Description

Electronics with floating sound holes

technical field

The invention relates to an electronic device, in particular to an electronic device with a floating sound hole.

Background technique

In today's era of rapid technological development, portable electronic devices have become an indispensable part of the daily life of modern people. Especially mobile phones, with their thin, light, small size and easy to carry features, can make it very convenient for modern people to communicate with others by phone anytime and anywhere.

The radio mechanism of a traditional mobile phone includes a radio hole, a radio space and a microphone as a radio component, and the radio hole is arranged on the casing of the mobile phone. The sound receiving space is set in the casing and communicates with the outside world through the sound receiving hole. The microphone is arranged in the sound receiving space for receiving sound through the sound receiving space and the sound receiving hole.

During the process of collecting sound by the microphone, when the user speaks into the sound receiving hole, the user's voice will be transmitted into the sound receiving space through the sound receiving hole. After the user's voice is transmitted to the sound receiving space, the user's voice is reflected on the inner wall of the sound receiving space to generate frequency resonance. Furthermore, the resonated sound is received by the microphone.

However, the traditional sound receiving hole is arranged on the casing in the form of opening, and its position is fixed. If the opening position of the sound receiving hole is poorly designed, it will directly affect the sound receiving effect of the microphone.

In addition, due to the compactness of the radio mechanism, only a small radio space can be used. As a result, the frequency resonance effect of the sound will be poor, and the sound collection effect of the microphone will be poor.

In addition, in order to solve the problem of poor frequency resonance, some manufacturers use microphones with higher power, but the volume of microphones with higher power is also larger. Therefore, the receiving space of the electronic device is considerably occupied, and the production cost is increased.

As for other portable electronic devices using traditional radio receivers, such as personal digital assistants and digital recording devices, they will also face the above-mentioned various problems.

The floating casing has a sound receiving hole, and the floating casing is arranged in the opening in a non-fixed manner, so that the floating casing and the casing form a sound receiving space. The lifting adjustment mechanism moves in the casing and contacts the floating casing, and is used to push the floating casing to move along the opening, so that the position of the sound receiving hole can float inside and outside the opening.

According to another object of the present invention, an electronic device with a floating sound receiving hole is provided, which includes a casing, a sound receiving component, a floating casing and a lifting adjustment mechanism. The casing includes a bottom plate, a top plate and a side plate, and the top plate has a first opening. The side plate connects the top plate and the bottom plate, and has a second opening. The base plate, the side plate and the top plate define a sound receiving space, and the sound receiving components are arranged in the sound receiving space. The floating casing includes a main body and an extension. The main body has a sound receiving hole, and the extension is connected to the main body. The lifting adjustment mechanism includes a pressing component, a movable component, a fixed component and a cam component. The pressure-contact component is arranged inside and outside the housing in a manner of passing through the second opening, and one end of the pressure-contact component is exposed outside the housing for a user to apply force. The fixing component is fixed in the sound receiving space and penetrated by the pressing component. The movable component is arranged on the pressing component in a manner of moving synchronously with the pressing component, and can rotate relative to the fixed component, and the movable component is used for cam contact with the fixed component. The cam component is arranged on the movable component in a way that it can rotate synchronously with the movable component, and is used to abut against the extension part. When the user presses the touch component, the touch component and the movable component move synchronously, so that the movable component and the cam rotate synchronously relative to the fixed component, so as to push the floating casing to move along the first opening, so that the sound receiving hole can float on the First opening inside and out.

The cam component 540 is disposed on the movable component 530 in a manner to rotate synchronously with the movable component 530 for abutting against one end of the extension portion 440 .

The partition plate 550 is disposed on the pressure-contact component 510 in a manner that can move synchronously with the pressure-contact component 510 , and is located between the fixing component 520 and the side plate 240 . Wherein, the size of the partition 550 is larger than that of the second opening 240a, or the shape of the partition 550 is different from that of the second opening 240a, so as to prevent the pressure contact component 510 from falling off from the side plate 240 . The elastic component 560 is disposed between the fixing component 520 and the separator 550 . The elastic component 560 can be a spring, an elastic piece, or a combination of a spring and an elastic piece. The structure of the elastic component 560 in this embodiment is described by taking a spring as an example. In this embodiment, the lifting adjustment mechanism 500 further includes a supporting partition 570 , and the supporting partition 570 is fixed in the sound receiving space 260 to support the movable component 530 .

The above-mentioned cam assembly 540 includes a rotating shaft 540c, a first peripheral apex 540a and a second peripheral apex 540b, the first peripheral apex 540a is separated from the rotating shaft 540c by a first distance D1, and the second peripheral apex 540b is separated from the rotating shaft 540c by a first distance D1. Two distance D2.

Then, since the fixed component 520 does not move, but the elastic component 560 is compressed and accumulates a compressive elastic force, so the partition plate 550, the pressing component 510, the movable component 530 and the cam component 540 move toward the side plate synchronously due to the elastic force of the elastic component 560. 540 to move outside. At this time, the movable component 530 and the cam component 540 do not rotate relative to the fixed component 520 .

Next, when the movable component 530 and the fixed component 520 come into cam contact again, the partition plate 550 , the pressing component 510 , the movable component 530 and the cam component 540 are fixed. At this time, the sound receiving hole 420a rises out of the first opening 220a, as shown in FIG. 3 .

When the user finishes talking on the phone using the electronic device 101 of FIG. 3 , the user can press the touch component 510 again and then let go, so as to lower the sound receiving hole 420 a into the first opening 220 a, as shown in FIG. 2 .

Therefore, through the design of the lifting adjustment mechanism 500 , such as a push/push mechanism, the user can easily lift and lower the sound receiving hole 420 a in the first opening 220 a to adjust the size of the sound receiving space 260 .

However, those skilled in the art of this embodiment can also understand that the technology of this embodiment is not limited thereto. For example, the sound receiving component 300 may not be disposed corresponding to the sound receiving hole 420 a of the floating casing 400 . In addition, the electronic device 101 also includes another elastic component, which is disposed between the extension portion 440 of the floating casing 400 and the casing 200, such as between the extension portion 440 and the bottom plate 210, or Between the extension part 440 and the top plate 220 . In addition, the body part 420 and the extension part 440 can be an integrally formed structure, the contact pressure component 510, the movable component 530, the cam component 540 and the partition plate 550 can be an integrally formed structure, the bottom plate 210, the side plate 240 and the top plate 220 can be One-piece structure.
