Example 2

Referring to fig. 2 to 4, the present invention provides a horn structure for a robot, which includes a third housing 3, a fourth housing 4 and a horn module according to embodiment 1. The third housing 3 is a part of the outer shell of the robot, and the fourth housing 4 is connected to the robot body 7. For example, the fourth housing 4 may be installed inside the robot body 7, so that the connection portion 41 is located at a connection position of two adjacent portions of the robot, which is beneficial to hiding the sound outlet hole 411.

A connecting part 41 is arranged on the fourth shell 4, and the connecting part 41 is connected with the third shell 3 to form an accommodating cavity; the connecting portion 41 is provided with a sound outlet 411. Since the connecting portion 41 is located at the connecting portion of the third casing 3 and the fourth casing 4, the sound outlet 411 is easily hidden. Of course, in the implementation, the connection portion 41 may be disposed on the third housing 3, and the fourth housing 4 may be connected to the connection portion 41 to form the accommodating chamber.

The horn module is installed in the accommodating cavity, and forms a second sound cavity 5 with the third shell 3 and the connecting part 41. The second sound cavity 5 is located at one side of the housing 1 having the mounting hole 12, and the sound outlet hole 411 is communicated with the second sound cavity 5. In this way, the speaker module can generate sound and transmit the sound from the sound output hole 411 through the second sound cavity 5. So, can enough guarantee be convenient for with go out sound hole 411 and hide, do not influence the outward appearance molding of robot, can guarantee the effect of raising one's voice of loudspeaker module again.

In a preferred embodiment, the connecting portion 41 is disposed around the second sound cavity 5 along a connection between the third casing 3 and the fourth casing 4. Thus, the sound outlet holes 411 can be disposed at different positions and directions of the connecting portion 41 as needed, and since the sound outlet holes 411 are disposed on the connecting portion 41 between the third casing 3 and the fourth casing 4, the overall appearance of the robot is not affected no matter how the area, position and direction of the sound outlet holes 411 are adjusted on the connecting portion 41, and the presence of the horn 2 can be weakened.

As a preferred embodiment, the loudspeaker module further comprises a damping component 6, and the damping component 6 is installed between the loudspeaker module and the inner wall of the accommodating cavity, that is, the loudspeaker module is connected with the wall of the accommodating cavity through the damping component 6. Specifically, damping part 6 is damping gasket, damping spring or rubber circle etc. wherein, damping gasket can adopt silica gel or rubber class material to make, damping part 6 is located the loudspeaker module with between the wall in holding chamber. Specifically, the vibration damping member 6 may be sleeved on a bolt for connecting the horn module and the accommodating cavity. Through setting up damping part 6, can prevent that the vibration of loudspeaker module from transmitting to the robot housing on, guarantee the completeness of tone quality.

In a preferred embodiment, the horn module is hermetically connected to the connecting portion 41. Thus, the sealing property of the second sound cavity 5 can be ensured, so that the second sound cavity 5 has a good sound transmission function. In specific implementation, the horn module may be sealed with the connection portion 41 by means of dehydration bonding or ultrasonic welding, or may be sealed by means of a sealing ring. Meanwhile, since the second sound chamber 5 has a certain sealing property, the sound coming out through the speaker 2 can be transmitted out through the sound outlet hole 411, and the sound effect can be ensured without directly facing the sound outlet hole 411 to the speaker 2.

In a preferred embodiment, a side of the fourth casing 4 away from the third casing 3 is provided with a connecting lug. The connecting lug is used for connecting with the robot, and particularly, the fourth shell 4 is partially positioned inside the robot body. Specifically, a connection hole may be provided in the connection lug (not shown in the drawings), and the connection lug may be connected to the robot by a bolt.

As a preferred embodiment, the number of the sound emitting holes 411 is plural. Specifically, the sound emitting hole 411 may be provided on the front side of the robot as needed so that a sufficiently large sound emitting area can be secured right in front of the robot.

In specific implementation, the shape of the third housing 3 may be designed according to the shape of the robot, for example, the third housing 3 is designed to be the shape of a certain part of the robot, such as an arm, a leg, a face, or the like. Thus, the connection between the sound outlet hole 411 and two parts of the robot, such as the connection between the arm and the trunk, the connection between the leg and the trunk, and the connection between the face and the head, can be made, of course, also be disposed at the connection between the head and the trunk, so as to be beneficial to hiding the sound outlet hole 411.

Example 3

Referring to fig. 5, the present embodiment provides a robot, which includes a robot body 7 and a horn structure in embodiment 2; the horn structure of the robot is installed on the robot body 7, the third shell 3 forms a part of the outer shell of the robot, the fourth shell 4 is installed inside the robot body 7, specifically, the fourth shell 4 is partially located inside the robot body 7, and the connecting portion 41 is located outside the robot body 7, so that sound can be smoothly transmitted through the sound transmission hole 411. Further, the third housing 3 is an arm part of the robot; the fourth shell 4 is fixedly connected with the robot body 7. The sound emitting hole 411 is located at the front side of the robot. Set the horn structure to the shape of robot arm, can furthest reduce the influence of horn structure to the robot outward appearance to satisfy the robot to the requirement of different figurations, can solve current horn structural design and have the intensive sound hole 411 of going out of large tracts of land and influence the condition of robot outward appearance.

In addition, since the connection portion 41 where the sound outlet hole 411 is located between the body and the arm of the robot, the sound outlet hole 411 is hidden. Meanwhile, the large voice output area in front of the robot can be ensured, and a good voice effect is ensured.

During specific implementation, because the loudspeaker module is independent part, be convenient for freely change loudspeaker 2's model, adjust the area, the position and the play sound direction of sound hole 411 as required. The overall appearance of the robot cannot be influenced, the existence sense of the loudspeaker 2 can be greatly weakened, the integrity and the harmony of the appearance of the robot are guaranteed, and meanwhile the effect of the sound box can be perfectly guaranteed.
