Description

Technical Field

[0001] This disclosure relates to a speaker assembly and a display device including the speaker assembly. Background Technology

[0002] With the development of the information society, the requirements for display devices have increased in various forms. Correspondingly, in recent years, various display devices such as liquid crystal display devices (LCD), plasma display panels (PDP), electroluminescent displays (ELD), vacuum fluorescent displays (VFD), and organic light-emitting diodes (OLED) have been developed and put into use.

[0003] LCD panels can have a TFT substrate and a color substrate separated by a liquid crystal layer facing each other, and can display images using light provided from a backlight unit. OLED panels, on the other hand, can display images by depositing a self-emissive organic layer on a substrate with transparent electrodes.

[0004] Display devices can have speakers. A speaker is a device that converts electrical signals into sound waves to output sound. Speakers can be further classified according to their frequency range, such as woofers, midrange speakers, tweeters, and full-range speakers.

[0005] In recent years, with the trend towards thinner display devices, the thickness of the speakers installed in display devices is also decreasing. As speakers become thinner, the need to maintain a predetermined sound pressure level or to improve speaker performance by increasing the sound pressure level is also emerging.

The backlight unit 20 may be driven in a global driving mode or in a local driving mode such as local dimming or impulsive dimming. The backlight unit 20 may include an optical sheet 40 and an optical layer 30.

[0050] The optical sheet 40 can uniformly transmit light from the light source to the display panel 10. The optical sheet 40 can be composed of multiple layers. For example, the optical sheet 40 may include a prism sheet or a diffuser sheet, etc.

[0051] The frame 60 may be located behind the display panel 10, and the display panel 10 may be attached to the frame 60. The side frame 13 may be located between the display panel 10 and the frame 60, and may be attached to both the display panel 10 and the frame 60.

[0052] The back cover 70 may cover the rear of the frame 60. The back cover 70 may be attached to the frame 60. For example, the back cover 70 may be an injection-molded material of resin. As another example, the back cover 70 may include a metal material.

[0053] Reference Figure 3 and Figure 4 The backlight unit 20 may include an optical layer 30 and an optical sheet 40. The optical layer 30 may include a substrate 32, at least one light source 34, a reflector 36, and a diffuser 39.

[0054] The substrate 32 can be attached to the front side of the frame 60. The substrate 32 can be plate-shaped or composed of a plurality of straps spaced apart from each other in the vertical direction. The substrate 32 can be made of at least one of polyethylene terephthalate (PET), glass, polycarbonate (PC), and silicon. The substrate 32 can be a PCB (Printed Circuit Board).

[0055] At least one light source 34 may be mounted on the substrate 32. A plurality of light sources 34 may be spaced apart from each other on the substrate 32. Electrode patterns for connecting the adapter and the light source 34 may be formed on the substrate 32. For example, carbon nanotube electrode patterns for connecting the light source 34 and the adapter may be formed on the substrate 32.

[0056] For example, the light source 34 can be a light-emitting diode (LED) chip or an LED package including at least one LED chip. The light source 34 can be composed of colored LEDs emitting at least one color from red, green, blue, etc., or white LEDs. The colored LEDs can include at least one of red, green, and blue LEDs.

[0057] The reflector 36 may be located in front of the substrate 32. The reflector 36 may be located in an area other than the area where the light source 34 is formed on the substrate 32. The reflector 36 may have a hole 36a for providing the light source 34.

[0058] Furthermore, the reflector 36 may include at least one of a metal and a metal oxide as the reflective material. For example, the reflector 36 may include a metal and / or metal oxide with high reflectivity, such as at least one of aluminum (Al), silver (Ag), gold (Au), and titanium dioxide (TiO2). For example, resin may be deposited or coated on the light source 34 and / or the reflector 36. The resin can diffuse the light from the light source 34. Thus, the reflector 36 can reflect the light from the light source 34 or the light reflected from the diffuser plate 39 forward.

[0059] A diffuser plate 39 can be located in front of the reflector plate 36. The diffuser plate 39 can diffuse the light from the light source 34. A spacer 36b can be located between the reflector plate 36 and the diffuser plate 39, and can support the back of the diffuser plate 39. Thus, an air gap can be formed between the reflector plate 36 and the diffuser plate 39, and the light from the light source 34 can be diffused more widely through the air gap.

