Description

Technical Field

[0001] The present invention relates to the field of audio technology, and in particular to a sound generating unit provided with a shock absorbing structure. Background Art

[0002] In order to better solve the echo and noise problems, the existing mechanism design generally uses a single speaker with low power, such as a 3-watt single speaker. This is because when the speaker makes a sound, the speaker and the sound cavity will produce obvious vibrations. The vibration will produce irregular noises, which will be transmitted to the device's microphone or microphone array. The noise generated by the vibration is basically impossible to isolate from the structure, and it is also difficult to separate and eliminate it algorithmically. If the power of the speaker is relatively large, it will be more difficult to handle. In severe cases, the device can be seen to be jumping obviously. Summary of the invention

[0025] Figure 1 is an exploded view of a sound generating unit provided with a shock absorbing structure in this embodiment; Figure 2 yes Figure 1Axonometric view of the first shell element in . Figure 3 yes Figure 1 Axonometric view of the second shell element in . Figures 1 to 3 As shown, this embodiment provides a sound-emitting unit provided with a shock-absorbing structure, and the sound-emitting unit includes a shell 1, a first sound cavity 112 and a second sound cavity 122 arranged in the shell 1, a first speaker 13 matched with the first sound cavity 112, and a second speaker 14 matched with the second sound cavity 122; a partition is arranged between the first sound cavity 112 and the second sound cavity 122, and preferably, the first speaker 13 and the second speaker 14 are symmetrically arranged along the partition, and the pronunciation holes of the first sound cavity 112 and the second sound cavity 122 are both located at the two ends of the shell 1, that is, pronunciation holes are respectively opened at the opposite ends of the shell 1, so that the first speaker 13 and the second speaker 14 sound in opposite directions.

[0026] In the present embodiment, since the first speaker 13 and the second speaker 14 are symmetrically arranged along the partition, when the product parameters of the first speaker 13 and the second speaker 14 are consistent and the played audio is exactly the same, the vibrations generated by the first speaker 13 and the second speaker 14 along the length direction of the shell 1 will be completely opposite and have the same vibration magnitude. Subsequently, without affecting the normal operation of the sound unit, the vibrations generated by the first speaker 13 and the second speaker 14 cancel each other out, so that the vibration generated by the entire sound unit is greatly reduced, thereby making the sound unit more stable and reliable when working.

[0027] To be more specific, in order to improve the sound quality of the sound unit on the basis of the above-mentioned shock absorption in the present embodiment, preferably, the present embodiment further provides a first sound leakage channel and a second sound leakage channel on the partition, wherein the first sound leakage channel is connected to the first sound cavity 112, and the second sound leakage channel is connected to the second sound cavity 122. In order to prevent the first sound cavity 112 and the second sound cavity 122 from being connected in series, preferably, the first sound leakage channel and the second sound leakage channel in the present embodiment are not connected to each other.

[0028] Further preferably, the first sound leakage channel in the present embodiment includes a first cavity 114 opened in the partition, and a first through hole 113 arranged at the head end of the first cavity 114 for connecting the first cavity 114 with the first sound cavity 112; the second sound leakage channel includes a second cavity 124 opened in the partition, and a second through hole 123 arranged at the head end of the second cavity 124 for connecting the second cavity 124 with the second sound cavity 122; the first through hole 113 is arranged adjacent to the end opening of the second sound leakage channel; the second through hole 123 is arranged adjacent to the end opening of the first sound leakage channel, and the end openings of the first sound leakage channel and the second sound leakage channel arranged in this structure are both arranged in a trumpet shape.

[0029] The first sound leakage channel and the second sound leakage channel of the above-mentioned structural design can make the vibrating airflow generated by the first speaker 13 and the second speaker 14 when working flow outward along the corresponding first sound leakage channel and the second sound leakage channel respectively, avoiding affecting the sound environment in the first sound cavity 112 and the second sound cavity 122, thereby further optimizing the sound quality of the sound unit.

[0030] More preferably, as a preference, in this embodiment, grooves 15 are opened on the two opposite outer side walls of the shell 1, and the end opening of the first sound leakage channel and the end opening of the second sound leakage channel are respectively connected with the corresponding grooves 15. When the sound in the first sound cavity 112 and the second sound cavity 122 flows outward along the corresponding first sound leakage channel and the second sound leakage channel following the air flow, it can be dispersed to both sides of the shell 1 through the two grooves 15 on the two opposite outer side walls of the shell 1, thereby making the sound dispersion more uniform.

[0031] As a further preference, in order to facilitate the processing of the first cavity 114 and the second cavity 124, the shell 1 in this embodiment includes a first shell unit 11 and a second shell unit 12 that are tightly combined, and the first shell unit 11 includes a first shell 111 provided with a first sound cavity 112, and a first partition 115 integrally provided with the first shell 111; the second shell unit 12 includes a second shell 121 provided with a second sound cavity 122, and a second partition 125 integrally provided with the second shell 121. The first cavity 114 and the second cavity 124 are opened on the outer side walls of the first partition 115 and the second partition 125, and then the first partition 115 and the second partition 125 are tightly fitted to form the above-mentioned first cavity 114 and the second cavity 124. This structural setting can facilitate the processing and forming of the first cavity 114 and the second cavity 124. In this embodiment, in order to facilitate the stable and reliable connection of the first shell unit 11 and the second shell unit 12 as a whole, the first shell unit 11 and the second shell unit 12 can be firmly bonded together by applying strong glue on the outer side walls of the first partition 115 and the second partition 125.

[0032] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
