Abstract
The invention discloses an audio device, a manufacturing method thereof and a sounding method thereof, wherein the audio 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 counteracted after meeting can be avoided, and full-sound-field audio is realized.
Description
Technical Field
The present invention relates to sound emitting devices, and more particularly, to a sound effect device, a method of manufacturing the sound effect device, and a sound emitting method.
Background
A speaker is a common electroacoustic transducer device, and when the speaker responds to input of an audio signal, a paper drum of the speaker can vibrate back and forth to excite air to generate sound waves. It is known based on the sound emission principle of a speaker that the speaker has a sound emission characteristic with strong directivity, so that when the speaker is applied to a room, for example, when the speaker is applied to a room as a conference room, it is generally installed obliquely at a corner position of the top of the room with the paper of the speaker obliquely downward toward the middle of the room, so that sound waves generated by the speaker may be spread to a large area of the room. Obviously, on the one hand, the flexibility of the installation position of the speaker is greatly limited; on the other hand, the mode of hanging the loudspeaker at the corner of the top of the room can cause the risk of falling off of the loudspeaker to influence the safety, and particularly for a bass loudspeaker, the vibration of the loudspeaker can cause loosening of a fixing bolt to cause potential safety hazards; in yet another aspect, the manner in which speakers are mounted in the corners of the top of a room can affect the aesthetics of the room.
In addition, it is often difficult for one speaker to generate sound waves of the full-range, for example, a tweeter is often used to generate sound waves of high frequency, a mid-tweeter is often used to generate sound waves of medium-high frequency, a mid-woofer is often used to generate sound waves of medium-low frequency, and a woofer is often used to generate sound waves of low frequency, and if a listener is to listen to sound waves of the full-range, it is necessary to combine two or more speakers according to acoustic knowledge. But for the vast majority of listeners it does not have expert acoustic knowledge, which leads to the result that: when a listener combines more than two speakers, the sound waves generated by the speakers will cancel each other after meeting, so that the combined speakers cannot produce the sound effect desired by the listener.

It will be understood that the terms "a" and "an" should be interpreted as referring to "at least one" or "one or more," i.e., in one embodiment, the number of elements may be one, while in another embodiment, the number of elements may be plural, and the term "a" should not be interpreted as limiting the number.
In the following description, an audio device according to a preferred embodiment of the present invention is disclosed and described with reference to fig. 1 to 3 of the drawings, wherein the audio device comprises at least two speakers 10, and the speakers 10 can be combined with each other to generate full-sound effects.
For example, in this specific example of the audio device shown in fig. 1 to 3, the audio device includes two speakers 10, wherein one speaker 10 is a tweeter 10a and the other speaker 10 is a mid-bass speaker 10b, so that when an audio signal is input to the audio device, the tweeter 10a and the mid-bass speaker 10b can cooperate with each other to cause the audio device to produce full-audio.
Preferably, the orientation of the tweeter 11a of the tweeter 10a is the same as the orientation of the mid-bass diaphragm 11b of the mid-bass speaker 10b, and the tweeter 10a is held in the direction of sound wave radiation of the mid-bass speaker 10b, so that the tweeter 10a can reflect sound waves generated by the mid-bass speaker 10b in all directions, and a listener located around the sound effect device can hear a better sound effect. That is, in the sound effect device of the present invention, even if the tweeter diaphragm 11a of the tweeter 10a and the mid-woofer diaphragm 11b of the mid-woofer 10b are not directed toward the listener, but the listener is located around the sound effect device, since the tweeter 10a can reflect sound waves generated by the mid-woofer 10b in all directions, the listener located around the sound effect device can listen to a preferable sound effect.
More preferably, referring to fig. 3, the center axis of the tweeter 10a and the center axis of the mid-woofer 10b have a distance therebetween, that is, the center axis of the tweeter 10a is offset from the center axis of the mid-woofer 10b, such that when the tweeter 10a and the mid-woofer 10b generate sound waves in response to input of audio signals, respectively, the sound waves generated by the tweeter 10a and the sound waves generated by the mid-woofer 10b do not cancel each other after meeting, thereby generating full-sound effects.
In other words, in the sound effect device of the present invention, the center axis of the tweeter 10a and the center axis of the mid-woofer 10b do not coincide, but the center axis of the tweeter 10a is offset from the center axis of the mid-woofer 10b so that the tweeter 10a and the mid-woofer 10b are offset from each other, and thus, the sound waves generated by the tweeter 10a and the sound waves generated by the mid-woofer 10b are prevented from canceling each other after meeting, thereby enabling the sound effect device to generate the sound effect of the full sound field.
