The embodiment of the utility model provides an interphone for improving a horn angle, which comprises the following steps: an interphone main body 1, a speaker 201, and a microphone 202;

The interphone body 1 has a thickness direction, a height direction and a width direction orthogonal to each other, the thickness direction being defined as a direction approaching or separating from one side of a human body when worn; the height direction is defined as the extending direction of the head and the foot of the human body; the thickness direction is perpendicular to the height direction and the width direction respectively;

Specifically, as shown in fig. 1 to 12, the thickness direction is the Z-axis direction shown by the coordinate axis in the figure, the height direction is the Y-axis direction shown by the coordinate axis, and the width direction is the X-axis direction shown by the coordinate axis;

As shown in fig. 1 and 4, the intercom main body 1 has a wearing surface 102 on the side close to the human body in the thickness direction and a pressing surface 101 on the side far from the human body in the thickness direction;

When the device is worn, the vibration directions of the loudspeaker 201 and the microphone 202 are between the height direction and the width direction and face the head position of the human body.

The arrangement of the horn 201 on the one hand helps to reduce the scattering and attenuation of sound in the air, which can improve the clarity and accuracy of the sound; on the other hand, the interference of environmental noise on sound transmission is reduced;

For microphone 202, microphone 202 receives primarily sound from its direction of orientation, rather than ambient noise.

Further, as shown in fig. 3 and 6, the interphone body 1 further has a side surface 103 connecting the wearing surface 102 and the pressing surface 101; the sound outlet 301 and the sound receiving hole 302 are arranged on the side surface 103, the sound outlet 301 is arranged in the vibration direction of the loudspeaker 201, and the sound receiving hole 302 is arranged in the vibration direction of the microphone 202;

In the wearing state, as shown in fig. 9 and 10, the included angle between the extending direction and the height direction of the sound outlet 301 of the speaker 201 is between 0 degrees and 63.5 degrees when viewed along the thickness direction;

as shown in fig. 12, the angle between the extending direction and the height direction of the sound outlet 301 of the speaker 201 is between 0 degrees and 80.5 degrees as viewed in the width direction.

In the above range, the propagation effect of the loudspeaker 201 is relatively good, which is helpful for optimizing the use experience of the user, ensuring that the sound is relatively clear and the tone quality is relatively good.

Further, as shown in fig. 3 and 6, the speaker 201 and the microphone 202 are disposed on the same side;

On the one hand, the problems that when the loudspeaker 201 and the microphone 202 are close to each other but located on different sides 103, echo and howling are generated when sound propagates in the air can be solved; providing speaker 201 and microphone 202 on the same side reduces echo and howling, providing clearer voice transmission;

On the other hand, the speaker 201 and the microphone 202 are disposed on the same side, so that the user's operation and control are facilitated: when the loudspeaker 201 and the microphone 202 are worn and used, a user more naturally faces the loudspeaker 201 and the microphone 202, so that the loudspeaker is convenient to use, the gesture does not need to be adjusted too much, and the use experience of the user is improved;

In yet another aspect, the speaker 201 and the microphone 202 are disposed on the same side, which also helps to optimize the spatial layout and design of the intercom, making the intercom lighter and more portable.

Further, as shown in fig. 3, a rope hanging hole 5 for connecting a rope is further provided on one side of the interphone main body 1 provided with the loudspeaker 201 and the microphone 202, so as to realize a hanging wearing mode of the interphone;

Further, as shown in fig. 7 and 8, the intercom main body 1 is further provided with a back clip 6, and the wearing surface 102 is further provided with a magnetic attraction module along the thickness direction;

The magnetic module comprises a magnetic block (not shown in the figure) arranged on the interphone main body 1 and a magnetic seat 7 matched with the magnetic block for use,

The clothes can be clamped by the matching of the magnetic attraction block and the magnetic attraction seat 7, so that the clothes are convenient to wear;

the back clamp 6 and the magnetic attraction module are used for realizing different wearing modes.

Specifically, the wearing effect is as shown in fig. 9 to 12, and the wearing mode is diversified, so that the wearing mode is more convenient to operate and carry, the user can select the most suitable mode according to specific scenes and requirements, and the diversified use requirements of the user are met.

Further, the sound outlet 302 of the loudspeaker 201 and the sound receiving 302 of the microphone 202 are oriented differently, and the propagation path of the sound of the loudspeaker 201 and the propagation path of the sound of the microphone 202 are different;

That is, the propagation path of the sound of the loudspeaker 201 is different from the path of the sound received by the microphone 202, and no intersection exists or the intersection is quite limited, so that the interference influence between the two is reduced;

the microphone 202 and the loudspeaker 201 have different orientations, so that on one hand, the occurrence of an echo phenomenon can be effectively avoided, and the definition of sound is improved;

On the other hand, due to the design, the propagation path of the sound of the loudspeaker 201 cannot directly pass through the microphone 202, so that the interference of indirect sound waves on the microphone 202 is reduced, and the pointing performance of the microphone 202 is improved; this may allow the microphone 202 to more intensively receive sound in a specific direction, improving the quality and clarity of the speech signal.

