Detailed Description

In order to prevent a loudspeaker in equipment from being damaged due to water entering from a sound hole in the equipment with the sound hole, the loudspeaker with a waterproof function is generally installed in the equipment at present; for example, when the waterproof level of the electronic device is 50 meters, a speaker having a 5ATM (50 meters waterproof) function is required. However, the speaker having the waterproof function has the following disadvantages: the cost of the loudspeaker with the waterproof function is multiple times of that of a common loudspeaker, so that the cost of equipment is increased; the second step is as follows: the size of the loudspeaker with the waterproof function is larger than that of a common loudspeaker, and the loudspeaker is inconvenient to arrange; when the size of the equipment is limited, the waterproof structure needs to be arranged by sacrificing the performance of the loudspeaker, so that the loudspeaker is poor in communication and music playing; and the third step: the loudspeaker with the waterproof function can not discharge water completely in time after being wetted, and the residual water stain on the vibrating diaphragm of the loudspeaker can cause the loudspeaker to generate noise; and the fourth step: the process of assembling the loudspeaker with the waterproof function on the equipment is also complex, and the assembly cost of the equipment is further increased.

Aiming at the problems, the invention provides equipment with sound holes, wherein the shell of the equipment is provided with the water-blocking piece, the water-blocking piece can block the sound holes when the equipment needs to be waterproof, so that the loudspeaker is prevented from being damaged due to the fact that water enters the cavity through the sound holes, the sound holes can be opened when the equipment does not need to be waterproof, and the normal use of the loudspeaker is not influenced; therefore, the equipment with the sound hole of the embodiment does not need to use a loudspeaker with a waterproof effect, and can use a common loudspeaker with lower cost, thereby reducing the cost of the equipment; in addition, the size of the common loudspeaker is smaller than that of a loudspeaker with a waterproof function, so that the arrangement of the common loudspeaker on equipment is facilitated; or, under the condition of the loudspeaker arrangement space with the same size, the device of the embodiment can select the common loudspeaker with better sound quality.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention will be described in more detail below with reference to the accompanying drawings in the preferred embodiments of the present invention.

Referring to fig. 1, it should be noted that fig. 1 only shows the structure of the portion of the smart watch provided with the sound hole 102, since the structure does not affect the understanding. The intelligent watch of the embodiment comprises a shell 1, wherein a sealed cavity 101 is enclosed in the shell 1, and a loudspeaker 2 is installed in the cavity 101; the sound hole 102 extends through the sidewall of the chamber 101 to communicate the chamber 101 with the outside of the housing 1, that is, to communicate the chamber 101 with the outside, so that the sound of the speaker 2 can be emitted to the outside of the housing 1 through the sound hole 102.

In order to make the sound of the speaker 2 emit better to the outside, in this embodiment, as shown in fig. 2, the sound hole 102 is in a strip shape, the length direction of the sound hole 102 is parallel to the length direction of the case 1 of the smart watch, and the sound hole 102 is two strips arranged at intervals along the height direction of the case 1. The length direction of the casing 1 refers to a direction parallel to the length direction of the arm after the smart watch is worn on the arm of the user, namely, the X direction in fig. 2; the height direction of the case 1 refers to the thickness direction of the smart watch, i.e., the Z direction in fig. 1 and 2.

It should be noted that the length direction of the sound holes 102 may also be parallel to the height direction of the housing 1, and may also be parallel to the width direction of the housing 1, and there may be one, three or other number of the sound holes 102, which has the same principle as the solution of the present embodiment, and will not be described in detail here.

Referring to fig. 1 to 3, the water blocking member 3 of the present embodiment has a plate shape, the water blocking member 3 can slide on the housing 1 along the length direction of the housing 1, and the water blocking member 3 is located between the speaker 2 and the side wall of the housing 1 where the sound hole 102 is provided. In the smart watch, as shown in fig. 1, a dust screen 11 is generally disposed between the speaker 2 and the sound hole 102, and the water blocking member 3 may be disposed between the dust screen 11 and the speaker 2 or between the dust screen 11 and the sound hole 102.

