The present disclosure relates to a field of audio technology, and more particularly, to a sound box assembly, a display apparatus, and an audio output method.
At present, with the development of science and technology, a screen thickness of a display apparatus such as a television is getting thinner and lighter, such that a volume and a mounting position of a component configured to play sound in the display apparatus are restricted. In order to meet preferred criteria for the thickness and weight of the display apparatus, a loudspeaker arranged in the display apparatus may not have sufficient space for playing bass. The loudspeaker is arranged at various locations in a display apparatus, including a lower portion of the front side or the back side of the display apparatus. The loudspeaker may be facing downwards, rearwards or sideways.
According to a first aspect of the embodiments of the present disclosure, a sound box assembly for a display apparatus is provided. The sound box assembly includes: a housing defining a chamber therein, and a connecting part connected to the housing and configured to be connected with the display apparatus; and a loudspeaker arranged in the chamber of the housing, a sound-image center being disposed at a center position of the display apparatus when the loudspeaker playing sound. The loudspeaker includes: a squawker arranged at a middle portion of the housing; and a woofer and a tweeter. One of the woofer and the tweeter is arranged above the squawker, and the other one of the woofer and the tweeter is arranged below the squawker.
According to a second aspect of the embodiments of the present disclosure, a display apparatus is provided, and includes a screen and two sound box assemblies arranged on both sides of the display apparatus, respectively. The sound box assembly includes: a housing defining a chamber therein, and a connecting part connected to the housing and configured to be connected with the display apparatus; and a loudspeaker arranged in the chamber of the housing, a sound-image center being disposed at a center position of the display apparatus when the loudspeaker playing sound. The loudspeaker includes: a squawker arranged at a middle portion of the housing; and a woofer and a tweeter. One of the woofer and the tweeter is arranged above the squawker, and the other one of the woofer and the tweeter is arranged below the squawker.
According to a third aspect of the embodiments of the present disclosure, an audio output method for a display apparatus is provided. The display apparatus includes a screen and two sound box assemblies arranged on both sides of the screen, respectively. The audio output method includes: detecting an audio output state of the sound box assembly; driving the sound box assembly to move from a first position to a second position when the sound box assembly is in the audio output state; and driving the sound box assembly to move from the second position to the first position when the sound box assembly exits the audio output state. The first position is disposed on a back side of the screen, and the second position is disposed on a left or right side of the screen.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure, as claimed.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the disclosure and, together with the description, serve to explain the principles of the disclosure.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the disclosure as recited in the appended claims.
In the related art, a loudspeaker is arranged at a lower portion of a display apparatus, and faces downwards, or arranged on a back side of the display apparatus, and faces rearwards or sideways. In the above ways, a sound needs to reflected and diffused so as to be heard by a viewer, such that the sound quality is seriously damaged, thereby resulting in that the sound and a sound image received by a user watching the display apparatus are separated from a position of a screen. The sound image, also known as a virtual sound source or a sensory sound source, refers to a position of a sound source that is virtualized based on the sound heard by the user after he/she hears the sound. When using the display apparatus in the above related art, the user watches the image displayed by the screen and also listens to the sound output from the loudspeaker of the display apparatus. However, the position of the sound source virtualized based on the sound is not at a position of the image, thus resulting in a problem of separation of the sound and the image, which causes a poor user experience.
If the sound quality is improved through an external sound box, the cost will be increased and an additional space is required.
In order to solve the above technical problems, the present disclosure provides a sound box assembly 10, which may be applied to a display apparatus 100. The display apparatus 100 may be a television and includes a screen 20. As illustrated in
As illustrated in
In this embodiment, the connecting part 12 may be directly connected with the housing 11 or fixedly connected with the housing 11 through a connector. Also, the connecting part 12 is further connected with the display apparatus 100, such that the sound box assembly 10 is connected with the display apparatus 100. The display apparatus 100 may include a moving part capable of moving to drive the connecting part 12 to move, so as to enable the sound box assembly 10 to move, which will be described in related embodiments later.
According to the arrangement of the sound box assembly 10 described above, the chamber formed in the housing 11 defines a relatively large space, so as to improve the sound quality, especially the bass generated by the woofer 131, which may produce the bass effect with high quality through the chamber of the large space.
