Description

Waterproof earphone

Technical Field

The present invention relates generally to the field of earphone devices, and more particularly, to a waterproof earphone.

Background

With the wide use and continuous development of earphones, the waterproof requirement on the earphones is gradually improved. At present, the waterproof protection of the rear cavity of the earphone is mainly realized by a mesh (also called a tuning net). Particularly, the waterproof function is realized by covering the mesh on the earphone sound adjusting hole. The density of the mesh cloth determines the waterproof effect to a great extent. The less screen cloth of ventilative volume can realize higher level waterproof, but screen cloth density too high can influence the acoustic performance of earphone. In particular, when the earphone has a larger speaker and requires more air permeability of the rear cavity to meet the acoustic performance requirement, the design of waterproofing by the density of the mesh fabric will affect the acoustic performance of the earphone. In theory, structural designs may be employed for waterproofing, such as adding a separate back volume to the earphone for isolating the back volume of the speaker. Although water protection can theoretically be achieved by using this additional separate rear chamber design, this separate rear chamber design requires more installation space. Under the design condition of higher stacking size requirement, the requirement of larger structural space cannot be met.

Therefore, there is a need for an improved technology capable of better solving the waterproof problem in a limited structural space of the earphone while ensuring the acoustic performance of the earphone.

However, it will be appreciated that the waterproof cover may also be made of any material commonly used in the production field.

Fig. 3 illustrates a perspective view of an earphone housing portion 220 in a waterproof configuration in accordance with one or more embodiments of the present invention. As shown, the earphone housing portion 220 is provided with two holes 222 for forming elongated through holes on the inside of the housing. It should be noted that the number of the holes provided on the earphone housing 220 of the present invention is not limited to two, and may be more than two. Fig. 3 gives an example of only two holes for a principle explanation.

Fig. 4 shows a perspective view of a waterproof cover 240 in a waterproof structure according to one or more embodiments of the present invention. FIG. 5 is a top view of the waterproof cover of FIG. 4; FIG. 6 is a rear view of the waterproof cover of FIG. 4; fig. 7 is a right side view of the waterproof cover of fig. 4. The structure of the waterproof cover will be described in detail below with reference to fig. 4 to 7.

The waterproof cover 240 includes a tuning hole (i.e., a vent) 242, a first groove 244, a second groove 246, and a third groove 248. The tuning hole 242 is a through hole penetrating the waterproof cover. The first groove 244, the second groove 246, and the third groove 248 are provided on one side surface of the waterproof cover 240 connected to the earphone housing 220. A first groove 244, a second groove 246, and a third groove 248 are disposed around the tuning port 242.

Wherein the first recess 244 communicates with the two holes 222 in the direction of the elongated through hole (see fig. 8). For example, the first groove 244 may have a shape that gradually narrows and then gradually widens from one side thereof to the other side thereof. The second groove 246 may have a curved shape around the tuning hole 246. The second groove 246 communicates with the first groove 244. For example, the second groove 246 communicates with the first groove 244 at an end side position of the first groove 244 near the two holes 222. It will be appreciated that the shapes and attachment locations of the first and second grooves 244, 246 in the waterproof cover of the present invention in fig. 4 are exemplary. The shape of the first and second grooves 244, 246 and the location of the connection therebetween may vary and is not limited to the specific shapes and connection locations shown.

One end of the third groove 248 communicates with the tuning hole 242 and the other end communicates with the second groove 246. Also, the surface of the third groove 248 is designed to be higher than the surface of the second groove 246. The shape of the third groove 248 may be straight as shown, curved with a certain curvature, or other shapes. This structural arrangement of the tuning hole 242, the third recess 248 and the second recess 246 forms a "step" on the front side of the tuning hole 242. The step can block the flow of water into the tuning hole 242. The height of this step (i.e., the difference in height between the surface of the third recess 248 and the surface of the second recess 246) may be appropriately designed as desired to ensure that the tuning hole 242 remains in only gaseous communication with the second recess 246 via the third recess 248. For example, the height of the step may be set to both block the flow of water into the tuning hole 242 and allow the tuning hole 242 to maintain gas communication with the second groove 246 via the third groove 248. The surface height of the first groove 244 may be the same as the surface height of the second groove 246. Thus, the tuning hole 242 may be in gaseous communication with the first groove 244 via the third groove 248 and the second groove 246.

