Description

Portable sound effect device and manufacturing method thereof

Technical Field

The invention relates to a combined microphone sound box, in particular to a portable sound effect device and a manufacturing method thereof. When the portable sound effect device is used, the howling problem is effectively solved, and the sound box of the portable sound effect device can turn in multiple directions relative to the microphone, so that the portable sound effect device can realize sound transmission in multiple directions without howling.

Background

The microphone and the loudspeaker box are a pair of acoustic devices that effect the reception and propagation of sound, both of which are typically used in a separate manner. The microphone may be used at a close distance from the speaker, which may cause a howling problem. Especially, for a microphone and a speaker with high sensitivity, howling is more likely to occur, so that they are usually used separately.

In addition, when using a microphone and a speaker, the orientation of the microphone and the orientation of the speaker are carefully considered. Once the orientation of any of the acoustic devices in the microphone and the speaker is problematic, not only is there a howling problem, but the use states of the microphone and the speaker also slip down. In a common use place, the sound box is fixed in orientation and rarely moves, which increases a plurality of limitations on the use mode of the microphone.

In order to make better use of a high-sensitivity, high-quality microphone and loudspeaker, one of the most straightforward approaches is to make the distance between the microphone and loudspeaker sufficiently large so that the microphone is located at a distance from the sound source in such a way that the attenuation of the picked-up sound is small. The conventional method for solving the howling problem is also a frequency equalization method, which compensates for the amplification curve by connecting a microphone and a speaker using an equalizer. In the occasion with high requirement on the sound quality, the traditional method also uses an audio feedback automatic suppression device to solve the problem of howling, the device can automatically track the frequency of a feedback point, automatically eliminate the sound feedback and protect the sound quality to the maximum extent, and the principle is to suppress the howling through a notch. However, the use of an equalizer or the like not only increases the cost but also causes a certain loss in sound transmission, and thus cannot be widely used.

In addition, in some temporary locations, because the sound boxes are not arranged in advance, in this case, if the sound boxes and the microphones are used, the sound boxes need to be arranged temporarily, and this way, there are many problems. For example, for persons without acoustic foundations, the task of arranging the loudspeaker boxes is a challenge, and if the loudspeaker boxes are not well arranged, the loudspeaker boxes not only do not play a role in amplifying sound, but also cause howling problems. In addition, the volume and the power of the existing mobile sound box are both large, and the existing mobile sound box is not suitable for temporary places with small space. Therefore, a microphone and a sound box are combined to form a portable sound effect device to meet the needs of the above-mentioned places. However, with the current technology, there are many problems to be solved if both the microphone and the audio box are used in combination. Also, with a portable sound effect apparatus in which a microphone and a box are combined, howling cannot be suppressed by changing the distance between the microphone and the box.

In order to combine the microphone and the sound box, the traditional scheme only uses a damping material at the joint of the microphone and the sound box to reduce vibration as much as possible, which results in unsatisfactory effect. The design of preventing howling mainly starts from three points: vibration damping for the microphone, vibration isolation for the connection portion, and vibration isolation for the speaker in the cabinet.

Furthermore, in the conventional combined microphone speaker, the speaker is directly fixed to the rear of the microphone for vibration isolation. The sound production direction of the sound box is opposite to the sound collection direction of the microphone. Then in use the microphone is normally facing upwards and the loudspeaker is facing downwards. Such a fixed orientation of the enclosure is very detrimental to sound transmission. In particular, in speech and the like, the cabinet needs to be oriented forward rather than on the ground. The conventional combined type microphone speaker cannot achieve such an effect.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

A portable audio device according to a first preferred embodiment of the present invention is described in the following description with reference to fig. 1. The portable sound effect device includes a sound box 10, a microphone 20 and a connecting mechanism 30, wherein the microphone 20 and the sound box 10 are connected to each other through the connecting mechanism 30, wherein the microphone 20 and the sound box 10 are electrically connected to each other, so that the sound box 10 can play the sound received by the microphone 20.

In other words, one end of the connection mechanism 30 is used to connect the speaker box 10, and the other end is used to connect the microphone 20, so that the connection mechanism 30 integrates the speaker box 10 and the microphone 20 to form the portable audio-effect device of the present invention. That is, when the audio effect apparatus of the present invention is used, the sound box 10 and the microphone 20 can be carried at the same time, so that when the portable audio effect apparatus is used in a temporary place, there is no need to additionally arrange a movable sound box, thereby facilitating use, and particularly, the portable audio effect apparatus is suitable for being applied to a temporary place having a small space.

