Description

  The present invention relates to a display device and a speaker, and more particularly to a display device and a speaker arranged side by side in the same direction.

  As shown in FIG. 1, the speaker of a thin television receiver is often provided on the lower side of the display screen or on the side of the display screen.

  In recent years, television receivers are arranged side by side in the same direction, left and right or up and down, and these television receivers can display individual images as a whole, or display an enlarged image as desired. A technique of dividing and displaying an image with a size of 3 mm has been used.

  Conventionally, when a television broadcast program is displayed on a television receiver as a master unit, when a scene change occurs in the image data displayed on the master unit, the image data of the frame immediately after the scene change is When a scene change occurs in the image data displayed on the television receiver as the slave unit and then further displayed on the master unit, the image data of the frame immediately after the scene change is displayed on the slave unit until now. Some images are displayed instead of the image data that has been stored (see, for example, Patent Document 1).

JP 2004-289866 A

  However, when a television receiver provided with a speaker beside the display screen or on the lower side is arranged side by side in the same direction on the left and right or up and down to display one image as a whole, as shown in FIG. The gap of the image is made as much as the width of the speaker, and this gap hinders viewing of the image.

  Although it is conceivable that the speaker can be removed from the television receiver, if the speaker is removed, the sound cannot be heard.

  If a speaker is provided separately from the television receiver, sound can be heard from a position away from the image.

  In addition, if the speaker is simply placed behind the television receiver, sound can be output from the gap between the television receivers, but the volume is reduced and the position where the displayed image is viewed. Makes it difficult to hear sound.

  Further, when the television receivers with the speakers arranged behind are adjacent to each other, the speakers face each other. In this state, if audio is output from only one of the opposing speakers, the volume is halved compared to when audio is output from both speakers, and stereo audio is output to both of the opposing speakers. If it does, the phase and level of the sound will be different, so they will cancel each other out and the volume will be reduced.

As shown in FIG. 3, the monitor devices 11-1 to 11-9, which are examples of display devices, are arranged in three rows horizontally and three columns vertically. In other words, the monitor devices 11-1 to 11-3 are arranged side by side at the same height, adjacent to each other in the order from the left, and facing the front.

  The monitor devices 11-4 to 11-6 are arranged below the monitor devices 11-1 to 11-3 in order from the left, adjacent to each other at the same height, and facing the front. In addition, the monitor devices 11-7 to 11-9 are arranged below the monitor devices 11-4 to 11-6 in order from the left, adjacent to each other at the same height, and facing the front.

  In other words, the monitor devices 11-1 to 11-3 are sequentially arranged in one horizontal row, the monitor devices 11-4 to 11-6 are sequentially arranged in one horizontal row, and the monitor devices 11-7 to 11-9 are sequentially arranged. The monitor device 11-1, the monitor device 11-4, and the monitor device 11-7 are arranged in one vertical column in order, and the monitor device 11-2, the monitor device 11-5, and the monitor device. 11-8 are sequentially arranged in one vertical column, and the monitor device 11-3, the monitor device 11-6, and the monitor device 11-9 are sequentially arranged in one vertical column.

  Each of the monitor devices 11-1 to 11-9 displays an individual image, enlarges and displays one image as a whole, or divides and displays an image in a desired size.

  The monitor devices 11-1 to 11-9 output the sound of one image among the displayed images.

  Hereinafter, the monitor devices 11-1 to 11-9 will be referred to as the monitor device 11 as a unit when it is not necessary to distinguish them individually.

  Next, the structure of the monitor device 11 will be described.

  FIG. 4 is a rear view of the monitor device 11, FIG. 5 is a top view of the monitor device 11, and FIG. 6 is a side view of the monitor device 11.

  The speakers 31-1 to 31-4 are arranged forward on the rear side of the display surface for displaying an image. That is, the speakers 31-1 to 31-4 are arranged on the rear side of the display surface so that sound output in front of the monitor device 11 is radiated.

  When the monitor device 11 is viewed from the back side, the speaker 31-1 is provided on the upper right side of the back side of the monitor device 11, and the speaker 31-2 is provided on the lower right side of the back side of the monitor device 11. When the monitor device 11 is viewed from the back surface side, the speaker 31-3 is provided at the upper left of the back surface of the monitor device 11, and the speaker 31-4 is provided at the lower left of the back surface of the monitor device 11.

