  Next, as shown in FIGS. 1 and 2, the lower frame 39 holds down the middle frame 37 that holds the liquid crystal panel 2, the sounding body 3, and the support body 49 that supports the sounding body 3 so as to cover from the lower side in the figure. A sound emitting hole 51 for emitting sound generated from the sounding body is provided in the approximate center of the bottom 50 of the lower frame 39 with which the support 49 abuts.

  The frame body 6 is not limited to the structure divided into the upper frame 38, the middle frame 37, and the lower frame 39 as described above. For example, the upper frame, the middle frame, and the lower frame are integrally formed to form one frame. It may constitute a body. As a result, it is possible to prevent rattling caused by vibration from the sounding body 3 at a lower cost with a wider variety of liquid crystal devices with a sounding body. Further, the frame body may be a metal frame made of a metal material, whereby a spring can be formed easily and at low cost.

  (Manufacturing method of liquid crystal device with sound generator)

  Next, a manufacturing method of the liquid crystal device with a sounding body will be briefly described.

  First, the liquid crystal panel 2 is manufactured.

  ITO or the like, which is a material for the common electrode 11, is deposited on the first substrate 8 by sputtering, patterned by photolithography, and striped in the X-axis direction as shown in FIGS. 11 is formed. Further, an overcoat layer 12 is formed thereon, an alignment film 13 is further formed thereon, and a rubbing process is performed to form the first substrate side.

  Next, similarly, the segment electrodes 15 are formed in a stripe shape in the Y-axis direction as shown in FIGS. 1 and 2 on the second substrate 9, and the overcoat layer 16 and the alignment film 17 are further formed. The substrate side is formed. When the segment electrode 15 is formed, the external terminal 20 of the overhang portion 19 may be formed at the same time.

  Then, the gap material 53 is sprayed on the first substrate 8 by dry spraying or the like, and the first substrate 8 and the second substrate 9 are bonded together via the seal material 7. Thereafter, the liquid crystal 10 is injected from an opening (not shown) of the sealing material 7, and the opening of the sealing material 7 is sealed with a sealing material such as an ultraviolet curable resin.

  Next, the flexible substrate 4 is manufactured.

  After forming a predetermined wiring pattern 25, a main body connecting terminal 29, a branch connecting terminal 31, a connecting terminal and the like on the base substrate 24 formed by the mold of the main body 27 and the branch 28, A liquid crystal driving IC is mounted on the connection terminal of the main body 27 via the ACF.

  Further, the main body connection terminal 29 of the flexible substrate 4 on which electronic components are mounted is electrically connected to the external terminal 20 of the liquid crystal panel 2 via the external ACF 30. Similarly, the branch connection terminal 31 is electrically connected to the sound generator terminal 22 of the sound generator 3 via the external ACF 30.

  Next, the support body 49 is set in the lower frame 39 so that the sound emission hole 51 is located at the inner center of the support body 49. The sounding body main body 21 is placed on the sounding body main body 21, the sounding body main body 21, the sounding body terminal portion 23, and the electrically connected branch portion 28 so that they are held in the sounding body containing portion 41. Store and set the inner frame 37. When the sounding body 3 is set on the lower frame 39 and the middle frame 37, the branch portion 28 of the flexible substrate 4 is inserted through the lower frame guide groove 52 and the middle frame guide groove 42, respectively.

  Further, for example, as shown in FIGS. 1 and 2, the reflection sheet 36, the light guide plate 33 to which the light source 32 is attached, the diffusion sheet 35, and the two prism sheets 34 and 34 are arranged in that order in the middle frame recess 40 of the middle frame 37. The liquid crystal panel 2 to which the main body 27 of the flexible substrate 4 is connected is placed thereon from the bottom in the figure.

