DETAILED DESCRIPTION

[0023] The following will explain the use of the fuse provided by the present invention to prevent a speaker unit from burning out, the speaker, the speaker structure, the vehicle speaker connector and the vehicle speaker through the implementation methods, but these implementation methods are not intended to limit the present invention to any environment, application or method as described in these implementation methods.

It should be understood that in the following implementation methods and drawings, elements that are not directly related to the technical features of the present invention have been omitted and are not described or / and illustrated. In addition, the dimensions of the elements in the drawings and the proportional relationship between the elements are only for the convenience of drawing and explanation, and are not intended to limit the scope of the present invention. Furthermore, unless otherwise specified, the "one", "the" and similar terms used in this specification and claims should be understood to include singular and plural forms.

[0024] Figure 1 Schematic diagram of a speaker structure 1 in some embodiments of the present invention. The speaker structure 1 includes a speaker unit 11 and a fuse 13 .

[0025] It should be noted that the present invention does not limit the solution of the speaker unit 11. For example, the speaker unit 11 can be a dynamic speaker unit, an inductive speaker unit, an electrostatic speaker unit, a planar speaker unit, a ribbon speaker unit or a horn speaker unit. In addition, the present invention does not limit the processing frequency range of the speaker unit 11. For example, the speaker unit 11 can be a woofer unit, a subwoofer unit, a midrange speaker unit, a tweeter unit, a super tweeter unit, a coaxial speaker unit or a full-range speaker unit.

[0026] It should be noted that the present invention does not limit the type of fuse 13. From the perspective of protection form, fuse 13 can be a temperature fuse or a current limiting fuse. From the perspective of volume, fuse 13 can be a large fuse, a medium fuse, a small fuse or a micro fuse. From the perspective of rated voltage, fuse 13 can be a high voltage fuse, a low voltage fuse, or a safety voltage fuse. From the perspective of breaking capacity, fuse 13 can have a high breaking capacity or a low breaking capacity. From the perspective of shape, fuse 13 can be a flat-headed tubular, a pointed tubular, a guillotine type, a spiral type, a plug-in type, a flat plate type, a wrap type, or a patch type. From the perspective of melting speed, the melting speed of fuse 13 can be very slow, slow, medium, fast, or very fast. From the perspective of standard, fuse 13 can be a European standard fuse, a US standard fuse, or a Japanese standard fuse.

[0027] For example, glass tube fuses, industrial ceramic package fuses (CeramicFuses), positive temperature coefficient (PTC) fuses, negative temperature coefficient (NTC) fuses, printed circuit board fuses and automotive plug-in fuses are some of the common fuses on the market.

[0028] The speaker unit 11 includes a positive input terminal 11a and a negative input terminal 11b. The positive input terminal 11a and the negative input terminal 11b are used to directly or indirectly receive audio signals, such as receiving audio signals output by an amplifier. The fuse 13 includes a first terminal 13a and a second terminal 13b.

[0029] exist Figure 1 In the illustrated embodiment, the first terminal 13a of the fuse 13 is connected to the positive input terminal 11a of the speaker unit 11. In these embodiments, if an audio signal from a device (e.g., an audio signal from an amplifier) ​​is to be provided to the speaker unit 11 for playback, the positive signal line of the device needs to be connected to the second terminal 13b, and the negative signal line of the device needs to be connected to the negative input terminal 11b. That is, the positive signal in the audio signal is transmitted to the positive input terminal 11a through the fuse 13, while the negative signal is directly transmitted to the negative input terminal 11b.

[0030] Since the first terminal 13a of the fuse 13 is connected to the positive input terminal 11a of the speaker unit 11, if the current of the audio signal from a device (for example, the audio signal from the amplifier) ​​is too large, the fuse 13 will block the current flowing to the speaker unit 11, thereby preventing the speaker unit 11 from burning. For example, if the fuse 13 is a primary temperature fuse, when the current of the audio signal is too large, the temperature of the fuse 13 will rise to its melting point and melt, so that the excessive current will not flow to the speaker unit 11, thereby preventing the speaker unit 11 from burning due to the excessive current. For another example, if the fuse 13 is a resettable fuse (for example, a positive temperature coefficient fuse), when the current of the audio signal is too large, the temperature of the fuse 13 will rise and the volume will expand, so that the connection network between the conductive particles is broken, becoming non-conductive or insulated, so that the excessive current will not flow to the speaker unit 11, thereby preventing the speaker unit 11 from burning.

