The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

The following disclosure provides many different embodiments or examples for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or uses of other materials.

Referring to fig. 1 to 3, a voice receiving device 100 for a cooking apparatus 200 according to an embodiment of the present invention includes a circuit board assembly 110, a housing 120, and a sound insulating member 130. The circuit board assembly 110 includes a microphone 111. The circuit board assembly 110 is defined within the housing 120. The housing 120 includes a first sound guide hole 121. The soundproof member 130 is disposed on a side of the circuit board assembly 110 facing the first sound guide hole 121. The soundproof member 130 includes a second sound guide hole 131. The second sound guide hole 131 communicates with the first sound guide hole 121. The microphone 111 is disposed to face the second sound guide hole 131.

Specifically, in the embodiment shown in fig. 1, the cooking apparatus 200 includes a body 210, and the voice receiving device 100 is disposed within the body 210. The first sound guide hole 121 is exposed on the surface of the body 210. The soundproof member 130 is attached to the surface of the circuit board assembly 110 in a lengthwise direction thereof, and the structure around the second sound guide hole 131 of the soundproof member 130 can completely cover a position around the microphone 111.

When a user makes a voice, the voice can be transmitted into the first sound guide hole 121, and is continuously transmitted through the second sound guide hole 131 communicated with the first sound guide hole 121, and can reach the position of the microphone 111 on the circuit board assembly 110, so that the first sound guide hole 121 and the second sound guide hole 131 are in signal communication to form a sound pickup hole, and the microphone 111 can receive the voice transmitted along the sound pickup hole.

On the basis, the sound insulation member 130 can transmit the blocking sound to the microphone 111 through the solid structure, and the situation that the microphone 111 receives the voice and other sounds transmitted along the solid structure to cause disorder of the received sounds and influence the recognition effect is avoided or reduced as much as possible, so that a good air tightness effect can be provided for the microphone 111.

In some embodiments, referring to fig. 3, the speech receiving apparatus 100 includes a glue 140. The adhesive member 140 has two sides capable of being adhesively connected to other structures, wherein one side is closely attached to the side of the circuit board assembly 110 facing the first sound guide hole 121, and the other side is closely attached to the side of the sound insulating member 130. In this way, when the noise insulator 130 blocks other noise, the degree of adhesion between the noise insulator 130 and the microphone 111 can be increased, and the effect of blocking noise transmitted in a direction other than the through hole direction of the first sound guide hole 121 by the noise insulator 130 can be increased.

Furthermore, in an embodiment, referring to fig. 3, the adhesive 140 includes a third sound guiding hole 141, the third sound guiding hole 141 corresponds to the microphone 111, the adhesive 140 is attached to the surface of the circuit board assembly 110 along its length direction, and the through hole of the third sound guiding hole 141 faces the microphone 111, and the structure around the third sound guiding hole 141 on the adhesive 140 can completely cover the position around the microphone 111, so that the third sound guiding hole 141, the second sound guiding hole 131, and the first sound guiding hole 121 are sequentially communicated to form a sound collecting hole of the microphone 111, thereby preventing the problem that the adhesive 140 blocks noise transmitted from the second sound guiding hole 131 and the microphone 111 when the adhesive 130 is used to tightly connect the sound insulating member 130 and the circuit board assembly 110, and the adhesive 140 can also block noise transmitted from directions other than the through hole direction of the first sound guiding hole 121 in cooperation with the sound insulating member 130. In one embodiment, the sound insulator 130 may be a silicone pad.

For the microphone 111, when the voice is acquired, the voice signal in the analog signal form is converted into the electric signal in the digital signal form, and the voice noise reduction technology and the recognition technology are used for processing, so that the control instruction corresponding to the voice can be recognized, the cooking device 200 can execute corresponding cooking operation according to the control instruction, and the voice control requirement of the user is met.

In the voice receiving device 100, when a user sends a voice to the cooking apparatus 200, the voice is transmitted to the microphone 111 along the first and second

sound guide holes

121 and 131, and is not transmitted in a solid state or received by the voice receiving device 100 from other through holes, so that the air tightness of the microphone 111 is improved, the voice recognition effect is improved, and the overall structure is favorable for ensuring the consistency of the voice receiving device 100 during installation.

In addition, in some embodiments, the side of the circuit board assembly 110 facing away from the microphone 111 may be provided with a sound insulation structure, so that noise transmitted from the back of the microphone 111 can be blocked.