  Next, the upper frame 38 is set on the lower frame 39 so as to cover the middle frame 37 in which the liquid crystal panel 2, the sounding body 3 and the like are accommodated. At this time, the main body 27 on the main body connecting terminal 29 side of the flexible substrate 4 electrically connected to the external terminal 20 of the liquid crystal panel 2 through the external ACF 30 is passed through the upper frame recess 48. In addition, other necessary parts are attached to complete the liquid crystal device 1 with a sounding body.

  Further, the completed sound generator-equipped liquid crystal device 1 is arranged inside a case 54 which is a casing of an electronic device such as a mobile phone as shown in FIG.

  For example, as shown in FIG. 7, a display opening 55 corresponding to the opening 43 of the upper frame 38 is provided on the display side of the liquid crystal panel 2 of the case 54, and the lower frame 39 is released on the opposite side. A sound emission opening 56 is provided at a position corresponding to the sound hole 51.

  Furthermore, the case 54 fixes the frame 6 (the liquid crystal device 1 with a sounding body) inside the case 54 via a support 57 as shown in FIG. Thereby, since the frame 6 is firmly fixed to the case 54, it can be prevented from resonating due to vibration from the sounding body, like the liquid crystal panel or the like.

  (Operation of LCD device with sound generator)

  Next, the operation of the liquid crystal device with a sounding body 1 configured as described above will be briefly described focusing on the movement of the spring.

  First, when there is no play between the parts, for example, the spring 46a of the upper frame 38 is shown in FIG. 6 (b) before the upper frame 38 is set on the middle frame 37, the lower frame 39, etc. as shown in FIG. As shown in FIG. 2, only C protruded, but after setting, it was completely pushed into the same position as the surface of the upper frame 38, and the springs 46b and 46c were pushed slightly into the hole 47 as shown in FIG. ing.

  However, when a play (for example, D in FIG. 8) occurs between the parts, the vibration from the sounding body 3 resonates in the play and the noise is generated, but for example, as shown in FIG. Since the liquid crystal panel 2 is pressed by the middle frame recess 40 which is a contact portion by at least elastic deformation of the spring 46a, the spring absorbs the shakiness of the liquid crystal panel 2, and the shakiness is less than when there is no spring. It becomes possible to make it smaller.

  Further, since the middle frame 37 is also pressed by the elastic deformation as shown in FIG. 8 by the springs 46b and 46c, it is possible to absorb and hold the rattling of the middle frame and the like. As a result, even if there is some backlash between the components, rattling can be suppressed by elastic deformation of the spring, so that it is possible to suppress resonance of vibration from the sounding body 3.

  Above, description of operation | movement of the liquid crystal device 1 with a sounding body is completed.

  As described above, according to the present embodiment, a part of the sounding body is formed by the vibration from the sounding body 3 by using the spring part 44 as a part and pressing the liquid crystal panel 2 against the abutting part side, for example, the inner frame concave part 40 using the elastic deformation. Since the frame 6 capable of suppressing the shakiness of the attached liquid crystal device or the like is provided, the shakiness that occurs between the parts such as the liquid crystal panel 2 due to variations in parts tolerance is absorbed by its elastic deformation. And the generation of abnormal noise due to vibration resonance from the sounding body 3 can be prevented. In addition, instead of providing a new member separately from the frame body 6, a part of the conventional frame body itself is made elastically deformable as a spring structure, so that abnormal noise is generated due to resonance without increasing the number of parts. Can be prevented.

  Furthermore, since the frame 6 has the upper frame 38 having the spring portions 44 (44a, 44b, 44c) on part of the two opposite sides, the liquid crystal panel 2 can be pressed from the display side by using, for example, the spring 46a. In addition, since the middle frame 37 itself can be pressed using the springs 46b and 46c, not only the relationship between the liquid crystal panel 2 and the middle frame 37 but also the relationship between the upper frame 38 and the middle frame 37 Absorption can be absorbed.

