In particular, the sound box structure 10 includes a sound box housing 11, where the sound box housing 11 is an empty housing with two opposite ends open respectively, and the reflective cover 12 is adaptively clamped on one opening on the sound box housing 11, so that the reflective cover 12 is at the opening, the corresponding end of the sound box housing 11 is closed, and the speaker 13 is adaptively clamped on the other opening on the sound box housing 11, so that the speaker 13 is at the opening, the corresponding end of the sound box housing 11 is closed, and further, in the internal space of the sound box housing 11, a closed and independent space is formed, in this embodiment, the space is used as a sound cavity of the sound box structure 10, called a sound box sound cavity, compared with the prior art, the sound box sound cavity is separately arranged, and the interference effect on the sound quality is not caused by the existence of devices in the interior, and the space of the sound box sound cavity is sufficiently large, so that the speaker 13 installed at the bottom of the sound box sound cavity can fully exert the acoustic performance, thereby ensuring that the sound quality played by the sound box structure 10 is not just a simple loudspeaker, and more satisfying the pursuing of the user for the sound quality.

It should be noted that, in order to describe the microphone and speaker integrated machine in this embodiment in an image, the vertical direction is taken as an example, and the structure of the specific microphone and speaker integrated machine may depend on the actual situation.

Referring to fig. 2 and 3, the center of the side of the reflective cover 12 remote from the microphone structure 20 preferably protrudes into the sound box cavity, forming a tapered interior top surface 121 at the top of the sound box cavity.

The reflecting cover plate 12 is located at the junction of the sound box structure 10 and the microphone structure 20, one side (the surface shown in fig. 2) is opposite to the microphone structure 20, the center of the other side is protruded towards the interior of the sound box cavity, so that the inner top surface of the sound box cavity is protruded from the center to the edge, a downward conical surface is formed to form a cone at the top of the sound box cavity, when the loudspeaker 13 located at the bottom of the sound box cavity plays sound, a part of sound propagates to the top of the sound box cavity and is reflected by the top, at this time, if the top is conical, the sound will be reflected to different directions and spread all around, the downward reflection of the sound is avoided, the interference or the sound short circuit phenomenon is formed with the played original sound, the purity of the sound is improved, and the design of the sound box cavity is further optimized, so that the sound quality of the sound box structure 10 is further improved.

In the microphone and sound box integrated machine, sound picked up by a microphone is amplified by the sound box and then is transmitted out, and the sound can be reflected by surrounding objects or the sound with the same frequency can be transmitted to the microphone again by the sound box integrated machine, so that the sound with the same frequency is picked up again by the microphone and amplified again, and a strong self-feedback effect, namely a self-excitation effect, is generated after repeated amplification for a plurality of times, and then continuous and continuously reinforced sound with the same frequency, namely a howling phenomenon, is emitted in the sound box.

With continued reference to fig. 1, preferably, in order to avoid the above phenomenon, the microphone and speaker integrated machine further includes a soft rubber pad 30, where the soft rubber pad 30 is disposed at the connection between the microphone structure 20 and the speaker structure 10.

In order to further improve the sound quality of the sound box structure 10, a bass radiation assembly 14 is further arranged in the sound box structure 10, and the bass radiation assembly 14 can enable the bass frequency range of the loudspeaker 13 to be submerged to lower frequency, so that the bass sound quality of the sound box structure 10 can be obviously improved. Specifically, in order to ensure the sealing of the sound cavity of the sound box during design, a mounting hole 111 matched with the bass radiation assembly 14 may be provided on the sound box shell 11, so that the bass radiation assembly 14 is just clamped in the mounting hole 111. At the same time, two opposite bass radiation assemblies 14 are arranged such that the bass sound waves radiated by the two bass radiation assemblies 14 propagate from two opposite directions, and the generated vibrations cancel each other out, thereby avoiding howling by the microphone structure 20.

Preferably, in order to facilitate the handheld microphone and speaker integrated machine, the speaker housing 11 may be designed as a column, and two opposite openings are disposed on the upper and lower end surfaces of the column, so as to connect the microphone structure 20 on the upper end surface, and the speaker 13 disposed downward on the lower end surface, and two opposite bass radiation assemblies 14 are disposed on the side surfaces of the column, so that the sound of the sound cavity of the speaker can be propagated from two sides.

The bass radiation assembly 14 includes a bass radiation stand 142 and a bass radiation emitter 141, wherein the bass radiation stand 141 can make the bass frequency range of the loudspeaker 13 to lower frequency, but because the bass radiation stand 141 is limited by materials, the bass radiation stand 142 can be installed outside the bass radiation stand 141 to protect and support, and the bass radiation stand 142 can be a mesh cover matched with the shape of the bass radiation stand 141 in order not to influence the radiation of sound. During assembly, the bass radiator 141 can be clamped in the mesh enclosure, so that the stability of the bass radiator 141 and the sealing performance between the edge of the bass radiator 141 and the edge of the mesh enclosure are ensured, the mesh enclosure is clamped in the mounting hole 111, and the sealing performance of the sound cavity of the sound box can still be ensured on the premise of ensuring the assembly stability.

