Problems solved by technology

[0003] According to the sound cavity structure of a smartphone disclosed in CN202020447992.3, due to the limited internal capacity of the mobile phone shell, when designing the internal sound cavity structure, it is impossible to provide a large space for it, resulting in the space of the front cavity Shrinkage will affect the sound quality and volume, and most of the existing mobile phones do not have the ability to play 3D sound quality when playing external sounds, so we propose a mobile phone with a sound cavity structure and 3D sound quality solve the problems mentioned above

Embodiment 1

[0046] Such as Figure 1-Figure 7 As shown, a mobile phone with a sound cavity structure and external 3D sound quality includes a mobile phone case 1, a soundproof sealing plate 10 and an inner sealing foam 22, and a support body 9 is provided on the inner bottom side of the mobile phone case 1, The corner of the inner side of the support body 9 is provided with a sound cavity shell 15, and the sound cavity shell 15 is fixedly installed on the inner side of the support body 9 through a fixed piece provided, and the inner middle end of the sound cavity shell 15 is provided with a sound cavity 18 , the inside of the sound chamber 18 is provided with an inner sealing foam 22, the inner sealing foam 22 is provided with a front cavity 25, the height of the front cavity 25 is between 0.4-1 mm, and the inner wall surface of the front cavity 25 is provided with a deformed groove twenty four.

[0047] The working principle of the above-mentioned technical scheme is as follows:

[004...

Embodiment 2

[0052] In another embodiment, such as figure 2 As shown, the outer end of the mobile phone housing 1 is provided with a sound outlet 5, and one side of the front chamber 25 is provided with the sound outlet 5, and the two sound outlets 5 are sealed and communicated, and the sound outlet 5 communicates with the front chamber 25, The inner inner wall surface of the sound hole 5 is covered with an inner sealing foam 22, and the sound hole 5 at one end of the mobile phone housing 1 is provided with a dust-proof net, and the surrounding of the dust-proof net is connected with the sealant of the sound hole 5. Inner wall seal connection.

[0053] By arranging the inner sealing foam 22 on the inner inner wall surface of the sound outlet hole 5, the sound insulation to the inside of the sound outlet hole 5 is realized, and the sound outlet hole 5 is used as the medium to prevent the sound from propagating through the sound outlet hole 5. Diffusion is carried out to reduce the volume ...

Abstract

The invention discloses a mobile phone with a sound cavity structure and playing 3D sound quality, and belongs to the technical field of smart phones, the mobile phone comprises a mobile phone shell, a support body is arranged on one side of the bottom end in the mobile phone shell, a sound cavity shell is arranged at the corner of one side in the support body, and the sound cavity shell is fixedly installed on one side in the support body through an arranged fixing piece; a sound cavity is formed in the middle end of the interior of the sound cavity shell, inner sealing foam is arranged in the sound cavity, a front cavity is formed in the inner sealing foam, a deformed groove is formed in the surface of the inner wall of the front cavity, the interior of the sound cavity is expanded through the design of the sound cavity, the deformed groove is formed in the sound cavity, and therefore the space of the front cavity is increased; the high-frequency cut-off point of audio frequency can be influenced by the sound box, the cut-off frequency is reduced by increasing the space, and resonance is generated by matching with the deformed groove formed in the surface of the inner wall in the front cavity, so that the resonance effect can be generated when the audio frequency is played, and therefore, the sound quality is improved, and the effect of simulating the 3D sound quality is achieved.

Description

technical field [0001] The invention relates to the technical field of smart phones, in particular to a mobile phone with a sound chamber structure and external 3D sound quality. Background technique [0002] A smart phone, like a personal computer, has an independent operating system and an independent operating space. Users can install software, games, navigation and other programs provided by third-party service providers by themselves, and can realize wireless network communication through mobile communication networks. The general term for the type of mobile phone connected. The current development trend of smartphones is to fully incorporate a number of patented technologies such as artificial intelligence and 5G, making smartphones the most widely used patented products. [0003] According to the sound cavity structure of a smart phone disclosed in CN202020447992.3, due to the limited internal capacity of the mobile phone shell, when designing the internal sound cavi...