  (Second Embodiment)

  Next, a second embodiment of the liquid crystal device with a sounding body according to the present invention will be described. This embodiment is different from the first embodiment in that the spring is not formed as a part of the upper frame but is formed as a part of the middle frame, and this point will be mainly described. In addition, about the component which is common in the component of 1st Embodiment, the code | symbol same as the component of 1st Embodiment is attached | subjected, and the description is abbreviate | omitted.

The flexible substrate 4 further includes a frame body 106 that integrally holds the liquid crystal panel 2, the sounding body 3, and the like. Here, in addition to the frame body 106, other auxiliary mechanisms are attached to the liquid crystal device 101 with the sounding body as needed (not shown).

  For example, as shown in FIG. 9, the frame 106 includes a middle frame 137 as a second frame for holding the liquid crystal panel 2 and an upper frame 138 as a first frame for holding the liquid crystal panel 2 and the middle frame 137 from above. And a lower frame 39 as a third frame held from below (from the side opposite to the liquid crystal panel side).

  Here, the middle frame 137 has a rectangular box shape as shown in FIGS. 9 and 10, for example, and houses a part of the liquid crystal panel 2 on the illumination device 5 side (the Z-axis upward direction in the drawing) There are a middle frame recess 140 to be held, a sounding body housing portion 141 for housing the sounding body 3 which is a recess provided on the opposite side, a middle frame guide groove 42 through which the branch portion 28 of the flexible substrate 4 passes.

  The sounding body accommodating portion 141 accommodates the sounding body 3 such that the sounding body terminal portion 23 faces the middle frame guide groove 42 in the Y-axis direction as shown in FIG. 9, for example. Of course, the sounding body 3 may be housed and held so as to face the corner of the sounding body housing portion 141 as in the first embodiment.

  Further, as shown in FIGS. 9, 10 and 11, the middle frame 137 has spring portions 144 as elastic deformation portions on two opposite sides of the rectangular middle frame recess 140. For example, the liquid crystal panel 2 has one (144a) on the projecting side and two springs (144b, 144c) on the opposite sides.

  Here, the spring portion 144a is formed by two punched rectangular holes 145, 145 formed, for example, by punching as shown in FIGS. 9, 10, and 11 at the substantially central side of the inner frame recess 140 on the flexible substrate side. Have

  Furthermore, the spring portion 144a is elastic on the illuminating device side (upper side in the drawing) as shown in FIG. 9 and FIG. 11 in the band-shaped portion that is a part of the middle frame 137 between the two holes 145, 145 arranged side by side. A projecting spring 146a is provided.

  Further, the spring portion 144b has a substantially U-shaped hole 147 formed by punching, for example, as shown in FIG. 11 at a side corner of the middle frame recess 140 opposite to the flexible substrate.

  Further, the spring portion 144b elastically protrudes a tongue-shaped portion, which is a part of the middle frame 137 formed by the hole 147, toward the lighting device side (upper side in the drawing) as shown in FIGS. A spring 146b is provided as a rising portion. Further, although only a part is shown in FIG. 9, as shown in FIG. 11, the spring portion 144c is opposite to the opposite corner of the middle frame recess 140 facing the spring portion 144b, and the spring portion 144b and the spring 146c are reversed left and right. Thus, they are formed to face each other.

  Next, for example, as shown in FIG. 9, the upper frame 138 holds the liquid crystal panel 2 held by the middle frame 137 by pressing the liquid crystal panel 2 together with the middle frame 137 at a contact portion as a contact portion so as to cover from the upper side in the drawing. An opening 43 serving as a liquid crystal display surface is provided substantially at the center of the outer surface.

  Further, as shown in FIG. 9, the upper frame 138 has an upper frame recess 48 formed on the side surface on the flexible substrate side so that the main body connection terminal 29 side of the main body portion 27 of the flexible substrate 4 can be inserted. Unlike the first embodiment, the spring portion is not formed. Of course, you may form a spring part similarly to 1st Embodiment. Thereby, the rattling between components can be suppressed and resonance from the vibration of the sounding body 3 can be prevented.

