摘要:
An alarm sound emitting apparatus (13) is installed inside an outer shell member (3) surrounding a space (11) and emits alarm sound to outside by vibrating an outer shell member. The alarm sound emitting apparatus is provided with a piezoelectric element (1) for generating vibration, a support rod (2) for supporting the piezoelectric element and transmitting vibration, an elastic member (4) for pressing the support rod to the vibrating plate (3), a magnet (5) for fixing the support rod to the vibrating plate, a circuit board (6) formed with various circuits including a circuit for driving the piezoelectric element, and a cabinet (7) for containing respective elements of the piezoelectric element and the like.

Ein Ultraschallwandler für ein Kraftfahrzeug umfasst ein Gehäuse (12) mit einem Basisteil (14) mit einer Aufnahmeöffnung (17), die durch eine Abdeckung (16) mindestens teilweise verschließbar ist. Um die Montage zu vereinfachen und sicherer zu gestalten, wird vorgeschlagen, dass die Abdeckung (16) einstückig durch eine flexible Materialbrücke (18) mit dem Basisteil (14) verbunden ist.
摘要:
A high quality electric-mechanical-acoustic transducer used mainly in mobile phones which is not damaged and degraded in performance by drop and impact. The transducer comprises at least one suspension (14) that supports a movable section (19) including a magnetic circuit portion (17) and a weight portion (13), and a frame (9) that supports a vibration plate (8) and the suspension (14) and defines a clearance within an elastic deformation range of the suspension (14) between the frame (9) and the outer circumference of the movable section (19). Even when the mobile terminal drops and the electric-mechanical-acoustic transducer built in it impacts, the suspension (14) can be prevented from being permanently deformed by the frame (9) receiving the outer circumference of the movable section (19).
摘要:
An electromagnetic sound generating body comprises a sound generator (13); a casing (12) having an upper case (14) and a lower case (15) combined together, the casing (12) incorporating the sound generator (13); a sound release hole (17) formed in the casing (12); and connector terminals (23) projecting from the casing (12). Because the electromagnetic sound generating body can be electrically connected to a printed circuit board simply by inserting the connector terminals (23) into external terminals, there is no need to surface-mount the electromagnetic sound generating body onto the printed circuit board. Therefore, vibrations of the electromagnetic sound generating body do not produce noise in the electronic components and circuits mounted on the printed circuit board. The casing (12) is attached with an adhesive member (36) in advance and then secured to an exterior case (35) by the adhesive member, and therefore the positional alignment between the sound release hole (17) of the casing and an external sound release hole (39) of the exterior case can be performed easily and reliably. Thus, in the case when the exterior case is that of a mobile phone, an incoming call indicator tone is prevented from being trapped inside the exterior case (35) of the phone.

A sound emitting assembly inserted into a body or frame (106) or handgrip of a personal transport means (90) said assembly comprising: (i) a package comprising an electronically actuated sound generator, an electronic circuit to feed a signal to the sound generator and a source of stored electric power, and (ii) an actuating switch (118) separated from the package and linked to the package by an electric pathway (119) such that when the switch (118) is activated by the user, a sound is emitted from said body or frame (106) or handgrip distant from the switch (118).
摘要:
The invention relates to a sound generator, especially for automotive parking assistance systems. Said sound generator comprises a housing (2) with a base (4) and a cover (6). Said base (4) comprises, coverable by the cover (6), a receptacle (8, 10) for receiving a membrane (38). The base (4), together with the cover (6), forms a one-piece connecting section (28), said base (4) and said cover (6) being movable relative to each other and being joined together by joining means (26).

摘要:
An electromagnetic sound generator has a case provided with a yoke, a magnet, a vibrating plate and a coil, and a pair of leads. An end of the coil and the other end of the leads is secured to the case so as to be connected to an outside terminal. A terminal connecting device is provided for connecting the end of the lead to the outside terminal. The terminal connecting device comprises a cylindrical case secured to the case, a connecting rod slidably mounted in the cylindrical case, and a coil spring provided in the cylindrical case to outwardly urge the connecting rod so as to be contacted with the outside terminal at an end of the rod. A top end of the cylindrical case is contacted with the end of the lead.
摘要:
Bei einem Signalhorn, insbesondere für Kraftfahrzeuge, mit einer Membran, die durch einen Antrieb bewegt wird und die auf eine Druckkammer wirkt, mit einem Trichter (1), der sich an die Druckkammer anschließt, der parallel zur Membran aufgewickelt ist und der in einer Schallaustrittsöffnung (5) endet und mit Mitteln zur Verbindung eines Teils des Signalhorns mit der umgebenden Luft, weist der Trichter zur Vermeidung von Beeinträchtigungen des abgestrahlten Klangs durch Wasser im Trichter an einer bei vorgegebener Anbaulage des Signalhorns am tiefsten liegenden Windung (2) eine im wesentlichen nach unten weisende öffnung (3) auf, an die sich ein im wesentlich nach unten weisender Kanal (4) anschließt.