The waterproof cover 240 is provided with a boss 250. The shape of the boss 250 is defined by the tuning hole 240, the first groove 244, the second groove 246 and the third groove 248 of the waterproof cover. For example, the boss 250 has a corresponding protruding portion at a narrowed portion corresponding to the first groove 244 and a corresponding inclined portion at a widened portion corresponding to the first groove 242. In other words, the inclined portion may be located, for example, in a downstream direction from a position where the first groove 244 communicates with the second groove 246 such that an inclined surface of the inclined portion faces in the direction of the hole 222. The inclined surface of the inclined portion can buffer the water flow flowing in from the hole 222, so that the waterproof effect of the waterproof structure is better. The surface of the boss 250 is higher than the surface of the waterproof cover 240, and the boss 250 may block direct communication between the first groove 244 and the tuning hole 242, so that the first groove 244 can maintain gas communication with the tuning hole 242 only via the second groove 246 and the third groove 248.

Fig. 8A illustrates a front view of the waterproof structure of fig. 2. Fig. 8B shows a sectional view taken along line a-a' in fig. 8A of the waterproof structure. Fig. 9A shows a top view of the waterproof structure of fig. 2. Fig. 9B shows a sectional view taken along line B-B' in fig. 9A. The water flow path defined by the earphone housing together with the waterproof cover is described in further detail below with reference to fig. 8A-9B.

As shown, in the assembled waterproof configuration, the two holes 222 in the earphone housing 220 cooperate with the first and second grooves 244, 246 in the waterproof cover 240 to define a water flow path. The water flow channel comprises a first water flow channel (shown as an arrow (r) -and-r) and a second water flow channel (shown as an arrow (r) -and-r). It is to be understood that the arrows indicating the water flow paths in the drawings are for illustrative purposes only, and are not intended to be exclusive in terms of the inflow and outflow directions of the water flow. The water flow can flow in from either of the two holes and out from the other hole.

For example, a first water flow path is defined by both apertures 222 and first recess 244, and a second water flow path is defined by both apertures 222 and second recess 246. Wherein the first water flow passage can be used as a main passage, and the second water flow passage can be used as an auxiliary passage. When water enters the waterproof structure from one hole, most of the water can flow out of the other hole through the first water flow channel, and a small part of the water can flow out of the other hole through the second water flow channel. The layout and configuration of the first groove 244, boss 250, tuning hole 242 have been described in detail above. With this arrangement, the first water flow passage is generally capable of ensuring that water flows in from one hole and out from the other hole without passing through the tuning hole. Furthermore, due to the unique "stepped" structure of the present invention described above, the second water flow channel is generally able to ensure that water does not flow into the third recess 248, thereby blocking the water flow from entering the tuning hole 242. Through the first and second water flow channels, the water flow entering the waterproof structure from the hole in the earphone housing can be guided to bypass the tuning hole. I.e. the tuning hole is only in gas communication with the hole in the earphone housing.

Fig. 10A shows a front view of the earphone housing 220, and fig. 10B shows a sectional view taken along the line C-C' in fig. 10A. As shown, a groove structure (e.g., first structure 224 and second structure 226) may be provided on the earphone housing 220 to mate with a boss on the waterproof cover 240 to enable the boss 250 to interact with when the earphone housing 220 is assembled with the waterproof cover 240.

In practical application, the utility model discloses a waterproof construction even under the too big extreme condition of rivers, also can the at utmost realize blockking to the rivers to prevent rivers to the tuning hole and cover on the tuning net on the tuning hole as far as. Therefore, the utility model discloses a tuning net among the waterproof construction need not to adopt the screen cloth material of high density, but can adopt the higher screen cloth of gas permeability or similar material. Therefore, the utility model discloses a waterproof construction can keep the acoustic performance of earphone, for example acoustic frequency response and ANC performance when guaranteeing waterproof. Furthermore, the utility model discloses a waterproof construction's design has further solved the waterproof problem in the earphone that the loudspeaker size surpassed 10 millimeters to can reach i px 5's waterproof requirement.

Fig. 11 shows a schematic partial top view of a waterproof cover according to one or more embodiments of the present invention in a design in which only one water flow channel is provided. As shown, the waterproof cover is provided with two grooves 1102 and 1104. The two ends of the recess 1102 may communicate with two holes in the earphone housing. One end of the groove 1104 communicates with the tuning hole 1106 and the other end communicates with the groove 1102, and the surface of the groove 1104 is higher than the surface of the groove 1102, thereby constituting a "step" structure to prevent water entering the waterproof structure from the hole in the earphone housing from flowing onto the tuning hole 1106.

It will be appreciated that the waterproof structure of the present invention is not limited to the exemplary waterproof structure shown in the drawings, but that many alternative implementations are possible. For example, the number and shape of the holes on the earphone shell, the number and shape of the grooves on the waterproof cover, the shape of the boss and the number and shape of the corresponding water flow channels can be adjusted differently according to the different earphones.
