Description

Electronic device

Technical Field

The present disclosure relates to electronic devices, and particularly to an electronic device.

Background

Along with development of technology, most electronic products, such as mobile phones and tablets, are provided with speakers to realize playing functions.

However, the conventional electronic products often have an improper layout of the speakers in the housing, which results in a large space occupied by the speakers, i.e., there is a problem that the size of the speakers limits the light and thin design of the electronic products.

Disclosure of Invention

In view of the above, it is necessary to provide an electronic device.

An electronic device, comprising:

the shell is provided with a sound outlet;

the sound production device comprises a sound production piece and a support, wherein the support is arranged in the shell, a sound channel is arranged in the support, the support comprises an inner surface, a containing groove is formed in the inner surface, the sound production piece is embedded in the containing groove, the sound production piece is provided with a sound production surface, the sound production surface faces the containing groove and forms a sound cavity with the groove wall of the containing groove in a surrounding mode, the sound cavity is communicated with the first end of the sound channel, the second end of the sound channel is communicated with the sound production hole, and the extending direction of the sound production hole and the direction of the sound production surface are arranged in an included angle mode.

According to the electronic device, the support is arranged in the shell, the accommodating groove is formed in the inner surface of the support, the sounding piece is embedded in the accommodating groove, and the sounding surface of the sounding piece faces to the accommodating groove, so that the sounding surface of the sounding piece basically converges with one of the length direction, the width direction and the height direction of the shell. The sound emitted by the sound emitting element from the sound emitting surface is transmitted from the sound emitting hole of the side wall after turning in the sound channel, which can be regarded as that the sound emitting surface of the sound emitting element is not right opposite to the sound emitting hole.

The arrangement can avoid the limitation of the bracket and the sound generating part accommodated by the bracket to the height dimension of the shell, and is favorable for the light and thin design of the electronic device in the height direction. It can be understood that the dimension of the sounding member in the thickness direction is smaller, that is, the sounding member is thinner in the thickness direction, so that the occupied space of the sounding member in the height direction of the housing can be reduced as much as possible. It should be noted that the thinning of the electronic device is not easy, because the mechanisms in the electronic device are closely matched, and one of the small changes may generate a chain reaction, rather than simply thinning the structures of the parts. In other words, it is not practical to simply thin the structure of each part of the electronic device by machining, so that many challenges are actually presented in the process of implementing the thin design of the electronic device, and finally, the layout of the speakers in the electronic device is obtained, thereby implementing the thin and miniaturized design of the electronic device.

In one embodiment, the housing has a side wall extending in a height direction, the sound emitting hole is provided in the side wall, and the receiving groove is provided in the inner surface in the height direction of the housing.

In one embodiment, the extending direction of the sound emitting hole is perpendicular to the direction of the sound emitting surface. Such an arrangement can maximally reduce the influence of the thickness dimension of the sounding member on the height-direction dimension of the housing.

In one embodiment, the sounding member has the first surface and the second surface opposite to each other along the thickness direction of the sounding member, the second surface is the sounding surface, and the thickness direction of the bracket is parallel to the height direction of the housing.

In one embodiment, the extending direction of the sound emitting hole is parallel to the sound emitting surface.

In one embodiment, the cross-sectional area of the second end of the soundtrack is greater than the cross-sectional area of the first end.

In one embodiment, the cross-sectional area of the soundtrack increases gradually in the direction from the first end to the second end. The arrangement is such that the soundtrack may modulate and amplify sound as it passes from the first end to the second end of the soundtrack.

In one embodiment, the longitudinal cross-sectional profile of the soundtrack is flared.

In one embodiment, the sounding member has dimensions in three directions of a length direction, a width direction and a thickness direction, and the sounding member has a minimum dimension in the thickness direction.

In one embodiment, the electronic device further comprises a waterproof sound-transmitting member, wherein the waterproof sound-transmitting member covers the second end of the sound channel, and the waterproof sound-transmitting member can allow sound waves to pass through and prevent liquid from entering the sound channel from the second end.

Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

Referring to fig. 1 to 5, the present utility model provides an electronic device 10, where the electronic device 10 may be a mobile phone, a camera, etc. with a playing function. The electronic device 10 includes a housing 100, a sound generating member 200 and a bracket 300. As shown in fig. 1, 2, 4 and 5, the housing 100 has a side wall 110 extending in any direction (e.g., any one of the length direction L, the width direction W and the height direction H) thereof, and the side wall 110 is provided with a sound outlet 111. For example, taking the case 100 having the side wall 110 extending along the height direction H as shown in fig. 1, 2 and 4 as an example, the stand 300 is disposed in the case 100, the stand 300 is provided with a sound channel 310, the inner surface of the stand 300 is provided with a receiving groove 320 along the height direction H of the case 100, and the sound generating member 200 is embedded in the receiving groove 320. As shown in fig. 4 and 5, the sounding member 200 may be a speaker unit, and the sounding member 200 has a minimum dimension in the thickness direction 200a compared to the dimension in the length direction L and the width direction W. The sound generating member 200 has a first surface 201 and a second surface 202 disposed opposite to each other along a thickness direction 200a thereof, the second surface 202 is a sound generating surface and faces the accommodating groove 320, as shown in fig. 5, the second surface 202 and a groove wall of the accommodating groove 320 enclose to form a sound cavity 321, the sound cavity 321 is communicated with the first end 311 of the sound track 310, and the second end 312 of the sound track 310 is communicated with the sound outlet 111.

