Description

Mobile phone cover for enhancing loudspeaker output and microphone input sound

Technical Field

The utility model relates to a this kind of cell-phone cover technical field, in particular to strengthen cell-phone cover of speaker output and microphone input sound.

Background

With the rapid development of smart phones, mobile phones are more and more popular. The mobile phone cover can be used as a decoration, so that the mobile phone becomes more attractive, and meanwhile, the mobile phone cover also has the functions of protecting the mobile phone, preventing falling, scraping, water and shock, and therefore, the mobile phone cover is more and more popular to use.

When people use the mobile phone, the front of the mobile phone faces to the user, the speaker port of the mobile phone is generally arranged below the mobile phone, so that sound transmitted by the speaker port is scattered when being transmitted to the front of the mobile phone from the lower part of the mobile phone, and the sound intensity is greatly reduced after the sound is scattered, so that the sound transmitted to ears of the user is greatly reduced. People who have poor hearing or like listening to music want to have higher volume and stronger sound effect so as to be able to carry out normal conversation or enjoy music in downtown. In real life, a sound box is often used for amplifying sound or enhancing sound effect, however, the sound box is inconvenient to carry around.

The microphone hole of the mobile phone is generally arranged below the mobile phone and is symmetrical to the loudspeaker hole, when a user speaks the mobile phone by holding the mobile phone, the user also needs to speak while listening to the voice, the mouth of the user is a certain distance away from the lower surface of the mobile phone, the voice spoken from the mouth is scattered when the voice is recorded into the microphone hole during speaking, the voice input from the microphone is very small, and sometimes even the voice cannot be recognized or recognized wrongly.

The conventional mobile phone cover is provided with a speaker hole and a microphone hole at positions corresponding to a speaker hole and a microphone hole of a mobile phone, when a sound speaker outputs sound, the sound is still transmitted from a lower speaker hole vertical to the front of the mobile phone instead of being directly transmitted from an outlet at the front, and the sound still has larger dispersion loss when transmitted from the lower outlet to the front, so that the received sound is very small and the sound effect is poor; the microphone input port is not in front of the mobile phone, and the spoken sound is easy to disperse and distort because the input inlet cavity is not relatively closed.

In addition, in the video phone, in order for the other party to see the face of the other party, the mobile phone needs to be kept at a long distance from the face of the other party, the intensity of the sound transmitted to the ears of the other party is weaker, the sound is harder to hear, and the sound input by the microphone is poor.

Therefore, there is a need for a mobile phone cover that enhances the speaker output and the microphone input sound.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the existing research, the utility model provides a mobile phone cover for enhancing the sound output of a loudspeaker and the sound input of a microphone, which has an integrated structure and an ingenious design, and the arrangement of a fan-shaped loudspeaker enhancing sound transmission cavity communicated with a loudspeaker hole strengthens the volume and the sound effect of the sound emitted by the loudspeaker from multiple aspects, so that the sound of the mobile phone is finally larger and the sound effect is better; the arrangement of the fan-shaped microphone strengthening sound transmission cavity communicated with the microphone hole enables input sound to be gathered, less dispersion and noise are generated, and sound pickup is larger and more accurate. In order to achieve the above-mentioned functions, the above technical problems of the present invention can be solved mainly by the following technical solutions:

the utility model provides a strengthen cell-phone cover of speaker output and microphone input sound, including lower surrounding portion, go up surrounding portion, left surrounding portion, right surrounding portion, back surrounding portion, lower surrounding portion lower part has connect and has strengthened the biography sound chamber, strengthens the biography sound chamber opening forward, lower surrounding portion left part and right part symmetry are opened there are microphone hole and speaker hole, microphone hole and speaker hole communicate with each other with strengthening the biography sound chamber, lower surrounding portion, go up surrounding portion, left surrounding portion, right surrounding portion, back surrounding portion, strengthen the biography sound chamber structure as an organic whole.

Further, strengthen the sound conduction chamber and include the arc that meets with back enclosure afterbody, with left side enclosure and the fan-shaped right side enclosure that the afterbody of right enclosure meets, fan-shaped baffle, the left and right ends of arc meet with left side enclosure, fan-shaped right side enclosure respectively, fan-shaped baffle lower extreme meets with the arc, fan-shaped baffle upper end meets with lower enclosure.

Furthermore, the lower surrounding part, the arc-shaped plate, the fan-shaped left surrounding part and the fan-shaped partition plate form a microphone reinforced sound transmission cavity, and the lower surrounding part, the arc-shaped plate, the fan-shaped right surrounding part and the fan-shaped partition plate form a loudspeaker reinforced sound transmission cavity.

Furthermore, the microphone enhanced sound transmission cavity and the loudspeaker enhanced sound transmission cavity are fan-shaped enhanced sound transmission cavities.
