Abstract
The invention discloses a sound effect device, a manufacturing method thereof and a sound production method, wherein the sound effect device comprises at least two loudspeakers, wherein the central axis of at least one loudspeaker deviates from the central axis of the other loudspeaker, so that the problem that sound waves generated by the loudspeakers are mutually offset after meeting can be avoided, and the sound effect of a full sound field is realized.
Description
Technical Field
The invention relates to sound production equipment, in particular to a sound effect device and a manufacturing method and a sound production method thereof.
Background
A speaker is a common electro-acoustic conversion device, and when the speaker responds to an input of an audio signal, a drum paper of the speaker can vibrate back and forth to blow air to generate sound waves. As is known from the sound emission principle of a speaker, the speaker has a sound emission characteristic of high directivity, and therefore, when the speaker is applied to a room, for example, a conference room, it is usually installed obliquely at a corner position of the top of the room, and the drum paper of the speaker is directed obliquely downward toward the center of the room, so that the sound wave generated by the speaker may be spread over a large area of the room. Obviously, on the one hand, the flexibility of the installation position of the loudspeaker is greatly limited; on the other hand, the speaker is hung at the corner of the top of the room, so that the speaker has a falling risk and the safety is affected, and especially for the bass speaker, the vibration of the speaker causes the loosening of the fixing bolt and the potential safety hazard is caused; on the other hand, the way speakers are installed at the corners of the top of a room affects the beauty of the room.
In addition, it is generally difficult for one speaker to generate sound waves in the whole-tone frequency band, for example, a high pitch speaker is generally used to generate high frequency sound waves, a medium pitch speaker is generally used to generate medium and high frequency sound waves, a medium and low pitch speaker is generally used to generate medium and low frequency sound waves, and a listener needs to combine two or more speakers according to acoustic knowledge if listening to sound waves in the whole-tone frequency band. But for the vast majority of listeners, it does not have professional acoustic knowledge, which results in: when a listener combines more than two speakers, sound waves generated by the speakers can be mutually offset after meeting, so that the combined speaker combination cannot generate sound effects expected by the listener.

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.
In accordance with the present invention, an audio device according to a preferred embodiment of the present invention is disclosed and illustrated in the following description, wherein said audio device comprises at least two loudspeakers 10, said loudspeakers 10 being capable of combining with each other to produce full sound field audio effects, according to the accompanying drawings of fig. 1 to 3.
For example, in the specific example of the sound effect device shown in fig. 1 to 3, the sound effect device includes two speakers 10, wherein one speaker 10 is a tweeter 10a and the other speaker 10 is a midrange speaker 10b, so that when an audio signal is inputted into the sound effect device, the tweeter 10a and the midrange speaker 10b can cooperate with each other to cause the sound effect device to produce a sound effect of a full-audio frequency band.
Preferably, the orientation of the tweeter diaphragm 11a of the tweeter 10a is the same as the orientation of the midbass diaphragm 11b of the midbass loudspeaker 10b, and the tweeter 10a is maintained in the sound wave radiation direction of the midbass loudspeaker 10b, so that the tweeter 10a can reflect the sound waves generated by the midbass loudspeaker 10b in all directions, so that the listeners around the sound effect device can all listen to a better sound effect. That is, for the sound effect device of the present invention, even if the tweeter 11a of the tweeter 10a and the midbass diaphragm 11b of the midbass speaker 10b are not directed toward the listener but the listener is located around the sound effect device, the sound waves generated by the midbass speaker 10b can be reflected by the tweeter 10a in all directions, so that the listener located around the sound effect device can receive a better sound effect.
More preferably, referring to fig. 3, the central axis of the tweeter 10a and the central axis of the midbass speaker 10b are spaced apart from each other, that is, the central axis of the tweeter 10a is offset from the central axis of the midbass speaker 10b, so that when the tweeter 10a and the midbass speaker 10b generate sound waves in response to the input of audio signals, respectively, the sound waves generated by the tweeter 10a and the midbass speaker 10b do not cancel each other after meeting each other, thereby generating the sound effect of a full sound field.
In other words, in the sound effect device of the present invention, the central axis of the tweeter 10a and the central axis of the midbass speaker 10b do not coincide with each other, but the central axis of the tweeter 10a is deviated from the central axis of the midbass speaker 10b, so that the tweeter 10a and the midbass speaker 10b are displaced from each other, thereby preventing the sound waves generated by the tweeter 10a and the midbass speaker 10b from canceling each other after meeting each other, and enabling the sound effect device to generate the sound effect of the full sound field.
With continued reference to fig. 1 to 3, the audio device further includes a supporting unit 20, wherein the supporting unit 20 includes a holding portion 21, at least one cantilever 22 and a supporting portion 23, and two ends of the cantilever 22 respectively extend to be connected to the holding portion 21 and the supporting portion 23.
It should be noted that the manner in which the end of the cantilever 22 is connected to the holding portion 21 and the supporting portion 23 is not limited in the audio device of the present invention, and for example, one end of the cantilever 22 may be attached to the holding portion 21 or integrally extended from the holding portion 21, and the other end of the cantilever 22 may be attached to the supporting portion 23 or integrally extended from the supporting portion 23.