[0031] It should be noted that Figure 1 In the illustrated embodiment, the connection between the fuse 13 and the speaker unit 11 is that the first terminal 13a of the fuse 13 is connected to the positive input terminal 11a of the speaker unit 11. However, in other embodiments, the fuse 13 and the speaker unit 11 may be connected in other ways. For example, the first terminal 13a of the fuse 13 may be connected to the negative input terminal 11b of the speaker unit 11, or the second terminal 13b of the fuse 13 may be connected to the positive input terminal 11a of the speaker unit 11, or the second terminal 13b of the fuse 13 may be connected to the negative input terminal 11b of the speaker unit 11. In these embodiments, if the current of the audio signal from a device (for example, the audio signal from an amplifier) ​​is too large, the fuse 13 will also block the current flowing to the speaker unit 11, thereby preventing the speaker unit 11 from burning out.

[0032] In addition, Figure 1 The speaker structure 1 in some embodiments of the present invention is shown. Figure 1 The above description also clearly shows that the fuse 12 is used to prevent the speaker unit 11 from burning out.

[0033] Figure 2 and Figure 3 is a schematic diagram of a loudspeaker 2 in some embodiments of the present invention, wherein Figure 2 is a three-dimensional schematic diagram of the loudspeaker 2, and Figure 3 2 is a side cross-sectional view of the speaker 2. The speaker 2 comprises a sound box 25, two speaker units 21, 23, a frequency division circuit 27 and two fuses 31, 33. The speaker units 21, 23 are both embedded in a front panel S of the sound box 25.

[0034] The present invention does not limit the scheme of the speaker units 21 and 23. The speaker units 21 and 23 can each be a dynamic speaker unit, an inductive speaker unit, an electrostatic speaker unit, a planar speaker unit, a ribbon speaker unit or a horn speaker unit. In addition, the present invention does not limit the processing frequency range of the speaker units 21 and 23. For example, the speaker units 21 and 23 can each be a woofer unit, a subwoofer unit, a midrange speaker unit, a tweeter unit, a super tweeter unit, a coaxial speaker unit or a full-range speaker unit. However, it should be noted that the speaker unit 21 has a first processing frequency range (not shown) that is different from the speaker unit 23. A second processing frequency range (not shown) has.

[0035] Similarly, the present invention does not limit the types of fuses 31 and 33. From the perspective of protection form, fuses 31 and 33 can be temperature fuses or current limiting fuses. From the perspective of volume, fuses 31 and 33 can be large fuses, medium fuses, small fuses or micro fuses. From the perspective of rated voltage, fuses 31 and 33 can be high voltage fuses, low voltage fuses, and safety voltage fuses. From the perspective of breaking capacity, fuses 31 and 33 can have high breaking capacity or low breaking capacity. From the perspective of shape, fuses 31 and 33 can be flat-headed tubular, pointed-headed tubular, guillotine-shaped, spiral-shaped, insert-shaped, flat-plate-shaped, wrapped-shaped, and patch-shaped. From the perspective of melting speed, the melting speed of each fuse 31 and 33 can be very slow, slow, medium, fast, or very fast. From the perspective of standards, the fuses 31 and 33 can be European standard fuses, American standard fuses or Japanese standard fuses.

[0036] The frequency division circuit 27 is used to perform a first filtering process (not shown) on an audio signal 30 from a device (for example, an audio signal from an amplifier) ​​to generate a first frequency division signal 301, perform a second filtering process (not shown) on the audio signal 30 to generate a second frequency division signal 303, and provide the first frequency division signal 301 and the second frequency division signal 303 to the speaker unit 21 and the speaker unit 23 respectively.

[0037] The speaker unit 21 includes a positive input terminal 21a and a negative input terminal 21b. The fuse 31 includes a first terminal 31a and a second terminal 31b. Figure 3In the illustrated embodiment, the first terminal 31a of the fuse 31 is connected to the positive input terminal 21a of the speaker unit 21. In these embodiments, the positive signal line in the first group of signal lines of the frequency division circuit 27 is connected to the second terminal 31b of the fuse 31, and the negative signal line in the first group of signal lines is connected to the negative input terminal 21b of the speaker unit 21. That is, the positive signal in the audio signal 301 is transmitted to the positive input terminal 21a through the fuse 31, and the negative signal in the audio signal 301 is directly transmitted to the negative input terminal 21b. Since the first terminal 31a of the fuse 31 is connected to the positive input terminal 21a of the speaker unit 21, if the current of the audio signal 301 is too large, the fuse 31 will block the current flowing to the speaker unit 21, thereby preventing the speaker unit 21 from burning.

