Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a display device. Background Art

[0002] As the TV frame becomes narrower and thinner, the internal space is getting smaller and smaller. Therefore, the conventional way of far-field sound pickup design is to integrate the buttons, indicator lights, remote control lights and remote sound pickup functions of the TV set, and hang them in the middle of the bottom of the front shell of the whole machine to meet the requirements of the existing narrow and thin frame design and facilitate voice interaction.

[0003] Driven by the Internet+ and intelligence, far-field sound pickup applications have gradually become standard for TV products. By activating the far-field sound pickup function through the wake-up word, intelligent voice control is simpler and more convenient, achieving direct control and interaction, and bringing a better user experience. The implementation of the far-field voice function of TV products is divided into two parts: the far-field voice module on the hardware and the artificial intelligence technology on the software. The front end uses microphone array hardware to perform voice enhancement through sound source positioning and adaptive beamforming, complete far-field sound pickup, and solve the effects of noise, reverberation, echo, etc.

[0004] However, based on the indoor sound propagation characteristics of geometric acoustics: the sound signal received by the receiving end of the pickup module can be regarded as a mixture of different multipath components. Compared with the sound source signal, the energy and phase of these signal components have changed (due to propagation through different paths, energy attenuation caused by absorption by the reflection interface and the atmosphere, and time delay caused by different reflection path lengths), that is, the multipath effect will bring a series of problems such as delay asynchrony, signal attenuation, polarization change, link instability, etc. In addition, the main energy source of the received signal is the reflected and scattered signals, and the acoustic signal components from the reflection account for a large proportion.

DETAILED DESCRIPTION

[0048] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more comprehensive and complete and will fully convey the concept of the example embodiments to those skilled in the art.

[0050] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0051] In the voice interaction process of the display device, based on the indoor sound propagation characteristics of geometric acoustics: the sound signal received by the receiving end of the pickup module can be regarded as a mixture of different multipath components. Compared with the sound source signal, the energy and phase of these signal components have changed (due to propagation through different paths, energy attenuation caused by absorption by the reflection interface and the atmosphere, and time delay caused by different reflection path lengths), that is, the multipath effect will bring a series of problems such as time delay asynchronization, signal attenuation, polarization change, link instability, etc.; in addition, the main energy source of the received signal is the reflected and scattered signals, and the acoustic signal components from the reflection account for a large proportion.

[0052] Based on the theory of geometric acoustics, due to the strong multipath propagation effect in the room, most of the technical solutions currently adopted in the industry are to improve the sound pickup effect by adjusting the microphone array of the far-field pickup itself or the structural design of the front shell where the far-field pickup is located. Although this can ensure the sound pickup performance, such solutions only improve from the target node and cannot improve the impact of the sound blocking and reflection of the components near the far-field pickup on the sound pickup. The structure of the television is complex, the wavelength of the sound signal is short, and the penetration ability is weak. In the process of propagation from the voice control to the microphone sound pickup, it is difficult to avoid the interference of the microphone sound pickup due to the blocking and reflection of the structural components, resulting in the weakening of the sound pickup performance. The present application provides a display device to solve the above technical problems.

The width direction of the display device is the left-right direction.

Fig.17 It is a structural schematic diagram of another specific embodiment of the practical base.

[0093] See also Figures 8 to 17 The base 30 is fixed to the back of the display body 10 to support the display body 10. The base 30 includes a bottom plate 310 for supporting on a support surface, and a support plate 320 extending upward from the bottom plate 310; the upper end of the support plate 320 is fixedly connected to the back of the housing 110, and the lower end of the support plate 320 extends downward beyond the housing 110 and the pickup module 20 to support the display body 10 on the support surface (desktop, bottom surface).

[0094] In this embodiment, one base 30 is provided, and the single base 30 is located in the middle of the display body 10 in the left-right direction to ensure that the display body 10 is stable in the left-right direction after being supported on the base 30. The vertical projection of the display body 10 is located on the bottom plate 310 in the front-back direction, so that the display body 10 is stably arranged in the front-back direction.

[0095] In this embodiment, the base 30 and the sound pickup module 20 are both located in the middle of the display body 10 in the left-right direction, so that the rear projection of the sound pickup module 20 falls on the support plate 320. The base 30 is provided in one piece, and the base 30 is fixed in the middle of the housing 110 in the left-right direction; the center of the sound pickup hole 130 in the left-right direction is located on the center line of the housing 110 in the left-right direction.

When the sound waves transmitted from the front to the back to the two sound pickup holes 130 are transmitted backward, since the length of the third surface 323 in the left-right direction is less than the distance between the two corresponding sound pickup holes 130, the sound waves transmitted backward can be effectively transmitted to the first surface 321 or the second surface 322. The first surface 321 and the second surface 322 are arranged to be tilted relative to the third surface 323, so that after the sound waves are reflected by the first surface 321 or the second surface 322, the sound waves can be effectively avoided from being reflected to the corresponding sound pickup holes 130, effectively reducing the interference of the base 30 on the sound pickup module 20, and improving the accuracy of voice interaction.

[0107] tanα=d / 51>36 / 51

[0108] α>35.22°

[0109] In this embodiment, the angle α is greater than 35° or is in the range of 24° to 35°, so as to effectively reflect the sound waves and effectively reduce the interference of the emitted sound waves on the sound pickup module 20 .
