Description

Technical Field

[0001] This utility model relates to the field of high-intensity sound technology, and in particular to an omnidirectional high-intensity sound device. Background Technology

[0002] A loudspeaker is a common high-powered sound device, also known as a "horn." It is a widely used electroacoustic transducer that converts electrical signals into sound signals. Loudspeakers are widely used in audio equipment, televisions, mobile phones, automobiles, public address systems, and other applications. The driver head is the key component of a loudspeaker, responsible for converting electrical signals into sound. The driver head typically consists of a diaphragm, a voice coil, and a magnet. When an audio current passes through the voice coil, the voice coil experiences a force in the magnetic field, causing the diaphragm to vibrate, thereby pushing air to produce sound. In related technologies, a loudspeaker generally has only one driver head, and a single driver head can only propagate sound in a single direction.

[0003] In some application scenarios, such as public safety systems and emergency systems, high-powered sound devices are required to have a wide range of high-powered sound and a good high-powered sound effect. In order to achieve the purpose of high-powered sound, some related technologies directly integrate multiple speakers into one device to obtain a high-powered sound device. In this type of high-powered sound device, the multiple speakers are oriented in different directions, and this type of high-powered sound device needs to integrate a large number of speakers. Utility Model Content

[0004] To overcome at least one of the defects of the prior art, this utility model provides an omnidirectional high-intensity sound device. Through the cooperation of the housing, the drive head assembly structure and the drive head, the drive head expands the sound outward in all directions upward, and expands the sound outward downward using the first sound guide hole and the second sound guide hole, thereby increasing the sound range and enhancing the sound effect. Moreover, at least two sound units can be detachably connected together along the first direction through the connecting structure. The sound units can be added or removed according to actual needs, making it convenient to use.

[0039] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0040] See Figures 1 to 4 This utility model discloses an omnidirectional high-intensity sound device, comprising: a speaker unit 10, the speaker unit 10 including a housing 101, a drive head merging structure 102 and at least two drive heads 103, the drive heads 103 and the drive head merging structure 102 are both disposed in the inner cavity of the housing 101, and a first sound guide hole 104 is provided at the lower part of the housing 101; at least two drive heads 103 are evenly disposed around the central axis of the drive merging structure at the upper part of the drive merging structure, the openings of the drive heads 103 are inclined upwards, and a second sound guide hole 105 is provided at the lower part of the drive head merging structure 102, the first sound guide hole 104 and the second sound guide hole 105 are interconnected; a connecting structure 30, at least two speaker units 10 are detachably connected together along a first direction through the connecting structure 30, the connecting structure 30 including connectors 301 corresponding to the drive heads 103 one by one.

[0041] This utility model utilizes the cooperation of the housing 101, the drive head assembly structure 102, and the drive head 103. The drive head 103 expands the sound outward in all directions upward, and expands the sound outward downward using the first sound guide hole 104 and the second sound guide hole 105, thereby increasing the sound range and enhancing the sound effect. Moreover, at least two speaker units 10 can be detachably connected together along the first direction through the connecting structure 30, and speaker units 10 can be added or removed according to actual needs, making it convenient to use.

[0042] In this embodiment of the utility model, the drive head assembly structure 102 includes a connector 1021 that corresponds one-to-one with the drive head 103. The connector 1021 is inclined. The setting direction of the connector 1021 has an angle with the first direction, and the angle ranges from 30° to 80°.

[0043] For example, see Figure 3 The omnidirectional high-intensity sound device includes four drive heads 103. The drive head merging structure 102 includes four connectors 1021 that are arranged one-to-one with the drive heads 103. The angle between the arrangement direction of the connectors 1021 and the first direction is 45°. When the drive head 103 is connected to the connector 1021, the angle between the drive head 103 and the first direction is also 45°, so that the drive head 103 can project sound in the 45° direction.

[0044] Since the opening of the drive head 103 is tilted upwards, the four drive heads 103 are evenly arranged on the upper part of the drive converging structure around the central axis of the drive converging structure, thereby achieving surround sound amplification.