The holding portion 21 of the holder unit 20 is mounted to the midbass frame 12b of the midbass speaker 10b, the holding portion 23 of the holder unit 20 is mounted to the treble frame 12a of the treble speaker 10a, and the cantilever 22 of the holder unit 20 causes the treble speaker 10a to be held in the sound wave radiation direction of the midbass speaker 10b, so that the treble speaker 10a can reflect the sound waves generated by the midbass speaker 10b in all directions. Preferably, a surface of the treble frame 12a of the tweeter 10a facing the midbass diaphragm 11b of the midbass speaker 10b forms a spherical surface, so that the tweeter 10a can uniformly reflect sound waves generated from the midbass speaker 10b in all directions.
Unlike the sound effect device shown in fig. 1 to 3, in an alternative example of the sound effect device shown in fig. 4 to 6, the surface of the receiver 23 of the holder unit 20 facing the midbass diaphragm 11b of the midbass speaker 10b forms a spherical surface, and the spherical surface is disposed facing the midbass diaphragm 11b of the midbass speaker 10b, so that the spherical surface of the receiver 23 can uniformly reflect sound waves generated by the midbass speaker 10b in all directions. That is, in this specific example of the sound effect device shown in fig. 4 to 6, the tweeter frame 12a of the tweeter 10a is not directly directed toward the diaphragm of the midbass speaker 10b and is not used to reflect the sound wave generated by the midbass speaker 10b, but the tweeter frame 12a of the tweeter 10a is hidden inside the retainer 23 of the retainer unit 20 to allow the spherical surface of the retainer 23 to be directly directed toward the diaphragm of the midbass speaker 10a, thus allowing the spherical surface of the retainer 23 to uniformly reflect the sound wave generated by the midbass speaker 10b in all directions.
Alternatively, in further examples, the support 20 of the support unit 20 forms the tweeter frame 12a of the tweeter 10 a.

In addition, the suspension arm 22 has a strong rigidity, so that when the sound waves generated by the mid-woofer 10b are radiated to the tweeter 10a and reflected by the tweeter 10a, the tweeter 10a is prevented from shaking or the amplitude of the shaking of the tweeter 10a is allowed to be kept within a reasonable range, so that noise waves are prevented as much as possible from causing sound wave pollution.
With continued reference to fig. 1-3, the sound effect device further includes a sound wave reflector 30, wherein the sound wave reflector 30 is maintained in the sound wave radiation direction of the tweeter 10a for reflecting the sound waves generated by the tweeter 10a in all directions, so that the listener can hear better sound effects all around the sound effect device. Preferably, a surface of the sound wave reflector 30 facing the tweeter 11a of the tweeter 10a forms a reflective spherical surface 31 to allow the reflective spherical surface 31 of the sound wave reflector 30 to uniformly reflect the sound waves generated from the tweeter 10a in all directions. Preferably, the center axis of the tweeter 10a passes through the center of the reflective spherical surface 31 of the acoustic reflector 30.
Further, the sound effect device includes a reflector holding unit 40, the sound wave reflector 30 is provided to the reflector holding unit 40, and the reflector holding unit 40 is mounted to the tweeter frame 12a of the tweeter 10a such that the reflector holding unit 40 can hold the sound wave reflector 30 in the sound wave radiating direction of the tweeter 10 a.
It is to be noted that the manner in which the acoustic wave reflector 30 is provided to the reflector holding unit 40 is not limited, and for example, both may be integrally formed or may be separately formed and then attached to each other.
According to another aspect of the present invention, there is also provided a manufacturing method of the sound effect device, wherein in the manufacturing method, first, the tweeter 10a and the midbass speaker 10b are provided; secondly, the sound effect device is manufactured in such a manner that the center axis of the tweeter 10a is offset from the center axis of the midbass speaker 10b to allow the tweeter 10a to be maintained in the sound wave radiation direction of the midbass speaker 10 b.
Preferably, in the manufacturing method, the tweeter 10a is allowed to be held in the sound wave radiation direction of the midbass speaker 10b by one of the holder units 20.
For example, in a preferred example of the manufacturing method of the present invention, first, the holding portion 21 of the holder unit 20 is mounted on the midbass frame 12b of the midbass speaker 10 b; next, the tweeter 10a is mounted on the support portion 23 of the holder unit 20 so that the tweeter 10b is allowed to maintain the sound wave radiation direction of the midbass speaker 10 b. Also in this preferred example, the surface of the tweeter 10a facing the midbass diaphragm 11b of the midbass speaker 10b may be formed into a spherical surface so as to allow the spherical surface of the tweeter 10a to reflect the sound waves generated by the midbass speaker 10b, or the surface of the receiver 23 of the holder unit 20 facing the midbass diaphragm 11b of the midbass speaker 10b and the receiver 23 facing the midbass diaphragm 11b of the midbass speaker 10b may be formed into a spherical surface so as to allow the spherical surface of the receiver 23 to reflect the sound waves generated by the midbass speaker 10b is hidden in the receiver 23.