Moreover, in this embodiment, the numbers of the woofers 131, the squawkers 132 and tweeters 133 may be one or more, respectively. In the drawings of the present disclosure, two woofers 131, one squawker 132 and one tweeter 133 are illustrated as an example, but the present disclosure is not limited to this. The squawker 132 is disposed at the middle portion of the housing 11 and may be arranged adjacent to a middle position in a vertical direction of the display apparatus 100. The woofer 131 may be disposed above the squawker 132 and the tweeter 133 may be disposed below the squawker 132. Or, the woofer 131 may be disposed below the squawker 132 and the tweeter 133 may be disposed above the squawker 132. Through the above arrangements, the sound-image center may be disposed at a middle height when the sound is being played, and the sound image may be disposed in a central position of the display apparatus 100 through left and right sound box assemblies 10, such that when watching an image of the display apparatus 100, the position of the virtual sound source that is heard is the same with the position of the image, which may bring a better experience to the user.

In an embodiment, as illustrated in
In this embodiment, the bracket 15 may be arranged in the housing 11, and the mounting hole 151 is formed in the bracket 15 for receiving the loudspeaker 13. The number, position and opening size of the mounting hole 151 may be determined according to the numbers, positions and corresponding structures of the woofer 131, the squawker 132 and the tweeter 133. The loudspeaker 13 is mounted in the mounting hole 151, a front surface of the loudspeaker 13 faces towards a front side, i.e. a side of the screen 20 of the display apparatus 100, which displays the image, and a back surface of the loudspeaker 13 may be connected with a control circuit, a power supply circuit, or the like via the back side of the bracket 15 through a wiring 134.
The sound guide hole 152 is also formed in the bracket 15, and the sound guide groove 141 is arranged on the back side of the bracket 15 and having the position to that of the sound guide hole 152. The sound guide groove 141 is connected with the back side of the bracket 15, and has an opening facing towards the woofer 131 in its end, such that the vibration of the woofer 131, the squawker 132 and the tweeter 133 on the back side of the bracket 15 can be collected, and then the sound can be transmitted to the front side through the sound guide hole 152 and be played.
In some embodiments, a connecting plate 153 may be connected to the bracket 15, and configured to be connected with the connecting part 12. Since the loudspeaker 13 is mounted on the bracket 15, the bracket 15 has a relatively large weight. The connecting part 12 is directly connected to the connecting plate 153, which may reduce the force-supporting components, and the connecting part 12 directly achieves the support for the sound box assembly 10. In some embodiments, as illustrated in
In an embodiment, as illustrated in
The left-right direction generally refers to a linear direction of the left and right sides of the display apparatus 100 when the display apparatus 100 is in use and the screen 20 faces towards the front side. If the display apparatus 100 is arranged vertically, that is, when the screen 20 is arranged perpendicular to a horizontal plane, the left-right direction is a horizontal direction. In this embodiment, the sound box assembly 10 may be configured to move relative to the screen 20, and the display apparatus 100 may include a moving part configured to move, a driving part configured to drive the moving part to move, etc. The sound box assembly 10 may be connected to the moving part through the connecting part 12, and the display apparatus 100 may drive the moving part to move through the driving part, so as to drive the sound box assembly 10 to move between the first position and the second position. The first position may be located on the back side of the screen and adjacent to left and right ends of the screen 20. When the sound box assembly 10 is in the first position, the user cannot observe the sound box assembly 10 from the front side of the display apparatus 100. The second position may be located on a left or right side of the screen 20. In some embodiments, the second position corresponds to the first position adjacent to the left end of the screen 20, and extends leftwards beyond the back side of the screen 20. When being in the second position, the sound box assembly 10 extends out of a boundary of the left side of the screen 20, so as to expose the loudspeaker 13 completely. Thus, the user can observe the sound box assembly 10 from the front side of the display apparatus 100, and the sound played by the sound box assembly 10 can also be transmitted to the user without being blocked and reflected. In some other embodiments, the second position corresponds to the first position adjacent to the right end of the screen 20, that is, there is also a second position on the right side of the screen 20, the principle of which is the same with that of the second position on the left side, and thus will not be repeated herein. In an audio output state, that is, when the sound needs to be played, for example, when the display apparatus 100 is turned on and ready to play a program or in the state of playing a program, the sound box assembly 10 may be moved to the second position so as to be exposed from the left or right side of the screen 20 of the display apparatus 100, thus playing the sound to the front side, which avoids sound quality from being damaged. When the audio output state ends, that is, when the sound does not need to be played, for example, the display apparatus 100 is turned off or in a standby state, the sound box assembly 10 may be moved to the first position, that is, the sound box assembly 10 is located on the back side of the screen 20, such that the appearance of the display apparatus 100 is simple and aesthetic. The sound box assembly 10 may be received in the housing of the display apparatus 100. The above movement may be a linear movement or a flipping movement, etc.