Also, in fig. 3, the number of the microphones 111 is two, two microphones 111 are respectively disposed at positions of both ends of the circuit board assembly 110, and each microphone 111 corresponds to one first sound guide hole 121 and one second sound guide hole 131. For the circuit board assembly 110, the two microphones 111 may respectively receive voices, so that the voices received by the two microphones 111 can be compared, and in case that it is determined that the voices received by the two microphones 111 correspond to the same information, it may be determined that the voices are received without error, and thus, a corresponding control instruction may be further generated according to the voices, so that the cooking apparatus 200 performs a corresponding cooking operation according to the control instruction. In other embodiments, the number of microphones 111 may be two or more. The microphone 111 may be a BOTTOM type microphone or a TOP type microphone.

In addition, in other embodiments, the body 210 may include an interactive interface (not shown), and in the case that the user performs voice control through the voice receiving device 100 provided on the body 210, the cooking apparatus 200 may display an operation result of performing the voice control through the interactive interface to feed back related information to the user and enable the user to emit a subsequent voice for implementing the voice control according to the received feedback.

Referring to fig. 3 and 4, in some embodiments, the circuit board assembly 110 includes a recess 112 formed in the circuit board assembly 110. The groove 112 is disposed toward the first sound guide hole 121. The recess 112 receives the microphone 111 therein so that the microphone 111 does not protrude from the surface of the circuit board assembly 110, thereby eliminating the need to dig a hole in the noise insulator 130 to prevent the microphone 111 from being crushed. For the adhesive member 140, the uneven structure on the surface of the circuit board assembly 110 can be reduced, so that the problem that the adhesive member 140 cannot completely adhere to the circuit board assembly 110 due to too many dead corners when adhering to the surface of the circuit board assembly 110, and the problem that the adhesion area between the adhesive member 140 and the circuit board assembly 110 is reduced and the adhesion force is reduced can be avoided.

For the microphone 111, the sound receiving direction can be formed by the internal sound transmission structure thereof, and the sound receiving direction corresponds to the notch orientation of the groove 112. Under the condition that the notch faces the second sound guide hole 131, the direction of the notch, the direction of the through hole of the first sound guide hole 121 and the direction of the through hole of the second sound guide hole 131 are consistent and correspond to the sound receiving direction, so that the voice arriving at the position of the microphone 111 along the first sound guide hole 121 and the second sound guide hole 131 is received by the microphone 111 more easily, and accurate receiving of the microphone 111 is facilitated.

On the basis, the surface structure of the circuit board assembly 110 can be simplified through the groove 112, and the microphone 111 can be ensured to well receive the voice sent by the user, so that a broken piece is not easy to generate when the voice receiving device 100 is assembled, and the structure consistency can be good.

In this way, while it is ensured that the microphone 111 can clearly receive the voice, it is advantageous for the consistency of the structure of the voice receiving apparatus 100 when it is installed on the assembly line.

Referring to fig. 3 and 4, in some embodiments, circuit board assembly 110 includes a flashing 150. In the direction of the slot of the groove 112, the microphone 111 is arranged at the bottom of the groove 112, the flashing 150 is arranged at the slot of the groove 112, and the flashing 150 closes the slot.

In the embodiment shown in fig. 3, since the waterproof member 150 blocks the position between the second sound guiding hole 131 and the microphone 111, water vapor is not easy to reach the position of the microphone 111, and the problem of poor contact of the circuit structure in the microphone 111 caused by the water vapor flowing along the first sound guiding hole 121 and the second sound guiding hole 131 entering the microphone 111 is avoided.

Furthermore, in fig. 4, the waterproof member 150 and the circuit board assembly 110 are both plate-shaped structures, and when the waterproof member 150 seals the notch, the plate-shaped structure of the waterproof member 150 is parallel to the plate-shaped structure of the circuit board assembly 110, so that the waterproof member 150 can form the same plane with the surface of the circuit board assembly 110 having the groove 112 along the plane direction, thereby avoiding increasing convex angles or concave angles on the surface of less circuit board assemblies 110 having the groove 112, avoiding reducing the adhesion force with the circuit board assembly 110 for the adhesive member 140, and improving the adhesion degree with the circuit board assembly 110 for the sound insulating member 130.

In this way, on the premise of ensuring the structural consistency when the voice receiving apparatus 100 is installed on the assembly line, the waterproof effect on the microphone 111 can be achieved.