It should be noted that at least one of the sound box 10, the microphone 20 and the connecting mechanism 30 in the preferred embodiment is designed to prevent howling. Preferably, the sound box 10, the microphone 20 and the connection mechanism 30 are designed to prevent howling, so that when the portable sound effect device is used, howling can be effectively prevented from being generated, thereby ensuring sound effects of the portable sound effect device. Meanwhile, the sound box 10 and the microphone 20 are both adapted to high-sensitivity acoustic devices to better represent sound.

Preferably, the connection mechanism 30 connects the tail end of the microphone 20 with the tail end of the sound box 10, so that the microphone 20 and the sound box 10 are integrated into a whole by the connection mechanism 30 to form the portable audio device of the present invention. In particular, the connecting mechanism 30 can be twisted to allow the speaker box 10 to rotate in different directions relative to the microphone 20, so that the speaker box 10 can have different orientations, thereby facilitating the adjustment of the angle during use.

In other words, the state of the connection mechanism 30 is adjustable, so that the sound box 10 can be adjusted in angle relative to the microphone 20, and the sound box 10 can be held in the adjusted position, so that when the portable audio-effect device is used, the sound box 10 can have different orientations, for example, when the portable audio-effect device is used, the microphone 20 is located near the mouth of the user, at which time the microphone 20 is tilted upward, and the orientation of the sound box 10 can be oriented forward after being adjusted, in such a way that the sound effect collected by the microphone 20 of the portable audio-effect device can be amplified by the sound box 10, and the amplified sound wave is radiated forward, so that the sound reproduced by the portable audio-effect device can be received by the listener located in front of the user, and the tone quality is better.

As shown in fig. 2 and 3, the microphone 20 of the portable sound effect device further includes a sound receiving device 21, a transmission circuit 22 and a microphone housing 23, wherein the sound receiving device 21 is disposed at one end of the microphone housing 23, the transmission circuit 22 is disposed inside the microphone housing 23, and the transmission circuit 22 communicatively connects the sound receiving device 21 and the sound box 10, so as to transmit the sound signal received by the sound receiving device 21 to the sound box 10 through the transmission circuit 22.

It is worth mentioning that the sound receiving device 21 is a sound wave collector capable of performing sound-electricity conversion after collecting the sound wave emitted by the user to convert the sound wave into an electric signal. Subsequently, the electrical signal can be transmitted and processed by the transmission circuit 22, for example, the transmission circuit 22 can perform, but is not limited to, noise reduction processing, amplification processing, and the like on the electrical signal. The transmission circuit 22 is then able to transmit electrical signals to the enclosure 10, and the enclosure 10, upon receiving and responding to the electrical signals, is able to perform electro-acoustic conversions to produce sound waves to reproduce sound effects.

It is also worth mentioning that the type of the sound receiving device 21 is not limited in the portable audio device of the present invention as long as it can collect the sound wave emitted from the user and perform the sound-electricity conversion of the sound wave. The type of the transmission circuit 22 is also not limited in the portable audio-effect device of the present invention as long as it can transmit electric signals. Preferably, the transmission circuit 22 is capable of performing, but not limited to, noise reduction processing, amplification processing, and the like on the electrical signal when transmitting the electrical signal.

Preferably, the connection mechanism 30 and the sound box 10 are sequentially disposed at the other end of the microphone housing 23, and then the transmission circuit 22 extends from the microphone 20 to the sound box 10 through the connection mechanism 30. It should be noted that, in the preferred embodiment, the sound receiving device 21 and the microphone housing 23 are fixed in a vibration isolation manner, and the possibility of howling is suppressed from the position of the sound receiving device 21. It is to be understood that the sound receiving device 21 converts sound from the form of sound waves into the form of electric signals, which in the present invention generally refers to signals in change and transmission. The sound receiving device 21 is preferably, but not limited to, a microphone.