[0038] Similarly, the speaker unit 23 includes a positive input terminal 23a and a negative input terminal 23b. The fuse 31 includes a first terminal 33a and a second terminal 33b. Figure 3 In the illustrated embodiment, the first terminal 33a of the fuse 33 is connected to the positive input terminal 23a of the speaker unit 23. In these embodiments, the positive signal line in the second group of signal lines of the frequency division circuit 27 is connected to the second terminal 33b of the fuse 33, and the negative signal line in the second group of signal lines is connected to the negative input terminal 23b of the speaker unit 23. That is, the positive signal in the audio signal 303 is transmitted to the positive input terminal 23a through the fuse 33, and the negative signal in the audio signal 303 is directly transmitted to the negative input terminal 23b. Since the first terminal 33a of the fuse 33 is connected to the positive input terminal 23a of the speaker unit 23, if the current of the audio signal 303 is too large, the fuse 13 will block the current flowing to the speaker unit 23, thereby preventing the speaker unit 23 from burning.

[0039] It should be noted that in other embodiments, the fuse 31 and the speaker unit 21 may be connected in other ways, and the fuse 33 and the speaker unit 23 may be connected in other ways. In short, according to the spirit of the present invention, the connection between the fuse 31 and the speaker unit 21 may be: one of the first terminal 31a and the second terminal 31b is connected to one of the positive input terminal 21a and the negative input terminal 21b. The connection between the fuse 33 and the speaker unit 23 may be: one of the first terminal 33a and the second terminal 33b is connected to one of the positive input terminal 23a and the negative input terminal 23b. In these embodiments, if the current of the audio signal 301 is too large, the fuse 31 will block the current flowing to the speaker unit 21, thereby preventing the speaker unit 21 from burning. In addition, if the current of the audio signal 303 is too large, the fuse 33 will block the current flowing to the speaker unit 23, thereby preventing the speaker unit 23 from burning.

[0040] It should be noted that in other embodiments, the speaker may include other numbers of speaker units, and the positive input terminal and the negative input terminal of each speaker unit are connected to one of the first terminal and the second terminal of a fuse. With this configuration, if the current of the audio signal flowing to a speaker unit is too large, the corresponding fuse will block the current flowing to the speaker unit, thereby preventing the speaker unit from burning. In addition, if the speaker includes only one speaker unit, the speaker may not be configured with a frequency division circuit.

[0041] Figure 4 1 is a top view of a vehicle horn connector 4 in some embodiments of the present invention. The vehicle horn connector 4 includes a housing 41, two metal components 43, 45 and a fuse 13, wherein the type and function of the fuse 13 are similar to those of the fuses in the above embodiments.

[0042] The metal element 43 is fixed to the housing 41 and extends from the inside of the housing 41 to the outside of the housing 45. In addition, the metal element 45 is fixed to the housing 41 and extends from the inside of the housing 41 to the outside of the housing 45. The present invention does not limit the material of the metal elements 43 and 45, but in some embodiments, the metal elements 43 and 45 can each be a copper sheet. Figure 4 In the illustrated embodiment, the first terminal 13 a of the fuse 13 is connected to the metal element 43 .

[0043] The housing 41 can be installed on a speaker unit having a positive input terminal and a negative input terminal (for example, a speaker unit installed in a car), so that the metal element 43 is electrically connected to the positive input terminal, and the metal element 45 is electrically connected to the negative input terminal.

[0044] In these embodiments, if an audio signal from a device (e.g., an audio signal from an amplifier) ​​is to be provided to the speaker unit for playback, the positive signal line of the device needs to be connected to the metal element 43, and the negative signal line of the device needs to be connected to the metal element 45. Since the first terminal 13a of the fuse 13 is connected to the metal element 43, the positive signal in the audio signal is transmitted to the positive input terminal of the speaker unit through the metal element 43 and the fuse 13, and the negative signal in the audio signal is transmitted to the negative input terminal of the speaker unit through the metal element 45. By connecting the fuse 13 to the metal element 43, if the current of the audio signal from a device is too large, the fuse 13 will block the current flowing to the positive input terminal of the speaker unit, thereby preventing the speaker unit from burning.

