It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1 to 7, as shown in the drawings, a speaker audio includes: the loudspeaker comprises a passive film 1, a loudspeaker 2 and a sound shell 3, wherein the passive film 1 and the loudspeaker 2 are arranged on the sound shell 3; the passive film 1 comprises a first passive film and a second passive film, and the first passive film, the second passive film and the loudspeaker 2 are connected in a sealing way and are integrated into a whole; the sound shell is formed by clamping an upper sound cover 301 and a lower sound cover 302, the first passive film is arranged on the upper sound cover 301, the second passive film is arranged on the lower sound cover 302, and the first passive film and the second passive film are assembled in a vertically symmetrical mode.
In a specific implementation process, the first passive film and the second passive film are arranged in parallel up and down. In order to fix and completely close the upper cover and the lower cover of the sound box, as shown in fig. 1, the sound box 3 is configured in an L shape, so that when the speaker 2 works to make a sound, the movement of the speaker diaphragm compresses and expands the air in the sound box 3, and the first passive membrane and the second passive membrane vibrate under the action of the change of the air pressure. In general, in the process of transmitting sound in the air, the farther the distance is, the smaller the sound is heard, the loudspeaker sound of the invention is arranged in an L shape, the internal space of the loudspeaker sound of the invention is fully utilized, so that the internal space of the loudspeaker sound of the invention is smaller, the impact force of air flow generated by the sound emitted by the loudspeaker of the invention on the passive membrane is enhanced, and the passive membrane is arranged into the passive double membranes of the first passive membrane and the second passive membrane which are symmetrical up and down, so that the air flow is fully utilized when the first passive membrane and the second passive membrane vibrate up and down, and the sound is emitted in small and large volume, the sound is shocked, and the sound quality is restored to a higher effect. Set up first card reed and second card reed on the both sides of the longer partial outer end of stereo set casing in addition, the inside third card reed that sets up of the shorter partial lower extreme of stereo set casing, seal L type stereo set casing through three card reed and fix, the upper and lower lid of fixing the stereo set casing through this kind of mode has both sealed the fixing the stereo set casing, strengthen the whole seal of audio amplifier, traditional leading note pipe audio amplifier has effectively been solved, the air current sound that the during operation sent from leading note pipe, also accord with the design of this kind of L type loudspeaker stereo set simultaneously.
As shown in fig. 2 and 4, in a specific implementation process, each of the first passive film and the second passive film is composed of a soft adhesive layer 4, a reinforcing rib 5 and a weight plate 6, the soft adhesive layer 4 is connected with the reinforcing rib 5 to form a frame structure, the weight plate 6 is located inside the frame structure and integrally formed with the frame structure, and the weight plate 6 and the frame structure are fixedly connected and integrally formed through a first groove 8 and a second groove 9 which are arranged on the soft adhesive layer 4. In order to make the subsequent vibration amplitude of the passive membrane reach the maximum utilization after the passive membrane 1 is vibrated up and down for the first time, a counterweight plate is arranged in the frame structure, so that the weight of the passive membrane is increased, the resistance of the passive membrane to air is reduced in the up and down vibration process, and the effect of rapid attenuation of sound waves is reduced to a certain extent. In order to integrally form the weight plate and the frame structure, the first groove 8 and the second groove 9 are formed in the soft rubber layer 4, and the weight plate 6 is fixedly connected with the first groove 8 and the second groove 9 so as to prevent the passive film 1 from vibrating up and down too little due to too much connection between the weight plate 6 and the passive film 1, and indirectly cause the sound effect of the passive film not to shake.
In a more specific implementation process, the diameters of the first groove 8 and the second groove 9 are both 1-3mm, the length of the weight plate 6 is 24-25mm, the width of the weight plate is 6-7mm, the thickness of the weight plate is 0.6-0.7, the length of an outer frame of the frame structure is 29-30mm, the width of the outer frame of the frame structure is 11-12mm, and the length of an inner frame of the frame structure is 25-26mm and the width of the inner frame of the frame structure is 6-8 mm. Fig. 3 and 5 show a specific embodiment of the present invention, wherein the first groove 8 and the second groove 9 are both circular grooves with a diameter of 2 mm; the weight plate 6 is the cuboid, and the length of weight plate 6 is 24.40mm, the width is 6.4mm, thickness is 0.65mm, the length of frame construction's outer frame is 29.50mm, the width is 11.50mm, the length of frame construction's interior frame is 25.25mm, the width is 7 mm.
In a more specific implementation process, the soft rubber layer 4 and the reinforcing ribs 5 are made of rubber. The rubber is a high-elasticity polymer material with reversible deformation, is rich in elasticity at room temperature, can generate large deformation under the action of small external force, and can recover the original shape after the external force is removed, wherein the rubber material can be rubber, silica gel, thermoplastic polyurethane elasticity or thermoplastic elastomer and the like. The reinforcing rib 5 and the soft rubber layer 4 are made of rubber materials, so that the passive film 1 is manufactured only through a die in the manufacturing process, and the manufacturing process of the passive film 1 is optimized.
In a more specific implementation process, 8-12 reinforcing ribs are arranged on each of the first passive film and the second passive film, and the width of each reinforcing rib 5 is 0.5-1.5 mm. In the process of designing the passive film, the overhanging surface or the span of the passive film is possibly too large, and under the condition, the load which can be borne by the connecting surface of the passive film 1 is limited, so that the reinforcing rib is added on the passive film, and the passive film can bear more load after the connecting surface is added. Fig. 3 shows a specific embodiment of the present invention, wherein 10 reinforcing ribs are disposed on each of the first passive film and the second passive film, 3 reinforcing ribs are disposed on each of the upper frame and the lower frame of the passive film 1, the spacing between the reinforcing ribs of the upper frame of the passive film is 7.50mm, and the spacing between the reinforcing ribs of the lower frame of the passive film is also 7.50 mm; 2 reinforcing ribs are arranged on the left frame and the right frame of the passive film respectively, the distance between the reinforcing ribs of the left frame of the passive film is 2.50mm, and the distance between the reinforcing ribs of the right frame of the passive film is also 2.50 mm.