In addition, the distance sensor 17 may be arranged on a side of the housing 11, i.e. the side away from the screen 20, for detecting whether there is an object on an outer side of the housing 11 and a distance to the object. As illustrated in
In an embodiment, the distance sensor 17 may include a first distance sensor 171 disposed at the lower portion of the housing 11. Generally, the object is placed on the ground or table, so the object generally extends from bottom to top. In this embodiment, the first distance sensor 171 is disposed at the lower portion of the housing 11, and faces outwards, thereby better detecting the object and avoiding the failure of detecting the object because of being arranged at a high position.
In an embodiment, the distance sensor 17 may further include one or more second distance sensors 172 disposed above the first distance sensor 171. In some embodiments, the object placed on the side of the display apparatus 100 may have an irregular shape, such as some vases with a narrow bottom and a wide top, or objects extending from the side, such that the first distance sensor 171 arranged below may be unable to detect the object in the middle or above position. In this embodiment, in order to better detect the object and avoid the collision, one or more second distance sensors arranged above the first distance sensor 171 may be provided. For example, as illustrated in

In an embodiment, as illustrated in
Based on the same conception, the present disclosure also provides a display apparatus 100. The display apparatus 100 includes two sound box assemblies 10 according to the above embodiments, the two sound box assemblies 10 are arranged on both sides of the display apparatus 100, respectively, and upper and lower ends of the sound box assembly 10 are flush with upper and lower ends of the display apparatus 100, respectively, so as to increase an internal space of the sound box assembly 10, thereby improving the quality of the played sound. Especially for a bass, the improvement of the space of the sound box may improve the listening experience and achieve a stunning bass effect. Moreover, the sound box assembly 10 is arranged on the side of the display apparatus 100, so as to directly play the sound to the front side of the display apparatus 100 when playing the sound, reduce an excessive interference of the sound reflected by walls or other objects on the direct sound of the sound box, obtain a good sense of positioning and a wide and deep sound field, and enable the user to hear the maximum, the most direct and the clearest details.
Based on the same conception, the present disclosure further provides an audio output method 30, which may be applied to the display apparatus 100 of the above embodiments, such as a television, etc. As illustrated in
At step S31, an audio output state of the sound box assembly 10 is detected.
If the sound box assembly 10 is in the audio output state, step S32 is executed. In step S32, the sound box assembly 10 is driven to move from the first position to the second position.
If the sound box assembly 10 exits the audio output state, step S33 is executed. In step S33, the sound box assembly 10 is driven to move from the second position to the first position.
The first position is disposed on the back side of the screen 20 of the display apparatus 100, and the second position is disposed on the left or right side of the screen 20.
The audio output method 30 according to the embodiments of the present disclosure may obtain the audio output state of the sound box assembly 10 according to a current state of the display apparatus 100. For example, when the display apparatus 100 is turned on and music needs to be played, the sound box assembly 10 is in the audio output state, ready to play or playing sound, and thus the sound box assembly 10 is driven to move from the first position to the second position through the moving part and the driving part of the display apparatus 1000, such that the sound box assembly 10 is exposed, and the loudspeaker may output the sound forwards, thereby ensuring the sound quality. If there is no need to play the sound at present, for example, when the display apparatus 100 is turned off or in a standby state, the sound box assembly 10 may be moved to the first position, i.e. on the back side of the screen 20, such that the appearance of the display apparatus 100 is simple and aesthetic. The sound box assembly 10 may be received in the housing of the display apparatus 100, and the above movement may be a linear movement or a flipping movement, etc.