  (Manufacturing method of liquid crystal device with sound generator)

  Since the manufacturing method of the liquid crystal device 101 with a sounding body according to the present embodiment is the same as that of the first embodiment, the description thereof is omitted.

  (Operation of LCD device with sound generator)

  Next, the operation of the sound generator-equipped liquid crystal device 101 configured as described above will be briefly described focusing on the movement of the spring.

  First, when there is no backlash between the components, for example, the spring 146a of the middle frame 137 is shown in FIGS. 9 and 10 before the upper frame 138 is set on the middle frame 137, the lower frame 39, etc. as shown in FIG. However, after setting, the springs 146b and 146c are also the same as the surface of the surrounding middle frame recess 140 in the same manner. Is pushed into position.

  However, when a play (for example, F in FIG. 12) occurs between the parts, the vibration from the sounding body 3 resonates in the play as it is, but an abnormal sound is generated. For example, as shown in FIG. At least the liquid crystal panel 2 is pressed against the contact portion with the liquid crystal panel as the contact portion of the upper frame 138 using the elastic deformation of the springs 146a, 146b, 146c, so that the spring absorbs the shakiness of the liquid crystal panel 2. It is possible to make the rattling smaller than when there is no spring.

  This is the end of the description of the operation of the sound generator-equipped liquid crystal device 101.

  As described above, according to the present embodiment, a part of the middle frame 137 is the spring portion 144, and the elastic deformation is used to press the liquid crystal panel 2 toward the contact portion side of the upper frame that is the first frame. Since the frame body 106 capable of suppressing the shakiness of the liquid crystal panel or the like due to vibration from the body 3 is provided, rattling that occurs between the parts of the sounding body-equipped liquid crystal device 101 due to variations in part tolerances. Absorption can be absorbed by the elastic deformation, and generation of abnormal noise due to vibration resonance from the sounding body 3 can be prevented. In addition, instead of providing a new member separately from the middle frame 137, a part of the conventional middle frame itself is made elastically deformable as a spring structure, so that abnormal noise is generated due to resonance without increasing the number of parts. Can be prevented.

  (Third embodiment)

  Next, a third embodiment of the liquid crystal device with a sounding body according to the present invention will be described. This embodiment is different from the first embodiment in that the spring is not formed as a part of the upper frame but is formed as a part of the middle frame, and this point will be mainly described. In addition, about the component which is common in the component of 1st Embodiment, the code | symbol same as the component of 1st Embodiment is attached | subjected, and the description is abbreviate | omitted.

Here, in addition to the frame body 206, other incidental mechanisms are attached to the liquid crystal device with sound generator 201 as needed (not shown).

  For example, as shown in FIG. 13, the frame body 206 includes a middle frame 237 as a second frame for holding the liquid crystal panel 2 and an upper frame 238 as a first frame for holding the liquid crystal panel 2 and the middle frame 237 from above. And a lower frame 39 as a third frame held from below (from the side opposite to the liquid crystal panel side).

  Here, the middle frame 237 has a rectangular box shape as shown in FIGS. 13 and 14, for example, and houses a part of the liquid crystal panel 2 on the illumination device 5 side (the Z-axis upward direction in the drawing) There are a middle frame recess 240 to be held, a sounding body housing portion 241 for housing the sounding body 3 which is a recess provided on the opposite side, a middle frame guide groove 42 through which the branch portion 28 of the flexible substrate 4 passes.

  The sounding body accommodating portion 241 accommodates the sounding body 3 so that the sounding body terminal portion 23 faces the middle frame guide groove 42 in the Y-axis direction as shown in FIG. Of course, the sounding body 3 may be housed and held so as to face the corner of the sounding body housing portion 241 as in the first embodiment.