In this embodiment, when the water blocking member 3 slides to the position shown in fig. 2, that is, when the water blocking member 3 is located at one side of the sound hole 102, the sound hole 102 is completely opened, and the sound of the speaker 2 can be emitted to the outside normally, in this embodiment, the water blocking member 3 is said to be located at the first position; when the water blocking member 3 slides to the position shown in fig. 3, that is, the position of the water blocking member 3 overlaps the position of the sound hole 102, the water blocking member 3 blocks the sound hole 102, and at this time, the water blocking member 3 can prevent water from entering the chamber 101 through the sound hole 102, and in this embodiment, the water blocking member 3 is referred to as being located at the second position.

In the present embodiment, the water blocking member 3 is made of a soft material, which is a material that can be rolled and stored, such as soft polyvinyl chloride, a waterproof film, and the like. Referring to fig. 3, in the present embodiment, the apparatus further includes a reel 31, the reel 31 is rotatably disposed on the casing 1, and the reel 31 is located at one side of the sound hole 102. One end of the water-blocking piece 3 is fixedly connected with the scroll 31, and when the water-blocking piece 3 slides to the first position, the water-blocking piece 3 is wound on the scroll 31; when the water blocking member 3 slides to the second position, the water blocking member 3 is released from the reel 31.

That is, in the present embodiment, the housing 1 is provided with a rotatable reel 31, and taking fig. 3 as an example, when the reel 31 rotates in the counterclockwise direction, the water blocking member 3 can be wound on the reel 31; when the reel 31 is rotated in the clockwise direction, the water blocking member 3 can be released; the switching of the water stop 3 between the first position and the second position is effected by the winding and releasing of the water stop 3 on the reel 31.

The water blocking member 3 can be wound on the reel 31 in order to slide the water blocking member 3 in a direction to approach the first position; in this embodiment, a first elastic member is disposed on the winding shaft 31, and the first elastic member can apply an elastic force to the winding shaft 31, and the elastic force drives the winding shaft 31 to rotate toward the winding water stop 3.

Specifically, in addition to the above-mentioned elastic force, the reel 31 is subjected to the pulling force of the water blocking member 3, and when the pulling force of the water blocking member 3 on the reel 31 is greater than the elastic force, the reel 31 rotates in a direction to release the water blocking member 3, so that the water blocking member 3 can slide in a direction close to the second position; when the pulling force of the water blocking member 3 on the reel 31 is smaller than the elastic force, the reel 31 rotates in the direction of winding up the water blocking member 3, so that the water blocking member 3 slides in the direction close to the first position and is wound up on the reel 31.

In this embodiment, the first elastic member is a coil spring, or a clockwork spring. When the water blocking piece 3 slides towards the direction close to the second position, the coil spring stores energy; when the water blocking member 3 slides in a direction approaching the first position, the coil spring urges the spool 31 to rotate due to its elastic recovery, thereby winding the water blocking member 3 on the spool 31. It should be noted that the coil spring may be an existing product, and the installation on the reel 31 may refer to the prior art, and will not be described in detail herein.

By providing the above-described spool 31 on the housing 1 and winding the water stop 3 onto the spool 31, the water stop 3 of the present embodiment will have a smaller footprint when in the first position than a rigid water stop 3 described below, thereby facilitating its deployment on equipment of generally limited size.

Referring to fig. 2 to 4, the wiper portion of the present embodiment includes a plurality of wiper strips 4, each wiper strip 4 is arranged at intervals along the sliding direction of the water blocking member 3, as shown in fig. 3, when the water blocking member 3 is located at the second position, each wiper strip 4 abuts against the outer side surface of the water blocking member 3; in this embodiment, there are two wiper strips 4, and it should be noted that there may be one, three or more wiper strips 4.

In the present embodiment, as shown in fig. 2, the longitudinal direction of each wiper strip 4 is orthogonal to the sliding direction of the water blocking member 3; it should be noted that each wiper strip 4 may also be arranged obliquely, and it is sufficient that it covers the water blocking member 3 in the length direction of the water blocking member 3, that is, the wiper strip may extend vertically downward or obliquely downward from the top end of the water blocking member 3 to the bottom end of the water blocking member 3.

In the present embodiment, as shown in fig. 2 to 4, each wiper strip 4 is located within the length of the sound hole 102. Or, in the longitudinal direction of the housing 1, the wiper strips 4 do not exceed both ends of the sound hole 102. Through the length within range that will scrape water strip 4 setting at phonic pore 102, scrape water strip 4 and strike off the water stain back on the water blocking piece 3, water can outwards flow out phonic pore 102, therefore the good water discharge of general ability.