[0045] It should be noted that Figure 4In the illustrated embodiment, the first terminal 13a of the fuse 13 is connected to the metal element 43. However, in other embodiments, the first terminal 13a of the fuse 13 may be connected to the metal element 45, or the second terminal 13b of the fuse 13 may be connected to the metal element 43, or the second terminal 13b of the fuse 13 may be connected to the metal element 45. In these embodiments, if the current of the audio signal from a device is too large, the fuse 13 will also block the current flowing to the speaker unit, thereby preventing the speaker unit from burning out.

[0046] Figure 5 Schematic diagram of a vehicle horn 5 in some embodiments of the present invention. The vehicle horn 5 includes a horn unit 11 and a vehicle horn connector 4, wherein the horn unit 11 and the vehicle horn connector 4 are similar to those described in the above embodiments, so they are not repeated. In short, the horn unit 11 includes a positive input terminal 11a and a negative input terminal 11b, and the vehicle horn connector 4 includes a housing 41, two metal components 43, 45 and a fuse 13, and the first terminal 13a of the fuse 13 is connected to the metal component 43.

[0047] exist Figure 5 In the illustrated embodiment, the vehicle horn connector 4 is mounted on the horn unit 11, so that the metal element 43 is electrically connected to the positive input terminal 11a, and the metal element 45 is electrically connected to the negative input terminal 11b. Specifically, the metal element 43 is electrically connected to the positive input terminal 11a via the fuse 13, and the metal element 45 can be electrically connected to the negative input terminal 11b directly or via another metal element.

[0048] In these embodiments, if an audio signal from a device (e.g., an audio signal from an amplifier) ​​is to be provided to the speaker unit 11 for playback, the positive signal line of the device needs to be connected to the metal element 43, and the negative signal line of the device needs to be connected to the metal element 45. Therefore, the positive signal in the audio signal is transmitted to the positive input terminal 11a of the speaker unit 11 through the metal element 43 and the fuse 13, and the negative signal in the audio signal is transmitted to the negative input terminal 11b of the speaker unit 11 through the metal element 45. By providing the fuse 13 between the metal element 43 and the positive input terminal 11a, if the current of the audio signal from a device is too large, the fuse 13 will block the current flowing to the positive input terminal 11a of the speaker unit 11, thereby preventing the speaker unit 11 from burning out.

[0049] Need to explain, in Figure 5In the illustrated embodiment, the fuse 13 is disposed between the metal element 43 and the positive input terminal 11a, and the first terminal 13a is connected to the metal element 43, while the second terminal 13b is connected to the positive input terminal 11a. In other embodiments, the second terminal 13b may be connected to the metal element 43 instead, while the first terminal 13a is connected to the positive input terminal 11a. In addition, in some embodiments, the fuse 13 may be disposed between the metal element 45 and the negative input terminal 11b instead (i.e., one of the first terminal 13a and the second terminal 13b of the fuse is connected to the metal element 45, while the other is connected to the negative input terminal 11b). In these embodiments, if the current of the audio signal from a device is too large, the fuse 13 will also block the current flowing to the speaker unit 11, thereby preventing the speaker unit 11 from burning out.

[0050] In summary, the present invention provides a new use of a fuse, which is used to prevent a speaker unit from burning out. The present invention connects a fuse to the positive input terminal or the negative input terminal of the speaker unit, or connects a fuse to the metal element used to connect to the positive input terminal of the speaker unit or the metal element used to connect to the negative input terminal. In this way, if the current of the audio signal from a device is too large, the fuse will block the current flowing to the speaker unit, thereby preventing the speaker unit from burning out. The speaker, speaker structure, vehicle speaker connector and vehicle speaker provided by the present invention all have the aforementioned technology for preventing the speaker unit from burning out. Through the technology of the present invention, when assembling the audio system, the user does not need to worry about being unfamiliar with the performance of the various components of the audio system, which may cause the speaker unit to burn out during the assembly and / or testing process. In addition, when using the audio system to listen to music, the user does not need to worry about burning out the speaker unit due to improper operation.

[0051] The above embodiments are used to illustrate some embodiments of the present invention and to explain the technical features of the present invention, but are not used to limit the protection category and scope of the present invention.