In other words, one end of the connection mechanism 30 is connected to the sound box 10, and the other end is connected to the microphone case 23 of the microphone 20, so that the sound box 10 and the microphone 20 are integrated by the connection mechanism 30 to form the portable audio device of the present invention. The transmission circuit 22 of the microphone 20 can be electrically connected to the sound box 10 via the connection mechanism 30, so that the transmission circuit 22 can transmit the electrical signal generated by the sound collection device 21 to the sound box 10 to be subsequently converted into sound waves by the sound box 10 in response, thereby reproducing sound effects.

The loudspeaker 10 further comprises a loudspeaker housing 13, a main loudspeaker 11 arranged in the loudspeaker housing 13, a suspension mechanism 12 fixed between the loudspeaker housing 13 and the main loudspeaker 11, and a processing circuit 14 arranged inside the loudspeaker housing 13. In other words, the loudspeaker 10 includes the main horn 11, the suspension mechanism 12, the loudspeaker housing 13, and the processing circuit 14, wherein the main horn 11 is held inside the loudspeaker housing 13, one side of the suspension mechanism 12 is connected to the loudspeaker housing 13, and the other side is connected to the main horn 11, so that the suspension mechanism 12 can hold the main horn 11 inside the loudspeaker housing 13 in a suspended manner, and the processing circuit 14 can be electrically connected to the main horn 11 and the transmission circuit 22. The electrical signal transmitted by the transmission circuit 22 can be further transmitted to the main horn 11 by the processing circuit 14, so that the main horn 11 can receive and respond to the electrical signal to convert it into sound waves, thereby reproducing sound effects.

It is worth mentioning that in another example of the portable audio device of the present invention, the processing circuit 14 of the sound box 10 can be extended to the microphone housing 23 of the microphone 20 via the connection mechanism 30, and the processing circuit 14 can be electrically connected to the transmission circuit 22 inside the microphone housing 23.

The enclosure case 13 is connected to the microphone case 23 of the microphone 20 through the connection mechanism 30 to connect the enclosure 10 and the microphone 20, that is, one end of the connection mechanism 30 is provided to the microphone case 23 of the microphone 20 and the other end is provided to the enclosure case 13 of the enclosure 10, so that the enclosure 10 and the microphone 20 are integrated into one body by the connection mechanism 30 to form the portable audio device of the present invention. The processing circuit 14 is connected to the transmission circuit 22 and the main speaker 11, and the transmission circuit 22 transmits the electric signal to the main speaker 11, that is, the transmission circuit 22 can transmit the electric signal generated by the sound collection device 21 to the main speaker 11 via the processing circuit 14, and then the main speaker 11 can respond to the electric signal and convert the electric signal into sound wave after receiving the electric signal, thereby reproducing the sound effect. Preferably, the processing circuit 14 is disposed inside the speaker housing 13, and the processing circuit 14 does not contact the main speaker 11 except for signal transmission. That is, the processing circuit 14 is in signal connection with only the main horn 11, so that it is possible to prevent the vibration generated when the main horn 11 performs the electroacoustic conversion in response to the electric signal from acting on the processing circuit 14, and in this way, it is possible to further prevent the vibration generated when the main horn 11 performs the electroacoustic conversion in response to the electric signal from being sequentially transmitted to the sound receiving device 21 via the processing circuit 14 and the transmission circuit 22, thereby preventing the sound receiving device 21 from being interfered with, and suppressing howling.

It should be noted that, in the preferred embodiment, the main horn 11 is an integrated horn module, wherein the main horn 11 can be directly fixed to the suspension mechanism 12. As shown in fig. 3, the suspension mechanism 12 is disposed between the main horn 11 and the cabinet housing 13, so that the main horn 11 is held in the cabinet housing 13 in a suspended manner, and the suspension mechanism 12 serves to buffer the vibration of the main horn 11, thereby preventing the vibration of the main horn 11 generated during the electroacoustic conversion in response to the electric signal from acting on the cabinet housing 13. That is, when the main horn 11 performs electroacoustic conversion in response to an electric signal, the vibration of the main horn 11 is absorbed by the suspension mechanism 12 and is not transmitted to the cabinet case 13, which largely prevents the possibility of the portable sound effect device howling.

As shown in fig. 3, the main speaker 11 further includes a vibration portion 111, a voice coil 112, a magnetic return system 113, a frame 114 and a flexible suspension 115. The vibration part 111 is connected to the voice coil 112, and the vibration part 111 is provided to the frame 114 through the elastic suspension 115, but the vibration part 111 may be reciprocatingly vibrated by the traction of the voice coil 112 to generate sound. The magnetic return system 113 is disposed inside the frame 114, and the magnetic return system 113 is coupled to the voice coil 112.