  Further, the middle frame 237 has spring portions 244 (244a, 244b, 244c) as elastic deformation portions on two opposite sides of the rectangular middle frame recess 240 as shown in FIGS. For example, one (244a) is provided on the projecting portion side of the liquid crystal panel 2, and two spring portions (244b, 244c) are provided on opposite sides thereof.

  Here, the spring portion 244a has two aligned rectangular holes 245 and 245 formed, for example, by punching as shown in FIGS. 13, 14 and 15 at the center of the side of the inner frame recess 240 on the flexible substrate side. Have

  Further, the spring portion 244a is elastic to the illuminating device side (upper side in the drawing) as shown in FIGS. 13 and 15 with a belt-like portion that is a part of the middle frame 237 between the two holes 245 and 245 arranged side by side. A projecting spring 246a is provided.

  Further, the spring portion 244b has a substantially U-shaped hole 247 formed by punching, for example, as shown in FIG. 15 at a side corner of the middle frame recess 240 opposite to the flexible substrate.

  Further, the spring portion 244b elastically protrudes a tongue-shaped portion, which is a part of the middle frame 237 formed by the hole 247, toward the lighting device side (upper side in the drawing) as shown in FIGS. A spring 246b is provided as a rising portion. Further, although only a part is shown in FIG. 13, as shown in FIG. 15, the spring portion 244c is opposite to the middle frame recess 240 facing the spring portion 244b, and the spring portion 244b and the spring 246c are reversed left and right. Thus, they are formed to face each other.

  The middle frame 237 includes a frame-shaped middle frame convex portion 255 formed around the middle frame concave portion 240, and spring portions 244 ′ (244 a ′, 244 a ′, 244b ′, 244c ′). For example, the liquid crystal panel 2 has one (244a ′) on the opposite side of the projecting portion side and two spring portions (244b ′, 244c ′) on the projecting portion side.

  Here, the spring portion 244a ′ is formed in two side-by-side rectangular shapes formed by punching, for example, as shown in FIGS. 13, 14, and 15 at the substantially central side of the middle frame convex portion 255 opposite to the flexible substrate side. Holes 245 'and 245'.

  Further, the spring portion 244a ′ is elastic on the upper frame side (upper side in the drawing) as shown in FIG. 13 in the belt-like portion that is a part of the middle frame 237 between the two holes 245 ′ and 245 ′ arranged side by side. And a spring 246a 'that is protruded from the center.

  Further, the spring portion 244b ′ has a substantially U-shaped hole 247 ′ formed by punching, for example, as shown in FIG. 13 and FIG.

  Further, the spring portion 244b ′ has a belo-shaped portion which is a part of the middle frame 237 formed by the hole 247 ′ elastically toward the upper frame side (upper side in the drawing) as shown in FIGS. A spring 246 b ′ is provided as a raised portion that is protruded in a continuous manner. Further, as shown in FIG. 13 and FIG. 15, the spring portion 244c ′ is opposite to the opposite corner of the middle frame convex portion 255 facing the spring portion 244b ′, and the spring portion 244b ′ and the spring 246c ′ are horizontally reversed. It is formed to face. When the spring portion 244 ′ is formed on the middle frame convex portion 255, the lower portion of the spring portion 244a ′ in FIG. 14 is hollowed to form the spring portion 244a ′ as in the spring 246a ′ shown in FIG. The thickness of the portion of the frame convex portion 255 is reduced to form the spring portion 244a ′. The same applies to the spring portions 244b ′ and 244c ′. As a result, the spring can be formed more easily.

  Next, for example, as shown in FIG. 13, the upper frame 238 holds the liquid crystal panel 2 held by the middle frame 237 by pressing the liquid crystal panel 2 together with the middle frame 237 at a contact portion as a contact portion so as to cover from the upper side in the drawing. An opening 43 serving as a liquid crystal display surface is provided substantially at the center of the outer surface.