  More specifically, as shown in FIG. 5, when the monitor device 11 is viewed from above, the propagation direction of the sound radiated from the speaker 31-1 (the direction indicated by the arrow) is the method of the display surface of the monitor device 11. When the monitor device 11 is viewed from the side as shown in FIG. 6, the propagation direction of the sound emitted from the speaker 31-1 (the direction indicated by the arrow) ) Is parallel to the normal of the display surface of the monitor device 11, the speaker 31-1 is provided in the monitor device 11.

  Similarly, when the monitor device 11 is viewed from above, the propagation direction of the sound radiated from the speaker 31-2 is a predetermined angle (speaker 31-1) in the clockwise direction with respect to the normal line of the display surface of the monitor device 11. As shown in FIG. 6, when the monitor device 11 is viewed from the side, the propagation direction of the sound radiated from the speaker 31-2 is determined by the method of the display surface of the monitor device 11. The speaker 31-2 is provided in the monitor device 11 so as to be parallel to the line.

  That is, the sound from the speaker 31-1 and the speaker 31-2 is radiated obliquely forward from the left vertical end when the monitor device 11 is viewed from the front.

  Further, as shown in FIG. 5, when the monitor device 11 is viewed from above, the propagation direction of the sound radiated from the speaker 31-3 is counterclockwise with respect to the normal line of the display surface of the monitor device 11. The monitor device 11 is tilted by a predetermined angle (the angle and direction of the speaker 31-1 with respect to the normal of the display surface of the monitor device 11 is different and the tilt is the same (the absolute value is the same and the sign is different)). When viewed, the speaker 31-3 is provided in the monitor device 11 so that the propagation direction of the sound radiated from the speaker 31-3 is parallel to the normal line of the display surface of the monitor device 11.

  Further, when the monitor device 11 is viewed from above, the propagation direction of the sound radiated from the speaker 31-4 is a predetermined angle (speaker 31-3) counterclockwise with respect to the normal line of the display surface of the monitor device 11. When the monitor device 11 is viewed from the side, the propagation direction of the sound radiated from the speaker 31-4 is parallel to the normal line of the display surface of the monitor device 11. The speaker 31-4 is provided in the monitor device 11.

  That is, the sound from the speaker 31-3 and the speaker 31-4 is radiated diagonally forward from the vertical end on the right side when the monitor device 11 is viewed from the front.

  In addition, the angle which the monitor apparatus 11 and the speaker 31-1 thru | or the speaker 31-4 make can be made into arbitrary angles, and does not limit this invention.

  Hereinafter, the speakers 31-1 to 31-4 will be simply referred to as speakers 31 when it is not necessary to distinguish them individually.

  FIG. 7 is a diagram illustrating the structure of the speaker 31-1. The speaker 31-1 includes a speaker unit 51, a baffle plate 52, an upper lid 53, a lower lid 54, and an inner horizontal lid 56.

  The speaker unit 51 is a dynamic speaker unit and outputs sound.

  The method of the speaker unit 51 does not specify the present invention, and may be another method such as a piezoelectric type or a capacitor type, and the shape of the diaphragm is also a cone type, a dome type, or a ring type. Any of these may be used.

  A speaker unit 51 is fixed to the baffle plate 52. The baffle plate 52 is formed in a quadrangular shape using a material suitable for the speaker enclosure such as wood, resin, or metal such as MDF (Medium Density Fiberboard). One entire vertical end of the baffle plate 52 is in contact with the back surface of the display surface of the monitor device 11, and the other vertical end of the baffle plate 52 is parallel to the end portion of the display surface of the monitor device 11. The baffle plate 52 is disposed obliquely with respect to the monitor device 11 so as to be separated from each other.

  In other words, one end of the baffle plates 52 on both sides of the baffle plate 52 sandwiching the speaker unit 51 is in contact with the back surface of the display surface of the monitor device 11 and the other end is an edge of the display surface of the monitor device 11. The baffle plate 52 is disposed at a predetermined angle with respect to the display surface of the monitor device 11 so as to be away from the unit.

  The upper lid 53 and the lower lid 54 are formed in a quadrangular shape using the same material as the baffle plate 52 and are arranged so as to be orthogonal to the baffle plate 52 and the display surface.

  The upper lid 53 is in contact with the back surface of the display surface and the baffle plate 52 from above, and closes the space between the back surface of the display surface and the front side of the baffle plate 52, which is the front surface of the speaker unit 51. The lower lid 54 is in contact with the back surface of the display surface and the baffle plate 52 from below, and closes the space between the back surface of the display surface and the front side of the baffle plate 52 from below.