In other words, the main horn 11 includes the vibrating portion 111, the voice coil 112, the magnetic loop system 113, the frame 114, and the elastic suspension 115, wherein the magnetic loop system 113 is disposed inside the frame 114, the magnetic loop system 113 is electrically connected to the processing circuit 14, the voice coil 112 is coupled to the magnetic loop system 113, the vibrating portion 111 is drivably connected to the voice coil 112, and the elastic suspension 115 extends inward and outward to be connected to the vibrating portion 111 and the frame 114, respectively. When the processing circuit 14 transmits an electrical signal to the magnetic loop system 113, the magnetic loop system 113 interacts with the voice coil 112 to drive the voice coil 112 to reciprocate, so that the voice coil 112 drives the vibration portion 111 to reciprocate, and meanwhile, the elastic suspension edge 115 is used for limiting the stroke of the reciprocating motion of the vibration portion 111 and preventing the vibration portion 111 from deflecting during the reciprocating motion, so that the vibration portion 111 generates sound waves by blowing air vibration, so that the main speaker 11 reproduces sound effects.

In addition, both sides of the suspension mechanism 12 are connected to the frame 114 of the main horn 11 and the cabinet case 13, respectively, so that the suspension mechanism 12 allows the main horn 11 to be held in suspension inside the cabinet case 13, in such a manner that, when the main horn 11 vibrates in the electro-acoustic conversion in response to an electric signal, the suspension mechanism 12 can absorb the vibration generated by the main horn 11 to prevent the vibration generated by the main horn 11 from acting on the cabinet case 13, thereby suppressing the portable sound effect device from howling.

Specifically, the suspension mechanism 12 includes a first suspension member 121 and a second suspension member 122, wherein the first suspension member 121 extends to both sides to be connected to the outer end of the frame 114 of the main horn 11 and the cabinet housing 13, respectively, and the second suspension member 122 extends to both sides to be connected to the inner end of the frame 114 of the main horn 11 and the cabinet housing 13, respectively, so that the first suspension member 121 and the second suspension member 122 serve to hold the main horn 11 inside the cabinet housing 13 in a suspended manner. It should be mentioned that the outer end and the inner end of the frame 114 correspond to each other, wherein the outer end of the frame 114 is close to the side of the main horn 11 where the vibration portion 111 is located, and the inner end of the frame 114 is far away from the side of the main horn 11 where the vibration portion 111 is located. Preferably, at least one of the first suspension member 121 and the second suspension member 122 is a unitary structure with the frame 114 of the main speaker 11 and the cabinet housing 13.

It should be noted that, the first hanging part 121 and the second hanging part 122 of the hanging mechanism 12 can ensure that the main speaker 11 does not shake left and right when vibrating and sounding in response to an electrical signal by hanging the main speaker 11 inside the speaker housing 13 at the outer end and the inner end of the speaker housing 13, respectively, thereby ensuring the purity of the sound effect generated by the main speaker 11. In addition, the first suspension member 121 and the second suspension member 122 can absorb the vibration generated by the main speaker 11, so that the first suspension member 121 and the second suspension member 122 can prevent the vibration generated by the main speaker 11 from acting on the cabinet housing 13, and further prevent the vibration generated by the main speaker 11 and the vibration generated by the sound collecting device 21 from interacting with each other, thereby preventing the occurrence of the undesirable phenomenon of squeal.

In fig. 4, the cross-section of the first hanging member 121 is in the shape of an inverted "U" and the cross-section of the second hanging member 122 is in the shape of a "U", in such a way that when the main horn 11 vibrates in response to an electrical signal, the first hanging member 121 and the second hanging member 122 can reduce or even avoid the displacement of the main horn 11 itself when absorbing the vibration generated by the main horn 11, thereby ensuring the purity of the sound effect generated by the main horn 11. Preferably, the first hanging part 121 and the second hanging part 122 are symmetrical to each other. However, it will be understood by those skilled in the art that, in other examples of the portable sound-effect device, the shape of the cross-section of the first suspension member 121 and the shape of the cross-section of the second suspension member 122 are both in an inverted "U" shape, or the shape of the cross-section of the first suspension member 121 and the shape of the cross-section of the second suspension member 122 are both in a "U" shape. It is worth mentioning that in some other examples of the portable sound-effect device of the present invention, the shape of the cross-section of the first suspension member 121 and the shape of the cross-section of the second suspension member 122 may be formed by other shapes, such as but not limited to wave shape.