With continued reference to fig. 1-3, 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 both ends of the cantilever 22 are respectively extended to be connected to the holding portion 21 and the supporting portion 23.
It should be noted that the manner in which the end portion of the cantilever 22 is connected to the holding portion 21 and the receiving portion 23 is not limited in the audio device of the present invention, for example, one end portion of the cantilever 22 may be mounted to the holding portion 21 or integrally extended to the holding portion 21, and the other end portion of the cantilever 22 may be mounted to the receiving portion 23 or integrally extended to the receiving portion 23.
The holding portion 21 of the supporting unit 20 is mounted to the mid-bass frame 12b of the mid-bass speaker 10b, the supporting portion 23 of the supporting unit 20 is mounted to the tweeter frame 12a of the tweeter 10a, and the cantilever 22 of the supporting unit 20 causes the tweeter 10a to be held in the sound wave radiation direction of the mid-bass speaker 10b, so that the tweeter 10a can reflect sound waves generated by the mid-bass speaker 10b in all directions. Preferably, the surface of the tweeter frame 12a of the tweeter 10a facing the mid-bass diaphragm 11b of the mid-bass speaker 10b is formed into a spherical surface, so that the tweeter 10a can uniformly reflect sound waves generated by the mid-bass speaker 10b in all directions.
Unlike the acoustic device shown in fig. 1 to 3, in an alternative example of the acoustic device shown in fig. 4 to 6, the surface of the support portion 23 of the support unit 20 facing the mid-bass diaphragm 11b of the mid-bass speaker 10b forms a spherical surface, and the spherical surface is disposed facing the mid-bass diaphragm 11b of the mid-bass speaker 10b such that the spherical surface of the support portion 23 can uniformly reflect sound waves generated by the mid-bass 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 mid-woofer 10b and is not used to reflect the sound waves generated by the mid-woofer 10b, but the tweeter frame 12a of the tweeter 10a is hidden inside the support portion 23 of the support unit 20 to allow the spherical surface of the support portion 23 to be directly directed toward the diaphragm of the mid-woofer 10a, thus allowing the spherical surface of the support portion 23 to uniformly reflect the sound waves generated by the mid-woofer 10b in all directions.
Alternatively, in another example, the support part 20 of the support unit 20 forms the tweeter frame 12a of the tweeter 10 a.
With continued reference to fig. 1 to 3, the holding portion 21 of the support unit 20 is in a ring shape, and may be mounted on the mid-bass frame 12b of the mid-bass speaker 10b by means of glue, screws, etc., and the holding portion 21 surrounds the periphery of the mid-bass diaphragm 11b of the mid-bass speaker 10 b.
The number of cantilevers 22 of the support unit 20 is preferably one, and the width dimension of the cantilevers 22 is maintained in a reasonable range to avoid sound wave contamination by sound waves reflected by the cantilevers 22 as much as possible. In addition, the cantilever 22 has a strong rigidity, so that when the sound wave generated by the mid-bass speaker 10b is radiated to the tweeter 10a and reflected by the tweeter 10a, the jolt of the tweeter 10a can be avoided or the jolt amplitude of the tweeter 10a is allowed to be kept within a reasonable range, so that the sound wave pollution caused by the noise wave is avoided as much as possible.
With continued reference to fig. 1-3, the audio device further includes an acoustic reflector 30, wherein the acoustic reflector 30 is maintained in the direction of the acoustic radiation of the tweeter 10a for reflecting the acoustic waves generated by the tweeter 10a in all directions, so that a listener can hear a better audio effect around the audio device. Preferably, a reflection spherical surface 31 is formed on a surface of the sound wave reflector 30 facing the tweeter diaphragm 11a of the tweeter 10a, so as to allow the reflection spherical surface 31 of the sound wave reflector 30 to uniformly reflect sound waves generated by the tweeter 10a in all directions. Preferably, the center axis of the tweeter 10a passes through the center of the reflecting spherical surface 31 of the acoustic wave reflector 30.