In the present embodiment, as shown in fig. 3 and 4, each wiper strip 4 has a triangular cross section perpendicular to its longitudinal direction, and the tip of each wiper strip 4 abuts against the outer side surface of the water stop 3. Through the most advanced and the lateral surface butt of the piece 3 that blocks water of scraping the water strip 4, strike off that can be better and block water stain on the 3 lateral surfaces of water.

Generally speaking, through setting up foretell each strip 4 of scraping, be stained with water at the piece 3 that blocks water, open the open in-process of the piece 3 that blocks water and make the sound hole 102, scrape the water spot that the water portion can scrape on the piece 3 lateral surface that blocks water, avoid water to remain on equipment, avoid causing the influence to electronic components on the equipment.

While the sound hole 102 is made waterproof by the water blocking member 3, the present embodiment also provides a structure for optimizing the sound quality of the speaker 2 by the water blocking member 3.

In this embodiment, one of the water blocking member 3 and the housing 1 is provided with a limiting unit, the other of the water blocking member 3 and the housing 1 is provided with a positioning unit, and the positioning units are a plurality of units arranged at intervals along the sliding direction of the water blocking member 3. The water-blocking piece 3 is fixed on a third position corresponding to the positioning unit through the matching of the limiting unit and each positioning unit; when the water blocking member 3 is located at each third position, the water blocking member 3 blocks a part of the sound hole 102.

That is, when the position limiting unit is disposed on the water blocking member 3, a plurality of positioning units are disposed on the housing 1 at intervals along the sliding direction of the water blocking member 3. When the limiting unit is arranged on the shell 1, the plurality of positioning units are arranged on the water-blocking piece 3 at intervals along the sliding direction of the water-blocking piece 3. Wherein, the positioning units correspond to the third positions one by one; specifically, when the third position is one, the number of the positioning units is one, when the number of the third positions is two, the number of the positioning units is two, and when the number of the third positions is two, the number of the positioning units is three. When the position limiting unit is matched with the positioning unit, the water blocking member 3 stays at a third position corresponding to the positioning unit.

In the present embodiment, the limiting unit is disposed on the water blocking member 3, and the positioning unit is disposed on the housing 1. It should be noted that the limiting unit is disposed on the housing 1, and the positioning unit is disposed on the water blocking member 3, which have the same principle as the limiting unit, and will not be described again in this embodiment.

In this embodiment, the above-mentioned limiting units and the positioning units are arranged, so that the water blocking member 3 can be stopped at different third positions by the cooperation between the limiting units and the positioning units, respectively, and fig. 5 and 6 show two different third positions. When the water blocking member 3 is in the third position, the water blocking member 3 will partially shield the sound hole 102; or, the sound hole 102 is partially opened when the water blocking member 3 is located at the third position. And when the water blocking member 3 is located at a different third position, the water blocking member 3 blocks the sound hole 102 by a different length.

When the water stop 3 is in the third position the helmholtz resonance frequency point of the front cavity of the loudspeaker 2 will change compared to when the water stop 3 is in the first position. And the water barrier 3 is in a different third position, the point of the helmholtz resonance frequency of the front cavity of the loudspeaker 2 will also be different.

That is, the formants of the frequency response curve of the speaker 2 can be set to different frequencies depending on the length of the sound hole 102 blocked by the water blocking member 3. In other words, when the water blocking member 3 blocks the sound holes 102 having different lengths, the frequency response curve of the speaker 2 reaches the formants at different frequencies. Referring to fig. 7, three curves I, II, and III in fig. 7 are frequency response curves of the speaker 2 when the water blocking member 3 is located at three different third positions, respectively, and it can be seen that the frequencies of the frequency response curves of the speaker 2 reaching the formants are different when the water blocking member 3 is located at the different third positions. And the frequency at which the frequency response reaches the formants is a more prominent frequency in the sound emitted by the loudspeaker 2.

In this embodiment, three positioning units are disposed on the housing 1, that is, three corresponding third positions are provided, and when the water blocking member 3 is located at the three third positions respectively, the frequency at which the frequency response curve of the speaker 2 reaches the formant is close to the frequency of the human voice, the frequency of the percussion music and the frequency of the metal musical instrument, so that the device can play a role in highlighting the human voice, the percussion music and the playing effect of the metal musical instrument.