  Of the space between the back surface of the display surface and the front side of the baffle plate, which is the front surface of the speaker unit 51, the surface located in the direction of propagation of the sound radiated from the speaker unit 51 is open. An opening 55 is formed. That is, for example, the opening is surrounded by the vertical end of the display surface of the monitor device 11, the vertical end of the baffle plate 52 away from the display device, the end of the upper lid 53, and the end of the lower lid 54. 55 is formed.

  When arranged adjacent to the other monitor device 11, the opening 55 is formed so that the gap with the opening 55 of the other monitor device 11 becomes smaller. For example, the opening 55 is formed so as to coincide with a surface obtained by translating a straight line at a part of the end of the side surface of the monitor device 11 in a direction orthogonal to the display surface of the monitor device 11.

  The inner horizontal lid 56 is in contact with the ends of the upper lid 53 and the lower lid 54 opposite to the opening 55. That is, the space surrounded by the back side of the baffle plate 52, the upper lid 53, and the lower lid 54 is closed from the lateral direction by the inner lateral lid 56. Thus, the opening 57 orthogonal to the opening 55 is surrounded by the vertical end of the baffle plate 52, the end of the upper lid 53, the end of the lower lid 54, and the inner horizontal lid 56. It is formed.

  Further, as shown in FIG. 8, the opening 57 is closed with a cover 72 provided on the back surface of the monitor device 11 together with a substrate 71 built in the monitor device 11 and the like. In this way, transmission of sound radiated from the back surface of the speaker unit 51 can be blocked, and a volume that does not hinder the vibration of the diaphragm can be secured on the back surface of the speaker unit 51.

  Note that the speakers 31-2 to 31-4 are configured in the same manner as the speaker 31-1, and thus the description thereof is omitted.

  In addition, it has been described that the speakers 31-1 to 31-4 are configured such that the opening 55 is lateral to the monitor device 11, but the opening 55 is upward or downward with respect to the monitor device 11. As described above, the speakers 31-1 to 31-4 may be configured.

  A saran net or a punching metal may be provided in the opening 55 or the opening 57.

  Furthermore, in order not to disturb the movement of the diaphragm of the speaker unit 51, the cover 72 may be omitted and the opening 57 may be opened.

  The baffle plate 52, the upper lid 53, the lower lid 54, and the inner horizontal lid 56 may be formed so as to form a curved surface.

  With reference to FIG. 9 and FIG. 10, the audio | voice output of the several monitor apparatus 11 arranged so that it adjoins horizontally may be demonstrated.

  FIG. 9 is a diagram showing a monitor device 11-n and a monitor device 11- (n + 1) among the plurality of monitor devices 11 arranged side by side.

  Hereinafter, the speaker 31-1 and the speaker 31-3 of the monitor device 11-n are referred to as a speaker 31-1-n and a speaker 31-3-n, respectively, and the speaker 31-1 of the monitor device 11- (n + 1) and The speaker 31-3 is referred to as a speaker 31-1- (n + 1) and a speaker 31-3- (n + 1), respectively. The configuration of the speaker 31 is also identified by the same reference numeral.

  When the monitor device 11-n and the monitor device 11- (n + 1) are arranged so as to be horizontally adjacent to each other with a gap w, the speaker 31-3-n and the speaker 31-1- (n + 1) face each other. To be arranged. The propagation direction of the sound emitted from the speaker 31-3-n and the propagation direction of the sound emitted from the speaker 31-1- (n + 1) intersect.

  As shown in FIG. 10, the position of the opening 55-3-n and the position of the opening 55-1- (n + 1) coincide with each other with a gap w therebetween. For example, the gap w is about several mm.

  A space partitioned by a baffle plate 52-3-n, an upper lid 53-3-n, a lower lid 54-3-n, and a rear surface of the monitor device 11-n on the front surface of the speaker unit 51-3-n; Baffle plate 52-1- (n + 1), upper lid 53-1- (n + 1), lower lid 54-1- (n + 1), and rear surface of monitor device 11- (n + 1) on the front surface of 51-1- (n + 1) Are combined so that the space partitioned by the openings 55-3-n and the openings 55-1- (n + 1) are connected to each other.

  The volume of the gap w is a space formed by the space in front of the speaker unit 51-3-n and the space in front of the speaker unit 51-1- (n + 1) (the space indicated by ABCDEF in the figure). It is made sufficiently small compared to the volume.

  Since the space in front of the speaker unit 51-3-n and the speaker unit 51-1- (n + 1) is closed except for the gap w, the sound output from the speaker unit 51-3-n and the speaker The sound output from the unit 51-1- (n + 1) is radiated from the gap w.