Further, the sound effect device includes a reflector holding unit 40, the sound wave reflector 30 is disposed on the reflector holding unit 40, and the reflector holding unit 40 is mounted on the tweeter frame 12a of the tweeter 10a, so that the reflector holding unit 40 can hold the sound wave reflector 30 in the sound wave radiation direction of the tweeter 10 a.
It should be noted that the manner in which the acoustic wave reflector 30 is disposed in the reflector holding unit 40 is not limited, and for example, both may be integrally formed or 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 mid-bass speaker 10b are provided; next, 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 mid-woofer 10b, allowing the tweeter 10a to remain in the direction of sound wave radiation of the mid-woofer 10 b.
Preferably, in the manufacturing method, the tweeter 10a is allowed to maintain the sound wave radiation direction of the mid-bass speaker 10b by one of the support units 20.
For example, in a preferred example of the manufacturing method of the present invention, first, the holding portion 21 of the cradle unit 20 is mounted to the mid-bass frame 12b of the mid-bass speaker 10b; next, the tweeter 10a is mounted to the support portion 23 of the support unit 20, so that the tweeter 10b is allowed to maintain the sound wave radiation direction of the mid-woofer 10 b. And in this preferred example, the surface of the tweeter 10a facing the mid-bass diaphragm 11b of the mid-bass speaker 10b may be formed into a spherical surface, thus allowing the spherical surface of the tweeter 10a to reflect sound waves generated by the mid-bass speaker 10b, or the surfaces of the support 23 facing the mid-bass diaphragm 11b of the mid-bass speaker 10b and the support 23 facing the mid-bass diaphragm 11b of the mid-bass speaker 10b may be formed into a spherical surface, and the tweeter frame 12a of the tweeter 10a is hidden at the support 23, thus allowing the spherical surface of the support 23 to reflect sound waves generated by the mid-bass speaker 10 b.
Alternatively, in another preferred example of the manufacturing method of the present invention, the supporting part 23 of the supporting unit 20 forms the tweeter frame 12a of the tweeter 10a, i.e., the supporting part 23 and the tweeter frame 12a are of a unitary structure.
According to another aspect of the present invention, there is further provided a sounding method, wherein the sounding method includes the steps of:
(a) At least two speakers 10 allowing the center axes to deviate simultaneously generate sound waves in response to input of an audio signal; and
(b) Sound waves generated by these speakers 10 are prevented from canceling after meeting to produce full sound effects.
In a preferred example of the sound producing method of the present invention, the diaphragms 11 of the speakers 10 are oriented identically. For example, in the audio device shown in fig. 1 to 3, the orientation of the tweeter diaphragm 11a of the tweeter 10a is the same as the orientation of the mid-bass diaphragm 11b of the mid-bass speaker 10 b. In yet another preferred example of the sound producing method of the present invention, the diaphragms 11 of the speakers 10 are oriented in opposite directions.
Further, in a preferred example of the sounding method of the present invention, the sounding method includes the steps of: allowing the tweeter 10a to reflect sound waves generated by the mid-bass speaker 10b in all directions so that a listener can hear a better sound effect around the sound effect device. Specifically, the surface of the tweeter frame 12a of the tweeter 10a facing the mid-bass diaphragm 11b of the mid-bass speaker 10b forms a spherical surface such that when the mid-bass speaker 10b generates sound waves in response to input of an audio signal, the spherical surface of the tweeter frame 12a of the tweeter 10a can reflect the sound waves generated by the mid-bass speaker 10b in all directions.
Optionally, in another preferred example of the sounding method of the present invention, the sounding method includes the steps of: the support 23 of the support unit 20 for maintaining the direction of sound radiation of the tweeter 10a to the woofer 10b is allowed to radiate sound waves generated by the woofer 10b in all directions, so that a listener can hear a better sound effect around the sound effect device. Specifically, the tweeter 10a is held in the sound wave radiation direction of the mid-woofer 10b by the support unit 20, and the surface of the support portion 23 of the support unit 20 facing the mid-woofer diaphragm 11b of the mid-woofer 10b forms a spherical surface so that when the mid-woofer 10b generates sound waves in response to input of an audio signal, the spherical surface of the support portion 23 can reflect the sound waves generated by the mid-woofer 10b in all directions. Preferably, the tweeter 10a is hidden inside the support 23 to allow the spherical surface of the support 23 to directly face the diaphragm of the mid-woofer 10a, thus allowing the spherical surface of the support 23 to uniformly reflect sound waves generated by the mid-woofer 10b in all directions.
