside of the housing (e.g., the housing 230 in FIG. 4A). : dB).

The first graph 710 of FIG. 7 shows the sound pressure level of an audio signal output from an electronic device including a speaker module that does not include a plate. For example, a speaker module may include an injection molded enclosure, and the enclosure may be placed on a printed circuit board. The second graph 720 of FIG. 7 shows the sound pressure level of an audio signal output from an electronic device (eg, the electronic device 101 of FIG. 4A) according to an embodiment. The electronic device 101 according to one embodiment is a speaker module (e.g., a speaker module) including a plate (e.g., plate 310 in FIG. 5c) in contact with a printed circuit board (e.g., printed circuit board 250 in FIG. 5c). It may include the speaker module 300 of FIG. 5C).

A speaker (eg, speaker 320 in FIG. 5C) can output an audio signal through vibration within a limited space. An audio signal may form a standing wave or progressive wave in which an incident wave and a reflected wave are synthesized together. A portion of the audio signal output from the speaker 320 may overlap with reflected waves reflected by structures in the space, thereby reinforcing or canceling each other out. For example, a standing wave may have a peak or dip at a specific frequency. The frequency of the dip point of a standing wave may be referred to as the dip frequency.

Referring to FIG. 7, the first graph 710 and the second graph 720 may not show a significant difference in relatively low-pitched audio signals. At a frequency of about 2,000 Hz or higher, the second graph 720 may have a higher SPL than the first graph 710. At frequencies above about 5,000 Hz, the first graph 710 may have a low SPL. Because high-frequency audio signals have weak diffraction, they may not pass well through narrow ducts. The SPL of the first graph 710 may have a low SPL at a relatively high frequency. The second graph 720 may have a relatively high SPL at high frequencies. Referring to FIG. 7, it can be seen that in the frequency range of about 6,000 Hz to about 12,000 Hz, the SPL of the second graph 720 is up to about 7 dB higher than the SPL of the first graph 710. In the electronic device 101 according to one embodiment, since the plate 310 is in contact with the printed circuit board 250, the space between the plate 310 and the case 330 may be expanded. According to one embodiment, the area of the space (e.g., the second space (e.g., the second space S2 in FIG. 5c)) through which the audio signal is transmitted to the speaker hole (e.g., the speaker hole 207 in FIG. 4A) is expanded. According to one embodiment, by expanding the area, the SPL of the high-pitched audio signal can be improved.

The first graph 710 may have a dip frequency of approximately 12,500 Hz. The second graph 720 may have a dip frequency of approximately 13,500 Hz. The dip frequency of the standing wave can be determined based on the area of space. According to one embodiment, as the area of the space through which the audio signal is transmitted is secured, the dip frequency can be increased by about 1,000 Hz or more. According to one embodiment, the speaker module 300 may have a relatively high deep frequency, so the range of audio signals that can be provided can be expanded to a mainly used frequency range. For example, when the speaker 320 substantially outputs a high-pitched audio signal of about 12,000 Hz, the speaker module 300 with a deep frequency of 13,500 Hz can provide an audio signal of up to about 12,000 Hz. .