Referring to fig. 4, for example, the low-tone radiation mount 142 may be a mesh enclosure including a mesh enclosure surface 1421 and an annular mount 1422 connected to one side of the mesh enclosure surface 1421, the annular space formed by the annular mount 1422 may be used for placing the low-tone radiator 141 therein, the annular space formed by the annular mount 1422 may be in conformity with the edge shape of the low-tone radiator 141, and the outer side of the annular mount 1422 may be used for being clamped in the hole of the mounting hole 111.

Referring to fig. 4, a layer of mesh cloth 15 may be further covered on the outside of the enclosure 11 to achieve the effects of beauty, anti-slip, etc.

Referring to fig. 5 and 6, in the present embodiment, the microphone structure 20 may exemplarily include: a sound head 21, a sound head bracket 22 and a plastic decorative ring 23; wherein the sound head holder 22 includes a sound head setting portion 100, a vibration damping buffer portion 200, and a connecting portion 300 integrally connected, the sound head setting portion 100 includes a heightened side portion 101 and a receiving side portion 102 for receiving the sound head 21, the heightened side portion 101 is integrally connected with the receiving side portion 102; the included angle between the inner side wall of the heightened side portion 101 and the inner side wall of the accommodating side portion 102 is any one of 30 degrees to 70 degrees; the target cross section of the sound head setting portion 100 is a regular hexagon; the target section is perpendicular to the central axis (Z axis shown in fig. 6) of the sound head rest 22; the vibration damping buffer part 200 comprises at least one buffer ring 201, and the reference section of any buffer ring 201 in the at least one buffer ring 201 is an axisymmetric hexagon; the reference section is perpendicular to the target section; the sound head 21 is disposed in the sound head setting portion 100 of the sound head support 22, and the connecting portion 300 of the sound head support 22 is inserted into the plastic decorative ring 23.

In the microphone structure 20, the included angle between the inner side wall of the height-increasing side portion 101 and the inner side wall of the accommodating side portion 102 may be any angle from 30 degrees to 70 degrees, that is, the edge of the inner side wall of the sound head setting portion 100 may be open. Because there is a certain contained angle between the inside wall of the heightening side portion 101 and the inside wall of the accommodating side portion 102, the pick-up direction of the microphone structure 20 is the hypercardioid direction at this time, so that the possibility that the sound of the sound box structure 20 enters the sound head 21 from the right above the microphone after being reflected for many times is greatly reduced, thus, the positive feedback of the sound can be prevented, and the microphone structure 20 will not generate howling.

Meanwhile, since the average thickness of the regular hexagonal sound head setting part 100 is larger than that of the circular sound head setting part 100, when the sound head 21 is fixed to the regular hexagonal sound head setting part 100, the protection strength of the sound head 21 is greatly improved, so that the sound head 21 can be effectively protected when the microphone structure 20 falls down, and damage to the sound head 21 is avoided. In addition, the sound head setting portion 100 is made into a regular hexagon, so that the stress area can be increased when the sound head 21 is mounted, and the sound head support 22 can be screwed by a technician more conveniently.

Further, the vibration damping buffer 200 may include at least one buffer ring 201, and a reference section of any buffer ring 201 of the at least one buffer ring 201 may be an axisymmetric hexagon, wherein the reference section is perpendicular to the target section.

When a user uses the microphone and sound box integrated machine, the microphone and sound box integrated machine can shake along with the action of the user, at this time, the vibration reduction buffer part 200 can play a role in buffering, so that the shake amplitude of the sound head 21 can be reduced, and the sound head can be prevented from being separated from the sound head setting part 100 when the shake amplitude of the sound head 21 is overlarge. In addition, when the sound box structure 10 sounds, the sound head 21 can vibrate, so that the microphone structure 20 can also generate howling, and the vibration caused by the sound head 21 when the sound box structure 10 sounds can be weakened by the buffering action of the vibration damping buffer part 200, so that the microphone structure 20 can be further prevented from generating howling. Furthermore, since the axisymmetric hexagonal structure is more stable than the circular structure, the stability of the sound head 21 fixed by the sound head holder 22 can be improved accordingly.

Preferably, the reference cross section of any one buffer ring 201 of the at least one buffer ring 201 may be a regular hexagon.

It should be noted that, in practical applications, the number of the buffer rings 201 may be adaptively adjusted according to different microphone structures, referring to fig. 7, the damping buffer portion 200 may include two buffer rings 201, and of course, the damping buffer portion 200 may further include three buffer rings 201, four buffer rings 201, and so on, and the number of the buffer rings 201 is not specifically limited in this embodiment.

In this embodiment, the shore hardness of the sound head support 22 may be any hardness value between 35 degrees and 70 degrees, and the microphone structure 20 can be prevented from generating squeal to the greatest extent because the material with the shore hardness in the range of 35 degrees to 70 degrees has the strongest vibration-proof capability. In addition, the sound head support 22 may be made of any one of plastic, rubber and silica gel, that is, the sound head support 22 may be made of soft material.