[0060] The optical sheet 40 can be located in front of the diffuser plate 39. The back side of the optical sheet 40 can be in close contact with the diffuser plate 39, and the front side of the optical sheet 40 can be in close contact with or adjacent to the back side of the display panel 10. The optical sheet 40 may include a diffuser sheet and / or a prism sheet.

[0061] Reference Figure 5 Board P can be attached to frame 60. Board P can be located between frame 60 and back cover 70, and can be attached to the back of frame 60. Multiple electronic components can be mounted on board P. Board P can be a PCB (Printed Circuit Board) and can be electrically connected to multiple electronic components of the display device.

[0062] The power supply board P1 supplies power to the various components of the display device. The motherboard P3 controls the various components of the display device. The timing controller board P2 can be connected to the motherboard P3 via a cable and provides image signals to the display panel 10.

[0063] Cable 11 can be adjacent to and electrically connected to the bottom edge of display panel 10. Cable 11 can pass through a slit SL or hole formed in frame 60. Source PCB 12 can be adjacent to the bottom edge of frame 60 and attached to the back of frame 60, and can be electrically connected to cable 11. Source PCB 12 can be electrically connected to timing control board P2 via cable.

[0064] Therefore, the timing control board P2 can provide digital video data and timing control signals to the display panel 10 through the source PCB12.

[0065] Reference Figure 1 The speaker 100 can be integrated with the frame 60. The speaker 100 can be located between the frame 60 and the rear cover 70, and can be integrated with the back of the frame 60. The speaker 100 can be adjacent to one side of the frame 60. The speaker 100 can be adjacent to the bottom edge of the frame 60, and can provide sound to the outside of the display device 1. For example, a plurality of speakers 100A, 100B can be integrated with the frame 60.

[0066] The sound device may include a configuration that integrates a speaker 100, a frame 60, and a retainer for the speaker 100 within the frame 60. The frame 60 may be the frame 60 of the aforementioned display device. Alternatively, the frame 60 may also be the frame of an audio device.

[0067] Reference Figure 6The speaker frame 101 can support a plurality of speaker units 100U of the speaker 100. The speaker 100 can be referred to as speaker assembly 100 or speaker module 100.

[0068] The first plate 102 can form one side of the speaker unit 100U. A pole piece 102a can protrude from the center of the first plate 102 and can have a hollow cylinder or solid cylinder shape. The second plate 103 can be spaced apart from the first plate 102 and can have a ring shape. A portion of the pole piece 102a can extend through the second plate 103, and an air gap can be formed between the second plate 103 and the pole piece 102a.

[0069] A magnet 104 can be disposed between the first plate 102 and the second plate 103, and can be ring-shaped. A portion of the pole piece 102a can pass through the magnet 104. A voice coil bobbin 105 can be located in the gap between the pole piece 102a and the second plate 103 and in the gap between the pole piece 102a and the magnet 104, and can have a hollow cylinder shape extending along the length of the pole piece 102a. A coil 106 can be formed or wound around the outer peripheral surface of the voice coil bobbin 105, and can be referred to as the voice coil 106. A terminal 107c and a tinsel wire 107d can transfer electrical energy from the amplifier output to the coil 106.

[0070] The spider 108 can be elastic. The spider 108 can be located between the voice coil frame 105 and the speaker frame 101, and can be combined with the voice coil frame 105 and the speaker frame 101. The spider 108 can support the voice coil frame 105 and can be called a damper 108.

[0071] One side of the diaphragm 107 can be attached to or bonded to the voice coil frame 105, and the other side of the diaphragm 107 can be supported by a flexible edge 107a. For example, the diaphragm 107 can have a cone or dome shape. A gasket 107b can be disposed on the side of the edge 107a to prevent the vibrating diaphragm 107 from interfering with surrounding structures. For example, a dust cap 109 can cover the central part of the diaphragm 107 to prevent dust and other contaminants from flowing into the magnetic circuit.

[0072] If magnetic field lines are formed in the gap using magnet 104 and current flows in coil 106, a Lorentz force can be generated. The magnitude of the Lorentz force can be proportional to the magnitude of the magnetic field lines (magnetic flux density), the amount of current, and the length of the wound coil, and the direction of the force can be perpendicular to the plane formed by the magnetic flux density and the current.