[0045] Furthermore, since the opening of the drive head 103 is tilted upwards, the four drive heads 103 are evenly arranged around the central axis of the drive converging structure at the upper part of the drive converging structure. The four drive heads 103 converge at the drive head converging structure 102 through their respective connectors 1021. That is to say, the opening of the drive head 103 faces the connector 301, and the tails of the drive heads 103 converge at the drive head converging structure 102. Thus, after the tails of the four drive heads 103 converge at the drive head converging structure 102, they emit sound downwards through the first sound guide hole 104 and the second sound guide hole 105. Therefore, the sound from the four drive heads 103 converging towards the first sound guide hole 104 and the second sound guide hole 105 is relatively concentrated, and the energy loss of the sound is not too great.

[0046] Of course, the number of driver heads 103 can be three, five or six, depending on the actual application scenario, and there is no limitation.

[0047] In this embodiment of the utility model, the drive head assembly structure 102 further includes a fixing member 1022 and an adapter 1024, and the first end of the connector 1021 is connected to the fixing member 1022. The lower part of the fixing member 1022 is provided with a second sound guide hole 105, and the second end of the connector 1021 is connected to the corresponding drive head 103 through the adapter 1024.

[0048] For example, see Figure 3 The adapter 1024 is an adapter plate, and the fixing part 1022 is a fixing plate. Since the connector 1021 and the drive head 103 are both inclined, the adapter 1024 connects the corresponding connector 1021 and drive head 103 together with screws. The adapter 1024 can be supported on the fixing part 1022 or the lower part of the housing 101, thereby improving the connection stability between the connector 1021 and the drive head 103.

[0049] Continue reading Figure 3 Since the drive head 103 is tilted, the connector 1021 is provided to facilitate the assembly of the drive head 103. The drive head 103 only needs to be connected to the connector 1021. If the drive head 103 is directly installed on the housing 101, the assembly difficulty of the drive head 103 will be increased.

[0050] Because the connector 1021 is tilted, the fastener 1022 is integrated with the connector 1021. The connector 1021 and the fastener 1022 can be produced as a single component. During assembly, it is only necessary to connect the fastener 1022 to the housing 101, which facilitates the assembly of the connector 1021. If the connector 1021 is directly installed on the housing 101, the assembly difficulty of the connector 1021 will be increased.

[0051] Furthermore, a second sound guide hole 105 is provided on the fixing member 1022 to prevent the fixing member 1022 from obstructing the downward sound amplification of the driving head 103; the diameter of the first sound guide hole 104 is greater than or equal to the diameter of the second sound guide hole 105, thereby facilitating sound amplification.

[0052] In this embodiment of the utility model, the drive head merging structure 102 further includes a support member 1023, which is disposed between the connector 1021 and the fixing member 1022. The connector 1021 is cylindrical, and the support member 1023 has an arc-shaped portion 1025 for supporting the connector 1021.

[0053] For example, see Figure 3 Since both the connector 1021 and the drive head 103 are inclined, the connection stability of the connector 1021 and the drive head 103 can be improved by supporting the connector 1021 with the support member 1023.

[0054] Of course, in other embodiments, the support member 1023 may also be disposed between the drive head 103 and the fixing member 1022, the drive head 103 is cylindrical, and the support member 1023 has an arcuate portion 1025 for supporting the drive head 103.

[0055] In this embodiment of the present invention, there is a sound gap between two adjacent sound-speaking units 10 in the first direction, and the sound gap is connected to the first sound guide hole 104.

[0056] For example, see Figure 3 The four drive heads 103 converge on the drive head merging structure 102, and the sound emitted by the four drive heads 103 can propagate downwards from the first sound guide hole 104, the second sound guide hole 105 and the sound gap.

[0057] In this embodiment of the present invention, at least one portion of the connector 301 extends into the inner cavity of the housing 101, and the portion of the connector 301 extending into the inner cavity of the housing 101 is disposed toward the opening of the drive head 103.

