Fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present invention.

Referring to fig. 1, the display device provided in the embodiment of the present invention mainly includes a display main body 100 and a sound bar 200, and the sound bar 200 is in signal connection with the display device 100, so that the sound bar 200 is applied to a multi-channel sound system, and can ensure a better bass effect, and simultaneously meet the requirements of small size and light weight of the sound bar 200, so that the sound bar 200 can be more freely placed, and the practicability is strong.

The display main body 100 has a display screen for displaying images, and a sound system is built in the display main body, and is an input/output playing device for video and audio. Therefore, the display main body 100 is not limited to a television such as a liquid crystal television or a plasma television, and includes other audio input devices having a display screen such as a computer. The display main body 100 includes a control main board, and a power interface, an external device interface, and the like electrically connected to the control main board. The external device interface is used for connecting the external equipment, so that the media asset data is sent to the external equipment.

The sound bar 200 is horizontally disposed and located on the bottom of the display main body 100, and of course, the sound bar 200 may be disposed at the front side of the display main body 100 at intervals, or may be hung on a wall for playing music.

Soundbar 200 acts as an external device with audio output capabilities. The sound bar 200 may be connected to an external device interface of the display main body 100 through a cable by a specific interface specification, such as HDMI, USB, or the like. For example, the sound bar 200 may be connected to the display main body 100 through a USB interface. When the display main body 100 needs to output audio, the audio data may be transmitted to the sound bar 200 through the USB interface, and the sound bar 200 converts the audio data into a sound signal to implement audio output.

It can be understood that the sound bar 200 may also be connected to the display main body 100 via a built-in bluetooth module or WIFI module through a wireless signal.

In some embodiments, sound bar 200 may further perform sound quality processing on the audio transmitted by display body 100 to play the audio data according to a specific output mode, so as to obtain a corresponding sound quality effect. Therefore, the user can realize the control of the data processing function through interactive action, namely, the setting of the output mode is realized. For example, settings that sound bar 200 is capable of supporting include sound modes, surround switches, treble adjustments, bass adjustments, display screen brightness adjustments, factory reset settings, and the like.

In some embodiments, the display device further includes an external subwoofer 300. Subwoofer 300 is disposed on one side of sound bar 200 and is in signal connection with sound bar 200, such that sound bar 200 and subwoofer 300 cooperate to form an external 2.1 channel system.

The 2.1 channel is the common 2.0 channel (two loudspeakers form the left and right channels) added with one subwoofer to form a third channel except the left and right channels. Since the current sound box tends to be light, bass reduction can be affected while the volume of the sound box is reduced. Therefore, the bass can compensate the bass loss caused by the reduction of the volume of the sound box and enhance the bass.

It is understood that in some other embodiments, subwoofer 300 may also be built into soundbar 200 to increase the integration and compactness of the display device. The volume is minimized, and simultaneously, the sound quality is improved to the maximum extent.

In other embodiments, the sound bar 200 can be used in combination with other sound devices to form 5.1 channels and 7.1 channels according to the diversified requirements of the user, so as to realize richer surround sound.

At present, in a bar-type sound box, a structure that an upper shell and a lower shell are mutually assembled is generally adopted, sealing grooves are respectively arranged at the splicing positions of the upper shell and the lower shell, and then sealing rings are arranged in the sealing grooves to form sealing fit. However, the sealing ring is difficult to align with the sealing groove, the assembly difficulty is increased, and the sealing ring and the sealing groove are easy to generate a phenomenon of local misalignment, so that the sealing effect between the upper shell and the lower shell is influenced.

In the sound bar 200 provided by the embodiment of the present invention, the structure of the sound bar 200 in the related art is optimized, so as to reduce the assembly difficulty of the sound bar 200 and ensure the overall sealing and damping effects of the sound box.

The sealing and damping of the enclosure has a large effect on the sound quality of the enclosure, the most important of which is enclosure resonance. The tightness inside the sound cavity influences the occurrence and resonance of the loudspeaker, and further influences the sound quality of the sound produced by the sound box. Between the structure of assembling of epitheca and inferior valve, if do not have the sealing washer to seal the shock attenuation, then take place resonance easily between epitheca and inferior valve for the sound tone quality that the audio amplifier sent is relatively poor. And because the loudspeaker is mainly characterized in that the basin frame of the loudspeaker is fastened on the front panel of the sound box shell through the screws, namely the basin frame is directly contacted with the front panel, the vibration generated when the loudspeaker works can be directly transmitted to the front panel of the sound box shell through supporting structures such as the basin frame and the like, and then the sound box shell resonates. Also some audio amplifier pass through the support and fix the speaker on other panels, the speaker during operation can directly transmit the vibration to the panel of fixing with it like this for the audio amplifier casing takes place resonance, makes the sound tone quality that the audio amplifier sent relatively poor. Sound wave pressure accumulated inside the sound box shell can directly excite the sound box shell to vibrate, and the sound quality of sound emitted by the sound box is poor.