[0073] Therefore, the diaphragm 107 can vibrate along the length of the electrode 102a. If the diaphragm 107 moves upward, a positive (+) sound pressure can be generated; if the diaphragm 107 moves downward, a negative (-) sound pressure can be generated, and the speaker unit 100U can provide sound upward.

[0074] Reference Figure 7 and Figure 8 The loudspeaker assembly 100 may include a loudspeaker unit 100U and an enclosure 100E. The enclosure 100E may include a first enclosure 100Ea and a second enclosure 100Eb. The first enclosure 100Ea may be combined with the second enclosure 100Eb. The enclosure 100E may have an internal space. The enclosure 100E may include an inlet h and an outlet 100Eh. The inlet h and outlet 100Eh of the enclosure 100E may be connected through the internal space of the enclosure 100E. Sound flowing in through the inlet h may flow out through the outlet 100Eh.

[0075] The speaker unit 100U can be attached to or fixed to one side of the housing 100E. The inlet h of the housing 100E can face one side of the speaker unit 100U. For example, the inlet h of the housing 100E can be located behind the speaker unit 100U. The sound generated by the speaker unit 100U can flow in through the inlet h and then flow out through the internal space of the housing 100E to the outlet 100Eh. The direction in which the outlet 100Eh faces can be the direction in which the diaphragm 107 of the speaker unit 100U faces.

[0076] Reference Figure 9 The speaker frame 101 can be located on the opposite side of the speaker mount 101a relative to the magnet 104. The speaker mount 101a can form one side of the speaker unit 100U.

[0077] Magnet 104 can be disposed between speaker mount 101a and speaker frame 101, and can have a square shape. Diaphragm 107 can be attached to or fixed to speaker frame 101 using a flexible edge 107a. For example, diaphragm 107 can be a cone or dome shape with a major axis and a minor axis.

[0078] A dust cap 109 can cover the central portion of the diaphragm 107. The diaphragm 107 can vibrate. The diaphragm 107 can generate sound pressure through vibration. The speaker unit 100U can provide sound through sound pressure.

[0079] Reference Figure 10 The centering support 108 may include a centering support frame 1081, a voice coil skeleton hole 1083, and / or a vibrating part 1082. The centering support frame 1081 may be a track shape with a major axis and a minor axis. The centering support frame 1081 may be a closed loop or a plate shape. The voice coil skeleton hole 1083 may have a shape corresponding to the centering support frame 1081. The voice coil skeleton hole 1083 may be located inside the centering support frame 1081. The voice coil skeleton hole 1083 may be a track shape with a major axis and a minor axis or an ellipse.

[0080] The vibrating portion 1082 can be located between the centering support frame 1081 and the voice coil skeleton hole 1083. The voice coil skeleton hole 1083 can be formed by the vibrating portion 1082. The vibrating portion 1082 can have a plurality of folds. For example, the vibrating portion 1082 can have a plurality of peaks 1082a, 1082c, 1082e and a plurality of valleys 1082b, 1082d, 1082f between the voice coil skeleton hole 1083 and the centering support frame 1081.

[0081] The vibrating section 1082 may include a plurality of peaks 1082a, 1082c, 1082e and a plurality of valleys 1082b, 1082d, 1082f. The plurality of peaks 1082a, 1082c, 1082e may include a first peak 1082a, a second peak 1082c, and / or a third peak 1082e. The plurality of valleys 1082b, 1082d, 1082f may include a first valley 1082b, a second valley 1082d, and / or a third valley 1082f. Each of the plurality of valleys 1082b, 1082d, 1082f may be configured between each of the plurality of peaks 1082a, 1082c, 1082e. The first peak 1082a may be connected to the inner diameter of the centering support frame 1081. The first valley 1082b may be connected to the inner diameter of the first peak 1082a. The second peak 1082c can be connected to the inner diameter of the first valley 1082b. The second valley 1082d can be connected to the inner diameter of the second peak 1082c. The third peak 1082e can be connected to the inner diameter of the second valley 1082d. The third valley 1082f can be connected to the inner diameter of the third peak 1082e. The inner diameter of the third valley 1082f can form the voice coil skeleton hole 1083.

[0082] Therefore, the centering support 108 can use the centering support frame 1081 as a reference to make the voice coil skeleton hole 1083 vibrate and move along the thickness direction of the centering support 108.