[0058] In this embodiment of the utility model, the connector 301 includes a first connector 3011, a second connector 3012, and a connecting post 3013; the upper part of the housing 101 is provided with the first connector 3011, which extends from the outside of the housing 101 to the inner cavity of the housing 101. The first connector 3011 is correspondingly provided with the driving head 103, and the portion of the first connector 3011 extending into the inner cavity of the housing 101 faces the opening of the driving head 103; the lower part of the housing 101 is provided with the second connector 3012, which extends from the outside of the housing 101 to the inner cavity of the housing 101; in two adjacent speaker units 10 in the first direction, the first connector 3011 on the latter speaker unit 10 is detachably connected to the first end of the connecting post 3013, and the second connector 3012 on the former speaker unit 10 is detachably connected to the second end of the connecting post 3013.

[0059] For example, see Figure 2 as well as Figure 4 The speaker unit 10 can be added or removed by disassembling and assembling the connecting column 3013, making it easy to use.

[0060] In this embodiment of the utility model, a first connecting seat 3011 is provided with a first connecting hole, and a second connecting seat 3012 is provided with a second connecting hole. In two adjacent speaker units 10 in the first direction, the first end of the connecting post 3013 is inserted into the first connecting seat 3011 on the latter speaker unit 10, and the second end of the connecting post 3013 is inserted into the first connecting seat 3011 on the former speaker unit 10.

[0061] Of course, in other embodiments, the first end of the connecting post 3013 is provided with a first connecting hole, and the second end of the connecting post 3013 is provided with a second connecting hole. In two adjacent speaker units 10 in the first direction, the first end of the connecting post 3013 is sleeved on the first connecting seat 3011 on the latter speaker unit 10, and the second end of the connecting post 3013 is sleeved on the first connecting seat 3011 on the former speaker unit 10.

[0062] In this embodiment of the utility model, the housing 101 includes an upper cover 1011 and a lower cover 1012 that are fastened together; the upper cover 1011 and the lower cover 1012 are fastened together to form a spherical or ellipsoidal inner cavity.

[0063] For example, see Figures 2 to 4The upper cover 1011 is shaped like a trumpet, a saucer, or a bowl, and the lower cover 1012 is shaped like a trumpet, a saucer, or a bowl. Thus, the upper cover 1011 and the lower cover 1012 are fastened together to form a spherical or ellipsoidal inner cavity. The spherical or ellipsoidal inner cavity formed by the upper cover 1011 and the lower cover 1012 is the inner cavity of the shell 101. That is to say, both the upper cover 1011 and the lower cover 1012 have arc-shaped outer surfaces. The sound emitted by the drive head 103 is discharged through the upper cover 1011, the lower cover 1012, and the connector 301.

[0064] Continue reading Figures 2 to 4 The lower cover 1012 is provided with a first sound guide hole 104, and the fixing member 1022 is provided with a second sound guide hole 105. The first sound guide hole 104, the second sound guide hole 105 and the housing 101 are coaxially arranged. That is to say, the first sound guide hole 104 is aligned with the arc-shaped top of the upper cover 1011. The sound emitted by the drive head 103 can diffuse downward and around through the second sound guide hole 105 and the first sound guide hole 104 and along the arc-shaped top of the upper cover 1011, thereby increasing the sound range and enhancing the sound effect.

[0065] In this embodiment of the invention, the first direction is the longitudinal direction, and at least two speaker units 10 are connected in series from top to bottom; the omnidirectional high-intensity sound device also includes a support frame 40, which is disposed at the bottom of the speaker unit 10 located at the bottom.

[0066] For example, see Figure 1 as well as Figure 2 The omnidirectional high-intensity sound device is placed on the ground or tabletop using a support frame 40. Since the lowermost speaker unit 10 is close to the ground or tabletop, the inner cavity of the lowermost speaker unit 10 may not be equipped with a drive head 103 and a drive head merging structure 102. When the omnidirectional high-intensity sound device is equipped with four speaker units 10, and the inner cavity of the lowermost speaker unit 10 is not equipped with a drive head 103 and a drive head merging structure 102, the omnidirectional high-intensity sound device is a four-disc, three-layer speaker structure. Of course, the number of speaker units 10 in the omnidirectional high-intensity sound device is not limited and can be increased or decreased according to the actual application scenario.

[0067] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