Referring to fig. 3, in some embodiments, the housing 120 includes an upper shell 122 and a lower shell 123. Specifically, the upper and lower housings 122 and 123 are detachably coupled and constitute the housing 120 when the upper and lower housings 122 and 123 are coupled to each other. In fig. 3, the upper and lower housings 122 and 123 may be connected to each other by a first fixing structure 160. The first sound guide hole 121 is opened in the upper case 122. The circuit board assembly 110 is fixedly coupled to the lower housing 123. With the lower housing 123 connected to the upper housing 122, the circuit board assembly 110 is located at a position between the upper housing 122 and the lower housing 123, thereby confining the circuit board assembly 110 within the housing 120.

Specifically, in the embodiment shown in fig. 3, the circuit board assembly 110 is fixed by the lower case 123 and then signal-fixedly connected by the upper case 122 and the lower case 123 so that the circuit board assembly 110 can be housed between the upper case 122 and the lower case 123, and in the case where the voice receiving effect of the microphone 111 is ensured by the voice receiving apparatus 100, the protection and fixing effects on the voice receiving apparatus 100 are achieved by the fitting between the upper case 122 and the lower case 123. Thus, the structural consistency of the voice receiving device 100 during assembly can be conveniently realized.

Referring to fig. 1, in some embodiments, the cooking apparatus 200 includes a panel 220. Specifically, in fig. 1, the panel 220 is located on a side of the cooking apparatus 200 that is easily accessible to a user, and the voice receiving device 100 is located on the panel 220, so that the voice receiving device 100 can easily receive a voice uttered by the user. On this basis, as for the upper housing 122, it can be formed on the panel 220 in an integrated structure, which can reduce the connection gaps that need to be set on the panel 220, and can not cause the problems that noise enters into the voice receiving device 100 through these connection gaps, and moisture can cause interference to the microphone 111 along these connection gaps; the upper housing 122 may also be detachably connected to the panel 220, so as to facilitate the removal of the voice receiving device 100 from the panel 220 for maintenance and replacement of internal failure components when a failure occurs in the voice receiving device 100.

For the first securing structure 160, in some embodiments, the first securing structure 160 includes a snap, a thread, a sliding slot, and the like.

Referring to fig. 2 and 3, in some embodiments, the first fixing structure 160 includes a snap connection portion 161 having a snap structure. The snap connection 161 includes a projection 162 and a hole member 163. The protrusion 162 is disposed on the upper housing 122, and the hole-fastening member 163 is disposed on the lower housing 123.

The hole member 163 and the protrusion member 162 are correspondingly disposed.

When the upper housing 122 and the lower housing 123 are connected by the first fixing structure 160, the protruding part 162 may be integrally formed through the fastening hole 1631 along the through hole direction of the fastening hole 1631 on the fastening hole 163 and be limited in the fastening hole 1631, so that the fastening hole 163 limits the protruding part 162, and the lower housing 123 limits the upper housing 122. In this way, the upper housing 122 and the lower housing 123 can be fixedly connected to each other.

In addition, in some embodiments, referring to fig. 3, the number of the snap connection portions 161 is multiple, and the multiple snap connection portions 161 are disposed on the housing 120 around the housing 120. Specifically, the protruding members 162 located on the upper casing 122 are circumferentially disposed on the periphery of the upper casing 122, the hole fastening members 163 located on the lower casing 123 are circumferentially disposed on the periphery of the lower casing 123, and one hole fastening member 163 is located for each protruding member 162.

In addition, in other embodiments, the protruding member 162 may be disposed on the lower housing 123, and the hole fastening member 163 may be disposed on the upper housing 122.

Specifically, in fig. 3, the whole structure of the hole fastening member 163 is protruded from the lower housing 123 in a ring structure, such that a fastening hole 1631 is formed in the ring of the ring structure, and a side of the ring structure away from the lower housing 123 forms a part of the protruded structure 1632 of the hole fastening member 163. When the upper housing 122 and the lower housing 123 are connected by the first fixing structure 160, the protruding part 162 is defined in the fastening hole 1631, and a part of the protruding structure 1632 of the fastening hole member 163 is close to the receiving recess 164 and can be received in the receiving recess 164 in an embedded manner, so that the whole of the fastening structure formed by the protruding part 162 and the fastening hole member 163 does not take an outward protruding shape on the voice receiving device 100 after the connection is completed. Thus, the structural strength of the voice receiving apparatus 100 can be improved, and the miniaturization design of the structure is facilitated.