Preferably, the first connection end 31 and the second connection end 32 are made of a material having vibration isolation, so as to isolate the vibration of the speaker box 10 and the vibration of the microphone 20 from each other, thereby preventing howling. Preferably, the first connection end 31 and the second connection end 32 are made of, but not limited to, rubber-like materials, so as to isolate the vibration of the sound box 10 and the vibration of the microphone 20 by the first connection end 31 and the second connection end 32 made of rubber-like materials. Preferably, the first connection end 31 may be disposed inside the enclosure case 13 of the enclosure 10, or the first connection end 31 may be disposed outside the enclosure case 13 of the enclosure 10, in such a way that the first connection end 31 can be connected to the enclosure case 13 of the enclosure 10. Accordingly, the second connection end portion 32 may be provided inside the microphone housing 23 of the microphone 20, or the second connection end portion 32 may be provided outside the microphone housing 23 of the microphone 20, for example, in this example of the portable audio device shown in fig. 2 and 3, a portion of the second connection end portion 32 is connected to the microphone housing 23 in such a manner as to fit over one end portion of the microphone housing 23 of the microphone 20.

Of course, it will be understood by those skilled in the art that in some examples of the portable audio device, only the first connection end 31 may be detachably connected to the enclosure housing 13 of the enclosure 10, or only the second connection end 32 may be detachably connected to the microphone housing 23 of the microphone 20.

It is to be noted that, in another example of the portable audio device of the present aspect, the first connection end 31 of the connection mechanism 30 may be integrally formed with the enclosure case 13 of the enclosure 10, and the second connection end 32 of the connection mechanism 30 may be integrally formed with the microphone case 23 of the microphone 20.

Further, one end of the connection housing 34 is mounted to the first connection end 31, and the other end is mounted to the second connection end 32, so that the connection housing 34 encloses the first connection end 31, the second connection end 32, and the steering shaft 33 therein to prevent the first connection end 31, the second connection end 32, and the steering shaft 33 from being exposed. Preferably, the connection housing 34 is implemented as, but not limited to, a corrugated tube to allow the connection housing 34 to be deformed and not damaged when the connection housing 34 is deformed.

In addition, in the preferred embodiment, the steering shaft 33 uses a steerable ball shaft, so that both ends of the steering shaft 33 connected thereto can be twisted relatively. That is, the first connecting end 31 and the second connecting end 32 can be relatively rotated to rotate the speaker 10 relative to the microphone 20, so as to adjust the direction of sound propagation more conveniently. As shown in fig. 7A to 7C, the sound box 10 is turned relative to the microphone 20, so as to play sound toward different directions. Fig. 7A shows the sound box 10 and the microphone 20 being coaxially disposed. Fig. 7B shows that the enclosure 10 can be twisted, if desired, to point to one side. Fig. 7B is different from fig. 7C in the steering angle. Of course, the sound box 10 can be twisted between different angles and can be stopped at any position therebetween. The flexible steering of the connection mechanism 30 allows the speaker box 10 to be oriented in a desired direction.

It is worth mentioning that the transmission circuit 22 is allowed to pass through or the processing circuit 14 is allowed to pass through in the connection housing 34. That is, the transmission circuit 22 extends from the sound receiving device 21 to the enclosure housing 13 of the enclosure 10 via the connection mechanism 30 and is electrically connected to the processing circuit 14 of the enclosure 10 inside the enclosure housing 13, as shown in fig. 5. Alternatively, the processing circuit 14 extends from the main loudspeaker 11 to the microphone housing 23 via the connection mechanism 30 and is electrically connected to the transmission circuit 22 inside the microphone housing 23. The loudspeaker 10 may receive an electrical signal directly from the microphone 20.

