Abstract
Description
Technical Field
[0001] This utility model relates to the field of acoustic equipment, and in particular to audio equipment. Background Technology
[0002] Currently, due to the diverse shapes of speakers and the presence of multiple electronic components inside, these components are typically placed inside the speaker cavity to match the specific design of the speaker, without any specific and advantageous placement rules. This results in a severely uneven and uneven surface inside the speaker cavity, significantly increasing the superposition and cancellation of audio sound waves and the effect of standing waves. This leads to large fluctuations in the acoustic curve, causing considerable trouble and difficulty for the later tuning of the speaker.
[0003] The technical problem to be solved by this application is: how to reduce the impact of the placement of electronic components on audio. Utility Model Content

The sound transmission box is provided with a sound transmission inner cavity and a speaker. The mounting box is provided with a mounting inner cavity and a mounting outer shell. The mounting outer shell is disposed on the outer wall of the rear end of the sound transmission box and fixed to the sound transmission box. The speaker is mounted on the front end of the sound transmission inner cavity. The mounting inner cavity is disposed between the outer wall of the rear end of the sound transmission box and the mounting outer shell. The electronic components are disposed in the mounting inner cavity.
[0006] In some embodiments, the electronic device is provided with external operation keys for communication connection, and the external operation keys are located on the outer surface of the mounting housing.
[0007] In some implementations, the microphone enclosure and the mounting enclosure are detachably connected.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1 This utility model provides a technical solution: an externally mounted speaker, including electronic components 1 and a front and rear sound transmission enclosure and a mounting enclosure.
[0019] Please see Figures 1-3 The sound-transmitting enclosure contains a sound-transmitting inner cavity 21 and a speaker 22. The mounting enclosure contains a mounting inner cavity 31 and a mounting outer shell 32. The mounting outer shell 32 is fixedly mounted outside the mounting inner cavity 31. The sound-transmitting inner cavity 21 is an axisymmetric shape, and its cross-section is circular or rectangular. The rear end of the sound-transmitting inner cavity 21 is connected to the mounting outer shell 32, and the front end has a sound-transmitting circular hole. The speaker 22 is located at the front end of the sound-transmitting inner cavity 21, with its magnet end facing inward towards the sound-transmitting inner cavity 21. The number and position of the speakers 22 can be set as needed. Electronic components 1 can be a power amplifier board, a preamplifier board, a battery, and a crossover. Several electronic components 1 are reasonably distributed in the space around the mounting inner cavity 31 to reduce overall weight imbalance. Electronic components 1 have external operation keys for communication connection, which are located on the outer surface of the mounting outer shell 32. The external operation keys include buttons, knobs, and switches, etc., which are electronic operation keys for human interaction. Electronic device 1 dissipates heat directly through mounting housing 32, which can be made of metal to increase heat dissipation efficiency.
[0020] The inner wall of the sound transmission cavity 21 is smooth, and all included angles of the inner wall of the sound transmission cavity 21 are not less than 90°, which reduces standing waves and creates a better sound field space.
[0021] Since the mounting cavity 31 is located in the external space of the sound transmission cavity 21, the sound transmission cavity 21 and the mounting cavity 31 are independent and do not interfere with each other. The electronic device 1 is located inside the mounting cavity 31. Specifically, the electronic device 1 is fixed to the outer wall of the sound transmission cavity 21 or to the inner wall of the mounting housing 32. Therefore, the sound transmission cavity 21 can have a relatively complete independent cavity, thereby creating a better sound field space. The size and shape of the mounting housing 32 can be reasonably adjusted as needed, so that the mounting cavity 31 leaves enough space for the electronic device 1, thereby providing more flexible selection space for the electronic device 1 and obtaining a more flexible appearance for the mounting housing 32.
[0022] To facilitate speaker charging, in this embodiment, preferably, the speaker enclosure and the mounting enclosure are detachably connected, allowing for easy battery replacement. The battery is a removable rechargeable battery, meaning the entire speaker can be charged, or only the battery can be removed for charging, enhancing convenience. Furthermore, the speaker enclosure and the mounting enclosure are formed independently during manufacturing, and their surfaces can be customized to meet individual customer needs. The mounting housing 32 can also be adjusted in size or shape according to customer requirements.
[0023] The working principle of this utility model is as follows: Due to the symmetrical spatial structure of the sound transmission cavity 21 and its independent and non-interfering nature with the installation cavity 31, the inner wall of the sound transmission cavity 21 has a greater degree of smoothness, thereby creating a more ideal audio sound field space and obtaining a smoother acoustic curve, laying a good foundation for the good sound quality performance of the audio system.
[0024] In this embodiment, the enclosure consists of an independent and complete sound transmission enclosure and a mounting enclosure. The speaker 22 is located at the front end of the sound transmission cavity 21, while the location of the vents is variable. In this embodiment, the vents are located at the lower front end of the sound transmission cavity 21 and are positioned on both sides of the speaker 22. The electronic device 1 and the speaker 22 are respectively housed in their respective, separate mounting cavities 31 and sound transmission cavities 21. Therefore, this is significantly different from the traditional, common type of speaker that lacks a complete, independent, and tightly connected acoustic cavity body and mounting space, where the acoustic cavity body also serves as the mounting space for the electronic device 1, and the electronic device 1 is either exposed or built into a sealed chamber and mounted on the inner wall of the acoustic cavity body. This embodiment is a single-piece external acoustic speaker.
[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
