The utility model provides a terminal system, please refer to fig. 1 and 4, the terminal system includes a display device 30 and a sound system, the display device 30 has a display surface, a sound receiving position is located at the front side of the display surface, the sound system includes two first sound devices 10 and a second sound device 20, the two first sound devices 10 are respectively arranged at the left and right sides of the display surface, the second sound device 20 is arranged at the top of the display surface, in the vertical direction, the height of the first sound device 10 is lower than or equal to the height of the sound receiving position, and the height of the second sound device 20 is greater than or equal to the height of the sound receiving position.

In this embodiment, the sound system can be applied to various types of display devices, for example, a PC computer, a television, or a projector. Specifically, the first audio 10 may be disposed on the left side or the right side of a display surface, where the display surface may be a display screen of a PC computer, a projection screen or a projection wall of a television or a projector, or the like; the second speaker 20 is disposed on top of the display surface. The positions of the first audio 10 and the second audio 20 need to be adjusted before the audio system is set up.

When a user uses the microphone, the user's ear is used as a sound receiving position, and the sound receiving position may also refer to a sound receiving device such as a microphone when recording or making other audio. Taking the example of the audio system being used by the user in a PC computer, the user sits in front of the display device 30 and defines the position of the user's ear as the sound reception position.

Specifically, the first sound box 10 is disposed below the sound pickup position, that is, the height of the first sound box 10 is lower than the height of the sound pickup position. For example, the first speakers 10 may be disposed on both sides of the display device 30, the number of the first speakers 10 may be two, one of the two first speakers 10 may be a left channel speaker, and the other may be a right channel speaker, so that a user can recognize a sound originating from the left side or a sound originating from the right side through the first speakers 10 when using the display device. The second audio 20 is located between the two first audio 10. Meanwhile, the second sound box 20 is arranged at a height greater than the sound receiving position, for example, the second sound box 20 can be arranged on the top of the display surface, and the second sound box 20 is fixed through an external connecting piece, so that a user can recognize the sound from the top through the second sound box 20 at a higher position when using the loudspeaker.

It can be understood that, in one sound source information, a plurality of audio frequencies of different channels are included, and the audio frequencies of different channels in the sound source information are played through different sound equipment. For example, only the audio in the top sound source region is sent to the second sound box 20 for playing, so as to ensure that the user can only listen to the sound at the top of the head through the second sound box 20. And also, left channel information and right channel information are divided and played through the left channel and the right channel of the first audio 10, respectively, so as to simulate the effect of ambient sounds on the left and right sides of the user.

Specifically, after the sound source information is acquired, the sound source information can be analyzed in a software processing mode, and the audios of different sound channels in the sound source information are respectively played through different sound boxes. Therefore, the simulation effect of the environmental sound is further improved in the using process of the user. For example, only the audio in the top sound source region is sent to the second sound device 20 for playing, and the second sound device 20 at the top of the display surface sends out a sound signal with a transverse width and higher than the sound receiving position forwards or upwards. Thereby ensuring that the user can only hear the overhead sound through the second stereo 20. In addition, the audio of the left and right sound source regions is played through the first stereo 10 on the left and right sides, respectively, and is matched with the second stereo 20, thereby presenting an immersive sound field restoration effect with azimuth feeling in both the vertical direction and the horizontal direction. The signal is compensated by processing of an electric filtering circuit or a digital filtering circuit, so that the audio quality is further improved, and the effect of environmental sounds positioned at the left side and the right side of a user is simulated.

In addition to the above manner, the compatibility of the optimization method of the sound system of the present invention can be further improved by distinguishing different frequencies, sending the sound source of the high frequency band to the second sound box 20 for playing, sending the sound source of the low and middle frequency bands to the first sound box 10 for playing, and the like, which can be set by a user according to the requirement.

According to the technical scheme, the first sounder 10 is located on the left side and the right side of the display surface, the second sounder 20 is arranged on the top of the display surface and is higher than the sound receiving position, and therefore through mutual matching of the first sounder 10 and the second sounder 20, an immersive sound field restoration effect with azimuth feeling in the vertical direction and the horizontal direction is presented.

Further, referring to fig. 2, the first sound box 10 includes a first housing 11, a front sound unit and a side sound unit, the front sound unit is disposed on a housing wall of the first housing 11 facing the sound receiving position, the side sound unit is disposed on a housing wall of the first housing 11 adjacent to the front sound unit, and a sound emitting direction of the side sound unit is perpendicular to a sound emitting direction of the front sound unit.

Specifically, the front sound emitting unit may be the intermediate frequency unit 14 and the high frequency unit 13, the side sound emitting unit may be the low frequency unit 12, the intermediate frequency unit 14 and the high frequency unit 13 are vertically disposed on a wall of the first housing on a side facing the sound receiving position, the low frequency unit 12 is disposed on a wall of the first housing 11 on a side adjacent to the front sound emitting unit, and a sound emitting direction of the intermediate frequency unit 14 and the high frequency unit 13 is perpendicular to a sound emitting direction of the low frequency unit 12.

In the present embodiment, since the sound in the mid-to-high band has a clear directivity, when the first audio device 10 is installed, the sound emission directions of the high frequency unit 13 and the intermediate frequency unit 14 are set on the side of the first casing 11 facing the user, that is, the display surface side of the display device 30, so that the sound attenuation in the mid-to-high band is minimized. The low frequency unit 12 is disposed at a side of the first housing 11, that is, the sound emitting direction of the low frequency unit 12 is perpendicular to the sound emitting direction of the high frequency unit 13. The arrangement at the side of the first housing 11 does not attenuate low frequencies.