Preferably, the sound box 10 can also work independently as an independent playing source, i.e., the sound box 10 can be used independently. Specifically, the processing circuit 14 further includes a processing module 141, a communication module 142, and a power supply module 143, wherein the processing module 141 and the communication module 142 are communicatively connected to each other, and the power supply module 143 supplies power to the processing module 141 and the main speaker 11. The communication module 142 is connected to the transmission circuit 22 to receive the electrical signal from the transmission circuit 22, wherein the processing module 141 processes the electrical signal received by the communication module 142, the processing module 141 is communicably interconnected with the main speaker 11 to transmit the processed electrical signal to the main speaker 11, and the main speaker 11 can reproduce sound effects in response to the electrical signal after receiving the electrical signal.

When the microphone 20 is used as a sound source, the sound receiving device 21 converts the collected sound into an electrical signal, and the electrical signal is transmitted to the processing module 141 of the processing circuit 14 by the transmission circuit 22. The processing module 141 processes the electrical signal and transmits the processed electrical signal to the main speaker 11, and the main speaker 11 can reproduce a sound effect in response to the electrical signal after receiving the electrical signal. When using external signal as the sound source, communication module 142 receives the electric signal that needs to be played, processing module 141 handles the electric signal and reaches main loudspeaker 11, main loudspeaker 11 can respond to the electric signal and reappear the sound effect after receiving the electric signal. Preferably, the communication module 142 is, but not limited to, a bluetooth communication module, and the power supply module 143 is, but not limited to, a lithium battery.

When the portable sound effect device is used, the vibration generated by the sound receiving device 21 is isolated by the microphone housing 23, for example, a pad body for absorbing vibration, such as but not limited to a rubber pad, a silicone pad, etc., may be disposed between the sound receiving device 21 and the microphone device 21 to isolate the vibration generated by the sound receiving device 21, so as to prevent the vibration generated by the sound receiving device 21 from being transmitted to the microphone housing 23. And the sound received by the sound receiving device 21 is converted into an electric signal. The transmission circuit 22 transmits the electrical signal to the sound box 10. And the connection mechanism 30 at the connection of the microphone 20 and the sound box 10 isolates the vibration of the microphone 20 and the sound box 10 from each other. Specifically, the second connection end 32 connected to the microphone case 23 and the first connection end 31 connected to the speaker case 13 are made of a material having vibration isolation, so that the microphone 20 is isolated from the vibration of the speaker 10. But the electrical signal is still transmitted to the processing circuit 14 of the loudspeaker enclosure 10 via the transmission circuit 22. The processing circuit 14 transmits an electrical signal to the main horn 11. The main horn 11 is able to reproduce sound effects in response to electrical signals, in the course of which the main horn 11 of course also generates vibrations. The suspension mechanism 12 does not transmit the vibration generated by the main horn 11 to the cabinet housing 13. Specifically, the first suspension member 121 and the second suspension member 122 of the suspension mechanism 12 not only can absorb the vibration generated by the main speaker 11 to prevent the vibration from being conducted to the cabinet housing 13, but also the first suspension member 121 and the second suspension member 122 can enhance the bass sound effect of the main speaker 11 by keeping the main speaker 11 suspended, thereby improving the sound quality of the main speaker 11.

Since the main horn 11 resonates with the cabinet housing 13 when vibrating, the cabinet housing 13 is preferably made of a material that absorbs vibration. In the preferred embodiment, a PP material, a foamed material, a wooden material, or the like is preferred. In addition, in order to better isolate the vibration of the speaker 10 and the microphone 20, the first connection end 31 and the second connection end 32 are preferably made of a vibration isolation rubber material. In this way, vibration is effectively isolated among the sound receiving device 21, the connecting mechanism 30, and the suspending mechanism 12, and thus, the occurrence of a trouble such as squeal in the portable audio device is effectively prevented.

In addition, in the preferred embodiment, the steering shaft 33 uses a steerable ball shaft, so that both ends of the steering shaft 33 connected thereto can be twisted relatively. Of course, in order to allow the two ends of the steering shaft 33 to be connected to be twisted relatively, the first connecting end portion 31 and the second connecting end portion 32 may be twisted relatively, and the steering shaft 33 may be an elastic coupling shaft, a bendable coupling shaft, a snap hinge, or the like. It is worth mentioning that the connecting housing 34 is of a steerable design in order to match the steering of the steering shaft 33. Preferably, the connection housing 34 is formed by wrapping the first connection end 31, the second connection end 32 and the steering shaft 33 with a bellows. So that the connecting housing 34 can also be steered with the steering shaft 33.