It should be noted that the number of the positioning units may be one, two, four or more, which has the same principle as the solution of the present embodiment and is not described in detail herein; moreover, the structure that the water blocking member 3 stays between the first position and the second position can also adopt the matching of the limiting unit and the positioning unit, and the details are not repeated herein.

In this embodiment, referring to fig. 10, the limiting unit of this embodiment is an insertion rod 33, the insertion rod 33 is supported on the water blocking member 3 through a second elastic member 34, the positioning unit includes an insertion slot 104 disposed on the housing 1, and the insertion rod 33 can be driven by the second elastic member 34 to be inserted into the insertion slot 104.

In a specific structure, referring to fig. 10, a blind installation hole 301 is formed in the water blocking member 3, and the rod 33 includes a round ball section 332 and a cylindrical section 331 connected in series; the cylindrical section 331 is inserted into the blind mounting hole 301 and is capable of sliding within the blind mounting hole 301.

The second elastic member 34 of the present embodiment is a spring, and the spring abuts between the bottom surface of the mounting blind hole 301 and the end surface of the cylindrical section 331. It should be noted that other elastic components can be used for the second elastic member 34.

Referring to fig. 10, the bottom surface of the slot 104 of the present embodiment is a truncated sphere, i.e., a sphere with a segment cut away; and the diameter of the sphere in which the slot 104 is located is larger than the diameter of the spherical segment 332.

Based on the above structure, when the user pushes the operation block 32 to drive the water blocking member 3 to slide, the insertion rod 33 will slide along with the water blocking member 3, and when the insertion rod 33 slides to be opposite to a certain slot 104, the insertion rod 33 is inserted into the slot 104 under the push of the second elastic member 34; when no external force pushes the water blocking member 3, the inserted link 33 will not be pulled out from the slot 104, so that the water blocking member 3 will stay, and the position where the water blocking member 3 stays at this time is the third position corresponding to the slave slot 104 in this embodiment; when the user pushes the operation block 32 again to drive the water blocking member 3 to slide, the spherical surface of the slot 104 can drive the insertion rod 33 to compress the second elastic member 34, so that the insertion rod 33 can be pulled out from the slot 104.

In this embodiment, the insertion rod 33 is configured to include the spherical segment 332 and the cylindrical segment 331, and the cylindrical segment 331 is slidably engaged with the blind installation hole 301, so as to facilitate installation of the second elastic member 34. Through the matching of the round ball section 332 and the slot 104, when the round ball section 332 slides through the slot 104, the round ball section 332 can be inserted into the slot 104 under the pushing of the second elastic piece 34, after the round ball section 332 is inserted into the slot 104, and when the water blocking piece 3 is pushed again, the round ball section 332 and the cylindrical section 331 can be driven by the spherical surface of the slot 104 to compress the second elastic piece 34, so that the round ball section 332 can slide out from the slot 104. That is, the user only needs to push the operation block 32 to realize the engagement of the insertion rod 33 with the different insertion slot 104. The inserted link 33 does not need to be manually inserted into the slot 104 or the inserted link 33 does not need to be taken out of the slot 104, so that the use is convenient for users.

In summary, in the device with sound holes of the present embodiment, the water blocking member 3 is disposed on the housing 1, and the water blocking member 3 can block the sound holes 102 when the device needs to be waterproof, so as to prevent water from entering the chamber 101 through the sound holes 102 to damage the speaker 2, and can open the sound holes 102 when the device does not need to be waterproof, so as not to affect the normal use of the speaker 2; because the device of the embodiment can plug the sound hole 102 when waterproofing is needed, and the loudspeaker 2 is prevented from being damaged due to the inflow of water through the sound hole 102, after the device adopts the sound hole 102 waterproofing mechanism of the application, the loudspeaker 2 with waterproofing effect is not needed to be used, but the common loudspeaker 2 with lower cost can be used, so that the cost of the device can be reduced; in addition, since the size of the general speaker 2 is smaller than that of the speaker 2 having the waterproof function, the arrangement of the general speaker 2 on the device is facilitated, and under the same size, the general speaker 2 has better performance in terms of conversation and music playing compared with the speaker 2 having the waterproof function.