  Further, as shown in FIG. 13, the upper frame 238 is formed with an upper frame concave portion 48 on the side surface on the flexible substrate side so that the main body connecting terminal 29 side of the main body portion 27 of the flexible substrate 4 can be inserted. Unlike the first embodiment, the spring portion is not formed. Of course, you may form a spring part similarly to 1st Embodiment. As a result, rattling between components of a variety of sounding body-equipped liquid crystal devices can be suppressed and resonance from vibration of the sounding body 3 can be prevented.

  Next, a modified example will be described.

  FIG. 17 is an explanatory diagram of a modification of the planar arrangement of the spring part in the upper frame, FIG. 18 is an explanatory diagram of a modification of the planar arrangement of the spring part in the middle frame, and FIG. 19 is an explanation of the modification of the spring shape. FIG.

  The planar arrangement of the spring part is not limited to the side on the flexible substrate 4 side and the side on the opposite side as described above. For example, as shown in FIGS. It may be provided on two opposite sides (X-axis direction side in the drawing).

  For example, as shown in FIG. 17, two opposite sides of the upper frame 438 as the first frame that are different from the flexible substrate 4 side, and a spring portion 444 a as an elastically deforming portion on the upper side in the figure as a part of the upper frame 438. The spring portions 444b and 444c as elastic deformation portions are formed as a part of the upper frame 438 on the lower side.

  Specifically, the spring portion 444 a has a rectangular hole 445 formed, for example, by punching inward from the opening 43, and a part of the belt-like upper frame 438 between the hole 445 and the opening 43. Are elastically projected toward the liquid crystal panel or the inner frame to form a spring 446a.

  The spring portions 444b and 444c are formed by punching a substantially U-shaped hole 447 so as to face corners of opposite sides (lower side in the figure), and a bell-shaped upper frame 438 formed by the hole 447. Are elastically projected toward the liquid crystal panel or the middle frame, and springs 446b and 446c as rising portions are formed.

  Further, as shown in FIG. 18, also in the middle frame 537 as the second frame, two opposite sides (X-axis direction side in the figure) of the middle frame recess 540 as the contact portion which are different from the flexible substrate 4 side. A spring portion 544a as an elastic deformation portion may be formed as a part of the middle frame 537 on the lower side in a certain figure, and spring portions 544b and 544c as elastic deformation portions may be formed on the upper side.

  Specifically, the spring portion 544a is formed with rectangular holes 545 and 545 arranged in the Y-axis direction in the figure by punching, for example, at a position slightly inside from the outer periphery of the middle frame recess 540, and the two holes A part of the belt-like middle frame 537 between 545 and 545 is elastically projected toward the liquid crystal panel to form a spring 546a.

  Each of the spring portions 544b and 544c is formed by punching a substantially U-shaped hole 547 at the corner of the opposite side (upper side in the drawing), and a part of the bevel-shaped inner frame 537 formed by the hole 547 is formed. Springs 546b and 546c as rising portions are formed by elastically projecting toward the liquid crystal panel.

  Further, the spring portion is not limited to the case where a substantially U-shaped hole is punched as shown in FIG. 5 to form a tongue-like spring. For example, as shown in FIG. The spring portion 644b can also be formed by leaving only one of the three sides and elastically projecting the portion surrounded by the three cut out sides to form the spring 646b. This is advantageous when the spring portion is formed in a narrower place.

  Similarly, the spring portion is not limited to the case where a spring is formed by punching out one or two rectangular holes and elastically projecting a part of a belt-like frame, and FIG. As shown in Fig. 1, one or two parallel cuts are made in parallel, and a part of the belt-like frame between the cuts is elastically projected to form a spring 646a as a convex portion. A portion 644a can be formed. Of course, the incision is not limited to the above case, and may be an incision of a non-parallel curve. Thereby, the elastic deformation part which can be elastically deformed in a narrower space can be formed.

  The above-described planar arrangement of the spring part and the modification of the shape of the spring part are not limited to the present embodiment, and can be similarly applied to the first and second embodiments. As a result, it is possible to suppress rattling due to variations in component tolerances in various liquid crystal devices with sound generators, and to prevent generation of abnormal noise.