It is worth mentioning that the sound box 10 may not use the microphone 20 as a sound source. That is, the enclosure 10 may receive and respond to external electrical signals for use as a stand-alone enclosure. Preferably, the communication module 142 is a bluetooth communication module, but a wireless network, a wired network, and the like may also be used. When using external electric signal as sound source, communication module 142 receives the electric signal, processing module 141 handles the electric signal and reaches main loudspeaker 11, main loudspeaker 11 can respond to the electric signal and reappear the sound effect after receiving the electric signal. The suspension mechanism 12 isolates the vibration of the main horn 11 so that the cabinet housing 13 is not affected by the vibration.

Fig. 8A and 8B show a state of the main horn 11 of the sound box 10 when vibrating and generating sound in response to an input of an electrical signal, when the main horn 11 vibrates the vibrating portion 111 to the outside in response to the input of the electrical signal, the vibration of the vibrating portion 111 drives the whole main horn 11 to have a tendency of generating displacement to the outside, and at this time, the first hanging member 121 and the second hanging member 122 of the hanging mechanism 12 are used for limiting the displacement of the main horn 11 to the outside. Accordingly, when the main horn 11 vibrates the vibrating portion 111 inwardly in response to the input of the electrical signal, the vibration of the vibrating portion 111 drives the whole main horn 11 to have a tendency of displacement toward the inner side, and at this time, the first hanging member 121 and the second hanging member 122 of the hanging mechanism 12 are used for limiting the displacement of the main horn 11 toward the outer side. In this way, on the one hand, the first suspension member 121 and the second suspension member 122 can prevent the main horn 11 from shaking inside the cabinet housing 13, and on the other hand, the first suspension member 121 and the second suspension member 122 can absorb the vibration generated by the main horn 11 to prevent the vibration from acting on the cabinet housing 13, thereby preventing the vibration from adversely affecting the microphone 20.

Preferably, the connecting mechanism 30 connects the tail end of the microphone 20 with the tail end of the sound box 10. In particular, the connecting mechanism 30 is rotatable to allow the speaker box 10 to rotate in different directions relative to the microphone 20, so that the speaker box 10 can have different orientations, thereby facilitating the adjustment of the angle during use. It should be noted that the sound box 10, the microphone 20 and the connecting mechanism 30 in the preferred embodiment all adopt anti-howling designs, so as to effectively prevent the occurrence of howling during use. Meanwhile, the sound box 10 and the microphone 20 are both suitable for high-sensitivity acoustic equipment, so that sound can be better displayed.

Here, the suspension mechanism 12 is fixed between the main horn 11 and the cabinet housing 13, and serves to buffer the vibration of the main horn 11 and enhance the bass audio of the main horn 11. Then, when the main horn 11 is in use, the vibration of the main horn 11 is absorbed by the suspension mechanism 12 and is not transmitted to the enclosure 13. This greatly attenuates the possibility of howling. In addition, the suspension mechanism 12 further includes a first suspension member 121, wherein the first suspension member 121 is connected to the main horn 11 and the cabinet housing 13, so that the first suspension member 121 holds the main horn 11 in a suspended manner inside the cabinet housing 13, and when the main horn 11 vibrates, on one hand, the first suspension member 121 can absorb the vibration of the main horn 11, and on the other hand, the first suspension member 121 can prevent the main horn 11 from shaking when vibrating, thereby ensuring the purity of the sound effect generated by the main horn 11. Preferably, the first suspension member 121 protrudes outward of the cabinet housing 13.

As shown in fig. 13 and 14, the suspension mechanism 12 is located between the main horn 11 and the cabinet housing 13, and serves to buffer the vibration of the main horn 11. In other words, the suspension mechanism 12 held between the main horn 11 and the cabinet housing 13 is configured to hold the main horn 11 inside the cabinet housing 13, absorb vibration generated by the main horn 11 to prevent the vibration from acting on the cabinet housing 13, and enhance the low-frequency sound effect of the main horn 11. That is, when the main horn 11 vibrates and generates sound, the vibration of the main horn 11 is absorbed by the suspension mechanism 12 and is not transmitted to the cabinet case 13. This greatly attenuates the possibility of howling.