In a more specific implementation, the soft adhesive layer 4 includes a first planar substrate 101 extending outward and a plurality of arc-shaped skeletons forming the frame structure, and a second planar substrate 102 is arranged inside the arc-shaped skeletons. As shown in fig. 3 and 4, the arc-shaped frameworks are set to be in an R-ring shape, and the arc-shaped frameworks are provided with carved patterns, so that the problem that four corners of the frame structure can be communicated is solved, meanwhile, the passive membrane is not excessively in a tight state in the vibration process, and the vibration amplitude of the passive membrane is increased.
In a more specific implementation process, referring to fig. 1 and 4, the arc-shaped frameworks are arranged in a direction toward the inside of the sound box, so that the second substrate 102 and the plurality of arc-shaped frameworks of the framework structure form an empty avoiding position, and thus, the air flow in the sound box housing 3 can be buffered and enter the empty avoiding position when being compressed and expanded, and the vibration of the passive film is more balanced. Simultaneously add the sculpture line in arc skeleton department more be favorable to the passive membrane to stretch more easily at the process that the vibration got up, vibrate and get into the well easier, because arc skeleton department does not add the sculpture line and can make the passive membrane can only rely on the elasticity of rubber to vibrate completely at the in-process of vibration to appear the state of tightening in the vibration process, make the passive membrane damage more easily.
In a specific implementation process, the length of the first passive film and the second passive film is 30-40mm, the width of the first passive film and the second passive film is 15-20mm, and the height of the first passive film and the second passive film is 2-2.5 mm. Fig. 5 is a specific embodiment of the present invention, wherein the first and second passive films each have a length of 37mm, a width of 19mm, and a height of 2.25 mm.
In a specific implementation, as shown in fig. 6 and 7, the diameter of the horn is 30-35mm and the height is 11-12 mm. Fig. 7 shows a specific embodiment of the present invention, wherein the speaker 2 is an electrodynamic cone speaker, the speaker 2 is composed of a cone diaphragm 201, a centering leg 202 and a magnet ring 203, the diameter of the speaker 2 is 32.0mm, the diameter error is within 0.15mm, the height of the speaker 2 is 11.4mm, the height error is within 0.25mm, the parameter of the central value of fo (a musical scale) is 140Hz, the distance between the magnet ring 203 at the lower end of the speaker and the cone diaphragm 201 of the speaker is 6.3mm, and the thickness of the centering leg 202 of the speaker is set to 2.0 mm.
Fig. 8 is a graph showing a comparison of frequency responses of the acoustic horn of the present invention, in which the solid line corresponds to a conventional sound guide hole acoustic, and the dotted line corresponds to a passive dual-membrane acoustic, i.e., a horn acoustic provided in the present invention. It can be seen from fig. 8 that the frequency response curve of the horn sound of the present invention at 85Hz to 250Hz is smoother than that of the conventional via sound, and in addition, the average sound pressure of the horn sound of the present invention increases by 6dB in the range of 85Hz to 250Hz, while in fig. 8, the average sound pressure increase of the conventional via sound in the range of 85Hz to 250Hz is smaller than that of the horn sound of the present invention, and the average sound pressure increase refers to the frequency range in which the sound system can reproduce in the range of the amplitude, from which it can be seen that the degree of distortion of the horn sound of the present invention at 85Hz to 250Hz is smaller than that of the conventional via sound.
Fig. 9 is a comparison graph of harmonic distortion of the acoustic horn of the present invention, in which the solid line corresponds to the conventional leading hole acoustic, and the dotted line corresponds to the passive dual membrane acoustic, i.e., the horn acoustic provided in the present invention. Physically, we refer to the different vibrations in multiples of frequency as "harmonics" of each other, and harmonic distortion is actually a mathematically or statistically derived concept that does not exist alone, since its calculation must rely on the original signal. The general harmonic distortion is not as fearful as the imagination, and experiments show that general people can only generate the disgust for the harmonic distortion of more than 3 percent, and as can be seen from fig. 9, the distortion rates of the harmonic distortion of the loudspeaker sound of the invention within the range of 300-20000Hz are all lower than 3 percent, so that the loudspeaker sound of the invention can meet the related technical requirements on the aspect of harmonic distortion.
Fig. 10 is a comparison graph of impedance curves of the acoustic horn of the present invention, in which the solid line corresponds to the conventional sound leading hole sound, and the dotted line corresponds to the passive dual-membrane sound, that is, the horn sound provided in the present invention, and the impedance curve is a curve of the impedance value of the speaker varying with frequency. As the frequency changes, the impedance curve also changes, the impedance of the speaker is not a constant value, and a change in an impedance curve indicates that the impedance of the speaker is not a constant. The curve changes with the frequency. The impedance at the lowest point after the peak, we call it the nominal impedance of the speaker. The frequency corresponding to the impedance of the lowest point reached after the first peak is usually referred to as the lowest resonance frequency. As can be seen from fig. 10, the lowest resonant frequency value of the horn sound of the present invention is 95Hz, and the difference of the resonant frequency values is not much larger than that of the conventional via sound, so that the related technical requirements are met.