Taking the conventional camera with playing function as an example shown in fig. 6, the sound emitting surface of the speaker therein faces the sound emitting hole 111 on the whole machine housing 100. The minimum height h1 of the product designed by the thought is dependent on the length a or width b of the speaker, but not the thickness of the speaker, i.e. the layout of the speaker is unfavorable for the light and small design of the product.

In the electronic device 10 of the present utility model, the stand 300 is disposed in the housing 100, and the surface of the stand 300 is provided with the accommodating groove 320 along the height direction H of the housing 100. For example, as shown in fig. 3, the upper surface of the bracket 300 is provided with the receiving groove 320. In other embodiments, the accommodating groove 320 may be formed in the lower surface of the bracket 300. The sounding member 200 is embedded in the accommodating groove 320, and the second surface 202 of the sounding member 200, which is a sounding surface in the thickness direction 200a thereof, faces the accommodating groove 320, as shown in fig. 4 and 5, which means that the second surface 202a of the sounding member 200 is substantially convergent with the height direction H of the housing 100, i.e., the thickness direction 200a of the sounding member 200 is convergent with the height direction H of the housing 100. The sound emitted from the sound emitting surface of sound emitting member 200 is "after turning" within track 310 and out of sound emitting aperture 111 of sidewall 110, which may be considered to be the sound emitting surface of the sound emitting member not facing the sound emitting aperture.

The arrangement can avoid the limitation of the stand 300 and the sounding member 200 accommodated therein to the height dimension of the housing 100, which is beneficial to the light and thin design of the electronic device 10 in the height direction H. It can be appreciated that, as shown in fig. 3, 4 and 5, the dimension of the sounding member 200 in the thickness direction 200a is smaller, i.e. the sounding member 200 is thinner in the thickness direction 200a, so that the space occupied by the sounding member 200 in the height direction H of the housing 100 can be reduced as much as possible.

It should be noted that the light and thin electronic device 10 is not easy because the mechanisms are closely matched, and a small change may generate a chain reaction, rather than simply thinning the parts. In other words, it is not practical to simply thin the parts of the electronic device 10 by machining, such as the iphone of apple company spends hundreds of millions of dollars in developing expenses for thinning by 1 mm, and similarly, the present utility model actually has many challenges in realizing the thin design of the electronic device 10, and finally, the layout of the speakers in the electronic device 10 is obtained, so as to realize the thin and miniaturized design of the electronic device 10.

In some embodiments, the extending direction 111a of the sound emitting hole is disposed at an angle with respect to the direction 202a of the second surface 202 (i.e., the sound emitting surface). Specifically, in the embodiment shown in fig. 5, the extending direction 111a of the sound emitting hole is substantially perpendicular to the direction 202a of the second surface 202 (i.e., sound emitting surface). The thickness direction 200a of the bracket 300 is substantially parallel to the height direction H of the housing 100, and the extending direction 111a of the sound outlet is substantially parallel to the second surface 202. Such an arrangement can maximally reduce the influence of the thickness dimension of the sounding member 200 on the height direction H dimension of the housing 100.

Referring to fig. 5, in some embodiments, the cross-sectional area of the second end 312 of the soundtrack 310 is greater than the cross-sectional area of the first end 311.

Specifically, as shown in fig. 5, in some embodiments, the cross-sectional area of the soundtrack 310 increases gradually in the direction from the first end 311 to the second end 312. More specifically, in some embodiments, the longitudinal cross-sectional profile of the soundtrack 310 is flared. Such a configuration allows the soundtrack 310 to modulate and amplify sound as it passes from the first end 311 to the second end 312 of the soundtrack 310.

Referring to fig. 3 and 5, in some embodiments, the electronic device 10 further includes a waterproof sound-transmitting member 400, such as a waterproof sound-transmitting membrane. The waterproof sound-transmitting member 400 covers the second end 312 of the sound track 310, and the waterproof sound-transmitting member 400 is capable of allowing sound waves to pass through and preventing liquid from entering the sound track 310 from the second end 312. As shown in fig. 5, the electronic device 10 further includes a dust-proof sound-transmitting member 500, such as a dust-proof sound-transmitting film, disposed in the sound outlet 111. The dustproof sound-transmitting member 500 can pass sound waves and prevent external dust from entering from the sound outlet 111.