  At this time, when only one of the speaker unit 51-3-n and the speaker unit 51-1- (n + 1) outputs sound, the other absorbs the vibration, and the speaker unit 51-3-n and the speaker If the unit 51-1- (n + 1) outputs a different sound, the sound will be canceled out, so that the speaker 31-3-n and the speaker 31-1- (n + 1) (speaker unit 51-3-n And the speaker unit 51-1- (n + 1)) output the same sound, that is, sound having the same phase and strength.

  When the phase of the sound output from the speaker unit 51-3-n and the phase of the sound output from the speaker unit 51-1- (n + 1) deviate in the range of 0 degrees to 180 degrees, the phase difference is large. The sound pressure tends to decrease.

  In this way, for example, when the diaphragm of the speaker unit 51-3-n moves forward, the diaphragm of the speaker unit 51-1- (n + 1) simultaneously moves forward, and the speaker unit 51- When the 3-n diaphragm moves rearward, the diaphragm of the speaker unit 51-1- (n + 1) moves rearward at the same time, so that the speaker unit 51-3-n and the speaker unit are entirely closed. The sound generated in the space in front of 51-1- (n + 1) is radiated from the gap w without being absorbed or canceled.

  When the same sound is output to the speaker 31-3-n and the speaker 31-1- (n + 1), as shown in FIG. 11, from the gap w between the monitor device 11-n and the monitor device 11- (n + 1). The sound is radiated in front of the monitor device 11-n and the monitor device 11- (n + 1).

  Further, when the same sound is output to the speaker 31-4-n and the speaker 31-2- (n + 1), similarly, the monitor device from the gap w between the monitor device 11-n and the monitor device 11- (n + 1) The sound is radiated in front of 11-n and the monitor device 11- (n + 1).

  FIG. 12 is a diagram illustrating an example of a configuration of a sound processing unit in the monitor device 11. The sound processing unit of the monitor device 11 includes a tuner 91, a selector 92, an inter-monitor connection interface 93, a control unit 94, an amplifier 95-1, an amplifier 95-2, and a light receiving unit 96.

  The tuner 91 receives a broadcast program and supplies the right channel audio signal and the left channel audio signal of the received program audio to the selector 92 and the inter-monitor connection interface 93.

  The selector 92 is supplied from the right channel audio signal or the left channel audio signal supplied from the other monitor device 11 via the inter-monitor connection interface 93 or the tuner 91 based on the control of the control unit 94. The audio signal of one channel is selected from the audio signals of the left channel, and the selected audio signal is supplied to the amplifier 95-1. Further, the selector 92 is supplied from the right channel audio signal or the left channel audio signal or the tuner 91 supplied from another monitor device 11 via the inter-monitor connection interface 93 based on the control of the control unit 94. One of the right channel audio signals thus selected is selected, and the selected audio signal is supplied to the amplifier 95-2.

  The inter-monitor connection interface 93 transmits the audio signal supplied from the tuner 91 to the other monitor device 11 and supplies the audio signal supplied from the other monitor device 11 to the selector 92. The inter-monitor connection interface 93 supplies an audio signal to another monitor device 11 according to a standard such as IEEE (Institute of Electrical and Electronic Engineers) 1394 or USB (Universal Serial Bus), or other An audio signal is acquired from the monitor device 11.

  The control unit 94 controls the selection of the audio signal of the selector 92 based on the command transmitted from the remote controller 97 and received by the light receiving unit 96.

  The amplifier 95-1 drives the speaker 31-1 and the speaker 31-2 based on the audio signal selected and supplied by the selector 92. The amplifier 95-2 drives the speaker 31-3 and the speaker 31-4 based on the audio signal selected and supplied by the selector 92.

  Note that the audio signal supplied together with the image signal from an external device via a connection terminal conforming to a predetermined standard is not limited to the audio signal from the tuner 91, and is replaced with the selector 92 or the monitor instead of the audio signal from the tuner 91. It may be supplied to the inter-connection interface 93.

  Moreover, you may make it supply or acquire the audio | voice signal of an analog signal between the other monitor apparatuses 11. FIG.

  Even if only the audio signal that causes the other monitor device 11 to output audio is transmitted between the monitor devices 11, the audio signals of the connected monitor devices 11 are transmitted in parallel. One audio signal may be selected from the audio signals.

  FIG. 13 is a diagram for explaining sound output from the monitor devices 11-1 to 11-3 arranged side by side.

  A case will be described in which the monitor devices 11-1 to 11-3 are arranged in order from the left and the sound of the monitor device 11-2 is output by the monitor devices 11-1 to 11-3.