As shown in fig. 13 and 14, the main horn 11 includes a vibrating portion 111, a voice coil 112, a magnetic loop system 113, a frame 114, and an elastic suspension 115, wherein the magnetic loop system 113 is disposed inside the frame 114, the magnetic loop system 113 is electrically connected to the processing circuit 14, the voice coil 112 is coupled to the magnetic loop system 113, the vibrating portion 111 is drivably connected to the voice coil 112, and the elastic suspension 115 extends inward and outward to connect the vibrating portion 111 and the frame 114, respectively. When the processing circuit 14 transmits an electrical signal to the magnetic loop system 113, the magnetic loop system 113 interacts with the voice coil 112 to drive the voice coil 112 to reciprocate, so that the voice coil 112 drives the vibration portion 111 to reciprocate, and meanwhile, the elastic suspension edge 115 is used for limiting the stroke of the reciprocating motion of the vibration portion 111 and preventing the vibration portion 111 from deflecting during the reciprocating motion, so that the vibration portion 111 generates sound waves by blowing air vibration, so that the main speaker 11 reproduces sound effects.

In addition, the suspension mechanism 12 further includes a first suspension member 121 and a second suspension member 122, wherein both sides of the first suspension member 121 are connected to the frame 114 and the cabinet housing 13 of the main speaker 11, respectively, and both sides of the second suspension member 122 are connected between the housing of the magnetic loop system 113 of the main speaker 11 and the cabinet housing 13, respectively, so that the first suspension member 121 and the second suspension member 122 can cooperate with each other to keep the main speaker 11 suspended inside the cabinet housing 13, and when the main speaker 11 vibrates to generate sound, the first suspension member 121 and the second suspension member 122 can prevent the main speaker 11 from vibrating, thereby making the sound generated by the main speaker 11 more pure to ensure the sound effect of the portable sound-effect apparatus.

Further, the first connection end 31 and the second connection end 32 are made of a material having vibration isolation, and isolate the vibration of the speaker 10 and the vibration of the microphone 20 from each other, thereby preventing howling. Preferably, the first connection end 31 and the second connection end 32 partially wrap the speaker housing 13 and the microphone housing 23 with a rubber-like material to isolate vibrations from each other. In addition, in the preferred embodiment, the steering shaft 33 is a steerable shaft, and both ends of the steering shaft 33 connected to each other can be twisted relatively. That is, the first connecting end 31 and the second connecting end 32 can be relatively rotated to rotate the speaker 10 relative to the microphone 20, so as to adjust the direction of sound propagation more conveniently.

It is worth mentioning that the transmission circuit 22 is allowed to pass through the steering shaft 33. That is, the transmission circuit 22 extends from the sound receiving device 21 to the connection mechanism 30 to the processing circuit 14 of the sound box 10.

When the microphone 20 is used as a sound source, the sound receiving device 21 converts the collected sound into an electrical signal, and the electrical signal is transmitted to the processing module 141 of the processing circuit 14 by the transmission circuit 22. The processing module 141 processes the electrical signal and transmits the processed electrical signal to the main speaker 11. When an external electric signal is used as a sound source, the communication module 142 receives the electric signal, and the processing module 141 processes the electric signal and transmits the electric signal to the main speaker 11 for playing. Preferably, the communication module 142 is, but not limited to, a bluetooth communication module, and the power supply module 143 is, but not limited to, a lithium battery.

When the portable audio device is in use, vibrations generated by the sound receiving device 21 are isolated by the microphone housing 23. And the sound received by the sound receiving device 21 is converted into an electric signal. The transmission circuit 22 transmits the electrical signal to the sound box 10. And the connection mechanism 30 at the connection of the microphone 20 and the sound box 10 isolates the vibration of the microphone 20 and the sound box 10 from each other. Specifically, the second connection end 32 connected to the microphone case 23 and the first connection end 31 connected to the speaker case 13 are made of vibration-proof materials. Thus, the microphone 20 is isolated from the vibrations of the enclosure 10. But the electrical signal is still transmitted to the processing circuit 14 of the loudspeaker enclosure 10 via the transmission circuit 22. The processing circuit 14 transmits an electrical signal to the main horn 11. The main horn 11 sounds in response to the electrical signal, although the main horn 11 also vibrates. The suspension mechanism 12 absorbs the vibration generated by the main horn 11 so that the vibration is not transmitted to the cabinet housing 13.