[0083] The minor axis length Hd of the voice coil frame bore 1083 can be less than the minor axis length Dd of the centering support 108. This means that if the minor axis length Dd of the centering support 108 is shortened, the minor axis length of the voice coil frame bore 1083 will also be shortened. That is, through the loudspeaker unit 100U (refer to...) Figure 9 If the speaker unit 100U is thinner, the sound pressure level provided by the speaker unit can be reduced.

[0084] Reference Figure 11 and Figure 12 The first plate 102 can be attached to the speaker mounting base 101a. The first plate 102 can be located on the opposite side of the housing 100E relative to the speaker mounting base 101a. The pole piece 102a can protrude from the center of the first plate 102 and can be in the shape of a hollow cylinder or a solid cylinder.

[0096] The diameter Hd of the voice coil skeleton hole 1083 can be smaller than the spacing Dd between the plurality of cut edges CS of the centering support 108. In this case, the diameter Hd of the voice coil skeleton hole 1083 can be formed close to the spacing Dd between the plurality of cut edges CS of the centering support 108. That is, this means that the spacing Dd between the plurality of cut edges CS of the centering support 108 can be minimized, allowing the voice coil skeleton 105 (refer to...) to... Figure 21 The diameter of ) is the largest.

[0097] The voice coil frame 105 is inserted into the voice coil frame hole 1083 (see reference). Figure 21 The voice coil can be formed into a circle, increasing the intensity of the sound pressure generated by the voice coil frame 105 and the diaphragm 107. Simultaneously, the width of the centering support 108 is shortened, allowing the speaker unit 100U (refer to...) to... Figure 9 It can be made thin.

[0098] Reference Figure 15 and Figure 16 The centering support 108 may include a centering support frame 1081, a voice coil skeleton hole 1083, a vibrating part 1082, and / or a side reinforcement part 1085. There may be a plurality of centering support frames 1081. The centering support frames 1081 may form both sides of the centering support 108. For example, the centering support frame 1081 may be an arc-shaped plate. A first centering support frame 1081a may be located on the opposite side of the second centering support frame 1081b relative to the voice coil skeleton hole 1083.

[0099] The voice coil skeleton hole 1083 can be located in the center of the first centering support frame 1081a and the second centering support frame 1082b. The voice coil skeleton hole 1083 can be circular.

[0100] There can be a plurality of vibrating parts 1082. The first vibrating part 10821 can be located between the first centering support frame 1081a and the voice coil skeleton hole 1083. The second vibrating part 10822 can be located between the second centering support frame 1081b and the voice coil skeleton hole 1083.

[0101] The voice coil skeleton hole 1083 can be formed by the vibrating part 1082. The vibrating part 1082 can have a plurality of folds. For example, the vibrating part 1082 can have a plurality of peaks 1082a, 1082c, 1082e and a plurality of valleys 1082b, 1082d, 1082f between the voice coil skeleton hole 1083 and the centering support frame 1081.

[0102] The vibrating part 1082 may include a plurality of peaks 1082a, 1082c, 1082e and a plurality of valleys 1082b, 1082d, 1082f. The plurality of peaks 1082a, 1082c, 1082e may include a first peak 1082a, a second peak 1082c and / or a third peak 1082e. The plurality of valleys 1082b, 1082d, 1082f may include a first valley 1082b, a second valley 1082d and / or a third valley 1082f. Each of the plurality of valleys 1082b, 1082d, 1082f may be configured between each of the plurality of peaks 1082a, 1082c, 1082e to form a wave.

The second peak 1082c can be connected to the inner diameter of the first valley 1082b. The second valley 1082d can be connected to the inner diameter of the second peak 1082c. The third peak 1082e can be connected to the inner diameter of the second valley 1082d. The third valley 1082f can be connected to the inner diameter of the third peak 1082e. The inner diameter of the third valley 1082f can form the voice coil skeleton hole 1083.