  (Manufacturing method of liquid crystal device with sound generator)

  Since the manufacturing method of the liquid crystal device 201 with a sounding body according to the present embodiment is substantially the same as that of the first embodiment, the description thereof is omitted.

  (Operation of LCD device with sound generator)

  Next, the operation of the sound generator-equipped liquid crystal device 201 configured as described above will be briefly described focusing on the movement of the spring.

  First, when there is no play between the parts, for example, the spring 246a of the middle frame 237 is as shown in FIG. 13 before the upper frame 238 is set on the middle frame 237, the lower frame 39, etc. as shown in FIG. However, after setting, the springs 246b and 246c are also pushed into the same position as the surface of the surrounding middle frame recess 240 in the same manner. It is.

  Further, the springs 246a ', 246b' and 246c 'are in contact with the upper frame 238 as shown in FIG.

  However, when there is a backlash (for example, H in FIG. 16) between the parts, the vibration from the sounding body 3 resonates in the backlash as it is, but an abnormal sound is generated. For example, as shown in FIG. Since the liquid crystal panel 2 is pressed against the contact portion with the liquid crystal panel as the contact portion of the upper frame 238 using the elastic deformation of the springs 246a, 246b, 246c, the spring absorbs the shakiness of the liquid crystal panel 2. It is possible to make the rattling smaller than when there is no spring.

  Further, since the play (H in the figure) of the upper frame 238 is pressed by the elastic deformation of the springs 246a ′, 246b ′ and 246c ′, the spring absorbs rattling between the upper frame 238 and the middle frame 237, for example. In addition, resonance due to vibration from the sounding body 3 can be prevented.

  Above, description of operation | movement of the liquid crystal device 201 with a sounding body is complete | finished.

  As described above, according to the present embodiment, a part of the middle frame 237 serves as the spring portion 244, and the liquid crystal panel 2 is pressed against the contact portion of the upper frame 238, which is the first frame, using the elastic deformation. Since the frame body 206 capable of suppressing, for example, shakiness of a liquid crystal panel or the like due to vibration from the body 3 is provided, rattling occurring between the parts of the sounding body-equipped liquid crystal device 201 due to variation in part tolerance. Can be absorbed by the elastic deformation, and generation of abnormal noise due to resonance of vibration from the sounding body 3 can be prevented. In addition, instead of providing a new member separately from the middle frame 237, a part of the conventional middle frame itself is made elastically deformable as a spring structure, so that abnormal noise is generated due to resonance without increasing the number of parts. Can be prevented.

  Further, since the middle frame 237 is provided with spring portions in both the middle frame concave portion 240 and the middle frame convex portion 255, the upper frame 238 itself can be pressed by the spring of the middle frame convex portion 255. Thereby, not only the relationship between the liquid crystal panel 2 and the middle frame 237, but also the relationship between the upper frame 238 and the middle frame 237 can be absorbed.

  Further, by forming two types of springs 246a, 246b and 246c that contact the liquid crystal panel 2 and springs 246a ′, 246b ′ and 246c ′ that contact the upper frame 238, two types of spring strength can be provided. Thereby, for example, in order to ensure the performance of the liquid crystal panel 2, the elastic force of the springs 246a, 246b and 246c can be made relatively weaker than the springs 246a ′, 246b ′ and 246c ′.

In addition, instead of providing a new member separately from the frame body 6, a part of the conventional frame body itself is made elastically deformable as a spring structure, so that abnormal noise is generated due to resonance without increasing the number of parts. Can be prevented.

  Further, since the frame 6 is housed integrally with the liquid crystal panel 2, the illumination device 5 and the sounding body 3, the acoustic design and the like can be made in advance as a liquid crystal device with a sounding body, and it is smaller and easier to produce a high quality sounding body.
