Description

Technical Field

[0001] The present invention relates to the field of speaker technology, and in particular to a 5G smart speaker provided with an arc-shaped air duct. Background Art

[0002] A speaker is a device that can convert audio signals into sound. In layman's terms, it means that the speaker mainframe or subwoofer has a built-in power amplifier, which amplifies the audio signal and then plays it back by the speaker itself, making the sound louder. The speaker is the terminal of the entire sound system, and its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is an extremely important component of the sound system, responsible for converting electrical signals into sound signals for direct human hearing.

[0003] 5G Mobile Networks Like earlier 2G, 3G and 4G mobile networks, 5G networks are digital cellular networks in which the service area covered by the provider is divided into many small geographic areas called cells. Analog signals representing sound and images are digitized in the phone, converted by an analog-to-digital converter and transmitted as a bit stream. All 5G wireless devices in a cell communicate via radio waves with a local antenna array and low-powered automatic transceivers (transmitters and receivers) in the cell. The transceivers allocate channels from a common frequency pool, which can be reused in geographically separated cells. The local antennas are connected to the telephone network and the Internet via high-bandwidth fiber optic or wireless backhaul connections. As with existing mobile phones, when users traverse from one cell to another, their mobile devices will automatically "switch" to the antenna in the new cell.

[0004] With the advent of the 5G era, 5G has also brought many applications and changes to sound transmission. High sound quality and low latency are the significant features of sound transmission under the blessing of 5G. In the previous generation of 4G network environment, people have become accustomed to listening to music and watching audio programs online at any time. Sometimes it is live broadcast, but it is basically based on sound data transmission based on a large compression of sound quality. When the network transmission rate reaches about 10Gbps, high-definition sound quality can also be quickly transmitted through the network to ensure real-time sharing. On the other hand, the low latency characteristics of 5G networks have also brought new applications to bands. Band rehearsal can be said to be a very common scene in real life, but if the musicians of the band are not in the same city, they may be all over the country or even all over the world. If you have to find a place first every time you rehearse, and then everyone goes there to rehearse, it is obviously a time-consuming and laborious task, and it is often not very realistic. Fortunately, the 5G era is here, and people can make online rehearsals a reality. Just imagine, with the support of 5G's low latency, when the lead guitarist only needs to give a beautiful solo at home, the lead singer who is far away in another place only needs to quickly follow that beautiful solo at home and accurately cut into his voice, so that the entire online rehearsal can be completed efficiently and with high quality. This is a very convenient thing.

[0005] However, at present, there are 5G smart speakers that can be used for online rehearsals. They are usually smaller in size and have better sound quality, making them suitable for indoor use. However, there is still some gap compared to the huge audio system. Although the size meets people's needs, the sound quality is still a bit lacking. For the band's online rehearsal, it is still difficult to meet people's indoor sound quality requirements. Summary of the invention

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application.

The bass resonance auxiliary sound cavity can resonate to enhance the bass output intensity of the bass component and improve the sound quality of the bass component. When the sound wave of the bass component contains a signal in the resonance frequency band, it causes the resonance of the air in the resonance cavity.

Among them, the arc-shaped air duct includes any air duct designed in a non-linear shape. The shape that meets the flow velocity simulation requirements is a qualified design, which is significantly different from the conventional linearity. The biggest feature of this structural optimization of the conventional structure is: lower wind shear noise and better low-frequency extension characteristics. Figure 4 The structural diagrams of three types of curved air ducts are shown respectively. Under the same conditions, the flow rate of the curved air duct will be significantly reduced compared to that of the conventional air duct.

[0026] like Figure 1-3 As shown, the tweeter component 3 includes an outermost magnetic circuit device 31 and an innermost support bracket 32, the magnetic circuit device 31 and the support bracket 32 ​​are respectively located at the two ends of the tweeter component 3, the magnetic circuit device 31 is arranged close to the inner side of the 5G smart speaker housing 1, the support bracket 32 ​​is close to the inner center of the 5G smart speaker, and a tweeter resonance auxiliary sound cavity 4 is arranged between the support bracket 32 ​​and the magnetic circuit device 31. In this embodiment, the tweeter resonance auxiliary sound cavity can resonate to enhance the treble output intensity of the tweeter component and improve the sound quality of the tweeter component. Compared with the traditional speaker magnetic circuit device at the innermost side and the support bracket at the outermost side, the area enclosed by the lower bracket, the elastic wave and the drum paper inside the tweeter component can be used to increase the sound output area of ​​the tweeter component, greatly improve the sound quality of the tweeter component, and realize that the small-volume 5G smart speaker can achieve the same sound quality effect as a large sound system.

[0027] like Figure 3As shown, the magnetic circuit device 31 includes a magnet 311 and a washer 312, the magnet 311 and the washer 312 are fixedly connected, the tweeter component 3 is also provided with a voice coil 33, the voice coil 33 is located between the support bracket 32 ​​and the magnet 311, the voice coil 33 is fixedly connected to the magnet 311, the tweeter component 3 is also provided with a spring 34, the spring 34 is located between the support bracket 32 ​​and the voice coil 33, the two ends of the spring 34 are respectively fixedly connected to the inner side of the support bracket 32 ​​and the voice coil 33, the tweeter component 3 is also provided with Drum paper 35, the drum paper 35 is located between the support bracket 32 ​​and the voice coil 33 and the magnet 311, and the drum paper 35 is fixedly connected to the inner side of the support bracket 32, the voice coil 33 and the magnet 311 respectively.

In this embodiment, washer is the common name for spring gasket, which is called spring washer in English. Generally, manufacturers call washer "wafer", which is a fastener and a kind of standard part. The tweeter component is an inverted structure. The tweeter component of a traditional speaker is generally assembled in a manner that the magnetic circuit device is on the innermost side and the supporting bracket is on the outermost side, while the tweeter component of the present invention has the magnetic circuit device on the outermost side and the supporting bracket on the innermost side, that is, the magnetic circuit device is close to the inner side of the 5G smart speaker shell, and the supporting bracket is close to the inner center of the 5G smart speaker. This inverted tweeter component is particularly suitable for use in smaller 5G smart speakers. After the inverted tweeter component is implanted into the speaker, the lower bracket, the elastic wave and the drum paper form a tweeter resonance auxiliary sound cavity, which can greatly improve the sound quality of the tweeter component under the smaller cavity volume of the 5G smart speaker.

[0028] It can be seen from the above that the present invention provides a 5G smart speaker with an arc-shaped air duct. By arranging a 5G smart speaker shell, a bass component, a tweeter component, a main control circuit board and an arc-shaped air duct that cooperate with each other in the 5G smart speaker, the arc-shaped air duct can form a bass resonance auxiliary sound cavity with a fixed low-frequency resonance frequency with the space directly below the bass component.