[0104] The centering support 108 may include a voice coil skeleton hole 1083, a vibrating portion 1082, and / or a centering support frame 1081, and may be shaped by cutting off a portion of both sides of a circle plate from its annular shape. The centering support 108 may include side reinforcements 1085 forming the cutting edges of the centering support frame 1081 and / or the vibrating portion 1082. For example, the side reinforcements 1085 may form a wave in a linear direction. The centering support 108, with the centering support frame 1081 as a reference, causes the voice coil skeleton hole 1083 to vibrate and move along the thickness direction of the centering support 108. The side reinforcements 1085 can prevent the voice coil skeleton 105 (see reference 1081) from vibrating and moving. Figure 21 The rolling of the voice coil skeleton 105 (see reference) can guide the voice coil skeleton 105.

[0105] The diameter Hd of the voice coil skeleton hole 1083 can be smaller than the spacing Dd between the plurality of side reinforcements 1085a and 1085b of the centering support 108. In this case, the diameter Hd of the voice coil skeleton hole 1083 can be formed close to the spacing Dd between the plurality of side reinforcements 1085a and 1085b of the centering support 108. That is, this means that the spacing Dd between the plurality of side reinforcements 1085a and 1085b of the centering support 108 can be minimized, allowing the voice coil skeleton 105 (refer to...) to... Figure 12 The diameter of ) is the largest. Figure 16 The first difference between the interval Dd and the diameter Hd shown can be greater than Figure 13 The second difference between the interval Dd and the diameter Hd is shown.

[0106] Voice coil frame 105 inserted into voice coil frame hole 1083 (see reference) Figure 21 The voice coil can be formed into a circle, increasing the intensity of the sound pressure generated by the voice coil frame 105 and the diaphragm 107. Simultaneously, the width of the centering support 108 is shortened, allowing the speaker unit 100U (refer to...) to... Figure 9 It can be made thin.

[0107] Reference Figure 17The vibrating part 1082 may have amplitudes of peaks 1082a, 1082c, 1082e and valleys 1082b, 1082d, 1082f. For example, the amplitudes of the peaks 1082a, 1082c, 1082e and valleys 1082b, 1082d, 1082f of the vibrating part 1082 may be constant. As another example, the amplitudes of the peaks 1082a, 1082c, 1082e and valleys 1082b, 1082d, 1082f of the vibrating part 1082 may be variable.

[0108] The amplitudes of the first peak 1082a and the first valley 1082b can be greater than the amplitudes of the first valley 1082b and the second peak 1082c. The amplitudes of the first valley 1082b and the second peak 1082c can be greater than the amplitudes of the second peak 1082c and the second valley 1082d. The amplitudes of the second peak 1082c and the second valley 1082d can be greater than the amplitudes of the second valley 1082d and the third peak 1082e. The amplitudes of the second valley 1082d and the third peak 1082e can be greater than the amplitudes of the third peak 1082e and the third valley 1082f. Therefore, the vibration amplitude of the voice coil skeleton hole 1083 can be tuned in the thickness direction of the centering support 108.

[0109] The amplitudes of the first peak 1082a and the first valley 1082b can be smaller than the amplitudes of the first valley 1082b and the second peak 1082c. The amplitudes of the first valley 1082b and the second peak 1082c can be smaller than the amplitudes of the second peak 1082c and the second valley 1082d. The amplitudes of the second peak 1082c and the second valley 1082d can be smaller than the amplitudes of the second valley 1082d and the third peak 1082e. The amplitudes of the second valley 1082d and the third peak 1082e can be smaller than the amplitudes of the third peak 1082e and the third valley 1082f. Therefore, the vibration amplitude of the voice coil skeleton hole 1083 can be tuned in the thickness direction of the centering support 108.

[0110] The amplitudes of the first peak 1082a and the first valley 1082b can be equal to the amplitudes of the first valley 1082b and the second peak 1082c. The amplitudes of the first valley 1082b and the second peak 1082c can be equal to the amplitudes of the second peak 1082c and the second valley 1082d. The amplitudes of the second peak 1082c and the second valley 1082d can be equal to the amplitudes of the second valley 1082d and the third peak 1082e. The amplitudes of the second valley 1082d and the third peak 1082e can be equal to the amplitudes of the third peak 1082e and the third valley 1082f. Therefore, the vibration amplitude of the voice coil skeleton hole 1083 can be kept uniform in the thickness direction of the centering support 108.