Further, the number of the low frequency units 12 of each first sound box 10 is two, and the two low frequency units 12 are disposed on the first casing 11 in a reverse manner. Therefore, the two low-frequency units 12 are arranged back to back, when the same low-frequency signal is played, the vibration directions are opposite, and the vibration of the first shell 11 caused by inertia is just counteracted mutually, so that the audio effect is further improved. Meanwhile, as the two units equivalently increase the vibration area, more low-frequency energy can be provided.

Alternatively, the front sound generating unit may have only one intermediate frequency unit 14 or only one high frequency unit 13, the side sound generating unit may also be only a passive sound generating unit, and the first sound box 10 in the present application may have various design forms.

Further, referring to fig. 3, the second sound box 20 includes a second casing 21, a second sound unit 23 and a bracket 22, the second sound unit 23 is installed on the second casing 21, and the second casing 21 is connected to the display device 30 through the bracket 22. Since the display device 30 has different heights, there is a certain height difference between the second sound box 20 and the sound pickup position when the second sound box 20 is assembled. Therefore, when the second sound device 20 is assembled, the height difference between the second sound device 20 and the sound receiving position can be obtained through measurement, so that the sound emitting direction, the sound emitting angle and the like of the second sound device 20 can be adjusted according to the height difference. Therefore, by adjusting the sound emitting direction and the sound emitting angle of the second sound box 20, the user can obtain better use experience, and a more realistic environment sound effect is achieved.

In the present embodiment, the second casing 21 is disposed in an elongated shape, and at least one second sound unit 23 is disposed at two ends of the second casing 21. Therefore, the second audio 20 can also play in the left and right channels, so that the user experience is further improved, and the user can more clearly distinguish whether the sound is located at the left side of the top of the head, the right side of the top of the head, or the like.

Specifically, the sound output direction and the sound output angle of the second audio 20 are adjusted by adjusting the height, the installation angle, and the like of the stand 22 or the like provided between the second audio 20 and the display device 30. Or the bracket can also adopt a rotatable mounting buckle and the like, so as to drive the second sound box 20 to rotate; in addition, the installation height of the second sound box 20 can be adjusted by additionally arranging an expansion bracket, so that the compatibility of the optimization method of the sound system is further improved, and the user experience is improved.

Further, the second sound emitting unit 23 is disposed on a housing wall of the second housing 21 on a side away from the display device 30, and a sound emitting direction of the second sound emitting unit 23 faces the sound receiving position or an area above the sound receiving position. The adjustment can be made by determining whether the height of the second sound box 20 is greater than the sound receiving position. When the position of the second sound box 20 is higher than the sound pickup position, the sound emitting surface of the second sound unit 23 may be inclined more toward the sound pickup position, or the sound emitting surface of the second sound unit 23 may be arranged horizontally. The direct sound is more, and the time of the first sound device 10 and the second sound device 20 reaching the ear part of the sound receiving position is consistent.

When the height of the second sound box 20 is equal to or close to the height of the sound receiving position, the sound emitting direction of the second sound emitting unit 23 faces the area above the sound receiving position, and at this time, the sound emitting angle of the second sound emitting unit 23 is 15-20 degrees, wherein the sound emitting angle is an included angle between the sound emitting direction of the second sound emitting unit 23 and the vertical direction. Since the first stereo 10 is located below the sound pickup position, it is slow to reach the sound pickup position. When the height of the second sound box 20 is close to the sound pickup position, the sound emission direction of the second sound box 20 is inclined toward the top of the sound pickup position or toward the ceiling, and the sound of the second sound box 20 is reflected by the ceiling and reaches the sound pickup position. Thereby ensuring that the first sound box 10 and the second sound box 20 arrive at the sound receiving position at the same time. In addition, in order to meet the angle requirement of Dolby on the Atmos up-training microphone, the sound-emitting angle can be set to be 15-20 degrees, so that the audio quality is further improved.

Note that the sound emitting angle of the second sound unit 20 may be adjusted according to the height of the ceiling, and when the ceiling is low, the sound emitting direction of the second sound unit 20 may be set to the top. When the ceiling is high, the sound intensity is weakened after reflection, and the sound receiving effect of the second sound box 20 can be set in the horizontal direction or toward the sound receiving position.

Further, in this embodiment, the second sound box 20 may further include at least two third sound units 24, where the at least two third sound units 24 are respectively disposed on two end regions of the second casing 21 and on a side casing wall of the second casing 21 facing the sound receiving position, and the third sound units 24 and the second sound units 23 cooperate to generate sound, and the second sound box 20 is wider in rainy days and cooperates with the first sound box 10 to obtain a restoring effect of a more immersive sound field in vertical and horizontal directions.

Further, in this embodiment, the sound system further includes a microphone disposed on the first sound device 10 and/or the second sound device 20, and a controller electrically connected to the microphone and the first sound device 10 and the second sound device 20, where the microphone is configured to receive sound signals emitted by the first sound device 10 and the second sound device 20 and send the sound signals to the controller, and the controller is configured to adjust the volume of each sound frequency segment of the first sound device 10 and/or the second sound device 20 according to the sound signals. The microphone receives sound signals reflected by objects such as walls, so that the emitted audio frequency is adjusted and compensated in real time, when the sound emitted by the first sound box 10 and/or the second sound box 20 reaches the ears after being reflected by a room, the frequency response is relatively smooth, and the influence of the room reflection on certain frequency bands is reduced. Thereby further improving the audio quality of the optimization method of the sound system of the utility model.

Further, sound system still includes the light module, and the light module setting is on second stereo set 20, and the light module is connected with the controller electricity, and the controller still is used for adjusting the colour and the luminance of light module. In this embodiment, the controller can be additionally provided with a function button, and a user can switch the lighting mode of the light module by pressing one button. Light is supplemented through the light module to meet the lighting requirements of users in use; furthermore, it can also be used as an atmosphere lamp.