In summary, the different orientations of the intercom microphone 202 and the speaker 201 can reduce echo, improve the directivity and clarity of sound, and reduce noise and environmental interference. Under the combined action of the factors, the sound quality effect of the interphone is improved, and the use experience of a user is optimized.

Further, the interphone main body 1 is provided with a cavity 4, and the loudspeaker 201 and the microphone 202 are arranged in different cavities 4;

Such a design, which in effect separates the locations of the loudspeaker 201 and the microphone 202, is also commonly referred to as acoustic isolation or separation;

For the external environment, the cavity 4 plays a role in protecting the loudspeaker 201 and the microphone 202, can isolate most of external interference noise, receives sound through the sound receiving hole 302 and releases the sound through the sound emitting hole 301, so that the directivity of sound receiving and releasing is enhanced;

Specifically, for the inside of the intercom, when the distance between the speaker 201 and the microphone 202 is too short, the sound may generate echo and affect the sound receiving effect of the microphone 202, and at the same time, the sound output by the speaker 201 may also directly enter the microphone 202, causing noise or noise; by separating the positions of the loudspeaker 201 and the microphone 202, the possibility of echo and interference can be effectively reduced, so that the definition and purity of the sound effect are improved.

In addition, when the speaker 201 and the microphone 202 are too close together, ambient noise is amplified and spread, affecting the quality of the sound effect.

In summary, in the interphone, the positions of the speaker 201 and the microphone 202 are set in different cavities 4, which is an important design factor for optimizing the sound effect, and can improve the definition and purity of the sound effect.

Further, as shown in fig. 2, the cavity 4 provided with the horn 201 gradually becomes smaller in size from inside to outside in the sound propagation direction;

The cavity 4 provided with the microphone 202 gradually becomes smaller in size from outside to inside in the sound propagation direction.

This design of tapering the dimensions of the cavities 4 of the loudspeaker 201 and microphone 202 in the direction of sound propagation is called acoustic waveguide.

The design of gradually reducing the size of the cavity 4 of the loudspeaker 201 and the microphone 202 along the sound propagation direction accords with the distance of the acoustic waveguide, so that the diffusivity and the directivity of the sound wave can be enhanced, the focusing power and the directivity of the sound are improved, and the sound effect experience of a user during use is optimized.

The gradually shrinking cavity 4 design can also reduce the scattering of sound; scattering refers to the phenomenon of reflection and diffusion of sound waves as they encounter obstacles or boundaries. By tapering the cavity 4, the collision of sound waves with the boundary of the cavity 4 can be reduced, thereby reducing the spread and reflection of sound, so that sound propagates more accurately to the target area.

During sound propagation, the energy of sound generally decays with increasing distance; the tapering cavity 4 design allows to control the degree of sound attenuation so that the sound maintains a high energy and sound quality during propagation.

In general, tapering the dimensions of the cavities 4 of the loudspeaker 201 and microphone 202 in the direction of sound propagation may provide better sound focusing, directionality, and accuracy. Such designs are commonly used in sound systems, speaker and microphone 202 arrays, and the like, to improve the sound transmission.

Further, the number of the sound outlet holes 301 includes one or more, and the sound outlet holes 301 are staggered up and down;

The staggered up and down sound outlet 301 layout may reduce audio problems due to resonance or distortion. The sound wave may interfere or reflect with other components during the propagation process, and the staggered arrangement of the sound outlet holes 301 may reduce the problem, thereby improving the quality and definition of the audio.

The embodiment of the utility model has at least the following beneficial effects:

the embodiment of the utility model provides an interphone for improving the angle of a loudspeaker 201, which optimizes the setting position and the orientation angle of the loudspeaker 201 and is beneficial to improving the communication tone quality; the sound outlet holes 301 are distributed in the vibration direction of the loudspeaker 201, the sound receiving holes 302 are distributed in the vibration direction of the microphone 202, the sound propagation directivity is further enhanced, the position distribution relation of the sound outlet holes 301 is optimized, the directions of the sound outlet holes 301 and the sound receiving holes 302 are different, the loudspeaker 201 and the microphone 202 are arranged in different cavities 4 on the same side, and the size of the cavity 4 provided with the loudspeaker 201 is gradually reduced along the sound propagation direction; the size of the cavity 4 provided with the microphone 202 gradually increases along the sound propagation direction; under the combined action of the design, the definition and purity of the sound effect are improved; a rope hanging hole 5, a back clamp 6 and a magnetic suction module are arranged; provides diversified wearing modes, and is more convenient to operate and carry.