[0111] Reference Figure 18 and Figure 19The side reinforcement 1085 may include a first side reinforcement 1085a and a second side reinforcement 1085b. The side reinforcement 1085 may be relative to the vibrating part 1082 (see reference). Figure 18 It is located on the opposite side of the voice coil skeleton hole 1083. The side reinforcement 1085 can form the edge of the side of the centering support 108.

[0112] The side reinforcement 1085 can be inclined downwards from the third peak 1082e. The amplitude A2 from the third peak 1082e to the edge of the side reinforcement 1085 can be greater than the amplitude A1 of the third peak 1082e and the third valley 1082f. For example, the amplitude A1 of the third peak 1082e and the third valley 1082f can be 1.5 to 2.5 mm, and the amplitude A2 from the third peak 1082e to the edge of the side reinforcement 1085 can be more than twice the amplitude A1 of the third peak 1082e and the third valley 1082f.

[0113] Therefore, the side reinforcement 1085 can maintain the rigidity of the side or edge of the centering support 108, and can ensure the vibration amplitude of the centering support 108.

[0114] Reference Figure 20 and Figure 21 The electrode 102a may protrude from the center of the first plate 102 and may be in the shape of a hollow cylinder or a solid cylinder. The electrode 102a may be cylindrical and may have a circular cross-section. The second plate 103 may be spaced apart from the first plate 102 and may be in the shape of a disk or a ring. A portion of the electrode 102a may penetrate through the second plate 103, and an air gap may be formed between the second plate 103 and the electrode 102a.

[0115] Magnet 104 can be disposed between the first plate 102 and the second plate 103, and can be in the shape of a ring or a doughnut. A portion of pole piece 102a can pass through magnet 104. Voice coil skeleton 105 can be located in the gap between pole piece 102a and the second plate 103 and in the gap between pole piece 102a and magnet 104, and can have a hollow cylinder shape extending along the length direction of pole piece 102a. Voice coil skeleton 105 can have a ring-shaped or a doughnut-shaped cross-section.

The speaker frame 101 can include a centering support mounting base 110. The centering support mounting base 110 can be coupled to the second plate 103. The centering support mounting base 110 can be coupled to the speaker frame 101. The centering support mounting base 110 can be located at the periphery of the voice coil frame 105. The centering support 108 can be fixed to the centering support mounting base 110. The centering support frame 1081 of the centering support 108 can be fixed to the centering support mounting base 110.

[0118] For example, the voice coil frame 105 can be inserted into the voice coil frame hole 1083 of the centering support 108 and supported by the vibrating part 1082. Alternatively, the voice coil frame 105 can be inserted into or pressed into the voice coil frame hole 1083 of the centering support 108. Another example is that the voice coil frame hole 1083 can be engaged and fixed to the outer surface of the voice coil frame 105. Thus, the centering support 108 can suppress the rolling of the voice coil frame 105.

[0119] One side of the diaphragm 107 can be attached to or bonded to the voice coil frame 105, and the other side of the diaphragm 107 can be supported by a flexible edge 107a. The diaphragm 107 can vibrate along the length of the electrode 102a to produce sound.

[0120] Reference Figures 22 to 24 The centering support 108 can reciprocate or vibrate together with the voice coil frame 105. The centering support 108 can be located between the voice coil frame 105 and the speaker frame 101. The centering support 108 can support the voice coil frame 105.

[0121] For example, the voice coil frame 105 can be inserted into the voice coil frame hole 1083 of the centering support 108 and supported by the vibrating part 1082. Alternatively, the voice coil frame 105 can be inserted into or pressed into the voice coil frame hole 1083 of the centering support 108. Another example is that the voice coil frame hole 1083 can be engaged and fixed to the outer surface of the voice coil frame 105. Thus, the centering support 108 can suppress the rolling of the voice coil frame 105.

[0122] The side reinforcement 1085 of the centering support 108 can be separated from the inner surface of the speaker frame 101. A first gap G1 can be formed between the first side reinforcement 1085a of the centering support 108 and the inner surface of the speaker frame 101. A second gap G2 can be formed between the second side reinforcement 1085b of the centering support 108 and the inner surface of the speaker frame 101. If the centering support 108 vibrates, the edge of the side reinforcement 1085 of the centering support 108 can vibrate as a free end. At this time, under the action of the side reinforcement 1085, the centering support 108 can suppress the rolling of the voice coil frame 105 without reducing the amplitude of the vibration system.
